What better use for a pair of musical Tesla coils than FONentertainment's rousing 2010 chorous of "Dueling Banjos?"
MIT student Tyler Christensen created a musical Tesla coil hat for his Hallowe'en costume (it played the Mortal Kombat theme and the Harry Potter theme while discharging semi-tame lightning). While freely stipulating that this is "a really bad idea," Tyler is still generous enough to document his project for others who might follow in his bad footsteps.
Really, it’s just a DRSSTC. Nothing less, nothing more, nothing fancy. It was a bit tricky to make a bridge appropriately sized, and even harder to make a boost converter for it. In fact, the boost never truly worked. If I play a mid to high note for a few seconds, the boost can’t keep up and it fades away. I think this is due to saturation of my boost core, but I haven’t really taken the time to do much on this since now I’m back in the gate driver world and also have to throw together my 6.131 power electronics final project. I’ll fix hatcoil in February.
I love this video of my friend Lloyd Kahn (founder of Shelter Publications) talking about his joy of skateboarding. He's 76, and started boarding as a wee lad of 65.

Toby Morse, singer for the NYC Hardcore band H20 has spent the better part of the last year or so building up his One Life One Chance project. Inspired by the creativity and positivity he experienced in the punk / hardcore scene over so many years, Toby decided to create a vehicle to share that message with school age children across the country. Adopting the Bad Brains' PMA (positive mental attitude) as his slogan, he spoke at schools and spread the word in 2010, and plans to do the same and more in 2011.
His message is largely his own story about being straight edge and being in the band H2O. While he does talk about the upside of sober living, the bigger point seems to be the power of positive thinking and accepting people even when they are different than you. I think this is such a better approach than the old "Just Say No" or DARE campaigns. If you work at or with a school, check this out and consider having him come speak to your kids! Read the rest
Video link. This footage prepared for the North American Unicycling Championships and Convention contains some pretty unbelievable footage, including jumping over a picnic table, up a flight of 7 stairs in one hop, and the you-gotta-see-it-to believe-it "maxwhip." Also some amazing Kris Holm vids here and here. Read the rest
James sez, "I just completed a working build of Donald Michie's MENACE (Matchbox Educable Noughts And Crosses Engine), an early (1960) example of machine learning. MENACE uses 304 matchboxes to play Noughts and Crosses (or Tic Tac Toe in the US) - and learns over time to play it better. I built it for a talk at the UK games conference Playful, about Awesomeness and Miracles, particularly focussing on the work of Charles Babbage - and culminating in a surprisingly large version for playing Go..."
MENACE is a machine that plays noughts and crosses, built out of 304 matchboxes. Each matchbox corresponds to one of the 304 board layouts that the opening player might face (there are actually 19,683 possible board layouts, but we only need to calculate the opening player's first four moves, and many are rotationally or reflectively identical). In turn, each matchbox contains a number of glass beads corresponding to each possible next move. When it is MENACE's turn to play, the operator simply selects the matchbox corresponding to the current state of play, shakes it, and opens it to see which move has been chosen. Each matchbox contains a small nook into which one bead falls--and MENACE plays in the square corresponding to that bead.Read the rest
But what's really clever is that MENACE learns. Every time it wins a game, an additional bead is added to each matchbox played, corresponding to each winning move. Likewise, every time it loses, a bead corresponding to each losing move is removed.
BB pal and periodic guestblogger Richard Metzger has an amazing blog post up about the off-Broadway musical Man on the Moon. The play was conceived by John Phillips of the Mamas and the Papas and his third wife, South African actress, Genevieve Waite, as a potential film or stage production originally entitled "Space."
The stage performance was produced by Andy Warhol. Long-lost video footage of the play is embedded above. More video over at Metzger's blog, too, amazing stuff.
The following text was written by Chris Campion and Jeffrey A. Greenberg from the liner notes of the CD release of Andy Warhol Presents Man on the Moon.
I'll post a snip here, but you have to read the whole thing to hear about the part Philips wrote for Elvis, and all the weird little factoids about Warhol's work, and allegations that George Lucas stole the idea for Star Wars from this offbeat project. Snip:
Space was born the day Neil Armstrong first set foot on the moon. Like millions of other people, John watched the 1969 moon landing on TV. He was living, at the time, on the Malibu property rented by British film director Michael Sarne, who was under contract at Fox to direct the adaptation of Gore Vidal's novel, Myra Breckenridge, with Rex Harrison, Raquel Welch and Mae West. Sarne had commissioned John to write songs for the film.
The Apollo 11 moon landing became an obsession. John would watch a recording of the TV transmission made on an early video tape machine over and over. Read the rest

CERN, the world's largest particle physics laboratory, birthplace of the World Wide Web and home of the famous Large Hadron Collider (LHC) has a great opportunity for you. We are about to kick-start the most complex scientific project ever conceived by mankind, and would like you to witness and record its unveiling, and help us spread the news.
We want you to start by showing us your communication and creative skills by producing an original short film or multimedia piece, incorporating material about ATLAS, the biggest experiment on the LHC. The best submissions will be posted on the ATLAS website and YouTube page with full credit to the author, and enter a competition for a paid internship at CERN or alternatively win a Adobe Production Suite package. The winner will be offered a trip to CERN in Geneva, Switzerland, and given exclusive access to scientists working on the project as well as all the equipment and expertise in CERN's audiovisual lab.
What we want from you is your unbridled creativity.
Tischer converted a '91 VW Passat with a blown engine. He found it on Craigslist for $1,800. The Passat is a bit big for a conversion, he says, but it's aerodynamic and attractive. That counts for a lot. "It's just a professional looking car with a beautiful interior, and something I enjoy having as a daily driver," he said.Tischer's EV project
ArcAttack employs a unique DJ set up of their own creation (an HVDJ set up) to generate an 'electrifying' audio visual performance. The HVDJ pumps music through a PA System while two specially designed DRSSTC's (Dual-Resonant Solid State Tesla Coils) act as separate synchronized instruments. These high tech machines produce an electrical arc similar to a continuous lightning bolt which put out a crisply distorted square wave sound reminiscent of the early days of synthesizers. The music consists of original highly dance-able electronic compositions that sometimes incorporates themes or dub of popular songs. Joe DiPrima and Oliver Greaves are the masterminds behind the design and construction of the Tesla Coils while the music is developed by John DiPrima and Tony Smith.Tesla Coil Emulator Previously: Tesla coils sing the Doctor Who theme Singing Tesla Coil: video - Boing Boing Photos of Australian Tesla coil enthusiasts - Boing Boing Cool Tesla coil photos - Boing Boing Nikola Tesla profiled by Mark Pilkington - Boing Boing BBtv: Omega Recoil: Electricity as Art - Boing Boing Read the rest
(As the Anaconda moves, it forms "bulge waves") similar to those that pass through the human circulatory system and can be felt as the pulse in the wrist and neck, says Rod Rainey of Atkins Global, co-inventor of the Anaconda. When each bulge wave reaches the end of the snake it keeps a turbine spinning to generate electricity. The snake is made from a rubber-based material similar to that used to make dracones – flexible containers that are filled with diesel or water and towed behind ships for quick and cheap transportation. Other than the turbine, Anaconda has no moving parts and unlike other wave power devices it needs only one tether to the ocean floor. That lowers construction costs and reduces the need for maintenance – an expensive undertaking in offshore settings where corrosion and accessibility are problems, explains Rainey."Sea 'snake' generates electricity with every wave" Previously:Garage researcher "burns" saltwater - Boing Boing Sustainable Energy Without the Hot Air: the Freakonomics of ...
