I had a go at that Formant Synthesizer, that was fun.

Oops, that was Elektor. Did that 9 channel digi-proportional radio control from PE.

He he! So did I.

I was always building synths in my teens, and was in a rubbish band of hopeless teens that sounded like Kraftwerk on diazopan.

The Formant looked the dog's but sounded like rubbish mostly, but occasionally you'd get a brilliant, other-worldly noise out of it.

Sadly we didn't have samplers then!

p.s. that would be a 'Chebyshev Filter' then?

well, there are lots of ways of spelling it, or, for correctness, use the original cyrillic. Чебышёв

Ahem....... I had a sampler that plugged into the back of my Spectrum. Really.

Only thing I ever made that worked was a 100w MOSFET power amp.

Those were the days, magazines stuffed to the brim with stuff you could never get working.

PE in particular...

And the Practical Wireless "Telewriter"...

Oh! Tell me about it (I think I tried wirewrapping the thing)

I did successfully build the PE UK101 kit computer though.

Despite the fact that most of the chips in the kit were mfr's rejects and needed to be replaced.

Well there's a lot to be said for loud.

My music teacher said that if Mozart had had a 1KW PA, he would probably have tried to stun his audience rather than trying to impress then with the delicacy and whimsy of his compositions.

Though it's easy to criticise the magazines for putting out stuff that is basically unrepeatable...

My design of a security camera switcher proved to have been designed in such a way that it worked with the CCTV cameras I had, & when one died, the replacement wouldn't work until I'd frigged about with the circuit a bit.

So far as I know, no one has built another system.

Just as well really.

Perhaps if you ditch the Giant Alien Lizard Spotter circuit, then it could be more commercial. After-all it's only a few caps and res and a 'dual' 556.

Correct as ever Threaded!

are so wonderfully reliable and stuff, why have so many of them got failed sections in them?

They are reliable because they have sections - partial failure, not complete.

It's like RAIDs - drives still fail, but data is saved.
