For the 7th year of dorkbot SF, Greg Leyh hosts a meeting at his Lightning Lab which closes its doors in San Francisco at the end of the month (June) and moves to the East Bay.

He talks about the various research possibilities for the proposed lightning lab which will be built in Nevada. They are 2 12 story Tesla coils which can produce football-field sized arcs. There will be a visitor center. At the end of his presentation, Greg demonstrated some Tesla-roasting technique on some corn using an 11 ft Tesla coil. Videos of the Tesla Coil demonstration on the anniversary archive page here.

Video taken by dorkbot regular James Young. Q&A portions starts at about 20 minutes in. The demo followed.

Vodpod videos no longer available.

Other speakers that evening were Marc Powell on his Food Genome software and Jonathan Foote on his light printer Ghostmatrix.

Yes, dorkbotSF has been around for 7 years in June! To commemorate, we’re having two events in June.

The first one will be on June 3 at Greg Leyh’s Nevada Lightning Lab where he’ll discuss possible research at NLL and do a live testing of various loads on his 1/12th scale of the 2 12-story tesla coils he’s planning to build. Food Hacker Marc Powell is going to show off his latest Food Genome project and bringing some dope food for us all! And the ever prolific Jonathan Foote will be showing us a light printer he calls the Ghost Matrix scavenged from different parts including scrap from SRL! Kevin Ottalini will also show his Marx Generator and the NLL in Half-Life!

More details on the dorkbotSF 7 Year Anniversary MEETING here (Jun 3).

Then about a week and a half later, Jon Sarriugarte is hosting a dorkbot party meeting to end all party meetings at his Boiler Bar in Oakland! Many surprise speakers and strange electrical gizmos to demo so you really have to go as not all of them will be announced! But on the lineup he’s got Omega Recoil’s twin Tesla Coils that will be running live, the Golden Mean, Marriage Wrecker and Muffin Art Cars! Greg Solberg and Keith Johnson teaching how to build an electric car from scratch (Tesla roadster, muffin cars, marriage wrecker), Jon is giving the audience a choice of several topics he could present so YOU choose: Giant Iron Snail Car, Golden Mean, 1928 Hogan Tesla Coil, Power Tool Drag Racing, Volt-Aged Whiskey and Mike Winter will show his artificial personality projects and interrogation by robots!

There’ll be food and beer, fire gardens, and live electrocutions with the 1928 Hogan Device!

More information on the dorkbotSF 7 Year Anniversary PARTY here! (Jun 20)

So hopefully you all can come out to one or preferably both events and celebrate 7 years of people doing strange things with electricity in the Bay Area!

Stills from Electric Earthquake animation

Electric Earthquake!

I was fussing around on the Internet Archive today (a nice cloudy day Saturday activity) and came across some great old videos. Old insanely sexist coffee commercials and surreal advertisements with cigarettes doing square dances. Totally wierd. One of the most fascinating, however, was an old superman cartoon. Basic story according to the Archive: A mad scientist attempts to blow up Manhattan. Lois Lane investigates and Superman saves the day. It’s nine minutes long and totally worth watching.

A couple interesting points…
– My favorite quote: “Maybe modern science will make you think differently!” This cartoon was produced in 1942. This is the year America landed in Europe and it is also the dawn of the Manhattan Project. Mad science is in the popular imagination: is science out of our control? In 1942, Kurt Vonnegut published “Player Piano”, a dystopian view of a world run by machines. Isaac Asimov also published the 3 Laws of Robotics in the story “Runaround,” as well as the first Foundation story. Robert Heinlein published the story “Waldo”, which dealt with the dangers of not thoroughly testing new technologies (and included broadcast power, radioactivity, and massive remote controlled machinery) . Who can save us? Superman!

– The mad scientist is Native American and is threatening to blow up Manhattan unless it is “vacated.” An interesting bit of xenophobia. Native Americans aren’t generally portrayed as loner mad scientists. Is this transference of some sort from other dark skinned peoples? The Japanese? Jews?

– Oh, the wonderful machines! Massive sparks and dials and cables. The lab is located underwater and there is a special elevator to get down into it. The scientist’s master machine is huge and has a tesla coil with dials and tubes! It may have been inspired by the Tesla Oscillator (also called The Earthquake Machine), though that was a thoroughly mechanical device. There are certainly enough high voltage sparks to invoke Tesla. Hooray, Modern Science!

– One of the most striking things about this bit of animation is the styling. It is gorgeous. All hand painted, of course, and full of beautiful color gradients and wisps of fog and water lapping. It really made me think about what we lost in the rise of flat animation during the 70s and 80s and in later computer generated imagery. Animation may be cheaper to create now, but I would love to have one of the cells from this.

So, a lot of thoughts from a little nine minute clip.
