Hi, I have bought recently a bunch of Sharp IR-distance sensors model GPD202. I'm going to use them for our laboratory courses, but I can't find the 4-pin connector this sensor uses. I would be please in anybody could tell me the reference of this (...) (23 years ago, 31-Jan-01, to lugnet.robotics.handyboard)

Hi all, I am trying to use the Sharp GP2D02 sensor with the handy board. I dont have the expansion, thus no real digital outputs. I do know that digital output 9 can be reconfigured to act as a digital output. I have tried modifying some of the (...) (23 years ago, 30-Jan-01, to lugnet.robotics.handyboard)

John, Like you, I recently purchased a Handy Board from Acroname. After doing quite a bit of research on the Internet to determine what my first experimental robotics platform should be, I felt confident that the Handy Board was the best choice. If (...)

Hi all. I've just completed construction of my handyboard and I'm very excited to start experimenting with it.

| | Re: Handyboard Battery
|

Brian, First I would check the voltage of the battery itself. You should get about 10 volts. If not you either have a bad battery or a problem with your charger. If the battery checks out, next I would check the poly-switch fuse. As a matter of (...) (23 years ago, 25-Jan-01, to lugnet.robotics.handyboard)

Yes, I'm answering myself. I now notice that Port C is being used by the LCD. Therefore, I'm guessing that this is part of the problem (the whole problem, a really big problem?). I'm still curious as to how Port C might be shared - is it still (...) (23 years ago, 20-Jan-01, to lugnet.robotics.handyboard)

I'm having a little trouble working with Port C on my 68hc11. A little background: the 68hc11 is part of a rug warrior pro. This board brings Port C out to an expansion socket which I can access.

It is possible that the pins of the 68HC11 chip are not making good contact in the socket. To fix the problem remove the chip, take a sewing push pin and make a hook in the tip. Use it to very gently pull out each pin connection in the CPU socket. (...) (23 years ago, 16-Jan-01, to lugnet.robotics.handyboard)

It's just an ordinary motor after you modify it to take out the feedback device, and you have no idea of where it is pointing at any time. Maybe you could have the robot turn in a circle to find the beacon? Or use a small stepper motor? You can (...) (23 years ago, 15-Jan-01, to lugnet.robotics.handyboard)
