I did a little more playin last nite with the Simtek mem chips. Whether or not the Mem chips will save memory depends on a few things. If I am powering the HB with the serial/charger line and unplug it, the Simtek chips will hold their memory. If I (...) (26 years ago, 24-Mar-99, to lugnet.robotics.handyboard)

I'm using win98 an ICC11. I was unable to get ICC11 to communicate with my handybaord. I instead used hbdl to download the output (s19 file) from ICC11 to my handyboard. This worked without problems. My biggest problem was that in my project I (...) (26 years ago, 23-Mar-99, to lugnet.robotics.handyboard)

Just a suggestion but you could mount a Hall effect sensor somewhere near a rotating rounded part on the cage and glue a small piece of magnet to the rounded part. You could look for the pulse on a digital input. This way it would not add much (...) (26 years ago, 22-Mar-99, to lugnet.robotics.handyboard)
