If you think shorting a transformer’s winding means big sparks and fried wires: think again. In this educational video, titled The Magnetic Bypass, [Sam Ben-Yaakov] flips this assumption. By cleverly …read more Continue reading Hacking Flux Paths: The Surprising Magnetic Bypass
When you see a ventriloquist like [Jeff Dunham], you probably expect to see him with a puppet. This time – spoilers ahead – you won’t. Besides his fame on stage, …read more Continue reading Jeff Dunham Finds A NOS 1958 Philco Predicta
[Editor’s note: This video disappeared, but there’s another version here at the moment. We’re leaving the links as-were in case they come back up soon.] The aptly named [LightingOnDemand] has …read more Continue reading Lorentz Cannon Fires Lightning
Officially, the term “taser” refers to a particular brand of projectile-firing electric stun gun. However, the word is also colloquially used to refer to just about any device intended for …read more Continue reading Taser Ring Is Scary Jewelry You Shouldn’t Build
What do scanning electron microscopes and satellites have in common? On the face of things, not much, but after seeing [Zachary Tong]’s latest video on liquid metal ion thrusters, we …read more Continue reading Liquid Metal Ion Thrusters Aren’t Easy
A common part used to create a high voltage is a CRT flyback transformer, having been a ubiquitous junk pile component. So many attempts to use them rely on brute …read more Continue reading Flyback, Done Right
Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via MSN/WSJ] While the first …read more Continue reading Electrostatic Motors are Making a Comeback
Whilst microwave plasmas are nothing new around here, we were curious to see what happens at 20x the power, and since YouTuber [Styropyro] had put out a new video, we …read more Continue reading ‘Upgrading’ a Microwave Oven To 20 kW
For serious high-voltage plasma, you need a serious transformer. [Jay Bowles] from Plasma Channel is taking his projects to the next level, so he built a beefy 6000:1 flyback transformer. …read more Continue reading Pushing the Plasma Limits With a Custom Flyback Transformer
Drive along nearly any major road in the United States and it won’t be long before you see evidence of the electrical grid. Whether it’s wooden poles strung along the …read more Continue reading A Field Guide to the North American Substation
