Its seems as though google has begun to deplete its vast resources for unknown information IMO, however using some unorthodox search techniques I stumbled upon a very interesting noise site of Jessica Rylan. The machines which she built for her Noise gig are fairly strait forward, using 8038, sn76477s, and NE555s chips. More info along with some good building and testing stories can be found at her link http://www.irfp.net/Machines.html. She also gives props to Forest Mims and the engineer’s handbook, BREAK IT DOWN!
