Hello all, I've been playing with IR proximity sensors, and wonder if anyone can provide some suggestions. I hooked up an IR LED (Radio Shack 'high output IR LED') to the Handyboard's IR output with a 330ohm resistor in series (the smallest value (...)

Hi Joseph, No, I have never had any problems with Digital Micro Systems. Actually, I am pleased with them. I ordered an assembled board a few months back and got the board on time. Later on I was suspecting something wrong with the board and I had (...) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

Howdy all, They say imitation is the sincerest form of flattery- Thank you Fred Martin for designing such a cool board like the Handyboard! I got one last summer hopefully to be one of the CPU's in my robot- but alas it didn't have enough I/O ports (...) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

I really don't know what the problem with your compiler is. Maybe it's the wrong one for your programming language or for the board you're using. In the version of IC I program with, the program would look more like the following. Maybe that can (...) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

Is there anywhere I can purchase IC 3.1 via check? I'm not the (un)lucky owner of a credit card, and paying by check would make things a lot easier for me... ---...--- Jeff Keyzer UCSD EE Major jkeyzer@ucsd.edu (URL) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

I am still getting a strange compiler error and I can't figure it out. The exact error is: Compiler error! 62 extra bytes left on board stack Sometimes the number of bytes is more and sometimes less. I'm sending along a copy of the code that is (...) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

Sounds to me like your LED is just not focused straight ahead. I found that sticking the IR LED in a Radio Shack panel mount LED holder (cat no 276-080a) worked the best for focusing the beam of IR. I had tried soda straws and other things, but the (...) (27 years ago, 21-May-97, to lugnet.robotics.handyboard)

Kent, I read your quick explaination of how to connect the Polaroid 6500 sonar board to the HandyBoard, and I have a couple of questions.... Mainly, you mention that the INIT signal plugs into pin 9 of the second motor driver chip socket, and that (...) (27 years ago, 20-May-97, to lugnet.robotics.handyboard)
