You should be able to "piggy back" two motor driver chips. The normal ones for the HB are capable of about 1Amp or .6Amp. Use another 1Amp chip and you should be able to source 1.5Amps. Although, I imagine that using identical chips would be (...) (28 years ago, 28-Jan-97, to lugnet.robotics.handyboard)

Well I wanted to demo my new robot it was cool, but the day did not turn out to well. I think I switched the phone cables. When I tried to connect my interface board with the HB, it would not run IC.

1. Is it possible to expand the 32K RAM of the Handy Board? If so, how? 2. We will be using two shaft encoders (HEDS5500 from Hewlett-Packard) for our project. How can we interface the shaft encoders to the Handy Board? What inputs do we use? Does (...) (28 years ago, 28-Jan-97, to lugnet.robotics.handyboard)

I'm using the 1.2 volt NiCad's wired in series to give me 9.6 volts. If I want to get rid of one or two of the batteries, will the handyboard still run at 7.2 or 6.0 volts ? What is the minimum voltage that the handyboard will run on, 5V ? I dont (...) (28 years ago, 27-Jan-97, to lugnet.robotics.handyboard)
