Traced out the circuit connections for the numpad. So now I have a pinout for wiring the buttons up.
Also gave the layout a try on the perfboard, gonna need to raise the face buttons up some to get them level with the microswitches.
Update:
Got the actual wiring figured out for the buttons. Tact switches are surface mount, so gonna have to figure something out for extending the pins below the perfboard. Threw together some standoffs made out of paper clips to keep everything from shorting.
The lines between the buttons represent common pins. Red is the pin number on the left, and black is the number on the right.
Tomorrow I should be able to start on soldering things, and give my button idea a try.
Update:
Scavenged some wire from one of the mice I took the buttons from :D
