What would you like to know? I plan to use this base on top of a rear projection multi touch screen, hence the led underneath. and the rest of the piece is as stated. I would think a coin type / watch battery could be used as the power source, and when I touch the base it lights up. a momentary capacitive sensor attached to the base that would create a complete loop, and when let go the loop is broken, but I have NO idea about what the components need to be. What should the actual amperage and voltage of the power source be, what resistors or capacitors and the like. If I could get the short list of: this capacitor, with that led, and that battery etc, I can figure out the installation design. Hope this helped and let me know if I can offer anymore,.. I really appreciate the help guys,...
