Doing It Yourself isn’t always the easiest or cheapest option, but odds are you won’t find anything more satisfying than finishing a DIY project with your own two hands. Each week, we’re going to showcase one cool DIY project tutorial from around the web.

Making things out of spent bullet casings is kind of a pastime of mine, but Igor from Inspire To Make is taking the entire process one step further with his DIY Bullet Casing Headphones. You might be saying to yourself “I feel like I’ve seen something like that before,” and it’s because you have. There are plenty of pairs of earbuds on the market that look like they’re made with bullet casings, but most of them aren’t actual bullet casings. If you want to make your own pair with real bullet casings you’re going to need some tools, materials and soldering skills, but the tutorial on Inspire to Make will walk you through the entire process if you’re daring enough to pull the trigger (had to).
