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.

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."

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.
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.

Aaron sez, "An engineer gutted an old Volkswagen that he bought on Craigslist and designed a custom electric motor for it. It can hit 82 MPH!"
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.

High voltage hackers ArcAttack of Austin, Texas, are known to BB readers for their Singing Tesla Coils that they use to perform music. For example, here, a pair of coils delight us with an, er, energized rendition of the Doctor Who theme. Sadly, it's unlikely that most of us will get a chance to try our hand at conducting this Tesla orchestra so ArcAttack has enhanced their Web site with a simple yet fantastically fun Tesla Coil Emulator. My first number was the familiar tune from Close Encounters of the Third Kind. What song would you like to hear the coils sing? From the ArcAttack site:

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.
Seen in the video above is Anaconda, a new system for harvesting energy from the ocean's waves. The 8-meter long, water-filled rubber "snake" is a prototype of a 200 meter version that the developers, Atkins Global, hopes will generate the energy required to power 1000 homes. The device is currently under testing in Gosport, UK and Checkmate Seaenergy hopes to bring it to market by 2014. I was surprised to learn that one of the big challenges to harvesting tidal wave energy is that the mechanical devices don't tend to last long because they get so abused by the ocean.

(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.
Although I won't sacrifice my own microwave to replicate this experiment showing the surprising effects of nuking a mobile phone, I'm glad that one of the web's many amateur scientists did so and recorded the outcome.
