Voyage of a $10 Bill

Voyage of a $10 Bill

MAKE headquarters received a visit yesterday by three gentlemen on an interesting (and very random) mission: following a $10 bill on its journey across the U.S. for a month. Filmmakers John Hardwick and Ben Unwin, along with journalist Steve Boggan, had traveled to the States from the U.K. to make a film about the journey of one particular $10 bill for the month of October. Their journey began in Belle Fourche, South Dakota, the geographic center of the U.S. (counting Hawaii and Alaska). They chose a person to give the bill to and then followed it as it got spent.

Along their journey, in Texas, one person mailed it to someone in California, and the three had to high-tail it out to the West Coast, where the bill eventually got spent at Renga Arts in Sebastopol, which happens to be owned by Joe Szuecs and Sherry Huss (director of Maker Faire), explaining how they ended up at MAKE headquarters. They had no shortage of interesting stories to share from their trip so far, but by and large they were overwhelmed by the kindness of strangers in this country, which is always refreshing to hear. For the course of this month, they’re tweeting from tenbuckben (Unwin) and tendollarguy (Boggan). Looks like MAKE headquarters and MAKE Labs may end up in their flick.

Sound-Activated and Wearable Light Organ


About the size of two 9V batteries, and powered by only one, our latest Weekend Project, the Light Organ, is both portable and fun! The beating heart of this project is the LM324 Integrated Circuit (IC), the black chip in the middle of the board. This legendary IC actually has four operational amplifiers (or “op-amps”) embedded in it, although for the purpose of this project, we’re only using two. Converting sound into light via the condenser mic element (the round component at the bottom of the board), this project is reminiscent of light organs from the 1970s. Still confused? Check out the video below to see the Light Organ in action and I guarantee you’ll go “Aha!”

This is another super-simple Weekend Projects circuit design but I admit the four-amps-in-one aspect of the LM324 might seem confusing at first. This Texas Instrument data sheet [PDF] on the LM324 might help clarify some questions. On the first page, you can see the pin orientation. Each op-amp is numbered counter-clockwise starting from the top-left of the IC. So op-amp #1 is 1OUT, 1IN-, and 1IN+, and so forth for each op-amp. As noted. we’re only using two amps in this circuit, or pins 1-3 and 5-7. Pins 4 & 11 are also used as our IC’s power pins, operating as the common-collector voltage and GND, respectively.

If you have any further questions about this circuit design you can always feel free to email us. And of course all these tips & tricks, pointers and other makers’ builds are highlighted in our Weekend Projects Newsletter, so if you’re not already subscribed, sign up below!

Flour-Based Flamethrower

Years ago, I posted a video of my version of the t-shirt launcher project. Recently, I retrofitted that cannon to shoot ordinary flour, which is then ignited, producing huge fire balls. The great thing about flour is that it is not flammable unless it is aerosolized, making it much safer than most other fuels. This could be a great platform for some kind of flame-belching pumpkin or other Halloween prop.

 


Scratchbuilt: Superdetailed B-24 Liberator

Without going all the way out on a limb, I’ll borrow language from my first scratchbuilt post and suggest that polish master modeler Andrzej Ziober is producing work that is approaching “the limits a single modeler can achieve,” using conventional scale modeling techniques and technologies, in the field of 1/72 scale aircraft. He has not produced many of these models, because each of them takes about five years of work, at about five hours of work a day. Mr. Ziober makes a living by writing about models and model-making in the Polish press, and much of his own published work is not available in English. The feature about him over at The Internet Craftsmanship Museum, however, is a pretty good place for English-speakers to start.

All of Andrzej’s models are built from scratch. He often favors setting them in semi-formal “repair” dioramas to show off their minute internal details, and, for whatever reasons, seems to dislike photographing the completed models with real-world objects to establish scale. For your mental reference, however, a 1/72 scale B-24 should have a wingspan just a shade over 18 inches.

Lil Ju Ju Pinball Museum: Michael Schiess (video)


Michael Schiess shows the exhibits in his Lil Juju Mobile Pinball Museum. The centerpiece on display at Maker Faire Bay Area 2011 is his vintage machine that’s been refitted completely in clear plexiglass, so that attendees can see the inner workings of the pinball machine while its being played.

“The Making of Arduino”

Very cool feature from David Kushner over at IEEE Spectrum, here quoted on the etymology of “Arduino:”

The picturesque town of Ivrea, which straddles the blue-green Dora Baltea River in northern Italy, is famous for its underdog kings. In 1002, King Arduin became the ruler of the country, only to be dethroned by King Henry II, of Germany, two years later. Today, the Bar di Re Arduino, a pub on a cobblestone street in town, honors his memory, and that’s where an unlikely new king was born. The bar is the watering hole of Massimo Banzi, the Italian cofounder of the electronics project that he named Arduino in honor of the place.

The piece goes on to describe the origins and evolution of Arduino designs up to the announcement, at Maker Faire New York 2011, of the 32-bit Arduino Due. Interesting reading! [Thanks, Sheena!]
