Hi all

I've got a mini drill powered by a 12V transformer. Problem is that it is an On/Off drill, no variation in the power applied to it.
I'm looking for leads on what to look for in order to build an electronic variator system.
I already know about variable voltage regulators, but they dissipate the difference into heat, which is not really desirable.
Any help greatly appreciated

Cheers
Olivier


AC or DC ? 

DC, +12V
