Copper Box

This mod was sent to me by fellow bender and experimental musician Allerian, is called the Copper Box. The case supposely came from an old hand reciept machine. The control surface features four copper touch plates that are tied to the onboard oscillator circuitry changing the resistance levels when they are touched by skin thus effecting the oscillators. Copper happens to be the best conductor trailing only to silver, being far cheaper makies it a great choice. I tend to use just plain old screws with their tops sanded quite well to create a rought conductive surface. The conductivity depends on oil levels of your skin and can be improved by wetting the skin. Other things that are quite interesting to experiment with are flourecent lights and "plasma" lamps, the ones that have arcs of energy in them. Electrons get picked up by the contacts and turned into various noises. For some reason this mod reminds me of the Mars Rover, I dunno maybe its just me.

    Thanks for the writeup. Also worth noting on this project is the pull-chain power switch which can be seen here:

    One more comment. While wetting your skin does make body contacts more sensitive, the real controllability comes after you've done a load of hot soapy dishes.

    I noticed the power switch you had. Nice touch. This seems to be very much like the Crackle Box idea. I think it said on your site though that you used 555 instead of the 709 present in the C.B. I have not been able to find anyone near me that has the 709's but I have a heck of a lot 555's. Is there any Schematics or hints you could give us on building one of these CopperBoxes.
