Off topic, but I couldn't resist.  A neat circuit for debouncing a switch 
using 1/6 of a CD4010 chip can be found in Electronotes #73, page 11.  It 
is a simple positive feedback loop using a single 1K resistor from the 
output back to the input.  The switch is SPDT between gound and Vcc.  No 
capacitor is needed.  It acts as a latch.  Any CMOS gate (two inverters for 
example) would work.  Something to keep in mind for your next DIY circuit :-).
