Bunch of dragons hiding in a labcoat, were at the W7-x and now interning at CERN! Happily pro-nuclear but still students, big time nerds AND love glowy stuff?? What could go wrong!

We love working on anything nerdy and electronic, ranging from ESP32 and STM based systems to tinkering with Ruby scripts, databases, a bit of smart home here, a bit of PCB design there~
