Question about creating a custom keyboard
So I went and bought a $10 keyboard and took it apart. Then I went through and figured out what key creates a short between which 2 (or more) pins.
I plugged the PCB into the PS/2 port, and the computer sees it as a keyboard, so no problem there, but when I try to short two pins together with a wire, it does nothing.
Am I missing something on how keyboards work? The only reasons I can think of as to why it wouldn't work is because A) I need to use a momentary switch and not a wire and/or B) the piece of wire wire (18 guage) has too high of a resistance (~1 ohm) and of the .5uA I measured not enough can get through.
So for those of you who hacked a keyboard and wired it up yourself, whaddya' know that I don't?
You nailed it right on the nose....
and that would be the kicker. I must've had one side of the wire in between two of the traces because after reading the first reply I went back and tried again and TADA! Worked like a charm.

I would just check to make sure your shorting 2 pins that actually do something.
Now I'm just trying to figure out what's the best way to hook the PCB up to the switches. I was thinking that I might try using a connector instead of soldering wires straight to the board so that if I need to expand what keys I'm doing later it would be a little easier.
