How about lifting pint 8 of the L293 chip and running a wire from it to a 7805 regulator (not the one used for logic). You could also run the wire to a separate battery pack. 4 NiCds in series gets you real close to 5V with no regulator. In motor (...) (28 years ago, 22-Dec-98, to lugnet.robotics.handyboard)

Hi, I stopped working with the handyboard for a while but just started back up again. I put the expansion board onto my handyboard and began testing it. After testing the general tests done before with just the handyboard I started testing the servo (...) (28 years ago, 21-Dec-98, to lugnet.robotics.handyboard)
