made a follow-up on the Jam Jar for an exhibition based around one man's huge hifi collection.
decided to mix my own collection of "useful things to one day use" with his. i used 24 jam jars i found in his garage (used to store nuts and bolts), put in 24 mini speakers, driven by 24 new amplifiers (simple 386 circuit for you electronerds out there).
dug up a pcb containing a full octave set of oscillators i had lying around - used to be the heart of a very disposable crappy italian organ - and added 12 dividers: et voila, 2 octaves of square wave goodness. tweaked the oscillators' caps to end up with a 60/40 PW wave for improved harmonics, so the 'wah' sound jumps out a bit more when you twist the lids.
the wooden base i made from the man's old shelves. recycling ftw!
exhibition was quite funny, nice to watch the audience go wild on this thing.
video or sound coming soon, hopefully.
