Several years ago, I wrote a MAKE: article about Greg Leyh, a brilliant, understated high-voltage engineer/artist in San Francisco who builds the world's largest Tesla coils. For as long as I've known Greg, his dream has been to create a massive lightning laboratory with two 10-story Tesla Coil towers to study high-power scientific phenomena. Indeed, Greg's operation is called Lightning On Demand. With the only barrier being money, Greg has now come up with a "highly cost-optimized version" of the Lightning Laboratory. With this new design, Greg only needs $348,000 to make it happen. And he's launched a Kickstarter project to seek funding to build this magnificent DIY scientific instrument. Greg says:
Rather than being a purpose-built, conservatively designed machine, the new approach is literally designed around used materials, scrap and salvaged equipment. There’s a lot of great obtainium out there these days!
This new design should still be able to produce the conditions needed to trigger a relativistic avalanche as per Gurevich and Zybin’s calculations [200kV/m, 50m characteristic avalanche length.] Ultimately I hope to trigger a super-long discharge event and discover if there’s any connection with Gurevich’s relativistic runaway breakdown theory, or at least get some gamma-ray precursors.

The Cobham catalog, exposed by The Intercept, features countless pages of surveillance gadgets sold to U.S. police to spy on American citizens: tiny black boxes with a big interest in you. In the creepily bland feature lists and nerdy product names is a whisper of a dark future; perhaps darker than anyone can imagine.
This image depicts the most commonly-found stylesheet colors on the web’s top sites—Paul Hebert did an amazing amount of analysis and this is just one of the intriguing visualizations he came up with. Most of these are obvious staples, especially HTML red and blue, though it’s interesting how far the blue “cluster” is from the […]
With the cacophony of an election year ablaze with unparalleled drama being fought on the front lines of Twitter, we find ourselves slowing down and staring at it like a bad accident.

These headphones are foldable so they’re easy to carry around, but most importantly, they pack impressive sound. Our biggest struggle with Bluetooth headphones is the worry of them dying at the worst moment. This pair lasts an impressive 8-10 […]
