I was lloking to buy a keypad but found that they are pretty expensive, not
less than 30-40$ and up ... So I was wondering, did any of you tried to make
your own ? I know you only need 16 switch N.O. and hook then like the matrix
in the keypad, but I was wondering if you guys had some ideas on how to make
it look good ?

If you already made one, please tell me what you did and what it looked like
(if you have some pictures...)

Old video recorders are a good source of components and construction
techniques. They almost invariably use little N.O. push switches behind the
front panel buttons. With a little care, a soldering iron, and a small flat
blade screwdriver they can be levered off the pcb and re-used.

Motors can be recycled into models, Inductors into transmitter and
receivers, crystals to PIC clocks. But I don't recommend recycling the
electrolytic capacitors, they tend to have a finite life.

Chris
