Read wii nunchuck data into arduino

The nunchuck uses a proprietary connector. I just cut the end off of my nunchuck cable. The cable has 4 wires.
white - ground
red - 3.3+v
green - data
yellow - clock

Attach white to the Arduino's ground, red to 5 volt+, green to analog pin 4, yellow to analog pin 5. The nunchuck is only supposed to get 3.3+ volts. So far it has worked fine at 5 volts, but be warned. I am guessing that using the higher voltage will shorten the nunchucks lifespan.

Accelerometer

Accelerometer with arduino

I'm fighting with accelerometer at the moment....

Paper cup phone

it's very analog way to communicate to each other.

However, everyone knows what does do and how it works.

What if I use some recording input and random-play out put in same unit?

lots of thing will happen.

Nano Fabric

University of Pittsburgh researchers have synthesized a molecule that forms the first "nanocarpet," whereby
the nanotubes organize themselves into an expanse of upright clusters that looks like the fibers of a shag rug.
Moreover, unlike other nanotube structures, these tubes can sense their environment, change color and can be
trained to kill bacteria. The research aims at developing a paint that in the event of biological or chemical agents
being deployed would change color and simultaneously destroy the deadly substances.
