(...) Sounds about right. Some displays are worse than others. I just happened to get one with a contrast that wouldn't work well until I did the above mod.

Some time ago I tried the use of the HB to control a RC Servo using the single servo control software that was available in the HB web page.

(...) All I know is I lost all functionality, i.e. program no longer ran. I poked for the problem, found I had 5V, and then found Ray Butt's Tcomp. I just opted for the easiest solution.

So you only recovered the power supply? Everthing else was bolwn up? I tested my motor chips and they appears fine so far as I can tell.

The wires that hook up to each sensor port were fed through holes in the body of the robot. We thought of making (...) (27 years ago, 3-May-97, to lugnet.robotics.handyboard)
