Running Electrical Conduit Using FreeCAD and 3D Printing
The great thing about having a 3D printer and open source CAD software is the ability to make accomplishing projects easier. In short, I had some electrical conduit to run and I wanted to mount it along a steel structural I-beam in CubicleLabs.

Hackaday Berlin Was Bonkers
In celebration of the tenth running of the Hackaday Prize, we had a fantastic weekend event in Berlin. This was a great opportunity for all of the European Hackaday community to get together for a few days of great talks, fun show-and-tells, and above all good old fashioned sitting together and brainstorming. Of course there was the badge, and the location – a gigantic hackerspace in Berlin called MotionLab – even had a monstrous laser-eye octopus suspended from a gantry overhead. Everyone who came brought something to share or to show. You couldn’t ask for more.
