Hi, I've built several robots over the years and for the RoboExpo in SF I put together a web page with pictures showing them off. Most are R/C conversions but you can view them at (URL) happy to answer questions as well. All except the last one use (...) (28 years ago, 10-Aug-98, to lugnet.robotics.handyboard)

That may be fine, I'm not really very well versed electronically but when doing something similar I had worried that a resistor would reduce the voltage. That might be ok in this situation. Joe Martin (...) (28 years ago, 10-Aug-98, to lugnet.robotics.handyboard)

(...) You might want to try using a "bus" mouse rather than a "serial" mouse (assuming they still make them). They use to be quite common on PC's that had an ISA bus. On a "bus" mouse, all of the encoder outputs are brought out to a board that plugs (...) (28 years ago, 9-Aug-98, to lugnet.robotics.handyboard)

National Semiconductor make an "LM317" 3 terminal adjustable regulator which can easily be used as a current limiter. I am not sure if the schematic for this particular application is included with the Data sheets so I'll add it here. Current (...) (28 years ago, 9-Aug-98, to lugnet.robotics.handyboard)

I have 2 large motors that draw about 2 amps. They are powered by a battery that's 6v at 2amp. How can I limit the motors so that they can only draw 1/2 amp????? I know on my first robot (ahh, fine memories of burning resistors), I just made a bank (...) (28 years ago, 9-Aug-98, to lugnet.robotics.handyboard)

All: I am trying to find a World Scale RC Car/Truck base for my robot. One of the items I have been looking at was the Thunder King RC Monster Truck from MRC/Tower Hobbies, but they have recently discontinued that part. Does anyone have any (...)
