In 2013, I organised the second Photonik-Camp in Aachen. This time, the participants had to create ideas for the first Makerfaire in Germany. The best ideas got some funding and became part of the Makelight booth at the Makerfaire Hannover. I recorded some talks:
Merlin Schaufel: DIY Diodenlaser
Merlins presents his DIY laser cutter that uses a laser diode.
Markus Lenz, Stefan Kray: Lasergame
Markus and Stefan created a game with galvo lasers.
Roksy: Agent Light
Roksy tells the story of Agent Light.
You can find more information on the official website and a report on the Photonik Campus page.
