Wow, what a weekend. Last Saturday and Sunday, our team set up a booth at the Open Source Hardware Summit 2026 in Berlin, Germany. The conference was full of interesting talks and fascinating workshops, where we learned how to solder and make shiny jewelry from just a battery, wire and a couple of LEDs. The summit featured many small and medium size manufacturers of open source hardware products ranging from a fully wooden percussion set to hand-made running shoes and sneaky TV-B-Gone remote controls that can turn off any TV from as far as 50m away.
