Game modding with pen and paper

I have lots of good memories from youth camps. Some involve playing Donkey Kong and Mario Brothers while sitting on trees. Another classic video game was Asteroids. When I recently read an article in a German magazine about building an Asteroids clone with an Arduino and an OLED, lots of old memories resurfaced. The source … Continue reading »

AtMega breadboard header

A while ago, I ordered some AtTiny breadboard headers from tinkerlog.com. Unfortunately, they didn’t have any boards for AtMega’s left. The ones for the AtTiny’s are very handy, and I used them whenever prototyping something with an AtTiny. In fact, I used it almost whenever flashing an AtTiny. Many times I wished I had one … Continue reading »

Adding a display to rfid time tracking

More than a year ago, I blogged here about using RFID to track presence times in the BORM ERP system. I used the system a lot since then. But the BlinkM was really limited as the only immediate feedback channel. To use it with multiple users, a display was needed. The default Arduino compatible displays … Continue reading »

minimalist lasershow

For a long time I marvelled at sites with self built laser shows. There is truly amazing stuff out there. But most of them look like really lots of work. And with simple commercial units getting cheaper, I don’t know if all that effort can be justified. So I had a look at the commercial … Continue reading »

LED debugging the stereowrap hardware

I found out earlier that 5V is not enough to drive the shutter glasses. With my breadboard setup for stereowrap, I fed 12V to the op amps from an external source. Now that I moved the thing to a strip board, I added a step up converter that generates 12V from the 5V available on … Continue reading »

Reviving my vintage 3d shutter glasses

Many people don’t even know that there were 3d rushes before the one that’s currently fading. In a previous one, some ten years ago, I bought a very expensive ASUS graphics card with shutter glasses. It was really cool for gaming with the 21 inch CRT, but nothing compared to the graphics of today’s games. … Continue reading »

Arduino code to interface the MS5607B Intersema barometric pressure sensor through i2c

It was not quite as easy as I anticipated to interface the MS5607B sensors that I had sitting around for quite some time now. Sure, wiring them up is a lot easier. Although I still don’t like soldering SMD. In the end, it worked out, and the code can be downloaded with the links below. … Continue reading »

Arduino Code for the MS5534C Intersema pressure sensor

After receiving personal messages on the arduino forum asking for the code for the Intersema pressure sensor, I paste my code here. It is based on the code from Hari Nair for the open source solar vario that I bought from him.

Weatherstation problem

The plan was to build a mobile weather station with an arduino, two old windspeed sensors from the local paragliding school, a temperature sensor, a solar panel and an old cellphone. As the first part I wanted to read the anemometers. I got them for a bargain from Touch&Go. Only I couldn’t figure out how … Continue reading »

Handheld 2.4GHz Spectrum Analyzer

Finally I got my Spectrum Analyzer to work. At first I was curious if I could use the display from an old Nokia cellphone I disassembled in conjunction with the Arduino. So I was looking for anything that could help me in doing so. Then I stumbled across Miguel A. Vallejo’s Handheld 2.4GHz Spectrum Analyzer. … Continue reading »
