Aha, I know nothing about Handyboards, only about NiCads. I don't see why you need a larger power supply to charge slightly larger cells. Your handyboard is probably only drawing about 75 to 100 mAh to charge at 50 mAh, so a bigger power supply (...) (23 years ago, 10-Apr-02, to lugnet.robotics.handyboard)

I'm sorry, I didn't explain myself well enough. I meant to say that I used the 500mA 12V power supply (block AC to DC transformer) by connecting it to the handyboard. From the specifications, the handyboard is supposed to be able to charge 800mAh (...) (23 years ago, 9-Apr-02, to lugnet.robotics.handyboard)

Interesting this is being discussed now. I wrote a chunk of code at the weekend (NQC) to allow me fine control over the motors. Basically, you give each one a number from 0-100, call it N. The drive task counts ticks from 0-99 and ensures the motor (...) (23 years ago, 9-Apr-02, to lugnet.robotics)

Jeremy, You hooked it straight to a 12V power supply? That's kind of a brutal way to charge NiCad's. Who knows what that's going to do. If it's regulated at 500mA, then it should take just a little over two hours to charge a 1000mAh pack, which is a (...) (23 years ago, 9-Apr-02, to lugnet.robotics.handyboard)
