Additionally, I'd like to do something with the LEDs in the keyboards for the shift lights, until then, it's done.
Step 1: Gather parts
I used the scanner from an all-in-one printer. Find something about the length of a keyboard.
My only disclaimer as far as gathering parts go, some older keyboards may be worth a good bit. Look up what you have before you gut it. A quick Google search might surprise you. A side note, it will be harder to use boards made prior to the 2000's, just because of how they are built.
