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 9V motors that I am running at 6V by using an array of
diodes (3 or 4 in series) between the motor output and the motor. But, if you
want a bidirectional motor, you must wire a fork into one lead and use two
arrays, one pointing opposite the other, and then recombine the lines into the
one lead from which they came. This has been effective for me and has not
required any modifications to the HB. 4000 series diodes can handle 1A of
current, maybe they will work for you. If the circuit I described isn't clear
to you, let me know and I can fax you a schematic.

| 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 (...) (28 years ago, 2-Mar-97, to lugnet.robotics.handyboard)
