Thank you! Surprising that with as easy as it is to backdrive, that the
efficiency is as low as it is.
Out of (not idle) curiosity, is it possible to drive even more current-hungry
devices safely from the NXT? I need a way to drive a 120V AC, 15 amp device
under NXT control (I need to be able to cycle it on/off rapidly with a variable
duty cycle, to control average power output).
