General questions

Can I use other Arduino versions? Sure, all Arduino boards should have the necessary pins available (as far as I know). I have choosen Arduino Nano as it's cheap, small, have FTDI onboard and the regulator can handle a bit higher current, compared to Arduino Pro etc. But pick whatever you prefer/have available.

Can I use other sensors? It should be pretty easy to use other sensors, as long as it's I2C. Update the sensor-init, sensor-reading and the sensor-configuration and you should more or less be good to go. I'll maybe add support for another IMU later.

Can I buy a headtracker from you? No, it's meant as a DIY project. It's easy to make, and it should be pretty straight forward. I like to develop, but care little about sale etc.

Can I sell this? Feel free. I can imagine a few people would like to buy a nice ready-made unit, but it would be great to know if you use my software/work. But in general it's uploaded with no strings attached.

What about copyright/license etc? It's uploaded as OpenSource, and I expect it to be used and abused - don't really see much sense in "protecting" my work. So feel free to use it for whatever purpose.
