I just tested a PS\2 Keyboard with the circuit I posted yesterday, and it works perfectly.  Now I just need to hook up the PS1 controller, write the program, test it out, then cram it all in the PS1 Controller!

Below is a vid of the PICAXE debug screen which shows that the keyboard is working.

I wrote the program for PICAXE. Kupid is no longer just an idea, or a proof-of concept. Kupid LIVES! See the latest vid here: http://www.ustream.tv/channel/kupid-testing

I have caps-Lock working. Just press the caps-lock key on your keyboard, and the caps-lock light will turn on or off, indicating to you whether or not you have caps-lock on.

I am still working on the special symbols & characters. But should have the entire program complete shortly. UPDATE: Special characters & symbols are now working.  Just press either shift key (don’t hold it down), then the “num-lock” light on your keyboard will light up, and then you just type in whatever special character you need.  Also, F1 through F5 type in the special symbols (male symbol, smiley face, heart, etc).

Due to memory limitations, as I feared, I won’t be able to get that copy/paste function working. It’s doable with the addition of a 4KB EEPROM, but that would raise the price and mean a lot more work for me. So I’m just going to focus on making the core Kupid unit.

The program is now complete.  All I need to do now is get everything crammed inside the PS1 controller.  It may take me a little bit to figure it all out, but I’ll post updates as soon as I make progress.
