[Randy Sargent] spake unto the ether: (...) Sigh. I can't forsee our Autonomous Robotics course buying 15 copies of IC 3.x or greater until it supports case/switch. It's the only feature that our students using freeware 2.81 really complain that (...) (26 years ago, 28-Aug-98, to lugnet.robotics.handyboard)

| | Resend: problems with main()
|
|
I posted earlier in the week about having a problem with the SRAM. I have determined that there is not a problem with the SRAM on the handyboard. The problem is that "main()" is not executing on reset like it is supposed to. The program that I am (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Hi, There is another way to get the Polaroid sonar unit. And that is to find an old Polaroid camera. That's the hardest part but allot of people bought them and are not using them any more. When you open it up there will be the Sonar board complete (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Phillip and others, To this excellent exposition I would change only one thing: (...) Change this to : "Write this pattern down neatly IN YOUR ROBOTICS NOTEBOOK." One of my professors at school noted that the most important thing he learned in (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Phillip First step is to put a piece of tape on the shaft so that you can clearly see the shaft turn. Next determine what kind of motor you have (you have probably already done this). Get an ohm meter and determine which wires are connected to (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Hi Philip, are you shure, you have the right pins from the stepper to the outgoing pins from your chip. Have your stepper 4,5 or 6 cables? If you exchange the cables, your stepper motor only do some vibrations or doing nothing. The easiest way to (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)

Jeroen van der Vegt, Let me suggest some articles. First "Sonars on the Cheap" by Keith Payea page 20 of the Fall 1995 issue of The Robotics Practitioner. This looks lie about a $30 design. Second "An Experimenter's Cheap Robotic Sonar System" by (...) (26 years ago, 26-Aug-98, to lugnet.robotics.handyboard)
