It looks like the Wii Motion Plus has been hacked so you can read the data via an Arduino. The build only requires about $4 in parts. Now that’s cheap! Check out the website for the schematics, code, and more information.
Alright, one great aspect about the Wii Motion Plus is its pass through port for other extension controllers such as the nunchuck. Unfortunately, no one has been able to read both an active motion plus and any other controller at the same time because they are all on the same I2C address(smooth nintendo). This is creates a large hurdle to people like myself who bought the WM+ to create a low cost IMU with it and the accelerometer in the nunchuck. After a good deal of digging and very little luck, I did find a way to use both at the same time(though not through the pass through port). And best of all its cheap!

Soon to be deployed as part of the Atmospheric Neutral Density Experiment test program, the Pollux satellite carries student-designed payloads built with Arduino –
Westfield High School accelerometer payload: This payload uses the Atmega16 microcontroller and measures the voltage of three SCA610 accelerometers made by VTI Technologies. The accelerometers will be used to detect rotation in three axis. Software was developed using the Arduino software which makes programming in C/C++ easy.
Marshall Academy gyroscope payload: This payload also uses the Atmega16 microcontroller and Arduino software. The payload collects the rotation rate and temperature from each of the three Melexis MLX90609 gyroscopes. The 75 degree/sec version was selected to support measuring rotation rates up to 12.5 rpm.
Federation of Galaxy Explorers Gyroscope payload: This payload also uses the Atmega16 microcontroller and Arduino software. The gyroscopes are Analog Devices ADXRS401 75 degree/sec devices. Also included in the payload is the PNI Corp. MicroMag3 3-axis magnetometer.(I’m guessing they meant to say “ATMega168″, instead “ATMega16″ ?) Read more on the project on the Stensat Group’s site.

I thought you guys might like to check out my latest project. It’s a pair of musical MIDI-enabled sneakers. You can use them to trigger sounds/samples, or control pretty much anything that you can connect to a computer or Arduino. It’s a relatively straightforward project, and has tons of potential for expansion and modification.
