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.

Newly published projects

Warning lights with 10mm LEDs New

Four very simple LED warning lights, with a total of 10 LEDs; 2x2 and 2x3. The yellow LEDs have four chips, making them pretty bright. And with a 40 degree light beam they are quite visible, even more so at a distance. So they make pretty good warning lights. Powered by: 12-13.8V.

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. Read more on my profile page.
