If you are able to make contact with these stations, you will be able to collect some of these great Tesla QSL cards. But don’t forget, you need a license to operate a ham radio.
There are a few efforts right now to try and get a list of all the open-source hardware, I think that might be impossible at this point – so lists of specific types (like music) sounds like an attainable goal :)
Joel Bukiewicz of Cut Brooklyn talks about the value of handmade, and how that extends to his line of kitchen knives that he builds in his studio in Brooklyn, New York. Joel was a writer by trade who, after taking a three month sabbatical, discovered the desire to make physical things instead. He worked with wood, jewelry, and eventually ended up making hunting knives. After finding that the knives were being displayed as works of art rather then functional tools, he switched to making kitchen knives, and catering to the New York food scene. My favorite part of the film is how he talks about moving into a work studio with others and the creativity that was fostered there.
Our own Matt Richardson is up to some fantastic things at the Interactive Telecommunications Program at NYU- check out his group project, digidrench:
A not-so-little slice of genius from Instructables user DracoGT. The legs and frame are PVC pipe and fittings, painted black. The eye is an inkjet printer transparency illuminated with an LED Tap Light. And the body, of course, is the predominant seasonal gourd, artfully cut to suggest armor plate.

In working on the builds for Weekend Projects, we’ve been dealing a lot with resistors of different values (indicated by the color bands on the resistors themselves). Trying to figure out the values of these common components can be confusing to new electronics hobbyists, so I thought it would be helpful to share some tips and tools for identifying them.
It seems like at least once a year here on MAKE there’s a “How-To Read a Resistor” post. They’re all incredibly useful in their own ways. I, in fact, use no less than four ways to read them, depending on where I am in the world and whether I’m trying to decipher a resistor’s value, or know the value and want to find the color scheme. If you’re fortunate enough to have a Maker’s Notebook, on page 162 is the Resistor Color Codes matrix. You can cleverly hack your own notebook with markers or colored pens like this so that the grid is more colorful and easier to reference. I also keep a printed-out version of this same matrix on my workshop wall, so all I have to do is look up to figure out “violet = 7″ or whatever value/color I’m hunting down. When working with beginners, I’ve found the resistor matrix to be a bit frustrating. It’s time-consuming trying to add up values in your head, and if you can’t write something down for whatever reason, it’s easy to forget. Which is why one of my favorite tools for beginners is the resistor color wheel [PDF]. I also keep a version of this pinned to my wall which I can easily spin, so when I’m looking for a 47k resistor, I quickly and easily know I’m looking for Yellow, Violet, Orange for the first 3 bands. But like I said, I have four ways to read resistors up my sleeves! The fourth is this HTML5 resistor calculator, which is incredibly handy when I’m neither in my workshop nor have my notebook with me to reference. As the name implies it only works with HTML5-compatible browsers, but all you have to do is scroll the dials into place and voila, you’ve calculated your resistor value. (NOTE: these color wheels are useful for standard four-band ‘carbon film’ resistors.)
Work with enough of the same resistors and you’ll start to memorize the color sequence and its value, but in the meantime these are some great ways to get started.

Rick Cavallaro and his team at DDWFTTW succeeded in making a wind powered vehicle that travels downwind at a speed faster than the wind itself. The vehicle is at Maker Faire Bay Area 2011, having newly accomplished a feat that was considered impossible by many. The vehicle is made from a combination of steel, carbon fiber, bicycle and windsurfing parts.
