Hi,
  I've just been looking at <http://www.bytecraft.com/touchsw.html> - has
anyone tried out the circuit on that page? Does it work?
  Even better - does anyone know if there's a way to reduce the number of I/O
lines in a similar way to a matrix of pushbuttons? I want something small,
with at least 12 keys, hooked up to a 16F628A (eventually). The whole
device - including the 3x4 keypad array - is going to be around the size of a
credit card.
  Am I stuck with normal mechanical switches?

Thanks.
