So I'm reading on the Raspberry Pi project, and it seems to have some desirable features:
1) Runs a full Linux stack
2) Costs USD 25 when it finally releases
3) has about sixteen digital I/O lines
I'd think 1) would give you a lot of flexibility, and 2) makes it cost-competitive with an Aikon-style job, but 3) might be a bit short for the job. The regular AIKON has 26 I/O lines to the keyboard matrix, no?
I could see some sort of breakout box to address the rows and columns on a subset of the 16 GPIOs, but that would make programming more complex and reduce the cute and tidy factor.
OTOH, it might also be awesome built into a keyboard in a C64 style-- either use the board directly as a computer, or use it to emulate USB devices
Maybe one line for a "Row enable", one for "Column enable", and four lines fed to two demultiplexers (one for columns, one for rows) to give a 16x16 matrix on a six wire bus, but my CS110 is a bit faded...

Price is right, but overpowered much?

Yo dawg, we heard you like computers. So we put a computer in your keyboard so you can type on your computer while typing on a computer.

I was thinking about doing the C64 thing with a raspberrypi myself. Looks promising.
-
Way overpowered. There are plans for an expansion board for it, with lots of more GPIO lines.
-
I promised myself that i buy one. Thinking of buying few and making cool cases and some mods to them :) Keyboard idea is pretty neat!
-
Just buy my AIKON once I have it done. Unless you had other ideas for the adapter besides the AIKON's capabilities.

I was going to buy one for a TV box, but a keyboard mod in which you use it for more than JUST a controller could be pretty sweet.
