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.

A fistful of projects

I/O module driven by a computer parallel port

Get 5 inputs and 8 outputs from a computer printer port using only a few transistors and resistors.


Alarm disabling unit for production equipment with long stop warning

Simple unit to silence the audible alarm on a production equipment, additional warning if not resolved within 30 or 60 minutes. Uses an AVR ATtiny2313 microcontroller.


Programmable keypad with two modes

Keypad with programmable PIN code, two outputs (modes) and protection against repeated incorrect PINs. Uses an AVR ATtiny2313 microcontroller.


A pick from our articles

A first look at my workshop/man cave

I finally have a workshop again; that also doubles as my man cave. Let me show you around :)


Getting started with the AVR microcontroller series

A quick introduction to the AVR microcontroller series with sample schematics of inputs, outputs, serial and some basic circuit drawing.

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.
