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.

A really bad new law in Australia gives police the right to force companies like Apple to ‘backdoor’, or create encryption circumvention alternatives, in all their products. The issue has been controversial in the U.S. for a long time, and spiked in 2016 after the mass shooting in San Bernardino.
“A single suicide by an Uber investigator who posts that they could not ‘take’ the job demands any longer will be fodder for the national if not international news media,” the memo said.
“A new Twitter is coming,” tweeted Twitter today. “Some of you got an opt-in to try it now. Check out the emoji button, quick keyboard shortcuts, upgraded trends, advanced search, and more. Let us know your thoughts!”

These days, there isn’t much our iPhone camera can’t do – except feel like an actual phone. Despite years of steadily increasing resolution and image sensing technology, we’re still taking shots awkwardly with two hands, fumbling for the shutter button. Leave it to an avid photographer to design Shuttercase, a versatile iPhone case that solves […]
