Hi there- I am an artists, musician and half way closeted electronics wannabe. But I need some help. I am designing an art installation for a window and I am trying to figure out a simple circuit that would allow people to tap on the glass and by doing so turn on (and then off) a relay or mosfet or something that would drive say 250-500 millampes, basically a bunch of led's.
Ill probably have to make 20 different circuits so I would like to keep the price down. I think in principle I could use piezos on the inside of the glass attached to some kind of FET into a flipflop cicuit, into a relay... but it is a little over my head. I can follow directions well though! if you have any advice. or can point to some specific designs.
Also I am aware that there will inevitably be some noise from ajecent tapping and the like- but thats fine- a dirty signal will be okay and make it more organic and random- just looking for a little added interactivity. okay please respond and Ill be psyched! if any one can walk me through this I can send them some art or music in trade- look me up www.mudboymusic.com
