you should charge a lead acid battery which is between 10% and 90% charged at a rate of Capacity/10. In this case the rate would be 0.2 amps. when the battery is either almost charged (>90% charged) or almost depleted (<10% charged) the rate shoud (...)

You can write "Interactive C" (IC) programs on a PC/Mac and download it into the HB. IC is like C but alot less complicated. If you know C, it is pretty simple. If you don't know C, it is just simple. You can also write Assembler which is a little (...) (26 years ago, 5-May-98, to lugnet.robotics.handyboard)

The faster you switch, the more power will be lost to the switching of the power transistors and the filtering effect provided by the inductance of the motor. At the other extreme, frequencies (...)

I have a 266 G3 minitower, and I have the identical problem. The only way to solve this is to let IC die, not reset the HB and then run IC again. It complains to can't talk to the HB, and then I reset the HB and all works fine. Kinda odd, but it (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)
