[sdiy] Crackle Box PCBs

[Fernando de Izuzquiza]

Hi Rafael and all,

I built yesterday my crackle box and can't stop playing and 
experimenting. Looots of fun!
I found one capacitor value different from the two schematics posted 
here: C4 is 10n in one and 100 in the other. I soldered the 10n and 
have the 100n detachable (for a total of 110nF).
Just different range of weirdness. I will experiment with other C4 
values.

Apart of using my body or any object, water, etc. I'm using capacitors, 
photocells, etc between the contacts to experiment. Endless fun. With 
photocells (+LED) it could be voltage-uncontrolled !   =:)
I'm using screws as contacts by now. I'll try to research more on this.

I'd like to experiment connecting some krakadoos together too.
And an electret mic as The Peasant suggest. The Peasant versions are 
cool, wow!

And want to try with a 12'' speaker to listen to the low growls...

This is an endless incarnation circuit, I see.

This is gonna be a great summer (except for the neighborhood)
Thanks all for resurrecting this complex oscillator

Best wishes,

Fernando
