Tech project blog of Bastian Raschke

About us

Sicherheitskritisch is my blog and platform to present and document ongoing private projects. Most projects are related to any of the following topics: smart home, smart lighting, DIY, hardware, security or Linux.

I started the blog together with my friend Nils in 2014 with only German articles, but realized the international interest of some projects (especially the fingerprint sensor project), so I decided to translate some popular articles to English and write upcoming only in English to reach a bigger audience.

The motivation of writing the articles and document the projects is simple: I like my projects and most of them I use in daily life. But I think it would be bad if the experience and impressions I learned while building the projects is not shared with other people (you!). Maybe some people get inspired here and/or motivated to do some own stuff and this would be great! So checkout the projects and start some own if you want! 🔧💪


Bastian Raschke

I studied computer science (internet-based systems / secure and mobile systems) on the University of Applied Sciences in Trier. I like technical stuff since my childhood – I always wanted to know how gadgets work, so I disassembled a lot of them. Nowadays I'm able to build my own gadgets running my own software.

I'm a pragmatic person, I like to create something instead just talking about it. And I want to give back a bit of my experience to motivate people to create some own projects!

I studied computer science in Trier with Basti. Because I also like to spend my free time with technical stuff, we started this tech blog. Besides the technical topics, photography is a big hobby of me. It helps me to stay in balance and perfectly fits to my wanderlust.

Apart from that I'm a normal guy, most times in a good mood and like to do sport like jogging. I also play an musical instrument and like to meet new people.
