5 Desperate People Who Hacked Junk Into Lifesaving Devices

While prosthetic limbs are of course available in China, they're generally accessible only to those who consider themselves too good for homemade bomb fishing. So, after eight years of guiding his two nephews' tinkering, Sun managed to perfect a pair of honest-to-goodness steampunk bionic limbs. Constructed of steel and operated with his elbows via an intricate series of wires and pulleys, he's once again able to do just about everything you can do with actual hands, such as grasping, holding, and choking the life out of his enemies.

They work so well, in fact, that Sun and his nephews have started constructing prosthetic limbs for other similarly unfortunate folks. That, or they're building an army bent on world domination.

Oh, did we mention he has his own Evil Dead II attachment?

Generally, to hold down a job, one has to show up to work. If you don't have access to cheap, reliable public transportation, your own vehicle, or really, really strong legs, you're out of luck. Homeless Brazilian man Orismar de Souza vowed to do something about that. He starved himself for months, saving up every last panhandled penny to accumulate the several hundred dollars needed to stock up on scrap metal. Then he -- a man with absolutely no former experience in metalwork -- used a borrowed hammer and chisel to fashion a pile of raw metal into a viable mode of transport.

Now, this ain't no Lamborghini -- powered by a measly 125cc motorcycle engine that de Souza scavenged from a junkyard, it manages only about 50 miles per hour on its best day. Still, the car has improved de Souza's life exponentially. Thanks to his newfound mobility, he was able to land himself a job in the local sugarcane fields.

Let us reiterate -- it took him four years, but this man built a car from scrap metal using literally the two oldest tools ever. Affectionately dubbed the Shrimpmobile, the car has all the required equipment to make it street legal, including lights, mirrors, and bitchin' flames. The Shrimpmobile also boasts a comprehensive list of safety features, consisting of:

1) It's painted neon lime, so you can see it coming.
2) That's it.

Next, he built a generator from a rusty voltage stabilizer, which may as well be a flux capacitor for all we understand of it. Why does a teenager need a generator? Well, when he's not MacGyvering complicated electronics from shit he found in the garbage, Doe dreams of being a DJ. Most DJs these days simply don some ironic sunglasses, show up at a bar, stand in the corner, and open up iScratch on their MacBook. Doe had to cobble together his own FM radio station just so he could spin there. Now Doe not only entertains the entire neighborhood, he even employs his friends.

He has been called a technical mastermind by MIT and Harvard, and the former honored his talent by making him the youngest person ever invited to their Visiting Practitioner's Program. Just imagine what this boy-genius will accomplish when "adequate funding" means something more than "finding a broken radio on the curb" and electricity is a reliable factor, rather than a novel surprise.

Baez roots through the local garbage dump and assembles the trash he finds into incredible farming machines. One of his most successful contraptions is a crop fumigator that has reduced fumigation time from six hours to one. Plus, it makes you look like you're being attacked by a sentient penny-farthing, and that makes it A-OK in our book.

His other inventions include special farming hats, wheelbarrows, and a weighted system to jumpstart seized engines that looks like a booby trap straight out of an old Looney Tunes cartoon.

Hu Songwen, a man from a small rural town in Eastern China, has suffered from kidney disease for over 20 years. Unable to afford the expensive, thrice-weekly treatments, Hu decided to tinker together his own blood-filtering machine in his bathroom. Yes. He pumps his own blood through a homemade machine in his bathroom.

With absolutely no formal medical or mechanical training -- he was studying meteorology before renal failure derailed him in 1993 -- Hu whipped up a working dialysis setup that's kept him alive like some kind of DIY Darth Vader ever since. Now, each treatment costs only 12 percent of what it would in a clinical setting. Even more impressively, Hu hacked together his life-preserving doohickey using only a medical textbook, kitchen equipment, and good old fashioned technical ingenuity. You know what they say: fear of imminent death is the mother of invention.

Hu wanted to stress that he didn't consider himself a genius or a hero for doing this and that nobody should ever copy him -- he resorted to medical-grade techno-riffing only because he couldn't afford to do it the right way. Thanks to new state insurance regulations, Hu has become eligible for affordable treatments at an actual, bona fide hospital. But he's not sure if that's going to work out -- the hospital is too far and too crowded to use reliably for those thrice-weekly appointments.

China censors their Internet, and homeless farm-workers in Brazil probably don't get it in the first place. But maybe we can get the radio kid to build some sort of rudimentary cyberspace out of cans and kitchen appliances, so Hu and the homeless car guy can hook up and exchange blueprints. The Shrimpmobile is awesome, but one fender bender and its driver might suddenly find use for a dialysis machine.
