Hi, and welcome to my playground. I'm Thomas and on this page I write about my hobbies; electronics, microcontrollers, programming, computer stuff and pretty much anything I find fascinating.

User page: My homelab New

I’ve had a server rack for quite a long time, I first got it back in 2011. But I didn’t really go all in, I basically just used it as a shelf to put some computer equipment. Well, lately I’ve been doing a lot more than that! The homelab rack sits in my home office, just left of me as I type this text. Because of that I’ve been focused on keeping the noise as low as possible; for that reason I’ve built the computers myself instead of buying second-hand rack servers. I’ve tried, but they sound like turbo engines.


Blog post: Keeping it simple stupid New

I first started writing code for this site over three years ago, and during that time I’ve added and implemented a lot of functionality. But lately I’ve been doing the opposite, I’ve been removing and simplifying. It all comes down to priorities really; time is a luxury when you have a full time job and two (soon to be three) kids. So I want to focus on things that are productive, and of course fun!

Who am I?

I am Thomas, and Hebron, a programming and electronics enthusiast. I've been doing electronics projects for about 10 years, using the AVR micro controller. The last couple of years programming has really peaked my interest, especially C#, Python and PHP. I live in Norway with my girl friend and our two twin boys.
