I posted on here a while ago that the wii motion plus gyro sensor had been cracked but didnt really get much buzz about it. Well one problem with using the M+ in addition to the nunchuck to supply the accelerometer is that both are on the same I2C address. I found a real easy way to get around that problem and now the possibility opens up for a $40 6 sensor system. Now, I love that diydrones is offering an IMU system now to play with, but being a poor college student I cant shell out over $100 bucks for a new toy. I believe using the nintendo parts serves a completely different crowd of people that want to experiment, on the cheap, and with something that they could easily use in a wii (if they have one) or sell for at least a 50% return. Check out my blog for details and code.Also, Im taking the plunge and making a kalman filtered 2d IMU in a little bit. It should be done soon. Many thanks to Jordi and the Kalman code he posted near the inception of this site. Its been helping me see a little more practically what a Kalman filter means.

Wii Motion Plus Decoded

Hi everyone, Ive been a member here for a while and though Ive gotten a lot out of following along with all the great projects here, I havent really had much to contribute back (aside from referring friends). Well now I do! I posted this over at the arduino forums but I figured it would have a lot of impact here too: I have successfully read the gyro data from the Wii Motion Plus peripheral. I posted code and some additional info on my shiny new blog: here and if someone can tell me how to post code on diydrones, I'll gladly post code here too.
