More specifically: reverse engineering the UV-3R and UV-5R. Apparently it's pretty easy to reprogram the 3R's microcontroller, and they're both based on an I2C-controlled single-chip transceiver, so are eminently suitable for rebuilding for other applications.

There's a pretty spectacular demo of rewinding a transformer using a stepper motor to distribute the windings evenly -- and some other neat things, e.g. building a boost converted using an AVR, and measuring AA cell discharge rates.
