[sdiy] Re: Vactrols and contact mics

[bill bigrig]

Howdy,
 Once again, "Handmade Electronic Music" second edition, by Nicolas Collins enters the picture. There is a large section on combining LEDs and photo resistors, and using them to control all sorts of stuff. Sort of a "roll your own" vactrol. He also goes into triggering the led with a peizo driver. Electret mic elements are covered, along with pseudo analog to digital conversion for processing, then back to analog. I am hard pressed to tell you all the ideas this book opened me up to. Most of you probably already know most of this info. I knew some, but the way the book is laid out covers so many ideas it"s hard to describe.
