Thanks John, I wasnt getting any mail? somehow things just started bouncing and I couldnt recieve e_mail here at this address? But its fixed now. Anyway I now...
Hello everyone I want to use more than one srf-04 sensor in one HB,but I don't know how to do. Can anyone tell me how to do it step by step? Thanks a lot!...
First of all, an announcement: The polaroid 6500 sonar has been purchased by Senscomp (www.senscomp.com). They redesign the card (same stuff, just more modern...
Can anyone tell me if the Handyboard can receive an AC voltage through one of the analog input pins or can it only receive DC voltage signals? Also, if it can...
hi, I have the handyboard and the expansion board, i have also two continuous servo motor. I built the robot using the two continuous servo motor.i can"t add...
the command "init_expbd_servos(int action)" only turns on or turns off the servo's, for example, to turn them on you would put init_expbd_servos(1); to turn...
Hi I've downloaded the Retina-project, from here: http://plan.cs.drexel.edu/projects/legorobots/retina/ . I'm trying to run it on my HB. The problem is that IC...
IC does not like casting char as int. change the char types o int and replace the peek(addi) with c1= a/256; c2 = a%256; This is probably worth a bug report...
Fellow robot enthusiasts: Mark your calendar our annual Botfest robotics exhibition and Botball robotics contest!! Botfest/Botball will be held on Saturday,...
Hi,there... i'm a ME student.i'm searching information about constructing an "egg" grabber (gripper)robot. For now, i'm trying to accumulate some theoretical...
Hi All, Doing something new (to me) w/ an "encoder" on the HB. I've got a simple Normally Open switch hooked to port 7. When i call digital (7), it returns 1...
The interrupt driven encoders (encoders 0 and 1) are capable of counting rising and falling edges on the input pin up to about 100KHz. What is being counted in...
You know your stuff Jim. It only took me a while to find out where port 2 was. I assume it's what is labeled as Bit2 digital in on the HB diagrams, because...
In trying to use the GP2D12 with the handyboard, every reference says to remove the pull-up resistors. I prefer not to violate the handyboard in this way and...
What are you having problems with on it? If you are having problems grabbing the egg, here is the best idea from the top of my head... (Hmmm... now I feel...
I haven't had any adverse side effects from removing the pull-ups. the only side effect is the sensor port "floats" rather than retuning a constant 255 when no...
Mark, Good, The digital 12 and 13 are used for encoders 2 and 3. An opti-switch (EE-SX1601 Beam Break sensor for instance) will generally eliminate the bounce...
... I get this more often than not with IC4 - I've reverted to using ic3.2 which works 90% of the time with code that ic4 chokes on, and also gives me...
just added a 16 servo controller to my handyboard, thought you guys would be interested :) I sacrificed two of my motor outputs, as I have more use for servos ...
Hello, I was trying to connect the cmu cam 2 to the handyboard. I tried using the same RJ11 cable i had used for the CMUCAM 1. And tried to connect it to TTL...
I have the source Pcode for ic4.xx, but do you have a way to re-compile it? You can't just use as11.exe. You'll need either Randy Sargent's unix comiler or...
I believe its there to separate the motor ground from the signal ground - without it, alot more electrical noise from the motors would get into the logic,...
I have only the base handyboard, and IC4 works 100% with the 'expansion' library - just don't call any of the expansion board specific functions (dig. out,...
I have kent & randy's dos compiler, but thanks for the tip to check this :) also, someone else has sent me pcode430.asm already but thanks for the offer....
could be the inductor between battery ground and motor ground doing something wierd - stick a snubber cap across their power connectors and see if that helps.....
Yah, it has become rather obvious now when I look at it. That if you are not using the motor driving circuit we don't really need this inductor. It just acts...
Can anybody give me a brief outline on how to use quadrature encoders with the handyboard (with expansion board if that makes a difference). I have been...
