Guess who made the lede for Forbes’ coverage of Toorcamp!
I certainly wouldn’t want to mess with this gang. Particularly after an annoyingly long photoshoot session…
The Tesla Gun was chosen to be the opening project of the 2012 Popular Mechanics DIY Backyard Genius awards! PopMech
hasn’t updated the website yet, but it’s already out in print (September 2012). In the meantime, here’s photographer Kyle Johnson’s photo blog.
UPDATE: Here’s the link on popmech.com.
They Rectify! Amplify! Generate! Control! And Transform Light to Electricity and Back Again! They’re Winning The War!
I’m going to try to merge my (private) project wiki with the public blog. This calls for a new spark-o-licious theme! Pardon the dust while stuff gets added and shuffled around.
The background shot is one of my early attempts to design a modulated flyback driver. Sparks emerge from a tungsten electrode (at the top), striking a piece of highly ordered pyrolytic graphite (at the bottom). The original photo and others from those days are up on Flickr. The coil resonated at around 20 kHz, but the driver was horribly inefficient, requiring heat sinks and turbine fans. I’m having much better luck with the ZVS driver these days.
Well, I’ll tell you what I paid for them. I traded a shrunken Susan B. Anthony dollar for a 10-byte note, and a shrunken quarter for a 5-byte note. That puts the direct exchange rate at about 10:1 (B:$). We agreed that since they were shrunken coins, it established a fair “proof of work”.
But it gets more complicated than that. The going eBay rate for a shrunken dollar is about $21 for a $1 Sacagawea. That puts the exchange rate at roughly 1:2 (B:shrunken $).
Money is complicated.
I think I’ll hang my bytecoins on the wall and watch them appreciate… That seems like the fiducially responsible thing to do.
Also: Happy 99th Birthday, Alan Turing!
I just got a new set of Moo cards, and boy are they sexy. Now with 106% more AWESOME!
