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.

Well, it’s finally official. After more than a year in regulatory limbo, The United States Justice Department has approved a $26 billion dollar deal between mobile carriers T-Mobile and Sprint.
Donald Trump says his administration will not provide any waivers or relief for Apple Mac Pro components built in China, and said Apple should instead build its products in the U.S.
We can expect three new “iPhone 11” models this fall from Apple, according to the official unofficial rumor mill. Each of these is said to be designed with an A13 chip, a Lightning port, and a new ‘Taptic Engine’ that will replace iPhone’s current 3D Touch.
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
Want to make a hit? The right software is out there for anyone, but any music producer will tell you that finding the right sound can still take time and talent. Still, the right tools are a great shortcut, which makes this Synth & Sound Pack Bundle absolutely priceless. And now that it’s on sale […]
