Some of you might have already seen the #Stonehenge soldering challenge. It will return to #39c3 and be available in the #hardwarehackingArea

Its a cursed soldering challenge that will test your skill. The CH32V203 µC make programming accessible if you want to tinker with the software.

There is a workshop where you can build it on site with help from Kliment and other awesome people.

Or just get a kit and build it at your assembly or at home.
