Can't wait to cozy up to the new Apple iPad? Why not try your hand at constructing this handsome papercraft surrogate? Here's links to the front and back. It may not have access to your iTunes or eBooks like the real thing, but it does share its good looks and lack of multitasking, GPS, and camera. [via MacRumors]

Because you can, obviously. This DIY video will run through the basics of chaining together polycrystalline cells and leaves the details like enclosure and such to the user.

William Stranger specializes in building furniture out of repurposed wood. I especially liked the massive coffee table whose top is a four-inch-thick slab of bowling lane. It's part of a exhibit(?) called Second Growth:
A second growth forest is one that has re-grown after it has been heavily logged or clear-cut. The installation of reclaimed materials, organic furniture and hand carved objects suggests the life cycle of a tree. It encourages a closer look at the relationship between consumption and conservation and promotes the idea of a culture in balance with the natural world. A tree is borrowed from its cycle without breaking it. The wood is worked with attention, treated with non-toxic finishes, and after its long second life it will return to nourish the earth. Scrap wood is saved and becomes the raw material for innovative design.

A commenter on my recent dazzle camouflage post alerted us to the fascinating story of the HNLMS Abraham Crijnssen which, in 1942, escaped destruction by the Japanese fleet because the crew moored her among other small islands and covered her in a thick layer of tree branches, thereby disguising her as a small island. [Thanks, rekinom!]

Check out UK maker John Honniball's sweet workshop panorama.
This is an almost-360-degree panorama of my computer and electronics lab and workshop room. The four big CRT monitors that you can see were obtained from FreeCycle, as was the iMac. Far left is a Stag PPZ EPROM programmer. At the right-hand end are the HP stack (1980B, 1630G, 3456A) and a Tek 575 curve tracer. Far right is an HP LaserJet 4+ with duplexer. On the electronics bench, you may be able to see an Arduino and some LEDs.
See the panorama full-sized on John's Flickr page.

Brooklyn-based hacker collective NYC Resistor is holding its first 48-hour hackathon this Friday starting at 6pm and ending Sunday, February 14th at the same time.
You can work by yourself or with a team, and if you don't have a team/project we'll assign you to one.The format is open, you're welcome to come and go as you please. We'll keep the Club Mate flowing and follow a loose schedule of demos and workshops to help spark your imagination.
Interested in participating? Find out more information or register on Eventbrite.

I just can't get enough flatpack.
The Belkiz Feedaway is a cardboard portable feeding chair that can be used for temporary situations or where space is at a premium. It is cardboard, easy to assemble for toddlers up to 20 months of age up to 20kg who are away from home. Ideal for temporary and commercial use, the Belkiz Feedaway is safe, strong, folds up easily and quickly and stores away in a tiny space. Ideal for mobile and modern lifestyles.
What do you think, readers? A silly concept that would never work, or is there a cool idea here? [via Inhabitat]
These are lovely.
I also like these fishing lure earrings from CRAFT volume 03...
And of course, iPhone home button earrings...
The forces that affect buildings and other structures can be modeled inexpensively and quickly by using the humble drinking straw. Usually, the projects built with drinking straws are rapid build. Storage can be an issue if you plan on having students work the design over multiple classes, or saving the structure for reference. This really becomes a problem if you are doing the same project with a full load of 5 classes. By doing the project in a single class period, you can easily reuse the straws, having students discard any cut ones and replenish them with new for the next group.
For fasteners, there are a few options. Tape can work, but is hard to remove if you are reusing straws. This can be good if you are aiming for a more durable product. Sewing pins can be used over an over again. Having students count out the pins they need and keeping them in plastic cups is works for multiple classes. As a new batch of kids collects their supplies, they just check to see that the last group left the right number of pins in the cup. This can occur at the same time they get the straws they will need. Some towers are built with paper clips as the fastener. If you do this, you may give the option of using wire cutters and pliers to modify the pins.
In introducing the ideas of the project, you will want to discuss the forces of tension, compression, torsion and shear. As students build, they should be able to recognize the forces that affect buildings and other structures and devise ways to compensate for them.
Often in straw towers, you will want to incorporate the differences between live load and dead load. Sometimes called dynamic load and static load, you can model them by having the tower hold a weight, representing the live or dynamic load. You can also have students become more aware of factor of safety and failure analysis of their structure.
The building of these towers can lead to a competitive situation. You can have students all build with the same materials, and set the grades on how high the towers stand while holding the live load. One way of doing the calculation is to set the highest and lowest possible grade, 100 and 75 for example. Then you measure the towers, identifying the tallest structure. If the tallest tower is 50 inches, then each inch is worth 1/2 point. The group with the tallest load bearing tower gets the 100. A tower that holds the live load at 40 inches would get a 95. The group that has the ball on the floor gets the 75. The other groups in between get grades based on the height of the ball, or other load.
You can also use a project like this to examine the forces affecting a building during an earthquake.
Have you built a straw tower as a student, or have you used the project as a teacher? How well does a project like this work in homeschooling? What techniques work well, and what resources are really helpful?
