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.

Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]
Amélie Lamont, a former staffer at website-hosting startup Squarespace, writes that she often found herself disregarded and disrespected by her colleagues. One comment in particular, though, set her reeling — and came to exemplify her experiences there.

Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
