Arthritis-Busting Clothespin is Ingenious and Complex

producttank_clothespeg_02

You know when you first wake up in the morning and you’re as weak as a kitten? You try to pick up something small and heavy, but you just can’t grip it. Imagine being like that all the time, only with added pain. That’s arthritis.

Arthritis makes everyday tasks a chore, and we have featured several helpful widgets designed to make life easier for those with gnarled knuckles. This redesigned clothespin, designed by a gentleman only known as Product Tank, wins for being both the most mechanically fascinating, and because it adds many layers of complexity to what is one of the simplest products you can buy.

The peg combines levers, weak springs and a clever rubber-ratcheting jaw to make it both easy to squeeze open and secure in its grip. Squeezing it, like you’d squeeze a hand-grenade before throwing, opens the jaws and lets you slip it over the damp clothes and washing-line. When you let go, the ratchet drops over the front handle and keeps it in place, and the spring pushes it forward as far as it will go.

If the pin slips then the rubber grip will push the clamp further closed. But no matter how tight it gets, a light squeeze on the rear handle will pop it open and relieve the pressure. It sure is ingenious but, like I said, it is also way more complex. Then again, even tripling the price of a pack of clothespins is still cheap.

Product Tank tried out an array of prototypes on his arthritic neighbor Shirley before arriving at this final design. Here’s hoping that this one makes it out of Shirley’s back yard and into stores. Video below (skip to two minutes in).

EVO 4G Hacked, Rooted Before Arriving in Stores

Google’s gift to attendees of its I/O conference last week was the hot new HTC EVO 4G cellphone. One of the lucky giftees was developer Matthew Mastracci, who showed his gratitude by teaming up with two friends and hacking the hell out of the poor little EVO.

A few hours later and the team had successfully rooted the phone, and “managed to get the standard su tool installed.” This means that they had root, or super-user access to the phone and its file system. This lets you do anything you like to it. Here’s the video:

What does this mean for security? Not much. If you have physical access and a little time, you can hack pretty much any device. More interesting is the reminder that the new wave of smartphones – Android and iPhone – both use variants of the UNIX operating system under the hood, first developed way back in 1969. That these modern pocket miracles are running on an OS invented before I was born still kind of blows my mind.

Crowds Embrace DIY Spirit at Fifth Annual Maker Faire

Maker Faire

Is do-it-yourself culture going mainstream?

Just ask the tens of thousands of people who are expected to cram into the San Mateo County fairgrounds this weekend for the fifth annual Maker Faire Bay Area. They’ll munch on corndogs and funnel cakes, swill $8 plastic cups of beer, and watch as artists, hobbyists and tinkerers show off their creations of steel, electronics, fabric and fire.

makerfaireMaker Faire — sort of a combination science fair / county fair, with a hefty dose of Burning Man thrown in — has been happening once a year in this suburb on the outskirts of Silicon Valley since 2006. The first Faire drew about 20,000 attendees and 200 exhibits, and both of those figures doubled the following year. Now, with 70,000 attendees expected and exactly 600 exhibits, the Maker Faire is starting to feel a little, well, crowded.

In the past several years it’s expanded to other locations, too. Regional Maker Faires will be held in Detroit July 31 to August 1 of this year and in New York September 25 to 26.

Dale Dougherty, the executive director of Maker Faire and the founder and publisher of Make magazine, says that, far from watering down its DIY ethos, the fair’s growth is a good thing.

“We’re able to reach more people. We’re able to include more diverse styles of making, coming from different communities,” Dougherty says. “I wouldn’t say this is mainstream, but people don’t think of it as quite the oddity it may have been in its first year.”

As the Maker Faire has grown, it has created business opportunities for the do-it-yourselfers who are its core. Burning Man crews like the kid- and crowd-pleasing Electric Giraffe Project show off their creations while selling bumper stickers to help defray their costs. Makers display their electronic creations and sell kits so you can make the same gadgets at home — or sell you the finished product outright. Companies like Rentalic and Sparkfun that cater to do-it-yourselfers hawk their services and kits at the fair.

“If people can make money at Maker Faire by selling their stuff, that’s a great validation of the value of making,” says Mark Frauenfelder, the editor-in-chief of Make magazine.

“It hasn’t become more refined or more commercial,” Frauenfelder says. “It’s always had that kind of homemade — in the best sense of the word — feel.”

But it’s not all buying and selling. Maker Faire is also a chance to connect with other hobbyists, get inspiration about projects you might want to take on, or get advice on the projects you already have underway.

Here’s a taste of what you can see at Maker Faire this year: Do-it-yourself DNA testing, pedal-powered vehicles, flamethrowing robot dragons, an extra-large recreation of the “Mousetrap” game, and lots and lots of LEDs.

Kyle Wiens, CEO of gadget-repair site iFixit, says his company will be there, with about 30 volunteers helping teach people how to fix their gadgets.

“Making and repair are yin and yang,” says Wiens.

Some go because they want their children to see the creative possibilities of making everything from robots and LED toys to sewing projects and crafts.

“I take my daughters because they are interested and find creation fascinating,” says Scott Cleaveland.

And others go just because they enjoy connecting with other makers. For instance, Rick Washburn, a “muffin car” maker who lives in Redwood City, California, says he spent his childhood assembling inventions out of discarded gadgets left out on big trash day.

“The Maker Fair is like a big class reunion of grown-up kids who did the same thing,” says Washburn. “We bring our creations to the Maker Faire so we can show off and enjoy our creations together.”

What to Do at Maker Faire

With more than 600 exhibits and dozens of presentations, performances and events, it’s hard to know what to do at Maker Faire. Check the Maker Faire event schedule for a full rundown, and see below for some highlights of the two-day event.

Expect crowds: Parking lots will fill up early, so take public transit or bike, if you can (the Faire is offering free valet parking for up to 2,000 bicycles).

Here are some highlights you won’t want to miss.

Makerbot Industries will show off its inexpensive 3-D fabrication machine, the Makerbot, at 11:30 and 2:30 p.m. on Saturday.

Mythbusters co-host Adam Savage will be speaking at 2 p.m. on Saturday. He’s a dynamic presenter, and a folk hero to the DIY crowd, so this should be a fun event.

Remember that Diet Coke and Mentos fountain video from a couple of years ago? The guys that created the video, Eepybird, will be recreating their show at 1 p.m. and 4 p.m. Saturday, and at 4 p.m. Sunday.

Ford is using Maker Faire to announce its latest automotive technology platform and talk about how your gadgets can interface with it. Ford R&D engineering executive K. Venkatesh Prasad will be talking about “Automakers 2.0″ at 3 p.m. on Saturday.

Pop band OK Go will give a performance on Sunday evening. The group’s amazing Rube Goldberg video debuted earlier this year, and their show will probably involve some gadgety, DIY surprises from exhibitors at the show.

Wired editor-in-chief Chris Anderson will talk about building autonomous drones at 5 p.m. Saturday and 4:30 p.m. Sunday.

Wired contributor Ken Denmead will be speaking at 3 p.m. Saturday, talking about GeekDads and GeekMoms and “how to bring out the geek in your children.”

3-D Goes DIY With Amateur Photos, Videos

4006017680_d1eb5f534f_b

After the blockbuster hit Avatar, 3-D movies are all the rage in Hollywood. But 3-D’s no longer the playground of big studios.

3-D photography and video are catching on among shutterbugs and independent filmmakers. These intrepid experimenters are rigging up cameras and using software tricks to produce short films, home videos, note cards and photos that seem almost Harry Potter-esque in the way the subjects wave and pop out of the page.

“What you are finding in the DIY community is that there’s a lot of experimentation with the language of 3-D and what it can do,” says Eric Kurland, a 3-D photography enthusiast who’s also the vice president of the Stereo Club of Southern California. “The studios are primarily focusing on children’s movies, or flagship tent-pole action movies, but we are doing a lot more.”

makerfaire

Kurland and other 3-D photography enthusiasts will be giving a how-to presentation at the fifth annual Maker Faire Bay Area, which will be held Saturday and Sunday, May 22 and 23, in San Mateo, California. The annual event, put on by O’Reilly Media, is a celebration of DIY culture, arts and crafts, and will likely draw more than 70,000 attendees, organizers say. Kurland and other 3-D enthusiasts will be showing a home-brewed stereoscopic camera, displays, 3-D video and photos.

The 3-D format is making a big comeback this year. Hollywood has been flooding theaters with 3-D movies such as Avatar, Up, Alice in Wonderland and Clash of the Titans. 3-D TVs were one of the biggest stars of the Consumer Electronics Show this year. Almost every major TV maker including Sony, LG, Panasonic and Mitsubishi plans to offer big screen 3-D TVs this year. TV channels such as ESPN and Discovery have promised 3-D channels that will begin broadcasting early next year.

But it’s amateur content that could be the real catalyst for 3-D’s popularity.  In a sign that homemade 3-D videos could soon be ready to hit mainstream, YouTube has started offering a 3-D display option.

“Personal content could be a very under-appreciated part of driving 3-D technology ,” says Kuk Yi, managing partner for the venture capital arm of Best Buy. “Being able to see your own content in 3-D has a strong emotional pull.”

Yi says the most impressive 3-D demo he’s seen so far used two jury-rigged cameras that shot a clip of someone having coffee.

“It was more impactful for me than all the sports 3-D demos,” he says.

There’s not a whole lot of professional hardware available for home 3-D enthusiasts. Major electronics makers are peddling cameras to Hollywood or professional cinematographers, and there aren’t a lot of ready-to-use options for ordinary folks who want to make 3-D imagery.

“I don’t think anyone’s caught on to doing something like a Flip for 3-D,” says Yi. “It’s a market right for innovation and disruption.”

Last year, Fuji released the first 3-D point-and-shoot digital camera, a $600 gadget that’s still mostly available in Japan.

But for DIYers, the lack of off-the-shelf equipment is a call to action.

MacGyvering 3-D Cameras

Videos and photos shot in 3-D trick our brain to perceive depth. Our eyes are about three inches apart, which means each eye sees a slightly different perspective of the same scene. The brain takes images from both eyes and uses the difference between them to calculate distances, creating a sense of depth.

To make a 3-D image, you need to rig two cameras together so each shoots the same scene from a slightly different  perspective. Then, you use software and 3-D glasses to look at the images on your screen, recreating the visual field created by the two cameras.

For those willing to experiment, everything from two iPod Nanos or two Flip camcorders hooked together can become a 3-D camera rig. Kurland used off-the-shelf hardware and parts scavenged from other camera mounts to build a rig for himself.

“I have a flash mounting bar that lets me attach two cameras and vary the distance between the two cameras,” he says.

You don’t necessarily need a two-camera rig, says Barry Rothstein, who’s written four  books on the art of 3-D photography and sells 3-D notecards. With a single camera, he says, you have to first take the left-eye picture and then slide the camera about 2.5 inches to the right for the right-eye picture. There are limitations to the technique: It works best with a tripod, and still life shots are pretty much all you can do, since you need a subject that will hold still while you move the camera.

The magic of 3-D lies in the post-production.

A freeware program called Stereo Movie Maker has become the de facto software for 3-D enthusiasts. The software works only with PCs but it can correct alignments so the two photos of a frame are perfectly positioned.

Watching 3-D photos or video is possible with the classic red-cyan glasses. YouTube’s 3-D player also offers options compatible with different types of glasses, depending on what kind of display you’re using.

“I love 3-D photography because it is fascinating and when you get a really good image, it gives you much more than a regular photo,” says Rothstein. “The response I get from people to 3-D photos is remarkable.”

Rothstein says he’s shot photos of a family dog for a special Christmas card and helped create wedding invites based on a 3-D photo.

It’s a sign that 3-D isn’t a fringe movement anymore, say Rothstein and Kurland.

“It used to be that 3-D was something people remembered but didn’t think that much about, but in the last year there’s just been a big change,” says Kurland. “There’s a new respect for the DIY community of 3-D photographers that we weren’t seeing before.”

Maker Faire Preview: Electronic Fireflies to Light Up Your Backyard

electronic-firefly

Fireflies in a jar are a wonderful childhood memory for many of us. Not surprisingly, it’s one of the things that Tom Padula missed when he moved from the Midwest to Silicon Valley nearly two decades ago.

So in the spirit of Silicon Valley, Padula decided to create electronic fireflies: lightweight, inexpensive, solar-powered bugs. At night, the fireflies flash a light on and off for about two hours, then switch off to recharge in the next day’s sunlight.

“I built about 20 and hung them in the backyard, on branches and bushes,” says Padula. “Bliss.”

About the size of a quarter, the electronic fireflies have a rechargeable battery pack. The batteries are charged each day by six tiny solar cells. At dusk, they come alive with a fading on-and-off pattern.

makerfaire“The slightest breeze moves them around, and the motion combined with the light is mesmerizing,” says Padula, who will be selling his digital lightning bugs for $10 apiece at the fifth annual Maker Faire Bay Area, which will be held this coming Saturday and Sunday, May 22 and 23, in San Mateo, California. The annual event, put on by O’Reilly Media, is a celebration of DIY culture, arts and crafts, and will likely draw more than 70,000 attendees, organizers say.

Padula’s fireflies weigh 0.2 ounces (7 grams) and are attached to an 18-inch monofilament line. Six solar panels charge NiMH batteries, and a microcontroller drives the LED. The units are dipped in epoxy for weather resistance.

“All the real work happens in the code, from determining ambient light level, to controlling the LED intensity and keeping track of how long the pattern has been active so as to turn off after two hours, like real fireflies do,” says Padula.

Originally, Padula assembled each device by hand but now contracts it to a shop in Nevada.

Padula says he initially created the electronic fireflies for his enjoyment but after encouragement from friends and family, he hopes to make a business out of it.

See below for a closer look at the firefly.

Maker Faire Preview: Animatronic Dragon Breathes 8-Foot Fireball

saphira1

Some Christmas family traditions include baking a cake together or going caroling. But Tony DeRose and his family have their own way of doing things.

This year, that involved an animated, fire-breathing robot dragon.

For the last three Christmases, DeRose and his two sons have decided on a project for the coming year. Then they built each one, aiming to complete whatever it is in time for Maker Faire.

This year’s creation was a fire-breathing dragon called Saphira, inspired by a character from the Eragon book series.

“She’s very articulated,” says DeRose, of his dragon. “She can really move her head around and she will be breathing a 8-foot to 9-foot fireball.”

makerfaireSaphira, along with more than 600 exhibits, will be on display at the fifth annual Maker Faire Bay Area, which will be held this coming Saturday and Sunday, May 22 and 23, in San Mateo, California. The annual event, put on by O’Reilly Media, is a celebration of DIY culture, arts and crafts, and will likely draw more than 70,000 attendees, organizers say.

The dragon, built out of parts from the hardware store and online specialty shops, combines pneumatic actuators, flame effects and an Arduino microprocessor to put on a spectacular show.

“We wanted the head to be pretty highly articulated so we wanted it to go up and down, side to side, and we wanted the jaw to be able to open and close,” says DeRose, who works at Pixar Animation. “Designing a mechanism for the head was very tough.”

To get started, DeRose and his sons created pencil sketches of how they wanted the dragon to look. In earlier projects, he says, he has used Google’s Sketch-Up design software, but the dragon’s design and different angles made it easier to draw on paper.

In its crouched position, the dragon will be about 3½ feet high and have a wingspan of about 8½ feet.

Balancing the weight of the finished sculpture will be the biggest challenge, says DeRose. Saphira weighs about 45 pounds.

“It has to be lightweight but strong so it couldn’t wave around too much. The penumatic actuators are light, but once you add tubing, spark plugs and transformers it adds up,” says DeRose.

To control the beast, the team uses a Logitech game joystick connected to a Mac laptop. The Mac is connected to an Arduino board that drives pneumatic solenoid valves using a SN75441 motor controller chip.  For the flame, they use propane gas.

Overall, the project cost him about $1,200. At Maker Faire, DeRose and his family hope to have Saphira breathe a giant ball of fire at least twice every hour.

See below for more photos and a video of Saphira.

Canon AE-1D, The Ultimate Digicam Hack

32206050129_large

This is the Canon AE-1D. No, it’s not Canon’s latest retro-styled DSLR. It is an old Canon film camera hollowed out and stuffed with an Ixus 870 IS. It’s also the best hack I have seen this week.

The Canon AE-1 was a classic. First made in 1976, it went on to sell around 5 million units. It featured manual-everything, with the addition of a shutter-priority mode and an electronically controlled shutter. I never owned one, but I have used plenty, and it was a beautiful old camera.

This mod takes on of those 5 million bodies and makes room for the tiny modern digicam. The shutter is connected to the old mechanical shutter release, the opening film-back is replaced by the LCD screen and buttons, and it appears that the lens has been trimmed somewhat, presumably to prevent vignetting. The hack even adds a hinged hatch in the bottom for replacing the battery. Sadly, the viewfinder has been lost, but the camera has gained a pop-up flash.

Many people like the idea of just dropping a digital sensor into an old film SLR, giving the fantastically intuitive controls of a shutter dial and aperture ring and light, tough body, along with access to lots of old manual lenses. This mod, by an unknown hacker, comes as close as we’re ever likely to get. Now where’s my Dremel? Video below.

iPad-Controlled Blimp Schmoozes With Partygoers

As if anyone besides Apple needed to inflate the hype surrounding the iPad, a digital marketing team jiggered with the tablet to remotely control a homemade 52-inch blimp at an after-party.

To construct the blimp, the BreakfastNY team followed instructions provided by Wired magazine’s Chris Anderson in his blog DIY Drones and added a camera that shot a live feed viewable on the iPad.

For controlling the blimp, the team used Titanium to write the web code and compile it into an iPad app, as well as OpenFramework for the camera software.

“Everyone was really into it,” said Andrew Zolty, a BreakfastNY employee involved in the project. “It kind of brings out the kids in everyone. People would kiss it and do strange things.”

BreakfastNY made the blimp to promote a silent auction for KidRobot Munny characters created by the world’s leading industrial designers. Whenever the blimp’s camera hovered over a person, the iPad software transformed their faces into those of the Munny characters. The feed was displayed on a big screen for all to see. That’s some pretty in-your-face marketing.

Mobile Phone Guitar Makes Sweet Music

mobile-phone-banjoThe Phone Guitar, a project by a Dutch developer, places two Android phones, an iPod Touch and two Windows phones next to each other on a guitar frame and uses apps on the devices to play music.

As the video clip below shows, the developer ‘Steffest’ plays a version of Cracklin Rosie and its not the cacophony you would expect.

The original idea was to create the same mobile app on all three mobile platforms, he says. The app would be a small piano and drum sequencer.

That didn’t quite work out.  “Audio latency is a b*tch and building the app from the same source proved to be possible but unusable,” writes Steffest on his blog. “I ended up writing it three times: in Java for Android, in C# for Windows Mobile and in Objective-C for iPhone.”

Instead what he did was combine his homebrewed app with other programs including the Pocket Stompbox for Windows Mobile that’s good for real time effects. There’s also iShred, an iPhone electric guitar app in the mix.

To play them all at once, he taped them on a piece of wood together with a battery powered speaker.

It’s not all that bad on the ears. Listen to it:

Video: Neo Keyboard Hooked up to iPad

General-purpose devices such as the iPad are rendering a number of dedicated devices unnecessary by replacing them with apps. Rather than toss his word-processing Alphasmart Neo keyboard in the recycling bin, Eolake Stobblehouse had a clever idea: Why not hook up the keyboard to the iPad?

iPad with Neo as keyboard from Eolake Stobblehouse on Vimeo.

In the video above, Stobblehouse shows off his Neo hooked up to the iPad via a USB dongle (the iPad camera connection kit, which, as it turns out, connects to a lot more than just cameras). Much to our surprise, the six-year-old keyboard appears to work.

What’s more, Stobblehouse used paperclips to create his own stand for the iPad so that it can be used in landscape mode. These two “mods” combined already look more convenient than the standard iPad keyboard dock, which forces you to dock the tablet in portrait mode.

Stobblehouse says the Neo is an especially good choice for travelers, since it’s full-sized, very rugged and lightweight. It looks promising.
