Electric Volt

Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and volta ...more

A deck of cards may be a magician's best way to demonstrate his or her's sleight of hand, but for the prankster, it's the perfect way to deliver a shocking 300 volts of electricity! And that's exactly what I'm going to show you how to do today. Stuart Edge used it in his "Elec ...more

Want an electric car without the price tag? You could always build your own, or maybe just hack your old gas guzzler into an eco-friendly electric machine... This weekend at Defcon, security consultant David Brown showed off his "Voltswagon" project, a 1974 Beetle named Shocky ...more

Sputnik, Apollo and the Space Race. If you watched the State of the Union address last night, you probably heard President Barack Obama mention those three things. The Space Race was an informal bout between the Soviet Union (USSR) and the United States (USA) over the ascenda ...more

Wish you could make the shift to electric or hybrid, but you can't afford it? If you've got more than a few free weekends on your hands, you may want to consider undertaking Benjamin Nelson's ambitious (to say the very least) car conversion project. First, Nelson outlines in ...more

Around the world, X-People (yes... there are X-Women, too) are under attack from an intolerant sapiencentric ruling class. Integration without equality is a farce. Autonomy is denied outright. Human prejudice cannot abide a mutant state. Human fear, born to hate, imposes itsel ...more

Congrats to WonderHowTo Jackass 3D prank contest winner Grayson Robison! His winning idea: Connect Knoxville to a real life Operation game with shocking devices. Every time a player screws up and the buzzer goes off, the "patient" gets a burning shock to the correlating body ...more

Tesla coils are totally insane, yet undeniably captivating. And they can be used for many things, from electric painting to dueling musical battles. But one trigger happy fellow has a different use for Tesla's lightning shooting coil. A weapon. After being inspired by the ste ...more

Looking to be the world's best violinist or fastest banjo player? If you didn't start practicing when you were a kid, learning a new stringed instrument is extremely challenging. But an upcoming device may change all of that, if you don't mind being shocked by 28 different ele ...more

...his easy laugh and southern charm.  Pull this trigger...it is just so electric.  Not just the spark, but the 50,000 volts cursing through the tumid chamber, filled with liquid soluble polydimethalsiloxane. Okay. Okay.  Maybe it did not go exactly like that.  Maybe all the ...more

Chemical engineers at Cornell have created a small device that may one day turn troops into real life spider-men. The device would cradle in the palm of the hand, allowing troops to scale walls. It uses an adhesive inspired by the Floridian leaf beetle, an insect that "can adh ...more

As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the pri ...more

R/C car manufacturer Losi just recently released the LOSI 1/10 TEN-T TRUGGY RTR, which is apparently the world's most advanced radio controlled car. The Ten-T is 18 inches long and 6.2 pounds, and operates like a real race car (but at 1/10 of the size). Check out these specs ...more

I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guita ...more

Fans of Doctor Who know that the sonic screwdriver is the ultimate tool. It can unlock doors, turn on lights, detect life forms, solder wires, and sabotage weapons. Presumably, the sonic screwdriver creates sonic vibrations to achieve whatever the doctor wants by vibrating th ...more

I have an absolutely wonderful time making projects and writing articles for all of you mad scientists! Today, I will bring you behind the scenes for a look at the workbench, tools, and software that make the Mad Science World possible. Above is my beautiful workbench! My who ...more

Video: . I made this Tesla Coil using the myRIO and LabVIEW. It uses electricity to play the music, which can be Star Wars, Harry Potter or even Hunger Games! The music is played by the spark heating the surrounding air (causing it to expand) then the spark turning off (causin ...more

One of the roles our government has taken on is to provide us with information to be used in making decisions. For example, the EPA stickers on the Nissan Leaf and Chevy Volt state that these electric cars can travel 93 and 99 miles per equivalent gallon. Unfortunately, the ...more

Got a screw loose? Don't worry. We all do. This handy tutorial will keep any screw secured to any screwdriver. This method of magnetization uses a copper wire and a car battery. This is much more effective than simply rubbing a screwdriver with a magnet. It also holds the ma ...more

The unrestrained joy of How-To cleverness. This subversive video shows you how to transform that old CRT monitor into a 30,000 volt fence. I apologize. This screen grab gives away the understated punchline to this otherwise sober minded tutorial. Notwithstanding, this little ...more

Eating flowers is a time-honored culinary tradition, from nibbling on nasturtiums to grazing on candied violets. And why not? They look beautiful and lend a unique floral flavors to salads, desserts, and anything in between. Don't Miss: Weird Ingredient Wednesday—Zucchini Blo ...more

A lot of my hacks use salvaged parts from an old microwave, with the microwave oven transformer (MOT) being the most useful component. In this "Quick Clip," I'll be using a MOT again (a dual MOT stack) to make deadly flame-looking electricity jumping around midair. This scien ...more

It's September 1st, 1859, and the Earth looks more or less like something out of an apocalyptic movie or Sci-Fi novel. All communications have failed, it's so bright outside at midnight that people are getting up and making breakfast, and people all over the world are seeing a ...more

Every step in the evolution of computing brings an in-kind leap forward in user input technology. The personal computer had the mouse, touchscreens made smartphones mainstream consumer devices, and AR headsets like the HoloLens and the Magic Leap One have leveraged gesture rec ...more
