(Video link) In non-entertainment news, I am a huge nerd for a cool t-shirt. Sometimes I buy them (usually from Busted Tees or Headline Shirts), and sometimes they find me. The latter shirts are generally men's sizes -- too big and shaped like a rectangle, but so groovy that I don't have the heart to throw it away. Fortunately, there are people out there who know how to fix such things! One of those people is Megan Nicolay, author of Generation T: 108 Ways to Transform a T-Shirt (Workman Publishing) and its sequel, as well as the companion blog. Megan and I hung out in the Workman Publishing office recently to put together a instructional video on how to alter a gigantic potato sack of a shirt into something acceptable to wear in public. After the jump, a quick walk-through of another design.

"The plan was simple. Take a nostalgic NES "duck hunt" Zapper, and retrofit it with a ridiculously powerful laser."
A project from North Street Labs. In case it's not obvious, this is dangerous, and could lead to death or blindness without safety precautions.
Components: "2.1A input buck driver, 2x 750mAh 35-70c Lipo batteries, M140 445nm diode, G2 lens. homemade custom heat-sink, turn key safety switch."
A couple of years ago I was on The Colbert Report showing some fun projects from MAKE, and Stephen fell in love with a project called "The Most Useless Machine." (Watch the episode here.) The Most Useless Machine is a box that shuts itself off when you turn it on. (After the show Stephen hinted that he wanted to keep it, so I gave it to him and he was really happy.)
Make:Projects just posted complete instructions for making your own Most Useless Machine. It's the simplest version yet, and is sure to bring a smile to the face of anyone who tries it.
Last year I saw a video of the "Leave Me Alone Box" built by Michael Seedman. Flip its switch on, and an arm reaches out of a door to turn the switch back off. To paraphrase The Terminator, that's what it does, that's all it does, and it will not stop until its circuit is dead.
I had to have one of my own, so I made one. Seedman's design uses a microcontroller to run two servomotors: one to open the lid, and another to push the switch. This makes for an impressive performance, but seemed too complicated, and actually, his circuit remains powered even when the box is idle.
For existential purity, I wanted a super-simple machine that really turned itself off. So I came up with a single-motor design controlled by a 555 timer chip, with a curved arm that both lifts the lid and flips off the switch. I called it the "Most Useless Machine" and posted it on Instructables along with a YouTube video of the box in action. The project soon went viral, attracting millions of viewers, thousands of comments, and many builds and design variations. Whew!
Along the way, Instructables member Compukidmike came up with an even simpler version that dispenses with the 555 circuitry entirely by using a gearmotor and two switches. The resulting project, presented here, is the ultimate in technology for its own sake, a minimal assemblage of parts that, through its one meaningless act of defiance, speaks volumes.
When NASA's Sunita Williams and Japanese astronaut Akihiko Hoshide couldn't seem to get a bolt attached to the outside of the space station, ground crews came up with a clever solution: Fix the problem with a toothbrush. At Space.com, Denise Chow explains the details:
On Aug. 30, Williams and Hoshide completed a marathon spacewalk that lasted more than 8 hours, but the astronauts were thwarted by a stubborn bolt and were unable to finish connecting the so-called main bus switching unit (MBSU). The stuck bolt forced NASA to add [yesterday's] extra spacewalk.
But, following last week's unsuccessful attempt, flight controllers, engineers and veteran spacewalkers worked around the clock at NASA's Johnson Space Center in Houston to devise a solution to the problem. Using only the supplies available on the space station, the teams came up with creative new tools for Williams and Hoshide to use to install the MBSU.
One was a modified toothbrush that was used to lubricate the inside of the bolt's housing after debris and metal shavings from inside had been removed. Another improvised instrument included a cleaning tool that had been made from wires that were bent back to form a brush, explained Kieth Johnson, lead spacewalk director at the Johnson Space Center.
Snip from the NYT:
To celebrate the 50th anniversary of the New York Mycological Society and the 100th birthday of the composer John Cage, its founder, there will be an exhibition on mushrooms and Mr. Cage’s passion for them on Sept. 7 and 8 at the Cooper Union, 7 East Seventh Street (Third Avenue). Admission is free. On Sept. 8 from 8 to 11 p.m. there will be a performance of some of Mr. Cage’s works with film and photographic backdrops about mushrooms. Tickets benefit the society: $20 to $100, $5 for students, for the show. A pre-performance dinner at the home of the author Eugenia Bone is $200 a person, including the show, or $350 for two, from newyorkmyc.org.
Wednesday, September 5, 2012 would have been the 100th birthday of John Cage. Events around the country commemorating his life are gathered in this LA Times item.

I spent the weekend at the Aspen Environmental Forums, and one of the presenters I got to see there as Thomas Thwaites—a man who built a toaster from scratch. As a project for his design degree, Thwaites reverse-engineered a cheap toaster from the British equivalent of Wal-Mart and used it as a blueprint to build his own. The catch: Thwaites made everything that went into the toaster. He mined the metal. He drew out the wires on jewelry-making equipment. He even found a way to make the plastic casing.
The point of this project wasn't to suggest that everybody ought to be capable of DIY-ing up their own toaster. (Really, if you wanted toast in a post-apocalyptic world, you'd really just be better off with an old-fashioned, pre-electric toaster, which held bread in a metal grille so you could toast it over the fire). Rather, Thwaites was trying shine a light on how much we rely on other people, on their skill sets that we don't necessarily share, and on centuries of technological advance. It takes a village to make a toaster. Or, rather, in this modern world, it takes lots of villages, all over the planet.
Thwaites' project was also an interesting perspective on industrialization. There are drawbacks to producing goods this way. But there are benefits, too. And when we have the necessary conversations about how to make our world more sustainable, we need to consider both sides of the coin ... and how we can get the benefits for less risk.
Cory wrote about this project back in 2009, when it was still a work in progress. The video above provides a short summary of the entire Toaster Project, including an amazing shot of the finished product which did (very briefly) work.
Last week, I posted about the The Gustavademecum for the Island of Manhattan, a delightfully geeky, DIY-made, mid-20th century dining guide produced by a physical chemist for the benefit of traveling scientists and engineers.
One of the key features of the guide was an elaborate series of symbols and letters that provided a lot of information about various restaurants in a small amount of space—and which look like some kind of crazy alchemical shorthand. In the original post, I included a page from the guide, so you can look at that to see the symbols in action.
Hugh Merwin, who wrote the story on The Gustavademecum for Saveur, also scanned a page from the guide's key, which didn't appear in the original story. You can see some of it above, and visit his personal website to see the full key.
Jason Torchinsky of Jalopnik shows how to turn old car parts into a video game controller.
The idea came to me while adjusting the mirrors in a car, and realizing that the little mirror-control joystick was better than many video game joysticks I used. I then had a waking dream of the grand possibilities of playing old videogames with control pads sourced from cars. The dream was a beautiful, fantastical vision of a world we could all achieve. I woke up hours later behind a CVS, and headed straight to a junkyard to make this dream real.
Super-sleuth readers may note that in the final project I used a seat control panel instead of a mirror controller. There's a reason for that. When I got the mirror control pads and joysticks home and tested them, I uncovered one of the auto industry's darkest secrets: the "up" and "left" directions on mirror controllers are THE SAME DAMN THING. They're wired together! Think of all the times you've thought you were adjusting your mirror up, not left, thinking you were hot shit? IT'S ALL BEEN A FILTHY LIE. So I soon learned to look elsewhere. Luckily, 70s-80s American cars provided the solution, since they're full of funny little chrome joysticks for seat controls and other various duties.
I didn't want to experiment with a liquid patch because I couldn't be sure if the solvents would interfere with the composition of the sleeping pad, so this option was attractive. The instructions are clear and application was simple. After preppng the area with alcohol, I peeled the backing off and pressed the tape over the problem area. The tape is tough but flexible, and is transparent. It sticks very well and the sleeping pad now stays at pressure perfectly.
[Video Link. Warning, may totally creep you out if you love cats. ]
Dutch artist Bart Jansen had a cat named Orville that he loved very much. When Orville died, he did what any cat-loving guy would do: transformed his deceased kitty pal's corpse into a radio-controlled DIY taxidermy helicopter. WAIT WHAT
The Orvillecopter, half cat, half machine. Named after the famous aviator Orville Wright. He was killed by a car. After that he received his propellers posthumously. This is Orvillecopter's first test flight, Soon to be flying with the birds. Oh how he loved birds. He will receive more powerful engines and larger props for his birthday. So this hopping will soon change into steady flight. For the catlovers: it is a tanned hide, just like the shoes you're wearing. For the RC lovers: it's a Lotus T580 (still)
In the New York Times today, Brian Lam (formerly of Gizmodo, now the creator of Scuttlefish and Wirecutter) writes about OpenROV, a low-cost submarine designed to be an affordable tool for "curious students and amateurs, as well as provide a highly valuable shallow water tool for explorers and scientists."
This month, NASA engineer Eric Stackpole hiked to a spot in Trinity County, east of California’s rough Bigfoot country. Nestled at the base of a hill of loose rock, peppered by red and purple wildflowers, is Hall City Cave. For part of the winter the cave is infested with large spiders, but is mostly flooded year-round. Locals whisper the cave’s deep pools hold a cache of stolen gold, but Mr. Stackpole isn’t here to look for treasure.
He had, under his arm, what might appear to be a clunky toy blue submarine about the size of a lunchbox. The machine is the latest prototype of the OpenROV–an open-source, remotely operated vehicle that could map the cave in 3D using software from Autodesk and collect water in places too tight for a diver to go. It could change the future of ocean exploration. For now, it is exploring caves because it can only go down 100 meters. But it holds promise because it is cheap, links to a laptop, and is available to a large number of researchers for experimentation. Indeed, the OpenROV team hopes to start taking orders for OpenROV kits on the crowd sourced project site, Kickstarter. Going for $750, the kits include laser cut plastic parts and all the electronics necessary to build an OpenROV. (Users will have to bring their own laptops to view the onboard video feed and control the machine. They’ll also have to supply their own C-cell batteries which power the sub.) The subs are expected to be available by the end of summer.
I created the skeleton of a skeletal Lepidoptera. The Death's Head Hawkmoth (Acherontia atropos), seen in The Silence of the Lambs, has a skull marking on its back. I made a full human-like bone structure for the moth, with the grinning skull protruding from its back. The model is very thin, yet sturdy and flexible. Detail level is fantastic, and the natural texture of the 3d printing process gives it a bone-like appearance that works wonders. Yes, moths don't have endoskeletons, that's the whole point...
A styrofoam-and-acrylic model of Osama bin Laden's compound that was used to plan the May 2011 raid that killed the al Qaeda leader has been declassified by the Pentagon.
CNN reports that the model of OBL's building and surrounding farmland in Abbotabad, Pakistan was built over a six-week period, and then was taken to the White House to brief President Obama on plans. After the raid, it sat on display in the lobby of the National Geospatial Intelligence Agency in Fort Belvoir, Virginia.
Until last week, the model was considered classified and only those working or visiting the building could see it.
Now it is declassified, and agency officials wanted to bring it over to the Pentagon for a brief time to show it off to Department of Defense "customers" to highlight what the National Geospatial Intelligence Agency can do for them, according to an agency information sheet.
The to-scale diorama helped the Navy Seals literally measure the steps it would take to get to bin Laden.

Participants in a rocket competition cheer after their rocket was successfully launched during the rocket festival known as "Bun Bangfai" in Yasothon, northeast of Bangkok, May 13, 2012. The festival marks the start of the rainy season when farmers are about to plant rice.
My kids were grumpy at breakfast this morning, so I had this idea to make a quick banana peel trucker hat for the banana to wear using the peel of the banana. This cheered them up and it made the banana look relatively hip.
How to make:
1 or 2 bananas. One to make the hat, one to model the hat. This could also be made using one banana. Carve the shape of the hat using an x-acto knife. Leave one of the banana peel sides longer, to make the rim of the hat. Most bananas come with a little sticker. Use this sticker to serve as the logo on the hat, if you want your hat to have a logo.
Simple project, takes about 5 minutes yet the memories will last a lifetime.
A worker paints a single-seater submarine designed by Zhang Wuyi and his fellow engineers at a shipyard in Wuhan, Hubei province May 7, 2012. Zhang, a 37-year-old local farmer, who is interested in scientific inventions, has made six miniature submarines with several fellow engineers, one of which was sold to a businessman in Dalian at a price of 100,000 yuan ($15,855) last October. The submarines, mainly designed for harvesting aquatic products, such as sea cucumber, have a diving depth of 20-30 metres, and can travel for 10 hours, local media reported.
The ShopBot is a low-cost CNC, or computer controlled router. Think of it as a large-scale milling machine. It is great for small-scale production runs of machine parts in wood or metal. A friend of mine used his ShopBot to cut the gears and mechanism (other than the chime) for a full-scale replica of a grandfather's Clock. ShopBots (and their kin) can also fabricate extremely detailed 3D contour maps (whole cities!), and other intricate 3D surfaces.
We have one at the design school I teach at. It can cut anything programmable like the hull plates for a full scale sailboat. On a big boat, each plate of the hull is different shape, but the ShopBot just follows its orders and spits them out ready to install. It is very accurate. Hey, you can even equip it with a pen or the like, which permits very intricate drawings. The cheapest Shopbot is the small Shop Bot Desktop for $5,000. They are getting cheaper every year, but if you only need one occasionally, you can buy time on one at shared workshops like Techshop.

We've talked here before about the extremely important (and often-overlooked) DIY aspect of science. Scientists are makers. They have to be. The tools they need often aren't available any other way. Other times, the tools are available, but they're far more expensive than what you could construct out of your own ingenuity.
In this video, researchers at Cambridge build LEGO robots that automate time-consuming laboratory processes at a fraction of the cost of a "real" robot.
