In den Schlingen der Doppelhelix

20 January 2019

Die im Labor erschaffene Laka ist bereits bei ihrer „Geburt“ nur ein unnützes Relikt einer längst untergegangenen Zivilisation.

Orbital Distance Speed Intuition

3 June 2021

Or something like that XD I was discussing with a friend the deltaV requirements to fly to the Sun (~30km/s) for a simple route and we struggled a bit to intuitively grasp, why this requires more energy than leaving the solar system (which is a much bigger distance). But in space, distance does not matter. […]

Generic Webcrawler

Do you sometimes have the issue that you have to come back to a webpage to see if an update is finally there? While many websites let you register for an update if a product is available again, most sites do not offer this service.In my particular case I was searching for a fixed parking […]

River Table Epoxy Edge

River Table

29 September 2020

If you have spent some time on the world wide web, you most probably have seen at least one rivertable. They look simply amazing and the natural beauty of fluid dynamics, frozen in time is simply astonishing. The output depends mostly on chaos, where only some input variables can be tweaked. This was love on […]

Fourier Fun

26 September 2020

Have fun playing around with the speed and the amounts of circles to create beautiful graphs 😉 While I often had to work with Fourier Transformations in the scope of computer vision and also during my master thesis to analyse electromagnetic frequencies, most of the times I simply used the equations, without thinking to much […]

Low Level Home “Automation”

Like many humans and all Nerds, I really enjoy to place my life into metrics and keep an overview. Since my gf and I started making mead, it was of interest where we could store it during fermentation process. For that the temperature needs to be at least above 15°C and so we placed a […]

Drone Photography

5 July 2020

What I like most about photography, is the capability to show somebody the world through different eyes. The most exciting areas are, where you show something in a way, humans can not perceive them. Like a long exposure time to draw with light into thin air, or super short shutter times to visualize processes which […]

Interactive Corona Dashboard

10 March 2020

When the Corona epidemic reached Germany I got interested in the visual representations of the pandemic and was surprised that most awesome of them all, did not have a higher granularity for Europe than just the countries.

Calculating amount of colorization for a psychological study

21 July 2019

Augmented Reality App with Unity and Vuforia

19 May 2019

Bitcoin Gold Visualisation

1 May 2019

Recently I was wondering how much gold a Bitcoin is currently worth.I calculated that it would just need a coin, little bigger than a 2 Euro coin. Since this is an easy calculation, but can be a good visualization of the worth of a Bitcoin, I created a dynamic representation of it in Java Script. […]

Inside of a credit card

18 April 2019

What do you mean? Inside of a credit card?It’s just a sheet of plastic. There is nothing inside, you might think.But credit cards embed actually a tiny computer!The golden chip you see on the front, is basically the same as the simcard in your phone. Just running different software. Opening the card I had an […]

Money is Time – You pay with your time

Everybody knows the phrase “Time is Money” but its also the other way round! I was often curious how long I need to work to pay for something. Mostly small things like a coffee or a ticket to the cinema.Since I am lazy and don’t want to do the calculations each time by hand, I […]

HTML Games with

Last year a friend of mine had his 30th birthday, and on the search for a present I discovered Phaser. A free and super fun framework to quickly create browser games. Since he is a big fan of the anoying screeming chickens, I created a flappy bird version of it, which you can play here […]

Brightness values of images as 3D topology with Python

5 February 2019

I am still not sure why exactly, but yesterday an idea came to my mind at did not let it go until I wrote a small python script to make it happen.The idea was inspired by some Art of 3d cubes showing an image, minecraftstyle, where the topology was defined by the color brightness. It […]

3D printed Phone holder

21 January 2019

Last year I had the issue that I wanted to send a phone with a tripod to Mars in the scope of an experiment for the analog astronaut mission AMADEE-18. Since volume and weight are both critical for the stability of the tripod, but need to be as small as possible for space missions, I […]

Delta Robot

21 January 2019

One of the projects I did during university was called “Assesment and optimization of magnetic torquers for spacecraft attitude control“ This involved the conception and development of an automated test stand. After some research I decided to build a delta robot, due to his big working area and smooth movements in comparison to a cartesian […]

100 days in Asia

20 January 2019

This is my travelblog that covers my trip to south east Asia 2015/2016. The whole story is whopping 46 000 words long (1.5 times like famous works as Hamlet or Animal Farm) and contains hundreds of pictures to allow you a hopefully good insight into the countries/areas and my way of traveling. You can see the 33 000+ km […]

Quantum Mechanics in Space

20 January 2019

In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferometer, with the arms distributed between a single Earth orbiter and a ground station. By compensating for other degrees of freedom and the motion of the orbiter, this setup aims to […]
