I'm delighted to introduce a new occasional guest blogger on Boing Boing, Dr. Jacques Vallee, who will contribute posts every so often. In the world of computer science, Jacques is best known for his pioneering database research in the 1960s at Stanford Research Institute and then, during the next decade, for leading the development of the the world's first network-based computer conferencing system for the ARPANET. He launched that project, called PLANET, in 1972 at Institute for the Future (IFTF), the non-profit thinktank where I'm a researcher. At IFTF, Jacques and his colleagues studied the social impact of online communication and explored its applications in industry. In 1976, Jacques founded InfoMedia, the first computer conferencing and groupware company. I met Jacques in person several years ago when he popped into IFTF for a visit. It was quite exciting for me as I was quite familiar with his work, albeit in a very, very different context.
For nearly fifty years, Jacques has studied the history and culture of the UFO phenomena and written a slew of fantastic books on the subject, always calling for a scientific investigation of reports rather than an approach rooted in belief. Among ufologists, Jacques is very much a "heretic among heretics" for opposing the typical opinion that UFOs are nuts-and-bolts spaceships piloted by extraterrestrials. Jacques once said, "I'll be disappointed if (UFOs) turn out to be only spacecraft from outer space." Whenever I see the movie Close Encounters of the Third Kind, I get a kick out of François Truffaut's character Claude Lacombe insisting that the UFO phenomenon "is an event sociologique!" That is exactly something Jacques would say, and indeed Steven Spielberg based the character on him. My favorites of Jacques' books are Passport to Magonia: From Folklore to Flying Saucers, Messengers of Deception, and The Invisible College, where he considers whether we're living inside an information-based control system, a mind-spinning idea that's now embraced by many physicists.
Recently, Jacques published the second volume of his personal journals, titled Forbidden Science, and is now completing a new book about ancient UFO sightings. He also works as a partner in a venture capital firm investing in emerging technologies with potential space applications. Jacques's intellectual rigor around anomalous phenomena and weird science has inspired me since I was a teenager. I'm thrilled to have his voice on Boing Boing.

Ralph Baer and His All-Purpose Boxes
Two workers at a Lexington, Kentucky public library were fired after it was discovered that they had teamed up to keep a copy of Alan Moore's The League of Extraordinary Gentlemen: The Black Dossier out of circulation.
According to the story, Sharon Cook, 57 and Barbara Boisvert, 62, basically colluded to keep the book out of circulation -- Cook, who had become disturbed by the book's imagery, checked it out for a year, meaning no one else could check it out. However, when an 11-year-old girl put it on hold, Cook was unable to continue her delaying tactic -- and Boisvert stepped in, removing the hold, and keeping the book out of circulation.Alan Moore, destroyer of library workersBoth were fired for their actions. The Jessamine County Public Library has not commented on what they call a personnel matter.
Cook seems to have some kind of obsession with the book -- she's still carrying it around in her knapsack, the dirty parts marked with Post-Its. This, despite what she describes as her mortal danger when reading the book:?
"People prayed over me while I was reading it because I did not want those images in my head," she says.

Among the hairier of my hare-brained schemes involves formulating a safe-to-drink chemiluminescent cocktail. I think the first person to do it will become a very wealthy laughingstock, which, as I understand it, is the very definition of The American Dream.
So I got really excited when I first saw this post over on TheDieline.com, because I thought somebody had pulled it off. Unfortunately, it's just the labels that are glowing, not the booze itself, but still it's pretty cool. If you ignore the crass commercialism, the shameless marketing, the horrors of alcoholism, drunk driving, etc., etc. [via Geekologie]

Barring any major uptick in stupid, this will be the last time I poke the 2012 believers with a stick. I swear. (At least, until January 2013.) Besides, this is a slightly different take than the usual debunking. The Santa Fe Reporter (the paper) sent Santa Fe reporter (the person) Corey Pein into the heart of the End of the World Industrial Complex to capture a slice-of-life that is by turns frustrating, fascinating, depressing and hilarious.
To be precise, there are 1,149 days until Dec. 21, 2012, when something will--nay, must--happen. It won't be the end of the world but, if it is, SFR regrets the error.
And later,
One nine-part YouTube film claims "The Illuminati Freemasons" have conspired over centuries to erect the new tower of Babel, aka the Freedom Tower, over the World Trade Center site in 2012. ("Anti-Semitism tends to float behind some of the conspiracy theories," Hoopes says.) The sublimely paranoid film also claims that since the 1970s, this cabal has "conveniently conditioned you to accept that global warming is all your fault," when actually "Your SUV's have little to do with it.. THEY.. conditioned you to become AFRAID of the SUN and CO2." Another production--by a man whose résumé boasts a few years' work long ago as a CNN field producer--makes the exact opposite argument, assailing "global warming deniers" for hiding evidence of the coming catastrophe. "In 2012, Americans will be burying their dead as their forefathers did during the Civil War--by the thousands. By the tens of thousands," the narrator says solemnly. (He goes on to pitch a "2012 Survival Guide," $34.90 plus shipping.)

The owner of this electric shaver with a faulty power switch taught it a lesson it won't forget. I think it's great that he fixed it instead of throwing it away and buying a new one.
Any hams out there that need a quick-and-dirty morse code beacon? Then you might be interested in Mark VandeWettering's Arduino Based Morse Beacon. I really like the clever way that he stores the code sequences for each character:
It's a little bit clever (a very little bit) but I guess it does require some explanation. Morse code characters are all length six or less, and each element is either a dot or a dash, so it would seem that we can store the pattern in six bits. Let's say that dits are zero and dahs are one. Lets store them so the first element gets stored in the least significant bit, and the next in the second most, and so on. The only trick is knowing when there are no elements left, because otherwise we can't tell (for example) K (-.-) from C (-.-.) To do that, we store a single extra one after all the other elements are taken care of. Then, when we are looping, we do the following. If the pattern is equal to one, we are done (that's our guard bit). If not, we look at the least significant digit. If it is a zero, we have a dit, if we have a one, it's a dah. We then get rid of that element (by dividing by two, or shifting right if that floats your boat) and repeat. Voila. Each character takes only a single byte to store its pattern, and decoding is just done in a few instructions.
Mark admits that using an Arduino for this is a bit of overkill, however I think that convenience trumps component cost for one-of projects like this. If you are up for the challenge, however, you could probably build one with more esoteric components, such as an EEPROM+counter, or even a music-box type mechanical system. Anyone create something crazy cool like that?

From $50 bamboo T-shirts to environmental coloring books handed out by petroleum companies, greenwashing continues to be high on my list of "Things That Make Me Want To Rip My Hair Out and Then Go Do Worse to the People Responsible." The worst part, of course, is that it's often not easy to know when your green is coming to you heavily laundered. ClimateCount is an organization that's trying to help on that front. They put together an annual scorecard of Fortune 500 companies that breaks down these firms' real record on the environment. Then they rate the company's commitment to environmental responsibility as Stuck, Starting, or Striding. Everything is separated out by sector, so you can easily find the companies you want to check up on. Granted, I'm not convinced that Airlines, as a category, are ever going to move much beyond Starting. But I'm also frankly impressed that any are even at that point. So, tradeoffs.
Couple of major downsides. First, this list is by no means comprehensive. We're talking Fortune 500 here, so that won't help you if you don't do a lot of business with those companies to begin with. For instance, the Beer category is sadly limited to Anheuser-Busch, Molson Coors, and SAB Miller. And what a cold, sad world that would be.
Second, this is all a little subjective. Proctor and Gamble may get a Striding rating, largely for setting up energy use reduction goals that produced some results, and that may make them more green than their competitors. But does that really make them a green company? Overall, I think this might be better for helping you figure out which companies are totally blowing smoke up your various orifices than it is at helping you know which companies are truly awesome. But even that is useful.

I'm also taken aback by the horrified response of the book industry. I thought the big crisis was that nobody reads. Now it turns out the problem is that books are so popular with the masses they're being used as bait to draw in shoppers.But most of her brilliant sarcasm is directed at those in her own profession, who both work hard to get information for free, at the same time they complain about how the internet has made it so easy to route around librarians:
Come on, guys, get your story straight! Which is it?
It strikes me that this issue is somewhat parallel to the love-hate relationship that many academic librarians have had with the Internet. Although our complicated relationship is improving, there are still some silly assumptions floating around. Oh no, our reference stats are down! Hurrah! People are able to find answers without our help. That's awesome! Anybody can publish on the web, unlike scholarly journals which are peer-reviewed. Fine, but don't tell me all peer-reviewed journal articles are shining examples of reason and academic brilliance. A lot of them are finely-sliced research rehashing the same findings, or are closely examined and exquisitely detailed trivia. Besides, there are plenty of examples of peer review failing in spectacular ways--and examples of wonderful peer-reviewed journals that were born free online.It's a great overall column, and nice to see a librarian lay the smackdown on hypocrisy within the bookselling and librarian worlds.
But this is my favorite: Unlike information you find on the web, we pay for the information in our databases, and you get what you pay for. No, actually, with what you pay for you get a lot of junk that you don't even want, but you have no choice.
You want this journal? You have to subscribe to this pricey bundle. Either that, or you purchase one article at a time for your users, something more and more libraries are doing. You spend less, but the information never visits the library--it goes straight from the publisher to the desk of one user. All the library gets is the bill. Apart from failing on its merits, the argument that paid is better than free is self-contradicting. We can't tell students that purchased information is by definition better than free and, at the same time, beg faculty to recognize how broken the current system is and please, please, please make their work open access.
When it was revealed that the U.S. resorted to torture to extract information from prisoners, many people my age must have had a very somber thought for the thousands of young Americans who had given their lives on the beaches of Normandy in a brave effort to rid the world of governments that engaged in such shameful practices. Two other thoughts flashed to mind: the stupidity of giving up the high moral ground at a time when the U.S. had earned so much goodwill thanks to its stand on democracy and human rights; and the pointlessness of such interrogations, often stated by our military experts, since the victims will generally admit to anything in order to stop the pain.
My friend, French Résistance leader Jacques Bergier, who was tortured multiple times by the Gestapo, made the ludicrous "confession" that his network planned to invade Corsica. In reality they were looking for heavy water and for Werner von Braun's rocket base.
As a child of World War Two who remembers its limitless horrors, my revulsion at the practices of Guantanamo and Abu Ghraib was so great that it took me a while to realize the more positive implications: if our henchmen used waterboarding, a practice so primitive it placed us in the same hateful historical imagery as the caves of the Inquisition and the cellars of the Nazi, this can only mean that all the fancy interrogation drugs developed in classified labs in the 60s and 70s have failed: there is no truth serum. We should be relieved about that.

We already knew that LSD, once hyped as the ultimate key to the mind, did little more than propel you into colorful delusions. But evil doctors had other tricks and claimed to be working in secret on even better, kinder biotech ways to crack open the human soul and read it like a book. Using everything from neurotoxin derivatives to functional MRIs, the State would soon overcome personality defenses, in the interest of our collective safety. It would finally control not only our deeds but our thoughts as well, thus achieving law and order on a grand scale.
Evidently the scheme hasn't quite worked out as predicted: If we could simply slip a little green pill to the bad guys to find out their plans, we wouldn't have to resort to messy medieval practices that don't work. So let's go back to the legal methods of interrogation recommended by the professionals. And let's thank waterboarding for the realization that our intimate thoughts, prayers and dreams, flaky though they may be, will remain safe from chemical violation a little while longer.

From Seth Roberts' Blog:
One of the last things Jane Jacobs wrote was a friend-of-the-court letter in the Supreme Court case Kelo v. New London where eminent domain was used to take property from private landowners and give it to a private corporation (Pfizer). It was just as outrageous as that sounds. And Pfizer got away with it.

Businesses dependent upon exceptions to copyright contribute $2.2 trillion to the U.S. economy. They are responsible for one in eight jobs, for a total payroll of $1.2 trillion in 2006. Fair use is serious business; it is the glue that holds the Internet and new technology together. It is worth protecting.This is fantastic. Of course, the number is just as bogus as the $1.52 trillion used by copyright maximalists, but I think that if they're going to use their methodology to make such ridiculous claims, it's only fair to do the same for the contributions to the economy of exceptions to fair use, and as the CCIA clearly demonstrates, the businesses that rely on weaker copyright contribute significantly more to the economy than those that rely on copyright. Thus, by the copyright maximalists own logic (and numbers), shouldn't we be fighting to expand the exceptions to copyright law?

You might have just driven home. When you filled your car with gasoline, most likely you didn't even see the fluid as it was pumped into your gas tank. Once home, you probably turned on some lights, some music, your computer, and maybe even heat, so you could read this web page. You can't see the power running through the electrical lines that lead to your light bulb, and you don't feel it, but you do enjoy the results. Our society has made energy invisible. This invisibility makes energy convenient to use -- and the modern age is arguably wonderful as a result -- but it also makes it easy to take it for granted. Here we try to make our appetite for energy visible.
Climate change is a phenomenon we now recognize as one of the most important challenges to ever confront humanity. Like energy use, it is also mostly invisible to us, and in two important ways. Firstly, the enormous volumes of green-house gases -- carbon dioxide, methane, CFC's etc, are quite literally invisible to our naked eyes. Secondly, the changes in climate progress so slowly that they seem invisible amidst the hustle and bustle of our daily lives. Because these consequences accumulate over decades, generations, and centuries, it is easy to not see them as pressing and urgent. Here we try to make visible these complicated and largely invisible things.
The global energy and climate conversation is about choices, both individual choices and collective choices. By choosing the amount and type of energy we consume, we are choosing the look and feel of our future. Everyone is involved in that choice. Don't be fooled: individual choices collectively have enormous effects. A large coal power plant has a power output of 1GW (GigaWatt) which is 1 billion (1 000 000 000) Watts. If 1 billion people reduced their power needs by just 1 watt ( About what is required to keep a compact fluorescent burning for just 1 hour a day), that's a coal fired power plant you don't need to build.
This material tries to help you make those choices in a more informed manner. We also hope this material influences the governments, organizations and corporations who make the decisions about our energy future on a macro level.
These posts are about energy, climate change, finite resources, and the future. Unfortunately, the creation of this material is implicated in the very climate change and energy challenges we wish to avoid. You chose to read this, which means you chose to use some energy. These posts are not "carbon free" or "carbon neutral". At the time of its publishing there was practically no way that it ever could have been. Nearly every choice you make involves energy and all those choices have implications for the environment.
Two people wrote this stuff. We both ate food produced by modern industrial agriculture to power ourselves while writing. We used at least five computers at different times to do the calculations, write the words, and edit the layout. After we had done our work, editors and designers used computers to further refine the text and images. Each of those computers ran for many hours, consuming somewhere between 20 and 200 watts of power each as they did so. The computers themselves were made in factories in China and Japan with chips produced in the United States, and cases probably made from bauxite mined in Australia and processed in Argentina.
If you print this out, the paper it is printed on was probably made from trees that were cut down in Canada. The chainsaws that cut the trees ran on two-stroke gasoline. The trees were lifted onto a truck with a crane powered by diesel fuel. The truck drove the trees to the sawmill using diesel. Before the trees from which these pages were made had even been pulped, three internal combustion engines had been fired up, burned a fossil fuel and emitted some carbon dioxide. How much CO2? Not a lot. But all the little pieces add up.
If you are just reading this on the web, there are disks and processors in data centers in numerous places running from coal plants, gas plants, even hydro and solar plants where the production of the cement and silicon was itself done using fossil fuels. The point is, it's a really complex system.
As these paragraphs show, the global supply chain for energy is complex. This was in small part inspired by the pamphlet "I, Pencil - My Family Tree as told to Leonard E. Read." (1958). A piece that highlights just how interconnected our modern world is.

We fill our cars with gas regularly, but don't even see the liquid go into the tank. If we were to imagine that we had to fill a backpack with the fuels required for a day of our lives, what would we be filling our energy back-pack with each day?
Each day the average American sets out with:
OIL = 10.81 L/Person/day (2.9Gallons)?
COAL = 9.54 kg/person/day (21 pounds)?
NATURAL GAS = 5.88 m^3/person/day (208 cubic feet)
Which roughly converted to those other units is around 22 Pints of oil per day (one per hour!), 21 pounds of coal (another per hour) and 200 cubic feet of natural gas.
I used the annual consumption of coal and natural gas, and the daily consumption of oil, and converted it to the daily average by dividing it out by the population of the US.
The data is here.

Got a pedal-powered TV, but still have to keep replacing the batteries in that remote? Then you might want to keep an eye on this piezoelectricity batteryless remote (machine translation), being developed by NEC and Soundpower. Energy harvesting devices are nothing new, but this one seems interesting because it is apparently efficient enough to work off of the vibrations caused by pressing the buttons on it. They claim that it uses piezoelectric elements, which can generate electric current when bent or deformed, to capture the kinetic energy of your button press.
Of course, if you don't have access to fancy piezoelectric development tools or want to wait for their device to come out, you could probably whip up something similar by combining one of those shake flashlights and a regular remote. Anyone try that yet? [via technabob]

I'll give you a hint: It has absolutely nothing to do with Star Trek, Star Wars or Dr. Who. (To my knowledge. Fanboy schooling commences anon.)
More commonly called Freeth's Nephroid (which makes it sound less like a tentacled devourer of souls and more like a little boy's pet monster), it's actually a special plane curve--which is also not as weird and confusing as it sounds. Yeah, we're talkin' about a math thing today. (This was always my "B" subject, so feel free to let me know if I'm being wrong on the Internet. Again, fanboy schooling commences anon.) Onward to knowledge...

Plane curves are really just curved shapes that exist in a two-dimensional, as opposed to three-dimensional, space. Think circle vs. sphere. "Special" plane curves are the ones that turned out to be interesting enough that mathematicians gave them their own name. Our friend the circle is a special plane curve. Ditto the parabola (aka, the curve that's kind of shaped like a boob). And, because this is math and they just like to mess with you by making "curve" not mean what you think it means, so is the line. Yeah, the "line" is really a specific thing that the general public uses as a generic term. Like kleenex.
But back to the Nephroid of Freeth. Now we know what this thing is, in general. But why is it interesting? And what's with the name? For my own sake, I'm starting with the easy question.
Nephroids are special plane curves that are shaped sort of like kidneys. (Not has fun of an analogy as the parabola, but hey, I didn't make this one up.) They often have the appearance of something produced by a bunch of mathematicians playing with a Spiro-graph. Technically, though, the shape has to do with with the way rays of light reflect off a semicircle.
The classic example is the pattern of shadows that you see at the bottom of a coffee cup when it's set out in the sun. Light reflects off the semicircular sides of the cup and you see nephroids on the bottom.
Freeth is a dude. Rather, was. Specifically, one T.J. Freeth, an English mathematician who died in 1904. He was pretty into strophoids, plane curves that are shaped like "a belt with a twist." They are all fancy like that.
Strophoids are curves, but they're also things that happen to curves. Plane curves that get their panties in a bunch, if you will. So that image above is the strophoid of a line. Freeth's Nephroid, on the other hand, is the strophoid of a circle.
See how that works?
Yes, of course you do. But you're still wondering why you care. On a practical level, I'm told that you can use the Nephroid of Freeth as a jumping off point to drawing seven-, 21-, 35-, etc.-sided shapes inside a circle. Which is great, the next time you need to do that. However, astronomer David Darling has a more practical suggestion, writing that the Nephroid of Freeth "has been described as the perfect shape for a multi-seat dining table." I'm assuming he means the kidney shape with the strophoids becoming a cutout on one side, in which case, I'd be inclined to agree.
It's also the name of a pub quiz team made up mostly of mathematicians from the University of London.

Every other week, MAKE's awesome interns tell about the projects they're building in the Make: Labs, the trouble they've gotten into, and what they'll make next.
By Steven Lemos, engineering intern
Making the Hydrogen-Oxygen Bottle Rocket (that Adam Savage is posing with on the cover of the new MAKE, Volume 20) was a pretty basic endeavor, with the exception of the circuit. The original schematic diagram had a flaw in it, but only after we breadboarded the circuit -- twice -- did we catch it.
I guess that's the reason we MAKE interns build the projects that run in the magazine, so it's us who bang our heads against the table and not you. I will kindly take that cookie now.
The experience showed me that, sure, when working with electronics it's easy to misplace a component or wire, or completely miss something, which I already knew, but it's just as easy to have a diagram be the culprit. So a word to the wise (a word I'm sure all the experienced hobbyists have already discovered for themselves): if you take care when putting together these tedious circuits it will pay off, for if you can trust in your work, then you'll know the culprit lies in the plans, and you won't spend hours chasing that metaphorical wild goose.
![]()
Twice we breadboarded this bad boy before discovering an error in the schematic -- so you won''t have to.
But on to the actual launch. :) We had talked to the local electronics store owner, who at the time was making his own hydrogen using a more sophisticated apparatus, and who was interested in what we were doing with ours. So he came to watch, and brought along his professional pyrotechnician friend, who showed us how to make fuses with 12V and tiny resistors (basically the resistors pass so much current that the wire heats up and can act as a fuse to light stuff -- voilà, cheap fuses).
![]()
Our beautiful 2-stage HHO rocket ready for test launching -- before being crippled by a crash.
The first launch was a success, with the two stages going off rather quickly in succession, so we dialed in a little more delay time in the circuit before the stage 2 ignition. This was good and bad. We got more height out of the rocket on our second launch, but on its return it landed electronics side down. This resulted in our circuit behaving oddly.
So, not ready yet to call it a day, we began firing off only one stage at a time, adjusting the proportions of HHO (hydrogen and oxygen gases), water, and air, and testing the makeshift fuses, which worked fine for a single stage, but due to the time they take to ignite (3sec@12V) might not work for 2 stages.
We probably launched 12 times that day, attracting passersby. Good weather, new friends (who like blowing stuff up), and multiple launches. All in all, a good day. Houston, we have liftoff.

As the holidays approach this year, money is tighter than ever for everyone. When thinking about gifts to give, consider the gift of DIY electronics and kits, not only could a loved one learn a new skill, but it could start them on a journey to a wonderful lifetime hobby, possibly a career! Helping someone learn electronics is more than just giving a circuit board and a bunch of parts, you're giving the gift of time, hours of new experiences exploring the wonders of engineering and science. In the end, they'll also have something to show and share!
So let's get started. I've put together my 20 favorite (mostly) under $20 electronic kits and resources, some are from the Maker Shed, some are from other places (SparkFun, Adafruit, Instructables, TechShop, Solarbotics, Evil Mad Scientist Laboratories, Parallax). Many of them are open source hardware projects, so if $20 is still too much, you might be able to put these together on your own and print out the instructions for free too! Our gift guides are meant to inspire your suggestions, so if you know of a great $20 or under electronics kit, post it in the comments!

Living in the UK, Jim hadn't experienced an earthquake firsthand. After watching recent quakes unfold in Indonesia, he decided to create a device that would keep him aware of the Earth's seismic events. His Seismic Reflector uses a Processing-based software monitor which feeds data to very motorized Arduino -
The aim is to build a device which responds to earthquakes being reported in near-real time via the USGS RSS feeds. The device responds by illustrating the magnitude of the reported earthquake via two fairly chunky vibration motors of the kind used in video game controllers. The device is connected to a PC via a virtual com port over USB (thanks to an on board Arduino). On the PC, an application sits there checking the RSS feed periodically and when a new event it posted to the RSS feed, the desktop app parses the data out of it and presents the magnitude of the quake to the Arduino which interpreters this as rate at which to activate the vibration motors.Check out the Seismic Reflector instructable for details.

I'd just like to stress that this project is about empathising in some small way with victims of earthquakes. I'm not trying to make light of peoples anguish or suffering, and I'm not trying to play on peoples fears of an impending "big one". I do not experience many earthquakes where I live, but I know a lot of people around the world (specifically around the Med and the Pacific) do. This is my attempt to understand that feeling a bit better.

Fresh out of 8-pin DIP sockets, I broke off a couple rows of female machine pin headers as a substitute - using the chip itself to align the pins for soldering. That was about a month ago, and I've continued using them ever since. Though it seemed a bit 'kludgey' at first, this process has proven a lot easier than trying to keep a variety of socket sizes at the ready. As always, your mileage may vary.

If San Francisco City Attorney Dennis Herrera gets his way a generation of club goers will miss out on the sickly sweet tang of caffeinated alcohol beverages like Sparks, Four-Loko, and Joose. Yet, all is not lost. A group of enterprising practitioners have seized the opportunity to handcraft a batch of Bathtub Sparks in an attempt to recreate the extreme libation.
The following drink was reverse-engineered from a vintage can of caffeinated Sparks and rigorously tested via blind taste-test by SFoodie and four people who agreed to come over to the author's house and drink this stuff, plus two random guys on the street who should be applauded for their daring and general zest for life.

Banned Xboxs flood online marketplaces via BBG.
Hundreds of Xboxs have appeared on online marketplaces such as eBay and Craigslist in the wake of the mass Xbox live bans. Over the past week Microsoft has banned nearly one million users from the online gaming service after finding that they had modified their consoles to play pirated games. Since the ban is connected to the console rather than a gamer's online account, many modified Xboxs have appeared online being sold by banned users. eBay has issued a warning to users on its website to be wary of buying consoles in the wake of Microsoft's move. In a post on the website's guide section, it said: 'If you are looking to buy an Xbox 360 on eBay in the near future, ask the seller if it has been banned from Xbox Live and be sure to pay by PayPal in case they lie. If you do get a banned console, start a PayPal claim.'Microsoft has said that all bans are permanent to the console and no affected units will be permitted back onto Xbox Live on any account.
You can get a banned console for $40 now. I know that a lot of Microsoft folks read MAKE so please Microsoft folks, figure out something else besides permanently crippling millions of devices. Sure they can be used to play offline, but I doubt the owners will keep them, so it's one stop to trashville. They'll end up in a landfill, at least offer a way to re-active them or something, anything.
Casio has unveiled the world's slimmest 'rugged' compact in the shape of Exliim EX-G1 - its thinnest side measures just 20mm (0.78"). The first in the company's new 'Exilim G' series of weatherproof cameras, named in reference to the company's well-known G-Shock series of watches. The G1 is designed to be dustproof, waterproof up to 3 meters for an hour, coldproof up to 14 °F and shock-resistant for drops of up to 2.13 meters. It incorporates a 38-114mm equivalent lens, 2.5" LCD, 12.1MP sensor and includes features such as Intelligent AF, Best Shot shooting mode and Interval shooting. Priced at $299, the camera will start shipping from December 2009. Comments Off [link]


Jim did some experimenting with homemade thin-film zinc oxide and zinc-tin oxide, developing his own homemade transistors devices -
I did manage to achieve (with a liquid dielectric) voltage and current gain, as well as construct a functional astable oscillator using two of the devices constructed on a single substrate. While the speed of the devices (due to the liquid dielectric) is such that they are only interesting as a technology experiment, they've been a lot of fun to experiment with.Some very interesting work here. There's really no better way to understand technology than to build it yourself. I can say firsthand, building a simple capacitor or LED from scratch is a lot of fun - a DIY transistor must feel like a straight-up triumph! Download the documentation of Jim's experiments in PDF format on his site.

Jenny tasted the power of bhaiya while watching friends negotiate with autos, seeing housewives beat down stubborn vegetable wallas, observing clever coworkers convincing recalcitrant art directors to meet impossible deadlines. A woman takes a simple bhaiya--"buy-yaa", to transliterate--and bends the word around the fulcrum of the "y", modulating the final syllable to do her dastardly bidding.on Hindi: the power of "bhaiya" (Thanks, Dave!)Making that final syllable short and sharp expresses contempt ("Who do you think I am to quote me such a price?").
Adding a long, upward-fluctuating suffix feigns shock ("You would take such advantage of the sweet, innocent girl standing so humbly before you?").
And turning that final syllable into an angry cadenza up and down three different octaves--think John Coltrane at the end of Giant Steps, an animal howl, the fire in her belly that would have singed the quivering beedi right out of the hapless auto driver's mouth if she hadn't stuck a bhaiya in front of it--chastens even the most determined male foe...

With this award-winning Robotic arm kit, you can control the gripper, wrist, elbow, base rotation and motion, all from the tethered remote. The robotic arm has a vertical reach of 15", horizontal reach of 12.6", and lifting capacity of 100g. Features include a searchlight on the gripper and an audible indicator on all 5 gearboxes to prevent any potential injury or gear breakage during operation. Who is going to be the first to hack this with an Arduino?

We love bikes, just check out all our bicycle related entries. Unfortunately, sometimes our bikes break, and when they do it's a lot easier to repair them if you have a stand. Too expensive? Then make you own bicycle repair stand with a few parts form the hardware store.
I've needed a repair stand for a long long long time now. But....damn those things aren't cheap. Thankfully, I've got more than my share of blue collar blood in me....so I decided to build one. The process couldn't have been easier. I did a quickle google search on home made repair stands and saw some interesting solutions. In the end, I went with my own variation.Read more | Permalink | Comments | Read more articles in Bicycles | Digg this!

Artist Shepard Fairey and photographer Glen E. Friedman collaborated on the image above, adapted from a photograph Friedman took of legendary skateboarder Jim Muir. The poster goes on sale for $80 on November 19, in a limited edition of 450, signed and numbered by the artists and by Muir. A portion of proceeds will be used to pay Muir's medical bills -- he was badly injured in a surfing accident earlier this year.

Here's a mid-1980s CBC News scare-story about Dungeons and Dragons driving kids to suicide featuring (at 2:49 onwards) me and my classmates (the video is dated 1985, but I'm pretty sure this couldn't have been later than my graduation from Junior High in 1984). Ignoring the crazy-ass fearmongering, it's incredibly nostalgic to see all those kids I grew up with, playing with their minis and rolling their dice.

Spotted in the MAKE Flickr pool:
ITP students Hana, Ania, and Greg built this augmented xylophone, the multixylophoniomnibus. Despite having a basically unpronounceable name, the project looks nice and they have a very in-depth review of the process that they went through in order to produce a working product. Nice job!
They also have a large number of photos available in their Flickr photo set.

It's the McLVDT, a linear variable differential transfomer, made from McDonald's straws. The creator writes:
I made a primary coil on a normal sized straw, and made two secondary coils on the outside of the larger McDonald's straw. Since the McStraw is large-bore (perfect for those thick high calorie shakes), the smaller straw with the primary winding fits nicely inside. The position of the inner straw can be determined by examining the amplitude and phase of the combined signals of the secondary coils, which is shown in raw form on the oscilloscope.Read more | Permalink | Comments | Read more articles in Electronics | Digg this!
