can you make each square IR transparent? then include an ir port under each
one with an ir transceiver in each piece, add a 1wire address part and away
you go. you can then identify each part and where it is on the board. you
will need to connect your board side ir transceivers in a matrix fashion to
getyour location reference, other than this method rfid would work very well
too provided you could contain your read field.

Subject: [OT:] Chessboard (sensor)


Hi!

I am looking for a (wireless) sensor to be located on each of the chess
pieces in order for a program to know which piece is on any square of a
chessboard.

I do not want a mechanical sensor. I thought on a sort of radio emitter
but it has the problem of the small surface of the squares on a
chessboard. Also there should be a lot of different signals, at least
one for each type of piece of each color.

The chessboards that do know about the pieces on top of them need a
starting position to be typed in some manner, then the program just
remember the movements and knows any time where the pieces are. I would
like not to type that starting position and also the program to be able
to detects if the player is cheating.

Any better idea?, any already made chessboard with this features?

Thanks,
Diego.
