Somethings with money...Hackerspace Hack42: the adults' playground! Engraving cookies with lasercutters, 3D-printing, woodcarving with a CNC mill or drillpress, opening locks without using a key, drinking Club-Mate at the bar or admiring our special collection in the computermuseum.Lots of things to see and even more to do in our Hackerspace. Part of which has been dedicated to the computermuseum. We have electronics labs, crafts and fabricating labs, we have a cosy lounge and bar, a gaming room and more! If you are even slightly into computers, crafting, electronics, tinkering and/or engineering, you'll find everything to your heart's content and more on all sorts of skill levels. Not everything we do is related to computers and even if you do want to do something with computers, you don't have to be an expert! Novices are just as welcome as experts, making mistakes is part of the journey and learning together if fun!
