At a family gathering this weekend, an elderly family member approached me and asked if I could take a look at his Panasonic personal tape player, and maybe get it back up and working.
Who am I, to turn down such an invitation, so I took it on and promised him I’d have a look into it. There is, “No rush“ I was told. Just as well, as it’s busy in every aspect of my life at the moment.
Here’s the spec:
Type: Auto Reverse Cassette Player
Tape Type: type I, CrO2, Metal
Output: 20mW
Battery: 2 x AA
Power Supply: RP-AC33 (3V DC)
Dimensions: 114.2 x 84.4 x 33.1mm
Weight: 156g
Finish: black
Year: 1993
Hifiengine
Panasonic RQ-P250
Assessment:
It’s well used, and has always been and if I can get it working, will continue to be so. At the grand old age of 79 my brother in law is not about to change his ways and is quite comfortable listening to his old Cassette collection whilst out and about, on trains quite a bit of the time, as he travels up and down the country. He’s a lovely old fashioned set in his ways guy and we wouldn’t have him any other way. It would be blooming lovely to get this back to him working again.
It’s scarred, been well used but looked after, apparently it’s gone from playing quite well, to slowing down and dying completely. I think I know what the issue is but I’m not going to curse myself by saying I know what is wrong, when it actually turns out to be something totally different.
On the Beach – Chris Rea
And I love his choice of music. Let’s get this repair underway so we can listen to Mr. Rea in a lovely crisp sounding manner befitting of an 80s rock star.
Repair:
Batteries in place, earphones connected, push play. No movement from the capstans, and even when put in forward and reverse there is no movement from either capstan. I can hear all the electrical noises such as the tape head picking, and I suspect at the grand old age of 32 years old that the drive belts have probably given in. Let’s open it up and have a look.
And just as I thought. Two drive belts in here, they are both loose, one though is so loose that it has wrapped itself around the two capstans, no wonder it wouldn’t start up.
Two drive belts visible, both so stretched that they have ceased working
I have plenty of these belts spare, I just had to sort out the two closest matching in size. Too slack and you introduce warble, too tight and it will be off speed, you need to get it just right. Adjustments can be made to the motor speed but this will only come back to bite you once the belts wear in.
New belts in placeOld slackened belts
I’ve put two new belts in place, and at some frequencies there is a little wobble, but with Dolby switched in place this can be removed digitally, this will settle over the coming weeks after more use.
I have used some silicon grease on the cogs, I have put contact spray in the motor and the volume controls, and used IPA to clean all the tape contacts and capstan wheels and posts, it’s basically been given a little service to see it forward for a while longer.
Body now reassembled, new batteries put in place, it’s time to test it.
Result:
A quick polish, to tidy up, won’t get rid of the deep scuffs, just makes it a little more presentable. Cassette inserted, headphones plugged in and as expected it’s working just fine, we can hear Mr.Rea in all his gravel voiced glory. So can you, in this video snippet below, that hopefully won’t get a copyright strike 🤞
🎶 On the beach 🎵
So there we have it. Another item brought back to life with about 30 minutes work. It’s going to make someone’s day, and I’m as pleased as punch that I could play a part in contributing to that.
Working well, looking ok after a quick service and some TLC
There you go. Hope you enjoyed this quick fix.
Many thanks for passing by. Always most appreciated.

The Finepix S2 Pro
I’ve purchased three cameras as a job lot in an auction. All of them have issues but the issues have not been clarified. This is very much a “Suck it and see” auction where I get what I’m given. I’ve paid £24:22GBP for all three and that includes free postage. I’ve purchased from this seller before who is a bonafide Camera business based in South Wales. He has no time for faulty items though, quick in and out is his way of working, no time to fix stuff. I’ve got three good cameras in this bundle and this works out at just about £8:00GBP per camera. And where can you get cameras like this for those prices nowadays.
I’ve just read a blog where a guy had one of these cameras from new, and in 2002 he had paid £1550.00GBP for this camera. Wow, and here i am 23 years later paying the grand total of £8:00GBP for one. Even if I don’t get it working, I’m happy with that.
Now this particular camera had two issues in its lifetime that caused concern, and one of them meant it was pretty much game over, and that one was the CCD issue that used to plague this range of cameras. Fuji released a whole bunch of these cameras with a faulty CCD that had to be fixed under a recall. They built sufficient replacement CCDs to cover the recall and that was about it. There were no remaining CCDs left and at that point what was left had become as rare as hens teeth. If you suddenly developed that faulty a later date, then tough…you were stuffed.
Serial numbers affecting CCD problems are listed below:
Model Serial Number Range
FinePix S2 Pro 31A127**~31A143**
32A000**~32A039**
33A000**~33A007**
34A000**~34A004**
Fujifilm
The second issue was with a batch of these models that had a “bad” resistor in the power circuit that prevented lock up if there was a power spike, if this failed then the camera just stopped and you were stuck. There was another recall on the second issue but there is probably a lot of cameras out there that again weren’t part of this recall. And I guess owners were pretty fed up of recalls at this point and were off loading their equipment as quick as they could.
The serial numbers regarding the lock up problem are listed below:
Between serial numbers 24L00441 and 24L00680 Between serial numbers 24L01057 and 24L01256 Between serial numbers 24L01553 and 24L01863 Between serial numbers 24L10257 and 24L10608

My camera serial number
Above you can see the serial number for my camera. Thankfully my number falls outside the range of any of the cameras inflicted with either problem, so it’s fair to say (Fingers crossed 🤞) that I shouldn’t suffer with any of the known issues with this unit. In layman’s terms I think i may well have dodged a bullet here.
I did speak to the seller regarding the fault on this camera and he stated it was just a general error code on the top screen. There is a general error that arises occasionally regarding certain lenses where they have to be locked on their minimum aperture for the camera to work properly, however I’ve not attached a lens yet so this cannot be confirmed.
Here’s some history:
The Fujifilm FinePix S2 Pro is an interchangeable lens digital single-lens reflex camera introduced in January 2002. It is based on a Nikon F80 (N80 in the U.S.) film camera body that was modified by Fujifilm to include its own proprietary image sensor and electronics. Because of the Nikon body, it has a Nikon AF lens mount and so can use most lenses made for Nikon 35 mm cameras. It is autofocusing, with an electronically controlled focal plane shutter with speeds from 30 sec. to 1/4000 sec., built-in exposure metering and pop-up flash. Its ISO film speed equivalents range from 100 – 1600. The S2 Pro also has sound recording capability. The camera is no longer in production, having been superseded by the Fujifilm FinePix S3 Pro in February 2004.
Aside from the Nikon lens mount, the camera’s principal distinction is its 6.17 megapixel photo sensor. Known as the Super CCD, it is unique in having its photodiodes oriented diagonally rather than horizontally and vertically as in all other DSLR cameras. This allows the use of a sophisticated interpolation system that produces an output image equivalent to 12.1 megapixels. The apparent resolution of images in this interpolated mode lies somewhere between 6.17 megapixels and the 12.1 megapixel interpolated output.
A huge number of these cameras were built using a Sony sourced defective CCD that was subject to a recall by Fuji. The recall ended when the stock of these replacement CCD’s was depleted. There is word that no other stockpiles exist of this Super HAD CCD, making these cameras that are found with the purple or black tinted image problems extinct, only usable for parts. The Fuji F700 used a similar defective HAD CCD, but in 3.1/6.2Mp size. That camera has met a similar fate.

So let’s hope that we can get some pictures out of this unit. We just have to wait and see what arrives.
Assessment:
Well the camera has now arrived, and I must say it is in an absolutely beautiful condition. Cosmetically there isn’t a scrape or scratch, all screens are scuff free and it looks as if this unit has been well cared for. It just needs a wipe over to clean. The package is just the camera body with no extras such as a body aperture cover or neck strap, but who’s worried about that, they can be procured at a later date.
Front viewRear viewFlash openNikon type F mount
These units are quite power hungry requiring a total of six batteries. 4 AA cells go in the base and two Lithium CR123A batteries go in the grip. These batteries work in unison, one set handling the basic camera functions whilst the other deals with the capture and processing of images. It’s a strange affair, loosely based around the same setup that was originally on their film based camera counterparts.
AA batteries CR123A batteries
I’ve had to order the lithium batteries, however I can still get displays and Information using just the AA batteries in the base, basically it is semi functional in this situation.
The lens mount is a standard Nikon F mount, I’m going to have to search through my equipment to see if I have such a lens, I suspect I don’t, so I may well have to purchase a small lens purely for test purposes. I have some other Nikon repairs in the queue, so a lens to have for test purposes wouldn’t really go amiss.
The unit takes either a CF card type II or a Smart-media card (Max size of 2Gb on both) that is located behind a hinged section on the rear of the camera, these work fine and have no bent pins.
Media card ports at the rear
With batteries in place I get the full range of menus, and nothing comes across as suspect at all at this stage in the assessment.
The top menu – no lens attached to test
The top menu by the exposure button is the only “F” indication showing, I have no lens attached so this might be the reasoning for that, but if I do put the menu into manual mode I get the full range of shutter speeds and can even operate the shutter, the shutter seems to be working at all selected speeds with no issues as far as I can see.
Some of the shutter speeds available in manual mode
All other menus are available and I’m even able to format the CF card via the cameras menu. The picture you see on the screen was taken on another camera. It wiped fine so no issues here.
Various menus and the screen after a format was completed through the cameras menu controls
The camera seems to be working with no apparent communication issues as yet. When you try to use the flash it even informs you that you need to insert the correct batteries to test. As I’m awaiting the CR123A batteries I won’t be able to test the flash functionality until they arrive.
No CR123A batteries installed? – You can’t use the flash
As I have stated the testing can only go so far until I have the missing items in my possession, for me that is the two missing batteries and a suitable lens. I’m currently in the process of procuring both. Physically there is nothing wrong with this camera after spending a good couple of hours going over it. I’m quite comfortable with it and believe it could be a lens communication error or just a failure to read the instructions properly by the previous owner. All I need now is that lens. I’ll let you know what occurs in the repair section.
Repair:
To be quite honest it’s not really been a repair, it’s been more of a “pre flight check” to collar a phrase, going through all of the cameras capabilities and ensuring that they are all functioning correctly. As the camera was listed as faulty, and the fault was not identified, I have had to do many hours of testing and Investigation to get to this point.
I’ve done a bit of shopping and managed to buy a nice little lens from the Southern hospice group. Always happy to help a charity and secured this at a good price of £15:50GBP, and that includes the postage, for a Sigma 28-200 f/3.8-5.6 Ø72 Zoom Lens Nikon F Mount. There looks like a bit of fungus on the outermost optic, however I can always clean this if it’s too bad. If not I’ll just leave as is for the moment and keep it vacuum bagged between uses, I can always do a separate post on cleaning up fungus in a lens at a later date. (I have done a basic fungus clean in the past : Canon EF lens 35-80mm)
My new – old test lens
I wasn’t looking at spending too much here, as I only wanted a lens to test a number of Nikon repairs I have upcoming as well as this S2 Pro. This lens will fit that role perfectly, and be added to my collection of other lenses that I have that allows me to test a range of different camera products. I have also purchased an “F” mount body cover for the camera to protect the unit when there isn’t a lens attached to it.
The two CR123A batteries have arrived and have been placed in the handle grip. The warning that was there before the batteries were installed (see picture above) has disappeared and when placed in manual mode the flash fires just perfectly, no issues here.
The Lens has arrived. Good point is that it fits fine and looks good, and all electrical contacts are good. Bad point is it has severe fungus throughout, and is just like looking through a fog.
Severe fungus in the lens
I will do a separate post on cleaning this problem up in a later post. However I’m not overly worried at this point, I paid a very low price so it was to be expected, I’m not complaining to the seller who was a Hospice, they need the money and I can fix it so there really is no problem.
That lovely looking lens hides a problem
The excellent news is that the lens does exactly what it should. The camera indications are good, all working exactly as expected . However the pictures via the screen are extremely hazy due to the fungus infection on the lens. There are no black or purple casts on the pictures so I am quite happy that we haven’t inherited the dreaded CCD issue discussed earlier in this post.
Hazy days – Lens fungus
If I use the lens wide open and pop the camera into auto mode I do get an “ERR33” code and that is a communication issue between the lens and the camera. As I have stated earlier in this post, you have to have the lens set at its lowest aperture and locked for the error code to go. Fortunately this lens allows you to lock the aperture and once this is done the camera takes over the exposure when it is working in automatic mode. So as I also stated earlier, it appears the seller was probably not aware of this requirement/issue.
Result:
We have a fantastic working camera, it does all it was produced to do, it has its little quirks and oddities, but being familiar with these cameras and at least having some knowledge and awareness of how they operate is always a wise thing. Read the instructions and don’t just throw them in the drawer until you eventually sell the camera on as a damaged item, when in fact you were just lacking the knowledge on how it operates in the first place. Instruction manuals are good, they serve a purpose. Knowledge is king.
The complete camera with lens
This camera cost me £8:00GBP. That is a superb price for a camera of this quality even though it is now 23 years old. It has a lot of life left in it, and I can’t wait to get it out and give it a real test.
It’s a little beauty – And the lens that needs attention
So in theory I’m confident and happy that this camera is now in a fully operational order, it’s needed a clean, it’s needed a lot of research to find out how it works, and I’ve also downloaded the operating instructions and repair pack should they be required.
It’s taking pictures and storing them. It’s just the lens at the moment isn’t performing at its best due to its fungus on the optics issue. I’m keeping the pictures stored on the card to compare them with the new pictures that will be taken once I have another lens to use.
Once the lens clean up is complete, if I ever get around to it, I will link it through this post.
Edit:
As 12/7/25 I have purchased a newer higher quality lens without any of the above issues to be able to get some instantaneous results, and as I have about seven other Nikon cameras requiring testing, some with sensor issues, it was wise to invest in a better quality lens. I have purchased a Nikon 28-100mm AF Zoom Nikkor Lens G AF-d, in perfect condition and the post regarding it can be found here: Nikon 28-100mm AF Zoom Nikkor Lens G AF-D
A newer – old lens, much superior quality
As previously stated I will add photos in this post once the new lens arrives, to show the difference from the fungus infected lens to a decent lens. The old lens is still a work in progress and I will post about it again as a separate post once the clean up is complete. It will probably be a job completed once the long winter nights are back in situ.
Below are comparison photos between the old lens with fungal issues and this new lens:
It’s just typical for me to manage to make another post from an issue that has arisen from fixing a different item. But isn’t that life? Continuous improvement is a factor we come across on an almost daily basis, and if you deal with old items as much as I do, then there is always something else that needs repairing, something that requires your attention and I just love that. The ability to improve or make something better, gives such a feeling of achievement and accomplishment, and total satisfaction. And that’s why I write this drivel. It’s for me, it’s what this blog was originally set up for. It’s my journal of what I do.
Many thanks for following this post. You know it is always very much appreciated.
This auction is for a used cased Sinclair Cambridge Memory pocket calculator and original case. The item is in very good cosmetic condition as is the case which still has its instruction sheet. The item is powered with 4 x AAA batteries (not supplied) and does work although 1 of the digits is faulty and does not display (see pictures) plus the number 5 digit is not working. Please refer to the pictures and description provided before bidding.
EBay
It’s faulty…obviously
So it does work, but it doesn’t? This calculator is a model one memory calculator, that dates from around July 1973, ( Actually May 1975 see photos below) and is one of the earliest available mass produced electronic calculators available in the UK at the time. And it was produced in collaboration with a guy called (Sir) Clive Sinclair, who in the following decade would become synonymous with tech development in the UK. It retailed at £29:95GBP, and given the rate of inflation, its cost today in 2025 would be a staggering £463GBP. Wow!
Courtesy of Vintagecalculators.com
I love collecting old calculators, I couldn’t afford one back in the day when they arrived on the scene as I was only a child and probably only on about 20 pence a week pocket money, and savings and investments were not even known to me at this period of my life. The thought of saving that precious 20p a week for the next 150 weeks wouldn’t have even remotely crossed my mind. What no sweeties?
But I can buy them now, so no big issue!
So this one has become available, and I’ve been tracking it for a week or so, there were nine other people watching but I secured it for a total including postage of £14:49GBP, and I’m happy with that, it’s a piece of retro history for a very good price. Even if it remains faulty, or should I say working but not working?
This unit obviously has its problems, the button number 5 doesn’t work and one of the led digits is also not functioning. Hopefully I can get these issues sorted and soon have the calculator back up and working as it should. That would be nice. I’m looking forward to this little project.
Assessment:
It’s arrived and it’s a lot smaller than I anticipated. It has a separate hard protective case, which is a nice touch and a small info sheet on its operation. Cosmetically it’s in a good condition with just minor signs that are age related. There are no gouges or scars so it has been treated well, though it’s not pristine.
Two buttons unresponsive and one LED
Batteries go in ok but, I believe old style AAA batteries were a little wider than those used today and would sit a bit more snuggly in the battery compartment. As you can see there is a little wriggle room here, and springs at both ends need adjusting to help prevent this. I may have to use some spacers so the batteries sit tighter in place.
Gaps between batteries – means movement
The switch is a bit temperamental and can be seen quite plainly from the battery compartment. It looks strangely out of place with no batteries in place.
Switch offSwitch on
It is such a basic design solely relying on tension of a small metal plate to short across the connection points. Should be a simple enough issue to sort.
There is a little battery contamination on one of the battery contacts, again this shouldn’t be too much of an issue and should clean up ok with some IPA.
Some battery contamination
It was originally reported that there was one unresponsive button this being the number “5”, there is also another unresponsive button, the multiplication “X” button. There is also one LED indicator, the 4th one in from the left hand side that is not operating. Add to this the issue with the On/Off switch and the contamination, and the original faults reported in the original sales pitch have now doubled. I just wish people would spend more time going over the issues and then give actual accurate feedback as to what the real faults are, it would make for a far more pleasant buying experience. Rant over.
There doesn’t seem to be a single screw holding the body together, I just hope it isn’t all heat welded.
Let’s try to get inside.
Repair:
Well it cracked open quite nicely with no issues with just a plastic flat prise tool. The main board just sat comfortably in the unit, secure, and not a screw in sight. Strange as time moves on some of the games units I come across have best part of fifty of the little blighters to remove before you get anywhere. sometimes the old way is good.
Bare boardOpposite side of boardDate is May 1975
The dismantling of the keyboard is a little complex and you have to take time and make sure you know how it’s going to go back together, it’s just a bit fiddly. The board is quite straightforward and as soon as I see some of the IC’s it dates the unit perfectly. The chips are dated May 1975, and that is about 18 months younger than what I originally thought, it’s quite informative to get inside and learn occasionally and this is just as good as having a birth certificate presented to you. All good stuff.
I’ve proved that there isn’t a problem with the missing digit on the display as using my multimeter in diode mode I am able to prove that this LED is working fine.
LED working
The picture shows just one part of the display range on this particular digit, I can assure you all other sections of the display are also working.
Regarding the case with the buttons not working. I have checked this out for continuity and both digits go through the same portion of the main IC and there doesn’t appear to be any broken traces. It’s a strange one but I have also found some really poor solder joints that are either cold joints or just poorly soldered from the start, there are a couple of resistors that need re soldering. It may be nothing at all, but it needs attention, a full reflow wouldn’t go amiss or take too much time.
Faulty resistor joint
I’ve reflowed the entire board due to there being a few cold solder joints.
Full reflow completed
On top of this I have taken off two old capacitors and tested them out of circuit, and both were out of their operable range of +/- 10%. As a result of this I have replaced the offending components with comparable new ones.
Old capacitorsNew capacitors
Even with all these extra tasks being undertaken there is absolutely no change in the way it operates. Nothing has gotten worse, the faults that were originally there still remain. I have done some research on line and carried out some further tests and checked expected voltages, most are within range except one that appears to be less than its expected value. After testing everything on this board, every component I can only surmise that one of the three chips has failed, I suspect very much that this, the main chip, a CZL550 integrated circuit. Otherwise known as “Calculator on a chip” is the one that is at fault.
A CZL550 chip
To be quite honest these chips are fairly rare and command a price far in excess of what I paid for the original unit, and I don’t really want to do that. I think I’ll wait around to see if I can secure another faulty unit to complete this repair, so in the meantime, and until I can secure such a unit I will put this repair on hold.
Result:
Well, it’s not what I wanted but sometimes you just can’t win with some of these old projects. In no way am I walking away from it, it’s just that the parts are so difficult to get hold of that you really do have to just wait until a sufficiently faulty one comes up for sale. And that could be days, it could be weeks or months. So for now i admit defeat, but it will not be going to trash. It will remain in my ever expanding “To do” box, for me to pick up on at a later date. And when I am in a position to move this project on, I’ll pick it up in a continuation of this post.
Many thanks for passing by. It’s always appreciated.

Finepix S9500
I’ve purchased three cameras as a job lot in an auction. All of them have issues but the issues have not been clarified. This is very much a “Suck it and see” auction where I get what I’m given. I’ve paid £24:22GBP for all three and that includes free postage. I’ve purchased from this seller before who is a bonafide Camera business based in South Wales.

And where can you get cameras like this for those prices nowadays.
I really don’t know what the specific issue is with this camera only that it is faulty. I guess we will just have to wait it’s arrival for a full assessment. In the meantime here is a little bit about it.
Fujifilm FinePix S9500 or FinePix S9000 is a bridge digital camera released by Fujifilm in 2005 and intended for the enthusiastic amateur. It is a member of the Fujifilm FinePix family and has been superseded by the Fujifilm FinePixS100fs. It has a long list of advanced prosumer features, like combining having wide-angle ability (28 mm equivalent on a 35 mm camera), full range of manual settings, mechanical zoom ring, high ISO-sensitivities, and some of the versatile features of Live-Preview Digital cameras (LPDs) like movie mode, movable LCD panel, and macro mode.
Wikipedia
Assessment:
Wow. Another camera in a fantastic condition as part of this damaged package of three. And I owned one of these when they first came out in 2005.
Working fine Flash worksAll menus okScreen and extension fine
I really had to look hard to find the issue with this camera, I have checked every menu, mode and function and it is working absolutely perfectly. Then I found the issue when removing the battery.
Loose battery contact under battery door
Unbelievable, the only issue with this camera is a loose battery contact plate under the battery door. These are normally sealed with moulded plastic, but it looks as if this one has come adrift. It just needs fixing back in place, I can’t believe this is all that is wrong with this camera. Apart from needing a little clean.
Another bonus
And an added bonus with this camera was that it came with a 2Gb CF card. This just so happens to be the biggest drive size these cameras take. You can also use TF cards. Again, this was a very welcome bonus.
Repair:
Probably the simplest of repairs you’ll probably see. I really apologise for this being a bit of an anticlimax to anyone wanting to see a technical repair, because you won’t be seeing one. But just sit and think it over for a moment, that someone was prepared to dispose of this perfectly working camera as it was not working in their eyes. We really are a throwaway society. And then there are simple people like me who love these items. And we fix them.
A hot soldering ironPlastic re-welded
All it took was a hot soldering iron and a pair of tweezers. The metal plate was held down and what remained of the broken plastic welds protruded above the plate. Using the hot iron the welds were melted back to secure the plate in place as it had been when it left the factory. There you go. Job done. Simple.
Result:
For £8:00 I have brought myself a little bargain here. Ok it’s 20 years old now, works perfectly and does what it was built for. Capturing history, your personal history, both good and bad and creating moments for you to treasure forever.
All cleaned and looking beautiful
It doesn’t matter what the megapixels are or any of that chuff the “purists” insist you must have in a camera, just push the button and treasure the output for the rest of your days. These cameras are the ones we should be carrying for fun, to learn about photography, the cameras the kids should have now that we had 20 years back, they still have that life in them and the ability to teach and encourage a younger generation to get into photography. And before you say they have phones, that’s not the same. They’ll learn more from one of these on a phone free afternoon, then they ever will by being interrupted by “Soshul Meeja” all day.
Get out there, get your kids recording their world. They’ll thank you one day.
And yes it works well, the Camera is in cracking order and only missing a strap and maybe a lens cap that I may procure later down the line.
The good thing is that it has been saved from disposal, and has years of good honest life left in it.
Thanks for passing by, you know it’s always appreciated.
Simple as that. And yes it’s a tiny radio but in excellent condition cosmetically.
Bush handheld
On inspection it’s obvious that the micro USB port is damaged and will need replacing.
Broken micro USBWhat’s wrong?Power board
I’ve ordered some replacements USB ports from our friends in China so I’ll have to wait a few weeks before I can progress this project any further.
Micro usb ports
The ports have arrived from China, so let’s look to see if we can repair this unit.
*This project has been on the back burner since May 2024. 13 months later and I’m now on it*
Hello all, time to clear that backlog and what better place to start than here. I do in fact have two of these with the same problem so this is a two for the price of one project.
This should be a simple case of replacing the faulty charging ports that are both micro usb ports. They are small believe me.
Old port removedNew port that has to be fitted
There has to be some preparation before we can get the new port on. Using a soldering iron and flux and a little solder wick, I clean the old board remove the old solder and give a good clean with IPA. I then prime the small connections on the rear of the charge port with a little solder. Now I put the port to the board and tack on the earth points. Then using a rework hot air gun I blast the port at about 350 degrees Celsius and hold the port in place with some tweezers until I see the solder glisten and melt around the port. I take the heat off and let the solder set before moving the tweezers and when it’s cooled a bit I check that it’s setting straight, all connections are good and solid. I then just add a tiny bit more solder to the anchor points for strength.
Whilst this is cooling down I check the status of the battery. It is a 3.7v rated battery and is currently holding a charge of 2.8v. It’s a little low but far from being dead. The second battery shows a similar charge.
Battery level
After the solder work has cooled I use my battery pack connected to a small ammeter to see if the radio and more importantly the battery is demanding any power.
Power cable connectedWe have a power demand from the battery.
Well that’s good news, 5v in and the demand from the battery is 0.96 of an amp. The battery is charging. And the fix is as simple as that.
Two perfectly good radios
A little bit of soldering aerial contacts and a couple of other wires back into place and the whole unit clicks back together. Two screws inserted in the rear and time to switch on. Both radios tune in perfectly and the sound is surprisingly good for these little units. I’m keeping one in my work space at home, as I love having some music around me, I’d sooner listen to the radio any day as I hardly watch TV. The other radio will go into my work locker for when I’m working nights or in the workshop.
In my work space, but it won’t be staying here…
Im very happy with this little project, it only took about an hour and I don’t know why I left it so long. Another couple of items saved from the tip, it amazes me that these units probably all suffered with the same problem of inferior parts that failed early on in the radios existence. Kind of scares me just how many did go to landfill.
Two cracking little radios
Well at least these two are going to carry on for a few more years yet. And that’s a positive in my eyes.
Fujifilm Instax 100 Instant Film Camera – Faulty Untested See Lens Shutter

Instax 100 Instant film camera
I’m a tad annoyed at myself here as I had arranged a good price with the seller but because I was too eager I pushed the wrong button and purchased at the original advertised price. The seller must think I am a right plum, and I’d be inclined to agree with him. That said I’ve secured this for a good all in price, and it will be a nice addition to my collection. It’s a 26 year old camera, and i’ve been looking for one of these particular cameras that use the wider format of Instax film for quite a while, but even the damaged ones command hefty prices. I’ve paid an all in price of £28:55GBP here when I should have paid £23:55GBP. Never mind, lesson learned and don’t be so hasty in the future. They can command a good price as can be seen in the photo below:
Some recent sale prices
Here’s some info about this camera:
The Fujifilm Instax 100 was released on May 1st, 1999. It has been replaced by the newer Instax 200, which is very similar except the flash is on one side rather than directly above the lens.
Focusing: Motor-driven 2-range switching (0.9 to 3m/3m to infinity)
Power supply: 4 LR6/AA-size 1.5V alkaline batteries for around 10 film packs.
Dimensions: 171.5 x 91.5 x 119.5 mm
Weight: 650 gr (without batteries, strap and film pack).
Camera-wiki.org
Now this one is being sold with what looks like only one fault that the seller is concerned with and that being a shutter problem. From experience and as can be seen in this recent post of mine: Another Fujifilm Instax mini 8 I know that this is not a “Lens” issue it is in fact an issue with the iris that protects the lens, and is probably as a result of a small spring being disturbed in that area. It’s quite a simple fix and if it is the only fault then that would be quite some result. However, this is EBay that we are talking about and there could be a number of further faults we haven’t been informed of. Now I will just have to be patient until it arrives, there is no other choice.
Assessment:
It’s a big one. Compared to the other Instax mini cameras this one is very big. It’s probably 1.5 times bigger than your standard SLR. It’s big. And weighty!
It’s clean…ish. And there seems to be a strip of plastic, a gate as such missing from the top of the camera near the exit slot. This wasn’t mentioned and I’m quite annoyed about that. When batteries are put inside it makes all the noises, but the action isn’t smooth in the lens extension range. This probably ties in with the advertised issue of the lens iris operation. I’m thinking I paid well over the odds for this particular camera, I’ve been conned here, lesson learned.
There could well be multiple problems here, and if that missing piece on the top is anything to do with light proofing, then we could have an issue. Anyway we will cross that bridge when we come to it. Initially I’m going to stick with the original fault, so let’s attack that and worry about any other issues if and when they crop up.
Repair:
The more I get into this camera the more I find wrong with it. The main issue of the faulty lens iris is a fiddly one. You prise off the last section of the lens turret and the iris mechanism comes away fairly easy.
Mechanism removed from lens turret3 tiny springs all disconnected from the mechanism
But then three tiny springs just fall out and this is why the iris didn’t work. Trying to get them in place is a puzzle itself, as no sooner do you have one connected then another drops off. It’s a fine balancing act to get them all back into place. When they are all reconnected it’s a very delicate operation to get them back into place. And even then you have to go to the inside of the camera to ensure that the lever inside that operates the iris, is aligned to the iris mechanism that is being installed back in the lens turret. It’s a fiddly time consuming job.
All springs attachedThe lever on the inside that has to be in the correct position when the iris is attached
Iris now working
At this point the rear fascia and associated ribbon cable need to be removed to facilitate this repair. That’s when a piece of broken plastic falls out, it just so happens that one of the posts putting tension on the print rollers has broken. Great. Another problem. I’ve quickly fixed this by using some wire to act as a retention point. Bodge? Yes, but there really is nothing else that can be done here as the plastic case is thin and brittle. I have used some silicone grease to lubricate the cogs and the whole movement is now a lot smoother. It Will work. of that I am confident.
Broken plastic post, spring out.Wire bodge, spring now back giving tension
Result:
Well it works but it remains one of my most disappointing fixes due to the dishonesty of the seller. I know, if you buy off auctions it’s Caveat Emptor as they say, I preach it enough but this time I was caught off guard. Lesson learned. But I remain disappointed. Multiple faults, sold as just the one when in fact it also had bits missing that were not declared, very misleading in my opinion. Maybe in future I need to look deeply into these purchases before I give any feedback, i need to change my operation as I was truly shafted here.
Polishes up nice
It does everything that it should, the motor and transport system work, the iris now works, shutter is good, and flash operates. I’m confident that the camera is working fine but I haven’t tried any film through it yet as it uses a bigger format film and is quite expensive, and I’m not forking out for any just yet. Maybe when I get another wider format model to look at I will pay out. Just not yet though. When I do get some film through it I will amend this post accordingly.
I’m off to calm down a bit now, thanks for passing by, I really do appreciate it. Have a great day.

The Instax mini 40
Now that’s what I call a great descriptive sales pitch. And that’s because the guy is a professional seller of photographic equipment. I’ve seen the video he posted and all the above is true, it really is just a problem around the flash. Maybe it’s an easy fix? I suspect not but either way it will be an interesting project.
Here’s a little info on this camera:
Hitting the market in April 2021, the Fujifilm Instax Mini 40 takes the updates the Fujifilm Instax Mini 11 introduced but wraps them up in a cooler, more retro-styled instant camera body. Instant film fans will probably love it and with its improved design, there’s a chance that those who aren’t instantly drawn to this form of photography may just want to have a play around with the Fujifilm Instax Mini 40, too. It does cost more than the Fujifilm Instax Mini 11, though, so you’ll have to decide if the cooler design is worth an extra £20.
+ Pros
It’s fun
Great party camera
Easy to use
Looks cool
– Cons
Film is expensive
Viewfinder could be better

I first of all went in with a cheeky bid of £15:00GBP that the seller originally turned down, so I then put in a high bid of £18:00 and as no one else was wanting it, it actually sold for £16:00, just £1:00 more than I’d originally offered. All in all the cost with the postage was £19:45GBP and I’m really pleased with this. Im surprised though that there are flash issues in a unit that is only just four years old. As you can see in the photo below recent sale prices have been strong and a great deal higher priced than what I have just paid. These are certainly popular little camera’s with the younger generation.
Recent sale prices have been strong
I guess we will just have to await its arrival to assess the flash issue. I’m very confident that I will be able to get this camera up and running again.
Assessment:
Out of all the Instax cameras I have dealt with lately, this has got to be one of the best ones I have had my hands on. This is a mid range instax camera that is more sober in colour aimed at those who enjoy their lomography or better quality instant photography. It certainly looks good, and to be honest I’d rather carry this one around rather than a bright pink one.
Looking nice and sober
As posted in the description above it is in near perfect condition and a quick Look at the flash head shows that the flash bar within the unit is broken.
Flash bar brokenConfirmed broken when removed
Let’s get on with replacing this damaged flash unit.
Repair:
Let’s get it opened up.
Dismantling
People laugh at me when i tell them that playing around inside these units could kill you. I can understand the contempt aimed at me for such a statement, when I’m carrying a bright pink camera that hardly looks dangerous. Just look at the voltage still in the flash capacitor though once I have opened it. Savage.
Residual voltage of 267v still in the flash capacitor
270v would quite easily send you across the room, if you had a heart condition it would probably be game over. I’ve learned my lesson in the past so I ensure I use a capacitor bleed probe before I go anywhere near one of these flash capacitors. The capacitor on this camera is rated at 320v, not to be messed with. Beware. What’s more impressive is that all this energy is supplied from two 1.5v AA batteries. Clever stuff.
I have a donor flash bar in an old spare unit. I have carefully unsoldered its connections and gently removed the very thin glass tube from the donor unit and placed this in the one situated on the new camera.
The donor unitIn place and soldered onto the board of the repaired camera
Carefully, once inserted into the flash reflector, i have soldered it back onto the board. All looking good. However I need to test the flash so I temporarily put the case on, bung in two batteries and turn the camera on. Press the exposure button and the flash fires perfectly. Happy days. I now can confidently reassemble the camera back together, and I’m pleased that when this is done there are no screws left over. All small wins.
I have some film available so there is no better time than the present to give it a try.
Result:
Nice flash – working Working perfectly
I’ve loved doing this repair, this is a good quality, great condition, and now in perfect working order camera, brought back to life with many more years of use left in it.
But it could have been just chucked in the waste. I’m keeping this one for my collection as it’s a fantastic example acquired at a very good price. Thirty minutes of attention is all it took.
I’ve just purchased three of these cameras for a total of £24:98GBP. All non working of course but when healthy they normally command a price around £35:00GBP each. Here is what the listing said for each one:

It has two faults
The springs on the back are broken, meaning the rear metal plate is bent , and it often doesn’t push photo paper through correctly.
The shutter button is also depressed.
EBay
This third one might be a longer term repair as I’ve never known a quick fix for a depressed button, that requires a psychiatrist… (That’s me just trying to be humorous, I’ll grab my coat and leave now 😂🤦♂️)
To be honest the issue with the third camera seems to be a regular problem based around the design of this camera. Too much pressure on the button normally results in the switch inside detaching from the main board, it’s poorly positioned at an angle and usually not soldered in place too well. The springs should be an easy fix.
I’ve brought these cameras from three different sellers. if I’m lucky I’ll be able to get all three up and running, worst case scenario is that I use one for spares and have two good working examples.
Anyway I’ll just have to wait for their arrival to assess them all, and decide what repairs are required. In the meantime here’s a little bit about these cameras that are again very similar to the Polaroid “Snap” camera range, that also use zink paper. And seeing what is quoted below, the Polaroid “Snap” and this Kodak Printomatic are in all aspects one and the same camera.
Well, since Kodak doesn’t really make its own consumer cameras anymore, the Printomatic is actually being produced by a company called C+A Global, which is just licensing the Kodak name and branding. C+A also licenses Polaroid, and was behind the two-year-old Snap. Both cameras were designed by Silicon Valley firm Ammunition Group, which confirmed to The Verge that the Printomatic is basically the same camera as the Snap, though simplified and rebadged. (The cherry on top of this corporate synergy sundae is that C+A also works with Zink.)
Released 2017
The PRINTOMATIC camera instantly and automatically prints high-quality, full color photos with point-and-shoot ease. It uses KODAK ZINK Photo Paper, so no ink cartridges or toners are needed. The photo prints are durable, water resistant, and adhesive backed for extra fun. The camera’s speed allows you to shoot a new photo while printing the previous shot. The KODAK PRINTOMATIC is fast, fun, and easy to use.

Kodak Ltd & The Verge
The reviews all vary, from very good to downright diabolical, I’m not really surprised since Kodak “Hoared” out its brand name to the lowest bidder many years ago. Am I bitter? A little, as I used to work for Kodak in the days when they were a world leader, the mistakes they made, the decisions and leadership were absolutely awful. And the fact that their demise has lowered my pension pot by about 40% due to their financial mismanagement is another axe that I regularly grind. Yes I am bitter, and since I’ve recently repaired and reviewed their competitors cameras I thought I’d give these a try. Will I be impressed or disappointed? Who knows but I do have an inkling on which way this may swing. But for what I’ve paid for three cameras I’m not really that fussed, it’s just pocket money.
Assessment:
Camera one:
Apparently doesn’t print. Well I’ve put a couple of sheets of Zink paper inside and two pictures were produced. The sd card slot is fine, the charging port is in good condition. Transport is working perfectly. It certainly does print. Just needs a bit of a clean. To be totally honest there is nothing wrong with this camera and for an outlay of £8:00GBP in total I have a working bargain. Kerching – a rare EBay win.
Printer works, camera works
Charges fine Looking nice after a light clean – no marking
Nothing more to do on this one. So on to camera two.
Camera two:
It’s a bit grubby cosmetically but nothing that a light clean wouldn’t sort. This particular one cost £8:99GBP all in. It was dead on arrival so I’ve checked that the charging port was ok, and then put it straight on charge.
On charge
I’ve also given it a light clean whilst charging and the overall appearance has greatly improved. I must just be patient and wait and see if the unit does take a charge, or the original fault appears.
Initial red indicationNow a rapid flashing white indication
Whilst on charge the originally mentioned fault appears. The charging light was showing a steady red, it is now a rapidly flashing white light with the occasional steady red indication for all of a few seconds and then it’s back to the rapid white indication and it then all repeats. I’ll leave it for a while to see if there is an improvement, the battery just might be so dead that the inbuilt battery management system may just well be refusing to cooperate.the on/off button on the front doesn’t work as well, this might be also related to the battery issue.
Camera three:
Looking very nice and cosmetically very clean.
Nice camera
This one cost £7:99GBP all in. This one is reported to have two issues, a damaged paper pressure pad and a button stuck in the depressed position.
Paper pressure pad is bent and missing two springs Exposure button stuck in, white light flashing as a result
But first I’ve put it on charge to see that it charges, I’m pleased to report that everything is alright in that aspect, and I’m pleased to say it charged fully with the correct lights illuminated. The white light on the top by the exposure button is flashing as a result of the button being stuck in the depressed position, I believe.
Camera has charged fine
This one will need the paper pressure pad repairing as well as the button that is stuck in the depressed position.
Repair:
Camera one:
See above. No repair required. Just a light clean and some TLC. Why did they sell it as damaged? Who knows just what goes on, in the mind of an EBay seller.
Camera two:
This will need to be opened to get near the battery. We may well be able to get the battery to accept a small charge and this may be just enough to fool the battery management system in the camera to take over and continue charging.
Cover off and the confusing lights
Cover off I’ve checked the battery readings and it’s reading a healthy 6.5v and as it’s a 7.5v rated battery I believe this to be healthy, it holds a steady charge the battery is fine. Looking at the led lights they are capable of two indications, red or white and that’s it. I believe the charging light flashes when it’s charged as it cannot possibly show a green light as there isn’t one. This is confusing as normally a flashing white/red light normally indicates that the battery needs charging. Everything that is happening goes against what the producer has published regarding the led indications. But I am convinced the battery is good despite it not turning on. Hold on, I think I’ve found out the problem here…..
Cable disconnectedCable now connected On off button ribbon connector was not in place
It appears that someone has been here before me or that the on/off button ribbon connector has disconnected itself over time. Either way it’s not where it should be. I’ve put the connector back in place and secured it. I now have power and control of the camera.
All lights working, transport whirring away let’s put some paper in to give it a try.
PrintingDirty print roller
Well it prints ok, all pictures appear to have a “blue tint” to them, however there are big tramlines across the print as you can see, this indicates a dirty roller. What I’m going to do here is peel half the backing of a sheet of Zink paper as the back is adhesive allowing you to stick photos on whatever takes your fancy. By running a half sheet of exposed adhesive, upside down through the camera with the adhesive being the trailing edge, it should allow any debris and dirt to be collected on its way through. I will do this three or four times and even though I will no doubt get error lights appear I can just reset the camera with no further issues.
Zink adhesive exposed
And that worked. The tramlines have gone.
Tramlines on bottom left picture as a reference. All other pictures now clear.
I’ve also tried the black and white mode as you can see above. I’m very confident, in fact I am positive this camera is now working as it should. I have also put an sd card in the base and all pictures are being recorded as expected. A quick clean and we now have a perfectly good working example of this camera. Let’s move on to camera three.
Camera three:
We have to open up the camera to get to the issue with the button.
The paper pressure pad needs to be dismantled, straightened up and two compatible springs need to be found to keep the required pressure in place on the paper pad. I’ve dismantled the pressure pad and straightened it out, just needs a couple of springs to complete, I’ll sort these out later.
Bent upStraightened out Back in place just awaiting new springs
On opening the camera it was as clear as day that the depressed button was as I first thought, the three solder points below it had come loose, no longer making contact.
The working switchThe faulty switch that looks like it’s smiling
It’s plain to see in the pictures above that the button that is damaged has all three points of contact broken. these need re soldering to strengthen them. You can see this issue in the microscope pictures I took below.
Top: Before, Bottom: after
The switch has been tested and it clicks and operates as expected, this is a known weak point with these cameras and a design fault as well, although the manufacturer would probably deny this. It’s a given fact that the manufacturer wants to sell as many as these units cheaply to the throw away consumer, you only have to look at the main board below to see this…
Says it all really….
It really saddens me to see the levels the Kodak name has sunk to, these units are just replicas of the Polaroid touch/snap range, but even at this stage in the repair the Polaroid versions are far superior. Quality control and the cheap design of these Kodak units is borderline awful.
This unit is proving to be a right pain in the ass. The original fault with the exposure button has been repaired and the paper pressure pad is all but repaired, but it seems that being hidden by these two faults is a totally different issue. I have had this camera completely dismantled and have also separated the printer from the motherboard, but this issue of the permanently flashing white light still exists, so the fault is definitely only being carried on the motherboard.
Motherboard under microscope Lens ribbon cable insecureMotherboard separated from printer unit
I’ve checked the motherboard thoroughly using my microscope and there is nothing glaringly obvious at fault. I have checked for shorts on the board of which there are none. The only issue I found was that the lens ribbon cable was sitting off centre, however I corrected this but the flashing light issue still remains.
There are two faults that are connected with this flashing white light. One is that the light occurs whilst printing, this is not the case with this unit as it even occurs as stated with the printer disconnected. The other possibility is that it flashes when doing a firmware update, I have attempted to update with the latest firmware and the only difference is that I cannot turn the lights or camera off at all, I have to crash it by removing the battery.
It’s looking as if this could be the issue. The previous owner has probably bricked the unit by interrupting a firmware update and it has corrupted the system. I’m going to have one more attempt at updating the camera with a clean unused sd card to see if there is any possibility of recovery. If this cannot be done then this unit will become a spares unit that to be honest I’d rather not have as I don’t really want to purchase any more of these cameras. But you never know, someone may want one repairing.
Result:
Well in the wise old words of Meatloaf, I guess “Two out of three ain’t bad”. The grey one is bricked, as after numerous attempts of updating the firmware it just isn’t having it. It is just a brick. However there are numerous spare parts that can be used including a good battery, lens mechanism and a number of other pieces. I just didn’t want that though as i don’t really see myself going out of the way to obtain another one, they are as cheap and nasty as you could possibly find. The Polaroid versions are of a far better quality in my opinion, and they are hardly high class.
2 out of 3 ain’t bad
The positive here is that 3 cameras, quite obviously built for the throwaway generation have been saved from landfill and can be used again. What I’m going to do with the two I have is probably put them both back on to eBay to recover my out goings. If not, I will pass them onto our local hospice to sell on.
Been an interesting fix, but I’m not venturing back to these Kodak models anytime soon.
Remember this? Everyone had one around 1978 apart from me that is. Well, now I’ve got one, only 47 yrs late and it doesn’t work. But hey that’s what this site is all about, and that’s how I roll. Always late to the party, and even then you’ll probably find me in the kitchen 🥳
What the listing said:
Cosmetically in very good condition but does not work. Please see attached pictures to judge condition for yourself.

Another one with all battery covers! I’m shocked. And what’s that screwdriver there for?
The guy was after £17:00GBP and that included postage, but I put in a cheeky bid and managed to get it with postage for £9:80GBP. Anything under a tenner is good in my eyes.
Here’s some history:
Simon is an electronic game of short-term memory skill invented by Ralph H. Baer and Howard J. Morrison, working for toy design firm Marvin Glass and Associates, with software programming by Lenny Cope. The device creates a series of tones and lights and requires a user to repeat the sequence. If the user succeeds, the series becomes progressively longer and more complex. Once the user fails or the time limit runs out, the game is over. The original version was manufactured and distributed by Milton Bradley and later by Hasbro after it took over Milton Bradley. Much of the assembly language code was written by Charles Kapps, who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.

From what i can see in the pictures the item seems good, cosmetically. I may be able to see just a little contamination around the battery contacts but I can’t be sure. It worries me when i see a picture that shows a screwdriver alongside the item you are buying, it just screams at me that the seller has been in side and is not being truly honest about its issues. Let’s just wait until it arrives to do a full assessment. I’m genuinely excited about getting this working, as my age veers ever closer to the higher numbers. I need something to stimulate my mind, what’s left of it. 😂
Assessment:
The unit has arrived and on first impressions looks clean and tidy cosmetically. The pads are not very responsive and the battery contacts are seriously corroded. The unit is a power hungry beast, taking two ”D” cell 1.5v batteries and one PP9 9v battery. The unit does not work with its batteries in place, and i’m not surprised really, and to round it all off two screws are missing from the case, and one screw mount is broken. All four plastic springs that sit under the coloured pads are broken, and just to clarify someone has already been in here and it doesn’t bode well. My previous concerns of a screwdriver being in the original photos have been confirmed. It’s been tampered with.
Broken screw mounts and contamination Bad contacts – contaminated Pads unresponsive due to broken plastic spring mounts
The board is a typical of many circuit boards from this era that were produced for MB. I had a similar circuit board on this item here: MB – Computer Battleship
Top of boardUnderneath the boardYou can see the board structure that is typical for this era. The contact points are indicated by the red arrow marks.
In the picture above you will see two arrowed points. These points are the power contacts that make contact with the two seriously corroded battery contacts you can also see above. No wonder there is no power getting to the board. I suspect this might be the cause of our electrical problem.
Repair:
First thing to do is to get those battery contacts cleaned, as well as having a good clean of the main board. This has now been done. I’ve repaired the broken screw post by simply using a rubber washer that has been sufficient for this repair.
Contacts before and after
A friend of mine has kindly offered to print me off four of the “Double Y” springs to replace the ones that are already in place and broken. He owes me a favour or three and needs some subject matter to run through his new 3D printer so I’m very pleased to help him, as pending the outcome I may well buy one myself, as I have been threatening to do so for a while now. This should sort out the issue of the unresponsive pads, first found in the assessment of the item. He’s panicking that they might not be smooth and beautiful, I’ve told him not to worry as they are hidden inside anyway.
What I currently have on the left, what I’m expecting on the right
He’s just supplied me with five double “Y” pieces just in case one is damaged in some way. Let’s get these put in place to see the difference these make.
Out with the oldIn with the new
With the new springs in place the pads are working as they were originally designed to, now with some springiness in their operation. The battery contacts have now also been put back in place.
Cleaned contacts back in place
When assembled, the buttons are a little erratic and not always responsive so I decide to look into this further. A quick Look at the board shows that the solder contacts on the board for all of the button connections are worn, the solder has failed so I decide to reflow all these solder joints to improve the contacts. This appears to have worked as the unit when reassembled, now has uninterrupted operation. This is an age related issue. A simple fix.
Old solder joints that have failed and needed re-flowing
Result:
Another 47 year old saved from the scrap heap, it’s been an interesting and sometimes confusing repair and I thank my friend who stepped in to save the day by utilising his 3D printer to make some parts. Without his assistance this repair would not have been achievable.
Looking smart after a quick clean
It’s just another old piece of retro history to add to my ever growing collection and much to my wife’s dismay. Bless her.
Now working
Thanks for passing by, as always it’s very much appreciated.
Today 16th June 2025 and this boat that I was gifted for my last Birthday back in Nov 2024, finally underwent proper trials on water, and thankfully after all the issues experienced during the building process it came through them with flying colours. There are a few little tweaks to do as a result of the maiden voyage, but this will only go towards making it a far better and less stressful task on future excursions. Boy was i nervy about today, what with all my family watching.

I only have the one battery for the boat so time was limited, and I probably managed about 15 minutes with it nutting about, before it stopped and had to be rescued by my Brother in laws boat that just happens to be a tug, a seaborne version of the RAC.
Luckily the seaborne version of the RAC were on hand
Anyway prior to that minor mishap the boat performed quite well, the motor is hellishly powerful and I thought it would go either of two ways. Either it would launch itself out of the water like a missile or it would go nose first into a deep dive towards the bottom of the lake. Luckily it did neither, however I did learn that turning at speed is liable to capsize the boat, so care needed to be taken when performing turns under power.
And she works…..
As usual I have learned a lot. It needs some minor tweaks such as a better centralisation of the radio gear in the hull, it needs some Baffles to be put in around the front deck where the hull and the superstructure join, to prevent water ingress at speed. The front does sit low in the water but at speed the contours on the hull do create lift, and this does work very well, so I am particularly happy with this.
A great day out, at the start of the holiday, and the fact I didn’t have to go wading to rescue a failed boat is also an added bonus. Really looking forward to showing the videos and pictures to the elderly friend who purchased this fantastic gift for me. They will be as pleased as punch, as they know about all the hard work and care that has gone into getting this project finished.
Thanks for following the journey with this project. As always it is very much appreciated.
