Dear Piclisters, I like documenting my projects, so I borrow a friend's digital camera and take a few snapshots. For your interest, here is an amatuer project that added radio control to a toy train for a disabled child.

In fact, I wish there was more PICLIST traffic ... at the moment it's only half my daily mail load. How many amp hours in a typical alkaline C cell? This locomotive draws 400mA at full PWM.
