Hi. I'm still having problems with my servos and the board. I got the servos connected to the port 9 and the fourth port from the right on the handyboards expansion bus.

(...) Someone could probably give some very good reasons why 45 degrees is a good choice. For me it was common sense and experiment. Less than 45 degrees from ahead and the angle the IR is hitting the wall is too "shallow" and I don't get a return. (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)

I am designing a circuit that requires a 567 tone decoder to detect a 500hz signal and I need some help. I don't have any technical manuals available with that chip in it and I need to know how to wire it up. If someone could post a design or send (...)

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)
