A quantitative update of the parking demand in Marburg during the Corona pandemic 2020.

In this article, I use machine learning to predict the number of parked bikes in two ways.

I use quantitative analyses to derive social and environmental benefits of the Nextbike system in Marburg. Also, I investigate which routes in Marburg are popular among Nextbike users. Hence, I offer quantitative arguments as to why bikes are good for Marburg and how to improve the biking experience in Marburg even further.

In this article, I draw quantitative conclusions for cyclists who use Nextbikes in Marburg. For these quantitative conclusions, I use Nextbike data that I previously scraped.

I collected Nextbike data in Marburg and introduce my plan to evaluate the data in this article. Also, I present what the data is made up of and how it is obtained in detail. Lastly, a first temporal analysis of the bike usage in Marburg is presented.

I show my small K40-based hobby laser cutter setup. I include one bonus tip: How to make money with a laser cutter.

A list of small designs like 3D prints, laser cuts and other constructions. Most of them serve a functional purpose. This list is continuously updated.

A laser cut community gift for Xournal++ developers.

I show how to use 3D scanning for CAD modeling and how I built a custom PC mouse box with the method that I present here. Neither do you need a GPU nor a powerful PC to follow along this tutorial. Also, the 3D scanning software is for free.
