Hi, I got a 700D, 750D and a 760D, plus some very basic knowledge of programming in machine code, ASM, C++, and misc other languages. (My main skills are not embedded software but mainstream languages like Java, C#, JavaScript, asp, HTML, asp.net, SQL which I guess will be useless here?).
I also has some experience with building or modifying hardware/electronics, for instance I've built my own timelapse dolly with integrated circuits controlling my cameras.
I've been using Magic Lantern on an earlier 500D and currently on my 700D and love the extra functionality.
If you need testers, I would be able to help :-)
