Can i make a touch sensitive button? Answered
im working on a project that needs a non-tactile button switch. mainly because i am rebuilding the shell and the original button design wont work anymore. there isnt enough space for a tactile switch so i need somthing that can see when i am touching the surface, but it needs to be a rather simple circuit since i dont have a very good access to ICs.
if it helps any, the button has a metallic paint that is conductive, and there is a part beside it with the same paint.
is there any kind of circuit i can build that allows me to make use of that metallic paint and use it like its a tact switch?
any help is appreciated, i do have a 555, a couple L/R audio op amps and a NAND gate.
