Noisy noise
Jul. 23rd, 2007 09:27 pmThe results of today's experimentation in the physical computing lab (192kbps MP3, 0'52"; warning: awful noise). The circuit involved a CD4093, with each oscillator in the chip modulating the next. There were two binary dividers in there somewhere as well, and the whole thing was controlled with a couple of photoresistors. (Circuit suggested by Handmade Electronic Instruments, which is an awesome book for people interested in analog electronics and circuit bending-type stuff.)
