Tomy / Palitoy Missile strike

Here’s what the listing stated:

This is a nice example of a Tomy ‘Missile Strike’ electro/ mechanical handheld game. It was made circa 1979 and is battery operated. It appears clean for age and works, apart from the missile light not illuminating. Battery terminals very good. This is a nice genuine item that is shown as I found it. NOTE – NO BATTERIES ARE ENCLOSED.  Nice example for any collector. 

EBay

Missile strike

On first seeing the listing for this item, my thoughts are that it looks quite clean and tidy. The usual state of these units are quite tatty with scratched screens. This looks good, however pictures, especially from EBay can be greatly misleading so I’ll guess I will just have to be patient and wait.

This units only issue seems to be with the LED missile light, so hopefully it will be a quick fix. These units are currently selling between £52-£79GBP as per the picture below. I managed to secure my unit for a total including postage of £24GBP so I think I’ve done well in that aspect. I’m quite happy with this.

Current sale prices on EBay

A little history:

Tomy released Missile strike in 1979 in its international line of electro/mechanical handheld games. Known under different titles in other regions such as Terra-Hit (UK), Missile Strike (UK), and Space Attack (Japan).  One of TOMY’s electro-mechanical handheld games, Missile strike is a Space Invaders-like shooter game, the units small motor winds strips of aircraft across the screen, which the player attempts to hit in order to earn points. There is a mechanical wind up timer that controls the action, and the purpose is to score as many hits on aircraft as possible with in the time it takes the winder to stop. The game includes one small, flashing LED light as the exploding missile.

So it’s another game that has reached its 46th year, and for the only issue to be its one light source, I think that’s acceptable. Let’s wait to see what arrives.

Assessment:

On arrival the first thing that hits you is that this is yet another filthy item. I seem to attract these kind of sales, so it will require a deep clean. Cosmetically the game is in good shape with no deep scarring and only minimal fine scratches on the screen lens commensurate with its 46 year old age.

Tidy cosmetically but filthy

It was sold as the missile light not working, this is partially right as it is an intermittent fault, I suspect this is down to dirty contacts.

Filthy, and counter not working
Missile light is intermittent

This game has two bands of film that run across the top of the screen displaying aircraft, the top band is intermittent and needs attention. The score counter will also need attention as it is not turning smoothly, again I suspect this to be as a result of the build up of dirt.

Repair:

First thing to do is dismantle the unit and to get some cleaning done. The small video below shows the issue with the top band aircraft not moving.

Film transport fault

I’ve taken the counter out after removing the case and all exposed buttons and switches.

Dismantling

Off to the kitchen sink. let’s get these items washed.

To be cleaned
Getting washed
Drying down

Whilst I’m waiting for the washed items to dry I clean the counter mechanism of old dirt and fluff.

Counter mechanism cleaned, fluff removed. Silicon grease applied

I’ve slightly greased the counter with silicon grease and it’s behaving well and doing what it should. This will go back in place when we do the final reassembly.

The issue with the film movement was a strange one. There was no way to tension the two capstans that the film roll over and there were no teeth missing off the capstans. One capstan pulls whilst the other pushes, all I’ve done is swap these around and the issue has disappeared. About as simple a fix as you can get.

Just swapped the capstans around

I’ve put a little before and after video here that shows the effect of swapping the capstans around.

How swapping capstans worked

The issue with the intermittent light was easy as expected. This is the only electrical piece on this game and it was down to contaminated battery contacts that just needed a bit of a clean with my grinding pen and a wipe over with IPA.

Final little touch was just to accentuate some of the old lettering by the timer. This was just with a white paint pen.

Before and after

Now we can reassemble and test again.

Result:

The game has been reassembled and tested and is now working fine. All intermittent issues have gone and it has now been polished and now looks superb.

AllPolished
Dirt gone
Vibrant colours
Finishing touch

I’ve attached this small video that shows the game working as it should, with no film slipping and lights and counter now working.

Working perfectly

It’s really pleased me this repair, as it’s another one of those mainly mechanical games. Dirt featured big time, and age issues have been overcome and the game given a new lease of life. Another one for my personal collection, it will go on now for many more years to come.

The best outcome that was possible, we have another superb seventies product that has been saved from the scrap heap.

And that is the biggest win of all.

Thanks for passing by, it’s always appreciated.

Grandstand – Kevin Keegan’s Match of the Day game

Here’s what the listing stated:

***NOT WORKING***

Spares or repairs

Fair overall condition some cosmetic damage as expected for a 56 year old item

Very rare well worth restoration if you know how

EBay

This guy sells retro games on EBay at exceptionally inflated, ridiculous prices. I suspect he doesn’t get involved with repair or renovation as he had this one advertised at over £30GBP but when I put in a cheeky bid for £12GBP he bit my hand off… I wasn’t expecting that! The usual mistakes in the listing such as stating it’s 56 years old when its actually 46, and stating it’s Very rare – it’s not, there were a few hundred thousand churned out and to be honest and they come up quite often on the sale sites. But I do agree it’s worth restoring and will pair up nicely with another retro football game from 1979 that i repaired a few months ago Bambino kick the goal football game. And what makes this unit even more appealing is that it is complete with both of its battery covers – now that is rare!

The game I have purchased
Absolutely filthy

This game was made by Grandstand in 1979. Here’s the original advert that appeared on UK TV promoting the game back in the late 70’s.

European footballer of the year 1978/1979 Kevin Keegan – questionable late 70’s advert

This particular unit is listed as Not working, it looks filthy from what I can see, but having experience with these games in the past the biggest issue is age related problems such as old components, track decay and battery corrosion. No doubt the first thing I will do will be to dismantle it, give it a thorough inspection and then a good cleanup both inside and out. And then we can look at the issues around why it’s not operating.

Assessment:

The unit has arrived today and it sure is filthy cosmetically. Like someone who has grown up throughout those 46 years it has its scars. It looks as if it has been placed against something hot, and shows a burn mark up one side.

How it looks on arrival
Caked in filth
Battle scars and burns

I have put batteries in and the good news is that there is life of sorts. By that I mean there is a distorted noise from the speaker and a flash of life on the screen and then it dies. Wiggle the start button and there are more flashes of life but that’s it. No other buttons seem to be working. I’m not tempting fate but this could be a case of the unit being just as filthy inside as well as out. But knowing my luck this will not be the case. Let’s have a look inside.

Repair:

First of all we need to get the unit open, remove the circuit board and get the thing clean. So let’s do that.

Utter filth
Circuit board
Push buttons to be cleaned, the rest is off to be washed. Even a dead bug inside 😧

As you can see in the pictures above, the inside hid a lot of accumulated dirt and grime, there were even dead bugs inside. Everything that could be washed was taken to the kitchen given a good soak, brush and rinse.

Off to the basin
Good clean and scrub
Drying on the window cill

Whilst I’m waiting for everything to dry my attention turns to the board. A quick inspection reveals that all tracks are in a fair condition and we don’t need to rescue anything there. The buttons on either end have been taken apart and all cleaned with IPA, I’ve also used the same method to clean the switches and the board and after checking continuity all contacts are working as they should.

Board before cleaning
Checking tracks
Note found under upper portion of main board

Now everything is clean, I resolder the battery contacts, check the buttons and all appears well, I attach my bench power supply, give it 6v, turn on the switch and we have life. No intermittent issues and a very loud sounding speaker. I turn this off and look at getting it all reassembled.

Unit now fully assembled, it is looking a whole lot healthier and apart from its burn scar is looking pretty good.

Where’s the dirt?
Transformed
Looking good

And when turned on it’s working just as well as it did back in 1979.

Result:

Sometimes these units just need some care and attention, and as I stated at the beginning all this really needed was a deep clean and service. Not a thing wrong with the electrical circuits apart from contamination on the contacts and switches.

All working. Job done

I’m now in possession of a lovely example of 70’s technology with slight battle scars. It’s had a tough life but now it has had a new lease of life and is good to go for many more years yet. It will take a place in my “Retirement home” collection of old discarded retro game units.

As always, it’s a win as we have prevented another unit being heaved into landfill.

Job done.

Thanks for passing by, it’s always appreciated.

Tomy / Palitoy Blip LED game

What the listing stated:

Boxed Tomy Palitoy Blip Vintage 1977 LED Game 

Good condition and powers up but need to shake it to make ‘ball’ move.

Could be a spring tension has weakened or something

Box is very worn

EBay

Blip – 1977 LED Game

This purchase kind of excites me as it was a couple of years before games started to go truly digital. The year was 1977 some 48 yrs ago from the current time of writing. It was labelled as a digital game however that was a bit of a misnomer, it was more an electro mechanical game as the battery source in this unit had only one purpose, to power the LED light source. The main guts of the unit are mechanical being powered by a wind up motor that does the majority of the work. However the mechanics within this unit are superb and it’s worth a look under the cover just to revel in its construction.

These units were released at the time when pretty much the only video game available was the tennis game “Pong”. The TV game units produced at the time were selling for around £70GBP where as this unit was priced somewhere around the £8GBP mark. Hence, it was a cheap option for the children and didn’t need extra hardware such as a TV and a power supply. However, it wasn’t a match for the far superior “Pong”. It was in theory a totally different and far more frustrating game.

Want to give it a try? There is a really good true to life version available from the App Store to play on your phone. Believe me it will have you cussing as it’s not as easy as it looks. So realistic right down to the motor noise and light movement. It’s really addictive and annoying in equal measure.

The App for iPhone…it’s frustrating

This video below by Randi Rain shows a total refurbishment start to finish and is a great source of information regarding the breakdown and repair of this item.

Breakdown and restoration of a TOMY Blip

Some history:

Blip was designed by Hikoo Usami for the Tomy Kogyo Co., the patent being filed in 1976 and awarded on December 19, 1977.

Tomy marketed Blip in the U.S. starting in 1977. In Japan, Blip was marketed as World Tennis and differed from the U.S. game by having the words “World Tennis” emblazoned on the screen and replacing the 1, 2, and 3 on the screen with silhouettes of tennis players. The Blip name remained on the Japanese version. In France, the game was marketed by Meccatronic. The German version was called Blip-o-Matic, although the Blipname remained on the case.

It is the timer which provides the motor function to the game. Upon the timer dial being turned, a spring is wound which then, via several gears, drives the arm upon which the LED light (the ball) is mounted. The movement repeats after the ball hits each player’s side 36 times, so it is possible to memorise the sequence of buttons to press.

Wikipedia

I’m really looking forward to receiving this unit and can’t wait to get it up and running again. I’ve been after one of these for quite a while.

For those who may be interested and who have a photographic memory this is the sequence that the movement repeats in its 36 movement cycle:

Pic courtesy of Tech Tangents

Assessment:

The unit is in good cosmetic condition considering it is 48yrs old. The box is tatty but usable and as always smells a bit musty (To be honest as expected). The mechanical condition is not as described and is a total non starter. It seems the winder may have even been overwound, I hope this is not the case. The “Ball” light does come on when batteries are put in but only intermittently and when pressure is applied in the battery area. However the contacts do look clean with no sign of battery leakage or corrosion. And I know someone has been in this unit prior to me as one of the four body securing screws is missing. God knows what I will find awaiting me within. The seller has been a little, how can I say it, inconsistent with the truth in his description of this unit.

But that’s why I buy these things. Let’s get inside and find out what is needed to get it back into being a working game.

My unit. And the ball light came on for a few seconds to allow me to take this picture. Then promptly died again.

Repair:

Open the case and this is what you are faced with.

Complex mechanical interior

If you remove the left and right control paddles you can get to see the mechanism running unhindered. However this one has an intermittent fault where the movement stops mid travel, there is something restricting its movement.

Something stopping movement

There is an inherent issue with these units where the gears have to be set up in exactly the right position or else it does not work. Similar to changing the timing belt on a car. This confirms to me that someone has been inside previously and messed with the gearing.

I also noticed a cog with a tooth missing, this was strange as to be honest it didn’t look as if there had ever been a tooth there in the first place!

Missing tooth
Was it ever missing?

Looking at its motion it transpires that this is another cog that just has to be in the perfect position and the “Missing tooth” corresponds with a flat post on the rear of the gear train. It’s missing for a purpose. This pleased me somewhat.

Calibration holes on the cogs correspond with holes in the shell base.

I put the cogs back in place paying special attention to their positioning and tried the unit once again. Here is the result.

Now a nice smooth movement

Next I’ve taken the light switch to pieces, I’ve cleaned all the contacts with IPA, reshaped the contact and put back together.

Switch dismantled, cleaned and reassembled

I’m pleased to say this did the job, the light works fine and there is no longer an intermittent fault. It’s all that was required.

I have reassembled the unit, given it a good clean and it looks pretty smart if I say so myself. It was already well oiled so there was no need to add more at this point. It is now fully working and will last a good few more years yet.

Now Working

Result:

A successful repair of a 48yr old toy game. I’m really pleased with my purchase and it’s another cracking example to add to my ever growing collection.

All clean and looking smart

Repairs on these games need approaching from a different point of view. The electronic content is minimal and mechanical workings are the order of the day. Look how it has all reversed in today’s gaming world, that’s advancement for you.

Really pleasing positive result here. Another one saved from landfill.

Thanks for passing by and reading this post. It’s always very much appreciated.

Earning on YouTube

I follow a number of channels on YouTube. It’s the only social media site apart from this one that I do get involved in. I have absolutely no intention of ever making a living on these platforms as to be honest I couldn’t really be arsed to.

Hugh tells you how it is

However a lot of individuals nowadays want to do just that and make their livings on line.

Now Hugh has a very interesting site for someone like me that likes anything from the retro era. He’s been without a smartphone for over a year and his progress without one has been really interesting to follow.

Hugh does earn from his online presence but to be honest it isn’t a living. He goes through the figures in this video that show all the hoops you have to jump through to earn a living from having an online presence.

Bronica SQ-A / The Frankenstein project Pt:1

To find out what I am trying to accomplish with this project please refer to my initial post: Bronica SQ-A Medium format camera

Task:

To build a usable, basic issue, medium format camera (Bronica SQ/SQ-A) from damaged items and spare parts, for as little outlay as possible and shoot one black and white, and one colour roll of film as proof of its successful completion.

Getting started:

Building a camera from damaged parts is no easy task when the name happens to be a high end brand and any parts that are available, are being snapped up by others to service their own stock or to break up for sellable parts. I’m going to keep a running total to try and build this as cheaply as possible, and to keep track of this total I’m going to use my trusty Psion Organiser II LZ from 1989 to keep a tally.

First purchase:

The first purchase has been made and it is for a 6×6 120 roll film back unit with dark slide. I think I’ve paid quite a good price for this item. This is the back piece that fits on the rear of the camera. Here is what the listing stated:

ZENZA BRONICA SQ 6X6 120 ROLL FILM BACK WITH DARK SLIDE Signs of wear, untested.
Uk Buyers Only Please

EBay

First purchase, the film back.

And the total paid including all postage is £20:94GBP. Let’s now start the running total in the Psion II LZ.

Running total

All I can really check at the moment is cosmetic condition and this looks a little beat up, however I don’t really care how it looks externally, as long as it’s light tight, that is all that matters and I won’t even be able to check that until later on in the build. Cosmetically I will attend to it, if I feel so inclined at the end of the project, for now it’s ability to be light tight will be my major concern.

Assessment:

The unit has arrived and yes it has seen use, but not in a few years I suspect. The old smell hit me the second the package was opened, it’s kind of a reminiscent pong from the past, however I’ve got to see beyond this.

The light slide seems fine, however the surrounding frame has been bashed and a small bit of frame has gone missing. There is also a screw missing and I suspect the area that is missing the screw may well have been glued down. there are some slight rust spots on the exterior framework, however everything inside appears to be fine apart from some light seals that will probably need replacing. The rollers inside are grubby so a good overall clean is in order.

Annoyingly the ASA markings on the dial atop of the roll holder are missing. I will make something basic up to remedy this issue. Again it’s an exterior issue and I’m not too fussed at the moment.

Yes there is some work required, but there is no rush. And thankfully I don’t see anything that really scares me about it. I won’t really know how it stands mechanically until I find a suitable body to attach it to. I have that to look forward to in a future post.

Repairs:

The ASA dial. Simple solution here, until one becomes available sometime in the distant future, is to use some very small dymo labels I have printed. I will cut these down to size and put them in place where they should be on the dial. Quick and temporary solution a’la Frankenstein. No need to over manufacture things, this will do fine.

Size 9 dymo labels
How it should look
How mine currently looks
After I’ve added some ASA numbers- temporarily

The old asa wheel has been cleaned to remove the original glue, and temporary stickers have now been applied. This completes this fix for the ASA dial, for now.

Two items to make one good unit

Edit: I’ve managed to obtain a damaged roll back for a grand total of £5:76GBP, absolute bargain and it also has a working ASA dial. So I’m hoping I’ll be able to use this donor to help in the repair of this item. I’ve used a combination of parts from this and the earlier roll back and I’m happy I have a good working unit. We now have a proper ASA dial off of the spare unit transplanted onto the old unit.

Front frame:

I’m taking this off to give the whole area underneath it a good clean. There are some film guides under this frame that are contaminated and that could cause a scratch on the film, I’m going to clean this whole area under the frame and will then reassemble. The cartridge slide is in a good condition and has just required a polish. Apparently this front frame is prone to breaking and the screw holes splitting, as it gets quite brittle. This has happened to this unit, and I’ve found a guy that 3D print’s replacement front frames and I have ordered one of these to ensure that the whole frame is secure and light tight, as currently one corner can be lifted and this could cause a fogging issue. At a cost include postage of £12:75GBP it’s a small price to pay seeing the only way to get one nowadays is by purchasing a donor unit at cost far exceeding what I have paid here.

The new frame, will be black
The old frame with broken corner and damaged screw holes
Damaged area of frame in situ on the roll back

There are a couple of screws missing of which I have plenty of spares so these will be simply replaced. I’m happy now that this portion of the camera is in a good condition and will soon be ready to be put to use.

Before
After
Dirty seals
Damaged framework
Removal of the frame presented years of debris and filth that needed cleaning as well as a requirement for some replacement parts

There was a lot of contamination under the plate when it was removed, I was quite amazed just how bad it was. This has since been cleaned prior to the new frame and seals being put back into place. When everything is re assembled there will be another clean, I will also be using compressed air to finally clear any remaining debris from the roll back. Edit: the 3D printed frame has arrived and to be totally truthful it’s not much good. The part where the slide goes in is not usable and I’m not confident this will be as light tight as first thought.

Good front frame from the donor spare unit

However the spare unit I purchased has a good front frame that just needed a tiny bit of adjustment to work, I’m now confident the roll unit will work as it should.

Light seals:

To be honest there are only two immediate areas of concern that I can see. All other light seals seem to be sufficient. I already have plenty of light seals material from where I fix other cameras so this should be simple enough to replace.

New and old light seals replaced

There were only two pieces that needed replacing, these were both on the roll film back. All other light seals were fine.

Rust spots:

These are purely external and there are no issues inside the cartridge. However I may just give them a very fine rub down and a quick spray with a black gloss to just make them look better. Then again I may not, and then I’ll attend to the cosmetics once I have completed the project. Edit: I’ve decided to leave this for the moment and will attend to this sometime in the future as it is not affecting anything at this stage.

Film cartridge:

Again this has just been cleaned and some contamination has been removed from all rollers and guides within. I have adjusted the back plate pressure pad for the film and also given this a good clean to remove any contaminants. I’m happy the internal cartridge is in a good condition and only requires a light clean. This cartridge is superior to the one I have obtained as a spare so this will be the one i work with. I have replaced all the exterior screws to replace the original ones as they were all a little crusty and contaminated.

New screws. I will touch the heads up with black dye

The whole roll section has been cleaned with tack cloths and compressed air to ensure all contaminants have been removed.

I’m going to store the whole roll film back, in a sealed plastic bag with some Silica gel packs to try and remedy the mustiness that I mentioned at the beginning of this post, though I must admit after all the cleaning and replacement of parts, the issue has reduced immensely. Some exposure to sunlight on a window seal usually helps immensely. That’s where it’s sitting for the moment. It’ll go in the bag with some silica gel, during the more inclement weather.

Outcome:

This part has been the most demanding part of this project so far. I’ve looked into the possibility of using 3D made parts, but I must admit defeat here. The items are about 80% ok, there are holes missing that should be there and as it’s a two piece fix you are then introducing glues, and potentially increasing the chances of light accessing the one area you want dark. Maybe in time they may perfect it. I was exceptionally lucky to obtain a spares unit for literally one pence. Yes one whole pence. It cost £5:75 to post making a total of £5:76GBP, but in many aspects some of its parts were far superior to what I already had. I am happy that this part of the build is now complete.

All good to go. Please keep an eye on the other blog posts that are coming regarding this project.

Grandstand Invaders from space game

What the listing stated:

Can’t get to turn on unfortunately. No battery cover. Any questions please ask

EBay

Dirty unit
No battery cover

I know, there is no battery cover, however I have already sourced a seller of one if needed. This item looks quite dirty so a good soak might be the order of the day to get started. I’ll wait for its arrival before I jump to order any other bits for it.

Now as I’ve said in the past these units fall into that crazy price category on the selling platforms as the “New Antiques” of today. For an item that was low cost, somewhere between £25-40GBP when it came on the market, they can certainly command a wide range of crazy prices, here is an example of price ranges from today:

The massive range in prices for these units

This one I purchased today only came up for sale about 3 hrs ago and I thought it would have been snapped up by now, it hadn’t so I didn’t hang around any longer and purchased it for a total of £16:38GBP including its delivery. I’m not going to get too smug yet, as for all I know I may have just purchased an empty shell. Let’s wait until it arrives.

Here’s a little history of this unit:

Grandstand “Invader from Space” is a tabletop LED game dating back 45 years to 1980. Four ‘AA’ batteries power the unit or, alternatively, the Grandstand 5.5V@300mA power adapter (or an equivalent power pack) sold separately. The game, licensed to Grandstand, is a copy of Epoch’s “Invader from Space”

The company initially behind the “Grandstand” label was Adam Imports Ltd., (from 1980 Adam Leisure Group Ltd. and by 1983 Adam Leisure Group PLC) founded in 1973 by Chris Rycroft and Les Kenyon of Harrogate, UK. The company initially started as a mail order company and was the single largest supplier of calculators in the UK by 1974. By August 1978, George Bassett had acquired a 75% holding in the capital of Adam Imports for £750,000 cash, plus 60p in the pound of profits before tax in excess of £500,000 for year to December 31, 1978. Adam Imports was re-acquired from George Bassett by Chris Rycroft in 1980. It chiefly imported electronic products from other manufacturers such as VTech, Epoch, Tomy & Entex, selling them in the UK re-branded under the Grandstand name.

Wikipedia and others

So that’s the history

There is a good link to a similar repair on YouTube from a guy I follow named Stez Stix Fix, it’s very much worth a look and he has a great if not sometimes crazy way of diagnosing and repairing items. A cool guy though.

The Grandstand invaders from space game

Anyway back to my own purchase.

Assessment:

I must admit the unit doesn’t look as dirty as in the original pictures. The battery cover is missing and there is a crack in the side and a deep scar at the bottom, this won’t be too much of an issue if I can weld it all back together. I will still give it a good soak to clean it all up though. I’ve put four batteries in place, and the unit is definitely dead. There are no loose wires, voltages are getting around the board according to the multimeter and nothing is getting hot. There appears to be no short circuits, and then I notice this, capacitor CO7, slight bulge on top and what looks like leakage from the bottom. We have a candidate as to why this unit is not working.

CO7 looking unhealthy to me, you can see the component to the left that looks like it’s covered in a fur ball. The result of the old capacitor “coughing”

I’ll whip this out and see what we have but I suspect this old capacitor has failed and is causing an issue, heres hoping I have a suitable replacement.

Repair:

This little beast is a 330uf 10v electrolytic capacitor. I have none available so have had to purchase a pack of ten. These should be here in the next few days. There are three other old electrolytic capacitors that I will also change whilst I’m in there, as these are all likely to fail at some point soon. These components are now all around 45 years old, it’s a wise move to change them out.

One very dead capacitor removed.

I’ve ordered a 3D printed battery cover to replace the one that is missing. This should be here in a couple of weeks.

Whilst waiting I have cleaned the inside and outside of the casing as best I can. I still have a piece of broken surround to repair, however this is just a simple glue and a little bit of support job.

Case inside and out cleaned
Broken surround repaired

The surround that was broken has been repaired and secured with some nylon soaked in a superglue compound inside the casing. It’s rock solid. Outside the break is hardly noticeable. The break is secure and much stronger now.

New capacitor here

I’ve replaced all the offending capacitors and the unit remains dead. I’ve reflowed most of the board as there were some dry solder joints. I’ve also rewired the bridge from the control panel to the main board as one of the wires here had broken.

Bridge required resoldering

After using the multimeter to check some traces and components it’s now pointing to this component (a power transistor D882) being the cause of this catastrophic breakdown as its readings are all over the place. I suspect this item has overheated, the capacitor has blown and then it’s just died itself. I’m probably wrong, but I know what I mean. Probably just a catastrophic chain of events that all contributed to the units demise.

D882 transistor – power regulator

And as usual I have none available so will have to send for some new ones. The new components have arrived and the new power transistor has taken its place on the board. Now reassembled I place some new batteries in and the unit comes to life. It was the power transistor at fault, I should have really checked here first after seeing that damaged capacitor at the beginning.

All old components removed and replaced in this unit

Not to worry though as it’s had a good overhaul and has been totally recapped as a precaution. I’ve used some conformal coating on a few tracks that had some copper exposed after a good clean, to ensure they don’t deteriorate any further.

It has life

The unit is looking really good and these items were traditionally very loud and this certainly is. It’s working well just as it should do and I’m exceptionally happy with this repair. I’m still awaiting the battery cover that I have had 3D printed and this should be here in the next week to complete the fix.

No score
Here we go
3D printed cover arrived. Minor adjustments needed but in all a good purchase

So with that I will bring this build to a conclusion. It has been a fun project, I’ve learned a number of things about this circuit board and gained valuable knowledge.

But best of all we have rescued another item and saved it from landfill.

Winner 🥇 👍

Original Nintendo pinball game – Non operational

Hopefully this will be a simple repair, but who knows it might just be a little more technical.

This game is built for the game boy colour console and is an original Nintendo product, it is the Pokémon pinball game. I’ve purchased something I never normally buy and usually detest buying, an item with the battery cover missing. Damn it, there is a fortune waiting to be made by anyone who owns a decent 3D printer, with the amount of missing battery covers that are waiting to be reproduced out there. Edit: ( Just looked on line and it seems the gaming community are already on the case, loads of options available, great to see) Anyway I’ve brought this unit as it can either be kept to await a suitable battery cover or passed straight on. Edit#2: I have, in anticipation of its arrival already ordered a suitable 3D replacement cover from a UK company. It was probably the best priced and best looking print to be honest, some of the others looked a little rough and postage was excessive to say the least. These guys at Cool spot gaming were the best in my opinion.

Released in Japan in 1999 this game made it to European shores in 2000.

These games came with a rumble pack at the top of the cartridge that simulates the vibrations of a normal pinball machine, and I believe this is what the single cell AAA battery is for. And as it is a black cartridge this indicates it can be used on the GameBoy colour and original versions. I have purchased this for about half the price that a good working one with battery cover sells for, now that I’ve had to pay for a 3D replacement battery cover I now move into the higher end price of the cartridge valuation, however I do have a few pounds worth of wriggle room should I decide to sell, considering most of the ones on sale at the moment are missing the battery cover and commanding horrendously high prices. I’m comfortable with that. That said it will go into my personal GameBoy collection anyway. Let’s get it working.

Here’s a link to the actual 3D print program for the battery cover on Thingiverse, if you should ever wish to print one yourself. I have absolutely no idea about 3D printing so this is just like brain surgery to me: 3D print program

Assessment

A nice tidy little package has arrived clean, battery cover missing as stated and exterior looks nice and clean. Original label is intact.

Repair:

New 3D battery cover has arrived and this fits perfectly, no issues here.

I’ve placed the unit into my GameBoy to check what occurs, and just as posted it does not progress beyond the Nintendo start up screen. I’ve opened the cartridge to do some basic checks and cleaning, the cartridge contacts have been cleaned using an eraser and some IPA, but in all honesty they were already pretty clean. I’ve checked the onboard battery and this is healthy at 3v as it should be. Cleaning competed, I recheck the game and the results are the same.

Battery tested
Contacts cleaned

Next I’m going to reflow the joints on the ROM chip on the right hand side of the board, the one that has the letters MX on it. These pins or the ones on the RAM chip directly beside it are well known for having bad contacts and often need reflowing/tacking down. It’s something that seems to occur over a period of time on these game cartridges, just plain bad contacts.

ROM chip on the right with the RAM chip on the left, both are notorious for developing loose contacts

All items on the board have been reflowed using hot air, with extra attention being paid to the two chips described in the picture above. I removed the battery prior to doing this as the last thing you want is exploding batteries. With the battery back in place and the game now reassembled it’s now time to test.

And it works including the rumble pack feature.

Working

I can only presume the hot air reflow has fixed an issue with joint continuity on one of these chips as expected. Excellent, another item has been saved from the bin and can now be added to my collection.

Another little project to put to bed, there always seems to be an issue with these games after a good number of years where the solder joints just become unstable. I don’t know if it was the solder quality they used all those years ago or the heavy use and abuse the games endured during their hey day. At least we can fix them and ensure they are still good to go and enjoy for a few more years yet.

Thanks for passing by.

Bronica SQ-A / The Frankenstein project Pt:3

To find out what I am trying to accomplish with this project please refer to my initial post: Bronica SQ-A Medium format camera

Task:

To build a usable, basic issue, medium format camera (Bronica SQ-A) from damaged items and spare parts, for as little outlay as possible and shoot one black and white, and one colour roll of film as proof of its successful completion.

Getting started:

Building a camera from damaged parts is no easy task when the name happens to be a high end brand and any parts that are available, are being snapped up by others to service their own stock or to break up for sellable parts. I’m going to keep a running total to try and build this as cheaply as possible, and to keep track of this total I’m going to use my trusty Psion Organiser II LZ from 1989 to keep a tally.

This may be a strange situation where Pt:2 and Pt:3 of this project gets published before Pt:1, quite simply Pt:1, the film back. needs a fair bit of work still doing to it.

Third purchase:

And the third purchase is for an SQ body. This appears to be well used, but appears to be in a working condition. Here’s what the listing stated:

Zenza Bronica SQ Body Only / Medium Format 6×6 Camera

Condition:

Used but still in good usable condition with usual signs of use – see photos for details please. Fully tested and in perfect working order.
Supplied with: Camera body as pictured.

EBay

Now I’m happy with this purchase as well. Not quite the SQ-A I wanted but to be honest the only difference is mirror lock up and metering that I don’t really need so I can live with that, we all managed prior to the metering being done for us, I’m sure we will all survive now . (Oh how we have been pandered over the years)

The Bronica SQ body I have purchased

I’ve paid the grand total if £73:75GBP for this body including the postage. There are some bits I will require to complete the body, namely a focus screen and waist level finder that could be a bit pricey, and a winder for the body. Now, the winders are pathetically expensive at around £60 for a bit of plastic. I know a guy who 3D prints a good alternative for a fraction of the price. And that will be the route that I take.

So over to my trusty old Psion II LZ for the running total for these first three items.

Current running total

So the total for these three items comes in at a total of £150:94GBP, and in Bronica terms this is extremely reasonable!

Assessment:

The parcel has arrived and yet again I’m really happy with this purchase. Very well packaged, a very faint age related mustiness that I guess should only be expected on an item that is now 45 years old. It seems to work just fine. I have connected the lens and that seems to be working ok, I just need to verify the shutter speeds are all correct. There is no battery in the base and this needs replacing as this is what controls the shutter speeds. Without the battery the mechanical shutter works, but only at a speed of 1/500 of a second. (Edit: the battery has arrived and after testing i can confirm that all speeds are operating as expected). The film back fits fine but I still have some work to do on that before I can say that this part is working ok. Overall I’m satisfied with what I have for the price I have paid.

No battery
No winder
A selection of covers for the sides, top and bottom are required

Repairs:

Not so much repairs but additions that are required, such as a crank winder arm and a focus screen, a new battery and a selection of covers to protect the central unit in transport. All horrendously over priced and i will deal with these items in Pt:4 of this project.

Outcome:

Current situation, looking good, smelling old. Not me, the camera 😂

We are almost there. The lens is fine, the main body is fine and just needs some final testing. The film cartridge is the item that needs the most attention and this will hopefully be finished when I have the new front plate that is being 3D printed. The next instalment will be just a tidy up with all the little bits I need to complete the build. These small pieces in Bronica terms are so bloody expensive, or should I say extortionate, can be obtained at a fraction of the cost elsewhere, you just need to shop around, if you are happy to have a non named spare part as a stand in. I’m happy with that as these parts have absolutely no effect on how the camera performs, and what we want to achieve at the end of this project, that being a well exposed two rolls of negatives that will produce a number of well presented photographs.

All good to go. Please keep an eye on the other blog posts that are coming regarding this project.

Bronica SQ-A / The Frankenstein project Pt:2

To find out what I am trying to accomplish with this project please refer to my initial post: Bronica SQ-A Medium format camera

This may be a strange situation where Pt:2 and Pt:3 of this project gets published before Pt:1, quite simply Pt:1 needs a fair bit of work still doing to it.

Second purchase:

The lens. Probably the most important purchase of this project. Looking for a “cheap” lens is normally not the thing to do when exploring lenses as you do really get what you pay for. You want good clarity? You need a good lens. However this lens came on offer and what sold it to me was that there were no scratches and fungus in the lens, and that was music to my ears. It is a duplicate of a lens the owner already has and was surplus to his requirements. He has also supplied recent proof of photos taken on this lens and i believe he has sold me a little diamond to be honest. Everything about it seems good. There is nothing really to do to it, so no maintenance apart from maybe a light external clean and that will be it until everything else comes together.

Here is what the listing stated:

This is the S version of the 80mm lens and although there’s a slight difference in the lens design on the PS version, I’ve compared the two and couldn’t see any real difference other than a slightly more modern colour rendering. The T mode is also working without issue. This lens has been my main user lens and has never let me down. Glass is clear of fungus, haze and scratches. Aperture and shutter blades are snappy and clear of any oil. Shutter speeds are accurate and the lens produces just delightful images and is massively underrated. I’ve included several shots taken recently with this lens mounted on an SQ-A as per the examples. Focusing is smooth, apertures have a nice smooth click and the lens focuses just fine all the way through the range. I will include the origin box as well as the front and rear lens cap with the lens

I’ve paid the total cost including postage of £56:25GBP and I think that this is an absolute bargain for what I am getting. It’s an 80mm f2:8 Zenzanon-S lens in its box with two end caps. I’m really pleased with this purchase and there is not a lot else I can say.

So here we have the scores after two purchases, the 120 roll film back and this lens. Over to my old mate the Psion II LZ for the running total.

Running total

So the total for two items currently sits at a comfy total of £77:19GBP so far, with an average per item price of £38:60GBP. And in Bronica terms that is quite reasonable!

Assessment:

The lens has arrived and to be honest it has surpassed anything I could ask for, for the price I have paid. For this project it is in perfect condition with nothing required regarding any repairs. It’s good to go.

Boxed
Original inserts
Both end caps

And out of the box the lens is lovely and clear. Just a few bits of dust but that is nothing at all.

Original end cap
Nice and clear
No fungus

Repairs:

None: I know this is boring on a repair front, but for this project it is the perfect result.

Outcome:

All good to go. Please keep an eye on the other blog posts that are coming regarding this project.

Plastic Gear Repair

An excellent post. I often come across broken plastic gears and they are the Bain of my “Hobby life”

Maybe I need to start repairing my own gears or invest in a 3D printer.

We’ve seen several methods of repairing plastic gears. After all, a gear is usually the same all the way around, so it is very tempting to duplicate …
