Hi, My homebrew quad hall effect encoder works, I'm learning from it. I get @ 1/4" resolution so there's plenty of slop. I can have the robot pace back and forth on a straight track for 6 passes or so then I start to veer off track. So I guess it's (...) (24 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

Hi everyone. Well I decided to go with a Quad Hall Effect encoder. I mounted 4 very small magnets on my 1" plastic drive gears and used the Hall Effect switch that Fred recommended. Here's the code I have and the results! For a 180 degree turn I get (...) (24 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

|

hi. you can certainly tap the 9.6v batt output to power the sensor (use J13), but make *sure* that the sensor does not put out more than 5v, or you'll blow your analog inputs. if you're not sure, put a 1K resistor in series with the sensor's output (...)

I have read the FAQ on cutting the trace that supplies motor power from the Handyboard battery so you can use another power source but it doesn't address the issue of what to do if you have an expansion board. I am sure someone must have done this (...) (24 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

Hi Everyone, I want to use a photoelectric sensor with my handy-board. The sensor require a 10 V supply voltage, while the digital inputs of the HB only supply 5 V. Can I simply use one of the motor outputs to supply the sensor, and plug the signal (...) (24 years ago, 8-Sep-00, to lugnet.robotics.handyboard)

Hi everyone! I guess it pays to be polite and explain why you need something! Well Newton Labs posted the pcode source back on the web server. If anyone owns an Interactive C 3.1 license and you want to work with the pcode source, it can be found (...) (24 years ago, 8-Sep-00, to lugnet.robotics.handyboard)

Hi Everyone. I am working on aquiring the source to pcode_hb.asm. I pointed them to the newsgroup posting that has Randy Seargent himself directing someone to download the pcode source from newton labs. I also informed him that if I am going to (...)

Whew. I have encountered the same problem back when I wanted the improved PWM code in the new version of IC. Back then (about 2 years ago) I managed to find someone who actually had a copy of the 3.1 pcode. Don't ask me for it, I lost it long ago. (...)
