Turntable functionality is essentially complete; the firmware is super basic and only uses "direction" and "number of steps" as input. Will add (messy) arduino code.
Hardware I used:
sparkfun NEMA 17 stepper motor
sparkfun hub spacer
sparkfun Big Easy Driver
sparkfun teensy 2.0++ (any arduino compatible board with digital pins should be fine)
amazon 12" lazy susan

Here is arduino code: teensy_turntable.ino
It's pretty ugly, and probably hard to interpret without some sort of reference pictures. Including it for completeness even though it's essentially useless for now. Eventually I plan to write a basic tutorial in wiki about this; if only there were a cheap usb powered one available off the shelf.

hmm that seems like a lot of code. I might take a stab at it. it doesnt look like you are using software serial connection to communicate?

can't advise messing around with it too much since it will probably just give headache ;)
Correct on not serial; rather than serial I chose USB HID which allows reliable identification of device by vendor id etc. more info @ https://www.pjrc.com/teensy/rawhid.html
