Daniel Reetz must be one happy maker! Not only did he create this fantastic DIY book scanner, but he won an Epilog Zing 16 Laser for his efforts! From the press release:
Epilog Laser, the leading producer of CO2 and fiber laser engraving and cutting systems, and Instructables.com are pleased to announce Daniel Reetz, Fargo, N.D., is the grand-prize winner in the Epilog Challenge. Reetz will receive a new Zing 16 Laser engraving/cutting system for his innovative and eco-friendly "DIY High-Speed Book Scanner from Trash and Cheap Cameras". Reetz's winning instructable was one of 478 entries in the Epilog Challenge.

Daniel says:
"I have strong 3D modeling skills, and I'm planning to use the Zing to do all kinds of rapid prototyping. The Zing will allow me to rapidly make stencils and solder masks, and to prototype new camera mounts quickly. But I'm most excited about using the Zing to pursue an exciting new field of imaging called computational photography," Reetz said. "Really, without Epilog and Instructables, none of this would have been possible."
I've been test driving a Zing myself, which I'll be doing a full review of soon, and I have to agree with Daniel: having a laser cutter at your disposal is a game changer when it comes to quickly realizing your designs in the physical world. Great job, you lucky son of a gun!

If you want to drive like a rocketeer, or maybe you just don't want to be bothered with checking your air pressure, then take a look at the Tweel.
Airless tires could solve a number of problems associated with pneumatic tire technology. cnn
The Tweel, an experimental tire and wheel combination developed by Michelin, is designed to replace today's air-filled tires. Flexible polyurethane spokes deflect over obstacles.
The technology has been under development for a few years.
Recently, I had a flat on my vehicle, and left the spare off of the holder while the repair was being done. I realized how heavy the tires on the car are every time I opened or closed the back gate. Tires weigh at least a couple hundred pounds of the vehicle's weight, decreasing fuel economy through inertia. I doubt that the tweel as configured would work well in snowy driving, it looks like the snow and ice would jam into the gaps and throw the balance way off, making for a very bumpy ride. Certainly, there are people working up solutions to that problem.

(Rudy Rucker is a guestblogger. His latest novel, Hylozoic, describes a postsingular world in which everything is alive.)
I've always been fascinated by ants. Look at these guys taking apart a dead fly.
I found a (somewhat slow) website called AntWeb with a lot of ant pictures, like, of all 28 different genera of the ant subfamily called the ponerine ants.
There's a striking similarity between ants and motorcycles, I've always thought---maybe there's something about that rear ant bulge (known as the gaster) resembling a gas tank.
In the early 1990s, when the notion of Artificial Life was big, I wrote a Windows program called Boppers: Artificial Life Lab, which incorporated a kind of virtual ant farm. I did the work at Autodesk, and now you can get the program as a free download.
In my usual "transreal" fashion (here's an essay called "A Transrealist Manifesto" that explains that word), I wrote an SF novel about my stint at Autodesk, including some virtual ants that take over the world.
I just noticed that on Google Books you can find part of the text of my Autodesk ant novel, The Hacker and the Ants, Version 2.0. Why 2.0? Well, the book first came out in 1994, and when I republished it in 2003, I upgraded some of the tech and gave it a slightly happier ending.

If it was for some reason hard to see clouds, can you imagine how much people would pay for the privilege? Like, if there was only one spot on Earth that had clouds, everyone would be going there and having these big spiritual experiences just from seeing the clouds.
This is a cloud I saw in Big Sur. We get so much beauty for free in life.
I always enjoy photos of weird and unusual clouds, and I found a cornucopia of them on the over-the-top image site, "Dark Roasted Blend".

Milojo Productions (brainchild of Kelly Ripa and Mark Consuelos) is now casting women with fabulous ideas and great personalities from across America for a new series. The show, set to air on TLC, takes a selected female inventor through the journey of realizing their dream. It's an opportunity to get your product developed, manufactured, marketed, and finally sold on The Home Shopping Network.The show's casting directors will be accepting submissions through GotCast until the last week of June.
Here's what the video app needs to be:
30-Second Verbal Pitch - Briefly introduce yourself and your product with an intriguing couple of sentences that lets us know what your invention does without having to physically demonstrate it.
Component II: 2-minute Demonstration - Show us your product invention anyway you like, but it must include the demonstration of a working prototype, and it must be done in two minutes or less!
Component III: Bio - give us a little bit about you and perhaps the history of your invention! This is a chance to really let your personality shine through.
Who would you nominate? What would you like to see invented?

XelaTeco is an organization that helps gather and distribute technologies in the communities of Guatemala.
Xeni Jardin covered the story with photos and audio on NPR's Day to Day.
Xela Teco builds environmentally friendly technology that can be used to bring survival basics to poverty-stricken villages in the Mayan highlands: clean water, electricity and fuel.

[Photo from AIDG on Flickr]
XelaTeco is supported in part by the sustainable design brain trust of AIDG, Appropriate Infrastructure Development Group.
The Appropriate Infrastructure Development Group (AIDG) helps individuals and communities get affordable and environmentally sound access to electricity, sanitation and clean water. Through a combination of business incubation, education, and outreach, we help people get technology that will better their health and improve their lives.
XelaTeco opened its doors in Quetzaltenango (Xela), Guatemala in the summer of 2005 after an intensive search for engineering talent at local universities and engineering schools. The highly skilled team that came together was comprised of 10 Guatemalan workers, of which 3 were women. The combined skill sets of the team ranged from accounting and civil engineering to electronics and metal casting, many of the essentials for completing the varied projects they would soon undertake.
If you have experience working with sustainable technologies in communities, share them with us in the comments.

"Repurpose", an awesome little documentary short by Jack Oatmon. The video is centered around Montreal's Foulab hardware hacking group and aims to introduce the hackerspace concept to newcomers.
Why are more and more hobbyists experimenting with hacks and circuit bends? What relationship does this imply about consumer society and technological advancement? Is this a real-world analog of 'user generated content'?hmmmm ... why hack/mod/make your own tech... Because it's incredibly fun! Ok, perhaps my view is a bit too subjective to give a completely accurate assessment of hacker motivation. Handmade and high tech have been valued cultural qualities for a while - it's now simply easier than ever before for those two to overlap. ... like I said -- fun!

Media literacy builds an understanding of the role of media in society as well as essential skills of inquiry and self-expression necessary for citizens of a democracy. (Source: Center for Media Literacy)

Inside this Media Literacy Digest:
I finally got around to capturing a few thoughts on CCK08.
I’ve posted an overview of the course (as well as an earlier rudimentary attempt from 2002) on my connectivism blog: Socialization as information objects.
Now, to get ready for CCK09…
The Social Data Revolution(s): “In 2009, more data will be generated by individuals than in the entire history of mankind through 2008… The second data revolution brought about a new dimension to data creation: users started to actively contribute explicit data such as information about themselves, their friends, or about the items they purchased. These data went far beyond the click-and-search data that characterized the first decade of the web.”The discussion of social data and expectations of consumers / end users resonates with my experiences. I no longer seek information for information itself. Whether looking for a hotel or purchasing a product online, I seek social information such as ratings, comments, or event communities. However, I doubt the opening throw-away statement of more data being generated in 2009 than in all previous history. Journal of the History of Ideas (access likely restricted) has an issue on on early information explosion that challenges assumptions that our generation suffers more under abundant information than previous generations.
Videos of two presentations I recently delivered in Iowa and New York:
Talk of technology quickly turns into talk of power. Who has it (power)? By what means did they attain it? By what means do they hold it? What are they attempting to do with it?
Technology embodies ideologies, and the choices made by its designers influence what its users will be able to do (or not do).
Learning management systems (LMS) - in contrast with personal learning environments / webs / networks - enable certain approaches to learning while discouraging others. An LMS also supports and fosters a certain relationship between the educator and the learner.
The ability to open or close a discussion forum or to grant and deny course access is fundamentally imbued with power. It is little surprise, therefore, that governance and public engagement are influenced by technology.
Open tools will produce open conversations and open thinking.
Public Engagement. Public Empowerment addresses the relationship between tools / technology, ideology / governance, and power:
Direct engagement in politics has been the purview of an educated and powerful few until recent times. Indeed, the role of the politician, and the executive that serves him or her has largely been to tell us, the sheep-like masses, what is good for us and to expect us to blithely follow along. We change our minds only in the face of corruption and excess, and exercise our democratic rights to switch to a lesser evil at times of election. But oh, my! How the world has changed. …In a hyperconnected world, our ability to readopt these denser forms of association, made sustainable by tools such as social networks, become reality. We become the true global village, as much the neighbor to the bloke next door as some geographically remote but by association, close, neighbor with whom we share an interest.The article occasionally moves into the Land of Happy Hype, but the central message of increased engagement in civic discourse enabled by participatory technologies is important to share.
I have a few weeks of travel coming up (first to Senegal for workshops as part of a Soros Foundation grant & elearning Africa, back to Winnipeg for a library conference, and then to Italy for the Enterprise 2.0 forum).
In preparation for the enterprise 2.0 event, I’ve been reviewing resources on how organizations are using social media.
35+ examples of corporate social media presents a (very) brief overview of how various organizations are beginning to use social media. Details are limited on the effectiveness of the projects, but it’s starting to feel like the mid-90’s when companies were proclaiming “we now have a web site!”.
Underneath the hype of unrealistic expectations and attention grabbing headlines, the web developed into an indispensable part of our interaction with information.
The hype of “we’re doing social media!” will likely also yield to foundational changes in how we interact with each other.
Techcrunch reviews conference discussions of technologies trends for 2009.
Trends presented are fairly obvious (which is to be expected when the analysis cycle is as short as a year): next generation technology users, mobile devices, digital displays, etc.
The focus on unstructured data (they suggest within five years, 80% of enterprise data will be unstructured) and distributed webs (social networks) are important for educators to consider.
Last week, Martin Weller and I hosted an online conference to discuss the future of courses: From Courses to Dis/Course.
The recordings are now available.
At this stage, they are long, unedited Elluminate recordings. Which means you have to advance the recording until you get to the presentation you would like.
As much as I love Elluminate, the inability to get individual recordings is a challenge. If I suddenly inherit time, I’ll chunk the recordings with Camtasia. Or if someone else is eager to do so… :)
Education’s sibling - the news industry - continues to suffer under the impact of freely available content and increased end user control permitted by the web. But it is not a field that is going away quickly or quietly. Consider the suggestion that the internet is killing news:
But, content is not necessarily news. News is the verifiable facts that trained, responsible journalists… often spend hundreds of hours tracking down and sifting through and verifying to get to the truth. Real reporting is time-consuming and expensive. It requires a level of investment that many traditional print and broadcast news organizations can no longer afford in the face of the tsunami of free content that is the web.The real problem is not that we have free content (as the article goes on to suggest, while classifying instances of effective amateur journalism as rare). The real issue is that free content contrasts with the existing infrastructure of newspapers and journalism. Quality “control”, vetting, and rigorous research can (and will) be a part of open content. The models will be created over time. The newspaper industry did not emerge wholly as we know it today. It evolved in response to needs of readers and members of society. Those who lament the decline of newspapers overlook the likelihood of a similar prospect for world of open content.

Hands-On With A Whippit-Powered Travel Espresso MakerA typical regulator might be two inches in diameter. Much too large for the TWIST. The task of shrinking the apparatus down without losing efficiency and safety went to Gecko, a firm that collaborated on the Herman Miller Leaf Lamp and has built pneumatic devices on cruise control missiles for defense industry contractors (really).
Their creation: a regulator that's about the size of half a grown man's pinky nail. Once the pod develops its own pressure, the regulator in the handle shuts off the pressure. And there's also a secondary safety valve, in case you put in too much coffee. In time, too, their small, main regulator could be applied or licensed out to other hardware.
For now, O'Brien is focused on the TWIST. And as we continue to chat, all I'm focused on is the taste. He takes a preloaded cup, gets some hot water from the cafe, puts in 3.5 oz., pulls the trigger to release the gas (it's cold, but expands rapidly from the hot water), and begins the pour...

The backrest and headrest are screwed together by a pair of aluminum supports. This unit is suspended on the seat via two connection points in the armrests. The armrests are screwed to shock mounts on the interior of the backrest shell, allowing the backrest and headrest to flex when the chair is in use. This is part of the chair's unusual design, as well as one of its biggest flaws. The rubber washers are solidly glued to the plywood shells, but have been known to tear free when excessive weight is applied, or when the rubber becomes old and brittle.
Other creative uses of materials include the seat cushions - which eschew standard stapled or nailed upholstery. Instead the cushions are sewn with a zipper around the outer edge that connects them to a stiff plastic backing. The backing affixes to the plywood shells with a series of hidden clips and rings. This design, along with the hidden shock mounts in the armrest allow the outside veneer of the chair to be unmarred by screws or bolts. The chair has a low seat which is permanently fixed at a recline. The seat of the chair swivels on a cast aluminum base, with glides that are threaded so that the chair may remain level.
...When it was first made Ray Eames remarked in a letter to Charles that the chair looked "comfortable and un-designy" (sic). Charles's vision was for a chair with "the warm, receptive look of a well-used first baseman's mitt.
"Since the very public employees they continually criticize are now their owners, we strongly believe that those who currently run the editorial pages should be replaced," Weber wrote in a March 26 letter to Platinum CEO Tom Gores.L.A. police union wants San Diego newspaper writers fired (Thanks, Doran!)Weber, in an interview, emphasized that the League is not demanding changes in the paper's news coverage of the issue or in its staff of reporters. "It's just these people on the opinion side. There is not even an attempt to be even-handed. They're one step away from saying, 'these public employees are parasites,' " Weber said.

Some time last year, there was a bunch of news about how VCR tapes would no longer be manufactured. Around the same time I noticed that none of the VCRs showing up at the dump had digital tuners. Wouldn't it have been nice if those manufacturers could have dropped in a little extra circuit board to extend the life of their hardware? Even the ones with tape and DVD don't have digital tuners. Go figure. So it serves them right that now all this hardware ends up being excellent project fodder!
This looks like it would be a great school project to examine the design process. Anybody up for trying it in their classroom?
In a very short time, this video lays out the concept, shows how to get started, explains that you should save certain things, details a little of the construction, and leaves the specific details to the creative minds of the people doing the project. There are a lot of ways that we could go at this project, lights, sound, counters, programming. Do your stuff and show it off in the MAKE Flickr pool!
[Thanks, Norm!]
