Just to prevent September will pass without any post here's is a short update.
I tried to build a Slayer exciter but that didn't work out very well,I think I need a smaller gauge of wire.
So for now that project will delayed.What did work though was the breadboarding of the Drawdio:
But I will not put all the components on the pencil because the speaker I use is much bigger.
Another subject:I bought 7 vintage radio's today and one a couple of days ago.
Some of them are:Philips 759,Erres KY534,Philips BX400A,420A,520A
