In nice contrast to the seriously organized Techshop, I paid a visit to the more anarchistic Noisebridge. It is one of the most famous hackerspaces around, and they have pulled of some very nice projects. Check their web for more info on projects. It was quite a nice feeling to arrive as a stranger in the city and have full access to the soldering equipment I needed to get my hexacopter flying again. So in return for the free service and helpful advice, I made use of their donation box.
