Earlier this year, about June, I bought two of these keys, mounted on a plate (
link), thinking I could make myself a little gamepad or separated keyboard. I never got around to making a PCB or even spaghetti-wiring the thing up for testing.
Now, heading into the new year, I would like to get this started in the least... so I have a few questions:
* If keyboards use solid X,Y lines, how does the controller know which key has been pressed?
* How do I make a PCB for this unit and where would the cheapest 1.6mm prototyping PCB maker be?
