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)

Overcharged NiCd Batteries? Hello, I recently built a handyboard and bought a set of 8 1000mAh NiCd batteries for it. I charged the batteries using the handyboard and a 12V 500mA DC adapter from radio shack. I only charged the batteries for (...) (23 years ago, 9-Apr-02, to lugnet.robotics.handyboard)

I’ve never had any problems with the light sensor reading fast enough, and I have a robot that runs pretty fast. How are you trying to follow the line?
