Illustration for article titled DIY Rail Gun is Terrifying, Comes with Building Instructions

How have I not seen this project before? It may not be quite as powerful as the Navy's, but this DIY rail gun packs 5.6kJ. That's five point six kilo Joules of Oh-my-dear-sweet-Geezuss-I'll-never-piss-off-a-DIYer.


The rail gun seen in the video below is only the first revision Ravi Gaddipati's project. The next one will be capable of "forty caps each rated at 400v and 3900µf." Holy crap! I'm not even going to question why he's building one of these. I'm just excited that there are plenty of pictures to walk you through the process on his site. [Vimeo via RP181 via Make]
