We’re thrilled to announce that July is kid’s month on Make: Online. We’re constantly getting requests to do more kid-related content and projects, so stay tuned over the coming month for much more of this on the site. We’ll have round-ups of our best kid-related coverage so far, in the magazine and here on the site, new kid-friendly projects, and we’re even going to invite some kids in to take our places in some of the columns, reviews, and blog postings. Who better to talk about kids and making than young makers?

It’s summertime, and that means packing up the car, the kids, and the family goat, and hitting the open road for some good ol’ Griswold family-style vacation time. Or not. You might be staying home this year. You’ll certainly likely be home for part of the summer, and that means plenty of free time with the kids (maybe more than you bargained for), a great opportunity to do something fun, something meaningful, something DIY! We call such summertime activity a MAKEcation (a productive, project-oriented answer to the so-called “staycation.”)

Taking a MAKEcation this year? We’d love to hear about it. Send use your MAKEcation plans, or better yet, documentation of your MAKEcation, and we’ll consider posting them to the site. And if we do, we’ll send you some MAKE swag.

We have MAKEcation plans. Over the course of the next quarter, we’ve got contests, project videos, and guest authors in the works. Here’s to a fun, creative, and educational summer!

Core77 talks to Apple Senior Design veep Jonathan Ive

iPhoneMaterial_2.jpg

Our friends over at Core77 got a chance to sit down with Apple’s Senior Vice President of Design, Jonathan Ive, to talk about the materials that went into, and informed the design of, the iPhone 4. Yeah, I know, the Apple haters will hate, but there’s some interesting… ah… material here, like the quote below. And when you’re in a position to develop your own materials for a product, and you’re able to achieve this quality of precision manufacturing in a reasonably affordable consumer project, that’s something worth paying attention to. At least, it gets my attention. YMMV.

That last part reminds me that there must have been a sizeable team behind the iPhone 4, and Ive confirms it, mentioning the importance of collaboration between engineering, manufacturing and design. It is an intense interplay between these fields that can yield mastery of the material, which is where everything starts with this object. “The best design explicitly acknowledges that you cannot disconnect the form from the material–the material informs the form,” says Ive. “It is the polar opposite of working virtually in CAD to create an arbitrary form that you then render as a particular material, annotating a part and saying ‘that’s wood’ and so on. Because when an object’s materials, the materials’ processes and the form are all perfectly aligned, that object has a very real resonance on lots of levels. People recognize that object as authentic and real in a very particular way.”

[Thanks, Windell!]

The curious case of the 7% resistors

Ever have an application where you needed resistors with accurate values, but couldn’t find any in your pile of cheap ones that had exactly the value was marked on them? Howard Johnson of the Electronics Design, Strategy, News blog has a surprising explanation for the phenomenon in his article, the 7% solution:

The drawing complete, Martin said, “A 10% carbon-composition resistor is made in a somewhat slipshod manner. The manufacturer tries to get it right, but some of the variables are just too difficult to control. They make up a batch, test them all, and then throw away the bad ones. What’s left is a distribution of values truncated on either side at the ±10% limits. The other main feature of the distribution is the big gap-toothed section in the middle. That’s where they pulled out all the good parts and sold them at a higher price with a ±5% tolerance. How else do you think they make 5% resistors?”

I’ve never taken the time to measure a batch of resistors to verify that this is true, however it certainly sounds plausible. Anyone here have some first hand experience with this? It seems like it would be a great exercise to go through in a practical electronics class. [via mightyohm]

Applied Kinetic Arts: Benjamin Cowden interview

benjamin cowden manifold ballast.jpg

Based in the San Francisco Bay Area, Applied Kinetic Arts (A.K.A.) is an artist collective made up of kinetic artists who each bring their own unique aesthetic and skill set to the crew. From their site, “Works incorporating motion, light, sound, and interactivity are represented by the group’s ever expanding member base.” A couple of weeks ago, I interviewed co-founder Nemo Gould as well as Jeremy Mayer . This week we catch up with Benjamin Cowden, who has contributed to the pages of MAKE magazine with his Geared Candleholder project in Volume 21. Through the project, Benjamin teaches us how to make our own gears out of metal plate, a skill he has beautifully mastered, as witnessed through his thought-provoking art.

1. Tell us about yourself. How did you get started making things and who are your inspirations?
In high school I was carving wooden figurines and sewing moccasins out of deer hide. I was committed to utility as well as a high standard of craftsmanship. In college I went abroad and studied traditional crafts in Cameroon, including basketry and knife-making, then I learned jewelry-making in San Jose, Costa Rica. I was always so impressed with people who take raw materials and, with minimal tooling, create simple, elegant items.

Geared Candleholder on Make: Projects2. How did you first become involved/interested in making kinetic art? Tell us about the first kinetic piece you made.
I lived in Tennessee, where I practiced blacksmithing and lock-making before going to graduate school in southern Illinois in 2004. In grad school, I knew I wanted to work with mechanisms, but I didn’t want to hide them inside padlocks and boxes. One night I had an epiphany and began constructing my first machine: a marionette controller. Seven months and much sweat later, this is what I ended up with. I built it piece by piece, each one designed around the previous parts, so that only the general idea of the movement was maintained. The result is awkward, but elegant at the same time.

3. What goes into building one of your pieces? What’s your process?
I generally begin with a movement I am interested in using, although sometimes I begin with a part or a theme. My recent piece Radio, for example, began when I came up with a method for building a three-dimensional piston. I do a lot of sketches to get the idea worked out, and generally move to CAD software just to get dimensions and sometimes to draw parts for laser- or waterjet-cutting. Lately I have been doing a longer design phase and shorter construction period; often about two months or more of design and about a month or two of construction.

4. What’s the biggest challenge in making art that is kinetic?
Moving sculptures, especially one-of-a-kind pieces, require maintenance and often have delicate or “finicky” parts. This makes kinetic sculpture a challenge to move, set up, and market. Coupled with an art world that is simply not set up to handle moving work (exhibition prospectuses often allow only still images, for example), kinetic artists are largely on their own to find an audience.

5. What’s your favorite tool/material?
A six-inch rigid ruler. I love measuring things.

6. How has being a part of a collective like Applied Kinetic Arts helped you and/or informed your work?
It’s a great help to have a group of mechanical geniuses around me for technical problems and learning about new mechanisms, etc. Also, having solo exhibitions is a great deal of labor and requires a large body of work; showing with AKA makes this process much easier.

benjamin-cowden-some-people-i-dont-know.jpg

7. Is your art strictly a hobby or is it a business? Does it relate to your day job?
My art practice is a business, although I have a day job as a project manager for a small custom metalwork company. I oscillate between making work that is more marketable and work that I find interesting regardless of marketability. Wayward Calliope, for example, falls into the latter category.

8. What new idea (in or outside of your field) has excited you most recently?
It seems like every week a new solar cell or wind generator comes out. I am fascinated with the idea of creating electricity for semi-random movement in sculpture. I have not found the right project yet, but it will come.

9. What is your motto?
My studio is a “do-ocracy,” not a “stand-around-and-talk-ocracy.” (Thanks, Mitch, for the word “do-ocracy”!)

10. What advice do you have for people who want to get started in the kinetic arts?
If you are interested in mechanisms, get 507 Mechanical Movements. It’s the best little book of ideas for transforming and using motion I have found.

New in the Maker Shed: Hackable Pixel Qi displays

Well, I finally get to let the cat out of the bag. We’ve got Pixel Qi screens available in the Maker Shed as of today. If you’re unfamiliar with Pixel Qi (pronounced “chee”) and their amazing 3Qi transflective display technology, here’s a bit about them from the announcement:

These screens look like standard LCD screens in ordinary room light, but take them outside in the sunlight, and see the difference! The Pixel Qi screens are bright and easy to see, even in direct sunlight. Like standard LCD displays, Pixel Qi displays show quality full-color images, full-motion video, and high screen brightness. Each pixel in the Pixel Qi screen is mainly reflective, but still has about the same efficiency as a standard LCD when backlit, enabling the user to experience a crisp image with excellent contrast and *brightness* in any light. The Pixel Qi screens consume 80% less power in the reflective mode making them a great choice for “green” applications.

Indeed, this is exciting news for anyone interested in modding their netbook or building a DIY tablet computer. Regarding the announcement, Mary Lou Jepsen, Pixel Qi’s Founder and CEO said “We hope that by working with MAKE and the DIY community, we collectively will spur innovation in ways we can’t ourselves imagine yet.”

About carrying the Pixel Qi screen in the Maker Shed, Dan Woods (GM of MAKE Ecommerce) said “We’re seeing a lot of interest in making and modding tablets, netbooks, and e-readers within the maker community, and we’re always looking for new ways to help inspire and support DIY enthusiasts to take on new challenges. Getting a brand new technology like Pixel Qi’s screen into the hands of developers and makers who will do something unusual, compelling, and unexpected which is really exciting to us. MAKE is not only uniquely positioned to inspire widespread experimentation within the global maker community, from educators to artists, software developers to hardware hackers, but also to organize conversations around resulting projects.”

I shot a quick installation video of a Pixel Qi display going into one of my netbooks. It’s an Acer Aspire One, which is physically compatible with the screen, but isn’t an officially recommended netbook.

Changing the screen is easy, the process takes about 5-10 minutes using a small screwdriver. 2-4 screws have to be removed to allow unsnapping of the front plastic bezel. Once that step is done, removal of another few screws allows the screen to be unlatched and its cable disconnected. Next, the Pixel Qi screen is plugged in, screwed in, and the bezel snapped back in place. That’s it.

Head on over to the Maker Shed for more information or to order yours today.

How-To: Trap lightning in a block

Science bad boy Theo Gray shows you how to create lightning bolts in a piece of acrylic. OK, so you need the juice of a five-million-volt particle accelerator to get the effect seen here (via the Kent State Neo Beam’s Dynamitron):

With the Dynamitron – rented for the day – adjusted to around three million volts, it blasts electrons about halfway through half-inch-thick pieces of acrylic sheet. The plastic is a very good insulator, so it traps the electrons inside. Coming out of the machine, the blocks don’t look any different, but they hold a hornet’s nest of electrons desperate to get out.

Left alone, the electrons will stay trapped for hours, but a knock with a sharp point opens a path for them to make a quick escape. Electrons gather from all parts of the block, joining up to form larger and larger streams of electric current on their way toward the exit point. As the charge leaves, it heats up and damages the plastic along the branching trails it follows, leaving a permanent trace of its path. If you could see inside a thundercloud in the nanoseconds before a bolt of lightning emerged, you would see the same kind of pattern. The bolt doesn’t just pop up fully formed; it has to gather charge from all over the cloud.

But he also explains how to create a more low-impact version in “7 Mad Science Experiments You Can Do At Home But Probably Shouldn’t,” an excerpt from his highly recommended book, Theo Gray’s Mad Science.

Stéphane Halleux is one of my favorite artists. We’ve covered his whimsical, characterful, other-worldly sculptures here before. I’ve been excited to be following his recent adventures in turning his amazing characters into a movie.

Here’s the latest video test he sent me. Even with this short piece, you can already see how lyrical, funny, charming, and just plain cool the final product is likely to be. Stéphane and company are looking for funding. Sponsorship details can be found on the film’s website.

A Concerto for Three MakerBots

CrashSpace hosted a night of hand made music on June 25th 2010. Among the performances was a Concerto for Three MakerBots composed by Frank Capodieci. MakerBots are 3D printers that create objects out of plastic, but in this case the extruder portion was removed and the stepper motors were driven at different speeds to create music.
