so i was a dork when younger (yes, past tense there) and i had one of those “250 Experiments in 1” sciency type kits. one of the experiments was a ‘build-your-own-electronic-musical-instrument’, which instrument consisted of a bunch of circuits, two wires, and a strip of graphite (i.e., draw a thick line on a piece of paper) on which to place the wires’ ends.
notes were changed, trombone-style, by changing the length of graphite between the wires.
but that’s all i got! does anybody have any idea what the assorted circuits would be? my friend is doing a show next week, and needs some wacked instuments. and i can’t seem to find anything on the web.
thanks in advance,
The one I built did not have a large field so you could only use your finger.
It worked well enough for the girl I made it for to get an A in her science project. She apparently played a tune with it.
Explaination
I had the schematic .She had the junk radio. and some parts I sent her to Radio Shack to get. I did not have much time so I soldered it together.Made sure it worked and left everything else up to her.
