Picture of the XO-2 OLPC

First-Leaked-Picture-Of-The-Next-Generation-Xo-2-Olpc-Laptop-2
Leaked picture of the upcoming XO-2 OLPC via netbooknews.de. The next OLPC is being reported to be an open source hardware project too...

It appears that the very first photo of the next-generation OLPC XO 2.0 low-cost laptop has finally emerged on the Internet, showing us some of the things we should be expecting. In addition to that, it looks like Nicholas Negroponte, the founder of the One Laptop Per Child project, has confirmed that the next-generation XO laptop is going for a different design and marketing strategy. To be more specific, the upcoming laptop, which could be released sooner rather than later, will be meant to provide users with a book that can be a laptop as compared with the first XO laptop, which was meant as a laptop that could be a book.

Make: television polecam photo from AOTS

AOTSfiringSquad.jpg

During my appearance on Attack of the Show! this week, Kevin Pereira lined up some crew members to shoot with the Burrito Blaster. Brave souls. This is a photo of them, along with lovely co-host Olivia Munn, that Kevin took using the remote-controlled pole camera rig. One clever thing segment producer Sean Jordan thought of was to tap into the camera's video out so we could monitor what the camera saw. I wish we'd thought of that! This is just a humble point-and-shoot camera, too, so it may be a pretty solid addition to the project. If you want to see what you're shooting, just run a long RCA cable down the pole to a small monitor or video camera with a composite input.

SSerial2Mobile - SMS library for Arduino

sserial2mobile_20090130.jpg

This looks like a handy library for mobile-enabling your next Arduino project:

This library implements the Software serial Arduino library to establish a serial connection to a Mobile phone. The methods methods hides the AT+ commands from the user allowing messages to be sent by passing the method on a phone number or email and the message.

The specific AT commands were made to work with the Motorolla C168i, but you can tweak a header file to adjust things for the specific device you are using. It makes sending an email or SMS almost as easy as a single function call:

Example code:


#define rxPin 2
#define txPin 3

// set up a new serial port
SSerial2Mobile phone = SSerial2Mobile(rxPin, txPin);

//send a text message
phone.sendTxt("+15555550125","Lib SMS Test1");

//send an email
phone.sendEmail("sserial2mobile@example.com", "Lib email test1");

The reason the author chose to use the C168i is that you can get the phone on the cheap, without contract, and prepay for SMS service. It's also simple to make a serial cable which connects to a 3/32" stereo plug on the phone. In all, it looks like a pretty simple and cheap task to get this all working.

Note that it's the last day to use code 2009OX during checkout in the Maker Shed for a 10% discount. If you need an Arduino for this, go get one now!

Introducing the Maker'skine

makerskine013009.jpg

I did a double-take when Collin sent me the link to this Flickr image of a Mini Maker's Notebook. What the...? It's one of our pal's Kent Barnes' "5 Minute Hacks." He made a Maker's Notebook paper book cover for a pocket-size Moleskine. Maybe if we ask real nice, he'll let us post the PDF so you can Maker-fy your own mini notebooks.

Linoleum Asphalt Mosaics - CRAFT Video Podcast

Linoleum asphalt mosaics, also called Toynbee Tiles, are artworks permanently embedded in pavement. In this video I'll show you how to construct your own from inexpensive materials. You can get real linoleum (don't use vinyl flooring) for this project by ordering free samples online. By cutting out a mosaic design in the linoleum and sandwiching it between layers of paper, wood glue, and asphalt crack filler, you can affix the mosaic very permanently to an asphalt surface, such as your driveway. You may choose to use a heat gun to make the linoleum easier to cut, or even a laser cutter. The earliest examples of these tiles were found in the 70s and 80s on streets in Philadelphia, all bearing the same (or very similar) message: "Toynbee idea / in Kubrick's 2001 / resurrect dead / on planet Jupiter." They are speculated to have been created by the same person until they began to gain a following. There's an active message board on the topic which shares sightings and other information. If you make one, please share your pictures in the CRAFT Flickr pool!

Subscribe to the CRAFT Podcast in iTunes, or download the mov, mp4, or iPhone/Android video.

Thanks to my pal Matt Mechtley for his help on this one. In this video I used this cc-licensed photo by Flickr user mojunk. The music is "Regurgitation Pumping Station" from the World of Goo soundtrack by Kyle Gabler; used with permission.

Building papercrete domes

dome1.jpg

I blog about Mikey and Wendy's projects very frequently because they're doing so many cool things. One of the most impressive is their papercrete dome, which is now documented in this Instructable:

When my girlfriend (Wendy Tremayne) and I arrived in southern New Mexico one of the first things we did was look around for a local building material. Clay would need to be excavated and hauled in, straw bale was already expensive and not local, manufactured building materials like rastra were a little too off the shelf for us. We ended up settling on what we had locally available and that was/is paper. It is common for small remote towns to not have much in the way of recycling. Our town was collecting paper, but more often than not would just dump it in the landfill after collection. They were happy to help us load our truck up with their newspaper which was mostly a nuisance to them. We later found a source of rebar being made from old cars within a 100 miles of our place.

Since we would have a lot of batteries and solar PV equipment that needed a good home we decided to do our first structure as a battery room for our solar equipment. Domes are inherently strong and energy efficient structures. This is how we started building a battery dome from paper.

Great, inspiring work, y'all!

Physics of music and musical instruments

music box.jpg

Tufts University has a really good book available online about the physics of music and musical instruments. It's a nice balance between theory, examples, and hands-on projects.

The Physics of Music and Musical Instruments covers the physics of waves, sound, music, and musical instruments at a level designed for high school physics. However, it is also a resource for those teaching or learning waves and sound from the middle school through college, at the mathematical or conceptual level.

Lamps made from recycled cardboard will illuminate your world

santiago_recycledlamp.jpg

Santiago Morahan's cardboard furniture is a cheap and easy solution for the multitudes of cardboard boxes that most people have hanging around their homes. The artist has stacked them up, cut a hole in the middle, and fire-proofed the cardboard so that the heat of the lamp doesn't burn down the house. The result looks like a lost set piece from Bladerunner and will definitely make your neighbors envious.

Eco-Gym

MOE_ecogym
The modern gymnasium is very much a 19th- century creation, no matter how much the fitness freak is kitted out with bad hair, retro headbands, and spandex, or contemporary embedded LCD interfaces and computer-generated body plans. Gyms harken back to a world of classical mechanical physics, plugged into equations of work and energy.

To the strains of Olivia Newton-John's aerobics anthem, the puritan work ethic is transformed into a sweatshop for the body beautiful. The slick machines, treadmills, and cross trainers merely serve to disguise antique apparatuses more at home in a world of steam engines, and to stifle enquiry into thermodynamics and economy.

Then there's artisan Manuel de Arriba Ares. Under the sign of his "eco-gym," Gimnasio Ecológico Lumen, Arriba has turned the demon of entropy on its head. Making use of the very waste and byproducts of the modern entropic economy, Arriba has created a truly practical monument in the form of a supremely low-tech gymnasium. Its fitness machines, created with a good deal of physical effort over three years from raw and junked materials such as wood, rope, and rubber, directly mirror both the design and functionality of those found within its wasteful counterpart.

Located in the small town of Valdespino de Somoza in the north of Spain, Arriba offers free access for all to this functional work of Art Brut, a wonderful Heath Robinsonesque assemblage constructed from remnants of strollers, boats, bicycles, and automobiles salvaged from neighboring dumps.

Helpful signs, painted on the tarnished white remnants of refrigerators, instruct the would-be eco-gymnast on exercises and operation of the intricate machinery, reflecting Arriba's knowledge and experience over many years as a physical education teacher.

Lumen is a "gymnasium that was born of the nature, (and which) will return to her," Arriba philosophizes. The cycle of waste, embodied by so many aspects of the smogged-out city gym, is closed.

Best of Instructables excerpt: Mousebot revisited

Best of Instructables cover

Here's another Make: Books PDF excerpt. This one comes from the Best of Instructables, which is a compilation of some of the most amazing projects from Instructables, the world's biggest show and tell. This excerpt is kind of special to us. In it, former Make intern Jacob McKenzie riffs on a project by Gareth Branwyn, Lead Editor for this book:

Gareth Branwyn's "Mousey the Junkbot," from MAKE Volume 02, is a fun introduction to robotics. So fun, that I've created this expanded documentation of a Mousey build from start to finish, with a few extra tips and tricks you won't find in the magazine project. This how-to is best understood after reading the original article, found on page 100 of Volume 02 (or in The Best of MAKE collection), however it is probably not required.


Mousey is a simple bot that uses two "eyes" to sense light and then turns towards the light it detects. A single large "whisker" is mounted on the front to detect collisions. A collision with a wall will cause the bot to reverse and turn, then take off in another direction. This project is pretty cheap if you have a mouse to use, the other parts can be obtained for less than ten dollars.

Mousey requires several parts that we can conveniently borrow from a donor mouse, its eyes and its whisker. Open up the mouse and locate the components that we'll be harvesting, the momentary switch and the infrared emitters. The emitters are the components in the clear package (Figure C)...

Follow this link for the full excerpt.
