  Motors start when reset
 
Every time I reset the board, the motor port LEDs light up, if a motor is connected to the motor ports, the motors turn on. This happens until the reset is complete and I hear the beep sound. Is there a way to prevent this? Regards, ...Ameen Suleman (26 years ago, 16-Feb-99, to lugnet.robotics.handyboard)
 
  Re: shaft encoders for a track drive
 
(...) Depending on how your tracks are constructed, if they have holes or slots that light can pass through you can use the tread directly in place of the encoder wheels.

  GREEN MASKING
 
Dear Mr Fred Martin, Green masking files are available in Gerber format (pardon me if the spelling is wrong). We do not know how to open these files. Can you send us detailed instructions on how to open these files. Yours sincerely, Nitin (26 years ago, 16-Feb-99, to lugnet.robotics.handyboard)
 
  Re: Stepper Motor
 
Keith, I've succesfully connected two steppermotors from old diskdrives to the HB, one 1.8 degrees and one even 0.9 degrees/step. I found all the info I needed on the internet, and especially www.cctc.demon.co.uk...tepper.htm contains some useful (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)
 
  re: stepper motors
 
I have worked with two kinds of stepper motors with the handy board. One pair was purchased from LMDC. These are Astrosyn miniangles stepper motors. These were big heavy duty stepper motors. The other pair was from old 5 1/4 inch floppy drives from (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)

  Re: shaft encoders for a track drive
 
OK, now I too have my handy board, it's italian, not just the same, but has a 68hc11, and all those other thinks that make it just quite the original one similar to this. It will be interesting to see if we will can have, a day or another, a new (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)

Hi. We built encoders for a skid steered wheeled robot. There is a picture of it at: (URL) used an IR Led and reciever pair, and a white disk with 24 radial black lines, and had pretty good luck with the encoder, but bad luck with the info gathered. (...)

  shaft encoders for a track drive
 
Has anybody out there constructed shaft encoders for a track driven MOBOT. If any body has I would appreciate any help you could give me. I wasn't going to use shaft encoders but I guess they are needed for many things correct? Is there anyway to (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)

  Expansion board test routine
 
Hello all, Well here it is, for what it's worth. The functions are pretty obvious, it works just like the original hbtest.c that Fred wrote. To try servos other than #5, you'll have to edit the line: servo5=(16*knob()); In the test_servo() routine. (...) (26 years ago, 15-Feb-99, to lugnet.robotics.handyboard)
