Awesome Electricity

The Plasma Piano

The Plasma Piano

After melting all of the strings on his piano with high-voltage sparks, Mattias Krantz wanted to see if he could still make music with the thing. So he got to work building a series of circuits that fire plasma arcs onto the piano’s metal backboard to make sounds when he presses the piano’s keys. But it wasn’t easy getting it to work.

Experimenting with Low Voltages and High Currents

Experimenting with Low Voltages and High Currents

Mehdi from ElectroBOOM demonstrates the relationship between voltage and amperage by reducing the output voltage of a microwave transformer to the point that it produces massive amounts of current. Expect lots of buzzing noises, noxious smoke, math equations, and melted objects along the way.

Avengers on Tesla Coils

Avengers on Tesla Coils

Marvel characters like Living Lightning, Electro, and Thor have the ability to control electricity. But only one of those guys is an Avenger, so we’re imagining that the tesla coils in Franzoli Electronics latest video are basically rounded versions of Mjölnir shooting their lightning bolts at Captain America’s Vibranium shield.

Making a True Bladeless Fan

Making a True Bladeless Fan

Those fancy Dyson fans are called “bladeless,” but they really just hide their fan blades in the base. Integza wanted to see if it would be possible to build a fan that actually has no blades. His theory was that he could harness and direct the ionic wind created by high-voltage electricity.

Capturing Electrical Arcs in Slow-Motion

Capturing Electrical Arcs in Slow-Motion

Mehdi Sadaghdar from ElectroBOOM has made a career out of playing with electricity. He teamed up with Gav and Dan of The Slow Mo Guys to shoot some high-voltage sparks from his tesla coil and Marx generator. They managed to capture some incredible shots at speeds up to 1,750,000 frames per second. Here’s Mehdi’s video.

Literal Electric Piano

Literal Electric Piano

Musician and maker Mattias Krantz has done some pretty crazy things to pianos. This time, he teamed up with Mehdi Sadaghdar of Electroboom to create the most dangerous piano ever. Using a bunch of cheap camera capacitors, he modified his hammer-head piano to create high-voltage sparks when played.

Around the World on Tesla Coils

Around the World on Tesla Coils

During their 28 years together, Daft Punk used lots of synthesizers and electronic equipment to make their music. But as far as we recall, tesla coils were not in their arsenal. Thankfully, we have Franzoli Electronics, who used his high-voltage noise-makers to play an awesome cover version of Around the World.

Syringe vs. Tesla Coil

Syringe vs. Tesla Coil

Tesla coils give us one of the few controlled ways to see electricity. Apparently, if you stick a nail into a plastic syringe, point it at a live tesla coil, and pull its plunger that it would extract the electric plasma into its barrel. Original footage from ElectroBOOM.

Why Do Electric Plugs Have Holes?

Why Do Electric Plugs Have Holes?

The reason that electric plugs typically have two or three metal prongs is very easy to explain. But what about those holes you see in the tips of the prongs? Silver Cymbal digs into the backstory and purpose of this mysterious design attribute and shines some light on the topic.

This Is Not a Perpetual Motion Machine

This Is Not a Perpetual Motion Machine

Drop a marble into the top of this tabletop sculpture, and it rolls down a ramp and back into itself endlessly. While it might appear to defy the laws of physics, the trick is that its base contains a hidden battery and electromagnet that accelerates the steel sphere as it comes down the ramp.

Building a Massive Portable Power Bank

Building a Massive Portable Power Bank

If you search around on Amazon, you can find some pretty big portable power banks. But Handy Geng needs more milliamp hours of power, so he got to building this enormous power pack that has batteries totaling 27,000,000 mAh (or 27,000 amp-hours) of power output. And yes, it’s still portable, kinda.

Fixing the Mythbusters’ Water Stun Gun

Fixing the Mythbusters’ Water Stun Gun

Allen Pan is a big Mythbusters fan – but he thinks they got one of their experiments wrong. In 2008 Adam, Jamie, and Grant attempted to create a stun gun that shoots electricity through water and failed. Allen came up with a different approach, playing with laminar flow to keep power flowing through two streams of water.

Making a Supercapacitor Electric Bike

Making a Supercapacitor Electric Bike

Supercapacitors have one big advantage over batteries – they charge much faster. But they also discharge energy more quickly, limiting operating range. This makes them suboptimal for EVs. Engineer Tom Stanton built a supercapacitor pack and drive unit for an E-bike to see just how it stacks up to battery power.

How Many Solar Panels Could Power the World?

How Many Solar Panels Could Power the World?

Solar energy is out there for the taking, but is it really free? Wren from Corridor Crew digs into the realities of generating power from various energy sources, and illustrates the number of solar panels and space we’d need to replace dangerous fossil fuels with clean solar energy.

1000-Amp Hot Knife

1000-Amp Hot Knife

It’s been a while since we checked in on PhotonicInduction’s dangerous and destructive electrical experiments. With 1000 amps running through the blade of a kitchen knife, it glows a brilliant reddish-orange and can surely slice through much more than a stick of butter. But how long until the knife itself fails?

Cooking Hot Dogs with Capacitors

Cooking Hot Dogs with Capacitors

Capacitors are capable of storing large amounts of energy and releasing it quickly. The Backyard Scientist teamed up with Peter Sripol and William Osman to show just how dangerous capacitors can be by subjecting a variety of objects to the power stored in a 20,000-volt bank of capacitors. Don’t even think of trying this at home.
