Should I modify the hb circuit to disable the recharge circuitry if I am using nimh batteries or will the circuitry just not recharge the batteries ?, i.e. no damage to the cells by using them on an 'as-is' board. As an extra question to the list in (...) (24 years ago, 19-Sep-00, to lugnet.robotics.handyboard)

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 (...)

I am currently using nickel hydride AA cells in two 4-cell battery boxes and so far during my construction and testing of the board they have not needed recharging yet. I didn't have access to a mains power supply most of the time, so after checking (...) (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. I did this to eliminate motor RF interference to the (...) (24 years ago, 19-Sep-00, to lugnet.robotics.handyboard)

Hi, Quick question. How much runtime are you getting with your Handyboard based robot? With sonar /IRPD pinging once per second and my sensor array being controlled by two servos and my Lego motors pushing the 6 wheel drive rover I am getting 2Hrs. (...)

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 (...)
