30th Chaos Communication Congress: http://events.ccc.de/congress/2013More Info on this DIY Pneumatic Tube System: https://events.ccc.de/2013/12/08/seidenstrasse/It needs an empty cut open spray can and a LED lightstrip (with a23 battery and holder) to be complete. You can get spraycans from us at the event - ask at the DJ Booth at Villa Straylight. Other then that you can fit a LED Strip behind the "Windows" in the top and there is everything there to wire it and make it even turn on once you put in the Spraycan.

Cool. Alright... It might be interesting to know that the description can contain working links, but the excerpt can't. Also, if there's a full YouTube video URL included, it will become an embed.
