I posted specific questions concerned running IC on windows 2000 last fall. I had a variety of problems. My solution was finally to use old machines with DOS or old windows. I am interested in any successes people have had with running IC under (...) (23 years ago, 24-Jul-01, to lugnet.robotics.handyboard)

Hi Jan, I can not help with this specific device, but are you sure the device works like this? Can different outputs be measured, depending if there is white or black in front of it? Here I mean: measured with a voltmeter when pin 3 is not connected (...) (23 years ago, 18-Jul-01, to lugnet.robotics.handyboard)

Hi All, Does anyone in this group have experience with using the KMZ10B (magnetic field sensor) to build a shaft encoder? I am interested in a schema to connect it to the HB, either digital or analog input. Thanks, Willem (23 years ago, 17-Jul-01, to lugnet.robotics.handyboard)

Hi All, Thanks for the good advice I got. I applied a separate power sypply to the board, to drive the motors and everything seems to go well now. I am not sure if I need to change the L293D for a more powerfull alternative. The chip driving both (...) (23 years ago, 14-Jul-01, to lugnet.robotics.handyboard)

Nichola's suggestion is a simple and raw method to supply enough current for the motors, but it seems difficult to imply if your handyboard has an expansion board attached... The height between the two boards is not enough to fit 2 ICs, and this (...) (23 years ago, 11-Jul-01, to lugnet.robotics.handyboard)

I think your trouble come from the H-bridge chip (L293D), it doesn't support more than 600mA of current draw, and reset or crash the board then this value isn't respected. To solve this trouble, I used instead the L298N, it support up to 1A. In (...) (23 years ago, 9-Jul-01, to lugnet.robotics.handyboard)

Hi All, I Just created a (my first) mobile bot with two motors using differential drive. At random moments, during motor activity, one of the motors (or both) seems to go wild and soon after that the BATT led blinks and then the board is reset. I (...)
