Re: relay and SSR mixer

Thanks Joe.  In between meetings yesterday I finished 
the math routines and PWM logic so I'm writing some 
of my own code as I have time today.  I've learned 
enough now to do mixed assembler & BASIC.  I like the 
challenge and those darn PICs are fun to play with...

With that, I haven't done any research into specs so 
what's the recommended FETs to handle ~40A if I 
decided to get sophisticated?

Regards,

Ted
