Hi, I was playing with my handyboard's sonar.. The distance limitation is in the code, since we are using integers we are limited to -32,778 to 32,768.. and that's why I am at @15 ft limit. After we change the sonar code to longs the problem is (...) (26 years ago, 12-Sep-00, to lugnet.robotics.handyboard)

Hi everyone, Here's some code that I have so far. I have no clue why I only get 15' range out of my Polaroid 6500.

Hi, How do you get 35ft range out of the handyboard? I get a negetive number when hitting an object over 15ft away! Does anyone else have this problem? Can I adjust it somehow? Thanks! (26 years ago, 12-Sep-00, to lugnet.robotics.handyboard)

IC can't sample the A/D converters that quickly. As long as you're generating a nice squarewave you could connect it to one of the input capture pins and write a custom interrupt routine to maintain the count. --Chuck (...) (26 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

Since some are on the subject of encoders, I have a problem I would like to get help on. I have a hall effect sensor dutifully counting pulses on a gear. The gear will rotate from 800-4000 RPM. I am running the signal through a 741 OP Amp to (...) (26 years ago, 10-Sep-00, to lugnet.robotics.handyboard)

Jerry, go to: EE 401 - Electrical Engineering Design Course - 1999/2000 then to shaft encoders they have 16, 32, or 64 sections you can print out. bye, Terry G. ----- Original Message ----- From: "Jerry Normandin" <jerrynormandin@ne.m...iaone.net> (...)
