Hi,
I am using DC Motors for the first time (previously used stepper motors) and
have been experiencing difficulties when first powering on the handyboard.
When I first turn on the power, occasionally the motors start up at full
speed for no apparent reason. This happens about every third time I power
on.
I am wondering if this is caused by some kind of motor/handyboard
interference, and if putting a filter cap across the leads of the motors
will help. (and if so, what size/type of capacitor?)
Can anybody help me shed some light on this? it's really causing some
problems, as I am using plastic gears and they tend to break at full
throttle.
Thanks,
-patrick

| (...) [snip] (...) Bingo. Put .1uf caps (rated at least 4X your max voltage) from the (+) pole to the can, from the (-) pole to the can and from the (+) to the (-) pole. Keep your leads as short as possible. Put a big cap (1000uf+) on the power (...) (25 years ago, 14-Apr-00, to lugnet.robotics.handyboard)
