WiiMote IR sensor and Arduino

http://www.stephenhobley.com

Movie clip of my first attempt at talking to a WiiMote/Pixart sensor over the I2C bus.

The Atmel processor converts the messages from I2C into serial, and sends them to the PC via a serial connection.

I put together a simple library for the Arduino here - http://stephenhobley.com/blog/2009/03/01/pixartwiimote-sensor-library-for-ard...

Based on the work of Kako.

How much cost that sensor and where can I buy it?

[shobley]

It's from a Wiimote - so about $39 from Wal-mart

Genius!!!......do you have any instructional guides on some devices?........patents?....et­c

@TheBlueThread you can ;D

What is really amazing, is that this sensor can track up to 4 blobs and that at an astonishing rate up to 1600 tracks/ second.

I've previously seen this sensor in action in the German computer club2 show (cczwei.de). There they used their own ATmega board for various projects.

A great camera chip for small money!

did you get rid of the 'classic' light sensor once you rigged the Wiimote sensor directly? I'm not sure what your galvo scanner speed is, but if you time it right, the two should not interfere with each other (causing flickering in your blob tracking).

Does your daughter track a flame as well as the Wiimote?

would kickass if you could use it as a mouse :D

great job, it's very interesting
