The 4017 IC is CMOS, and therefore sensitive to static electricity! Any single-pole, single-throw switch is adequate. A household light switch will work fine, and is readily available at any hardware store. The audio detector will be used to assess signal frequency. Lessons In Electric Circuits, Volume 4, chapter 3: "Logic Gates" Lessons In Electric Circuits, Volume 4, chapter 4: "Switches" Lessons In Electric Circuits, Volume 4, chapter 11: "Counters" The model 4017 integrated circuit is a CMOS counter with ten output terminals.
A final lesson that may be learned from this circuit is that of switch contact "bounce. " Ana-R.url. Backstage - Circuit bending - ARTE.url. #Psychovinyle #Trackshare #Replay.

Legend has it that a young woman hot-rodded a tube radio and put on Vaudeville style noise shows in the mid-west around 1933. Is she still living among us? Read all about it on my ReGurgiTron site...

Towards the start of Autumn 2000, I was idly searching the www for experimental sound/music stuff.
I chanced upon an article by Reed Ghazala, who explained the strange art of 'Circuit Bending'. This is basically a process by which anyone can make bizzare alien electronic musical instruments! The procedure is essentially to take apart any battery-powered (low voltage!) Electronic sound producing toy and indescriminitely short-circuit it while it makes it's sounds. When you hear an interesting change in the sound, you mark the connection you made and later solder a switch or other component to the circuitboard.
