Build or buy a nifty PWM hand held throttle

PWM control is great on DC layouts, particularly for yards and switching districts. It enables truly slow scale speed operation without hiccups or "instant" starts and stops.

This fellow sells a neat little hand held throttle that generates a PWM signal and gets its power for the AC outputs on your transformer. He also shows the complete schematic if you'd like to build it yourself.
