I made a adb-to-usb adapter for my AEK2 using a teensy 2.0 and a cut up s-video cable. The TMK and QMK firmware have this functionality, but I used this firmware because it's much smaller and not a "kitchen sink" keyboard firmware:

Unfortunately it's US-ANSI only so my pile of 4 french canadian AEK2s don't work very well with it.
