Next Wednesday and Thursday, (Feb 17-18), at the DNA Lounge (“A disorderly house injurious to the public welfare and morals”) (375 Eleventh St; SF) is BarBot 2010. Tickets are $10 advance, $15 day of show.
Come out and have iZac pour you a fuzzy navel, and the girliest drink in the house!
NC State industrial design grad student, Joe Harmon is building a car by hand. Not just any car. A sports car that can reach 240 MPH. Not just any 700 HP, 240 MPH sports car. A 700 HP, 240 MPH sports car made almost entirely of wood. The body? Wood. The dash? Wood. The seats? Well, they’re wicker. The wheels? Oh, they’re wood too. The suspension? Yes, it’s wood too.
Because he wants strength, but also a reduced weight (wood has a higher strength-to-weight ratio than steel or aluminum), he is creating the body out of custom made plywood that consists of layers of eighth inch wide cherry veneer strips that are then weaved together, and glued on top of a weaved birch veneer, a core of balsa wood, and then another woven layer of birch. The panels are then vacuumed formed into shape, using the same technique that’s used for carbon-fiber composites. All told, about 30 species of wood are used to make up the car.
According to the last update, which was about a year ago, the outer shell was complete, but the internal components such as the V8 Cadillac Northstar engine and six speed Corvette transmission were yet to be installed. However, the car has drawn industrial sponsors like Delta/Porter-Cable, and has been making the rounds at different car shows.
Thanks Dad!
I’ve been thinking more about solar plants recently. I like how these projects combine both form and function. I’ve been thinking about what I’d like in one of these, and how one would be made. First, the power being collected by the solar cells needs to go somewhere. It could just feed back into the device, which is exactly what happens with plants, but part of me likes the idea of having the sculpture(?) have a practical use as well. If I want practicality, then USB ports for charging an iPod or a phone that I don’t have would be nice. At least one port, but four would be more than plenty. I’m leaning towards the solar cells charging some li-ion or nicad battery coupled with something like a Minty Boost.
The second feature I’ve been hammering the previous electronic plants I’ve looked at is the movement, specifically heliotropism (i.e. sun tracking). It’s an interesting feature, and it would increase the power to the photovoltaics. I don’t like the idea of the hearing servos move, so that means nitinol wires, which also have the quality of more closely resembling natural motion by simply expanding and contracting. The next question then becomes, what form would the motion would take?
If rigid photovoltaics are used, then panel could be mounted to a universal joint with the two outside corners independently controlled by nitinol. The other idea is to use flexible photovoltaics and hopefully no hinges and joints.
Another interesting idea is to think about deployable structures, which would seem to imply the use of flexible photovoltaics. It’s not exactly the heliotropism I was thinking of, but it would be cool if the “leaves” opened up in the day, tracked the light, and then closed at night.
Doing all of this nitinol might be kind of difficult. Heating nitinol causes it to contract in the 3 – 5 % range, doesn’t seem like much. This also means that for a deployable structure, it needs to collapse when the wires are extended,
Will I actually build this? Probably not, but it is something I’ve been thinking about. Perhaps it would give me an excuse to visit Noisebridge.
Taking a commission from Seoul’s City Gallery Project, The Living created Living Light, a vaguely forest-like structure that features a map of Seoul across the canopy. Each of the 27 panels in the canopy represents a particular neighborhood in the city. At night, each panel is illuminated based on air quality data as measured by various sensors throughout the city. Every 15 minutes, the panels turn on in the order of best quality to the worst.
Make highlights Phil Clandillon and Steve Milbourne of Sony Music UK, latest project Football Hero. (Behind the scenes video after the jump.) Football Hero is a a copy of the open source clone of Guitar Hero, Frets on Fire, and series of pressure sensors. Soccer players kick balls against the sensors in time with the music.
Yeah, it’s a viral video to promote Kasabian’s new single, but this is pretty cool.
Besides jumping off the Golden Gate Bridge, one of my other unquenchable fascinations is number stations. Why? They’re terribly creepy. Then you learn they’re for honest to god spies.
If you’re not familiar with number stations, they’re shortwave radio stations that regularly broadcast literally cryptic sequences of numbers or letters. Triangulation indicates that some of these stations are typically located on air force bases and other military installations around the world. The number sequences are believed to be one-time-pad messages sending instructions to clandestine agents somewhere in the world. By using shortwave, not only can you broadcast halfway around the world, but building a receiver in-situ is very easy.
When I listen to recordings of these stations, with all the pops, whistles, distortions, and the mechanized voice repeating cryptic sequences I get unsettled. I don’t know why. It’s just bizarre.
Radio Free Berkeley is selling radio transmitters (Brand new obsolete NTSC tv transmitters are also available.) Ruggedized, and small enough to be concealed, the 40W version can transmit 8 – 10 miles.
With one of these and Yuri Suzuki’s QR codes you could create a pretty cool number station.

Last night was DorkbotSF 47 at TCHO. There were three speakers, Timothy Childs, founder of TCHO, talking about how they quantify chocolate and make small testing labs for the Peruvian jungle; Michael Ang (aka Mang) showing off some of his work like Strange Attractor, artificial flowers to attract butterflies, and Blue Flower, yet another LED flower. The highlight of the evening though was Mark Pauline of SRL revealing his plans to build an 8 foot spine robot with a spike on the end. The evening was streamed, so definitely watch Mark’s critique of other spine robots that have been built. It’s around 51:00.
Survival Research Labs wants volunteers. They’re looking for pretty much anything.
I saw an SRL performance at Zero1 back in 2006, “Ghostly Scenese of Infernal Desecration (Formally: Six Flags Over Hell).” It was very loud, and after the show, I dumbstruck. I remember walking back to the car thinking, “What the hell did I just see?” It was “interesting,” and I recommend it to anyone. (Video of the show after the jump.)
If SRL wasn’t in Petaluma, I would totally join.
Vivien Muller (previously) has created a new “plant,” Orkys. This one uses flexible photovoltaics as leaves to light what appears to be LEDs in in the flowers.
I prefer his previous work, PhotonSynthese more though. Aesthetically, it’s more pleasing with the brushed metal stems and the blue leaves, instead of the all black stem and leaves. However, the more flexible materials in Orkys makes it easier to introduce nitnol wires in the leaves for sun tracking. Also, PhotonSynthese does something, while Orkys just sits there and looks pretty. There’s no reason why you can’t have something like this do both.
