A board to fit tinyduino with stepper motors - tinyduino idea 5! Driving stepper motors usually requires either extra load on the CPU or an external drive board, so a board to drive 2 or more stepper motors directly would be very practical.

Again with the robotics!

Um, you can drive up to 8 servo's directly from the TinyDuino. 

Take a look at my Robot Ears, They have 4 servos driving all at once:

Of course, this uses up 4 of the digital I/O lines   We have talked about making a servo driver shield, so one is in the works.
