The folks at Sparkle Labs have put up a cute project on their site. It's a simple LED circuit on a breadboard (built with their Discover Electronics Kit), with some Turkey papercraft attached, to create a Thanksgiving table decoration. This is a great way to get your kids involved in a basic electronics project that becomes part of the holiday festivities (er... for those of you in the States).

It cost the industry untold millions in actual payola, independent promoter fees, and then more than $25 million in settlements, not to mention lawyer fees. If they would have just let people share the music online, the marketing they were looking for could have been free."It really does make you wonder what goes through the minds of record label strategists. They tossed away millions paying people to get music heard, when they could have just embraced file sharing and made it cheaper and easier to get music heard without running into the legal problems of payola as well. Of course, the problem with that plan is that the labels also lose "control." They've paid to get songs on the radio because they wanted to just focus on a small group of artists who they could squeeze for as much profit as possible, dumping all the rest. File sharing makes it harder and raises the possibility that other artists might also get heard.

The Rationalizer consists of an "EmoBracelet" and an "EmoBowl" and incorporates sensors and signal processors designed by Philips. The EmoBracelet's galvanic skin response sensor measures the level of emotional arousal in a similar way to a lie detector. The result is displayed on either the bracelet or the EmoBowl as a light display that intensifies and changes to reflect the wearer's intensifying emotional arousal. At the highest emotional stress level the display has a greater number of elements moving at higher speed, and the color changes to a warning red.Concept video after the jump.

"The Book Behind the Sewer-Alligator Legend" (NY Times)Mr. May decided to go down to sewers himself to determine whether there was anything other than an excess of whiskey behind his inspectors' reports of narrow escapes from alligators. That startling description of what he found, given by the man affectionately known as the King of the Sewers and recounted by a journalist, was immortalized in "The World Beneath the City":
Alligators serenely paddling around in his sewers. The beam of his own flashlight had spotlighted alligators whose length, on the average, was about two feet. Some may have been longer. Avoiding the swift current of the trunk lines under major avenues, the beasts had wormed up the smaller pipes under less important neighborhoods, and there Teddy had found them. The colony appeared to have settled contentedly under the very streets of the busiest city in the world...
"These tales had a journalistic background," said Loren Coleman, director and curator of the International Cryptozoology Museum in Portland, Me., who has researched and written about the topic for decades. "Daley's book came along, and it was almost like independent confirmation."

Novation Launchpad - $200
With Ableton Lite bundled free of charge, this bizarre USB-powered light box is easy to set up and fun to use. An 8x8 grid of glowing pads surrounded by context-setting controls, it's a clever way to control playback of readied tracks--but not so fluid as a compositional tool. Though a gorgeous stage prop, it's not a toy, either: don't get it for folks who don't know a DAW from a doorstop.

HTC Imagio $200 w/2-year contract
You've seen HTC's Imagio--it's the one in those cheeky Verizon ads that mock AT&T's dismal 3G network. Consider your needs. It'sthe best WinMo iClone yet, but being the second best phone of 2007 still isn't good enough if you're a contract-free agent. HTC's concealment of Windows' obsolete clunker OS is an amazing feat--it swipes, it scrolls, it looks good--but at every turn there's another reminder, a performance or UI irritation that takes the shine off. Droid is better, and so is an iPhone--but don't count it out without a fiddle at the mall kiosk.
CardScan for Windows Mobile - $15, out soon.
Dymos's CardScan scans business cards with a WinMo 6.5 cellphone's camera, performs character recognition, then syncs up the data with your address books. It's as simple as that, but requires at least a 2-megapixel camera. The weirder the card's typography, the more cleanup work you'll have to do. That said, it's as good as dedicated business card scanners--Dymo's putting its own hardware on the critically endagered gadget list!
Motorola Debut i856 - $100 with a 2-year Sprint contract, $150 contract-free with Boost.
This chunky slider-phone has push-to-talk, GPS and a 1.3MP camera. Perfectly serviceable, its old-school low res display and short feature list limit its appeal, but the real killer is price: even for $100, you can get something better.

Moshi Voice Control Travel Alarm Clock - $25
There are two things you need to know about this. Firstly, it is incredibly small, small enough to fit in your pocket. Secondly, the voice recognition works perfectly. Okay, so there's a third thing: you have to press a button to get it to accept voice commands. The size makes it good for travelers or the cramped, but the voice thing is only really for those who hate figuring controls out.

My buddy Jon makes these awesome little puzzle boxes from acorns. There are four shown in the video: one pair consisting of a smaller hinged acorn that nests, matryoshka-style, inside a larger one with a wire spring latch; a larger, locking nut that is opened by removing a small pin; and, finally, a large hinged version that is unlatched by knocking it against a surface from a certain angle. Besides this post, the project doesn't have any web presence to speak of, but Jon says its fine to e-mail him directly if you are interested in more information.

After posting his excellent series of instructional videos on YouTube for 3-string cigar box guitar, Keni Lee Burgess has started posting videos for the 4-string cigar box guitar.
We used to call our original video episodes "BBTV," and we don't anymore. We call it Boing Boing Video now.
Well, ladies and germs, allow me to present to you the inheritor of that acronym: BBTV is now the name used by Bedbug TV, a guy who makes episodic web video content about how to deal with bedbugs. I think he runs a pest control company. His videos crack me up, particularly the first 15 seconds or so. The one above deals with how to cope with bedbug infestations in your home electronics products, like if your "electronics, books, paintings, pictures, dvd players, radios, alarm clocks, boxes and just clutter in general" is crawling with bedbugs.
I stumbled on them because back in 2007 when we started Boing Boing TV / BBTV, I created a Google News vanity search for "BBTV." We stopped using the acronym in 2009 and switched to "Boing Boing Video," but recently I'd begun receiving new hits on the "BBTV" vanity search -- all of them bedbug videos. B-B-T-V. Four immortal letters. Immortal and unkillable, just like bedbugs.
BBTV.
Disclaimer: I may also be lying to you, and all of this might be a postmodern viral marketing performance art campaign to promote Boing Boing's online video project.

The online dating site OKCupid has a blog where they post analyses of the tons of data they collect, and it's really fascinating.
For instance the attractiveness of woman on OKCupid, as judged by the men on OKCupid, is a symmetrical bell curve. In other words, half the women are better-than-medium looking and half are worse-than-medium looking. But OKCupid's women rate 80% of OKCupid's guys as worse-than-medium looking! Even more interesting: while men are much more likely to send messages to the most attractive women, woman send are much more likely to send messages to men who are slightly less-than-average looking.
As you can see from the gray line, women rate an incredible 80% of guys as worse-looking than medium. Very harsh. On the other hand, when it comes to actual messaging, women shift their expectations only just slightly ahead of the curve, which is a healthier pattern than guys’ pursuing the all-but-unattainable. But with the basic ratings so out-of-whack, the two curves together suggest some strange possibilities for the female thought process, the most salient of which is that the average-looking woman has convinced herself that the vast majority of males aren’t good enough for her, but she then goes right out and messages them anyway.Your Looks and Your Inbox (Thanks, Vann!)


Blinking an LED and transmitting text to a serial terminal is not the most exciting thing in the world, but it's very cool to breathe life into a balky computer, even at the most basic level. Also, I have worked with enough development tools to know that it can be a lot of work going from the first build to basic function. Many vendors, like National Instruments, Texas Instruments, and others, have recognized the value of making a good first impression, while preserving all the power and sophistication available to the user. I do understand that ease of use can be hard to achieve, especially with complex, powerful tools. I own a small Sherline CNC mill that I built up with 3-phase brushless motors, a custom motor controller, and optical limit switches. It was a fun project, especially building the machine and seeing it run for the first time. I use it much less frequently than I would like, but it's been very handy for many of my projects. The mill is powerful enough for small projects, and simple enough that I can ignore it for several months without forgetting how to use it. I also have a little experience running large industrial CNC mills. I could make a lot of cool devices if I had a 5-axis commercial CNC machine, but using the machine effectively would require a substantial and continuous investment of time. Given what can go wrong, improper operation resulting from infrequent practice can be disastrous.
I've experienced a similar comparison between Windows Embedded CE and other prototyping and development tools I've worked with. For simple embedded projects, I use a wide variety of tools, from Arduino to ARM and others. I like to program in C or C++, using assembly only when I have to. I have been known to slip uLinux into projects when I can. These systems are like the Sherline CNC mill. They have limitations, yet are valuable from an ease-of-use perspective. Windows Embedded CE is more like the large industrial CNC mill - very powerful once time has been invested.

The best way to fight piracy? Got e-book shoppers accustomed to buying from legitimate sources before it's too late. That means easy downloading, fair prices and the ability to move content easily from machine to machine within a household. Use of the standard ePub format and the end of traditional DRM could go a long way in that regard.Instead, they're likely to go in the other direction (they always do) and try to raise the DRM walls higher in a futile effort to "fight" piracy. Of course, as we discussed nearly a year ago, the ebook industry could really use more piracy, because it's actually a great indicator of what people really want. And, of course, locking up content with more DRM will only serve to take away value. If there's growing piracy, that just means the industry is putting up unreasonable barriers. Hopefully publishers realize this before totally screwing things up, but somehow it seems likely they'll make all the same mistakes as the music industry.

On Sunday, a man named Sal9000 married the love of his life. Her name is Nene Anegasaki, and she lives inside of a Nintendo DS video game called Love Plus. The wedding took place during a Make: Japan meet-up held at the Tokyo Institute of Technology. In attendance were a live audience, an MC, the bride's virtual video game girlfriend — who made a speech — and a real human priest.
The event was livecast on Nico Nico Douga, a popular video sharing web site that I wrote about in Wired Magazine back in 2008. (Watch this clip of hot shot Wired folks making total fools of themselves on Nico Nico Douga.)
Nico Nico Douga is home to thousands of video projects by anonymous users — mashups of original art, pop music, anime, and web memes that only an insider to Japanese web geek culture can completely decipher. Sal9000 is an active member of the Nico Nico Douga community, so it was important to him that his offbeat wedding ceremony was broadcast on the site. The footage seen here of Sal and Nene tying the knot between real and virtual is a highly imaginative, multimedia project orchestrated by a guy determined to officiate his devotion to his video game, and to pay homage to the otaku subculture that nurtures this type of creativity. Enjoy!

So, if I go directly to butterflyphoto.com, I pay $699 with 0% cashback. If I use Bing Cashback, I pay $758 with 2% cashback, or $742.84. Using Bing cashback has actually cost me $43.84, giving an effective cashback rate of -6.27%. Yes, negative cashback! Is this legal? False advertising? I don't know, but it's pretty sketchy.Microsoft responded and called this "an isolated instance" that it had missed with its tools that try to prevent merchants from gaming the system this way. Still, perhaps rather than sending out legal nastygrams and PR pablum to people discussing these things, Microsoft should focus on actually making sure that Bing's Cashback bribery program actually works correctly and safely.
The problem doesn't end there. Using Bing has tainted my web browser. Butterfly Photo set a three month cookie on my computer to indicate that I came from Bing. Any product I look at for the next three months may show a different price than I'd get by going there directly. Just clicking a Bing link means three months of potentially negative cashback, without me ever realizing it. I'm actually afraid to use their service even just to write this, because it may cost me money in the future. If you've been thinking about trying out Bing Cashback, you may want to rethink that.

The holiday season is a great time of year, especially for kids! This year I came up with a list of products that will inspire your children, and let you in on the fun too! Many of these recommendations were inspired by my own childhood. I certainly made a lot of kits growing up, and I've included a few of my favorites in this list! Remember, the holiday season is a great time to start a new project with your kids. Teach them something new, get involved....and don't forget to have some fun!
Haba architectural blocks (OOMPA, $16.49 - $89.99)
I was lucky enough as a kid to have a really cool set of blocks that were made by my grandfather. We made houses, mazes for our little rodent friends, racetracks, and just about anything else you could imagine. Most blocks today are standard squares and rectangles, maybe an arch or two. Haba blocks are the exception. They make an incredible variety of blocks, including Baroque Building Blocks, the Coliseum, Leaning Tower of Pisa, Castle parts, and a lot more. Be sure to click through all the pages to see the complete line of Haba architectural building blocks.
Drawdio Kit (Maker Shed, $19.50)
Drawdio is a really fun DIY electronics kit and musical instrument. It's easy to assemble, and fun to hack! Drawdio has been kid-tested at my house for many hours, and is a hit with everyone who tries it! The kit requires some soldering, but you could make that into a great learning experience for your little engineer in training.
Drawdio is an electronic pencil that lets you make music while you draw! It's a great project for beginners: An easy kit with instant gratification! Essentially, its a very simple musical synthesizer that uses the conductive properties of pencil graphite to create different sounds. The result is a fun toy that lets you draw musical instruments on any piece of paper.
Telescope (Orion, $49.95 - $300+)
I have to admit, I never owned a telescope, but that may change soon. Recently, I've been researching telescopes, both DIY and commercial versions. I plan on getting a truss tube Dobsonian scope one day, but they're fairly expensive, so I might have to wait a while longer, or try to make a DIY version. Orion seems to have a nice selection of beginner scopes, at reasonable prices. However, do your research before making any large investment.

So I was excited when Weta offered to send me two of their latest rayguns for review. The new line, "Dr. Grordbort's Rayguns," are not made from cast-iron, but rather from "Real Imitation Metal" (e.g., molded plastic), and comes in toylike packaging that wouldn't look out of place in a Toys R Us aisle. But as with the more expensive originals, the detail on the unit is exquisite, the best I've ever seen on a mass-produced item (this even carries over to the teeny-weeny desk-toy-sized "Minisculized" versions, which have details that even look good under a magnifying lens). They're still not cheap -- the "Righteous Bison" they sent me costs about US$85 -- but they're a lot more affordable than the hand-made iron monsters.
I have a small collection of rayguns here, some from professional houses, others hand-crafted by Etsy makers, but the Righteous Bison is the first plastic/mass-made version I'd consider adding to my wall. It's a beautiful piece, truly. And the little teensy Victorious Mongoose desk-toy gun (with its own stand) now lives beside my monitor, where I can enjoy it every time I look up.
Dr. Grordbort's Rayguns from Weta
With so much cool stuff popping up these days you notice when something truly draws awe. Qi Pan, a PhD candidate at the Engineering Department of Cambridge University, has developed a novel approach to capturing 3D objects with a standard webcam. Called ProFORMA, Pan's software digitizes and image maps an object in 3D as the user rotates it in front of the camera in realtime. Additionally, the physical object can be used as a marker to overlay the virtual object in realtime for potential Augmented Reality applications. [via Core77]
As the user rotates the object in front of a stationary camera, a partial model is reconstructed and displayed to the user to assist view planning. The model is also used by the system to robustly track the pose of the object. Models are rapidly produced through a Delaunay tetrahedralisation of points obtained from on-line structure from motion estimation, followed by a probabilistic tetrahedron carving step to obtain a textured surface mesh of the object.Read more | Permalink | Comments | Read more articles in Imaging | Digg this!

I planned on writing an entry about burning bootloaders and updating the firmware, but I just realized my kit comes ready to go! Yay! This is a major advantage to purchasing the Generation 3 Electronics kit. If you're making you own boards, be sure to check out these detailed instructions on burning bootloaders and updating firmware before going any further.
Here's the description of the Generation 3 Electronics kit [Mostly Assembled]:
This is a kit of mostly assembled electronics. All of the hard stuff is taken care of for you, and the only soldering that remains is the opto endstops which are very simple (only through hole components, no SMT). The stepper drivers, extruder controller, and motherboard all come fully assembled and ready to use. The extruder controller and motherboard have been pre-programmed with the MakerBot firmware and Arduino bootloader.
I know, I know, it's been a while since my last entry, and I apologize. The truth is, I was a bit under the weather last week, and my CupCake CNC kit had to sit and wait patiently for me to recover. The good news is, I'm feeling much better now and am super motivated to start printing parts! The next entry will be packed with CupCake building goodness. Promise!

Next up, making the pulleys and enclosure. As you can see, I chose a butchers wax finish. It's nontoxic, and nonflammable, which makes documenting it in my studio a lot easier. Also, it preserves the beauty of the wood, including the laser burns! Besides, if I don't like it, I can always cut out a new enclosure.
Ask questions! Do you want to see a better picture of a particular part, a different camera angle, a video perhaps? Maybe you have a suggestion for a cool mod or hack? Let me know in the comments. I'll try to answer them as best as I can. Thanks!
Build history:
Police routinely arresting people to get DNA, inquiry claims (Image: DNA Molecule display, Oxford University, a Creative Commons Attribution photo from net_efekt's Flickr stream)The highly critical report from the government's advisory body on the development of human genetics is published as the number of innocent people on the database is disclosed to be far higher than previously thought ? nearing 1 million.
The commission says the policy of routinely adding the DNA profiles of all those arrested has led to a highly disproportionate impact on different ethnic groups and the stigmatisation of young black men, with the danger of their being seen as "an 'alien wedge' of criminality"...
The chairman of the commission, Prof Jonathan Montgomery, said: "It's now become pretty routine to take DNA samples on arrest. So large numbers of people on the DNA database will be there not because they have been convicted, but because they've been arrested."
He said the commission had received evidence from a former police superintendent that it was now the norm to arrest offenders for everything possible. "It is apparently understood by serving police officers that one of the reasons, if not the reason, for the change in practice is so that the DNA of the offender can be obtained," said Montgomery, adding that it would be a matter of very great concern if this was now a widespread practice.

UNDERCOVER ?GRACE? (via JWZ)
Futurismic's Tom Marcinko does a great job of putting this in context, rounding up several links to other good commentators around the web. In a nutshell: science is about the advancement of competing theories and the evaluation of these theories in light of evidence. The East Anglia Climate Research Unit's scientists disagreed in some particulars, and used peer-review to resolve them (and continue to do so). No one is paying them to cover up evidence that climate change isn't real or isn't caused by humans -- but they are conducting science the way that scientists do.
Smart enough to hack, not sophisticated enough to appreciate the daily give-and-take of how science works-is that how we nonscientists are going to approach critical issues? Maybe we can do better than that.Those hacked climate e-mails: Good scientists, poor conspirators
Streets With No Name (via Making Light)
This past winter, the snow stayed so long we almost forgot what the ground looked like. In Detroit, there is little money for plowing; after a big storm, the streets and sidewalks disappear for days. Soon new pathways emerge, side streets get dug out one car-width wide. Bootprints through parks veer far from the buried sidewalks. Without the city to tell him where to walk, the pilgrim who first sets out in fresh snowfall creates his own path. Others will likely follow, or forge their own paths as needed.In the heart of summer, too, it becomes clear that the grid laid down by the ancient planners is now irrelevant. In vacant lots between neighborhoods and the attractions of thoroughfares, bus stops and liquor stores, well-worn paths stretch across hundreds of vacant lots. Gaston Bachelard called these les chemins du désir: pathways of desire. Paths that weren't designed but eroded casually away by individuals finding the shortest distance between where they are coming from and where they intend to go.
By studying mice and human cells, they found the harmless bacteria did this by making a molecule called lipoteichoic acid or LTA, which acted on keratinocytes - the main cell types found in the outer layer of the skin.Dirt can be good for children, say scientistsThe LTA keeps the keratinocytes in check, stopping them from mounting an aggressive inflammatory response.
Head of the research Professor Richard Gallo said: "The exciting implication of the work is that it provides a molecular basis to understand the hygiene hypothesis and has uncovered elements of the wound repair response that were previously unknown.

We are surprised and unpersuaded by assertions that disclosures of basic information about the negotiation would present a risk to the national security of the United States, particularly as regards documents that are shared with all countries in the negotiations, and with dozens of representatives of large corporations. We are concerned that the secrecy of such information reflects a desire to avoid potential criticism of substantive provisions in ACTA by the public, the group who will be most affected by the agreement. Such secrecy has already undermined public confidence in the ACTA process.... We firmly believe that the public has a right to know the contents of the proposals being considered under ACTA, just as they have the right to read the text of bills pending before Congress."Unfortunately, these are just two Senators. Supporters of ACTA likely have many more who will blindly fight to keep ACTA secret and get it approved with little or no substantive input from those it will impact most.

Tasering just isn't for 10 year olds, a UK man invented a lobster zapper that some feel is more humane than just tossing them in boiling water. I would like to try this electric lobster they speak of. Looking at the photo, it looks like two big metal plates that "zap". The company is called "CrustaStun".
A company in the United Kingdom is about to lift the lid on a device that zaps lobster with electricity to kill them, and the inventor said Wednesday his humane alternative to boiling is about to give the entire industry a jolt.
British entrepreneur Simon Buckhaven said the CrustaStun system, developed over the past decade by his company Studham Technologies Limited, near London, kills the lobster with an electric charge, so the crustacean feels no "pain or distress."
The application of a stun (110 Volts - 2-5 amps) causes an immediate interruption in the functioning of the nervous system of the shellfish. By interrupting the nerve function, the shellfish (be it Crab. Lobster or other) is unable to receive stimuli and thus by definition, cannot feel pain or suffer distress (Dr. Dave Robb 2000 - Bristol University - paper on sentience in Crustacea, Baker 1975, Jane Smith 1991, Bateson 2000, Sherwin 2000 & Gregory & Lumsden 2000). The prolonged application of the stun causes a permanent disruption which kills the shellfish.Sounds tasty! This isn't the only lobster tech from Crustapreneurs...

In short, Hathaway took the idea of providing people with pre-shucked lobster, researched it and found that the government had been looking for ways to extend the shelf life of foods without freezing or irradiation for years. He discovered there are only two companies in the world that make machines that use extremely high water pressure to process foods and give them extended shelf life. (The government applied that process to its MREs, or meals ready to eat, for the military.) About a year and a half ago, Hathaway learned that this process also separated shellfish meat from the shell and that several Canadian lobster processors were using this system. Hathaway came up with the money for a machine. He started the new business by qualifying for a block grant from the state (which had a matching fund) and through private investors. Then, instead of having an architect design a fancy, state-of-the-art building on the coast, he decided to go back to his roots. He took a space in the nearly empty, old Etonic sneakers factory in Richmond, a slightly down-at-the-heels river town in central Maine between Wiscasset and Augusta, an area with people needing work. In April 2006, he opened his new company, Shucks Maine Lobster.
Buckhaven, meet Hathaway.

Yesterday I went to Tokyo MAKE Meeting 04 with Gianluca Martino: a member of the Arduino team. He has been super popular and he really appreciated the Japanese Arduino scene. During the show Gakken displayed the prototype of the JAPANINO (Arduino clone). It will be released next spring in the Otona no Kagaku (in Japanese it means “Science toys for adults”) magazine series with a Persistence of Vision plastic Toy with color LEDs. The price tag will be less than 3500 yen (ca$35) and it will help a lot of people to get into the “Makers” scene. I’m doing consulting for Gakken on this project so I can not reveal all details but this release will definitely make the Japanese Arduino scene the biggest in the World as in a couple of months the magazine will probably sell what the original Arduino sold worldwide in the last years. As all Otona no Kagaku issues there will be also a magazine with many information about original Arduino and simple guide for beginners. There will be a Japanese IDE downloadable from Gakken website but foreign users can use the standard Arduino software.Read more | Permalink | Comments | Read more articles in Arduino | Digg this!



There are woodcarvers, and then there's Gary Tatman, of Glen Burnie, Maryland. Gary explains his incredible work on Hemmings Auto Blog:
You're correct in your assumptions- these carvings start out as a block. I use the Internet motorsports archives to obtain enough photos of the project car for detailed areas such as interiors, engine compartments, suspensions etc. Once all data and photos are assembled, a ratio has to be determined for scaling (in reference to actual body size). Then all areas can be measured and used in the ratio to determine the actual size of the pieces. Once this is accomplished, the design needs to be drawn on the block, for references while shaping takes place.Read more | Permalink | Comments | Read more articles in Crafts | Digg this!
What could be cooler than pop-up books dioramas? How about if they were life-sized? That's exactly what designers Liddy Scheffknecht and Armin B. Wagner have created with their pop-up office. Unfortunately, it doesn't look like the furniture is strong enough to use, but what fun! [via neatorama]

Interesting quote from today's big education announcement (MAKE is part of it!). Reminds of when Dean Kamen says "We are what we celebrate"...
Mr. Obama said academics should be receiving an athletic-like focus. And as he presented a set of initiatives intended to improve the science and math scores of American students, he announced that the White House would begin holding an annual science fair starting next year.“If you win the N.C.A.A. championships, you come to the White House. Well, if you’re a young person and you’ve produced the best experiment or design, the best hardware or software, you ought to be recognized for that achievement, too,” Mr. Obama said. “Scientists and engineers ought to stand side by side with athletes and entertainers as role models, and here at the White House, we’re going to lead by example.”
He added, “We’re going to show young people how cool science can be.”
Mr. Obama presented the “Educate to Innovate” campaign on Monday. Sally Ride, the first American woman in space, was on hand, along with students and dozens of scientists and other administration officials. After speaking for about 15 minutes, the president inspected the “Cougar Cannon,” a device made by two students that is intended to scoop up and toss moon rocks.

I've been working on microscope sets for Maker Shed. Until now, the only microscope set the Shed carried was the Thames & Kosmos TK2. That's a decent set, at under $100, but it's still a toy. We wanted some better sets, so I put together three, which we imaginatively named the Basic Microscope Set, Intermediate Microscope Set, and Advanced Microscope Set. The sets differ only by microscope is included; the accessories are all the same.
I've always been annoyed by the accessory selection in typical microscope sets, which seem to be chosen for cheapness rather than usefulness. A typical set includes a few prepared slides, which are usually of such poor quality that they're not worth having. Most sets include a "cleaning kit," which again is cheap and of limited use. (If you keep your microscope covered with a plastic bag, the optics should remain clean indefinitely. When they do get dirty, you can clean them with a soft cotton cloth and a drop or two of window cleaner.) And you usually get maybe a dozen blank slides and a a few coverslips, which is barely enough to get started. In other words, the typical accessory set is pathetic, but has the advantage from the seller's point of view of being cheap to include and they make for an impressive-looking list and product image. I knew we could do better.
When I sat down to make a list of accessories to include, I realized that I didn't need to re-invent the wheel. When I started work on the forensics book, I bought a microscope (not coincidentally, the Shed now carries that model, including the objective upgrades). When I ordered the microscope, I also ordered accessories, so all I had to do was check back to see which accessories I ordered with the microscope.
First up were slides and coverslips. I actually ordered three gross of slides (six boxes of 72) and several ounces of different coverslips (at about 100 to the ounce). That's obviously overkill for a set, so I decided to include one box of 72 slides and an ounce of coverslips. Glass, in both cases. Yeah, glass breaks, but plastic slides are a pain and plastic coverslips are really poor optically. For slide making, I included plastic forceps, which are better than metal ones for handling coverslips and most specimens, a pack of ten polyethylene pipettes, and bottle of glycerol for making temporary wet mounts. I was going to include a bottle of permanent mounting fluid, but the good stuff is expensive and would needlessly boost the price of the set. A small bottle of colorless Sally Hansen's Hard As Nails from the drugstore costs only a couple bucks and works about as well. No one ever thinks about how they're going to store the permanent slides they make, so I included a slide storage box. Oh, and because a beginning microscopist needs lots of interesting things to look at, I included one of our Microbe Motel kits, so they can grow their own microorganisms. (Yeah, the name is cute, but it includes everything you need to culture bacteria and other microorganisms. Real stuff, not shoddy plastic junk.)
I dithered about which stains and supplemental reagents, if any, to include. I have more than 30 biological stains and reagents at my microscope workstation, but real biostains and reagents are relatively expensive, so including even a few of them would boost the prices of the sets for something that some people wouldn't use. Then I was struck by a cunning plan. I headed for my local strip mall.
At Walgreens, I scored one ounce bottles of iodine tincture and gentian violet and a pint bottle of ethanol for about $7 total. At the supermarket, another couple of bucks got me a box of four food coloring dyes, two or three of which are actually useful biostains, and a bottle of distilled white vinegar (acetic acid). And at the pet store next door, I picked up a small bottle of methylene blue for a couple bucks. So, for a grand total of about $12, I ended up with a pretty decent starter set of biological stains and reagents, including everything necessary to do basic biostaining and even Gram staining. Including all that stuff in the microscope kits would boost their prices by a lot more than $12, so I decided it made more sense just to recommend kit buyers make a quick trip to the local mall. Our beancounters probably hate that, but set buyers should love it.

"Galileo's missing fingers found in jar"The museum plans to display the fingers and tooth in March 2010, after it re-opens following a renovation, Galluzzi said.
The museum has had the third Galileo finger since 1927, so the digits will be reunited for the first time in centuries, he added.
Removing body parts from the corpse was an echo of a practice common with saints, whose digits, tongues and organs were revered by Catholics as relics with sacred powers.
