Well, I went with separate h-bridge to maintain PWM and it turns out that even though the motors are geared down, they still don't have enough torque to haul around all the batteries. Looks like I'll stick with 9v motors... Thanks for the (...) (26 years ago, 20-Oct-99, to lugnet.robotics.handyboard)

Hey why use the palm pilot? You could use the color gameboy :) I mean it has a IR port on the top. The only problem is the fact that it uses cartridges :( If anyone can make a cartridge, then there is (or at least used to be) a section on (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

It looks like they have changed the boards fairly significantly. Many parts substitutions -- notable the capacitor farm looks like it has been replaced by a battery backup capacitor. The overall parts count seems to be reduced in more places than (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

THis may be a dumb question on my part, but we are getting stack overflows on for loops such as for(int i = 0;i<1000;i++){...} when using values over 100 or so. Is this an 8bit counter thing or something else? Thanks, Owen Popplestone (26 years ago, 20-Oct-99, to lugnet.robotics.handyboard)
