This Scratch-Built X-Ray Tube Really Shines

On no planet is making your own X-ray tube a good idea. But that doesn’t mean we’re not going to talk about it, because it’s pretty darn cool. And when we say making an X-ray tube…

Multi-Stage Ion Thruster Holds Exciting Promise

Anyone who’s looked into high-voltage experiments is likely familiar with ion lifters — spindly contraptions made of wire and aluminum foil that are able to float above the workbench on…

Sputtering Daguerreotypes, Batman!

The Daguerreotype was among the earliest photographic processes, long before glass plates or film, that relied on sensitizing a thin layer of silver on top of a copper plate. The earliest Daguerreo…

Junkbox Build Keeps Tesla Coils Perfectly Varnished

Admittedly, not a lot of people have a regular need to varnish coils. It’s mainly something that Tesla coil builders and other high-voltage experimenters are concerned with. But since that gr…

Atmospheric High-Voltage Motor Makes Useful Power

While it almost seems like an insane fever dream from an otherwise brilliant inventor, Nikola Tesla’s plan to harvest energy straight out of the atmosphere and essentially give it away is mor…

ESP32 Powers Fresh Take On An IoT Geiger Counter

Over the years we’ve covered many projects aimed at detecting elevated radiation levels, and a fair number of them have been Internet connected in some way. But as they are often built around…

A Home Made Laser Cutter For 700$

While some decent lasers are out there for under USD 400, they tend to be a little small. What if you wanted something a little nicer but didn’t want to jump to the USD 2000 category? The ans…

Scrambling Pocket Calculators Made Easy With EMP Box V2

[Rostislav Persion] has for some time been interested in making small, portable EMP devices capable of interfering with nearby electronics. In these EMP devices, high voltage is used to create a po…

ElectriPop Turns Cut Mylar Into Custom 3D Structures

Mylar has a lot of useful properties, and as such as see it pop up pretty often, not just in DIY projects but in our day-to-day lives. But until today, we’ve never seen a piece of Mylar jump …

The Most Deadly Project On The Internet?

A Super Simple DIY Ozone Generator

[Advanced Tinkering] needed a source of fresh ozone for some future chemistry related projects, and since buying an off-the-shelf unit would be, well, just plain boring, it was obvious what to do (…

High Tech Pancake Tesla Coil Brings The Lightning

For several years now we’ve been following [Jay Bowles] as he brings high-voltage down to Earth on his Plasma Channel YouTube channel. From spark gaps made of bits of copper pipe to automotiv…

Spark Plug And Plumbing Parts Bring Nitrogen Laser Under Control

When it comes to high-speed, high-voltage switching, there are a wealth of components to choose from — MOSFETS, thyristors, IGBTs, and even vacuum tubes like thyratrons. But who needs all tha…

Remoticon 2021 // Jay Bowles Dips Into The Plasmaverse

Every hacker out there is familiar with the zaps and sizzles of the Tesla coil, or the crash and thunder of lighting strikes on our hallowed Earth. These phenomena all involve the physics of plasma…

Glitch Your Way To Reverse-Engineering Glory With The PicoEMP

Most of our projects are, to some extent, an exercise in glitch-reduction. Whether they’re self-inflicted software or hardware mistakes, or even if the glitches in question come from sources …
