for RF communications, I recommend Linx Technologies (URL) They sell seperate transmitters, receivers, and antennas. For two-way communication, you would need two pairs, so the price is around $30 for a bidirectional link. They have speed ranges (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

After reading some of the discussions about wireless communications, I remembered an article from Nuts and Volts ( (URL) ) May 1998. The title of the article is "Naked Data", Explore the power of wireless data communications using inexpensive (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

The original IC and pcode was originally written on a Unix machine. There are scripts and a makefile that simplify the compile procedure. I use a Linux PC to modify the pcode all the time. If you have access to one, download the original pcode (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

There is an article in DDJ on the WOOKIE 68HC11 emulator in Mar 99... There are files in www.msoe.edu/eecs/ce.../resources including GNUs gcc C compiler with a back end for 68HC11.. I think that it is targeted for the rug warrior. You may need to (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

Hello I made some changes to the pcode_hb.asm file (by Julian Skidmore for the 100 steps PWM) and I need to compile/assemble it into a .s19 file (pcode_hb.s19) before I can download it onto the HandyBoard. It seems to me that I require both a C (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

I also found that my neon light in my magnifying lens lamp caused erroneous readings. When I turned it off or moved it away the readings normalized (gave the correct results). Shielding wasn't effective in this instance. I did completely away with (...) (26 years ago, 2-Mar-99, to lugnet.robotics.handyboard)

(...) I assume that your sonar pings (makes a clicking sound). If so, then you may be getting a premature echo. You might try mounting the transducer in putty to absorb vibration. You could try lengthening the blanking interval to make sure that the (...) (26 years ago, 1-Mar-99, to lugnet.robotics.handyboard)

| | Re: Bipolar Stepper Motors

First thing take an ohm meter and "read" your coils. From any wire you should have one other wire at a low resistance and two at a high resistance. This will first determine if you have it wired right. On my steppers the outside two form one coil (...) (26 years ago, 1-Mar-99, to lugnet.robotics.handyboard)
