Jumping ship as google is getting evil
For many years google stood out of the big IT enterprises as an example of respecting their users and embracing open standards. Sadly, they are drifting away from that, and it looks as if they want to get as insidious as the others. Gone are the times of “do no evil”. Just recently, I wanted to […]

Jaguar headliners repair
Remember the Asterix & Obelix comics, and that the only thing they feared was that heaven would fall on their heads? That happened to me lately. But it was not as bad as that might sound. Well, the joke doesn’t quite work in English. In German, we call the headliners of a car “heaven”. Last […]

Variable fan speed for the camper
The T3 VW camper vans came with a three step fan speed switch. Maybe it broke just like that, or maybe it was due to the kids playing with it endlessly. No matter what, the broken switch was a good opportunity for an upgrade. I ordered a 15A PWM motor speed controller which I thought […]

This Easter weekends the weather was really crap, so we stayed home. We had lots of time to spend with the kids, and we all enjoyed that. The boys are still a bit too young for the projects I usually do, but we just did our first electronics lession.. Even if Levin didn’t fully understand […]

BitCoin hits CHF 100 mark
Yesterday one BitCoin was, for the first time, worth more than CHF 100! When I first learned about BitCoin in early 2011, CPU mining was still enabled in the default client. I mined for a few days, but it was probably already too late for the CPU. GPU’s took over before that. Last year, you […]

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 […]

Wallis Ski Holiday
Last week we spent a ski holiday in the Wallis. We stayed with Mirella’s mother. Most days we went to Bürchen to practice skiing with Levin, and have some sledge rides with Noah. Levin went to the ski school for half a day, but he didn’t like it at all. He preferred being taught by […]

GPGPU programming class
It’s already a while back that I completed the coursera class “Heterogeneous Parallel Programming“. It was mainly concerned with cuda, which is Nvidia’s GPGPU framework. GPGPU is about running common computations on the graphics card. The class also quickly covered OpenCL, OpenACC, C++AMP and MPI. In the programming assignments, we juggled a lot with low […]

Skiweekend in Hasliberg

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 […]
