Usefull stuff I found: How does NodeJS work?

This will be a very short article or rather a note and link collection on NodeJS. If you browsed through my blog, you have probably stumbled upon my beginner augmented reality project, where I wanted to create a real-time temperature and humidity monitor using Open Hybrid. Installing an augmented reality app on the Raspberry Pi Creating…

RetroPie: Moving my games to an USB stick

I wrote this article on the RetroPie setup some time ago, but I’m still getting a lot questions and comments on this topic. I actually thought that with the last couple emulator station updates came some improvements to this process. As I have not touched my system for quite some time, I simply do not…

Adding a motion sensor (hc-sr501) to my Raspberry Pi

As part of my “make my home a bit smarter” projects, I wanted to add simple motion detection via motion sensor to a Raspberry Pi. This is the first project with a hc-sr501 motion sensor I tried. The goal is to combine the sensor with an esp8266, but this is another project (as I’m still…

Ideas I’m to stupid to build: Sourdough incubator v2

How to build an Arduino based sourdough incubator

Why build an Arduino based sourdough incubator? Living in a foreign country usually leads to some challenges and some things you miss from your home country. For me this is good sourdough bread, which is pretty hard to get in Switzerland and kind of expensive. So since I’m cheap ;-), I thought why not make some…

Installing a DHT22 temp and humidity sensor on the raspberry pi

This is part of my series on creating my own augmented reality app, which I started here with the setup of OpenHybrid. I Like to use the DHT22 as an object, that I wand to control or read sensor data from. Therefore I have to install it first and make sure it is running correctly….

Installing an augmented reality app on the Raspberry Pi

Installing an augmented reality app on the Raspberry Pi? How did I end up playing around with augmented reality? I recently published a paper on the usage of augmented reality in marketing, finding out that there is no real marketing via augmented reality yet. As it became clear that almost all cases we had a…
