AC vs. DC

AC vs. DC

“You know what they say about AC? It Hertz!” Want to learn the differences between alternating current and direct current? Mehdi from ElectroBOOM is here to lay down the law on the not so subtle ways that these two types of electricity vary. Caution: Science Ahead.

The Boy Who Cried “Free Energy”

The Boy Who Cried “Free Energy”

Mehdi Sadaghdar puts on his superhero guise as “The Rectifier” to debunk another ridiculous claim of “free energy,” as he crushes the hopes and dreams of a young inventor who has been making the rounds with his supposed energy-harnessing machine.

State of Emergency Motherf**ker!

State of Emergency Motherf**ker!

(PG-13: Language) Mehdi just wants to know if his buddy got lucky. If only Samy would stop blabbing and get to the point. Then the day’s beatdown from the cops would be so mundane. We sincerely hope Sébastien Petretti’s comedy short film remains a hyperbole.

Fake DIY Projects Exposed

Fake DIY Projects Exposed

ElectroBOOM’s Mehdi Sadaghdar is mad as hell, and he’s not going to take it anymore. After seeing way too many videos of fake science and “lifehacks,” he decided to do something about it, and debunked a few of the more heinous ones.

On “Free Energy” Devices

On “Free Energy” Devices

ElectroBOOM’s Mehdi Sadaghdar expresses his disdain for “perpetual motion” devices which are claimed to produce more energy than is put into them, thus defying the basic laws of physics. The only thing these guys seem to be able to actually generate are YouTube views.

Trying to Make a Vacuum Chamber

Trying to Make a Vacuum Chamber

ElectroBOOM needed a vacuum chamber to see if his Tesla coil will still make sparks in a vacuum. But instead of buying one or looking up guides, he decided to wing it. “Sometimes spending money saves you more money and time.” We coulda told you that, Mehdi.

ElectroBOOM: The Battery Man

ElectroBOOM: The Battery Man

ElectroBOOM’s Mehdi Sadaghdar debunks the outlandish claims of Biba Struja, aka “The Battery Man,” who says he’s not only impervious to electric shocks (which Mehdi knows all about,) but that his body actually generates a meaningful amount of power.

Fake and Real Wireless Power

Fake and Real Wireless Power

Mehdi Sadaghdar takes on a fake life hack that’s gotten roughly 48 million views because it supposedly shows how to make a wireless smartphone charger that works from up to 50 feet away. He contemplates giving in to fakery, but ends up turning into the hero we need.

The Science Behind Railguns

The Science Behind Railguns

Mehdi Sadaghdar tries to make a railgun on a much smaller scale. He ends up making a music video, discovering Donald Trump’s origin story and of course hurting himself in the process. Learn more on his blog.

How 3D Printing Works

How 3D Printing Works

Leave it to Mehdi Sadaghdar to come up with an entertaining introduction to 3D printing. Watch as he risks life and limb to make a tree using a glue gun, as well as exploding rockets using a dedicated 3D printer. More on his blog. All we are is 3D printeeeers

Thermal Imaging’s Applications

Thermal Imaging’s Applications

Mehdi Sadaghdar uses the Seek Thermal infrared camera to explain the basics of thermal imaging, and why such consumer-grade versions are still useful even though they’re vastly inferior to professional equipment.

The Lipstick Robot

The Lipstick Robot

After nearly cutting off a limb with her chopping robot, engineer Simone Giertz built another somewhat askew robotic assistant, though this one is much more likely to make her die from embarrassment than blood loss. We think she should marry Mehdi Sadaghdar.

DIY Hand-powered Charger

DIY Hand-powered Charger

Mehdi Sadaghdar thinks power banks are stupid, simply another thing that needs to be charged. So he added a USB charging port to a crank-powered flashlight, but not before sacrificing a couple of gadgets.

How to Repair a Flat Tire

How to Repair a Flat Tire

Perhaps sick of subjecting himself to electroshock therapy, engineer Mehdi Sadaghdar decides to go for a drive. Unfortunately, his car has a flat tire, so he tries his hand at automotive repair. We’re thinking it’s time to call AAA.

Jump-starting a Car with AA Batteries

Jump-starting a Car with AA Batteries

Comic engineer Mehdi Sadaghdar tests if he can jump-start a car using only a dozen AA batteries. Yes, his car’s battery was actually dead and yes, he’s going to intentionally do something stupid so you won’t.

The Slayer Exciter Circuit

The Slayer Exciter Circuit

Bumbling engineer Mehdi Sadaghdar was skeptical of a simple circuit that supposedly results in a voltage high enough to power a light bulb wirelessly. So he tried to debunk it. Naturally, he ends up getting hurt. Emotionally.

How to Remove Your Mustache

How to Remove Your Mustache

…that’s right, “remove.” Mehdi Sadaghdar took some time off from explaining electronics basics to try out ways of removing his mustache other than simply shaving it with a razor. Respect to those who wax. Seriously.

How to Make a Taser

How to Make a Taser

“It’s a strange pain. It’s as if something’s stabbing your finger, but the blade – it doesn’t stop there.” The smart but forgetful engineer Mehdi Sadaghdar takes us through the steps and missteps of creating an electroshock weapon.

Blue Sky Painters

Blue Sky Painters

Established by Mehdi Ghadyanloo and backed by the government of Tehran, Blue Sky Painters turns drab buliding facades in Iran’s capital into murals with eye-catching illusions or drawings that interact with their surroundings.

How to Change a Light Bulb

How to Change a Light Bulb

The bumbling engineer Mehdi Sadaghdar takes on his simplest topic yet. This time he shows us the do’s and don’ts of changing a light bulb. Mostly the don’ts. Keep that in mind if you want to use this as a guide.

The Pain of Electricity

The Pain of Electricity

Our favorite engineer Mehdi Sadaghdar is back, and he’s as careless as ever. This time he sets out to answer which type of electricity is more painful – alternating current or direct current.

Vacuum Experiment Fail

Vacuum Experiment Fail

(LOUD) A couple of “scientists” try an experiment involving a vacuum pump and a rubber glove – when the unexpected happens. Maybe they got their lab safety lessons from Mehdi Sadaghdar.

Try and Make Your Own Coil Gun

Try and Make Your Own Coil Gun

Bumbling engineer Mehdi Sadaghdar is back with another educational and dangerous episode. This time he shows us how coil guns work, and does more things you shouldn’t do when making one.

Electrostatic Discharge 101

Electrostatic Discharge 101

While this topic may seem better suited to our other site, YouTuber Mehdi Sadaghdar’s “do as I say, not as I do” approach in talking about electrostatic discharge makes it right at home on The Awesomer.
