Re: SV: SSRs, relays, speed controls

Yep, Bob Blick's code runs at ~20mhz and generates 
the PWM outputs inline instead of using the PWM 
modules in the PIC.  That setup requires 4 SSRs.  
That would still be over $200 wholesale to implement 
when dealing with high currents.  I'm sure it works 
good though.

Someone just needs to find us a source of free high-
current solid state relays...
