 <p>For students, COVID-19 and the associated homeschooling and isolation meant one thing above all: a lot of time. They used it in different ways. I used it to pursue my new hobby intensively. During this time, I learned new programming languages like Java (partly for Minecraft plugins, <a href="https://git.privacynerd.de/BlueFox/MC-Plugins">here</a> you can find some), and even taught myself some C and assembler.</p>
 <p>During this time, I was given my first Raspberry Pi - with far-reaching consequences. Because it led to me turning more and more to the hardware side. While I had previously written web apps with a database in <a href="https://www.djangoproject.com/">Django</a> or <a href="https://flask.palletsprojects.com/en/stable/">Flask</a> and Python, I was now programming simple blinking circuits, then at some point scripts that read sensor data and displayed it on a small OLED display (0.96&quot;) or switched the lamps in my room on and off at the touch of a button (because a light switch is not enough!). During this time, I also discovered for myself a 3D printer that had been sitting around almost unused for a long time.</p>
