  • Schächental GoPro Fotos

    Yesterday I waited for the fog to disappear as predicted, but it didn’t happen. So today we went to Unterschächen in Uri where there is very seldom fog. When we arrived, I saw that WinWings were there just ready to dirve to take off. Sure enough they had a place left for me in the […]

  • RepRap part 3: Ethernet connection

    With the X and Z gears propperly glued, all axes moved. But it didn’t take long for the Z axis gear to break again. The gear that came with the kit was multilayered wood glued together and laser cut. The place where the belt is, is off the axle of the stepper motor. That’s obviously […]

  • RepRap Part 2 : It moves

    It’s been a while since I assembled the Gen7 Electronic board and the extruder. I ordered the extruder together with the steppers from the Netherlands. The hot end v6 is a very nice design compared to the original, where you had to wrap the heating wire around the nozzle yourself. But it’s too big to […]

  • My first night at a hospital

    Last time I spent a night in a hospital was when I was born moren than 34 years ago. I was never looking forward to the next one. But this weekend our son Levin hit the ground with his head really hard while playing. He cried badly, and the spot on his head that hit […]

  • Time Tracking with RFID on BORM ERP

    Before I discovered what my Bifferboard really is, I almost disposed it, but now It found a new purpose. It’s a networked rfid Terminal for time tracking on our BORM ERP. I use a simple python script on the device because it’s easier to experiment on a device where I would rather not compile too […]

  • Make an RFID tag with an AtTiny and a coil

    When I stumbled across this blog post, I was sure I have to try this at home. I had some interest in RFID for a while, but the Proxmark was too pricy for me just to play with. So this experiment came just right. The attiny85’s were difficult to get in Switzerland, so I ordered […]

  • Running debian on a nas dongle [updated]

    I used a nas dongle from ARP for a while to share an USB harddisk, and I always wondered about what’s inside. It’s a nifty little device that works reasonably well. It needed a reboot from time to time, and it had some issues with the filesystem. Because of the FAT filesystem it couldn’t store […]

  • Refurbishing our VW Bus camper van

    Refurbishing our beloved VW Bus camper van that served us so well on our great adventure in south america was long over due. After lots of offers and some setbacks, it’s finally going to happen before the rust wins. Last week, I spent two days tearing everything appart.Removing bumpers, windows, lights, mirrors, trims, bike and […]

  • Rendering Text in WebGL

    Just like OpenGL and most rendering engines that I know of, WebGL has no builtin support for text rendering. And on top of that, I can’t use the approach we use in PointLine at the moment. PointLine gets the outlines for the characters from the Windows GDI. So I was looking for something cross platform. […]

  • Is Windows 7 based on MS DOS?

    Yesterday I copied an InstallAware Project on the Jenkins continuous integration server. The copy always failed to build while the original succeeded. They were really the same at this point, so WTF!!! In the InstallAware forum I found out that the path name was getting too long. Well, yes, the name of the copied jenkins […]
