I'm hoping someone can help me figure out the problem with the following driver. Ultimately I want to simulate a sony IR remote control using a 6.270 board. I acquired the sony-ir.asm and tried it out, but that wasn't working; so I trimmed it down (...) (25 years ago, 17-Jan-00, to lugnet.robotics.handyboard)

Mark -- I built a chassis for my robot that cradles the HB and clamps two Lego gear motors solidly in place. Check out this web page for photos: (URL) side of the chassis consists of two sixteen-unit beams, one on top of the other with two-unit (...) (25 years ago, 17-Jan-00, to lugnet.robotics.handyboard)

I've mentioned this subject before here, but I never really got an answer that made much sense... Has anybody ever tried building a reasonable "LEGO-ish" container for the Handyboard? Ideally, that would be a sturdy enclosure that still provides (...) (25 years ago, 15-Jan-00, to lugnet.robotics.handyboard)

I read on this list over a year ago that you *can* piggyback the two different chips together and still get the spike protection from the L293D. It was explained that you don't need to piggyback two L293D chips, because one spike-protecting chip (...) (25 years ago, 15-Jan-00, to lugnet.robotics.handyboard)

(...) Sorry for two messages about the same subject but after playing around a bit more with it I got better results. Here is the spreadsheet to calculate the constants to convert the GP2D02 output to centimeters: 0.1233 1.0320 9.3078 GP2D02 Actual (...) (25 years ago, 15-Jan-00, to lugnet.robotics.handyboard)

(...) Actually, the GP2DO2's output is not at all linear. Plotting the output against the actual distance will show an exponential curve. Each one is slightly different so what I do is to make up a little table in Excel like: 0,0 70,10 116,15 142,20 (...) (25 years ago, 14-Jan-00, to lugnet.robotics.handyboard)

| | Using a 293B/293D combination
|

The HB FAQ mentions using the LM293B and LM293D chips in parallel (e.g., one L293D and one L293B) to gain increased current-carrying capability. My question is, if I do this am I losing the function of the spike-protecting diodes on the motor (...) (25 years ago, 14-Jan-00, to lugnet.robotics.handyboard)
