After running and other outdoor pursuits took over my life back in the eighties mart, I flogged a lot of my electronics stuff, and gave some away, but I knew that one day I would return to the hobby, so I kept some of my most important tools and components, and I mothballed my workshop in the loft. I never lost interest in electrics and electronics and although I was a machinist and mechanical engineer, my electrical knowledge spilled over into my job and I ended up repairing, installing and rewiring as part of my working day.

After retirement I started pawing through some of my old electronics books and realised that the excitement of building something had never gone away, so I opened up the lab and started pottering around. I have always been self taught concerning electronics, but the passion has driven me on to read and learn but mainly through practical experience. Some work and some don't, but sometimes you learn more from the ones that don't work...

I'm glad it has encouraged you regain your interest in electronics mart, you are a mine of information and it's good to have someone like you to bounce my ideas off...
Many years ago (early eighties I think) a distant member of the family asked if their son could come and have a look round the lab. He was about sixteen and keen on electronics. We cobbled a few bits together and produced an amplifier and a couple of oscillators that played interesting tones and sounds.

He was so impressed, and so was I, most people glaze over and get so bored when I rant on about electronics.. I heard later, that he went to university and secured himself a career in electronics. The last I heard he was some 'big shot' in a well known electronics company in America....I like to think that I had contributed to his interest in all things electric...

Watch this space for future experiments.....

All these components (except the transistorised ones) bring back unhappy memories, this my be just Radio Ga Ga.

Nice project chap. Being a mechanical engineer, electronics is one of the black arts as far as I am concerned.

I used lots of electronic equipment including the scopes pictured earlier for "simple" jobs when I was gainfully employed, as well as all sorts of other electronic kit.
We had banks of single or twin beam 'scopes in multiple groups of fourteen, then when we saw something out of the ordinary we selected each wiggly worm to appear on frequency analysers, but I hadn't a clue how any of it worked.

I learned how to read complicated electrical drawings and was licenced to repair combat aircraft engine control amplifiers down to board replacement level, but not board component level a-cause I hadn't a clue what each component was, let alone what they did.

I haven't a clue what most of the components in your circuit diagram are, or do, but I am impressed by your knowledge and skill and that of the other "wizards" that have posted on your thread. I hadn't realised Besoeker is also located in dear old Donny. I have fond memories of my time there.
I'm also impressed by your woodwork design and construction skills as well.

Please keep us updated. I think it is a really interesting project, and it will have a use at the end of it all.

Chapeau removal to you sir.

Thanks Fruitcake your support is much appreciated. I'll try to keep it easy to understand and hope that more posters look in on the project. I just thought it might add a little more interest and take our minds of covid and brexit for a while....
