DIY High-Speed Book Scanner from Trash and Cheap CamerasDigital books change the landscape . After suffering through scanning many of my old, rare, and government issue books, I decided to create a book scanner that anybody could make, for around $300. And that's what this instructable is all about. A greener future with more books rather than fewer books. More access to information, rather than less access to information. And maybe, years from now, a reformed publishing/distribution model (but I'm not holding my breath...).
I've built two of these things now, and this instructable covers the best parts of both of them. You can build a book scanner using only hand tools plus a drill. I realized that not everyone is comfortable with using all the different hand tools you might need to make it. So I scanned a book on using hand tools that should answer all your questions. ;)

Wouldn't that be nice. Wouldn't it be nice if metropolitan newspapers didn't have to pay millions of dollars a year for their reporting staffs? Wouldn't it be nice if Keller's paper didn't have to pay $2 million a year to maintain its Baghdad bureau? Newspapers provide an expensive product. They deserve to be paid for it.We've debunked this argument probably 50 times in the last year alone, but since Brinkley apparently doesn't do any research, let's debunk it one more time. No one is saying that because information is offered to consumers for free that it means that you don't make money or you don't pay your reporting staff. Brinkley is setting up a bogus strawman (the sort of thing reporters shouldn't do). What they are saying is that they need to come up with better business models (which we've pointed out do exist) that leverage (rather than deny) the basic economics of content, and do so in a way that makes a more valuable product.

Recently on Boing Boing Video: bacon and animated childhood fantasies.
Above, we learned how to fashion a thermic lance from prosciutto, "an engineering-grade form of bacon," capable of cutting steel. Also, a vegan version of this lethal device fashioned from cucumbers and breadsticks. PopSci columnist Theo Gray invented the device, and as the YouTube editors who spotlighted this episode said, "Fire plus bacon equals delicious, delicious thermodynamics." There's more madness like this in Theo's new book, MAD SCIENCE, which I blogged about here. Original video blog post is here. You can download an MP4 here.
Also last week, we debuted another animated short from the PSST! 3 Film series -- OMAR / HOT PURSUIT / SEARCH. Like the previous shorts we've featured from PSST! project, this one's the result of a collaboration between three teams of animators. In this one: part 1, A Victorian-sepia-dream in which a child fishes for kite-creatures in the sky, and is lifted on an incredible aerial adventure. Part 2, a Google Maps bad guy car chase drama interlude, with cops and robbers. Part 3, A child creates the magical superflat universe of which he dreams. Original video blog post is here. And an MP4 Download is here.

My friends Kelly and Erik of the Homegrown Evolution blog and authors of the terrific how-to book Urban Homestead: Your Guide to Self-sufficient Living in the Heart of the City just wrote a very funny post about a plant they can't stand: the asparagus fern.
Read the entire entry, but here are a couple of good bits:
Least favorite plant: asparagus fern"When I saw a vendor at a farmer's market selling potted Asparagus setaceus, I felt like I was witnessing a crack dealer in an elementary school lunchroom."

David Byrne First Artist to Curate Stage! (Thanks, Krista!)
David Byrne has assembled a number of performers for the first artist-curated stage in the eight-year history of the Bonnaroo Music and Art Festival. On the evening of Friday, June 12 Byrne, who is performing the "Songs of David Byrne and Brian Eno," will host his recent collaborators Santigold and the Dirty Projectors, singer/songwriter and founder of Righteous Babe Records Ani DiFranco, former Polyphonic Spree member and Beggar's Banquet recording artist St. Vincent and up-and-coming multi-instrumental all-female Norwegian alt/folk band Katzenjammer."We've been interested in inviting artists to play a curatorial role in Bonnaroo for some time now," according to Bonnaroo co-founder and producer Ashley Capps. "David was the logical choice for us and we were thrilled that he agreed. His love for music of all kinds and his passion for sharing that music make him the ultimate musical guide."
Byrne adds "this was an easy one. I basically reeled off a list of what I was listening too recently or who I had seen live recently and Ashley and Co did the rest. It's not like these folks need me to introduce them to a wider audience, at least I don't think they do...I'm just thrilled they'll be added to the festival lineup"

The San Francisco Chronicle profiled Butcher last year. Butcher digs alternative power tech in general, having installed solar panels on his roof and X10 modules throughout his house for intelligent control of appliances and other devices. From the SF Chronicle:My pedal generator is in the garage, hooked up through the Trace C12 controller in my Micro Solar Energy System to a recycled battery pack from my Sparrow Electric Car. I work out in the early morning, and it's dark. It would be pointless to use as much energy to light the workout area as I generated with the workout, so I light the area with the 12 volt LED Bar Light I put together several years ago. It uses white LED's to light the workout area. They require almost no power, so virtually everything I generate ends up in the batteries.
Butcher, who lives alone after a divorce, traces his environmental leanings to the 1969 Santa Barbara oil spill, which marred miles of coastline with 200,000 gallons of crude oil. Butcher was 14 at the time and witnessed it firsthand. He built his first pedal generator when he was in his early 20s.David Butcher: Pedal Powered Generator (via BB Gadgets)
"I was always interested in alternative energy and solar in particular," he says. "I was living in Portland, Ore., where solar is not as much of an option. So I thought, 'What else could I do?'
"I'd been on a swim team for years and I was in pretty good shape, and I thought there must be a way to get some power going."
Butcher's prototype bicycle was chain-driven and featured a welded steel frame. Today's version, with its simplified drivetrain and bolted frame, can be assembled with basic hand tools.
When he took up his pedaling regimen two years ago, Butcher tipped the scales at 180 pounds. Today, at age 53, he weighs a lean 150 and possesses a pair of legs that wouldn't look out of place on the Olympic cycling squad. Butcher's pedaling has become so efficient that he has pretty much abandoned his car (electric, incidentally) in favor of bicycling, reducing his carbon footprint still further.

Short, but zippy, fact I found out this morning, while researching a piece on mosquitoes and malaria.
I've always sort of wondered what the interaction between mosquito and parasite is like. I've often seen the relationship described in a way that implies mosquitoes are ignorant of the larger human drama playing out in their digestive tract--as though they're basically just a parasite Fed-Ex. Sure, you're getting some bad news, but that's not really the mosquito's problem.
Turns out, though, there's some fairly decent evidence that, while not really being in the mortal danger we humans are, mosquitoes infected with malaria parasites aren't exactly the picture of insecty good health, either. I've spent most of the day talking to researchers at the Imperial College in London, the Johns Hopkins School of Public Health and the University of California Mosquito Research Program. They say that, while still controversial, there seem to be a least a couple of ways malaria bites the proboscis that feeds it.
First, infected female mosquitoes lay fewer eggs than their healthy sisters.
Second, it looks like infected mosquitoes might have trouble sucking blood. Gregory Lanzaro, Ph.D., director of the UC Mosquito Research Program, says there's been some research showing that malaria damages mosquito salivary glands, basically keeping the host from slurping down a full meal. Chronically un-satiated, the mosquito would end up having to bite more victims to get a proper dinner. That's good news for malaria, which needs a human habitat in order to grow up and reproduce. A mosquito that eats from more people is a mosquito that gives malaria a better chance of not ending up like a parasitic Peter Pan. Or, to look at it from our perspective, a mosquito that's carrying malaria is a mosquito that's more bitey and, thus, more likely to spread malaria to more people.
The mosquito POV? Probably a lot like being on a diet. Forever. Is it time to eat again yet?

The court stepped through the fair use analysis, dropping positive notes here (commercial uses can be fair uses), here (a use can be transformative "in function or purpose without altering or actually adding to the original work," citing Perfect 10 Inc. v. Amazon.com Inc.), and here (fact that turnitin.com used the entirety of the plaintiff's work did not preclude finding of fair use). And it turned back a lot of other, small-bore challenges to the district court's fair use finding.While O'Toole rushes through these points, they're actually pretty important, since they're quite often misunderstood by people (even copyright lawyers) who claim that commercial use isn't fair use, or that using an entire work can't be fair use or can't be transformative. In this case, the court lays out why none of that is true. When the original decision came out, I suggested that all of these points could be helpful to Google in defending its book scanning efforts, since it could make pretty much the identical arguments on all points. It's scanning was a commercial use, but transformative (it was for indexing/searching books, not reading them), it was making use of the entire work, but again, in a transformative way.

It looks like I'll be spending another couple of weeks here at Boing Boing, which certainly leaves me feeling celebratory. In honor of the boundless excitement currently coursing through my veins, I thought I'd bring you some fun facts about one of the most iconic party pics in history--Alfred Eisenstaedt's famous VJ Day kiss photo.
Who's That Girl? Nobody Knows.
On August 14, 1945, thousands of men and women flocked to New York City's Times Square to celebrate the allied victory over Japan. There was, by all accounts, a lot of semi-anonymous lip-locking going on, but it's these two people--a sailor and a nurse--who smooched at just the right moment and became larger than life.
In his autobiography, photographer Eisenstaedt writes that he followed a sailor through the crowd, watching as the man kissed just about anything that moved and wore a skirt. When the sailor hit on a nurse who was wearing a pleasantly contrasting white outfit, Eisenstaedt took the shot...but failed to get either of their names written down.
To date, more than a dozen men, and at least three women, have claimed to be the kissers. Of the men, my favorite is George Mendonca, a Rhode Island fisherman, and World War II navy recruit, who claims he grabbed the strange nurse and kissed her right in front of his girlfriend. In fact, Mendonca says his girlfriend (now his wife) is visible in the background of the shot.
The Raw Deal
Amazingly, Eisenstaedt isn't the only one to blame for the fact that we have no idea who the kissers are. Photog Victor Jorgensen actually took the same scene from a slightly different angle...and also forgot to get the subjects' names. To be fair, though, it's hard to hate on Jorgensen, as dude seriously got the shaft. Although his version was the one that ran in the next day's New York Times, Jorgensen never got the glory (or the royalty checks) that Eisenstaedt enjoyed. Why? At the time, Jorgensen was working as a military photographer and didn't own the rights to his work. In fact, that's Jorgensen's shot I've posted here. It's in the public domain. Eisenstaedt's version, significantly, is not.
Everything Looks Better With Sharp Angles
Eisenstaedt's VJ kiss photo is one of many famous pictures that artist Mike Stimpson has recreated in Lego pieces. Check out his Web site for square-shouldered, claw-handed versions of everything from the D-Day landings, to John Lennon's bed-in for peace, to the National Geographic Afghan girl.

In just two weeks, I’ll be heading west to Seattle for An Event Apart. The event, as with any AEA show, will undoubtedly rock. It’s also on the brink of being sold out, so act now if you’d like to attend. You can also save an extra $100 off the registration by using the discount code AEACEDE.
And that reminds me. If one were looking for the best coffee in Seattle, where would one go? Let the debate begin, fine folks of the Pacific Northwest.
So he's going to bring us inspiration from media, and I expect I'll do some of that too, but I think my first tale of inspiration should come from tech, and I think it's probably going to be Jon Postel and his great law that came from experience in guiding the Internet through its early days. In all of the layers we've built on top of Postel's work, we've never found a situation that wasn't covered by his law, and never really found another law to stand alongside it. Every time I think I've figured out something I want to pass on to future generations it's always turned out to be a variant of Postel's Law. That's the sign of something profound and deep, and it's simple.
One clause that I haven't seen get the attention it deserves is the provision that would require a federal license, based on criteria determined by the Secretary of Commerce, to provide cybersecurity services to any federal agency or any "information system or network" the president chooses to designate as "critical infrastructure." It's hard to overstate how bad an idea this is. Cybersecurity is a complex and fast-moving field. There's no reason to think the Department of Commerce has any special expertise in certifying security professionals. Indeed, security experts tend to be a contrarian bunch, and it seems likely that some of the best cybersecurity professionals will refuse to participate. Therefore, it's a monumentally bad idea to ban the government from soliciting security advice from people who haven't jumped through the requisite government hoops. Even worse, the proposal leaves the definition of "critical infrastructure" to the president's discretion, potentially allowing him to designate virtually any privately-owned network or server as "critical infrastructure," thereby limiting the freedom of private firms to choose cybersecurity providers.
When thinking about cyber-security, it's important to keep in mind that an open network like the Internet is never going to be perfectly secure. Providers of genuinely critical infrastructure like power grids and financial networks should avoid connecting it to the Internet at all. Moreover, the most significant security threats on the Internet, including botnets and viruses, are already illegal under federal law. If Congress is going to pass cybersecurity legislation this session (and it probably shouldn't) it should focus on providing federal law enforcement officials with the resources to enforce the cyber-security laws we already have (and getting the government's own house in order), not give the government sweeping and totally unnecessary new powers that are likely to be abused.

The print xkcd book is not being published through a traditional company but rather by breadpig -- which was created by Alexis Ohanian, one of the founders of the social-news Web site reddit. The site has sold high-concept merchandise like refrigerator magnets or T-shirts, but never a book. (Its profits go to the charity Room to Read.)"We never made any projection -- 10,000 seems like a good run," Mr. Ohanian said, adding that this lack of research "is laughable from the perspective of anyone who knows the book industry. It's what makes sense."
The book -- with the working title "xkcd," though Mr. Ohanian says it may carry a subtitle like "a book of romance, sarcasm, math and language" -- will not initially be sold in bookstores, and probably never in the big chains. Instead, it will be sold through the xkcd Web site.
Jordan Terrell sent in this link to a DHCP library he's been writing for Arduino Ethernet. It's part of a larger RFID door lock project he's working on.

I knew that the Arduino Ethernet hardware and supporting library didn't directly support getting an IP address (and other supporting information) via DHCP. I began to look around to see if someone had developed a library that would handle the DHCP handshake, and unfortunately I could find no such library - only comments of people wishing someone would develop such a library. Well, I've started just that - a DHCP library for the Arduino Ethernet shield.Read more | Permalink | Comments | Read more articles in Arduino | Digg this!

Russ built this vintage DIY beauty 25 years ago to demonstrate the abilities of a now classic/rare chip -
Handmade SN94281-based synth I made back in 1983. The device won the Grand Champion prize at the York County Science and Engineering fair --- I was 12 years old at the time. Last year at this time, I decided to restore it to working order for its 25th birthday. It is basically a "breakout box" for the Texas Instruments SN94281 Complex Sound Generator chip. All features of the chip are available as front panel knobs or multi-position switches.Those are definitely the greatest rotary(?) switches I've laid eyes on - and you seldom see that classic label-gun anymore. You can hear samples of the box at work on Russ' site.The chip is showing signs of its age -- the power audio amplifier no longer works correctly, but the output signal can still be amplified if driving a high impedance load.
The SN94281 is a simpler version of the SN76477 chip used for sound synthesis in many older arcade machines. Nowadays the chips are often sought out for use in homebrew synth designs such as Thomas Henry's SN-Voice board.

Where do you get that special something for that special project if you aren't quite sure what it is or where to get it? Why the MIT Flea Market, of course!
The MIT Radio Society, in conjunction with the MIT UHF Repeater Association, the MIT Electronics Research Society, and the Harvard Wireless Club, sponsors a Swapfest on the third Sunday of each month, April through October. This is a place to buy, sell, and swap amateur radio, electronic, and computer equipment. Hams and non-hams alike are welcome.
I spent the day on Sunday looking through bin upon bin of connectors, resistors, capacitors, transistors, LEDs, antique electronics, and more. Over the course of the morning, I bumped into a few friends and made a few new acquaintances. My original quest was to get some birthday schwag for a party later in the day, but eventually, I started shopping for my own hardware needs. I could have gotten more, but three trips back to the car seemed to be enough.
It is refreshing to see so many people looking for supplies and tools to do creative projects. These days, people who have extra 'treasures' adorning their caves can jettison their surplus in more ways, but there is fortunately still a way to sell and buy in person. There was definitely a healthy exchange of ideas and the excitement of a great unanticipated find was definitely in the air.
What is your all time best find at the MIT Flea or similar tech-styled exchange? Where are the other places you look for and find great supplies and ideas for projects?

Johannes decided to try pushing the limits of Arduino as a desktop computing platform -
I have resently been working on a project for the arduino, called Arduputer. With the project i intended to see how much the arduino could do. The current sketch is about 13kB.FYI - As the author notes in the forum discussion, Tux the penguin only appears here as a demo graphic (sorry Linux lovers).On the arduputer I have several programs including a text editor, a simple ocilloscope and a program that shows available ram on the Arduputer.
I have modified the Ps2 keyboard library and the GLCD. In the GLCD library I added a routine for showing a picture. I used Bitmap2LCD for converting it from bmp to bitmap. The routine is a little wired so if you are going to convert a bitmap yourself, the settings are.

Neil Gaiman and Charles Vess's Blueberry Girl is a beautiful, affirming, inspiring picture book based on a poem that Gaiman wrote for Tash, Tori Amos's daughter (who is also Gaiman's god-daughter). The poem is a set of benedictions for girls, wishes for a realistically joyful life where what pain that comes only serves to make the pleasure sweeter. Vess (a well-known fantasy artist) has a distinctive style that gives the book much of its charm.
If you can read this without smiling or tearing up, you're made of sterner stuff than me.

Let her have brave days and truth.
Let her go places that we've never been;
Trust and delight in her youth.
Ladies of Grace, and Ladies of Favour,
And Ladies of Merciful Night,
This is a prayer for a Blueberry Girl,
Grant her your Clearness of Sight.
Words can be worrisome, people complex;
Motives and manners unclear.
Grant her the wisdom to choose her path right,
Free from unkindness and fear.
Let her tell stories, and dance in the rain,
Somersaults, tumble and run;
Her joys must be high as her sorrows are deep,
Let her grow like a weed in the sun...

Andrew's neglected subwoofer found new life as a mini guitar amp -
So I made the $5 Cracker box amplifier (makezine.com/09/crackerboxamp) almost a year ago, and the box I had put it in was falling apart, even though I had reinforced it with more cardboard.I too can attest to the goodness of the subwoofer-turned-guitar-amp design. With the plastic cover removed and speaker turned around, an old Altec Lansing sub has served me well as the affectionately named "Ol' Crappy" :P
Anyway, I was looking at it on my desk this morning, thinking about how it would be much better if I wasn't using the little 3 inch speaker I had in the box, when I looked over and saw this neglected subwoofer in the corner of my room that had never really been used (and probably never would be).
My first thought was to take the speaker out and use it for the amp, but when I was disassembling it, I noticed how well the subwoofer itself would work as a case for the amp. So I set to work fitting all of the pieces in, and a while later, I had a fully functional amp that looked and sounded much better than the original.
I may use the open "12v in" hole for a 9v in to power the amp in the future.

(The name only refers to the rough aesthic - it actually sounds surprisingly good!)

My bread-boarded preamp sounded just as nice as some $300 products I've seen for iPods and such. Maybe I'm just an idiot for pursuing this instead of a $2000 iPod enhancer design...

Breeze is an incredible marquetry artist. A few years ago, he stayed with us while showing his work at the Duxbury Art Association. My mother saw his work and commissioned a custom designed table inspired by her photos of Costa Rica.
T. Breeze VerDant...started his woodworking experience by building a log cabin from his own trees and rocks, hauling the logs by hand with a "come-along". He consequently demolished buildings for building materials and built another home entirely from lumber he harvested selectively from a friend's forest (thereby saving it from being clear-cut). Expressing ones self through house building is a tedious method of expression. It also consumes a lot of trees, which "Breeze" has an affinity for. "My mother knew where to find me at dinner time, she'd stick her head out of the door of the kitchen and yell.... upwards!". Breeze has run power lines, studied and practiced massage and the healing arts; He is a singer/songwriter/guitarist/poet and an activist for peace and the environment. Breezes aim with wood is to create and share the greatest amount of beauty while consuming the smallest amount of wood. Breeze has been practicing marquetry full time since 1988.

I love musical instruments. Music is sacred, it's an accessible realm that tells me that there is more that the consensus reality. It comes from within. To do the marquetry on the guitars is just great...to help create an object that has active function in the world. People hold the guitars as special to themselves and make beautiful music with them.Read more | Permalink | Comments | Read more articles in Arts | Digg this!

Mentalist and conjurer Derren Brown's taking a new show called "Enigma" on tour across the UK. Derren's a terrific performer who does an absolutely baffling mentalist act that combines applied psychology, prestidigitation, and a fabulous performing style that'll have you scraping your jaw off the theatre floor. We caught him in London last year and were just delighted. All the stuff you've seen him do on TV and YouTube? He does stuff that's that cool, except there's no camera, no edits -- nothing that could be used to simply trick you. The fact that he's a "psychic"-busting skeptic only makes it all cooler, since you know that there's a trick in there somewhere, but damned if you can find it. (Or at least, if you can, you're a lot smarter than me!)
Last year I moved to Rural Bangladesh. My work is pretty diverse, everything from hacking web apps to designing building materials. Increasingly a Linux VM on my MacBook Pro is insufficient due to storage speed/processing constraints and the desire to interface more easily with some sensor packages. There are a few issues that make that make a standard server less than desirable. This server will generally not be running with any sort of climate control and it may need to move to different locations so would also be helpful if it was somewhat portable. The environment here is hot, humid and dusty and brutal on technology and power is very inconsistent so it will often be on a combination of Interruptible Power Supply and solar power. So a UPS is a must and low power consumption desirable, so it strikes me that an Integrated UPS a la Google's servers would be handy. Spec wise it needs to be it needs to be able to handle several VM's and some other processor storage intensive tasks. So 4 cores, 8GB of ram and 3-4 TB of SATA storage seems like a place to start for processing specs. What sort of hardware would you recommend without breaking the bank?Apart from the normal background radiation of dumb Internet answers ("Why don't you buy an RV and use it to house the armed guards you'll need?") there's some good techy discussion there.

The Great Brazilian Sat-Hack Crackdown
To use the satellite, pirates typically take an ordinary ham radio transmitter, which operates in the 144- to 148-MHZ range, and add a frequency doubler cobbled from coils and a varactor diode. That lets the radio stretch into the lower end of FLTSATCOM's 292- to 317-MHz uplink range. All the gear can be bought near any truck stop for less than $500. Ads on specialized websites offer to perform the conversion for less than $100. Taught the ropes, even rough electricians can make Bolinha-ware."I saw it more than once in truck repair shops," says amateur radio operator Adinei Brochi (PY2ADN) "Nearly illiterate men rigged a radio in less than one minute, rolling wire on a coil."
Brochi, who assembled his first radio set from spare parts at 12, has been tracking the Brazilian satellite hacking problem (.pdf) for years.
Brochi says the Pentagon's concerns are obvious.
"If a soldier is shot in an ambush, the first thing he will think of doing will be to send a help request over the radio," observes Brochi. "What if he's trying to call for help and two truckers are discussing soccer? In an emergency, that soldier won't be able to remember quickly how to change the radio programming to look for a frequency that's not saturated."
The Telegraph celebrates the recently departed Clement Freud (writer, grandson of Sigmund, chef, politician, broadcaster) with this clip of the delightful old codger telling "the funniest joke ever told." I laughed aloud -- and I loved his Grimble kids' books, which were weird, subversive and funny in just this way.
Did Clement Freud tell the funniest joke ever told?
