Every week, Limor and Phil from adafruit industries do a Ustreamed "Ask an engineer" live chat. This week, tonight, they're going to do it from Maker Faire Rhode Island. Here's what they said on their site:
Tonight is our weekly "Ask an engineer" live chat - 10pm ET tonight, we're going to attempt to "broadcast" LIVE from Maker Faire Rhode Island. We'll see how it goes, we might need to go text only if there isn't a good connection. Either way - stop by! Here are some handy details:* Visit our new "chat" section on Adafruit at 10pm ET - 9/19/2009
* Or visit our Ustream page
* For old schoolers, you can use IRC, you'll need a Ustream log/pass, check out the Ustream IRC how-tos here and here
* We are #adafruit-industries6796 on IRC server chat1.ustream.tv
* There will be a trivia question at the end of the night as always!
* Lastly, if anyone can save a log we'd appreciate it

The last time we covered this neat die reading machine by Steve Hoefer, he had a very nice design that was starting to be able to determine the number of a die placed on it. Well, he swapped out his problematic photoresistor sensors for an infrared emitter/detector-based scheme to produce version 2, which he claims works with almost perfect accuracy. Another feature he added is to display the complement of the sensed number, so that the display shows the same number as the top of the die.
I find this project especially interesting because of the homemade sensing apparatus. Instead of going with a full-blown computer vision system to solve this problem, he used a bunch of simple sensors in a creative way, and was able to build the whole thing using a low-power microcontroller. In fact, his solution reduces the problem so well, that even the microcontroller could be eschewed for a straightforward set of logic gates. Anyone up for that project?
Challenge: Steve determined that he needs to look at five 'pip' (black dot) locations to uniquely identify each number. Can you explain why? Are there any other arrangements of five sensors that could work? Remember that each number could physically be rotated to four different positions, and you need to detect it no matter how it is stuck in. Answer on Monday.

There seems to be much progress on the DNS project I asked for a couple of days ago. Two or three developers seem to be approaching the point of deploying and the APIs probably are pretty close. I hope that when they surface we can try to get the APIs into agreement. The differences appear to be cosmetic.

If you're a Lovecraft fan and have not yet seen the HPLHS's 2005 silent-film adaptation of Call of Cthulhu, well, there may be nothing, anywhere, that's more important than that you go do so immediately. So. Very. Good. The look they achieve on a low budget is amazing, and a lot of that is due to the outstanding props, including several awesome Cthulhu idols, many of which are available in reproduction. But the art deco "LeGrasse" idol shown here is my favorite.

Today is Rosh Hashanah, the Jewish New Year.
Let's hope it's a sweet one! No better way to kick it off then with this sweet classic from Moishe Oysher and the Barry Sisters, Halevai.
What a tour de force! Check Oysher's vocal gymnastics as he bounces off of the Barry Sisters' harmonies! He coulda been one hell of a freestyle rapper...

Tanner of Noystoise demos a rather sweet little synth he's housed inside of what appears to be an alarm clock's former enclosure -
mini keyboard heavily modified to make synthesizer sounds. frequency divider triggers an envelope generator that modulates the vcf with resonance at 1/256? of the vco. the vco is divided in 1/2, 1/4, 1/8 and mixed to the vcf. 1/32,1/64, 1/128 of the vco also modulates the frequency of the vco(pitch) and generates some pretty random voices.This piece is just the tip of the iceburg - for more, be sure to hit up the NoysToise blog.

After exploring the innards of our CD drives, students in my robotics class are coming up with some clever junkbots. Here are a few of the first ones, more to come as they evolve. In both cases, by the end of the period, these student designed and made devices had been improved before the period ended.
As the school year begins, how do you help students understand the basics of electricity, manufacturing, and creating original devices? As a student, what are the best projects for the start of the semester or school year to get you excited to go deep and learn more?

Starting with the blueprints printed at full scale (HUGE) I made cross sections out of insulation foam and glued them into place. The empty areas between sections were filled with cardboard. This formed what I called the "skeleton" of the body. The empty cavities in the skeleton were then filled in with expanding foam. After drying, the foam was carved into the shape of the main body. After this was completed (and the foam given more drying time so it would retain its shape) the entire form was covered in stretch fabric. This smoothed out a lot of the lumpiness of the foam.
The nation's leading journalism schools come together in this unique program to experiment with new forms of in-depth and investigative reporting.News21 | Carnegie-Knight Initiative on the Future of Journalism Education (Thanks, Dan!)Students travel the country to report on critical issues facing our changing nation and then find innovative ways to tell those stories.

Historically, when the new communication device comes out, the reaction tends to be divided. Some people think it's the best thing since sliced bread; other people fear it as the end of civilization as we know it. And most people take a wait and see attitude. And if it does something that they're interested in, they pick up on it, if it doesn't, they don't buy into it.Is the Internet melting our brains?I start with Plato's critique of writing where he says that if we depend on writing, we will lose the ability to remember things. Our memory will become weak. And he also criticizes writing because the written text is not interactive in the way spoken communication is. He also says that written words are essentially shadows of the things they represent. They're not the thing itself. Of course we remember all this because Plato wrote it down -- the ultimate irony.
We hear a thousand objections of this sort throughout history: Thoreau objecting to the telegraph, because even though it speeds things up, people won't have anything to say to one another. Then we have Samuel Morse, who invents the telegraph, objecting to the telephone because nothing important is ever going to be done over the telephone because there's no way to preserve or record a phone conversation. There were complaints about typewriters making writing too mechanical, too distant -- it disconnects the author from the words. That a pen and pencil connects you more directly with the page. And then with the computer, you have the whole range of "this is going to revolutionize everything" versus "this is going to destroy everything."

Interesting article about the "Right-to-repair bill"....
The federal “cash for clunkers” program succeeded in bringing customers back to new car lots after a long absence, but most people are still driving the car they had. Increasingly they are driving to their local mechanics to make sure those cars last even longer.
That is good news for the independent automotive repair industry because car owners are now willing to spend their money on repair work rather than take on new car payments, and they are saving on those repairs at independent shops.
But while consumers appear content to keep their older cars on the road, they are increasingly discovering that their car’s computerized systems may be conspiring to force them to turn to more expensive dealer repair shops even when those cars are out of warranty.
Most consumers experience this when they see a ‘check engine’ light or another warning that suddenly appears on their dashboard. When they bring it into independent (non-dealer) shops like ours, they simply want the underlying problem fixed so that pesky light goes off.
Sometimes, however, we can’t shut off that light even when we can make the underlying repair.
Most legislation on Beacon Hill is controversial and ultimately difficult to decipher, but Right to Repair is straightforward: You own your car and you should have the right to choose where it gets repaired and not be forced back to dealer mechanics.Read more | Permalink | Comments | Read more articles in Transportation | Digg this!
House Bill 228 and Senate Bill 124 are controversial only because car manufacturers don’t want car owners to have unfettered access to their own repair information and are fighting it vigorously. That alone should flash a warning light for legislators and consumers that might read: Check Manufacturer’s Motives Now.
Almost every form of publishing has been organized as if the medium was what they were selling, and the content was irrelevant. Book publishers, for example, set prices based on the cost of producing and distributing books. They treat the words printed in the book the same way a textile manufacturer treats the patterns printed on its fabrics.He goes on to explore how this applies to music, movies, books, newspapers and software. From there, he comes to the same conclusion many of us have been discussing for years:
Economically, the print media are in the business of marking up paper. We can all imagine an old-style editor getting a scoop and saying "this will sell a lot of papers!" Cross out that final S and you're describing their business model. The reason they make less money now is that people don't need as much paper.
What happens to publishing if you can't sell content? You have two choices: give it away and make money from it indirectly, or find ways to embody it in things people will pay for.Good stuff and worth reading the whole thing, though I think he misses one key important ingredient. If you take a step back and look at the overall economics of such markets, you quickly realize how much bigger they get when you free the content from the constraints and scarcity of physical media. This is the hardest part for some people to see, at times, but the key to recognizing it is realizing that the content itself is a resource, rather than a final product, and you've just increased the availability and massively decreased the cost of that resource -- and you can then use it (for free!) to make many other things more valuable. That, in a nutshell, is the most exciting part about freeing up digital content.
The first is probably the future of most current media. Give music away and make money from concerts and t-shirts. Publish articles for free and make money from one of a dozen permutations of advertising. Both publishers and investors are down on advertising at the moment, but it has more potential than they realize.
I'm not claiming that potential will be realized by the existing players. The optimal ways to make money from the written word probably require different words written by different people.
Above, Jude Law in fab drag. A still from the forthcoming feature Rage, directed by Sally Potter, in which Law plays a female model named "Minx." The short version: A young student uses his phonecam to shoot interviews with the staff of a New York fashion house, and posts them online without the interviewees' knowledge or consent. A runway accident turns into a murder investigation, then, "denial leads to devastation." Here's a New York Times piece about the film, by Guy Trebay.

Here's what DPA, Germany's national news wire reported this past September 11th 10th:
A terrorist attack occurred in the city of Bluewater, California. The suicide bombers were German rappers, the "Berlin Boys".
A half hour later DPA issued a correction: there had been no bombing. The "Berlin Boys" are not a rap group. The city of Bluewater does not exist.
It was all an elaborate publicity stunt to promote the satirical German film Short Cut to Hollywood. Filmmaker Jan Henrik Stahlberg and his team fooled their entire nation by creating fake websites and videos:
