Using the handyboard, can we drive a DC-motor which has a nominal voltage of 26 volt, (the starting current is less than 600mA). Thanx. Hachemi. (29 years ago, 2-Apr-96, to lugnet.robotics.handyboard)

How is the beta-test of the expansion interface progressing? Anybody care to estimate when the design might be finalized so I could purchase one? How much would a kit be expected to cost? \---...---\ \ John Mathews jkm@po.cwru.edu \ \---...---\ (29 years ago, 2-Apr-96, to lugnet.robotics.handyboard)

|
|
What should be the nominal voltage of the DC-Motors for the handyboard, I know that in miniboard its 6v - 36v. Thanx. Hachemi. (29 years ago, 3-Apr-96, to lugnet.robotics.handyboard)

Do you have to choose a transistor that will switch somewhere near and below 9 volts? Cause Fred mentioned that the handyboard is rated for 9V motors. But, does this mean that the pulse generator make 9V square waves? (...) (29 years ago, 4-Apr-96, to lugnet.robotics.handyboard)

I think the question on how to run higher current motors has got to be the most asked question here. Maybe we should add more info to the FAQ or something. Anyway, here is Chuck McManis' solution from a while back. I hate to send out something that (...) (29 years ago, 5-Apr-96, to lugnet.robotics.handyboard)

How many Polaroid range sensors can the expansion board have up to. One? What kind of signal does it produce? (29 years ago, 5-Apr-96, to lugnet.robotics.handyboard)

Is there a way to get sub-milisecond times measured with the handyboard? I was thinking of trying to modify msecond but I can't look at it now that it is a primitive. Dirk (29 years ago, 7-Apr-96, to lugnet.robotics.handyboard)
