Make: Projects – Custom-Shaped Frameless Eyeglasses

Here is a process that would not have occurred to me. Make: Projects user Kiers knew enough about the machines used by eyeglass lens makers to know that they use a “dummy lens” template as a pattern to cut the outer profile of a lens. He found an accommodating online optician willing to use a customer-provided pattern to make frameless glasses, which allowed him to design a lens shape to complement his own face in software and laser-cut a custom pattern.

Pecha Kucha SF – Creating Outside The Lines

[Click on the headline above to see the entire photo gallery]

Last night I enjoyed the monthly Pecha Kucha event in San Francisco (pronounced pe-CHA-k’cha, quickly). It’s like Dorkbot for designers, but with a format similar to Ignite events.  Each presenter has 20 slides that show for 20 seconds each, and advance automatically. The event took place at the Children’s Creativity Museum (formerly, Zeum), and the theme was “Creating outside the lines.”

Here Are Some Highlights:

  1. Cartoonist Nick Dragotta, who draws Howtoons in MAKE magazine, talked about DIY comics and demonstrated the classic Marshmallow Shooter project that appeared in MAKE Volume 02. Dragotta explained that he and the other Howtoons collaborators avoid being didactic. They never say “here, do this,” but instead integrate the how-to information into the storytelling. The Howtoons cartoons are anthologized in two books, and because the first book includes cartoons showing power tools, the publisher was afraid of having it shelved in the Children’s section of bookstores– so it went into the adult Science instead.
  2. Designer Alberto Villareal showed how he and some pals turned some misprinted books into skateboard decks, by cutting the pages out, folding and weaving them together, then encasing them in resin. Originally they just poured the resin over the paper, but the result was too flexible, so they made a fiberglass mold of a skateboard deck and cast the paper and resin inside. The resulting skateboard is heavier and more flexible than a plywood skateboard.
  3. Balloon artist Brian Asman presented his work and explained that, after seeing the play R. Buckminster Fuller: The History (And Mystery) Of The Universe, he was inspired to develop a tetrahedron balloon element. It was so strong that it became the basis for a full-size balloon sofa that adults can sit on.
  4. Artist Jenny Chapman described her public sculpture Manifest Destiny! (in collaboration with Mark Reigelman), for which a small steel-framed log cabin was grafted four stories high onto the side of the Hotel des Artes building in San Francisco. She also described her Bridge Equality project, which seeks to make a political cause of temporarily switching the paint colors between the Golden Gate and Oakland Bay bridges.
  5. Furniture maker Dylan Gold showed some of his amazing designs, eliciting gasps from the audience. He described M. C. Escher as an early influence, and recounted his career trajectory from commercial graphic artist to woodworker. (Photo: Garry McLeod)
  6. Sam Haynor described what it’s like to help kids develop their own inventions at the Mission Science Workshop, a makerspace for underprivileged youth. He said that the empowerment of things like drill presses and chain saws is unparallelled in the kids’ lives, and observed that the fourth grade is about the age that kids start crossing out their own drawings because they didn’t turn out right.  One example invention he helped a kid with was The Farting Poopunator, a device conceived to collect farts and poo from the user, for throwing at enemies. Using this example, Haynor explained how the process of invention and hands-on development with children is more important than the end product.

Fun! Pecha Kucha events take place in dozens of cities, and are expanding to more locations with support from Autodesk.

How-To: Make Conductive Ink

Conductive Ink from Jordan Bunker

There are so many cool projects out there that use conductive ink, but where to get the ink? Now you can DIY that part, too!

Jordan Bunker of Pumping Station: One in Chicago embarked on this chemistry project and documented the UIUC process into easy-to-follow instructions.

Conductive inks have a myriad of different interesting applications. As a quick, additive construction method for electronic circuits, they are especially intriguing. Unfortunately, for a long time they have been just out of reach of the hobby market. They are too expensive to buy in decent quantities, too complicated to make, too resistive to be practical, or require high annealing temperatures (which would ruin many of the materials you’d want to put traces on).

Now, thanks to some brilliant minds at the UIUC Materials Research Laboratory, you can make your own decent conductive ink!

As with most things worth doing, there are risks.

NOTE: Please don’t do this at home unless you understand the risks and dangers and know how to avoid them. In fact, it’s best that you have a chemist or someone experienced with how to handle chemicals properly help you.

Ammonium hydroxide is nasty stuff. Formic Acid is even worse (It’s basically liquid pain. It’s the chemical in ant bites and bee stings that makes them hurt). Please respect this stuff.

See the material list, full process, and trial and error on Jordan’s post.

Robot Tourist is a Land Surveying Blimp

Ezer Lichtenstein of ITP made an autonomous blimp called the Robot Tourist that can sense its surroundings and take photos of the landscape it flies over. This was accomplished using a Link Sprite camera, a microSD Arduino shield, and an Arduino Uno.

From Ezer’s site:

My initial intention in creating this was to make something that you could set forth in the world and pretty much forget about, and then after some period of time (hours, days, weeks) this thing would come back to you or you’d search it out and you would be able to see all it’s little adventures. Maybe if you built enough of these, you could ‘crowd’ source any sort of large scale data collection job. For instance if you wanted to catalogue the beds of large lakes or the inside of caves or cloud formations. You could also have it just catalogue wildlife in remote areas. Or take one more step toward singularity.

The blimp made its tethered maiden voyage in Brooklyn and snapped a few shots of the landscape below. The blimp is equipped with solar panels, but it will take further testing to determine whether these can be a sustainable power source.

Recycled Firehose Swing

A quick eBay search reveals that, in fact, used fire hoses are quite readily available, and not very expensive. The bentwood seat would be a little more challenging, but as woodbending projects go, that shape wouldn’t make for a very difficult one. Or you could just use an unbent seat. It’s the work of designer Michael Hensel. [via Recyclart]

Make: Talk 006 – William Gurstelle, Backyard Ballistics

Make-Talk-1

Here’s the 6th episode of MAKE‘s podcast, Make: Talk! In each episode, I’ll interview one of the makers featured in the magazine.

Our maker this week is William Gurstelle. He’s a contributing editor to MAKE and his books include Backyard Ballistics, Adventures from the Technology Underground, and Absinthe and Flamethrowers. In addition, Bill writes frequently on culture and technology for national magazines and blogs including The Atlantic, Wired, and Popular Science.

Here’s are some projects William has done for MAKE:

Two-Can Stirling Engine Bullwhip Double Pendulum
Super Tritone Shop Whistle

What is a Hacker? Ask One.

I love this pair of “interviews” that hacker legends Mitch Altman and Emmanuel Goldstein gave to the Media Show.

When someone says they are a hacker, what do they mean? Are they just big computer geeks? Are they doing illegal criminal things, breaking in and stealing passwords? Mitch Altman, inventor of the TV-B-Gone, tells us hacking is about thinking differently about the world around you. Featuring the folks at the Noisebridge hackerspace in San Francisco, who show off their projects with bikes, toys, clothes, food, electricity, and even outer space!

BTW, it looks like the Media Show could use a little support to stay running. [via Drew Fustini]

How-To: Build and Use an Afghan Box Camera

My old pal, Bay Area shutterbug Billy Baque, has a passion for the handmade, low-tech, all-in-one cameras-plus-darkrooms used by street photographers around the world.  The so-called Cuban Polaroid is a typical example—a wooden box with a light-tight sleeve for the photographer’s arm at one end and a lens on the other. Billy describes the typical use:

Using photographic printing paper the photographer would expose a sheet of paper for the negative, develop, stop, and fix it inside the camera, then put a copy stand on the camera and photograph the negative (to obtain a positive), develop, stop, and fix, then wash the final print in a coffee can of water attached to his homemade tripod.

Billy just hipped me to Lukas Birk’s Afghan Box Camera Project, an ethnographic study documenting the rapidly-vanishing traditions, technologies, and skills of street photographers in  Kabul.  The Afghan version of the Cuban Polaroid is known as the kamra-e-faoree, and Mr. Birk has gone to considerable lengths to document its traditional construction and use, preparing a detailed build guide and an on-site video minutely recording lifelong Kabuli street photographer Qalam Nabi, in action, with his. [Thanks, Billy!]

WWII Air Raid Siren Speaker Conversion

Listen to your iPhone loud and clear with this vintage WWII era air raid siren conversion. Austin’s Chase and Scout preserved the speaker’s industrial vibe while updating it for modern playback. You can connect pretty much anything with a standard 1/8″ headphone jack to the recessed amplifier and 6″ powered speaker for a unique listening experience.
