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)

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 (...)

| | 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)
