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 through graphic novels

Images I 41Ajppqs6Fl. Ss500
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.
Michael Keller - Journalist, Author, "Charles Darwin's On The Origin Of Species: A Graphic Adaptation" (Rodale Books, 2009) 
Apostolos Doxiadis - Co-author, "Logicomix: An Epic Search For Truth" (Bloomsbury, 2009)

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!

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!]

Make: Projects - Pneumatic trough, part II

image from golden book of chemistry experiments page 28.jpg

Last week I wrote about how to construct a simple sheet metal "bridge," which, in combination with an ice cube bucket and an olive jar, makes an effective pneumatic trough for collecting gas samples over water. This week I'm going to show you how to use this apparatus to generate and collect pure oxygen, and how to use that oxygen to observe the brilliant blue flame of sulfur oxidation.

Tools:

Pneumatic trough apparatus from part I
Small piece of plate glass (I used the mirror from a makeup compact)
Lighter
Twisted wire sample loop
250 mL Erlenmeyer flask (I got mine from The Maker Shed)
#7 two-hole rubber stopper to fit Erlenmeyer (mine came from this assortment)
Two 80 mm lengths of 5 mm glass tubing to fit stopper (such as this)
Approximately 18" length of 5/16" OD x 3/16" ID PVC tubing to fit glass tubing (common hardware store item)

Materials:

Water to fill bucket
Elemental sulfur powder (also called "Flowers of Sulfur," available at some drugstores and here.)
3% hydrogen peroxide (common drugstore item)
Manganese dioxide (can be recovered from an alkaline dry-cell battery or purchased here)
Petroleum jelly (drugstore)

Cardboard tube battle

My local library picked up on the festive trend of Cardboard Tube Fighting. The Boston Globe covered the preparations:

The group discovered cardboard tube fighting last summer in time to incorporate a bit of it into a presentation on Greek mythology at a reading program party.

The weapons are cylindrical pieces of thick cardboard about 4 feet long. The appeal, explains young-adult librarian Ellen Snoeyenbos: "It's totally ridiculous.''

As word of mock combat with reliably harmless weaponry spread among the town's youthful warriors, Snoeyenbos and the Bookmarks seized on the fund-raiser as a chance to exploit their discovery of the fighting fad made popular by YouTube.

Saturday's event will feature one-on-one tournaments, guild-on-guild skirmishes (up to 10 fighters per team), "and an all-out battle for possession of the Royal Crown,'' according to the club.

They've gathered hundreds of tubes, and youth of all ages are uparmoring in a pulpy way.
