Fw: [CAD_CAM_EDM_DRO] Re: PWM vs Constant current and G-rex

Ron, I'd looked at the combo board on Mr. Chambell's site [ sound logic]
and had thought it was pretty pricy compared to other borads which do
pretty
much the same thing.. of course I was forgetting that this included power
supplies and a charge pump.. so after looking at it from that perspective..
I think it would end up cheaper.. plus its and all-in-one package so..
You'd still need power supplies for the Gecko's off downstream from this
though also.. won't you?
