O.K. I haven't been flamed by anyone for my last question, so I'll try asking the question a different way. If there's no-one out there with >past experience<...
Hello, Here is a example of using RF transmitter/receiver on Handyboard http://www.leang.com/robotics/info/articles/serialcom/serialcom.html You can browse our...
Hi!! I am a computer science graduate and new to electronics. I am a naive in this field. However I have to connect a CMU camera to a MIT handyboard. I am...
... Well, if no one can spare their handyboard for a while then I need to know how big it is. What are the dimensions of the handy cricket and its expansion...
I apologize in advance if this is a FAQ question (though I don't think so). Today I (correctly) plugged in a Cirrus CS-248 servo (supposedly workable with the...
Perhaps you could use 1 max3110 connected to the SPI (with the right baudrate for your mouse )or use the already wired rs232 9600 bauds, with witch you...
I made the terrible mistake of plugging in the DC adaptor to the Handy Board, rather than to the serial interface. Now, I have a strange problem with the...
HI, I faced some problems while I was using the Lego Light sensors on the Handy Board. I'm fitting 2 lego rotation sensors and a light sensor on the Board. ...

Make sure the ports you are trying to use don't have PULL UP resisors in line. Another thing...if you are turning the rotation sensor fast, you might need to...
I replaced R14 with an equivalent resistor from the expansion board, which we aren't using. Unfortunately, the HB still displays the same problem as described...
Well its been setting for a while(about 2 months) Charged the battery last nite, and today when trying to download pcode.. I had a problem... When pressing the...
... I have checked the battery it seems to be holding a charge.... And I also checked the voltage regulator it seems fine as well. Could something else have...
Hi, I am having a problem with connecting Lego light sensors(blue block with a green and red diode on it) to the expansion port of the Handyboard. When using...
I am considering buying the handyboard for a robot i am building, however the motors that i am going to be using pull a amperage of about 6amps. I am thinking...
Hello, I'm building a HandyBoard and I'm at the stage of loading the pcode to test the memory circuit. The pcode loads fine, but when I reset the board it...
Its really acting wored.... when I turn it on.. both the batt led and the green light(pwr) stay on, and wont go off. The led for the (ir) also stays on, and it...
Problem solved! After carefully cleaning the bottom of the circuit board with a static free brush, my HB comes up to the Interactive C screen quickly. I'm...
Hi all: I have a problem with one and two dimention arrays. Unfortunately, the handy board that I have does not accept: 1.-one dimension array that is greater...
Hmm. I remember reading somewhere a limit on array size, especially on 2 dimensional arrays, but I just browsed through the HB manual, and didn't see anything....
Hi Sam: Thank you for your e-mail. I already check the HB manual a week ago to see if there is any array limitation; according to the manual that I have,...
Not all version of IC support 2D arrays. But this is trivial to code around; if you need two indices i and j, with bounds of 0 to 15 on each, then you can use...
Hi Fred: I just want to say thank you; your comment had solve my problems. By using the code "persistent" to declare 1D or 2D arrays as a global, my...
I checked L1 and C9 and they are both O.K. Any other tips? I'm a software guy and I'm a bit lost here. What other components are likely to have gone bad?...
