The LEGO sensors and the RCX are the same thing. The standard Handy Board (without an expansion board) can handle all of the passive LEGO sensors such as the touch and rotation sensors. The expansion board is needed to use the active sensors such as (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

| | Re: Higher voltage for HB battery
|
|
I find that the ideal solution to this situation is to build a power system for the robot. Maxim, Linear Technology, and National each make very easy to use switching regulators that can provide highly efficient DC to DC conversion. Building a (...)

Some of the expansion board kits (all? sorry, haven't been paying much attention to the extension boards yet) mention that they have slots for LEGO style sensors. Does this mean the sensors they use on their RCX/Mindstorms stuff? What's the (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

| | Higher voltage for HB battery
|
|
I would like to know whether the HB can be used with a 12 V (ten AA cell) NiCd battery instead of the standard 9.6 V (eight AA cell) NiCd battery. Specifically, (1) Would the HB be damaged by the higher voltage, (2) Would the HB function properly (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

Bob, What other code are you running? What does your motor code look like? Does anything get hot when this happens, like the motor control chip, the hex inverter or the voltage regulator? Gary Livick (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

| | Problem with my board
|

I am using a HD with expansion board. Periodically when I run the motors at anything less than 100 they spin with very little power and both the red and green lights on the board light up. At full power the motors work perfectly with only the green (...) (25 years ago, 9-Jan-00, to lugnet.robotics.handyboard)

Hello All, Has anyone developed an IR receiver/decoder to allow a HandyBoard robot to be controlled by a LEGO IR Remote (#9738)? My LEGO 'bots are great when they're controlled with the LEGO IR remote ... grade school kids really like the remote (...) (25 years ago, 8-Jan-00, to lugnet.robotics.handyboard)

Hi, This question is not HB specific, sorry about that. I have bought a CCD camera board, and I want to add it to my robot together with a TV transmitter, the problem is that the camera has not built in audio, so I will like to know if someone has a (...)

Hi Sonny, I've played with Voice Direct and also with the HM2007 chip. Both of them work fine in a quiet environment, but in my limited playing they were both overwhelmed by the ambient noise of a moving robot. They both are speaker dependent, and (...)
