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 am posting this to the general robotics newsgroup (I hope) (...) The answer to this bit is easy - the RCX reads the sensors once every 3 mS under the Lego firmware. (I have no idea what the LegOS kernel does.) The purpose of this post however, is (...) (23 years ago, 9-Apr-02, to lugnet.robotics)

(...) I had a similar problem using RoboLab. I had a task that looped and checked the light sensor once in each loop. If the light sensor changed within the loop but NOT at the time when the check was made it would be missed. I replaced it with a (...) (23 years ago, 9-Apr-02, to lugnet.robotics.rcx.legos)

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? Maybe there’s a problem with your conversion between NQC and LegOS. I’d be glad to offer (...) (23 years ago, 9-Apr-02, to lugnet.robotics.rcx.legos)

I'm a new legos user and I'm trying to get my first app working. The issue appears to be that the light sensor value isn't getting updated as frequently as I expected. When I slow down the motors my line tracking program works fine. I speed it up (...) (23 years ago, 7-Apr-02, to lugnet.robotics.rcx.legos)
