In a Medium post, Hackerloop’s Valentin Squirelo thoroughly documented the build, which used a combination of custom 3D-printed parts, Arduino-like electronics, a couple of electromyography sensors to detect muscle movements, and a pair of Nerf Swarmfire blasters whose round design made them perfect for this hack—although hunting them down was apparently the hardest part of building the prosthetic.

A lot of the time, custom builds like this end up looking a little thrown together as the creators are more concerned with whether or not they can actually pull it off. But the custom 3D-printed sheath and casing created for this prosthetic not only look like something out of a Mega Man game, they also help to hide all of the underlying electronics and mechanics, which, you don’t actually want exposed to flying darts in the heat of battle.
