Iron Man‘s arc reactor is one of the most popular Marvel cosplay accessories, instantly transforming any outfit into a Tony Stark costume. But while you can buy a range of replica arc reactors online, the idea of building your own can seem a little intimidating.
Unless you’re this guy.
Redditor iltl64 posted photos of an impressive homemade arc reactor this weekend, built almost entirely from household garbage.
“I don’t have access to a 3D printer or really any special tooling,” he wrote on Imgur, before illustrating a DIY process that mostly revolved around cardboard, a tuna can, and an old Samsung phone battery.
The most technical aspect of iltl64’s build was soldering copper tape to build a rudimentary circuit board on the front of the arc reactor, connecting the ring of glowing blue LEDs.
The end result looks a little clunky, but if you wear it under a t-shirt, it’s perfect. And since the first arc reactor was thrown together from spare parts in a cave, we think Tony Stark would approve of this fan’s DIY spirit.
