I'm a 22 years old tech enthusiast from Germany. By day, I'm a production test software engineer for high-speed AWGs at Keysight.
By night, I like to hang out with fellow hackers from the Chaos Computer Club.
You can see my other interests down the page.
I got into 3D-Printing in 2017 when I bought my 3D-Printer, an Anet A8. Since then I printed many parts to tune my printer
as well as many beautiful things like the two Baby-Groots you can see in the image below and functional things for me and for friends
like car parts or an actioncam mount for my ski helmet.
Since I heard about being able to recieve all radio frequencies up to 1.2 GHz with just a very cheap USB dongle back in 2014 I am very fascinated by poking around the radio spectrum, listening to amateur radio operators and decoding various signals.
Examples are flight data (ADS-B), RTTY and WeFax weather forecasts by the German Weather Service, weather ballon (Radiosonde) data, and images from weather satellites such as NOAA 19 or Meteor-M2 which are orbiting the earth in a lower earth orbit, in these cases at a height of about 850 km. You can learn more about this whole topic at www.rtl-sdr.com.
Here you can see an image from Meteor-M2 that I recieved and decoded myself:
Since I saw someone creating airrings at my local open-air swimming pool many years ago I couldn't forget about seeing this until I had the idea that there must be tutorials on YouTube on how to make them about two years ago.
What I found was this and this video.
After two years of practicing you can even do some "tricks" like these two airrings fusing together:
