This is the end of this project, what you find here is the only information I can give for you. I will not support this project anymore (I was inactive long time now so not a supprise).

Please everyone handles the project informations with care, this is not an Instructable! You will not find step to step information about how to make these devices. Most probably you will need debugging and higher electrical skills to develop your own from this. Some of the libraries are updated since I have made my arduino code and the original code which is still posted here is may not work how it was intended to!

Good luck for everyone!
