 | | Here's Spazbot based on the handyboard
|
|
I put up a website regarding the robot I built with the handyboard. I'll be designing more sensors for it soon, Spazbot is at nfn.no-ip.com/spazbot (24 years ago, 19-Sep-00, to lugnet.robotics.handyboard)

| | Hall Effect
|

You are going to find that it is not the encoders as I thought also. The HB seems to be incapable of reading correctly. I don't know why, but I have been trying for about 3 months with no/or little success. Someone knows, but no one is telling. I (...) (24 years ago, 18-Sep-00, to lugnet.robotics.handyboard)

| | Sonar and Compass together on expansion board.
|
|
I am working in adapting a PNI compass to the handyboard. And I have a 6500 sonar board connected to the expansion board, here's my idea: Use a Lithium 3.6V battery to save calibration settings after poweroff M/S is jumper selectable Calibrate is (...)

| | Pcode benchmark
|
|
The pcode includes a benchmark primitive to see how well the multitasking environment is functioning. Does anyone know how to access this function?

| | Communication Protocol
|
|
Hi everyone, I'm working on a project that implies the communication of the Handy-Board with a PC computer via the serial port. The person who is in charge of programming the software that will run on the PC asked me what is the communication (...) (24 years ago, 15-Sep-00, to lugnet.robotics.handyboard)

| | IR transmission
|
|
What value resistor should I put in series with the IR led for transmitting from the hb ?. The red led that is present as an indicator is rated for about 5mA (I think they normally run at about 2-3mA) using a 1K resistor (R5) so should I run the IR (...)

| | Got some code for you: Sonar on handy in feet & inches!
|
|
Hi, I wanted to see how to convert the sonar hits into feet in inches. Well as the textbook rule goes it looke like it takes 333.333 ticks = 1 inch round trip. Since the timer is running 2,000,000 counts per second. But in real life I had to fudge (...) (24 years ago, 14-Sep-00, to lugnet.robotics.handyboard)

| | Hall Effect Encoder = sloppy, going optical
|
|
Well the Quad hall effect switch encoder does not give repeable resolution. If I say 14 ticks = right turn (motors going in opposite direction) well. sometime it is on the money, sometime it's not. And I don't have a racer.. I have it running slow (...) (24 years ago, 13-Sep-00, to lugnet.robotics.handyboard)

Sure.. hey I thought I replied to the list. Here's the picture so far.. note: lugenet doesn't allow jpeg attachments so You will get the image, lugenet will reject them. I am hoping to put up a webpage soon. I've got a few sensors I am designing (...) (24 years ago, 13-Sep-00, to lugnet.robotics.handyboard)

|
|
Hi, I am trying to use the 100 step motor code and a Hb expansion board. I can get either one of them to work ALONE ONLY. So I can only use the expansion board. OR the 100 step pcode, How do I install both so they dont conflict with one another. (...) (24 years ago, 13-Sep-00, to lugnet.robotics.handyboard)
