Re: [CAD_CAM_EDM_DRO] PCB design and manufacture

Alright, I am designing the card right now, but have a newbie question.. How
well do DC and AC interact?
I have 25-35x AC motors, and need to control them via the
parallel/serial/usb port, but I was planning on using some NPN transistors
as amps, with the base being DC and the amp power being the collector..
But for some reason I don't think this will work...

Any ideas?

thanks-lee
