Yes, many thousands... :)

My project will be an AVR detecting and predicting weather by analyzing the
acidity of an orange based on a PHE-9151 pH triple Teflon junction reference
cell.  It is known that the orange peel citric acid changes its pH level
based on pressure, humidity and temperature. Here in Florida old folks used
to predict weather by squeezing orange peel.  As a free ride, the AVR will
run powered by the same orange juice, copper and iron pins, organic battery,
even using a rotating 7 blue leds display to indicate weather in 14
different languages, along with time of the day, barometric pressure and
temperature. The MP3 player and 120GB hard-drive attachment was
desconsidered by excessive power consume, everyone understand that the
orange juice will not be able to generate the necessary power to drive the
80W power amplifier.  Everything the user needs to do is peel an orange and
squeeze it over the sensor.  In less than 5 seconds the rotating leds will
indicate the weather prediction for the next 6 hours.  The
on-board-programming will allow future software upgrades for 12 and 24 hours
prediction. The Xenon flashing lamp will be part of the project, flashing
when a sudden tornado would be predicted.  A special very low power
resonating rotating motor will be used to drive the rotating arm, and
special magnetic field lines collector will suck enough power to drive the
leds while rotating. The only requirements will be the arm rotation
direction, being clockwise in the north of the hemisphere and
counterclockwise in the south, due differences in the magnetic lines, but I
am thinking to incorporate a routine to do it automatically. The project's
name will be "LOO FLIR PA" regarding to the 92nd day of the year 2004.
