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)

(...) Yes, I just recently did some timing tests, using that exact method. Each bytecode takes 2.9 +/- .2 ms to execute, as near as I can tell. This appears to be independent of which bytecode it is (though I did not test any that I really expected (...) (23 years ago, 9-Apr-02, to lugnet.robotics)

I would like to sell a working handyboard to anyone interested. It works fine I just don't have time to play with it anymore. (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 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)
