David,

I would be interested in seeing a schematic on the wiring of the diode
array.  I am not sure of how it goes - exactly.  I'm not located near
a dedicated fax.  I was wondering if it might not be too much trouble
to sketch the schemtic on some simple paint software and mail the bmp.
I would really appreciate this - Thanks.

Adam, I think David meant something like this: |---|<|---|<|---|<|---| M+ ----x x----(motor)---- |---|>|---|>|---|>|---| | | M- ---...--- That way you have a voltage drop AND conduction in both directions. - Prabal (...) (30 years ago, 2-Mar-97, to lugnet.robotics.handyboard)

Hi, This is in response to the question about motor voltages posted earlier tonight. Check out the archives. Late last week I posted a similar question and got some good responses about wiring the HB for two power supplies and using diodes. I have (...)
