Maker Peter Sripol wanted to see if he could build a functional submarine using off-the-shelf parts and a $100 budget. He assembled its frame from PVC pipe and 3D-printed connectors, and its remote steering mechanism is completely analog. He even rigged it up to pick up undersea “treasure” with magnets.
Awesome Peter Sripol
A paramotor is a single-person flying machine with a parachute wing to keep it aloft and a large fan to propel it. Aviation buff Peter Sripol wanted to see if it was possible to create a version powered by a bunch of individual drone motors instead, and as you can see from the thumbnail, he succeeded. It’s insanely loud though.
Most airplanes do just fine with one to four engines. But that didn’t stop the guys at FliteTest, their pal Peter Sripol, and a team of volunteers from building a remote-controlled plane with 25 engines on each of its wings. The massive foam and cardboard plane has a wingspan of 30 feet. We’re amazed it could lift its own weight.
Lots of people celebrate the 4th of July with fireworks, but maker Peter Sripol won’t settle for those cheap little fireworks you can buy at the store. After making a gigantic spinning firework last year, he built a super-size version of one of those unpredictable rocket-style fireworks.
It’s pretty easy to find toy airplanes that are powered by a rubber band. On the other hand coming up with something that replicates the dual rotor movements of a helicopter is more of a challenge. Maker Peter Sripol managed to create one. Download the 3D printed part designs on Thingiverse and watch the build video here.
Airplane enthusiast Peter Sripol’s followers gave him a challenge: Could he build an airplane that’s entirely propelled by PC cooling fans? After testing a few different fans and configurations, he came up with a lightweight design he was satisfied with. We wonder if it could be scaled up with more fans and batteries.
NERF guns often use electric motors to launch projectiles quickly. But an off-the-shelf NERF Elite 2.0 Turbine CS-18 wasn’t badass enough for builder Peter Sripol, so he replaced the stock drive mechanism with a Toyan 4-stroke gas engine, typically used to power high-end RC vehicles. It’s not dramatically more effective, but it is noisy.
Builder Peter Sripol revisits a project he’s been obsessed with for years. The latest version of his homebrew ultralight flyer incorporates wings made from custom-cut foam, vinyl, and aluminum pipe. We love the whirring sound its motor makes when it takes to the air. You can catch part one of the build here.
Electric bicycles are a fast and fun way to get around. However, they have limited range due to their small battery packs. Peter Sripol wanted to see if he could build an eBike that never needs recharging as long as the sun is shining. The downside? The trailer of solar panels he has to drag along. Build starts at 2:20.
Independence Day is nearly upon us, so it’s time to amp up the fireworks beyond the nightly booms of cherry bombs and M80s to something a little more spectacular. Maker Peter Sripol decided to see if he and his pal Sam could build oversize versions of two kinds of spinning fireworks displays, each powered by model rocket motors.
Back in the 1960s through the 1980s, the Soviet Union developed a low-flying aircraft that could skim like a hovercraft over the water. R/C flying enthusiast Peter Sripol decided to see if he could build a working miniature replica of the so-called “Caspian Sea Monster,” and attempted to keep it flying just inches off the ground and water.
After a earlier and not very successful attempt, maker Peter Sripol and his friends managed to build a lightweight, remote-controlled airplane that gets its propulsion entirely from an off-the-shelf leaf blower. By improving upon the materials and aerodynamics, this version fared better in the air… eventually.
You know those fireworks that look like a tiny tank? Well builder Peter Sripol decided to celebrate the 4th of July (and 1 million subscribers) by building himself a gigantic replica of the thing. Naturally, his version makes a lot more fire. Plus, it was reusable – at least for a while.
Maker Peter Sripol plans on participating in DroneClash – a sort of BattleBots for drones. In this clip, he shows off the design and work that went into his ultra-sturdy machine that looks more like flying pizza box than a drone, but should do a great job fending off enemies.
After building himself an airplane, Peter Sripol decided to make himself something a little less ambitious, but just as fun – a tricked-out sled that can glide across the snow thanks to an airplane propeller on the back. It’s not exactly fast, but it lets him go sledding without a hill.
