Thanks Tom,
I replied to your email. I wold love to have you send me a schematic. We can make
our own boards but my strength lies on the machancal side. Should not be a problem
and a good exercise for the students. I'll also search ouy the master 5 site. Again
thanks for your guidance and willingness to help.
