How the camera looked on arrival

The problem with this camera is that it had a focus issue and currently it is dead electrically. Quite looking forward to getting into this one as it maybe quite a simple fix. That said, it could be that the whole internal circuit needs replacing which will mean the camera could then be added to my ever growing spare parts collection.

On receipt this camera cosmetically is in excellent condition. Even the normally broken battery door catches are in fine condition on this model. The unit is very dead though and it looks as if a battery has leaked inside causing some corrosion. I suspect some of that leakage may have travelled a little further as it seems the wide/telephoto switch on top feels a little rough when it should be a smoother movement. I’m going to have to get inside this one and have a look around.

Battery leakage evident

I’m afraid it’s disappointment with this unit. The battery leakage is so severe it has pretty much dissolved a number of components, ruined the board tracking in a number of places and corroded the wide/telephoto switch beyond use. The trusty multimeter confirms that the main circuit board is about as much use as a chocolate fire poker – useless. I’m afraid this unit is resigned to use as a spares donor for another day.

Severe corrosion from batteries evident

As you can see above, the batteries have been allowed to leak causing a catastrophic amount of damage to the circuitry. I have cleaned tested used a specific cleaning solution and scrubbed the circuit to no avail. My friendly multimeter has confirmed the circuit is beyond economical repair.

Wide/Telephoto switch totally corroded

I have stated in earlier posts that there needs to be a greater awareness of the frailties of cheap batteries. There is a particular brand I know of that has adopted the name of a large photographic company I used to work for, and to be blunt their batteries are utter crap. They start to leak very soon after their demise and the acid/alkaline leaks everywhere, they should be avoided at all costs and I very much suspect this specific case is due to such advice being ignored. High use items such as cameras require an adequate battery, please do not cut corners here as it is a false expenditure.

Damage caused by corrosive substances

The saving grace from this unit is that I have a few items that will be put to use at a later date. The body shell with its intact battery locking mechanism will probably earn me more than the whole camera cost originally and that will still leave me more as spare parts. It’s just a shame that cost cutting on the power supply has damaged so much of this unit. I cannot impress on you enough, do not use cheap batteries, you will potentially pay the price of permanent damage if you do.

I have had to seriously clean and decontaminate my work board due to the immense amount of contamination that came from this unit, I’m glad I wore protective gloves whilst attempting to clean this unit.

What I have managed to salvage

I have salvaged a complete body shell with working battery locking door, a lens focusing unit, a rear screen and holder, a number of screws, a flash unit cover and a 330v 100uf photo flash capacitor. As well as a nice leather case.

Unfortunately not every unit is salvageable, however we have parts to assure the next unit may not go to waste. A healthy spares store is always welcome and all I can say is…. Onwards and upwards, bring forward the next repair.

First steps

So most of my adult life I have convinced myself that despite having a hatful of interests there was nothing that I was particularly any good at. It’s strange really how you always knock yourself back if you don’t have that much confidence. In truth it really is quite the opposite. I started out in Photography way back in the days before digital when you had to get your hands wet to produce results, for me the old Silver halide era of photography cannot be matched or equalled and personally I think anyone can be a photographer these days, however give them developing tanks, print dryers developers and fixers an enlarger and then ask them to dodge and burn prints and then retouch them and the result might be slightly different. I remember days when I used to photograph weddings and shoot maybe 6-8 rolls of film, a friend of mine in the digital arena shoots maybe 2-3000 exposures per outing! Wow, she will never experience the fear of having a blank film post processing.

On top of this I’ve had an interest in electronics from an early age, I used to visit jumble sales as a kid, buy old radios and repair them and sell them on to get some pocket money. I obtained a city and guilds in electronics back in 2000 as well as an “A” class Radio Amateur qualification (M0ESB) so yes I’m a Radio amateur as well. I could have ventured into a job role utilising this however I preferred to maintain it as a hobby as I didn’t want to fall out of love with electronics.

I also enjoy arty stuff, I love painting both pictures and stuff, tarting stuff up – you know what I mean. I have recently had lessons in the Bob Ross method of painting with a local tutor and I really enjoy this. I’ve always enjoyed making models and painting them and I like building small dioramas as well so I can be quite crafty when I put my mind to it.

So to return to the start when I was searching for my worth as such, I have decided to combine a number of these hobby/experiences and I will be purchasing old unloved equipment, making it good “Tarting it up” and hopefully moving it on either for decorative purposes, for use as props or even returning it to its original purpose.

The site is new and I’ve kind of jumped the gun by getting this up and running before I have any projects on the go or even stock to use in those projects. Hey ho, that’s the way I roll is anyone else as ass about face at doing things as I am?

Hopefully I can record my progress through this site that is a new venture for me as of Feb 2023.

Maybe you as a visitor will follow my journey, maybe you will pass on through, however please feel free to feedback any constructive advice as we can all learn from that.
