Hi.. i have some questions about the exp. board and R/C servo, hope anyone can help me.. thanks.. From the "Expansion board software" homepage, it said that servo0=(value) is used to control the servo, may i ask how can i convert this value to (...)

Hi all, A funny thing happened. i tried to download a file. IC gave the message it was downloading, but just when it finishes it gives me an error saying "lost synch with board". then i unloaded some files and redownloaded the file again. this time (...)

Joe, As it turned out, the edge of the pulley was right next to and perpendicular to a long beam piece. We just used hot glue to glue it to the beam and held it in place until the glue dried and had no trouble at all. The pulley can't come out of (...)

(...) These are what I also have been trying to use to break the beam, they seem to be the best choice. My question was more about how you mounted the sensor. I'm curious to know what piece people had glued the sensor to, and to see if they used (...) (25 years ago, 29-Feb-00, to lugnet.robotics.handyboard)

(...) If you can burn PIC processors yourself, try my page at (URL) and bonk on the serial servo controller project. I have PIC12C508 code there that allows you to control 4 servos with a single 2400 baud connection. The code is set to allow a (...) (25 years ago, 28-Feb-00, to lugnet.robotics.handyboard)

Yes, there is a way. Check out the serial servo controllers at (URL) one of these that you use controls up to 8 servos, and you can chain a bunch of them together and go servo nuts. -- Will Bain P.S. -- I haven't yet tried these myself. I'm curious (...) (25 years ago, 27-Feb-00, to lugnet.robotics.handyboard)

| | Re: Problem on loadind Expansion board files

The problem is simply that the new expansion board code supercedes a couple of functions in the old lib_hb.c (and possibly in lib_hb.icb, too; I can't remember). If you go to the HB web site, you'll find a new version of lib_hb that's compatible (...) (25 years ago, 27-Feb-00, to lugnet.robotics.handyboard)

Whatever portion of the 40 mA that the HB requires for it's operation will "float over" the battery pack and be consumed by the board. The rest goes into the battery to recharge it. I haven't measured the current draw of my robot, but of course your (...) (25 years ago, 27-Feb-00, to lugnet.robotics.handyboard)

I understand that a handyboard in combination with the expansion provides a total of 6 servo motor controllers. However, I need 12 controllers. Is there any other ways to achieve this other than buying another set of handyboard + expansion board? (...) (25 years ago, 27-Feb-00, to lugnet.robotics.handyboard)
