I usually think poorly of home automation and smart homes. Not every thing has to be smart and should have an internet connection – especially not my coffee machine or what else. In this case, however, having a sensor which connects automatically to our wifi network and sends the achieved data to another server is pretty cool.

Wir genießen das Privileg in einer Wohnung mit einer sehr hohen Decke zu wohnen. Das Wohnzimmer in einen Minispielplatz umzubauen bietet sich also geradezu an.

Dinge gehen kaputt. Insbesondere mit zwei Kindern im Haus. Zuletzt musste unsere Salatschleuder an den Entdeckertrieb unseres Sohnes glauben.

If you want to reach websites on the Internet, all network traffic is usually routed through routers. Because no one can remember IP addresses for countless websites, DNS servers („Domain Name System“) are used to assign an IP address to a host name. A DNS server translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocol.

I am a big fan of laser shows. Good music, bright light, vibrant colors. And then there’s the technology: lasers, electronics, programming. All this became second nature to me. This virus already infected me during my early school days…

A while ago I had to take a hearing test at the doctor. The result of my left ear was unfortunately sobering, yet I found the measurement itself very interesting. To be able to continue to control my hearing ability, I wrote a program to measure the hearing threshold at different frequencies.

Because my brother bought a coffee machine and he wanted to brew the perfect espresso, he had to measure the amount of coffee powder relatively accurately. A cost-effective alternative to expensive scales was to build a precision scale from an Arduino, a load cell and a 3D-printed housing.

Wie vermutlich jeder weiß, senden Elektrogeräte beim Betrieb hochfrequente, elektromagnetische Strahlung ab (landläufig auch als „Elektrosmog“ bekannt). Insbesondere Bildschirme und die Abstrahlung ihrer elektromagnetischen Störstrahlung sind hier sehr interessant, da man aus der Modulation der abgestrahlten Strahlung unter Umständen Informationen darüber gewinnen kann, was auf dem Bildschirm gerade angezeigt wird.

A very light but nevertheless resistant Racecopter frame
I wanted to have a very solid but lightweight and yet simple fpv race copter frame.
This frame is incredible durable. This frame has even withstood several hard crashes so far. The frame may not be as light as a carbon frame, but the total weight of the quad is only 350g. With battery included 460g. That is truly not much for a durable and very fast racer. I would even say that compared to other builds, the quad is a flyweight.
