Sebastian Dehne's Blog

I’m an electronics and computer enthusiast who is currently employed at Systek and works for the Norwegian tax office. At work I design and build large-scale, highly available software systems and in my spare time, when not working or spending time with my lovely family, I design & build electronics projects. I’m also a licensed ham radio operator and my callsign is LB3OJ.

This is my personal blog on which I will typically post all kinds of things that keep me busy in my spare time. Although mostly related to software & electronics, I might also share photographs or other content from time to time.
