Is that little lighter in your pocket not doing a very good job getting the fire started? Check out the jumbo-sized 500,000 BTU lighter that BrainfooTV made. Since it’s more flamethrower than Bic lighter, we don’t recommend trying to light your cigarettes with it.
Automotive madman Jimmy Built managed to cram the drive unit from a Tesla Model S and the battery pack from a Chevy Volt into an old Honda Accord. The result is a crazy lightweight car that can do 0-to-60 in about 2.7 sec, and sounds like a remote-controlled toy doing it.
Simone Giertz and William Osman teamed up to do something stupid and silly. They took Simone’s goofy Citicar and turned it into a giant computer mouse. Driving and steering controls the cursor, while honking the horn is a click. It totally sucks, but that’s what we expected.
The Beyond the Press channel took a powerful Gardner Denver air compressor and connected it up to a simple rig they built for firing tennis balls. It isn’t particularly accurate, but we still wouldn’t want to be on the business end of this thing. Test firing starts at 4:15, but it gets better.
After turning a bathtub into a drone, The Real Life Guys decided to see if they could cram 15hp electric motor into a little kid’s car known as a BIG Bobbycar. The result is a ridiculously unsafe and unstable ride that zooms from 0 to 43 mph in about 3 seconds. Turn subtitles on.
Laser engravers use powerful laser beams to burn designs into wood and other materials. But when Make Anything’s flatbed engraver broke, he decided to take its laser head and turn it into a handheld writing instrument. It’s not the safest thing on Earth, but it is cool.
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.
Did you break the tip on your pencil again? You could go for one of those fancy mechanical pencils, or you could rig up a pencil sharpener like the one Giaco Whatever hacked together – using a 1000cc two-stroke engine to spin the sharpener up to speed.
Weapon maker Joerg Sprave is always up for a challenge. When the makers of the game War Robots asked him if he’d build a robot, he obliged them with the world’s deadliest vacuum cleaner – which carries and fires a Glock. Never yell at this robot for missing a spot!
Giaco Whatever has an extensive history of making dangerous items. So leave it to him to transform a normally safe kid’s NERF gun into a deadly weapon, thanks to the pressure generated liquid nitrogen expanding inside the gun at room temperature. Kablam at 22:16.
Make: author Caleb Kraft came across this nifty plaything by Mike’s Electric Stuff, which uses sensors and a cylindrical grid of LEDs that simulate falling snow or sand as it’s flipped end-over-end. Mike needs to turn this thing into a toy you can buy. He’d sell thousands.
Got a broken washing machine and some woodworking skills? Then check out Scrap Wood City’s clip in which he shows how to convert the metal tub from a washing machine into the body for a fretless acoustic contrabass. It’s only got two strings, but it still sounds cool.
A while back, The Backyard Scientist built a massive mousetrap and used it to smash things. He decided to take all of the energy stored up in that giant spring and use it to drive an axle. Unfortunately, it seems as if its power should be measured in mousepower, not horsepower.
YouTuber Roadie fabricated a nifty motorized skateboarding rig that allows its rider to glide efforlessly (if not exactly quickly) along railroad tracks. Needless to say, don’t try this idea at home unless you’re 100% certain the rails are abandoned like the ones shown here.
MadGyver shows off a fun little project – an Arduino-based glove which can detect gestures, and uses the inputs to control the speed of a strobe light, which when aimed a moving object makes it look like it controls the speed and direction of time. Build details on Instructables.
One of the more entertaining robotic groups we’ve heard was built by FT Mechatronics, whose electronic band consists of a variety of stepper motors, solenoids, hard drives, oscilloscopes, a robot xylophone, nixie tubes, and a tesla coil. Here, it plays Hello by OMFG.
