(...) Yeah, the HB and sensors that Patrick Hui sent to me worked great, too. Not only that, but he promptly answered my questions via e-mail. I haven't dealt with Gleason yet, but I wouldn't hesitate to recommend Mr. Hui. -- Will , , __@_/ \_@__ |/ (...) (25 years ago, 6-May-99, to lugnet.robotics.handyboard)

Ryan, Well, it worked for me... Which version of IC are you using? I'm using the Newton Labs IC version 3.1 but as far as I know the program should work with all of the versions. If you tell me what you're using I'll fire that version up and try it (...) (25 years ago, 5-May-99, to lugnet.robotics.handyboard)

Have you openned the files in a simple editor (I use BBEdit)? If not, try openning them and check what is at the end of the program lines. Sometimes, pending on how it downloaded, it will have "squares" at the end of the lines representing (...) (25 years ago, 5-May-99, to lugnet.robotics.handyboard)

Peter, I've recently bought a Handy Board kit from Patrick Hui in Hong Kong. Contrary to your experience, I was very pleased about the quality of the parts Patrick sent me! Also, his price was very competitive to Gleason's (which was the reason why (...) (25 years ago, 5-May-99, to lugnet.robotics.handyboard)

Greetings all! I just got the Sharp GP2D02 ir distance sensor and I got it all hooked up the way that Barry Brouillette's tutorial explained, and I downloaded the new expansion board drivers, but when I went to load the Barry's IR drivers, it gave (...)

(...) This is actually a very good question. Generally, math function libraries use what is called a Taylor series expansion of a trigonometric function to return an approximation to the function with arbitrary precision.

(...) Dear Andrew, You want the angle that line joining G and P make with X axis. That is arctan of the slope of the line from P to G. slope =(yP-yG)/(xP-xG) hence, theta = arctan ((yP-yG)/(xP-xG)) where P=(xP,yP) and G=(xG,yG) Note that this angle (...)
