Build Your Own Jellyfish Habitat

Jellyfish Tank from MAKE Volume 27

Though MAKE Volume 27, which hits newsstands on July 26, is the Robots issue, like all issues of MAKE, it features a wide variety of projects. One of the major projects in Volume 27 is Alex Andon’s Jellyfish Tank. Jellyfish are hypnotic, with their translucent bodies, sweeping tentacles, and fluid motion, but they require custom tanks to prevent them from getting sucked into filtration intakes. On the pages of Volume 27, Andon, who studied biology and environmental science and is founder of Jellyfish Art, teaches you how to either convert an existing aquarium into a jellyfish habitat or how to build your own custom tank from scratch. Your choice.

Here’s the “how it works” visual breakdown:
MAKE Volume 27 Jellyfish Tank How It Works

The Jellyfish Tank is one of a few projects from the new issue that we’ve shared with you on Make: Projects, our DIY wiki. Head on over and check out the full project build. If you’re a subscriber (thanks, we love you!), you likely have your issue in hand and can turn to the project on page 82. If not, be sure to pick up Volume 27 when it hits newsstands next week.

A Handbuilt Home in Boston: “Sage’s Gypsy Wagon”

In this side episode of Tiny Yellow House, I filmed a tour of “Sage’s Gypsy Wagon” (located in Boston, MA), a mobile dwelling that was handbuilt on a very modest budget by this city-side custom-guitar maker.

NXT Wall-E

Lego NXT Wall-E transformable fully self controlled, it uses Lego Mindstorms programming environment. The video shows the transformation which is quite similar to the original Wall-E.

See the maker’s Picasa gallery showing buuild photos. Note that, in typical Mindstorms fashion, the actual transformation takes 4 minutes. [Via Inhabitots]


QR Stenciler

Golan Levin at writes:

Yep, it’s a QR code stencil generator! We present QR_STENCILER, a free, fully-automated utility which converts QR codes into vector-based stencil patterns suitable for laser-cutting. Additionally, we present QR_HOBO_CODES, a series of one hundred QR stencil designs which, covertly marked in urban spaces, may be used to warn people about danger or clue them into good situations. The QR_STENCILER and the QR_HOBO_CODES join the Adjustable Pie Chart Stencil in our suite of homebrew “infoviz graffiti” tools for locative and situated information display.

How-To: Magnetically Demountable Ocular Simulators

I went through a googly-eyes phase when I was in college, wandering ’round applying them to the most inappropriate and disturbing objects I could find, and taking pictures. The mentionable results of this project include googly-eyed tombstones, firearms, surgical instruments, and urinal cakes. None of these photos will ever see the light of day. You’re welcome.

Anyway, I wish it had occurred to me, at the time, to mount magnets on ‘em as the clever wonks at EMSL now have done. Would’ve saved myself a bit of money, and rather a lot of time removing adhesive from some very unpleasant places.


Making EL Wire Change Color

It’s not a dramatic color shift, but it turns out you can control the hue of EL wire over a narrow range by varying the frequency of the resonating driver circuit. dcroy (upper video) did it back in February using a 555, and Paul Stoffregen (lower video) unknowingly repeated the project recently, having noticed that a single fixed-frequency driver produced slightly different colors in two different lengths of wire. My guess is that EL wire manufacturers strive to minimize this variance, which for many users would count as a defect. But I wonder if you could change the phosphors or otherwise tweak the wire’s design to maximize the frequency-dependent color-shift?


New in the Maker Shed: Telerobotic Gripper Kit

Telerobotic Gripper Kit
Get a grip with the Telerobotic Gripper Kit from the Maker Shed! This kit includes everything you need to make the Teleclaw featured in MAKE: Volume 27, even the batteries! Assemble the kit and attach it to your robot, rover, or anywhere else you could use an extra hand. The pre-programmed Picaxe microcontroller interprets commands from the IR remote to make the gripper open and close. Have a look at the Make: Projects build for more information and directions.
