PARTS: CD4049 RCA intigrated circuit .1 uF disk capacitor 1 uF 16V electrolitic capacitor 1K resistor 10K resistor 1meg pot 1N914 diode some SPST momentary pushbutton switches 9 Volt battery & clip and miscalanious shit you should have laying around the house.

You can link them together in a chain, etc. | ___ | | o o | | /\/\/\___| |__| | ^ | |____| ___ | | o o | | /\/\/\___| |__| | ^ | |__| | ! ! : (etc) : There are many other good mods to make to the box so have phun and be smart.
