[dorkbotsea-blabber] human-sensing disco floor, vintage 1999, FREE to a good home!

[Michael Clarke]

Sitting in my garage is a touch-sensitive disco floor, an old piece that
I've been schlepping around for several years (actually, since the
previous millenium) and have now been ordered to get rid of due to its
large size.  It's about 4' x 4' x 6" deep, a wooden grid frame underneath
sixteen 1' x 1' lexan tiles with different color theatre gels and tracing
paper diffusers attached to the bottom side, so that each tile lights up
uniformly in one of several different basic colors.  The light source is
an MR16 12V halogen bulb underneath each square; each tile also has an
Interlink FSR that acts as a detect switch (with no detent) when a person
steps on the tile.  All the lights and sensors are wired out to a single
ribbon cable that can be plugged into a control board.  The control board
has long-since been salvaged for other things, but it would not be hard to
create one -- just need a MCU, a lot of I/Os, some power FETs, and a hefty
12V supply, and it should be back in business.  A few parts have been
salvaged from the floor (mainly about 3 of the lexan tiles) but otherwise
it's in pretty good shape.

There's a photo of it here:

The sole catch is that you have to find your own means of picking it up 
and carting it away -- it won't fit in any kind of transportation that I 
have available.  Best days to get it are weekends, Wednesdays or Fridays.  
Drop me a line if you're seriously interested.
