Yes alot of it will go to some robot club, I am still snapping pictures and
trying to add more of the larger stuff. A goal may be a light plasma cutter
or router. I guess you look for voltages above 24, maybe 60+.

Yes it is, about all I have done is insure the existing driver and motor
work by massaging the inputs to the MPU and I have found that the translator
is always needed since the processor does the timing. I guess I will still
need to build up a board. I normally take parts out if usable to a point.

About all the room I have in my 8 x 16 hole.

I think it was a large hard disk, but I really can't remember to be sure, it
gets a lot of attention.
