Gather a group of potentially bored kids in an open space with tools and a heap of sawmill scraps, add summer vacation and what do you have? Hutopolis!
A village of eight huts was constructed during two weeks in July from timber slabs from an area sawmill, salvaged wood and found items. Each hut is different, based on the children's design, with odd angles and shapes, rooftop lookout posts, windows, doors, ladders and a fire pit under a homemade shelter in the village center.

Rob Nero is building this interesting finger tracking device using two infrared lasers and 110 infrared sensors. The cool part about this is that all the math is being done on the microcontroller, which means that it can be used without hooking it to a computer. He writes:
When 2 shadows are detected (one by each laser), it calculates the XY coordinate of each shadow. Using simple algebra, I will be able to calculate the equation for each line that is created (between laser and shadow), and then find where the 2 lines intersect (where my finger is).
There are some more videos at his Vimeo channel. [via Arduino Blog]

Back in the day before ARIN, I obtained a class C license (255 IP numbers) for a network of servers running in my garage. This block hasn't been in official routing for several years. As you well know, class C licenses are in rather short supply.This is a unique situation. I was talking couple of years ago about this with Clay Shirky, who suggested I crowdsource the question, so here goes:
What's the most creative use that you could imagine for an IP v4 class C license?
A couple weeks back, I blogged about how much my daughter and I were enjoying the old Betty Boop cartoons on Archive.org, which feature the likes of Cab Calloway and fantastic incidental and theme music by Sammy Timberg, who also wrote music fo Popeye, Superman, and other Max Fleischer cartoons.
A commenter mentioned that Timberg's daughter Pat Timberg had recorded and released a CD of Sammy Timberg's Max Fleischer classics called "Boop-Oop-a-Dooin'," and Pat was kind enough to send me a review copy. We've been playing it around the house for a couple weeks now and again, the kid and I have been totally rockin' out. I love hearing some of my favorite Popeye songs, like "Clean Shaven Man" as well as Flesicher classics like "An Elephant Never Forgets" and, of course, Betty Boop's flirty, silly little songs.
The vocals, provided by Timberg's granddaughter Shannon Cullem and Richard "Mr Tin Pan Alley" Halpern are spot-on versions of Popeye, Wimpy, Olive Oyl, Betty Boop and the other Fleischer favorites. The orchestration is lively and sprightly, and my daughter, who's just starting to sing and speak, loves the songs as much as I do.

Mark has an example of what designers used to have to do in the days before desktop publishing... via textfiles.

Teach your family to solder! Take a few pictures tagged as "MAKEcation" and put them in the MAKE Flickr pool by September 9th to enter to win a $100 Maker Shed gift certifiate!

If you are looking to introduce soldering to your classes this school year, you should consider having students use a soldering vise or other holder to secure the circuit board. Keeping the components in place will help students get the hang of soldering quicker than if the board and parts are loose on the table or held by hand. I've been messing with this idea more since using the PanaVise my brother employed to solder the boards for his HeathKit amateur radio back in the day. While super nice to use, a well-made vise like this is too expensive and too easily broken for classroom use. This design can be easily made from readily available supplies from the supply cabinet and a few pieces from either maintenance or home.
My first iteration of the design was pretty simple, a scrap of 1"x3" strapping placed onto a scrap of 3/4" plywood. On the strapping, I screwed down a binder clip with a washer to help the sheet rock screw hold down the handle of the clip. I had some ideas of using water bottles from the recycling bin to hold parts, but plastic near hot iron is a bad combination. There were a few problems with the design, so I made another run at it. The idea behind this project is to create a functional tool, which should be something that kids could make themselves for use at home, or a teacher could bang out a bunch of them pretty quickly and inexpensively to set up several soldering stations.
Skills in this project (you can pick which ones you want to focus on):
Extensions
Storage
You may want to screw a mint tin or two on the board. This will allow you to hold things like short lengths of desoldering braid, solder, LEDs, switches, resistors etc. You will need screws that are at least 1/8" shorter than the thickness of the wood you are screwing into.
Soldering iron holder
You could make an iron holder with a 3/4" screw eye on the side of the upright. Making sure the heat from the business end of the iron is shielded should be part of your design, this could probably be done with a soda can, which can be cut with scissors and held with a short screw or two.
Soldering iron cleaner
Brass or copper pot scrubbers make good tip cleaners. Use a short screw with a wide fender washer (small hole, wide disk) to secure it to the plywood. Steel wool should not be used for a couple of reasons, apparently it scratches up the tip of the iron, and sooner or later, kids will discover that it is flammable, which could invite a visit from the local fire department or its' representatives.
Computer Aided Design
You can introduce students to the powerful ideas around CAD by having them make a virtual model of the stand either before or after building.
For well under $5, you can have a soldering station for your students to hold their work. If they use this as a way to also learn about manufacturing and computer aided design, you can wake up some other useful interests as they get ready to explore electronics.

7 years ago today: "Tomorrow is Day 70 of No Smoking Dave. Ten weeks. A non-smoking story at the Bowie concert last week. As I'm walking out I see people lighting up everywhere. Smell of smoke all around. It smells good. I really want one. In my mind I outline the steps it would take to be smoking and the amount of time it would take. I would ask someone if they could spare a cigarette. If they said no I'd offer them $1. Oh hell, just offer $1 to begin with. Whoo, where would I get a match. I'd ask for a light. Take a drag. Estimated time, 15 seconds to one minute to first nicotine rush. My heart started beating faster. I felt scared like you feel on a NY subway platform as a train is entering the station and you're standing on the platform and in the instant before it passes you think how you could end your life by leaning forward. I never actually jump, and that night I didn't smoke, and it's good that inside I equate smoking with death so deeply that it invokes my subway nightmare. Do I have it beat? No way. I am still an addict, I expect I will be for life. But I'm an addict in recovery, who is not taking the drug. Even better, I am becoming a constant evangelist for a nicotine-free lifestyle for nicotine addicts, illustrating the old adage that you teach what you most need to learn."

BudgetTravel has a slide show of what they've deemed the "World's Weirdest Hotels." No Madonna Inn, but more interesting to me than theme rooms anyway are places where the entire hotel structure is an oddity. Top, the Hotel Costa Verde near Quepos, Costa Rica. Left, at the Capsule Hotel in Den Haag, Netherlands, you can sleep in an escape pod from a 1970s oil rig.

Gijs Gieskes' Synth Car V3 seems like its straight outta crazytown! The R/C rover incorporates a collection of motion sensors to generate sound and even trigger glitches on a circuit bent camcorder. Seen above is the resulting video captured by the onboard cam, providing a view of the pinwheel which generates a clock signal for the sequencer which triggers the Gakken SX-150 synth which … well, the list goes on and on. Take a closer look at some more of the built-in kinetic triggers (box of marbles, etc) over on the project's page - oh and don't forget the earlier versions -

However, this situation changed dramatically in the spring and summer of 2009 with the advent of the Obama administration making public statements about sharing technology related to energy. In reaction, the United States Chamber of Commerce, a leading lobby representing businesses, is expressing growing concern that moves to spread new energy technologies to developing countries could erode the IP rights that have driven commercial efforts to innovate for generations.Such an effort could certainly help advance some of the important scientific research and innovation in clean tech issues... but of course, this new lobby is having none of it:
Late in May 2009, the group and representatives of General Electric, Microsoft and Sunrise Solar gathered in Washington to launch the Innovation, Development & Employment Alliance, or I.D.E.A. The initiative is aimed at pressing Congress and the Obama administration to ensure that global climate-treaty talks do not weaken protections on who can profit from new technologies that provide abundant energy without abundant pollution. The creation of I.D.E.A. has been widely noted, with some alarm, in the IP "watchers" community, and likely means the status of alternative energy as a less-observed IP sector is finished for good....
The new Secretary of Energy, Steven Chu, a Nobel Prize winner, has publicly supported collaborating with developing countries - in particular China - and sharing all IP rights of the resulting technologies. He has already pushed forward with a new U.S.-China Clean Energy Research Center, developed with $15 million dollars each from the U.S. and Chinese governments, and designed to create innovative technologies for building energy efficiency, clean coal (including carbon capture and storage) and clean vehicles. In addition, Secretary Chu is advocating for the development of open-source building energy-efficiency software that will make it cheaper and easier for developers to implement energy saving measures in new buildings, both in the U.S. and in emerging economies like China and India.
In reaction, I.D.E.A.'s first act was to back the Larsen-Kirk Amendment to the Foreign Relations Authorization Act (H.R. 2410). The amendment calls on the President, the Secretary of State and the Permanent Representative of the United States to the United Nations to uphold the existing international legal requirements for IP rights and avoid any weakening of them for the UNFCCC in the context of energy and environmental technology. The Amendment passed the House with a 432-0 vote. It was described as an amendment to protect U.S. green jobs and U.S. technology innovation.Of course, the reality is exactly the opposite. If we don't make the necessary innovation breakthroughs then there won't be that many US green jobs at all. It's stunning in this day and age that politicians can still be convinced that such protectionist policies protect jobs rather than limit them. Getting serious innovation in the clean tech market will create tremendous job opportunities. Focusing on who gets to own the patents (and blocking foreign collaboration) at this stage only delays the ability for the US to create those jobs and to move to better energy options.

"Launchcast listeners do not even enjoy the limited predictability that once graced the AM airwaves on weekends in America when 'special requests' represented love-struck adolescents' attempts to communicate their feelings to 'that special friend'."
Proponents seem to be blind to the systemic impotence of such an identification card scheme. Individuals originally motivated to obtain and use fake IDs will instead use fake identity documents to procure "real" drivers' licenses. PASS ID creates new risks -- it calls for the scanning and storage of copies of applicants' identity documents (birth certificates, visas, etc.). These documents will be stored in databases that will become leaky honeypots of sensitive personal data, prime targets for malicious identity thieves or otherwise accessible by individuals authorized to obtain documents from the database. Despite some alterations to the scheme, PASS ID is still bad for privacy in many of the same ways the REAL ID was.But why let that stop the gov't from coming up with more ways to keep tabs on you?
