Hi Malc,

I Had my father home this week-end ...

We talked about supplies and it seems the today's "must" is to use switching supply during speed transitions ( or accelerations ) and DC during constant speed running ( of course for noize !!! ) ...

That meets one of Sougata's threads about signal generation with a Pic ... and opens interesting reflexion and work about what output stage to use !!!

new challenge for Darrel !!! ( He Looooooves !!!! )
