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.


Kitchen cabinet lights with 10mm LEDs New

In my old apartment, and before LED lights were cheap and everywhere, I build my own LED down-lights and put then in my kitchen cabinet. Two lights, each with four warm-white 10mm high-intensity LEDs, and a simple fuse and switch box. Powered by a 5 volt AC adapter.


Bias lighting for TV using LED-strip New

Bias lighting is, simply put, to light up the wall behind a monitor or TV. This creates a glow around the screen and, supposedly, creates a more comfortable and high contrast viewing experience. I made my bias lighting simply by sticking a LED-strip behind the TV.


A pick from our popular projects

Mood light using 3W Prolight RGB LED

A 3W Prolight RGB LED mounted on a heat-sink, with rubber feet to support e.g. a glass ball.


Emergency strobe light

33 high intensity LEDs are controlled with a AVR ATtiny2313 microcontroller. Four flashing patterns that can be set manually or cycle through.


Fan and temperature controller with LCD

Reads temperature and controls a fan using a PWM output, fan and alarm set point can be adjusted and is shown on a LCD. Uses an AVR ATmega8 microcontroller.


Sound alarm controller

Simple unit to control three sound signals; beep, siren and buzzer. Uses an AVR ATtiny2313 microcontroller.


Lync presence (busy) light

Let your coworkers know your availability with this simple Arduino Uno project. Three LEDs that reflect your Lync (Skype for Business) status.

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.
