Adafruit debuts Circuit Playground: a show teaching kids about electronics (video)
Programs have a certain magic power over littluns, sending them into a trance-like state and then having them beg for merchandise afterwards. The perpetual tinkerers over at Adafruit don't expect you to catch 'em all, though, and have debuted their own show called Circuit Playground -- an educational YouTube series teaching kids about electronics. In the first episode, we learn all about Amperes and are introduced to our hosts: a free-willed human and ADABOT, a charming puppet presenter (just don't tell them that). Following the letters of the alphabet, expect 25 more installments and, if the intro sequence is any indication, a bunch of component-based characters to keep the sprogs interested. If you need 3 minutes and 50 seconds of peace and quiet, or just want to brush up on the basics yourself, head past the break for the first episode. Next time on Circuit Playground: "B is for Battery."
Adafruit's Limor Fried takes on the Engadget Questionnaire
Every week, a new and interesting human being tackles our decidedly geeky take on the Proustian Q&A. This is the Engadget Questionnaire. In the inaugural appearance of our questionnaire on Engadget, Adafruit founder Limor Fried opens up about her love for her Metcal MX-500 soldering station and the joys of open-source build projects. Follow us after the break for more from Limor.
Arduino Micro shrinks your favorite DIY platform down to ridiculous proportions
With the Arduino Leonardo, everyone's favorite hackable microcontroller turned a new page. Now it's time to bring that simplified design and slightly expanded feature set to the rest of the family, including the itty-bitty Arduino Micro. The tiny, embed-friendly board was designed with help from Adafruit Industries, one of the biggest players in the DIY market. At the heart of the Micro is the same 16MHz ATmega32u4 chip that powers the Leonardo, which means all the necessary USB controls are baked into the processor. Obviously, the layout here is different, so you wont be mounting the Micro to any shields, but with 20 digital I/O pins, 12 analog input channels and seven PWM channels, there's plenty of room for wiring up your own expansions. Amazingly it crams all that capability in a package just 48mm long and 18mm wide. The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $27) and without headers for €18 (about $23). For more, check out the PR after the break.
Adafruit builds Raspberry Pi-powered light painting rig, takes trippy photos
Taking long exposure photographs at night and painting within them using an iPad may be old hat, but building your own light painting rig? That could earn you some serious geek cred, and according to Adafruit, it isn't even all that hard. In a new walkthrough, the team fashioned such a contraption using a Raspberry Pi, a python script with under 60 lines of code, some open source software and a handful of electronic components. Not satisfied with the typical light wand, they decided to spice things up with a circular fixture built from PVC pipes and a hula hoop to hold the ribbon of LEDs. After being attached to a bike and paraded around at night, it created the 3D effect in the masterpiece above. If you're itching to make your own works of art, check out Adafruit's tutorial at the source link below.
OLED Lego train station emerges from Adafruit and Arduino gear, minifigs to get home on time
Who knew Lego characters had to be somewhere in a hurry? Adafruit did, as it just whipped up a minifig-sized train schedule. The invention mates one of Adafruit's own 1-inch OLED boards with an Arduino Uno controlling the schedule behind the scenes. It looks to be a straightforward project for the DIY types, although the display is currently all show: the schedule doesn't (yet) pair up with the train tracks to automatically let your minifigs know if their trip to the pirate spaceship castle has been delayed by ghosts. You can check the source link for the full instructions. Duplo builders, alas, are kept out of the loop.
Keep your bands straight with Adafruit's Ohm Sweet Ohm cross-stitch kit (video)
Doesn't it just seem like yesterday when Grandma used to embroider your resistor charts for you? But now that you're grown up, Adafruit wants you to cross-stitch the Ohm Sweet Ohm color band guide yourself with their handy kit (dog not included). Spec-wise, it's loaded up with 16 skeins of floss, two size 24 tapestry needles, 15 x 18-inch 14-count aida cloth and a 6-inch "super grip lip" embroidery hoop, all for $29.95. You'll also get a full color printed pattern with instructions on making the project, then how to mount it on the wall or sew it onto Spot's favorite pillow. So if you can never remember whether yellow in the C-band is four significant figures or five, and want an Ohm-y reminder -- then check the video after the break for more info.
Adafruit modder builds Captain Jack's Vortex Manipulator / Leela's wrist-lo-jacko-mator for real
This impressive wrist / forearm cuff is the brainchild of Adafruit forum member and modder Stephanie, who has built a sensor platform into the fashion accessory. The device can monitor the exposure value, track your movements over GPS, measure your galvanic skin response, tell you the temperature, humidity and even doubles as a watch and flash-light. It was built around Sparkfun's Pro Micro development board and a boatload of sensors purchased from Adafruit. We might just build one ourselves with a radiation detector, so that we can live out our Pip-Boy fantasies down at the mall. %Gallery-156412%
Adafruit's Circuit Playground app deciphers resistor codes, helps you remember Ohm's Law
If the names Phillip Torrone, Limor Fried and Collin Cunningham don't ring a bell then you probably need to hand over your geek badge. If, on the other hand, those names immediately make you sit up and pay attention, you maybe excited to hear the trio have just released the first Adafruit-branded app for iOS. Circuit Playground is a reference app for makers, hackers and tinkerers that helps you decipher resistor and capacitor values; calculate resistance, current or voltage; convert decimal, hexadecimal and binary values; and store PDF data sheets for ICs. The app is $2.99, but it comes with a $3 credit at the Adafruit shop, so it's kinda-sorta free. It's available for iPad and iPhone only, but an Android version is in the works. If you're an impatient Google fan, they suggest you check out ElectroDroid which performs many of the same functions and we can confirm is awesome. Check out the video after the break and hit up the source link to get Circuit Playground now.
Kinect hack explained: follow-along-at-home guide lets you reverse engineer USB, impress your friends
So, there's already an open source driver for the Kinect -- who needs to learn how to reverse engineer USB all over again? Well, ladyada of Adafruit Industries, the folks responsible for the Kinect hack bounty and the USB logs used by the bounty winner to get a jump on his hack, has published a detailed guide on exactly how she sniffed the Kinect's USB chatter. The guide isn't for the faint of heart, but it's not completely unintelligible to someone with a bit of time and determination. If anything it serves as an excellent bit of how-the-Kinect-was-won history. We're not expecting Microsoft to reconsider its "Microsoft does not condone the modification of its products" stance on this issue, or its petty threat of law enforcement "to keep Kinect tamper-resistant," but we do hope they've learned one thing by now: they're fighting a losing battle.
Open Source Hardware community finally gets its Constitution
They, the people of the open source hardware movement, in order to form a more peaceful community for sharing, establish bigger and cuddlier Chumbies, ensure continued Arduino creativity, promote the general welfare, and secure the blessings of hackery to ourselves and our posterity, have established the Open Source Hardware Draft. It's a sort of 11 commandments for those who would share or use an open source hardware design, indicating what documentation is required, how derived works must be allowed and, perhaps most importantly, that each use must include attribution to those founding engineers who came before. Its current version, 0.3, was ratified yesterday by a group of dignitaries including folks behind the Arduino, Adafruit, and Chumby, along with plenty of other underground industry big-wigs. Now that this bit of official business is out of the way, hopefully they can all get back to crafting homemade coilguns.
Adafruit's Monochron retro clock now on sale, changes time with every match point
You might have the vaguest of memories seeing this piece before -- it made a cameo in an Engadget Show segment -- but here we are with a much clearer picture of Adafruit Industries' Monochron clock, now also on sale! As is its modus operandi, the timepiece is open source... but should you plan on sticking to default, you'll be gifted with a great retro-style Table Tennis for two. The best part? The time changes whenever the clock "loses" -- something tells us that gives one side at least a 59-to-1 advantage. See for yourself after the break.
Adafruit is in the Square payment pilot, awesomeness will likely ensue
Our good friends at Adafruit Industries are now taking mobile payments with the best of 'em thanks to a prerelease Square dongle they've managed to score, ostensibly as a part of the public trial announced earlier this month. They've posted a quick video showing the process of taking someone's cash via plastic, and it looks every bit as painless as Square makes it out to be -- just swipe, sign with your fingertip, and your Square-equipped payee is a few dollars richer. The particular dongle Adafruit's been provided looks rough to say the least -- these aren't the units you'll be getting off the shelf -- but that's part of the fun of being involved with a beta, isn't it? Head over to Adafruit to peep the video, and needless to say, we're curious to see how they plan to make use of this little bugger.
The Engadget Show: Kindle etching and DIY adventures with Adafruit Industries
If you'll recall, some months ago we held a little competition for readers to submit artwork destined for laser-etching on the backsides of Amazon's Kindle. After everyone voted on the top five out of the mountain of selections, we took the gaggle of readers down to our friends at Adafruit Industries (headed up by the lovely and delightful Limor Fried and Phil Torrone) for some time under the laser. While we were there getting our etch on with their massive laser, we convinced Limor and Phil to show off some of the other crazy kit they've got in the labs -- and we've captured it all on film... er, video. Take a look at our excursion into the world of dynamic DIY'ing -- we think you'll like what you see. Check it out after the break!

Design your own Kindle (and win it) with Engadget, Amazon, and Adafruit Industries!
Reading isn't just about the text that you're reading, it's an intimately personal experience in every sense of the word -- the way the book feels, the crease of the pages, the wear on the cover, it's all totally unique to your copy at the time that you're reading it. Put simply, it's an experience no one else will ever have. Between three models, dozens of accessories, and countless e-books, no two Kindles are alike, either -- but Engadget has partnered with Amazon and the DIY experts over at Adafruit Industries to hook up five extraordinarily lucky readers with truly unique reading devices. These guys are the laser etching experts -- see one of the Kindles they've done here!Here's the deal: we're asking you to think of a design that would look great on the Kindle's brushed metal back -- something that means a lot to you, something that'll make passers-by drool with envy when you casually hold up your new toy while reading The Economist from the comfort of your train, plane, or bus seat. Draft up that design (seriously, make sure it's awesome, because you'll be facing some stiff competition) and send it to us. We'll post some of our favorites as finalists and hand the reigns over to you -- our dear readers -- to select five winners who will each have their designs laser-etched into reality on the backs of their very own Kindles!The rules: Send your design to us by emailing it to contests [at] engadget [dawt] com with the subject "I want my custom Kindle!" (no quotes). Submissions must be in EPS or AI format, must be in black and white only, and must be composed strictly of vector graphics with all fonts converted to curves. We can scale your design as necessary, but keep in mind that you'll be dealing with an etchable area roughly five inches by seven inches. You can find a (very large) image of the back of the Kindle 2 here for your reference. We can't print anything you don't have the rights for, so to be safe, original work is the best! You may only enter this specific giveaway once. If you enter this giveaway more than once you'll be automatically disqualified, etc. (Yes, we have robots that thoroughly check to ensure fairness.) Contest is open to anyone in the 50 States, 18 or older! Sorry, we don't make this rule (we hate excluding anyone), so be mad at our lawyers and contest laws if you have to be mad. Five (5) winners will each receive one (1) Amazon Kindle 6" Wireless Reading Device customized by Adafruit Industries. Approximate retail value is $299.00. If you are chosen, you will be notified by email. Winners must respond within three days of the end of the contest. If you do not respond within that period, another winner will be chosen. Design entries can be submitted until Friday, July 24th, at 11:59PM ET. Good luck! Full rules can be found here.
Adafruit's Citizen Engineer comic book / SIM card reader kit
The gang at Adafruit Industries are on a mission -- and they won't rest until every man, woman, and child on this planet has access to the DIY and open source electronics they crave. The most recent project of theirs, Citizen Engineer: SIM Card Hacking, is a comic book that both serves as a primer on GSM and SIM cards and tells you how to build a SIM card reader. And if that weren't awesome enough, if you purchase the title for $35 they'll throw in the reader kit -- either enabling your thirst for knowledge or jump-starting you on your path towards a new life as a hacker / fixer for the Russian Mafia. Video after the break.
Video: Kindle 2 sees the wrong end of a laser, recommends you don't panic
If there were anything a frequent traveler needs more than a towel (and money, and identification, and maybe a cellphone...) it's a Kindle 2. To celebrate its ability to provide free access to the world's great information repository from absolutely anywhere (within in the United States that has cellular access), Adafruit Industries has turned the K2 into something of an ode to Douglas Adams's great epic: The Hitchhiker's Guide to the Galaxy. After a little burning action courtesy of its Epliog 35 watt laser (which we've seen in action before), the e-book reader now sports the most valuable advice ever given to a man (or alien). Sadly it still won't give you directions to the Restaurant at the End of the Universe, but it will at least let you download and start reading it in under a minute. Ford Prefect would be proud.
