 | | handyboard in Canada? (Montreal?)
|
|
I'd like to know, is anyone here from Montreal or the rest of Canada? Is there any distributor for handyboard parts or kits around here? All the ones I find are in the states (or hong kong...) -- You do not wish to know anything, you wish only to (...) (24 years ago, 21-May-00, to lugnet.robotics.handyboard)

Follow this link for data about the GP2D12. At the bottom, there is another link for Handy Board interfacing information. You have to cut a trace because the analog inputs on the Handy Board are connected to pullup resistors. The GP2D12 won't work (...) (24 years ago, 20-May-00, to lugnet.robotics.handyboard)

Greetings, I've looked, but don't seem to be able to find any relevant info. How does one hook up one of these beasts to the handyboard? I remember reading something somewhere that a track needs to be cut to do this - something I would like to avoid (...) (24 years ago, 20-May-00, to lugnet.robotics.handyboard)

(...) These two (...) ports. (...) I built the Expansion board in order to control servos. I cannot use the additional analog inputs because I have destroyed analog port 0 and 1. Is it possible to multiplex other analog ports? What software changes (...) (24 years ago, 19-May-00, to lugnet.robotics.handyboard)

Has anyone used the Hamamatsu C3704 Drive Circuit and the R2868 Flame Detector with the handyboard? The detector works great on my scope but I can't get the Handyboard to read it on a digital in port. Do you have to add a capacitor to lengthen the (...)

(...) That's what I was thinking too. But there is another consideration: the 6809 is a different class of processor than the 68HC11. The HC11 is a microcontroller while the 6809 is more of a general puropose microcomputer CPU. Although either could (...) (24 years ago, 18-May-00, to lugnet.robotics.handyboard)

Vic, Lots of programs handel Gerber files. They are the standard for print / storage of PCB board files. If you don't have such a program, then download one form the numerous freeware/shareware sites. Most electrical type programs would give this (...)

Vic, Depends on if you want to be done this year or not. If time and money are no object, designing and building your own board from scratch would be exciting and after just a few interations you could probably have one that is reliable. By the time (...)

A friend told me he has a development system for the motorola 6809 and he could give it to me. I guess this would be good, I would be able to make my custom boards. But, how does the 6809 compare to the 6811 or other microcontrollers (Basic Stamp, (...) (24 years ago, 18-May-00, to lugnet.robotics.handyboard)

Hi. I'd like to make my own handyboard if I can find all the parts in my city. But I have a problem with making the PCB... I have a friend who has a plotter and could draw it, but the layout files are GIFs and he uses Autocad (old computer, old (...) (24 years ago, 18-May-00, to lugnet.robotics.handyboard)
