BlueSMiRF found in credit card sniffer

Pt 2338
SparkFun BlueSMiRF found in credit card sniffer, interesting Sparkfun product placement. Nate writes -

That is an officer of the law holding up a device that was found within a 'PIN pad' in Waterloo, Ontario, Canada. I didn't know what a PIN pad is, so here's a wikipedia article and google images. From the article (November 5th, 2009), it looks like someone has found a couple serial pins on the hand-held credit card reader commonly used within Canadian retail stores. They've wired those pins to a BlueSMiRF. This allows a person sitting ~100 feet away to see all the serial traffic including all the credit card information and pin #s. Not hard - all it takes is a bit of time, and malicious intent... All things can be used for good or evil, including our products. You can build amazing things that encourage children to learn (checkout Gever Tulley's amazing presentation at TED), or you can build things that steal. We believe that sharing knowledge and selling products that encourage innovation outweigh the inherent dangers. We believe that stifling innovation or suppressing knowledge lead to much more dangerous outcomes.

Thing about this scam is that the person(s) who modified the device needed a lot of access to the device(s) and then they need to hang around 100ft away all the time... inside job? Either way, the more this story gets out the more people will know about it.

New in the Maker Shed: Microbe Motel kit

The Microbe Motel is the grossest, smelliest, nastiest science kit we've ever offered. Ever! Other than some common household items, the Microbe Motel includes everything you need to grow colorful, stinky, colonies of household germs, bacteria, molds, and maybe even a fungus or two. Don't worry, you can kill them when you're finished.

Here are just a few of the experiments and projects you can do with the MAKE Microbe Motel Kit.
Are dogs' mouths really cleaner than human mouths? Culture bacteria from your mouth and your dog's mouth to find out.
Is the average toilet bowl really cleaner than the average kitchen sink? Find out by swabbing both and culturing the bacteria.
Find the grungiest areas in your home by swabbing and culturing your computer keyboard, television remote, telephone, etc.
Is money really as filthy as your grandmother told you? Find out.

Science Friday's "Science Through Graphic Novels"... Great interview(s)! Using graphic novels to teach science...

In this segment, we'll take a look at two graphic novels that approach science from a different direction. One tackles Darwin's 'Origin of Species,' while the other deals with the life and ideas of philosopher and mathematician Bertrand Russell.

Maker Shed kiosks at Fry's

We're ecstatic about the fact that we now have Maker Shed kiosks, with magazines, books, and electronics kits, in several California Fry's stores. We think this is big news, not only for Maker Media, but for all indie makers -- a major retail chain is now giving small kit-makers this level of exposure. And, we think it's particularly cool that we designed and built these kiosks in-house, and even personally delivered them to the stores! What other publisher could claim that?

Here, Assoc. Publisher and General Manager of Maker retail, Dan Woods explains more:

Maker Shed kiosks are now installed in four of Fry's largest superstores. Each kiosk merchandises current and back issues of MAKE, Make: Project books, and kits, with an emphasis on maker-made kits produced by indie makers like Limor Fried's MintyBoost, Mitch Altman's Brain Machine, Ken Murphy's Blinky Bugs, Dale Wheat's Tiny Cylon and Wee Blinky kits, and Amy Parness and Ariel Churi's DIY Design Electronics kits. This indie maker angle was a really important selling point to Fry's. The kiosk's themselves are all-MAKE in their design and construction. The challenge was to create a merchandising/branding kiosk that could show off maker-made kits, as well as our books and magazines, all in a 2' X 2' footprint. The design we came up with incorporates the Maker Faire workbench framing as the internal structure, refurbished fence boards from West Sonoma, and some nicely weathered corrugated shed aluminum that was locally salvaged. The result is a nice combination of weathered shed and repurposed industrial tubing. They're uniquely MAKE, and Fry's is ecstatic. In fact, they were even trucked down and setup by Heather (Harmon-Cochran) and Rob (Bullington) in one day.

These are the stores that currently have kiosks. (San Diego will be set up by Fry's staff next week)

New hackerspace in Chicagoland: Workshop 88

Good news for those in Chicagoland! Planning is underway to form Workshop 88, a hackerspace in the west suburbs of Chicago. Here's your chance to get in on the ground floor!

We're currently in the planning stage, and we're looking for interested people in the area to help us get started. We're holding bi-weekly meetings Mondays at 6:30 until we're ready to rent some space and move in. The first meeting is this Monday, November 23, at the Boilerhouse Cafe, on the campus of North Central College in Naperville (29 N Loomis St Naperville, IL 60540).
Some of the things we'll be discussing:

Legal structure of the hackerspace

Membership structure and guidelines

Work that still needs to be done to build out our online presence

Current projects

This information is also available on our blog, at http://blog.workshop88.com. Updates and meeting notices will be posted there, as well as on Twitter at http://twitter.com/Workshop88. For additional information, we have a mailing list at info@workshop88.com.

Mint tin electronics dev kit packs the essentials

From the MAKE Flickr pool

Once you've caught the 'electronics bug', spending time away from the workbench/lab can seem an unpleasant prospect. Luckily, one can carry on learning and experimenting with a minimal amount of hardware. Nick shares his own recipe for ultra-compact electronics prototyping - the Altoids Tin Electronics Lab

This is a small electronics lab in an altoids tin. It contains nearly everything to work on small projects, such as a breadboard, components (including several ICs), and a adjustable power supply. The power supply is a simple LM317 circuit, with the 317's metal tab cut off to make it fit.

For details, check out Nick's essential part list. I'm guessing quite a few of us have mobile kits along these lines. Share pics of your setup via the MAKE Flickr pool - we'd love to see 'em!

Building a shop presence notification system

As a member of Hack Pittsburgh, our local hackerspace, one thing I've wanted to know if anyone else is there before I make the trek over. Well, so did Andy Leer and Marty McGuire, so they decided to build a shop presence notification system. They reasoned that they could measure the ambient light level to determine if someone was around, because people tend to turn on the lights when they show up. With this in mind, they hooked up a photocell to a donated iobridge module, and had a notification widget up on the website in record time. Excellent work!

Free LED Cookbook from TI

Vacuum tube prototyping board

Bruce Heran made this prototyping board for his tube projects. He writes:

This is a project that I made to take care of an ever increasing need to prototype vacuum tube (valve) circuits. As you can see from the photos, it really is a test "board." I do a lot of work with tubes and love to design and improve circuits. In the process I often use various CAD type programs to rough out the designs. I have frequently found that the models do not agree with the final build. Some are right on, but most are off enough to turn a good idea into a waste of time. Thus the need to quickly prototype designs. Now I could have created this board with many additional features - speakers, output transformers, LEDs... But what I needed was a simple way to test single stage tube circuits. So for simplicity I wired the tube pins together (pin 1 to pin 1 and so on). The leads from the pins are brought out to terminals on a "Euro" style terminal strip. I included several other "Euro" strips, a pair of RCA jacks, a 100 k-ohm variable resistor and solderless prototype breadboard. This solderless breadboard is available in various sizes from several sources. If you build one of these boards, feel free to use the idea to adapt it to your needs and use whatever parts you so desire.

[Thanks, Gio!]
