You know I had to have one: http://www.ebay.com/itm/TTP226-8-Channel-Digital-Touch-Capacitive-Touch-Switch-Sensor-Module-HM-/181431842079

Lots of other interesting sensors on that page, too.

    That might mean you owe $27 to the twins' college fund, I'll have to review my policy... :)

    Great price, but why on earth are the touch pads on the same side as the components? So much for a panel/flush style mount.

    Good point. Also, I'd make a few other changes. Number the touchpads properly, left to right and top to bottom. Also, move the LEDs to right by their corresponding touchpads.

    My review. Neat little module is better for small fingers. Each pad is ~3/8" square, so it's easy to trigger adjacent buttons. Andy, just use the back side for flush mounting.
