My problem is in running downloader. I am supplying power directly to the board but all that it displays is top row of black boxes which are kind of faded. Then I run the downloader program and it says it worked but the welcome message doesn't come (...) (25 years ago, 10-Feb-00, to lugnet.robotics.handyboard)

Hey, Handy Board people! I don't know if anybody has noticed, but this group is dead, dead, dead! It's time to get things going. Maybe people have some neat projects going on to tell us about. I have a robot I'm working on that you can read about on (...) (25 years ago, 9-Feb-00, to lugnet.robotics.handyboard)

I suppose that maybe your NiCd cells are just nearing the end of their useful life. Either that, or you have a wiring problem somewhere in the power circuit. Also, it's generally not a good idea to mix different types of cells (different capacities) (...) (25 years ago, 7-Feb-00, to lugnet.robotics.handyboard)

Its sound like your motor is drawing excessive current, thus resetting your Handy Board. You might want to beef up to a higher capacity battery or you can try running your servos off an external power source. Good Luck. (25 years ago, 7-Feb-00, to lugnet.robotics.handyboard)

It sounds like you might have a mechanical, rather than electrical, problem. Servos typically have some sort of stop nub on the gears so that they can't rotate past a certain point. If you don't cut off the nub with a hobby knife or saw, the motor (...) (25 years ago, 5-Feb-00, to lugnet.robotics.handyboard)

(...) Knudsen in his book (p 223) uses Digi-Key part number DN6847SE-ND, which, he says, is "sticky" in the sense that it remains set until explicitly reset. I have no experience with it. (25 years ago, 4-Feb-00, to lugnet.robotics.handyboard)
