Hi all, first, the URL: (URL) went to last weekend's Fire-Fighting Robot Contest at Trinity College, along with my colleague Steve Ocko, who had built a cute robot based on our network-cricket technology (see (URL) for more on that). We spent about (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

| | A few questions....
|
|
First I want everyone to know two things. First I am new to this list. Second, I have moderate knowledge of electronics.... Until about a few weeks ago, I had been working with Basic Stamps 1 and 2. After looking at all the information about (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

|
|
Well, actually, it's not power either. Power is V * I. Sorry, it's actually the voltage. ---...--- ericson mar Master of Engineering Candidate Project: Mobile Robotics mar@cooper.edu (212)353-4356 Department of Mechanical Engineering The Cooper (...)

The 100, 50, 40, etc. are not really "speeds". They are power. It is related to the average voltage level of your output. Speed depends on the torque and characteristics of your motor. You can hold on the the wheel and still drive the motor at 100. (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

When it first worked for me, I used the HB NiCd. I grounded binh and it worked. I used binh to measure like 7 inches and it worked fine too. ---...--- ericson mar Master of Engineering Candidate Project: Mobile Robotics mar@cooper.edu (212)353-4356 (...)

| | Re: Serial Communication: HB -> Win95
|
|
To answer my own question, at least partially, here is a Win95 Host program to communicate (single bytes) with the HandyBoard over a serial line: /* Win95 Visual C++ Host Code to talk to HandyBoard */ #include <conio.h> // _outp, _inp #include (...)

| | Re: IC stack problem
|
|
(...) The funny thing is, it doesn't complain about arrays smaller than 4x4. All values are stored correctly for an array of size 3x3. What's this 'magic' number 4 then? Jan Sipke van der veen (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

| | Re: loading files with IC
|
|
In fact, that's weird.. I can't answer to that. To me, I'm pretty sure that IC would have gave me an error, like when I try to load a C program without having loaded the ICB containing the special function used by this C program. For example, i (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

| | Re: Handy board help
|

You can build a stepper motor controller on a separate circuit board, then remove the motor control IC's off the handy board and use the output signals to control your stepper. Will have to write a program to run it. you will need a min of 4 outputs (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)
