This custom coil gun for V2 robosapiens is outstanding. The video was posted to youtube over a year ago, but I just noticed it now, so let’s all just sit back, enjoy, and pretend it’s super fresh. Mmmkay?

It looks like Marcus based his coil gun on the bic-pen and disposable camera capacitor design that’s been floating around. To that, he added a servo controlled auto-reload mechanism, complete with a LED “armed” indicator light. The final package, with laser sight, should terrorize pop cans and Teddy Ruxpin with a half-Joule of kinetic robo-chaos. The CoilOsapien site below has complete build instructions, in case you’d like to make your own.
