Packard Bell DB128 personal organiser

Another personal organiser / PDA from 1992. The Packard Bell DB128. Does it work? Is it just needing new batteries? Who knows? Let’s have a look.

What the listing stated:

The Vintage Packard Bell DB128 Deluxe PDA Personal Organiser from 1992 is a charming piece of retro computing history. Manufactured by Packard Bell in China, this personal organiser is a single unit that serves as a reminder of the technology of the early 90s. With its vintage appeal, this item is ideal for collectors of vintage computing devices or those who appreciate the nostalgia of older electronics. The Packard Bell DB128 Deluxe PDA is a unique and rare find for those curious about the evolution of personal digital assistants. Needs new batteries at the very least. For repair or spares only

Packed Bell DB128 personal organiser

I love these postings on the selling sites, no actual real description of the state and condition of the unit you are purchasing, only a potted history of the item with the standard EBay get out excuse of “For repairs or spares only” I know, I can hear you saying, “ Well don’t buy it then – fool” and I agree with you wholeheartedly, I am a fool and I’ve brought it. But, it only cost me £3:30GBP so I’m happy with that, a good price for a bit of retro tech from 1992.

There is a good chance that this unit does only need some power, wouldn’t that be good? However it wouldn’t make very good copy on a site that looks at fixing other peoples castoffs, but I can happily go with the odd quick fix once in a while.

I love these old PDA devices from the 90s, and lots of people do, I guess some of us are still stuck in a period where technology was so wonderfully new and interestingly different. Whereas today everything is pretty much the same and controlled by a few massive organisations, when back in the 90s there were lots of different companies for you to choose your wears from.

I’ve certainly worked on a few on this site, just check the links on the home page to see what I have worked with.

If you are interested in the 90s PDA technology, may I suggest you look at this guys YouTube site. His name is Hugh and his channel is called Handheld Computing and he is a very interesting chap, and the technology is superb. Give him a visit.

Ok. Let’s read a little bit more about this unit:

The Packard Bell DB128 (also known as the DB-128 or DB 1280 IR) is a vintage handheld personal organiser released in 1992. Also known as the Oregon Scientific DB-388P. It was designed as a compact digital databank to store contacts, manage schedules, and perform basic calculations. 

Technical Specifications

The device features the following hardware details:

  • Memory: 128 KB total memory, with a user-available area of 131,070 bytes.
  • Display: An 8-line by 32-character dot-matrix screen.
  • Power: Operates on two or three CR-2025 or CR2032 button cell batteries, often with an additional battery for memory backup.
  • Physical Dimensions: Approximately 15.8 x 8.2 x 2.3 cm, weighing about 252g.
  • Connectivity: Data can be synchronised with a PC via a serial cable or infrared (IR) LEDs. 

Core Functions

The DB128 includes several built-in applications for daily organisation: 

  • Phone Book: Stores multiple contact categories including names, fax, mobile, and email addresses.
  • Scheduler: Features a calendar and appointment system with start/end times and audible or silent alarms.
  • Utility Tools: Includes a 12-digit calculator, home and world clocks, currency/metric converters, and a memo/expense tracker.
  • Security: Offers a password protection feature for sensitive data.

I just have to wait for its arrival now and I’m looking forward to that, I won’t speculate anymore about what might be, I best just wait for its arrival to carry out a suitable assessment.

Assessment:

It’s arrived and good god, it looks as if it’s been stored in a vacuum cleaner bag 🤦‍♂️ it’s utterly filthy, funny how none of the original photos showed this isn’t it? I don’t believe this is the same unit as was in the original posting.

If I’d have taken this into the house with the wife present, i think she’d have murdered me, or at least severely injured me one way or another… So that is why you will see that these pictures were taken at the kitchen sink, the first thing this unit received was a clean with a cloth and warm water. After that it’s had a good polish and it is now nice and clean. Now it can come further into the house, into my domain!

Before and after over the kitchen sink

Now the unit is tidy, everything is as it should be, and the screen is in a good condition barring a few minor age related scuffs. It’s dead, and that’s to be expected, I’m just hoping there are no major surprises awaiting me when I get the back off to have a check inside.

Three screws later and the back is off. All three batteries are still in place, all very dead but fortunately there is no corrosion or battery leakage. All that is visible is some age related tarnishing of the battery enclosure, this however has no effect on the board or electronics and will tidy up with a little brush over with some relevant cleaning solution.

Case off
Battery cover removed

With these little database units you were always supposed to change the two main batteries and get them in place before even considering removal of the single back up battery. This was purely to ensure that saved data was not erased from the memory bank, however as all these batteries are dead, it’s no real issue here. The backup battery is protected with a single screw that needs to be removed to allow access. This unit was able to transmit and receive data using infrared technology. If you look at the picture above with the case off, on the left and the right of the chassis you will see a white diode component, these are the infrared transmitter and receiver parts of the data transfer circuit.

Clean battery contacts
Batteries very dead

The batteries needed within this unit are CR2025 mini cell batteries, I currently only have CR2032 batteries, they look the same but just what is the difference? Thanks for asking, i will now explain.

  • The letter “C” refers to the batteries chemical compound, “Lithium” or to be absolutely precise “Lithium Manganese Dioxide”.
  • The letter “R” refers to the battery shape, in this case its “Round”.
  • The numbers “20” refer to its diameter in millimetres in this case “20mm”.
  • The numbers “25 or 32” refer to the “Height or Thickness” of the battery in millimetres “2.5 or 3.2”

And there endeth the lesson for today. So, in all aspects the batteries are exactly the same, 3 volts, but there is just a slight variation of 7/10 of a mm in thickness. In some cases this is not an issue where there might be that slight bit of space for you to use an alternative cell, however in the case where tolerances are tight such as in watch mechanisms, that tiny difference in size may not allow you to reassemble the backplate to the watch. I hope that clears up the difference between the two coin cell letter and number allocations.

I can use CR2032 batteries in this unit as there is the space. I have some CR2025 batteries on order, so I will comply with the original standard when they arrive. But for the purpose of testing further, the CR2032 batteries will suffice.

Repair:

What repair, to be honest it’s been more of a clean, I’ve cleaned the inside circuit board with some IPA and a brush and cleaned all the crevices with a pick and finished off the outer case with a good coat of antiseptic cleaner and polish. I have inserted the three required batteries and switched the unit on.

All working, all features functional

Not a great deal more I can say. It’s clean, in fact it’s very clean, and fully functional.

Result:

It’s 34 years old, it’s been discarded, put aside for disposal, given one last chance in its chequered life and I purchased it for £3:30GBP. It’s now revitalised, cleaned inside and out and been given a new lease of life. One of those very simple clean and repairs that anyone can do. And another item is saved from landfill.

When turned on

This will now be added to my ever growing collection of old PDA equipment from the 90s, a collection that is starting to grow at quite a considerable rate. I have a few more little projects similar to this in the pipeline, quite similar to this one but requiring quite a bit more attention. Please keep passing by to keep up to date with these “mini” projects.

Once again, thank you for passing by, it is always very much appreciated.

Canon EOS D60

Who would have thought a button the size of a grain of rice could declare this camera defunct and dead. Let’s have a look at it and see if we can get it working again.

What the listing stated:

The Canon EOS D60 DSLR is a digital SLR camera body offered here for parts or repair, ideal for those seeking components or a restoration project.

This digital camera has been tested and does not power on. It is being sold as faulty, for parts or repair only.

Cosmetically, the camera body and battery grip show typical signs of use, such as surface marks and wear. Functionality has not been restored, and no further testing has been performed beyond confirming it does not power up. The battery grip (BG-ED3) is included but requires two batteries for operation; only one battery is supplied. No charger, lens, or additional accessories are included.

Accessories Included: BG-ED3 battery grip, 1x battery (no charger).

EBay

My Canon D60

I’ve purchased this camera kit for the princely sum of £14:24GBP. An absolute bargain, even if it doesn’t work. It’s worth more than that to me, even for spare parts if I can’t get it working, however let’s not go down that route just yet. This camera also comes with a BG-ED3 battery grip that on its own currently retails on the auction platforms for around £20-£30 so before we start I’m on to a winner.

Here’s a little bit about this camera that was released in 2002, don’t get it mixed up with the later EOS 60D that was released in 2010…a different camera entirely:

The Canon EOS D60 is a discontinued 6.3 megapixel digital single lens reflex (DSLR) camera body, announced by Canon on February 22, 2002. It is part of the Canon EOS range, and accepts Canon EF, TS-E and MP-E lenses, but not Canon’s later digital-only EF-S lens range.

The EOS D60 sits in the prosumer (professional-consumer) line of digital SLR cameras. It succeeded the three megapixel EOS D30 and was replaced by the improved, six megapixel EOS 10D.

The EOS D60 features:

  • 22.7 x 15.1 mm CMOS sensor (APS-C)
  • 6.3 megapixel effective (6.3 megapixel total)
  • Max resolution 3072 x 2048
  • FOV crop (1.6x)
  • Canon EF lens mount (excludes EF-S)
  • 3-point auto focus
  • 100, 200, 400, 800, 1000 ISO speed equivalent
  • 30 to 1/4000 s shutter speed and bulb
  • TTL 35 zone SPC metering: evaluative, center weighted, partial
  • Exposure compensation -2 EV to +2 EV in 1/3 EV or 1/2 EV steps
  • Auto White Balance (plus 5 positions & manual preset)
  • Eye-level pentaprism viewfinder
  • 1.8 in (46 mm) color TFT liquid-crystal monitor
  • E-TTL flash mode
  • 3 frames per second continuous shooting (max. 8 frames)
  • Dimensions (WxHxD): 150 x 107 x 75 mm (6.0 x 4.4 x 2.9 in)
  • Weight (body only): 780 gm

Wikipedia

So, as usual let’s await its arrival so we can carry out a full assessment of the camera and related equipment.

Assessment:

The package has arrived, and wow, this is a lot of camera for a very small price.

A lot of camera for little cost

The condition cosmetically is fantastic, I’d call it almost mint but the seller thinks otherwise, he certainly has some high standards, I’m pleased I know him if it means I can purchase items such as this. The only thing that is missing is a small rubber cap that covers the digital and video out ports, not an issue for me, and definitely not detrimental to the operation of the camera, this can be replaced but it really isn’t worth the bother or the extra expense.

The missing rubber port cover

The camera has come attached to the power winder and has a Canon dust cap over the lens mount/body aperture. There is a single battery and this does have some life still in it.

No damage to the CF card reader pins

There is a good quality camera strap attached, and when the battery grip is taken from the body and checked, all battery connections are clean and free of any contaminants. There is no damage to the CF card reader pins within the CF card port. An added bonus is that the body battery cover is tucked away on the power grip handle, and all connections are good, these little battery cover doors normally end up being thrown away so that you end up paying some pirate on the internet an absolute fortune to replace a battery cover door, that in theory is only worth a few pounds. Yes there are many robbing bandits out there! (That’s the polite, non sweary word version)

Battery chamber minus door
Door storage on battery grip

Door and chamber reunited

The camera listing stated that the camera grip needs two batteries for operation, this is not technically true as one battery will still operate the camera whilst using the grip. The option for two batteries just extends the usage of the camera, hence saving you the aggro of changing out batteries when you have a longer camera session planned.

And that one battery does have life in it as I stated earlier.

I know this, because I plugged it into the camera grip, I turned the operating switch on and hey presto, there is life

It’s alive!

So to further test I have removed the grip, and gone back to using the camera with its original battery cover, and then…it doesn’t operate. How strange!

So I then go back to the power grip and everything works fine!

Back to the original battery cover. Nothing again.

I won’t ruin your reading at this point, as to be totally honest if I tell you what was wrong here, I will have nothing to put in the repair section below. Just read on, I can assure you that you will not be impressed. It really is that mundane and boring, you will probably just roll your eyes and question why I have even called it a repair. But a repair is a repair, no matter how insignificant and minuscule it may be, and if it gets the camera working then we are on to a winner.

Repair:

Thanks for staying with me.

Have a look at the three pictures below.

A lever on the battery cover….
Activates a tiny blue button (Circled in red)
That tiny blue button (enlarged photo)

The issue was with the tiniest of buttons. It wasn’t working.

A small tab on the inside of the battery door presses this button when you lock the door. If that tab is broken, or if the switch itself is damaged, the camera may act like the battery is dead or not installed.

The tiny blue button (or sometimes black/white) located inside the battery chamber of a Canon EOS camera is a safety micro-switch that detects whether the battery door is properly closed. It ensures the camera has a solid connection to the battery and that the door is closed to prevent damage. It acts as an instant cut-off switch to prevent data corruption (e.g., if the door opens while the camera is writing to the CF card).

If this switch is not engaged, the camera will not turn on.

And this appears to be the problem. The battery cover was not putting enough pressure upon the little blue switch, the switch also appeared to be a little stiff but soon loosened up when it was cleaned with some IPA and activated a number of times using plastic tweezers. It appears that when the grip was installed and fastened into place there was sufficient pressure to operate the switch, hence the issues I experienced when changing from one battery mode to the other, earlier in this post. Now, when either the original battery cover or the power grip is used, power continuity is restored, and the cameras screen and activities all appear to be working as they should be.

However, we need to now install fully charged batteries, a CF card, and need to get a compatible lens on the front to ensure all the dials, and buttons function and do as they should be doing. I know the flash is definitely working, as this popped up and fired when I was testing the battery earlier, I’m fairly confident we have located and dealt with the underlying issue, though it doesn’t hurt to do a full test of the system just to confirm our findings and to ensure that there is nothing else lingering around, just waiting to be found out.

CF card and new battery installed

I’ve now installed a charged battery and a CF card into the camera, no issue here and all systems seem to be operating ok, no error codes or faults showing. I’ve put on one of my test lenses, a Canon EF 28-80 1:3.5 -5.6, and again everything is good, auto focus and manual focus, all works fine and all settings on the function dial are working just as they should. This camera is doing just what it should be. And appears to be working extremely well in all aspects of operation.

Result:

I’ve taken a few pictures in and around the house and everything appears to be working and functioning as expected. I can confidently state that this camera is working perfectly. It’s not the greatest of lenses as it’s just a test one I use for my cameras, but it proves the point though, that the unit is working and communicating well with all points of the camera.

Looking good and now in a working order

This is a fantastic camera, I only paid £14:24 for a lot of camera dating from 2002, less than the cost of a couple of pints of beer or three coffees, and from my point of view it is an absolute bargain. And it was all down to a little button comparative in size to a grain of rice.

Just a few random pics around the house to quickly test

So I am super pleased with how well this repair has gone, such a simple issue that totally killed the functionality of this unit, easily repaired, all it took was a good bit of investigation, probably taking no more than 20 minutes of my time. I must admit it helps to know a little about how these units function. It always amazes me though, that these sellers could make a bigger return on their items if only they had someone to give these units the once over before declaring them dead and fit for spares and repairs only.

However I’m not complaining as i get to add a superb item to my collection for a very reasonable price. Just browsing the sales sites shows that the basic version of this camera without the power grip is commanding a price of between £140-£150.00GBP, I only paid £14:24. I think I’m the winner here.

There are bargains to be struck out there, if you are willing to give a little time and patience into getting them back up and running. Recycling works.

Many thanks for passing by, it is always very much appreciated.

Yashica 35 ME

An old Yashica camera from 1972 with a non functioning light meter. Time to get it back into a working condition.

I purchased two vintage point and shoot cameras, and this post is related to the Yashica 35 ME. Both cameras were purchased for the princely sum of £4:99GBP and that equates to roughly £2:50GBP each. Both cameras were sold with the following sales statement:

This bundle includes a Yashica 35 ME and Ricoh Auto 35, two vintage 35mm film cameras ideal for collectors or those seeking parts for repair projects.

These cameras are being sold as faulty and for parts or repair only. They have not been tested for functionality and may have issues with their mechanical or electronic components.

Cosmetically, both cameras may show signs of wear consistent with age and previous use, such as scuffs, scratches, or dust. No accessories, batteries, or additional items are included, €”only the two cameras as pictured.

EBay

Having purchased from this seller before, I suspect the cameras themselves are in perfect working order mechanically, but as one camera – the Ricoh, is from 1960 and now in its 66th year of existence, I very much suspect the issue would be with it’s Selenium light cell that is more than likely now very dead. The Yashica however is from 1972 and has a CdS light cell that could also be an issue, more than likely related to the old Mercury 1.3v battery that used to supply it. Either way, even without the light sensors both cameras are very capable of doing what they were built for, however you’d just have to use a separate light meter or use the “Sunny 16” rule. Let’s wait their arrival so we can asses the issue. You can read more regarding the types of light metering used on these two cameras by reading a recent post of mine regarding their differences Photographic light sensors in older point and shoot cameras

Some more photos from the seller:

Yashica 35 ME

Whilst we await their arrival here is a little bit about the Yashica 35 ME:

The Yashica 35-ME is a small, compact 35mm viewfinder camerawith auto exposure, made in Japan by Yashica, introduced c. March 1972. 

It uses a 38mm f/2.8 lens made of 4 elements in 3 groups with a screw-in filter size of 46mm. The film speedis set using a ring around the lens, with the setting window on the bottom face of the lens. The metering system uses a CdS sensor with a sensitivity of 8 to 17 EV. The viewfinder has bright line frames with parallax correction marks for focus distance of 1.5 meters or closer. The shutter display scale is on the right of the finder has speed markings 1/30, 1/60, 1/125, 1/250 and 1/650 of second. Aperture scale is also displayed at 2.8, 4, 5.6, 8 and 14. The setting for the meter uses a pointer type indicator. Correct exposure is assured when the pointer is in the yellow areas of the scales. Also in the finder scale is over exposure, under exposure zones along with symbols of the selected zone focusing settings. The top plate carries the shutter release, hot shoe and frame counter.

Specifications

  • Lens: Yashica 38mm f2.8; zone and feet/metres scales
  • Shutter: Copal auto, speed set by metering, 1/30-1/650 sec.
  • Meter: CdS sensor
  • Film speed: 25 to 400 ASA
  • Flash: hot shoe, flash sync 1/25 of a sec.
  • Power: 1.3v mercury

Camera-wiki.org

It’s arrived, it has that familiar aroma of age old mustiness, but looks a nice item, in good condition for a camera that is now 50+ years old.

Assessment:

The case is quite tatty, but it does the job. The body is dusty but free of any dinks dents or scars. Inside the rear of the camera all is good, it’s clean and the light seals are ok. They will need replacing at some point, but currently they appear to be ok.

Camera looks nice

The winder works fine, the shutter fires and there is no sticking of the shutter leafs.

When you look through the viewfinder it’s a fairly clear view, however the exposure reading needle on the right is sitting firmly on the bottom of the scale. Moving the camera from light to dark makes no difference, the meter is not responsive. Let’s check the battery.

Meter reading does not move

Repair:

The battery that was used is an LR44 cell rather than the old Mercury 1.3v cells that used to be installed on these cameras. They are hard to come by nowadays and people tend to go with the more modern LR44 cells that have a slightly higher voltage of 1.5v. They work, however some have stated that they notice a slight overexposure of about one stop, personally I haven’t really had issues when I have made these battery changes in the past. Each to their own as they say.

The battery currently in place was dead so I tried a new battery to no avail. When I opened the battery chamber again I then noticed some oxidation of the contacts, so a quick clean with some contact cleaner and they looked a lot different.

Before and after battery contacts

A new battery back in place, and hey presto the light meter is now working.

Light meter now working

I’ve given a good disinfectant clean. Buffed up the case to make the best of a bad thing, and it all looks good. The only thing I can do now is run some film through it to give it a final test. I have some old out of date colour film at home, so I will use one of these to run a test roll. As I stated at the beginning there is not really a lot that can go wrong with these point and shoots, and I’m confident that the only issue was with the exposure meter as everything else seems to be fine. let’s get that film run through the camera to check things out.

I’ve taken the film out of the fridge. It’s a roll of Kodak Gold 200ASA film, and it’s only 20 years out of date. I’ve tested a roll of this before, you can see that post here: 20yr old Kodak Gold.

Expired in December……2004

The results won’t be anything spectacular, it will be grainy, it will have a colour cast and in fact might not even work at all. After this period of time the sensitively Will have dropped so I’m going to over expose this roll by one stop to attempt to compensate a bit. This 200ASA film will be exposed on this occasion at 100ASA. When I’ve exposed this it will be off to a local film developer- Classic photo supplies – for them to do the developing and scanning. Read this post regarding my rationale behind using this film: 3..2..1 – 20yrs out of date.

Result:

Well, the scans of the developed film have arrived back and it has proven a couple of things, one that the camera does actually work and two, that the film has definitely reached its limits, as the negatives show immense grain, and a colour cast due to the chemical structure of the film breaking down. I’m glad I only overexposed by one stop, I know that the recommended +2 stops would have been too much for this film. Below I have displayed a selection of pictures from this film, you can see the age related “colour cast” along with grain size if you zoom in. These aren’t the high quality pictures as the originals came back at about 30mpx each, and that would be far too high a resolution to show on this site, and I’d probably use up all of my photo allowance as well. So here are the greatly reduced results of those scans.

Back gate
Forklift
A house view
Driveway
Train passing

Storage

To be totally honest if you switch to B/W in editing mode, all the pictures come out fine and are completely presentable and maybe that’s the way to go with the next batch, don’t bother trying to get a good colour balance as that will never be achievable, just display in good old black and white, you can’t go wrong.

So the camera works, and this one will now be put aside until I decide how I’m going to move it on. It’s such a basic camera, the distance selections are questionable, but that’s just a remnant of the 70s technology behind it. It’s a good little point and shoot, but I do believe the likes of the Olympus trip totally outshone all other competitors in the point and shoot category.

Job done. Another old camera saved from the scrap heap, and given a new lease of life, and it probably took no more than 10 minutes to get it back in working order.

Thanks for passing by, it’s very much appreciated.

At last, the new work space takes shape.

The workspace is starting to take shape. Normal service to resume soon. Maybe I can catch up with this backlog now.

I’d pretty much closed down my workspace, when we sold our old house back in August last year. Everything I used the most was pretty much moved into storage as we prepared to make the move to our new home. All I was left with was a few screwdrivers, so needless to say, content on this site dwindled, whilst purchasing continued, hence I currently have 29 posts, in draft, awaiting completion as I don’t have a suitable workspace or the equipment available at the moment to complete any of them. I even purchased a 3D printer in November of last year for my birthday, it has been in storage all this time, I have now brought it home and have now made my first 3D print, that post can be found here: My First 3D print attempt

Things are about to change.

We pretty much have every room in the house now up and running. We are settled now and the final boxes have been attended to within the house, and we are finally getting to the point where regular recycling visits to the tip to get rid of the old cardboard boxes are finally coming to an end.

The next stage in my wife’s own words are, “ we can now get Dave’s room sorted.” The words I’d been waiting for.

My workspace – a wall in a guest bedroom

I’m calling it my room but in theory it’s not a whole room. It’s part of the third bedroom where I am probably just occupying one wall at the end of a guest bedroom, it’s all I need, I have a Garage to do all the blokey stuff in, this space is purely to work upon all my cameras and other more delicate items of work.

Whilst visiting a certain Scandinavian furniture store i have purchased a basic setup for me to begin working on. The good thing about these furniture systems is that you can start with a basic layout and just expand upon it, and that’s the plan.

I have a desk and drawer system arriving today, and quite a bit of construction to do, once this is in place then I can start getting my gear from storage and get it back into place. It will be nice to have all my equipment in a permanent placement, without having to take it all apart and storing everything back in boxes after I have used it. I’m looking forward to this as to be honest, I’ve really missed it. However I have been pre occupied around the house and there has been an awful lot to keep me busy, there’s been no rest really, I must be very wicked 😂

The workspace starting to come together

So as of 10th March, I’m quite pleased to say that my workspace is now ready to use. It’s still a way from being complete as I still have stock to bring from storage along with the last few tools and boxes of components. There are still shelves and storage to put in place, but at long last I can now sit down and finally start to play catch up with my ever expanding backlog.

The workspace….liable to be moved about yet again

I must admit I’ve moved things about, and I’m probably liable to move things about again over the coming days and weeks, even months as I can’t quite decide how the setup should look. It’s probably going to be a few sessions of me not being able to find tools, parts and cameras that will help me decide just what, should be where. In the meantime, it’s good that a kind of normality has been restored, and I can now start to resume where I left off all those months ago.

My First 3D print attempt

I’ve had a 3D printer for 4 months now. I am now able to use it and today I have produced my first 3D printed item. A Poop bin. Yes you did read that correctly….

Those of you who watch this site with eager anticipation (I’m joking 🙃) may remember a post that I published in November of 2025, when as a result of all the money I received as gifts for my birthday, I went out and purchased myself a Bambu PS1 Combo 3d printer: I’ve taken a dive….

My Bambu PS1 Combo

I’ve not printed a single thing 3D in my life and to be quite honest I haven’t got a clue on what to do, but as usual I’m willing to learn. I’ve had a number of occasions over the past couple of years where I’ve needed an obsolete part for a project, I’ve had to go as far as Italy to get parts printed whereas with this equipment I could have done so my self, cogs and gearing are a regular item that I come across that I could also use this equipment to produce. See, it will serve a use to me once I have my workspace configured.

That time has arrived….

Now we are safely moved in to our new home, and all the important stuff has been attended to, attention has switched to getting my work area up and running, and I will shortly be uploading a post regarding the inside my work area.

However, this piece of equipment has been in storage since November, almost 4 months now and needed to be put into action as soon as possible. Seeing that the workbench was now in place it only seemed right that the printer was now unpacked.

It’s a big box, and has a lot of packaging

Even to do the unboxing there is a QR code to link you through to the process to follow, it is very informative as these printers are packaged so well, there are screws and supports to remove, put in place to stop sensitive parts being damaged or dislodged during transport.

The AMS system installed on the top of the printer

When you follow this system of unpacking, you are also linked to an app called, “Bambu Handy” that really is the control system for your printer. Here you register, set up blue tooth and WiFi options and the app then becomes your monitoring and control for your printer. At the moment I’m sticking with just this app, once you are more experienced there are a number of more complex programs you can then use for design and editing purposes. For now I have found my level. I now install what is called the AMS system on top of the printer, it is an automated feed for using more than one coloured filament, the printer can move from one colour to the next automated, without interrupting the print process.

But that creates a little waste product….

And there is my first print project.

When the printer initially primes, or when it changes colour it will create a little waste as it clears the nozzle of one filament to use another. This waste then exits the rear of the printer onto the floor, or work bench depending on the positioning of your printer. For this reason people then install what is known as a “Poop bin” to collect such waste. Here is a draft picture of the one I will print for this printer.

A draft “Poop bin”

Now, this app fortunately comes with absolutely thousands of pre programmed prints covering all aspects of printing technology from home, toys, educational and everything in between. Fortunately, because “me” as the totally clueless, doesn’t have to learn basic CAD and slicing techniques, because some clever individual has already done that for me. And for that I am very grateful.

There are a number of tools and equipment you can print for these printer units, it’s as if they are self maintaining and developing. All very clever stuff.

But a “Poop bin” is a necessity if you don’t want to suffer the wrath of your other half by spewing out randomly produced plastic waste on to her nice new carpets. That is not conducive to a happy and peaceful existence 😂

So a “Poop bin” is my first ever 3D project….so here goes.

A simple selection on the app, of the item you require, a few settings get amended, the printer does some calibration checks and then the process starts, this particular print takes about 4.5 hrs to complete. Fortunately the system has an inbuilt camera so you can check progress or even get a timelapse at the end. You can basically shut the door, turn off the light and walk away, you can always check in, but sitting there just watching for 4.5 hours can get a tad boring, and is just like watching paint dry, so why not just walk away and do something more useful. I did just that, and went to assist the wife with some chores.

Here is the said timelapse of the print. 4.5 hrs in about 30 seconds. The dark periods are brief and were just me messing with the onboard light settings.

My 3D poop bin printing

Here’s the actual finished article, and situated at the printer.

Printed item, and in place

So that’s it really. Still learning but quite happy with what’s been learned so far, the desk and everything needs some fine tuning and there is a lot of gear still to be added but we are now off to a flying start.

Current position with anti vibration feet now installed

One thing I did notice was that there was some vibration and noise, however I did get gifted some anti vibration feet with the package when I purchased the printer, I have now installed these so hopefully the next print will be a little bit more peaceful, not that it was particularly bad anyway.

And that concludes this post. Thanks for reading, it’s always appreciated and I hope this day finds you well and at peace.

Toshiba Camileo X400 Camcorder

Let’s have a look at a non functional Camcorder from 2011 that appears to have bathed in molasses as it’s so sticky. Can I get it working once more? Why not?

What the listing stated:

It has not been tested but outside case is sticky. 
Would recommend for spares and repairs only

EBay

Toshiba Camileo X400 Camcorder

Not one of the finest quality camcorder cameras out there, but for £7.00GBP, I’m not really complaining. This camera appears to have a battery included, it has no charging equipment or anything else included, but I’m hopeful there’s not too much badly wrong with it. However as this is a platform for repairing old knackered equipment, hopeful there is something that we can get our teeth into that is sufficiently suited to this platform. All I can currently gather from the listing is that this a bit sticky, and those of you who follow this site will know that stickiness, especially on cameras is not an issue that has caused me any problems previously. Hopefully the issue is a little more than just stickiness, and as this listing has the classic EBay “Get out of jail free – seller not tested” claim, then there could be absolutely anything and everything wrong with it, we will just have to wait and see.

Here’s a little bit of background for this camcorder.

Toshiba’s CAMILEO X400 Full HD camcorder offers 1920 x 1080p video capabilities, 23X optical zoom, and other great features for taking great video and making great memories.

No matter what you’re looking at, the CAMILEO X400 Full HD camcorder takes jaw-dropping video in 1920 x 1080p resolution. You’ll be able to capture all the color and clamor of that Fourth of July parade, or your daughter’s first soccer goal. And with the 23X optical zoom, you’ll see the big smile on her face, too.

Want to follow your baby as she takes her first steps? Follow your friends as they head up that mountain trail? Record your Jeep ride across Africa’s Serengeti plain? Go for it. The image stabilization capabilities on the CAMILEO X400 Full HD camcorder ensure your ensuing creation will be hunky-dory, not herky-jerky.

Video trimming on the CAMILEO X400 Full HD camcorder makes editing easier by letting you cut out a section of the video from the front, back or both–plus start and end the video at any point you wish. What’s more, with a built-in pause button, you can stop wasting storage space and reduce file clutter by recording multiple scenes into a single file.

Your son just learned to surf and caught a nice point break for a good long ride. Want to freeze the frame for pictures you can share in an album, email or hand out to friends? Do it without interrupting the video. Simply press the Photo button* on your CAMILEO X400 Full HD camcorder and your surf dude will be immortalized forever.

Well, to be honest that has to be one of the worst background write ups I’ve read, and in reality the tone of it doesn’t fill me with confidence, all that talk of “Dudes” and “Hunky dory and Herky Jerky” my god, who do they let write this stuff? This camera didn’t stand a chance to be honest right from its release date in late 2011.

So, let’s forget the awful promotional write up, and just like true “Dudes” try to find out what is actually wrong with the damned thing.

Assessment:

It’s arrived and to be totally honest, it’s in a right poor condition cosmetically. Very poorly packaged, I suspect the seller couldn’t wait to get it out of the door. Here are two of the better looking pictures.

The good…

As soon as you pick the unit up, the stickiness the seller wrote about becomes obvious. It’s as if this camera has been immersed in a vat of molasses, it’s super sticky and if you review the close up pictures below you will see this unit has obviously been involved in some sticky situation, in places it is still wet, with liquid clearly visible, however that liquid is in a super sticky state of suspension.

Sticky Liquid
Wet, with protective film still in place
Dirt and stickiness
Just plain filth

…The bad, and the very ugly

The battery is in place, I suspect it is dead but it will need to be tested, thankfully the battery contacts are clean and luckily it appears that no liquid has managed to reach these areas.

Battery – possibly dead
Battery contacts all clean
Somewhere clean..hallelujah!

Before I even start to look at anything with this camcorder, a very thorough clean is the order of the day. It’s not going anywhere, and I’m not doing anything with it, until it is in a more presentable and workable condition.

I like to use a disinfectant spray when taking on a job like this, in fact I use it on most of my old cameras especially those that have an old musty aroma. The disinfectant has cleaned this unit up very well removing all of the old stickiness and residue. I finish off with some polish and a cloth and the beast has now been cleaned and is now in a much better condition to start looking at where the problem may lie.

A good clean and it looks like a different unit

Well, to be totally honest the unit is kind of dead. There is a minimal voltage in the battery and when I find a suitable charging cable and install it, there is not a great deal else occurring. There are some lights, but they are not doing what they should be doing, I’m expecting lights to flash whilst charging, and a solid light when charged. However this isn’t happening, so let’s move on to what we are going to do to try and resolve this issue.

Repair:

For the moment I’m going to focus on the battery. We need power, so we do really have to start here, we can’t diagnose or do anything without some power. It’s a 3.7v Li-ion cell, and the camera can charge via a 5v USB supply. I’ve managed to locate a suitable charging cable from that drawer of collected cables that “may come in useful one day”, that we all seem to have stashed in our homes. When the cable is plugged in you should get some intro music from the camera, and I do. This should then be followed by a flashing light that should remain lit until the battery has sufficiently charged. However I manage to get about two flashes from an amber light and then that’s it… nothing else. So far it’s positive that we have seen some life, however we need to see if we can encourage this battery to take a little more charge.

These batteries though rated at 3.7v usually charge up to 4.2v at full capacity. I’ve just measured this one with a multimeter and it currently sits at 2.64v. In the world of batteries this is severely depleted and to be totally honest looks as if this battery is dead.

A fully charged 3.7V nominal battery typically reads 4.2V, with 3.7V-3.8V being the average voltage during discharge. A 3.7V Li-ion battery is considered “dead” or fully discharged when its voltage drops to 3.0V to 3.2V.

While many protection circuits cut off at 2.5V to 2.75V to prevent damage, discharging below 3.OV frequently will significantly reduce the battery’s lifespan.

2.64v This battery is more than likely dead

And it looks as if this may have occurred here. It’s looking as if the battery is a dead one.

However, I’m going to see if I can rejuvenate this battery by putting a trickle charge through it, just charging it in the camera from a USB 5v power supply. I will monitor regularly for changes in temperature or other issues. I don’t have a spare around at the moment so if I want to do some basic checks on the unit I’ll just have to give it a try.

Dead at 2.6v
After an hour we have 3.5v
After 2 hrs it’s now 3.56v
After 3 hrs it’s now 3.6v
Slow work

So after 3 hrs we’ve only been able to get about another 1v of energy into this battery, and as you can see we are only just into the battery depletion range. We have sufficient power to start the unit up and see a welcome screen, the zoom works. It’s clearly visible that there is a low battery indication on the screen and then it all shuts down again.

Welcome screen
Battery indicators all red

There is just not enough life in this battery to sustain a 30 second video, the battery is just so worn down that I believe it is beyond resurrection. I may have to purchase a new battery to finish off this section of the post. It’s good though that we have tried, rather than just give up, and this has also allowed us to review what we have found out about the process, and the good news is that at this point it, is looking as if it is purely an issue with this battery.

The camera has cleaned up lovely and really looks like a nice piece of kit. For the moment I will put this post on pause whilst I await a replacement battery.

But…. Me being me, and not wanting to spend too much money at this point, I have persisted with leaving this battery on trickle charge. It has been consistently monitored to keep an eye on it, and I must admit neither the battery itself or the charger has been hot or even warm throughout this entire process, that is good.

Four green lights – Fully charged?

Seeing that about 4 hrs ago the battery indicator on the screen was only showing two green bars, it is now showing four bars and that indicates it is now fully charged. Let’s get the multimeter back on, and check to see what the current battery charge is and see if that gives us an indicator to show if the nominal charge has now been achieved, I’m quite excited at this – I’m easily pleased and excitable in equal proportions – I have a feeling that with patience and persistence we may have well just cracked the issue. So what is the current voltage of this battery? Well, here it is….

4.14v

Full charge achieved

Well, I’m very pleased with that, not only has it charged fully it appears to have reached pretty much full charge beyond the nominal charge. I’ve probably saved this battery from the trash heap, but I guess it will be more of a backup battery for me as I will probably purchase a new one, for my main battery, now though, there is no rush as it looks as if this one has been rejuvenated.

I’ve put a 32Gb SD card in and the screen is indicating 5 hours and 54 minutes of recording time, however on a full battery and using the minimum of activity (Not using Zoom and other effects) you can normally squeeze two hours of recording from the battery. But I’m never going to be filming war and peace, and I’m probably never going to get that kind of usage from this battery. My best bet with this battery is to not let it deplete totally, and try to keep it in a charge cycle were it doesn’t dip below about 25% of its capacity if I can help it.

I’ve tested all settings and everything is just fine. The touch screen is responsive and all setting and special effects can be easily accessed. There is nothing else wrong with this camcorder.

Available recording capacity
Touch screen working well

At this point I am now happy that this camcorder is a fully working and very capable little unit, that should serve me well as I use it to make videos for my YouTube channel and WordPress site. Repair is complete and successful.

Result:

This little camera cost me £7.00GBP and it’s been a fantastic restoration as such as it has not cost me a penny more than what I have paid for it. All I have done is invest time, done a lot of reading up about the intricacies of Li-ion power supplies, and done an awful lot of cleaning as this unit was probably one of the filthiest pieces of kit I think I’ve ever worked on.

A video, of me, videoing a video of me videoing

The camcorder is now a totally different looking camera from that which I received in such a sorry state just a few days back.

A nice camcorder, clean and restored

I’m going to use this camera myself for little items that I will be publishing here as well as on YouTube. It is so wonderful to see old unused and unloved items, repurposed and given a new lease of life.

Another one saved from landfill.

Thanks for passing by, as always it is very much appreciated.

Meshtastic

Ever heard of the Meshtastic decentralised off grid communication network? You have now. Dive in and get involved.

What’s that? I hear you say. Well, I’ve been trawling t’internet recently and one of the chaps I follow on YouTube, Gabe, has got me very interested in this particular mode of radio communication. Here’s a video of him explaining Mesh communications in his own charming and extremely enthusiastic way.

Meshtastic – as Gabe sees it

The good thing about Mesh networks are that no licence is required for use, this means the system is truly open to everyone. As a registered radio amateur this system is of interest to me in the spirit of experimentation, and that’s what’s good about this particular mode. Everyone can do it at a very reasonable cost. In the UK it’s been present for a few years now and has an active core of participants. However, usage is very patchy and still developing, and due to the short range and lack of other users to repeat messages, its general take up is going to take a while yet, or in usual fashion it may even be a mode that just dies out due to lack of involvement. It’s not a mass-market tool yet, but a growing niche interest, especially among amateur radio, DIY tech, and preparedness communities. However, that said, in areas with little or no cell phone coverage this could well be a lifesaver. Below is a little bit about Meshtastic.

What is Meshatastic?

Meshtastic is a free, open-source project that lets you create your own decentralized, off-grid communication network using LoRa (Long Range) low power radios. It’s designed to let people send short messages and share data without relying on mobile networks, Wi-Fi, or the Internet.

Open-source & community-driven: Anyone can contribute, modify the software, or build devices with the firmware.

LoRa technology: Uses low-power, long-range radio waves in unlicensed frequency bands (like 868 MHz in the UK/EU).

Mesh networking: Devices form a mesh by rebroadcasting messages. Each device acts as a node that can relay messages to extend coverage.

Meshtastic’s goal is to provide reliable communications when other infrastructure is absent or unreliable and to offer a flexible platform for hobbyists and practical users alike.

How it works

Networking: LoRa radios transmit small data packets over long distances with very low power. Each device forwards messages it receives to nearby devices, forming a mesh network that extends reach beyond single-hop radio range. The network is decentralized — no central tower or internet access is needed.

User interaction: Devices can connect to your smartphone via Bluetooth and use the Meshtastic app to send messages or view locations. Messaging is typically text-based (no voice or high-bandwidth data).

Why use it?

People adopt Meshtastic for many reasons, often tied to availability, resilience, and independence from traditional networks:

Outdoor activities: Hiking, camping, biking: Stay in touch where cell signals are weak or absent. Location sharing: Useful for groups and safety.

Emergency situations: Natural disaster backup, communications can continue even if cellular networks fail. Communities and some groups experiment with using Meshtastic as an alternative communication layer during outages.

Technology and DIY: Education and hobbyists use it to learn about radio, mesh networking, and embedded systems. Integrations with IoT sensors and other projects are possible.

Community and social projects: Enthusiasts set up community networks, share nodes, and even run local meetup groups. 

What do you need to get started?

Basically, Amazon, EBay, and the Chinese suppliers such as Ali express have all you need. Needless to say the Chinese options are far less expensive if you are willing to await delivery. Just type “Meshtastic kit” into your browser to view your options.

As I’m in the Uk I can give some prices for the most basic setups within my country. To be honest, all that is needed is a Meshtastic main board of which there are a few to choose from, a power source and a mobile phone to do the setup. Something like this below.

From Amazon in the uk I can get this board, for £18:99GBP and that’s all I need to get started.

Amazon uk

Add to that a small battery and you can probably power this unit for between 24hrs or even a week, dependant obviously on the battery capacity and how you have the system set up. A battery in the uk on Amazon would cost around £6-£10 GBP. You can buy enclosures to make the unit “pretty” or you can even 3D print your own. I think I will print mine when I finally have my printer up and working.

A suitable battery

On the Chinese platforms these items can be purchased at a greatly reduced price, the main board can be purchased for around £3:00GBP, you can even purchase two entire units for less than the one that you get from Amazon. It really pays to shop around.

I’m shortly going to dive into setting up a Meshtastic node, I’m even going to set up an APRS one under my radio licence conditions, but that will be another post.

So hopefully this post may introduce others to an off grid communication mode that may well assist those in remote areas or with extremely limited cell phone coverage. As soon as I’m ready to build and place my node I will write a post regarding its build, programming and eventual usage. It is all very simple technology and worth having a read about on the Meshtastic website : Meshtastic introduction

Text you soon!

Canon power winder “A”

A very corroded Canon power winder “A” from the 70s

This is what it looks like externally, looks fine, but as this post goes on, you will notice a very marked deterioration in quality. It’s a horror story of battery acid contamination.

Looks nice

This unit is part of a bundle that was donated to me by my good friend Jon, see here: Cameras…i need more!

It was part of a Canon AE1 combo, the Camera i have previously posted about here: Canon AE1 35mm SLR, however the batteries within it had been left for such a long time that they had started to dissolve into the unit, leaving quite a restoration project behind. Here’s some history about this unit:

The Canon Power Winder A was originally introduced with the Canon AE-1 camera in 1975 but it also can be used with all the A series models (in fact, it is applicable to use the Winder A with the professional class Canon F-1(n) system SLR camera but without power rewind feature). It is an automatic film winder which greatly increases the automation and mobility of these manual focus cameras. Its exceptional versatility, due to its compact design provided by the principal control circuit built into the electronic circuitry with most of the electronic models such as AE-1, A-1 or AE-1 Program etc, and allows it to be attached to any models mentioned earlier and provides for its use without any special adjustments. 

Winding Speed: Approximately 0.5 seconds.
Operation: When the shutter button on the AE-1 is pressed, the winder will function. 
Shutter Speed Coupling Range: 1/50 to 1/1000 second for continuous photography. “B”, or 2 to 1/1000 second for single frame photography. (When the winder is set at “B”, AE photography cannot be performed).
Film Counting: Is performed by the frame counter on the AE-1.
Automatic Cut off Circuit: When the film roll is completely wound up or if the batteries should run out, the winder will automatically stop and the warning lamp (LED) will light up.
Power Source: Use 4 size AA batteries. (In normal temperatures they can take more than twenty rolls of 36-exposure film).
Attachment: Take off the winder coupler cover on the bottom of the camera, and mount the power winder using the tripod socket.
Size: 141 x 42 x 34mm (5-9/16″ x 1-5/8″ x 1-5/16″) 
Weight: 3009 (including batteries) (10.9/16 ozs.)

Mir.com

I already have one of these winders on my A1 that I am currently repairing, however that’s away in storage at the moment until I get get my workspace back up and running when we eventually move home.

Im aware that these winders can take a max of two exposures per second if the lighting and conditions are right, meaning you could crack out a 36 exposure roll of film in under 20 seconds! They don’t do auto rewind either, you still have to do it manually, it would be a couple of years yet before that option became available. The red light on the case indicates one of two things, the battery is low, or the end of the roll has been reached, time to rewind!

They are quite reasonably priced if I wanted to buy one, but why would I do that? The purpose of this site is to repair and recycle, so that’s what I will attempt to do. It will be quite a task with this one I think.

Assessment:

As stated above, and from the outside, all looks well.

Outside, cosmetically, no signs of a problem

However there are a couple of giveaways that alert you to the immediate issue. Firstly there is an aroma, a kind of metallic musty smell that instantly alerts you to “Corrosion”. Secondly near the switch there are some “blue” granular stains that confirm corrosion.

We start to open up and find signs that all is not well
The old corroded batteries
The contacts, and the battery bay

It’s pointless even putting batteries in here yet as they will not work, the damage is too extensive for the batteries to work. To be honest we now need to do a good clean and decontamination before we can even start to look at the extent of the contamination.

Repair:

First we have no choice but to get rid of the corrosion, this will involve brushes, a pencil grinder, and copious amounts of isopropyl alcohol. Let’s get started.

Using a sonic brush and IPA

I attack the contact end of the winder with a sonic brush and some IPA. After about 10 minutes and multiple applications, using a small scraping tool i was able to remove the corrosion that had started to eat away at the chrome on the contacts, a small rub with some fine sanding paper restored the metal as best I could. I’m not going too over the top here as the corrosion could have well gone past this point into the internal workings, I’ll tidy up once I can get it working as it should.

Before
After
The battery compartment

The battery compartment was cleaned using a similar process. However the contact end that used to have springs mounted for the batteries, have all rotted and the springs have had to be removed. I will replace the springs later, it’s not required for testing purposes just yet. All this contamination and blue staining has to be removed completely, if you leave contamination behind, it can start to attack the unit again at a later date, take your time and ensure you get as much off as you can. Clean, clean and clean again. It’s a boring part of the process but essential for long term results.

With everything cleaned and left to dry, I put some power across the winder power contacts and nothing happens. No noise, not any sign of clicking or of any movement at all. Just as previously feared i think the corrosion has gone further. Let’s get it opened.

Leatherette removed to access internally
Corrosion has made it inside

And as expected the corrosion has made its way inside, the picture above shows a wire at the contact point rotted due to corrosion, in fact the second wire fell off just after removal, the contamination has eaten the cables and is rotting the connections. The good news is that it seems that the issue hasn’t gone beyond these contacts.

I’ve now cleaned and polished the contacts at the rear in preparation for being re soldered, the issue here is that I may have to extend the cables slightly as they are quite short. This may aid my testing of the unit prior to reassembly, let’s wait and see.

I have now soldered both contacts back into position, without any extra wire, hell, it was really fiddly and I doubt it would be able to be opened again without these wires being extended a bit further. I have also thoroughly cleaned throughout the internal workings removing all signs of contamination. I have reassembled the unit and it now sits in one piece. I have taken a dentist tool to further scrape down the contact point within the battery barrel area.

Further cleaning of the contact in the battery barrel area

Using a little wire wool and IPA to clean the area I now have two good points of contact. Using the multimeter confirms we have continuity over the contacts that we didn’t have previously.

Reading the section above, you will remember that I had to remove the two springs on the battery case as they had totally corroded and broken away. I have some new ones but they are in storage, so for now I will just have to compromise until I can get to the new ones and solder them in place. Here I just obtained an old spring from a waste metal box, split it in two, added a small washer one end for the positive contact and just left the other as it was. Both springs were put in place, just being held there by the four AA batteries. As I stated this is purely for testing purposes and will be corrected once I have confirmed the unit works.

Temporary springs
Held in place by batteries

The battery holder was attached and then switched on. Nothing. Then I remembered I have to simulate the signal from the camera and this can be done by putting a metal short across the two raised pins at the power switch end. This worked, and the motor did its quick burst as expected. See the small video below.

The winder, now working. And shorting the pins to simulate the cameras signal

I’m pleased with this, as all the work I have done has been worthwhile. I just need to get the new springs soldered in place, give the whole unit a thorough final clean, ensure the leatherette that was removed is stuck back down and that the on off indicator is stuck back into place. And then we can put it onto the Canon AE1 to see if it works as it should.

Leatherette now glued back in to place
On / Off switch plate glued back in place

Today I have taken out the battery spring connector and I am about to put the new spring contacts in place. I’ve found even more corrosion behind this plate so this will need to be cleaned before reassembly.

More corrosion found behind the battery spring contact plate

I’ve now fixed the new permanent springs in place, they wouldn’t solder so I’ve had to use a combination of using the old clips that were originally there and weaving the spring though the holes where some clips used to be but had corroded away. Either way it has worked well and both springs are quite solid, and don’t look out of place at all, they probably look better than the originals.

New springs attached to a clean plate

With the battery pack contamination removed I can now reinstall the battery contact back into place.

All cleaned
Reinstalled
Batteries in place

I know that the pack works, and now the final touches have been added, this winder is now back into a good working order, and fit to go back to work doing what it was originally designed to do.

Result:

This is an item you can readily buy on the auction sites at a very reasonable, some would say even very cheap price.

The complete, cleaned and reassembled, working winder

Is it worth the repair you say? Well yes, it is. The trouble is, it is so easy to throw stuff away these days, that in reality, can be given an extended life and purpose for pretty much no cost apart from your time and patience. On top of that, getting these items apart and reassembling them is a great learning circle, and you can never stop Learning. You are preserving the past, and that’s always a good thing.

A very brief video showing it working

As you can see above in this small video I have taken today, here I have my Canon AT-1 with the winder attached, doing what it is meant to do and sounding so retro with that motorised winding sound. Don’t you just love it? I most certainly do.

Thanks for passing by. It’s always very much appreciated.

Sharp OZ-7000 Wizard

The Sharp OZ-7000, Amongst one of the first electronic organisers and precursor the PDA. Needs repair. Or does it?

What the listing stated:

Not working. I have replaced the two batteries and cannot get it to work. I have not touched the memory battery. See picture for actual item. Case is a bit sticky unfortunately with age.

EBay

First of all, what is it?

The Sharp OZ-7000 Electronic organiser / Calculator

The Sharp Wizard series, introduced by the Sharp Corporation in 1989, was among the first electronic organizers and a precursor to personal digital assistants (PDAs). The debut model, the OZ-7000 (known as the IQ-7000 in Europe), combined organizer functions with an IC Card expansion system, allowing users to install software and memory cards. Over time, Sharp refined the series with larger displays, increased memory, and enhanced features, such as infrared communications port for wireless data transfer, touch-sensitive displays, and clamshell designs.

The out-of-the-box functionality of the OZ-7000/IQ-7000 included a memo pad, a telephone pad, calendar and scheduling with alarms and repeating events, multi-time zone clocks, and a calculator, thus covering all the basic functions found in PDAs since. The keyboard was not QWERTY, although later models, starting with OZ/IQ-8000, changed the orientation of the screen and keyboard layout.

The OZ-7000 was about 6.3 inches (163 mm) tall, 3.7 inches (94 mm) wide closed, 7.25 inches (184 mm) open, and 0.85 inches (21.5 mm) thick closed, making it much larger than later PDAs. It featured a serial port (proprietary connector) to attach to a Windows PC or Macintosh or another OZ-7xxx/OZ-8xxx device, an optional thermal printer port and a cassette tape backup. The OZ-7000/IQ-7000 model featured 32 kilobytes of internal memory and a 96 x 64 dot (8 lines x 16 characters or 4 lines x 12 characters) black and white LCD with controllable contrast but without a back light. A major advertised feature of the model was the IC Cards expansion slot for accessory cards developed by Sharp.

A bit of a break from the mountain of photographic equipment I have been dealing with lately, I thought I’d take a bit of a detour and have a look at some prehistoric PDA gear, as I have also done in the past, as you will no doubt be aware of, if you have ever read any of my posts on Psion organisers.

From what I can gather, this one is a little beaten up and battle scarred, and quite simply does not work. I’ve paid the princely sum of £8:54GBP after i managed to knock the seller down by a few pounds. I just now have to await its arrival before we can carry out a thorough assessment.

Assessment:

Its here, everything is as it should be apart from the base being a bit loose in one corner where the clip inside has broken, however that’s not an issue and can probably be repaired.

The broken clip

The exterior is a little sticky but again, this is just one of those 1989 rubber enhanced products where the vulcanised rubber coating has started to degrade. A post I previously published shows how I deal with these 80’s degrading rubber issues: Sticky, Rubber camera grips

Both sides of the case are sticky and require cleaning

The unit has three batteries, under the rear shell. These are two CR2032 and one C1616 coin cell, with the C1616 being the units memory battery. These batteries will need to be tested as this unit does not start up, the whole unit is dead. The previous owner has stated that they have changed the two main batteries but not the memory battery, testing them will tell.

The three batteries

Beyond that, all catches, buttons and switches seem to be performing as expected, no cracks or major damage to the external shell, or screen area. Naturally there are signs of usage as you would expect on an item that is now 36 years old, light signs of age related wear and tear, nothing of concern that is detrimental to its operation.

Repair:

I’m leaving the broken clip on the rear shell as it is, it’s not visibly exposing anything of the interior and to be honest needs quite a bit of force to show the gap, it’s not a problem and not necessarily requiring a repair. In normal handling it is not even noticeable, so it will remain as it is.

The main fault, and I apologise in advance, as it was not really a fault, was a misunderstanding of the unit’s operation by the previous owner. When you take the back off and change the batteries, you have to operate a switch so as to not interrupt the backup of the system.

Battery backup switch there is a “B” and a “A” setting

There are two modes and these are explained below. This switch is located inside the battery compartment and is used when replacing the main batteries to prevent data loss.

  • B stands for Backup, a setting used during the battery replacement process. The device relies on a small, separate backup battery (often a C1616 coin cell) to maintain memory while the main batteries are removed, provided the switch is in this position.
  • A stands for Active (or simply the normal operational position), which is the standard setting for everyday use once new batteries have been installed. 

To replace the main batteries safely and avoid losing your data, you must follow a specific procedure that involves setting this switch to “B”, changing the main batteries, and then switching it back to “A” after the new batteries are inserted. 

The issue here was that the batteries had been changed and the switch was put into the correct “Backup” mode. However the previous owner had not placed the switch back into the ”Active” mode when the batteries were changed and the back of the shell was put back in place. Hence the unit would not work as in theory the batteries were locked out of use. On opening the shell up, this was the first thing I looked at, and when the switch was put into the correct position the unit sprung into life once the “On” button was pushed.

When the switch was set, power applied and the unit reset to 1989

When the unit was turned on it then reset to 1989, I was able to change the times and date, and I was pleasantly surprised to find out that the date range on this unit covered the years 1901-2099. Considering this unit was released 11 years prior to the Y2K bug of 2000, it showed some advanced thinking in the implementation of these units.

Happily updated to the current date and year

One of the issues with this particular unit is that there is no backlight on the display, the display is black and white and the only change that can be made is to the contrast. Back lights eventually arrived with later models. So use of these units was pretty much limited to daylight hours, or whilst under a light source of some kind, that said the display is very good and has a good contrast range.

The last thing I have done is clean with some IPA to remove the years of gunk and I think this was quite successful

The IPA certainly lifted some dirt

After this I have finished off with a nice polish with some car cockpit cleaner. It’s finished this repair off just nicely.

Result:

Here we have a nicely presented, clean and fully working example of a nice little bit of personal computing history.

So. With these older items, it’s sometimes good to just have an awareness of how these old timers operate. Get an instruction manual, study how it works, it can make the difference between selling it as damaged, when in fact there really was nothing really wrong with it. The seller could have sold this for 3 or 4 times the value that I purchased it for, but I’m not worried about that, as far as I’m concerned I got myself a bargain and to be honest, that doesn’t happen that often.

It’s a win win situation as far as I’m concerned, I win as I now have a lovely example of pre PDA technology, and it’s a small win for the environment as another piece of “Waste” has been saved from landfill.

Thanks for passing. Thanks for being there. Always appreciated 🙏
