(...) I had a similar problem, and while I couldn't exactly fix it, I managed to avoid it as follows: I had a serial mouse on COM1 and the HB plugged into COM2. I could *not* download like this no matter what I tried. So, on a whim, I found a 9 to (...) (26 years ago, 30-Mar-98, to lugnet.robotics.handyboard)

Can you hook up RC servo signal inputs to the motor drivers? It looks to be feasable as both require a pulse width modulated signal but I'm not sure if the motor driver's carrier frequency and range of pulse widths is suitable. Any ideas - it would (...)

hello, I'm having trouble downloading on my Dell 300mhz PII computer but for some reason have no trouble downloading on my old 486dx2 though.

Does Gleason Research still sell the non-assembled HB kits. Because I went to their web page but they only had the assembled version. Thank You, Peter Eacmen (26 years ago, 30-Mar-98, to lugnet.robotics.handyboard)

(...) Try Wirz Electronics for the sonar module. Last I heard, they will sell you a single unit for about $50, and I'm pretty sure you can order via the web. Unfortunately, I don't think that they sell the V2X. You can also get the sonar module (...) (26 years ago, 29-Mar-98, to lugnet.robotics.handyboard)

Chris, I got the same problems with the IR detection. I read somewhere that this is a problem when you use IC and multi processes. The solution could be a "hog_processor()" statement in the IR routine. My question to you is. How will you solve the (...) (26 years ago, 29-Mar-98, to lugnet.robotics.handyboard)

| | using 7.2v battery with HB
|
|
this actually should be fine. the characteristic of nicads is to have a fairly level output voltage as they discharge, and then drop off sharply when the power's all gone. so it should be no problem. fred (26 years ago, 29-Mar-98, to lugnet.robotics.handyboard)

Wait! Sorry, I was confused! I thought the HB originally battery was 7.2V. Silly me. :-/ Why didn't anyone correct me??? Well, you kinda caused the confusion though. You mean 7.2V vs. 9.6V? or 8.4V vs. 9.6V? ...cuz 9.6V is the original eight 1.2V (...) (26 years ago, 28-Mar-98, to lugnet.robotics.handyboard)

(...) The correct actual addresses are indeed all in the $10xx range. When you index off either the X or Y register, the offset value is only 8 bits, or 0 to $FF. This is why you're getting the warning messages, the high order $1000 is being (...) (26 years ago, 28-Mar-98, to lugnet.robotics.handyboard)
