Today on Offworld we debuted One More Go, our newest regular column (joining Jim Rossignol's launch column Ragdoll Metaphysics) from former Edge editor and current games consultant Margaret Robertson. In her debut column, Margaret found an interdimensional rift split open from a misguided New York Times Crossworld puzzle that saw Atari, rather than Nintendo, becoming the modern day global games powerhouse.
Elsewhere we saw a Game Gear that played Atari 2600 games and a Wii that played like a theremin, saw Left 4 Dead makers Valve tell us precisely how pitiful we are against a zombie horde, and played a World of Warcraft April Fools joke to its full conclusion.
Finally, we rounded up digital download Black Friday sales from Microsoft and from Sony that both feature games typifying what it is Offworld is all about.



On Wired's How-to Wiki, they decided to try their hand at building Mike Golembewski's Scanner Camera project, featured in MAKE Volume 14 and in the Sept 19th episode of Make: Weekend Project (see both below). Charlie Sorrel, author of the piece, did what looks like a nice job with the build, but the results look like something from a questionable episode of Ghost Hunters (if that's not redundant).
We asked Kip Kay of Weekend Projects for any tips he can offer Charlie:
Here is what I discovered about focusing. You have to really play with the focusing elements and the distance to the object. I got some pretty good results as seen in the video from about 4 feet away. But the results were nothing like what the original author, Mike Golembewski achieved. I think he had an actual lens on his rather than a magnifying glass for the pictures in the article. (He did mention he had built a better one)Before taping the camera to the scanner, you should tape on a piece of
tracing paper over the back which allows you to see the image and get it
focused properly.

Enlightenment in the checkout line. After forgetting the liter of olive oil that I went to the store to get and had to return for, I saw on my return trip, down on the bottom shelf of the rack in the chute to the register was a ratty box of beat up plastic fans. Summer is long gone, so they were marked down to $1. Cheap enough to grab two and chuck them onto the conveyor belt. With the oil and a few other shiny objects that I had missed on my previous run.
On the way home, I realized that these little fans might just be a gold mine. A dc motor would cost about a buck, a battery pack with a switch, the same, and a hub for the shaft of the motor that you could attach a wheel to might just be hard to make quickly. Action packed with lots of features and priced to move. The personal fan, battery pack, motor holder, hub, what could you do with this if you had a dozen? two dozen? a hundred? a thousand? What kind of projects come to mind? I was thinking little car, attach a cd to the hub, but there are other ideas as well. What are the ideas you think of when you see these? Certainly they could be used to explore fluids and movement of air. How about cooling and thermodynamics? Screw into the plastic, and you have a mountable system. Hack into the switch, and turn it on and off based on a sensor with an Arduino.
Just what could you do with these? Have you tried any projects with them? Do you have any in a drawer in your house? Do they have them at the local junk store/gas station/thrift shop/lost and found?Try out some projects with these little fans. Make some pictures and post them in the Make Flickr pool. Make a video, post it online and use the tag dollarfan
Post your ideas in the comments and lets see what we can come up with!

Canstruction '08 features some very awesome works built entirely from canned foods -
Canstruction is an international charity competition that opened last Thursday at the Winter Garden and Courtyard Gallery of the World Financial Center, featuring giant structures built entirely out of cans of food. Top architectural and engineering firms in over 100 cities across North America participate in Canstruction, collecting millions of pounds of food for local food banks — the New York City show features local architectural and engineering talent. At the close of the competition, all of the food from the show will be donated to City Harvest.- Canstruction

My friend William Gurstelle is a frequent contributor to MAKE. He's one of the best all-around DIYers I know, has an intense curiosity about everything, and is really fun to hang out with. You can get a taste of this human dynamo by picking up his new DVD, Barrage Garage, which is full of explosively fun projects. Here's an excerpt that shows how to make a smoke bomb.
Best-selling author William Gurstelle (Backyard Ballistics and MAKE Magazine contributing editor) blends science, humor and the Barrage Garage Gals into an explosive new instructional DVD. It's MythBusters meets Baywatch. It's the hobbyist's ultimate video guide to all things that go boom. Bill shares the origin, historical significance and simple step-by-step instructions for safely creating high-voltage experiments including the Night Lighter 36 Taser-Powered Potato Cannon, Smoke Bombs, a Jam Jar Jet engine, and the world famous Mentos Fountain. Then he turns it over to the Barrage Garage Gals to help do some field testing and high-test high-jinks ensue. Dale Dougherty, Publisher of MAKE Magazine raves, "Bill Gurstelle's enthusiasm and knowledge come through on Barrage Garage. Bill makes you want to build something to amaze your family and friends. It's like magic, only there are no tricks involved."BarrageGarage

Street Anatomy has launched a cool new sister site, Think Anatomy.
I found that reading an anatomy textbook, sitting in lecture, and dissecting in lab weren't enough to really master anatomy. So I turned to the Internet to find resources like dissection videos, interactives, games, quizzes, etc., to supplement my study material. It took a lot of time to sift through the results and put together a list of valuable online anatomy resources. That's where the inspiration to make Think Anatomy started. I wanted to make a site that anatomy students could use to find study aids without having to use a major search engine like Google. So after many many hours spent searching, reviewing, and categorizing anatomy sites, Think Anatomy is finally ready.Read more | Permalink | Comments | Read more articles in Kids | Digg this!
My solo exhibit at Thinkspace (February 13-March 6, 2009) is entitled Dreamgirls and Ukes. In this show, I will feature a new series of oil paintings of playful, iconic nudes and introduce some new characters (in addition to my cats, pierrots and monkeys): a lion, a tortoise, and large flying insects. Ukuleles will play a role in these narratives, giving the works musical ambience. Some of these dream sequences will take place in nature, others in curtained rooms.Dreamgirls and Ukes by Amy CrehoreI am also painting over a dozen antique ukuleles as part of this exhibit. Most of these instruments are from the American ukulele boom of the 1920’s. I have personally hand-picked a collection that represents a variety of styles and designs including banjo ukes, mahogany and koa ukes, as well as art deco novelty ukes. On these ukes, I will incorporate motifs from my paintings, plus I’ll be adding creative type and logo design. My long-time music partner, Lou Reimuller, is also a luthier and he has lovingly restored each of these instruments. These ukes are all “players” as well as fine art objects.

All parents should be trained as toy mechanics before they accept the gig. For, no matter how many high-quality, wooden, German toys you give your young ones, at some point they're going to fall in love with a fragile, mass-produced hunk of plastic. Knowing how to fix it will save money and forestall its trip to the landfill.
This is my son's Buzz Lightyear action figure. (I'll admit mine's in the original box in the garage.) The wires that connect the upper arm "laser" button to the LED in his forearm are routed through his elbow joint in a less-than-perfectly engineered fashion. They've been severed four times. The first three times, I soldered them back together and kept them running through the elbow joint. The fourth time, I decided I'd had enough of that, drilled some holes, and routed the wires outside the elbow entirely. With a bit of braided wire tubing it looks pretty cool. Doesn't Robosapien look sort of like this?
About a year ago these figures became hard to find in toy stores. When they returned they had a poor substitute for Tim Allen doing the voiceover. It's pretty unholy sounding. That's another reason why I'm willing to repair this guy as many times as necessary.

The cause of the crumbling economy is the city of NY where all the banks are located, the ones that are crumbling. I know this may sound silly, but I believe that when a city destroys a baseball stadium, nothing but bad things happen. Look at Seattle's Kingdome for an example. I don't need to say any more. The meaning is obvious.

One of the new kit releases I got a big kick out of at Maker Faire Austin was the HexPummer Lantern from our compadres at Solarbotics. This is an add-on to their popular HexPummer, a kit version of a cool BEAM circuit that creates throbbing LED light that "PUMMs" when darkness falls and the circuit slowly dumps the power from the solar cell and rechargeable batteries that have been soaking up and storing the day's sun. Put this inside of a handsome little laser-cut Japanese lantern with geeky silhouettes (or seasonal ones) and you have the HexPummer Lantern. This is a great entry-level kit, something that the builder will have fun showing off when s/he's done making it.
Solarbotics even made special MAKE and Maker Faire Austin Lantern kits. These kits, and the HexPummers, are available in the Maker Shed.

Just spotted on Twitter (search: mumbai or #mumbai) and via chat sessions here in the Boing Boing tv studio: Attacks in Bombay (NYT), and here's a snip from the Times of India report:
Terrorists struck at India's financial capital late Wednesday night as at least seven near-simultaneous firings and explosions rocked areas in the vicinity of posh hotels in South Mumbai, leaving ten persons dead and several injured. ( Watch )The best live streaming TV coverage I've found is on CNN-IBN (CNN's partner in India). I'm watching the stream now, as I type. Mumbai Metblogs has a post up, I'd imagine they'll be posting more.Armed with AK-47 rifles and grenades, a couple of terrorists entered the passenger hall of crowded Chhatrapati Shivaji Terminal (CST) railway station and opened fire.
Ten people were killed in firing at Mumbai Chhatrapati Shivaji Terminus (CST) station, police said. Over 30 people were injured in firing at CST, a senior police official said.
Director General of Police A N Roy said at least two terrorists were holed up inside the Oberoi Hotel where firing was on.
Three people, employees of Taj Hotel in South Mumbai, were killed after being fired upon by terrorists and an equal number of people died in a bomb blast in a taxi at Dockyard Road.
One of the BBtv crew members is from Bombay, and I think he looks to the Times of India for breaking coverage of events such as this -- looks like they already have a lot of news online. Neha Viswanathan at Global Voices has a comprehensive roundup of what's happening (thanks, joncamfield). Toronto Globe and Mail coverage here. (thanks, howlabit). Al Jazeera's coverage is here. A number of independent blogger/journalist types in Bombay right now are posting a lot of updates to Twitter, someone just recommended Dina Mehta, another points to Karishma, both of whom are near the attack site. PHOTO: A blogger named Vinu in Bombay is uploading photos of damage from the attacks, including the image above; more photos are being uploaded as I type this post (thanks, Maurice Reeves).
Please add other pointers in the comments thread.

Cinematch has, in fact, become a video-store roboclerk: its suggestions now drive a surprising 60 percent of Netflix’s rentals. It also often steers a customer’s attention away from big-grossing hits toward smaller, independent movies. Traditional video stores depend on hits; just-out-of-the-theaters blockbusters account for 80 percent of what they rent. At Netflix, by contrast, 70 percent of what it sends out is from the backlist — older movies or small, independent ones. A good recommendation system, in other words, does not merely help people find new stuff. As Netflix has discovered, it also spurs them to consume more stuff.Basically, that entire paragraph explains the issue. A good recommendation system does two things: it gets people to consumer more -- and it introduces them to stuff they might not have heard about otherwise. But, that second part is not necessarily the same as the first part. Many people assumed, incorrectly, that the greatness of such "long tail filters" was that it would drive people to consumer more down the tail -- but as Netflix is seeing, the good recommendation engine drives people to consume more content in both the head and the tail.
Also camped out in the tribal areas are Al Qaeda, and if he's still alive, almost for sure Osama bin Laden.

Mikey Sklar has posted a nice hack for bringing a dead Roomba back to life:
I repaired my $60 Dirt Dog battery with just a AA battery and some tape. We start off with a Dirt Dog battery that has a voltage of 15.87V which is indicative of a bad cell. When we complete the repair we are at 17.12V and that is without even charging the pack.

The Arduino open-source microcontroller platform can be programmed and equipped to perform a nearly endless list of functions. It's likely the best all-around centerpiece to a modern electronics project. But one of the tasks Arduino is best used for is straight-up fun - the open design means there's an Arduino board suitable for almost any project, and a wealth of add-on "shields" extends its abilities with ease.

It's 1951, and America fears Communism and the Bomb. Since the Johnsons, a working-class Midwestern family, can't afford a Thanksgiving turkey, they decide to spend an evening writing up what they're thankful for, and share their thoughts around the dinner table.A Day of Thanksgiving (1951)Unlike almost every other Cold War educational and industrial film, this film doesn't equate freedom and happiness with material things. Made by Centron, the same visionary company that spawned Herk Harvey and his "Carnival of Souls," and written by Margaret "Trudy" Travis, one of the few women creating ephemeral films at the time, it's deeply patriotic, yes, and anti-Communist as well, but it runs counter to many of the Fifties clichés we hold dear.

I've just finished listening to Tony Benn's More Time for Politics: Diaries 2001-2007. Benn was a long-serving left-wing British Parliamentarian who also served as Secretary of State and has been key in the anti-war movement. I was only vaguely aware of him until I saw his amazing appearance in Michael Moore's fantastic movie Sicko, and since then, I've found him popping up all over the place.
This volume of Benn's diaries covers the 9/11 attack, the wars in Afghanistan and Iraq, the Hutton inquiry, and many amazing turns and twists in domestic and global politics. Benn -- now 83 -- is incredibly insightful, thoughtful, and principled in his analysis of these events, and is an inspiring whirlwind of activity as he packs his days with interviews, position papers, lecture tours, private meetings with everyone from Kofi Annan to Iraqi dissidents. In between, he's absolutely charming with his grumbles about his flagging health and energy, his search for his favorite frozen pizzas, his overwhelming pride in his family, and his ruminations on an extraordinary life in politics.
Benn hails from an era in politics characterized by thoughtfulness, civility, passion and deep commitment to principle. Listening to him narrate his diaries is an education in what politics can and should be, and what it means to give yourself over to public service. The world's a better place for Benn -- and I feel like I'm a better person for having lived inside his diaries for a few hours.

I have a medium-sized quince tree, which is very productive. For a while, I didn't know what to do with quince until last year when I began making quince paste. The Spanish call it dulce de membrillo and feature it with manchego cheese.
As quince ripens, the skin turns from green to yellow. Quince have a grey-white fuzz, so the first thing is to give the quince a good scrubbing. Then, place the 4-5 quince in the oven to bake until they're cooked through. Once they've cooled, peel them and remove the seeds. This is somewhat tedious and messy. (Some recipes call for boiling the quince.)
Next, blend the quince in a food processor until the pulp is smooth. Remove to a saucepan, measuring equal amounts of sugar and quince puree. Cook thoroughly, a couple of hours or more. Slowly, the color of the quince mixture will begin to darken.
My wife, Nancy, put some of the liquid quince at this stage over ice cream and she thought it tasted like butterscotch. She decided to save some in a jar for future desserts.
After stovetop cooking, scoop the quince mixture into a baking dish lined with parchment paper. Warm the oven and put the dish in it. Leave it overnight or longer until it begins to turn rose-red. The idea is to let the quince dry out and harden.
Next, with a spatula, try to separate and remove squares of the mixture on to wax paper. The bottom side of the mixture will still be soft but I find that it continues to dry later on. Fold the wax paper to cover the quince paste and refrigerate. It keeps for months and I think it gets better over time. If you want to give some as a holiday gift, place the packet in a plastic bag.
To serve, scrape the paste away from the wax paper and place in a shallow bowl. Surround it with cheese and crackers and fresh fruit for a wonderful appetizer or snack. You won't want to move to the main course.
So, where does this leave us? Users must have passwords, so why fight it? Why not admit that its where we have to be and make it a familiar (but secure) process, so that users can actually safely use passwords, phishing-free?Do Passwords Scale?The answer to this is deeply sad. It is because we have done a fantastic job on usability of passwords. They’re so usable that anyone will type their password anywhere they see the word “password” with a box next to it. Phishing is utterly trivial because we have trained the world to expect to be phished every time they see a new website.
Of course, we can fix this cryptographically - that’s easy. But let’s say we did that. How do we stop the user from ever typing their password into a phishable box from this day forward? So long as they only ever type the password into the crypto gadget that does the unphishable protocol, they are safe, no matter who asks them to log in. But as soon as they type it into a text box on a web page, they’re screwed.
So, this is why passwords are the worst usability disaster ever.

Innovation in America... A gathering storm? @ The Economist-
LISTEN to the growing cries of despair coming from some leading business people, and you might imagine that corporate America’s competitiveness could be the next victim of the global financial crisis. But Jeffrey Immelt, the boss of GE, the world’s largest industrial firm, sees opportunity amid the woe. “Companies and countries that really play offence vis-à-vis technology and innovation are going to come out ahead,” he said this week at an event in New York to present GE’s coming innovations in health-care technology.Read more | Permalink | Comments | Read more articles in Culture jamming | Digg this!
With those words, he touched on a debate that has been heating up for many months. Even before the financial crunch began, many businessmen were worried that America was losing its lead in innovation to India and China. They were particularly upset that Asian rivals had been investing with more gusto in teaching young people mathematics and science, and in advanced scientific research. America’s National Academy of Engineering even issued a report last year, “Rising Above the Gathering Storm”, arguing that America’s “economic and strategic security” was in question because of lack of investment.

Mikey's HOW TO - iRobot dead cell battery fix...
I have three iRobots which help clean our house. I bought them about two years ago. As the one year warranty was coming up I called iRobot and asked them to help with various issues. They basically replaced all three of them. Now that I am at the one year point with the replacements I'm running out of options as things break. I can either fix it myself, or buy more shit. Obviously, I don't want to pay for anything. This morning I took apart the battery pack in the Dirt Dog vacuum cleaner. After about 30 minutes of cutting, sawing, and taping I had a battery pack that was performing like a new one. Now instead of getting 10 minutes of lousy vacuuming I get over a hour of powerful cleaning. This saved about $60 which is the cost of buying a new replacement pack from iRobot.

Gio sent in a link to this interesting preamp. The builder was able to make the preamp with parts on hand. I'm not sure I would have the tubes, but the rest of the parts are fairly common. [Thanks Gio]
I was pleased with how well it turned out, at 30 bucks it looks pretty professional with the solid gold plated jacks on the black case. A neat feature I added later on is the ability to adjust the brightness of the front LED. The yellow LED is to indicate that the tube filaments are active.

After having such a great time making the Gakken Inchworm, we decided to try the Gakken Mechamo Centipede. It's nicely packaged, too, and also comes with its own tools; it just needs 6 batteries.
This kit only had directions in Japanese - there was no English version included. Since we had experience with the Inchworm, we decided to see if we could put it together just using the pictures, but we found it helped a lot to look at the English instructions periodically. (If you decide you need the text in English, it's available as a PDF through the Maker Shed Centipede link - you do need to download the Japanese font to view any text at all, even the English, which is odd, but it only took a minute.) There was an errata page in the kit that had corrections for steps 5 and 7, but the errata page looked the same as the page in the Japanese instructions. The online illustrations for steps 5 and 7 were missing some little spring washers, so we assumed the kit had come with updated instructions.
The little cranks are numbered; take care to assemble them in the correct order. They also have to be aligned in a specific configuration for the leg movement to work correctly.
This was definitely a harder build than the Inchworm was. So many legs! There were just more parts in general, you had to keep track of the numbered parts, and it was a more complicated build. But again, it's a forgiving kit, you can backtrack easily if you've put something in backwards. One battery pack wire came loose during the build, but it just took a quick solder to fix it and we were good to go. When we put the batteries in for testing, we found that one of the leg cranks kept getting hung up on a nut that was sticking out just a hair too far - we had to take out the spring washer behind the nut to fix that.
All in all, it was a fun build - it might not be the best kit for a first project, depending on the kid and their level of patience. The motion is totally awesome! I lived in Korea for a while when I was a kid, and one morning there was an amazing many-legged bug that kind of flowed across the bathroom floor - this reminded me of that bug, the motion is very realistic (but mechanical, and slower!).
The Gakken Mechamo Centipede kit is available through the Maker Shed.

The BeagleBoard is an incredibly little embedded system. It's Linux-powered, easy to hack, and has lots of connectors; everything from an expansion port with GPIO/I2C/SPI on up to HDMI. Pair it up with Arduino (don't miss our great Arduino gift guide), and you're unstoppable.
Enrique wrote in to tell us about the amazing BeagleBoard-powered project he made for his son:
For Halloween, my son wanted to be Iron Man. In about 2 months time, I integrated various gadgets into a store-bought costume. The most powerful components were BeagleBoard and Arduino. If I had more time, I would have added an overhead display in mask, a webcam for night vision, a 3G modem connected to BeagleBoard and maybe more. ;)
The suit is really tricked out:
- Repulsor Air - Blows air with CO2 air pump on hip and hose back to his hand.
- Repulsor Missile - Using CO2 air pump can also launch a paper missile.
- Repulsor Sensor/Light - A magnetic switch sensor lights his repulsor hand light and fades out and in his glowing eyes. Arduino handles this effect.
- Repulsor Sound Effect(s) - Originally not working. Worked around problem by using right-mouse, middle-mouse button and configured Elightenment17 to playback sound effects using Mplayer script. Mouse buttons activated by Arduino Digital output triggered by sensors.
- Arc Reactor - A LED night light from Costco embedded in his chest.
- BeagleBoard: Powerful Computer - With BeagleBoard already running in JARVUS box on my son's back need to add other features. Possibilities: Web cam, mobile router with hotspot and a head-mounted display, VoIP, streaming video of Iron Man view.
- Arduino: Super Input/Output Board - Handles repulsor effects but can add other sensors to enable even cooler special effects!!

Sun's approach--at least the way I'm reading it from Jonathan Schwartz's statements, is about making the software totally free and trying to sell support and hardware. This clearly diminishes the value of the products and doesn't offer a mechanism that encourages people to pay for software.It's difficult to see what Rosenberg is worked up about here. Sun seems to be following pretty closely an economically sound approach to a market: using infinite goods (software) to make scarce goods (hardware and services) more valuable. That's a lot more reasonable than using infinite goods to try to get people to pay for more infinite goods. There's no reason why Sun needs to encourage people to pay for software, and there are many reasons why they should not try to make people pay for software.
It also puts an unnecessary burden on the notion of open source--such that if Sun is wrong, everyone else will look wrong too.Why? If, as Rosenberg notes elsewhere in the article, Sun's open source strategy is different than other companies', then such a failure should be seen as a failure of Sun's model, not a strategy of embracing open source. There are plenty of reasons why Sun may (or even is likely to) fail in this endeavor. The Sun brand name has been tarnished. People may not find the hardware or services Sun is selling as providing enough value compared to alternatives (even with the software included). On the whole, it's not clear what's compelling about Sun's offer compared to the alternatives, and that's its biggest challenge. But that hardly reflects poorly on open source software or on the idea of not selling software.

R Scott's analog MIDI drum machine puts circuitry from an old organ's rhythm section under digital control -
The 8 knobs on the top of the case control Master Volume, Kick, Clave, Snare, Conga, Low Tom, High Tom, and Hi-Hat levels. The two LEDs indicate power and midi activity.MIDI control was implemented via a custom kit from Highly Liquid. Combining pre-existing analog synth boards with new controller hardware is an awesome idea that coud be applied in a number of creative ways. Head over to the site to hear samples and get more of the story - analog MIDI drum machine
[…]
The drum sound circuitry was taken from a broken old Farfisa organ. I removed the entire rhythm accompaniment assembly and later built a power supply for it, turning it into a stand-alone drum machine.

It's a bird, it's a plane, it's a ... boat? Technically, it's a planeboat. And to Dave Drimmer of Fort Lauderdale, Fla., the live-aboard craft was home for 20 years.
The vessel has a colorful history. Its name, Cosmic Muffin, comes from singer Jimmy Buffett, who caught a glimpse of the yacht on a sailing trip and wrote it into his 1992 novel, Where Is Joe Merchant?
But the planeboat started out as infamous aviator Howard Hughes' personal Boeing 307 Stratoliner in 1939. Rumor has it Rita Hayworth had a hand in decorating its 12-foot-wide interior.
In 1964, under different ownership in Florida, the plane was grounded by Hurricane Cleo.
It didn't stay on land for long. After buying it as scrap for $70 in 1969, the vehicle's new owner decided to salvage the ailing aircraft and turn it into a motor yacht. Then in 1981, current owner Drimmer answered an ad in the local classifieds: "Unique houseboat, great bachelor pad."
"It was in horrible condition and almost everyone tried to talk me out of buying it," Drimmer says, "but it had a strange and wonderful appeal that compelled me to grab it."
With trashed floors, a leaking, rotted hull, and no motors, propellers, or rudders to speak of, Drimmer had his work cut out for him just making the boat livable. With the help of friends, he stopped the leaks, rewired the electrical system, installed a water heater, air conditioning, and fridge, and renovated the head (that's bathroom in boatspeak). Powerful motors installed in recent years have made it seaworthy once again.
Drimmer lives on land these days, but the planeboat is docked nearby. He's always willing to give tours and charters, and to talk on and on about the strange conveyance he once called home. He kinda misses the old girl.
"My house doesn't move around at all," he says. "I really enjoyed the motion of the ocean. And being in a fuselage sometimes felt like flying."

Astronaut Dr. Don Pettit demonstrates what is likely the most convenient method for enjoying a beverage in space - using a simple cup with airplane-wing-like shape which uses a liquid's surface tension to draw the beverage evenly towards the mouth -
When Dr. Don Pettit lived aboard the International Space Station in 2002, he became known for his "Saturday Morning Science" sessions, during which he would demonstrate really cool, simple microgravity experiments.Not sure if it's safe enough to use around a sensitive control panel, but very cool all the same. - Sunday Morning Science Read more | Permalink | Comments | Read more articles in Science | Digg this!Earlier this month, Pettit returned to space, this time as member of space shuttle Endeavour's crew on a mission to upgrade the outpost.

Here is a great use for an empty soda can. Just be careful of those extremely sharp edges when working with any thin metal, especially aluminum.
Soft drink cans are easily recyclable as scrap metal, but I fancied trying something a little more direct - a simplified form of tinwork.All that's needed for this project is a strong pair of scissors, a cork-backed table mat, a pointed object (a scriber or just a ballpoint pen), a little bit of tape and some fine abrasive paper. Plus of course an empty aluminium drink can.....

Flowers by Jan van Nuenen was created using a Monome controlling Ableton Live via a max/msp patch called boiingg. I really like the combining of music and video into one piece of performance art.
Live generates a string of midinotes with velocity 0 to 20 and back to 0. The velocity channel is used to tell the game engine which frame of the loop will be displayed. In this case, a loop of a growing flower is playing from frame 0 to 20 and back. So you can re-animate the flower by changing the velocities. Framerate can be changed by changing bpm in live. This technique also allows you to change in and out points of the loop live.

Another thing I have a vague recollection of was an announcement in August or September that Asus was going to offer an Eee PC with a built-in EVDO modem and a service plan. This started the thread about $99 netbooks. The product was supposed to ship in October but I can't find any evidence of it. Do you know what happened? Did they ship? If not, is it still planned?
I have an idea for a business built around a new Top Level Domain or TLD. It wouldn't matter what the name is, it could be .xyz or .x98 -- I'd just like to plunk down some money and create a little economy around domains all ending with the same three letters. I seem to remember reading somewhere that ICANN was going to open this up, that you'd have to make some kind of relatively large payment to them, and offer a business plan that indicated you were doing something honorable.

Tim is a high school senior doing an independent study. An important part of his work is to learn and document his process with the Shopbot.
In order to improve on this first design I modified the top to be 14 inches in diameter as opposed to the original 16 inch diameter, which some people said was too big. I used part wizard's vector modification tool to alter this. I had recieved positive feedback on the handles, so I kept those by sliding them towards the center in part wizard. I cut too more legs for this new top to sit on using an irregular piece of scrap plywood. By modifying the angle of the toolpath I could very efficiently use the wood. I found that plywood is thicker than avantech when I tried to fit these legs together, they were much more difficult and ended up slightly warped, creating a tip in the stool. The top still slid on just fine.
Tim was enrolled in the Engineering the Future course several years ago. The ETF curriculum was developed by the Museum of Science in Boston. and learned some effective ways of working with the Design Process.

Antique voltmeter displays current air quality from the web - By Tom Igoe...

1) It's not a hurricane so Anderson Cooper of CNN is unable to position himself in the middle of the storm for optimal drama. In other words, TV anchors can't get wet and windblown, while viewers worry about their safety. The state of the economy is a disaster but not a natural disaster. Nobody's leaving the studio for this one. There's no place to go.
2) It's like a war and we keep losing ground each day. In the place of casualties, we have falling stock indices but it's hard to show the real damage. There's only so much you can do with oversized charts to tell a story. The war on terrorism featured a real enemy. We've just never been able to find them, no matter who goes after them. (Maybe it's not so different.) Campbell Brown ("No Bull, No Bias") should say that what the capitalism's finest did to themselves and to us was worse than any terrorist could have imagined.
3) Few CEOs, fewer economists, and almost no one in the financial industry, want to step forward and say with conviction what will happen. A year ago we couldn't get them to stop telling us what great things to expect in the next quarter. Not now. They don't know what's coming and they aren't willing to say even that much. They are MIA. Insider information is at an all-time low.
Memo to all American CEOs: don't presume in ten years' time to write business books about your leadership skills; maybe there's a gripping survival story to be told about how you held on to your job.
We want them to face the music. Even the Watergate hearings, which had a large cast of characters, were compelling to watch day after day.
4) There is not a President at the center. Bush is just not there. Like us, he's watching TV to find out what to think. Reporting from the White House doesn't have any relevance today. Moreover, the satisfaction in blaming Bush for everything is diminishing.
In addition, with the election over, reporters can't simply ask the candidates to react to the day's bad news. It seldom produced much insight anyway but it filled time. Now Obama is filling time, and he keeps repeating that "there's only one President" but there's really not a President. There's a leadership vacuum waiting to be filled by Obama. (BTW, this story is much bigger and more important than Obama's election and I think he understands that.) Bottom line is we're waiting for a central figure to emerge.
5) Real experts are hard to find, especially ones with big hair. So over-present talking heads such as Suze Orman ramble on and on in front of Larry King and others. Here's an incredible ramble from Suze Orman on CNN:
People feel they need medication because they are panicking. It’s as if the economy right now is in the I.C.U. unit of a hospital. We are in intensive care and they are throwing everything type of medication at us to cure what is going on. They are panicking because why? Nothing is working. They tried this, it didn’t work. They tried that medication, it didn’t work. They are running out of prescriptions to give it. We are going to be in the I.C.U. unit for a while. Eventually, I don’t know when that will be, six months, a year, year and a half, we will get out, we’ll be in the hospital then. We’ll stay in the hospital for about a year or two. After another year or two we will end up in rehab and then we’ll be okay. This is a long stretch. People have to stop panicking.Makes me think of Amy Winehouse singing "They try to make me go to rehab, I say no, no, no." Rehab is taking place over on CNBC.
CNN link
6) Where are the winning and losing teams? We have learned more about Al Queda cells and Saddam Hussein's Elite Guards than about the people in power behind CITI, Goldman Sachs, Lehmann Brothers, AIG, etc. We know more about the New York Jets than we do about CITI Bank. Are the slow-moving Detroit Manufacturers competing head-to-head against the fast-talking Wall Street Financiers? Please tell us more about these teams as we're entrusting them with such large amounts of public money. Maybe we need to start thinking that, as with football, we care because we're betting on teams to win. We have our money at stake.
7) I can almost hear producers wondering each night if there isn't a better story to lead with. "Isn't there a story we can do on Sarah Palin? Like her or hate her, people can't get enough of her." At least that appears to be the thinking behind her getting the most air-time in the week following the election. Would you rather hear about Sarah Palin pardoning a turkey or David Gergen saying no one knows what to make of the economic mess? At least, the Palin piece will have something interesting going on in the foreground and the background.
8) "Why can't this be happening to Russia or China? If it was only happening there, and not here, we would know how to cover it." CNN would send Christiane Amanpour there. "Live from...". We don't have visuals like people knocking down walls, rushing into the streets or standing in lines. The Fall of the Berlin Wall is the Fall of Communism, the fall of Saddam's statue -- now these are stories of new freedoms. In America today, we have a big fall without a distinctive symbol, without a video loop, without an exotic locale.
Also, how do you explain that China is providing the bail for the bailout? As David Gergen said tonight on CNN, "China's become our banker." Even harder to tell that kind of "freedom" story.
9) The problems aren't going away and there's no timeline. So, where's the equivalent of "America Held Hostage: Day XN"? Nightline evolved from a special report to become a nightly hard-news program to follow the ongoing story of Iran holding American hostages during the Carter Administration. Why isn't this economic story played front-and-center in the same way? Isn't there a TV journalist saying "Holy Christ, this is the biggest story of my career and I'm going to bring it to you every night"? Ted Koppel, Edward R. Murrow, where are you?
Here's my list of names for a new Nightline-like special series on the economy:
10) Lastly, the TV media is no better off than we are at understanding this complex crisis. On a gut level, viewers know what the story is, that it's about them, their future and their children's future. They have specific questions that are difficult to answer (see the Suze Orman blog on CNN where it is promised that she'll answer these many, many questions; she doesn't, of course.) and they have general worries (should I panic?) that are hard to resolve. While we try to absorb as much information as possible, we keep having the same conversation over and over:
Q. What's going on?
A. I don't know. It's hard to tell.

Here's a neat opportunity for you music makers out there, the Guthman Musical Instrument Competition by Georgia Tech, Wired, and Harmonix (the makers of Rock Band):
INSTRUMENTS
Any new musical instrument is eligible for the competition. Instruments may generate sound acoustically or electronically, they may exist in physical or virtual manifestations, and they may be played by humans, robots, or computers. They may modify, improve, or extend existing instruments -- including the human voice -- or they may offer entirely new design paradigms. New instruments which cross over these categories or which defy any such categorization are also welcome.
PERFORMANCE
Entrants must perform a musical work with their new instrument to demonstrate its musicality, design, and engineering features. Performances may include traditional acoustic and/or electronic instruments alongside the new instrument. They may also include multimedia elements such as video, animation, graphics, text, kinesthetics, hydraulics, dance, or acting. The performed work may be composed by anyone, including the entrant, or it may be an arrangement of an existing work. It may be in any musical style. The duration should be between 2 and 10 minutes. Entrants must be prepared to perform with their instrument at Georgia Tech on February 27th-28th, 2009.

Zhibin Zhang of the Chinese Academy of Sciences and colleagues have trawled through 1000 years of historical records documenting locust swarms and compared it with 1000 years of temperature, drought and flood data estimates.That doesn't mean swarms won't happen. (Add this back to the list of things to worry about.) This month in Australia, drought followed by heavy rains in New South Wales has brought enormous swarms of locusts. One swarm is six kilometres long and 170 meters wide.
image from wikipedia.They found that the Oriental migratory locust (Locusta migratoria manilensis), which has been named as one of the most damaging agricultural pests in Chinese history, operates on a climate-driven cycle. Every 160 to 170 years, the swarms get bigger then subside again.
Counterintuitively, the timing of the largest swarms coincides with cooler periods.
"The popular view is that global warming may accelerate natural and biological disasters like drought and flood events, and outbreaks of pests, as predicted by the IPCC," says Zhang. "Our results suggest that warming reduced climatic extremes and locust plagues in ancient China."
Here's a BBC video of the swarms. It's kind of like watching Hitchcock's "The Birds".

Today on Offworld we discovered that the post-apocalyptic Wasteland in Bethesda's RPG Fallout 3 was about to get a little bit wider, got a glimpse of what a Criterion Collection for games might look like (props for the analogy, N'Gai!), and learned that -- happily -- the world's Guitar Heroes are picking up real guitars as well.
We also looked at a photojournalist's project that shows us what it looks like when we're immersed in our virtual worlds, read about the people who got rich off those worlds, and listened to me live on national radio trying to explain the importance of those worlds.

While filming the Wii/Arduino Flight Recorder episode of Make: television, we went to the Mall of America for a location shoot. The Mall has four roller coasters in it. How many does yours have? Mine has none, but I think that's because it never gets cold in Los Angeles, so we leave ours outside.
We were there to film me pulling low-grade g-forces on the turns and hills. I don't like huge coasters (OK, I'm a total wimp) but they assured me it would be a dinky little one. I arrived with the executive producer and the rest of the crew were already there, standing in front of a coaster with big vertical drops, loops, corkscrews, the works. I'm starting to feel a bit uneasy (read: terrified) as they're figuring out how to get a camera man, sound guy and me on this thing and film the segment while we're all white-knuckling it and screaming our innards out.
Thankfully, we all decided (I begged) it was going to be too violent a ride for us and we downgraded to a happy little regular coaster for lightweights like me. The slap in the face: all of the teenage girl extras went on the scary one anyway just for fun.

Fuya
The best thing about the fuya is that it can be sliced and eaten like an apple or not-quite-ripe pear. You don't need to peel fuyas. My favorite use for fuyas is sliced or diced in salads. Last Thanksgiving, I created a relish with diced fuya persimmons and pomegranate seeds mixed together.
Hachiya
The hachiya persimmon is more familiar to people, and the trees are also more commonly planted. Hachiya need to be very ripe before using. Putting them in a bag helps to force ripening.
Hachiya persimmons are very astringent - your mouth will be unusable after taking a bite. Just don't eat them off the tree, like a fuya. Typically, this kind of persimmon is turned into pulp and then used to make a sweet bread or a pudding. I saw a recipe for a persimmon sorbet, which I'll have to try, maybe for the Christmas holidays.
In short, you can't have enough fuyas but you'll easily have too many hachiyas.

James Delaney's created The Unfocused Brain, an interesting variation on Mitch Altman's Brain Machine:
This program and schematic is designed to flash LED's in certain brain wave inducing patterns. The device is controlled by four buttons that switch the generator between Alpha, Beta, Delta, and Theta frequencies....
After building and trying out the SLM I noticed that certain transitions from one state to another created particularly strong visual hallucinations.
My project is a deviation from the original SLM. Since my hallucinations seemed to be the same with or without the audio component I decided to leave it out. I added buttons rather than a program so the user can change frequencies spontaneously. I built this project with the Attiny461 chip.
Check out the Make Brain Machine thread for more ideas on variations.
And, if you get really ambitious, switch to low-frequency ultrasound for brain stimulation (pdf; thanks to Bryan Bishop for the link)
