You have to be careful of some of those little projects that used to fill the gaps in the magazines. In the days when I built music synthesisers I saw a circuit for a vocoder, which said it was using logic chips by using a very small linear region in them that meant they could be used as dirt cheap amplifiers. I never tried building this circuit at the time, but I looked for it again online recently and found a forum post by a guy who said that he had written the original article. He said that for fun he'd send in these quasi-plausible circuits he dreamed up in his tea breaks, just to see if any of them got printed. He said the vocoder couldn't ever work. I wonder how many people tried it? Anyone remember those Bernard Babani books? Someone once told me many of the R. Penfold circuits never worked very well or never worked the same way twice. I see the publishers are still going strong: http://www.babanibooks.com/. John S -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
