Hacked Wiimote Used As Water Level Sensor. We've all been
entertained by Wiimote hackery in the past, but I for one can
never tire of the new inventions constantly being cooked up by
clever sausages like this guy. Using the Wiimote and an LED
light, William Luxemburg from the Delft University of Technology
in the Netherlands knocked together a water-level sensor,
measuring evaporation. As you can see from the picture, a tub of
water with a Wiimote pointing at a plastic boat is a simple and
cost-effective way to achieve the same—or even better—results
that pressure sensors costing $500 or more can produce. Of
course, it wasn't merely a Wiimote trained at a boat in a tub of
water, which solved Luxemburg's dilemma. He re-programmed the
Wiimote's output, and as it can sense movement better than a lot
of other devices out there (closer than 1mm accuracy, as Wired
points out), when it was connected wirelessly to a laptop he was
able to receive real-time information on what the water level
was doing in the tub. Luxe
