Philippe ... I strongly recommend that you look into the HandyBoard
before you commit to the MiniBoard.
http://el.www.media.mit.edu/projects/handy-board/
It has drivers for 4 DC motors, 9 digital inputs, 7 analog inputs,
two onboard switch inputs, one potentiometer input, IR input/output,
a piezo beeper, and a 2x16 LCD. The expansion board adds 10 additional
analog sensor inputs, 4 inputs for active LEGO sensors, 9 digital
outputs, 6 servo motor control outputs, a connector for a Polaroid
6500 sonar ranging system. The HandyBoard can be programmed with
Interactive C and/or 68HC11 assembler ... and there is a large on
line support group ... including input by the father of the Handy
Board, Dr. Fred Martin.

The HandyBoard is available assembled from:

and assembled or kit form from:

Patrick Hui is based in Hong Kong and sells world wide.

The LEGO IR tower is used only to program the RCX ... once programmed
it can be powered down, taken to another location, and powered back
up to run the loaded program(s).

The FingerBoard by EAS is a great lower cost replacement for the
HandyBoard ... it's compatible in that it also runs Interactive C.

If you can afford two "brains", then one RCX and one HandyBoard make
a great pair. I have three 'bots ... can lift the RCX out and drop
in the HB, and add a bunch of sensors and behaviors.
Have fun,

| Hi legoguys ! Being very interested by all those robtics stuffs, i'm looking for a good devellopement system. I intend to build or buy the miniboard, instead of using the lego RCX. Mainly to get more inputs/outputs and flexibility. I have some (...) (25 years ago, 13-Jul-99, to lugnet.robotics)
