A friend of mine at uni did something like this for his 4th year project. He originally had the wiimote connected to his macbook and was reading the data in and converting it to something to transmit via a serial link to a PIC. He got it working quite well, so him and another friend took it one stage further!
They got a usb network host and installed linux on it, put the wiimote code on a flash drive and a bluetooth dongle in one of the usb slots of the host. There was a serial output on the host so they were able to connect that to the PIC. This gave them an all in one device.
unfortunately there are no videos of it working as an all in one unit, but it was quite cool.
yeh, i know. There were some videos/pictures of an early build, but they were lost in a harddrive failure. We'll be documenting our helicopter rigorously, so no need to worrd about that!
Imho, I don't think you get the Bluetooth & HID stuff running on a micro like AVRmega or PIC. For these you need a little bit more power. A gumstix board (ARM processor with Linux) for example can do this job.
That is just too cool!!
Too bad he just skips over the part where he tells about how he made the interface.
Wouldn't you just need a bluetooth module that hooks up to a micro?
All you'd have to do is find out what security code the wiimote uses to connect, and then program that into the bluetooth. Most modules have their security and connecting programming all within the module.
Is this what you`re looking for?
and $4 is a steal because of the crappy AUD right now.
