I am interested in creating capacitive touch switches to replace the wall switches in my house. I would like it to fit inside a standard switch box and work through a decorative (dielectric) material... Glass, Wood, Ceramic, Plastic, etc... so I can create custom looking switch panels. I have found a couple of commercial products but they are prohibitively expensive. I have also researched some common IC solutions like the Amtel QT100 or the AD7746 (offered by sparkfun) and this looks promising, but I would rather find a through hole chip rather than surface mount as I am not really equipped to work with SMT.
It would also need to be powered off the wall power. Does anyone have some guidance? I am surprised I have not found more about this as I would assume this would be popular alternative to the standard wall switch.
