Hi All,
I'm sure there was a therad on these a while back but I can't find it.
Does anyone have some into on this technique, where you can stick a few pads on both sides of the PCB, attached to some kind of decoder, and sticking your finger in proximity to the pad activates a momentary switch. Something to do with the pads forming a capacitor and the finger affecting the electric field between them?
Could any kind person point me in the right direction here?
Cheers
