Hello again,
Thanks to all who responded to my query regarding motor chips on the
Mini Board. Now that I have the more capable motor drivers installed, I
want to lower the voltage that my motors see. They are getting straight
9V from the motor chips now, but they (and I) would be happier at 6V. I
have heard on this mailing list that there is a way to do this with a
diode array. Can anyone refer me to a schematic in a book or just
describe it well enough in ASCII?
Thanks,
David

| I (...) Use a couple power diodes in series with the motor power supply, _NOT_ the motor itself. You'll need pretty heafty diodes if you go this route. A typical Si diode drops between 0.6 and 0.7 volts when forward biased. String a few together and (...) (28 years ago, 23-Feb-97, to lugnet.robotics.handyboard)
