i'm not sure if wiring two nicad packs in parallel is a good idea. the packs would fight each other if either one's voltage varied even slightly from the other. i'd recommend either (1) John's initial suggestion of adding a separate pack solely for (...)

(...) The Motorola reference manual (cpu12rm.pdf at motorola-site) of the 68hc12 (successor of 6811) section 9 has a practical approach to fuzzy logic. The special 68hc12 instructions are easy to implement in 68hc11 code. ntk. (24 years ago, 19-Sep-00, to lugnet.robotics.handyboard)

Jerry, I really haven't timed how long a battery charge lasts on the Handyboard but I did add a second 9.6v battery pack for the purpose of isolating the motor power from the logic circuit power.

You are going to find that it is not the encoders as I thought also. The HB seems to be incapable of reading correctly. I don't know why, but I have been trying for about 3 months with no/or little success. Someone knows, but no one is telling. I (...) (24 years ago, 18-Sep-00, to lugnet.robotics.handyboard)

I am working in adapting a PNI compass to the handyboard. And I have a 6500 sonar board connected to the expansion board, here's my idea: Use a Lithium 3.6V battery to save calibration settings after poweroff M/S is jumper selectable Calibrate is (...)
