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)

There aren't user-adjustable thresholds in my Exp Board LEGO rotation sensor code. Rob, could it be that you are spinning the sensor too fast? In the docs there is a note that it only can deal with 16 rotations per sec. Fred In your message you (...) (23 years ago, 26-Feb-01, to lugnet.robotics.handyboard)

The advantage of distributed processing is that you can take a sometimes considerable load off the main MCU. Consider a speed regulator: a sensor is needed to continuously monitor the speed at which the wheels are turning and adjustments in motor (...)
