Nunchuck Connector

Does anybody know the pinouts for the I2C bus on the Nunchuck connector?

Maybe Google it or if you have an oscilloscope, use it and a meter to determine the pin-outs yourself.

Yes I have, I can't find it.
No, and even if I did have an o'scope, it won't do any good, the Nunchuck probably won't be sending out any data without a host requesting the data, and I can't make a host request data if I don't know which pins are the I2C bus.

BTW, I don't have a wiimote

Found a couple of links that might contain some useful information:

And the pinouts:

THANK YOU for that pinout link!

I've been able to create my own connector and now my microcontroller can report back all the data, It's awesome!

Also, WiiLi is a great wiki for this type of information.

Awesome idea, man! That's so cool. Are you gonna case Charlie, or keep him as the rat's nest? Oh, and by the way, bread board FTW!

I usually use a twist tie to bundle up all the wires, I don't like the idea of caging up a robot because I need to reprogram him a lot. But once I get more circuit board to use, I'll put the controller inside a nice project box so I can take it to places.

So these Nintendo connectors (which are used with different casing in the GameBoys and the 'Cube as well) are nothing more than a strip of PCB at the jack side?

no, that's the way i made them, it was just a improvise because nobody sells female connectors for the nunchuck, and the only other option was to destroy the cable to get at the wires from the inside.
nintendo can do better than that... come on... they're nintendo!

I know Nintendo makes them with plastic, I just wanted to know whether that really works well.
