In my free time I've been playing around with an Arduino MEGA. Besides that I've been a solid Linux user for over 5 years.
I'm very enthusiastic about tinkering with hardware, software etc. In fact, if you look at my youtube profile (http://www.youtube.com/user/zandaa) you will find videos of my first steps with the Arduino and electronics in general.
When it comes to programming I've been working with Java and bits of C, C++ and C#.
