Anthony, As you've no doubt heard, RC motors take much more current than the Handyboard can supply. To control RC motors your only choice is to create a separate H-bridge to drive the motors. You can do this fairly inexpensively with power (...) (27 years ago, 10-Nov-97, to lugnet.robotics.handyboard)

Hi Jeremy! I used the shaft encoder out of a track ball for my robotic project(same thing but a bit bigger). You do not need the IC out of the mouse just take the shaft encoder and use it with a IR led and detector pair. If you are going to use the (...)

Hello, RC car motors pull a lot of current, from 2A to 8A. The L293D chip goes up to 1A peak (for some miliseconds) before it shuts down. I suggest bypassing the L293D chips and using something like the LMD18200. (URL) Good luck, Marco A.A. de (...) (27 years ago, 10-Nov-97, to lugnet.robotics.handyboard)

Three of us are undertaking a project using the Handyboard as the control system for a class at MIT. Our project, an autonomous blimp, has an unusual set of constraints, but we're hoping that your collective experience might be able to help us (...)
