| Guys, I caught the mail on motors (3V etc.) and wasn't impressed. I just bought one of those Bulldozer Kits from Tamiya and I believe it contains 3V motors. Is there NO possible way of using these motors??? I did notice the HB motor driver chip (...) (27 years ago, 15-Feb-97, to lugnet.robotics.handyboard)

| (...) 3v toy motors are noisy little buggers and were never designed to be anywhere near a microprocessor. if you reduced the hb motor battery supply to 3v, you might have a chance. at 9v, i really doubt it. -f (...) (27 years ago, 15-Feb-97, to lugnet.robotics.handyboard)

| (...) It has been my experience that it is easier to change the drive circuitry than it is to change the motors. The circuitry is just solder and chips, the motors are mechanical tooling. Driving the Tamiya BullDozer from the HB is certainly (...) (27 years ago, 18-Feb-97, to lugnet.robotics.handyboard)

| (...) Why not use the H-bridge that is already on the bulldozer? If you work backwards throught the motor driver circuitry, or use the RF controller to send commands to the dozer and see what voltages change you can figure out where the inputs to (...)

| (...) This is also excellent advice. On one R/C car I had, I ended up having to simulate the signal input to the controller because the h-bridge was so screwy but it does save you from having to build your own. On a related note, Radio Shack sells (...) (27 years ago, 19-Feb-97, to lugnet.robotics.handyboard)
