So, I saw the Scientific American show on PBS and I was completelly geeked! It was too short. I was most impressed by the tennis ball capturing contest and by Newton Lab's Vision Car entry. Cognachrome is very cool. After seeing the show I logged on (...) (27 years ago, 11-Apr-97, to lugnet.robotics.handyboard)

(...) I believe the wattage just tells you how much power the resistor can reasonable dissipate. Therefore using a transistor which can dissipate more power than what the design calls for is alright, but using one that dissipates less power is bad. (...)

I have a question on the replacement of the a specific resistor. On the handyboard there is a 3.83K 1/8W resistor. I just received in the mail the last pieces for the board and was shipped a 3.83K 1/4W resistor. Is the wattage citical on this (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

Hi, This question doesn't really belong to this mailing list, but since some of you know quite a lot about microcontrollers I thought maybe someone could help me. I'm working on a project about A Management System for an Optical network. Therefore (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

(...) Here is a simple example of how to do 'different things' when you press various buttons on your remote. If you press digits, they are displayed on the LCD. If you press rewind, the LCD is cleared. When you press stop, the program ends. If you (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

Hi, Can someone help me understand encoders.asm? This is what I deduced from the code and I'm wondering if my guess is correct. 1. When TIC3 and TIC2 inputs are changed, an "interrupt" in execution occurs and and execution immediately jumps to the (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

could the voltage divider circuit shown in the Mobil Robots book (page 116 fig5.20b) be implemented as is OR does the built in pulldown resistors cause it to be modified. Thanks for all the brain dumps, victor (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

How would I use an if/then statement if I used the onboard IR reciever? Earlier, I downloaded a program that Max Davies wrote to determine the different variables for my remote. In the readme file, it says that the rules are set by a command like (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

Victor, The peek(0x1000) statement returns the byte at memory location 1000 (hex). In C, the '&' operator is a bitwise AND. So, what you are doing is ANDing 4 and the contents of 0x1000. What's really going on is you are interested in only bit 3 (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

Hello! Just 1 thing today: 1. Is there any sort of chip that can be wired up to the HB's motor ports, and then convert it to 16 (or less, maybe) outputs? phil thehahns@nconnect.net PS: does anyone know of any robot designs that will allow a robot to (...)
