Nokia has been struggling a bit this year, but this "hack it" to get your phone unboxing is pretty interesting. Once you "root" the box it opens up and a little puff of smoke appears, along with your phone (if you're a phone / gadget reviewer). It's interesting to see what's been happening on the artist/maker side of phone hacking, a couple years ago the Nokias were all used for projects - and then the iPhone came out and almost immediately the very same folks were jailbreaking and then making their own apps. There's still not a lot of hardware interaction, but the iPhone seems to be the phone of choice for hackin' around oddly enough.
Mike Rotondo created an instrument using an Arduino, Max/MSP and some sensors for a Physical Interaction Design workshop at Stanford's CCRMA. As he puts it: "When the guitar is too sexy and the piano makes too much sense, it's time to stick a bunch of sensors to your body with electrical tape and plug it all into your computer!"
How it works:
There's a small electret microphone attached to my foot, and two bend sensors on my arm: one in my elbow, and one on my finger. The signals from each of these are routed through an Arduino microcontroller into a Max/MSP patch.
The microphone output is routed through a percussion follower, and impulses (like stomps) trigger the instrument's tone generation. The sound of the instrument is created by a a plucked string model and some ADSR'd harmonized sine waves. If the impulse picked up by the mic is heavy in high frequencies, the sound is captured and "granulated" around a bit at a random interval.
China is home to a widespread DIY culture fed by necessity (the mother of all invention) and innovation. These garage builders and innovators are, like their products, often called shanzhai. Literally translated, it means "mountain strongholds," but it has come to mean nonprofessional or clandestine manufacturers turning out products from the basic to the highly sophisticated. These shanzhai often take familiar products, concepts and marketing memes and remake them with peculiar but innovative twists.
Aviation is by no means an exception, and it has its share of shanzhai builders. But there is more to it than that. China's emerging aviator class is spreading its wings with a plethora of approaches, from the ramshackle to the sophisticated to the potentially revolutionary. They're using everything imaginable, from old motorcycle engines to electric motors to even their own legs, like Mao Yiqing and his human-powered airplane shown above. You could easily plot these adventurous innovators on a graph, with the X axis showing their skill and the Y axis their financial means.
Back in July, I blogged about YB2Normal's inexpensive PVC gimbal for a home-made steadicam rig. Since that time, William has been steadily refining his design. Version five, pictured above, features a redesigned gimbal incorporating an off-the-shelf auto part. [via Hack A Day]
Youtube user Brusspup made these animated optical illusions by carefully combining slices of different drawings, then sliding an image of vertical lines over the top. That part is straightforward. The illusion comes in when your brain interprets the small white slits that it sees into larger shapes. He also has a nice tutorial on the technique:
I can understand doing this by hand to learn how this works, but it seems like the perfect kind of task to automate with a computer program. Anyone up to the challenge? [via laughing squid]
After months of searching for a new home for a full-scale model of the space shuttle's crew compartment, Chuck Ryan is beginning to accept the replica he spent almost 15 years building may soon be destroyed.
He is now trying to find takers for 1,000 toggle switches, 50 gallons of paint, 40 gallons of fiberglass resin, plywood, tools and other never-used materials.
"I'm still holding out a little bit of hope that someone wants the shuttle," said Ryan, who would like to donate the 33-foot long, 10-ton model and see it used as a monument or for a space camp.
Ever wonder how you can get rectangular lumber from round trees? I figured that it involved a lot of sawing, but didn't realize how much handling was required. The video above is of the Jackson Lumber Harvester 3 Saw Vertical Edger. [via core77]
Every other week, MAKE's awesome interns tell about the projects they're building in the Make: Labs, the trouble they've gotten into, and what they'll make next.

There aren't many low-budget ways to customize one's yo-yo. The most common ones are either painting or dyeing, but they're limited: paint chips off with time, and dyeing is only for plastic yo-yos.
Being a yo-yo fanatic, I regularly visit the blog yoyoskills.com for yo-yo news. There I recently read a post about spin-activated LED side caps that fit into the side of yo-yos. They're low-cost ($6) and look very cool; a perfect customizing add-on for a yo-yo. Unfortunately, they only come in one size, thus only fitting a few yo-yos.
I thought it'd be a fun project to make my own set (and it was!). I used a One Drop Project yo-yo.
How It Works Using the centrifugal force generated by the spinning of the yo-yo, the spring, acting as the switch, is pulled outward. It makes contact with the positive leads of the LEDs, thus completing the circuit, turning the LEDs on.
It looks great in action, day or night. Check out the video:
I'll be writing up the project as a DIY article soon. Look for it in MAKE Volume 22 this spring.
Interesting tutorial over on Propnomicon, by Richard Bird, who built this vintage diving helmet replica prop for a recent LARP adventure for London's The Dark Door group.
Make: Online guest contributor and all-around pal Paul Overton, of Dude Craft fame, has kindly solicited an article from me for his new creative-process blog Make & Meaning. My piece is called On The Care and Feeding of Ideas. Thanks, Paul!
The same technique used for Thom's face in the Radiohead "House of Cards" video. I'll walk you through setting up your projector and camera, and capturing images that can be decoded into a 3D point cloud using a Processing application. Most 3D scanning is based on triangulation (the exception being time-of-flight systems like Microsoft's "Natal "). Triangulation works on the basic trigonometric principle of taking three measurements of a triangle and using those to recover the remaining measurements
Evil Mad Scientist Labs posted a thorough update to their accelerometer tutorial using ADXL335 breakout board, ATMega168 chip, and LEDs as indicators -
The big idea is that when there is no acceleration in (say) the X-axis direction, both X-axis LEDs are off. When it detects acceleration one way, the red LED lights up (and brighter, the higher the acceleration is) and it lights up blue for acceleration in the opposite direction. (Naturally, the other two axes work the same way.)
The full step-by-step + source code can be found on EMSL's site.
Mark Demers shows off the latest from Spikenzie Labs, Four in a line - a laser-cut Connect Four style game which looks a heckuva lot slicker than its retail counterpart.
I've always been a last minute Christmas shopper and it has usually worked out. This year I had a request to get a Connect Four game, but I couldn't find it in stock anywhere. So I decided to make my own version of it.
After working like one of Santa's Elfs for a few hours (minus the green tights) I had beautiful Connect Four style game.
The project's design files can be found over at Thingiverse
