Have you seen that "Make your own Printed Circuit board" kit at radio shack? I bought one years ago and you use a magic marker to draw the lines on the board, then you soak the board in the brown liquid for about and hour if i remeber correctly. and when you removed it, the liquid desolves the magic marker and leave the conductive tracing on the board and there you have it. well my question is, if i had a plexi glass lid and i mount a swith to it. could i draw the two lines (picture the lines being the two wires used to connect a switch) on the plexi and have it work like a printed circuit board?
