Yesterday I saw the recordings of the talk from Christine Spindler on the 35c3 about MicroPython, which was great by the way. I heard about MicroPython before and had already looked into it. Because I have a MicroPython capable board lying on my bench, I will play a little with it. So let us install … Read more
Over the last weeks, I was building a moving robot platform with OpenBeam aluminum profiles from https://www.chartup.com. The platform should serve as a base for future development with the Raspberry Pi and OpenCV. Therefore I got a nice OpenBeam kit with different aluminum profile lengths. For the fixture, I’m using the metal brackets from the kit … Read more
So my Prusa i3 MK2 is printing just fine and I get awesome results with PLA and nGen. But two things are missing to be a perfect printer which is living room compatible. The y-axis in comparison to the x- and the z-axis is really loud. A few days ago I read on the Prusa … Read more

Introduction I tried to install NodeMCU on an ESP8266 with the help of my article from January 2015 but I had some problems to do so. So I write a new article with a new approach, which works today. Connection For the connection, we need a serial interface. I use an FTDI UM232R module for … Read more
After printing a good amount of filament with the GRR Neo, I’m really happy with a 3D printer as another tool in my drawer. So the investment was worth it. From time to time I’m printing a part from Thingiverse, but mainly I print parts I created by myself. Creating your own part is most … Read more
For this year’s Holland vacation I bought a little gadget for my camera. It’s called a Flow-Mow and lets you take moving timelapse recordings. The Flow-Mow works like a mechanical kitchen timer. You mount it between your tripod and the camera. Then just wind it up and it starts slowly turning. So while you take … Read more
