Yes, this could absolutely be used to make an Arduinome. I think the usual Arduinome design is 8x8 but I'm sure it wouldn't be difficult to modify the code. And that is an interesting idea about making the holes larger. You'd have to change the switch wire arrangement because there isn't much tolerance for error in the current one, but I think I'd use a different switch design if I made it again anyway - if you make the wires run horizontally and vertically and make the switches where the wires cross over, it would be easier to press every switch in a row or a column just by sliding your finger along that wire. It also wouldn't solve the problem of avoiding kinks in the wire unless you switched to multi-stranded wire at the same time. And you'd have to choose the sizes of the holes very carefully to avoid making the screen too fragile.

I love this idea, absolutely brilliant.

Though I am just starting to learn electronics (I have cobbled together a bliptronome and some arduino projects so far), I am wondering whether this screen/led/multiplexer combination could work to make a Arduinome.

What do you think?

Also, I am wondering if would it make it easier to thread the wire through the screen by making the holes substantially larger than the diameter of the wire? Then one could put a little bit of hot glue in each hole after the wire has been threaded through in order to stabilize the situation. What do you think?

Thanks, Malik

This is a nice project: economically-minded, with a strong follow-through. Many people would have stopped after getting the capacitive matrix working. It also turns out that you're a skilled assembly programmer! We should talk more, because I'm a synthesizer algorithm programmer. I do most of my work on AVR microcontrollers, too. That's why I'm glad you've included useful optimization tips for gcc. If you or anyone else who likes this project is curious, I'm working with QTC senors, and a six-string guitar algorithm over at http://exertion.pbworks.com
