Nikola Tesla is one of the most tragic figures in the history of science, a history that is practically filled to the brim with tragic figures. Francis Bacon, a 16th century philosopher and scientist, caught pneumonia and died because he was trying to stuff snow into a dead ch ...more

Time to prepare for that upcoming insufferable summer heat. For real. This tutorial actually works. Instead of freon, you will be using cold water from an ice bucket to run through copper tubing. As Rube Goldberg as this appears, this very principle of cooling is employed, ...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

Personally, I know life would be a lot easier if the people in it could just read my mind. Since that technology is currently unavailable, it's comforting to know that your air conditioner can be your personal telepathist with Sensibo. Sensibo works with any A/C unit that has ...more

If a solar-powered air conditioner that requires no electricity or moving parts sounds to good to be true, well, then you're not as ambitious as this clever high school student. Instructables user Fozzy13 put together an awesome DIY tutorial on how he built his own air conditi ...more

It's hot this summer, but it's not that easy to cool down when you're on the go. You can't take an air conditioner with you, and a handheld fan will just tire you out, so you'll need to find more creative ways to cool down when you're on the go. One of these ways is a DIY sola ...more

With the microwave oven transformer (M.O.T.) salvaged in a previous project, a simple electrical circuit can be rigged to get high voltage arcs to fly outward and upward along a "V" shaped spark gap. You can look, but don't touch! These arcs of plasma are lethal enough to kil ...more

While other devices are moving away from fingerprint scanners (cough, iPhone X), for many, a fingerprint scanner provides the best balance between security and speed. Typically, the rear fingerprint scanner on the LG V30 is quick and accurate, but every so often the phone will ...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

Silence spreads over these mountains like nothing I've ever felt. If I didn't have Moby blasting in my earphones, there'd probably be no other sounds around. Well, except for someone, Phil probably, murmuring in a nearby tent just low enough to make his words indiscernible. W ...more

Welcome back, my hacker novitiates! Now, and more so in the future, wars will be fought hacker v. hacker. The number of soldiers, guns, tanks, and ships will be less important in your success in warfare than the number of well-trained hackers you have. Every nation and every ...more

Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity ...more

Google's Tilt Brush has proven to be one of the most compelling VR experiences for the HTC Vive, letting you paint with crazy materials like electricity and duct tape. It is clearly an experiment in bringing the joy of imagination to life—or creating some form of virtual LSD—a ...more

When temperatures drop and hit new lows during the cold, winter months, it's hard not to crank the heat up. That means increased energy bills each month, no matter if you rely on gas, electric, or another fuel for heating. Instead of resorting to blankets, coats, and layers u ...more

Food waste is a topic near and dear to my heart, but the truth is, no matter how dutiful we are about finding ways to double-down on food scraps, a lot of stuff goes into the trash needlessly. Composting is the obvious answer. This is the process of taking organic waste (thin ...more

I don't know how many of you had this experience in your youth, but when I was a kid, I used to actively think about what would happen if I suddenly woke up in a fantasy land, or were to pass through a portal into another space and time. I knew it wouldn't really happen, but w ...more
