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)

(...) Yes, you're right. (...) Yes. (...) Me thinks 2x4 swiss cheese brick is not so bad after all. One thing I wonder is if anyone used them for bracing before the technic era. At that time my mechanical contraptions had a strong tendency to fall (...) (23 years ago, 9-Apr-02, to lugnet.robotics, lugnet.technic)

Here are some quick pics of the new gears: (URL) my apologies for the crappy photos... but I think you'll get the idea. There are some other parts of interest in the Bohrok sets that may be useful... especially if someone is trying to make circular (...) (23 years ago, 8-Apr-02, to lugnet.robotics)

The hardware can get a light sensor reading every 1 mS. Is the process that is reading the light sensor at a high enough priority?

(...) Why not just holes? That's what standard technic bricks call them. Though maybe it needs some indication that it has holes in 3 directions 8?) ROSCO (23 years ago, 9-Apr-02, to lugnet.robotics, lugnet.technic)
