The LiniStepper is a partial project. Roman Black got the idea, did
his project and then moved on. It is not really polished and has old
technology (transistors) for today.

Also, it is really limited to about 1 amp max with large heatsinks.

Great for high voltage, low current motors from floppies and such.

Someday, someone will really take the time to get into the unit and
fix the circuit and polish it quite a bit.
