Hi All, This problem has been addressed many times before, but I have yet to find a solution. I have come accross a handyboard that has been sitting around for a while, and I decided to refresh its internal program. To do this I have tried all of (...)

First, I am new to this newsgroup, so hello everybody! Second, I was just curious about how many of you (meaning people on this list) are building or have built robots for the Trinity College Fire Fighting Contest? Especially if you made one for the (...) (23 years ago, 1-Mar-01, to lugnet.robotics.handyboard)

"It's a primitive" means that it's defined in the machine code, in the runtime engine. You can look through the source to pcode.asm to see how stuff works... (URL) . Fred In your message you said: (...) (23 years ago, 28-Feb-01, to lugnet.robotics.handyboard)

I'm trying to locate the actual code that comprises mseconds(), but all I can find is a statement saying that mseconds is now an IC primitive. Is there anyway someone can direct me to that code? Thanks in advance (23 years ago, 28-Feb-01, to lugnet.robotics.handyboard)

Hi all: I've modified the HandyBoard by cutting the PCB trace as detailed at (URL) and I have a couple of questions before I destroy something. I'm connecting two 1500mAh 7.2V NiCd batteries in series to the 4-pin motor power header, and I'll be (...) (23 years ago, 27-Feb-01, to lugnet.robotics.handyboard)

Rob, a few Q's: 1. Can you verify that +9v is being applied to the sensor by transistor Q2. Measure the voltage at the collector, you should see a pulsed waveform (rectangular wave) with +9v on's and 0v off's. (Refer to (URL) What is the (...)

This is a follow up to my original question about the rotation sensor. When we hooked the sensor up to the oscilloscpe and the Handy Board, we could see the voltage transitions on the scope. Now, we truned the sensor very slow (about 2 ticks per (...) (23 years ago, 27-Feb-01, to lugnet.robotics.handyboard)
