Electronics is my main hobby. On the following pages are projects I made starting in the late 90's to the present day. Some are finished prototypes and some are a working proof-of-concept.

A few of my favorite projects

µSERVER

One of my favorite electronics projects is a tiny web and ftp server built with an 8bit ATMEL AVR.

WeatherDsiplay

This is a stand alone WiFi weather display that also features UV and moonphase data. It is featured by an ESP8266 with custom firmware an an AVR. Firmwareupdates for AVR and ESP are provided by a single USB port also used to power the system.

16x16 LED MATRIX

This is a 16x16 LED matrix. It is made with an AVR and the C++ software features a tetris, snake, Conways game of life and a few more. A PS/2 keyboard is attached for controlling.

WINAMP CONTROL

This is a prototype that implements the concept of a physical progress bar for Winamp (PC). It was published in the Elektor magazine for hobby and professional electronics in the January 2010 issue.

USB POWER MONITOR

One basic need of a computer scientist is to measure the power that a USB device drains off the PC. This device is plugged between the PC and a USB device and displays the current on an LCD.

LOGIC INSULATOR

After I had a little misshap with my Saleae Logic that ruined the analyzer and parts of my PC it was clear that some galvanic protection needed to be implemented. This ultra compact device plugs directly in the Saleae 8bit Logic and galvanicaly insulates it from the testcircuit.

MSP430 MICRO TETRIS

This is a little Tetris game. It is built with a Nokia 5110 cellphone LCD and a Texas Instruments MSP430G2553 microcontroller. The system without the backlight uses less than 1mA. It is written in C++ with the TI Code Composer Studio.

AIR

There are many universal remote controls out on the market. None of them have the style of a GameBoy Advance fitted with a little infrared transceiver and a functional C++ programm.
