Not sure who you are? tomb? Anyways, I noticed mention of a compass.... I once looked into the idea of using a flux gate compass to obtain heading info. After finding that the inexpensive (affordable) models would only obtain info at a resolution of (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

Richard, Thank you for your response. I must admit that my electronics knowledge is limited to basic theory and some practice. I depend on others, such as yourself, who have had more experience. Furthermore, I would greatly appreciate any thoughts (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

Matt, You mentioned an IR device from Digi-key. Can you expand (part no.) tel phone no. for Digi. Process analog info from IRs to digital data for HB? What IRs are compatible and where might I get this stuff. Your info into this would be greatly (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

Well it works. A couple people have asked for it. Turns out the stupid V2X docs are wrong again! Like the product, but bad docs will kill it! Even if you don't have a V2X, I have seen enough traffic asking about using the SPI for things on the HB, (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

Don't those tend to have swapped conductors too? I thought that the receiver cords were slightly different from the other cords. You might have to crimp new connectors on the end. -Jeremy (...) ___...___ Jeremy Green jag@world.std.com (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

Speaking of noisy lines, I was thinking of getting one of those telephone cords that's coiled helix-like to colapse the wire. Now that we're discussing this topic, I am wondering if this cord would effect the electronics. The thought came up to me (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

(...) One could consider plastic optical fibre for that length. The diameter is small. It is flexible. No shielding required. You could have one for each direction of signal. Motorola had a plastic optical fibre kit years ago. Have fun. ---...--- Ed (...) (28 years ago, 4-Mar-97, to lugnet.robotics.handyboard)

(...) No, that is wrong; the RS232 is converted to TTL at the serial interface board, so you do have TTL on the phone cord. In any event, I would guess that 50 ft. would not be a problem; we're talking about 9600 baud here which is pretty slow. BTW, (...) (28 years ago, 4-Mar-97, to lugnet.robotics.handyboard)

(...) No, the MAX232 chip on the charger board converts from 12V RS232 coming out of the serial port to TTL level RS232. What goes down the line to the Handyboard is 5V RS232, which goes straight into the HC11 and at only 5V levels is more (...) (28 years ago, 4-Mar-97, to lugnet.robotics.handyboard)
