You could just get an adapter that is rated for a lower voltage. Try a nine volt adapter or a universal one that you can experiment with. -Fred -- This message was composed using Articulate Systems' PowerSecretary. Please forgive any sloppiness in (...)

I've managed to stick a wire onto a point in my battery pack which yields 6V. (temporary solution, at least...) However, the charger board doesn't seem to like this new arrangement much. With the lower battery voltage, too much current is flowing (...) (29 years ago, 11-Feb-96, to lugnet.robotics.handyboard)

I'm currently trying to get 6V out of my 9.6V battery pack. (I actually looked around for a 6V one, but couldn't find one that would work...) I've opened up the pack, and can access the cell where I can get 6V. However, I'm not sure how to get a (...) (29 years ago, 11-Feb-96, to lugnet.robotics.handyboard)

Thx to the advice of many of you I am using encoders from mice as shaft encoders. The code in the libraries does not seem to take into account encoders with TTL signal in quadrature.

OK, OK. RTFM, I know. I looked at the on-line manual, and now realize that IC arrays are different than normal C arrays, and so you can't do stuff like int m() { int *address; address=&a0; address++; } But then the question still remains, how can I (...)

OK all of you IC gurus. How come I can't do this: int m() { int *address; address=&a0; address++; } a0 is a variable defined in an .icb file. I also can't do something like address=address+2; or address[4]=7; Why not? This is all pretty standard C (...) (29 years ago, 8-Feb-96, to lugnet.robotics.handyboard)

While there is some discussion on robot bases, let me add a bit about the "third wheel", usually a caster, used on differential drive systems. Casters have the advantage that they are plentiful, cheap, and come in lots of sizes and configurations. (...) (29 years ago, 7-Feb-96, to lugnet.robotics.handyboard)

(...) I'd use 6V instead of the 9.6V main power supply - connect it where the main battery terminals are. It'd be really nice if the handy board had a way to use voltages other than 9.6V for the motor driver chips, ya know. :-) (29 years ago, 7-Feb-96, to lugnet.robotics.handyboard)
