Cigar boxes are great containers for loads of things. I had a bunch on hand after going to the local wine shops and asking for donated cigar boxes. Inspired by the Rock and Roll Speakers project in Fashioning Technology, it seemed like a good idea to have my students build their own music player embedded in a cigar box. This is a major project, taking several weeks, though it probably could be done by an individual in an afternoon without introducing many of the concepts we've worked on.

Box preparation
The boxes are pretty well made, and we found that we could sand them and coat them with spray paint. Boxes with colorful printed designs can be left unpainted. We have a vinyl cutter, so a lot of class time has gone into making custom multicolor stickers from photos. We're using the Threshold tool in Gimp to convert the image to a high contrast black and white, and then importing it to Open Office Draw to add a border. Having a border makes the sticker weeding process much easier.

Speaker insert
Using some scrap cardboard a metal ruler, utility knife, and careful measurement, we made an insert to hold the speakers and cover up the electronics. The speakers sound much better when enclosed. Just putting them inside the box improves their sound even without the cardboard insert. The speakers are secured to the cardboard with hot melt glue, and some students are making speaker grilles for further protection.

It's not often something stops you in your bike tracks. But a spectacular "bike tree" invention from Japan bowled me over when I was in Tokyo a couple of weeks ago.

Fed up with bicycles locked to railings, piled on top of each other, blocking doorways and roads, a local council in the city installed the mechanical masterpiece. It's basically an automatic storage system for cycles and operates with computer tagging of bikes and either storage in a building or a basement structure.

There are a number of locations where these bike trees are now in place in Tokyo – some hold 600-odd bikes, others more than 6,000. The concept came from the massive Japanese steel company JFE, whose engineering works division first started them in 2007 but are now spreading.

One problem with making lots of neat projects is that you need a place to display them. And, where could be better than on a table that you built yourself? A nice place to start might be this tutorial on building a folding table, by the folks at HandymanWire. I like their design because it can be made from a single piece of wood, and because it can be folded for storage or easy transportation. [via curbly]

My daughter had to draw first blood on the package. We cracked the box and checked out the stuff inside. After going to the hypnotist show to benefit the school drama department and doing strange things on stage, I felt refreshed and motivated to assemble and play with Chumby guts until long past my bedtime.

I didn't take any photos, in large part because of the very helpful images already taken and posted to the MAKE Flickr Pool.

Build instructions are on one double sided sheet of paper. I missed it the first few times I looked through the box because I thought I would find a booklet. There is a link to the instructions pdf on the Chumby guts page in the Maker Shed. The directions are pretty good, but leave a bit to be desired. I found the photos by MAKE Flickr Pool members MTBFO and ewee to be essential. Early in the build, I was wondering which of two sets of small screws to use, and found that the silver ones were likely the ones by checking a photo. I also found the notes on many of ewee's pictures to be really useful.

So now there is a new tooltoy in the arsenal. This should be fun, and already the big question is "How do you case this thing?" Kent Barnes has extended the chumbilical cord that connects the mother and daughter boards and seems ready to move things around. John Park has a nifty laser-cut case. The box that it came in is sized about right for a first enclosure. The next case will probably be a cigar box, which is very alluring lately. You can clothe your naked Chumby guts by following these instructions.

As soon as it was plugged in, the disembodied Chumby woke up, started talking and showed a tour of the basic functions. Within a few minutes, it had upgraded the firmware and brought me to the website to register it. Finding the household wireless was a snap. Over on the Chumby wiki, you can find resources on hardware, software, and more.

In all, this has already been a fun project with few pitfalls. The next steps of customizing the case and configuring the software are exciting prospects at this point. Now that she's awake, my daughter is curious about how each of the widgets work. This will be a fun thing to have.

Have you got a some Chumby guts waiting to be animated? If you've already built yours, please weigh in with your tips and tricks by adding a comment or two. If you have a glamour shot to share or process set of pics, post them over to the MAKE Flickr pool.

The design of the Brainwave Sofa is driven by a brain scan. Brain wave activities are being recorded by an electroencephalograph by placing electrodes on the bare skin on the head. Via BioExplorer, a computer program that records biophysical data, processes and visualises it, a three dimensional waved landscape is generated. The x-axis shows the brain wave activities in hertz. The Y-axis shows the amount of activity in percentage. The Z-axis is the time expressed in milliseconds.

Craig Smith sent us these pics and note:

My telescope is low end in the scope-world, a 60mm refractor. But I discovered the eyepiece is the same size as my digital camera telephoto lens. My digital camera is low end in the camera world, too, a 3.2MP. But put them together with a custom PVC sleeve aligning lens-to-eyepiece, and I'm getting awesome moon shots. Here is the moon on 11/5/09. I added a camera support arm also, a quick adjustment of the tripod leg's wing nut, and I'm all aligned to photograph the skies.

In partnership with the OpenOffice.org community, WarMouse announced the release of the OpenOfficeMouse, the first multi-button application mouse designed for the world's leading open-source office productivity suite. With a revolutionary and patented design featuring 18 buttons, an analog joystick, and support for as many as 52 key commands, the OpenOfficeMouse is intended to provide a faster and more efficient user interface for OpenOffice.org applications such as Writer and Calc than the conventional icons, pull-down menus, and hotkeys presently permit.

"You can do far more with this mouse than most people are likely to realize at first," said mouse designer Theodore Beale. "You can launch applications from the desktop, and in your browser you can fire up a specific Internet site with one button, then close it with a double-click on the same button. In Writer and Calc, you can have your most powerful and complicated macros on one row of buttons and simple functions like Bold, Undo, and Format Cell on another. It's very useful in games like World of Warcraft, because even without taking the joystick into account, you've got 16 commands within one click, 40 within two, and all 72 icons on the six action pages within just two double-clicks or less."

Martian landscapes - The Big Picture @ Boston.com via Waxy.

Since 2006, NASA's Mars Reconnaissance Orbiter (MRO) has been orbiting Mars, currently circling approximately 300 km (187 mi) above the Martian surface. On board the MRO is HiRISE, the High Resolution Imaging Science Experiment camera, which has been photographing the planet for several years now at resolutions as fine as mere inches per pixel. Collected here is a group of images from HiRISE over the past few years, in either false color or grayscale, showing intricate details of landscapes both familiar and alien, from the surface of our neighboring planet, Mars. I invite you to take your time looking through these, imagining the settings - very cold, dry and distant, yet real. (35 photos total)

Yesterday we sent out our second issue of the new Make: Newsletter. It contains news of goings on at Maker Media, several original columns (including the second installment of my Maker's Dictionary column), and special Shed and magazine deals for newsletter subscribers only. Next month, we're even going to launch a mini-projects column.

You can subscribe (free) to the Make: Newsletter here.

Wish you had a skylight, but don't have the ability to cut a hole in your roof? MAKE subscriber Chris did to, and wrote in to share his solution to the problem: a pv+led-based 'fake' skylight. The concept is pretty simple, but with a nice result. He had some unused capacity on his PV (photovoltatic) solar panel, and basically hooked up a bunch of high power LEDs directly to it. To achieve the 'skylight' look, he built a custom metal box with a glass diffuser screen, and mounted the diodes inside of it. He has a nice write-up on his site, along with a calculator to determine how the LEDs should be connected. Excellent work!

This work by sculptor and musician Bradley N. Litwin, of Philadelphia, is called "The Octapult." In his words:

With 8 synchronized catapults, 160 plastic balls per minute are launched, caught, and recirculated. Made mostly of wood, the work is ~36 inches in diameter. On permanent display in the lobby of Lower Merion Elementary School, Merion Station, PA.

Want to claim your city as your own? Competing with a rival gang for turf, and want to avoid messy knife fights? Well now you can, thanks to Urban Defender. Working over a short time period, a team of students from Zurich University of Arts built a system to claim buildings by throwing a specially equipped ball at them. Impacts are detected by an accelerometer connected to an Arduino, which is wirelessly connected to a Beagle board which uses a GPS to coordinate the hit to a specific address.

They apparently didn't have time to finish the multi-player version of the game, but I think the concept is too good to let die. Someone should definitely hook this up to the social networking game foursquare. As a bonus, you could use the sensor units to play the actual game four square when you get tired of fighting for turf.

Look, Ma, it's a motorcycle with four wheels. Not a bike but, um... a "quike," maybe? It's the 4RWF V8 from "Cosmos" Muscle Bikes. ("Cosmos?" Really?)

Usually I write about ham radio. But looking at communication devices of the future from the past, I thought it would be fun to have a Star Trek: The Original Series Bluetooth communicator for a cellphone. I worked with Dave Clausen to hack one together from a toy Star Trek communicator, a Bluetooth module, and a microcontroller. Following are the directions and program to make your own. And of course a video to show how the Star Trek Bluetooth Communicator works.

And if you really want to geek it up, the Star Trek Bluetooth Communicator can also be used with the Yaesu VX-8R ham radio. It also makes an awesome gift. Read on for the full tutorial.

A reader just sent me a link to servodatabase.com, which lists RC servo specifications and provides user reviews, a comparison engine, and various forms of sorting. Looks like a very good resource. [Thanks, Phil!]

Oh wow, it's the Cupcake CNC kit from MakerBot Industries! I'd ordered it weeks earlier and had completely forgotten about it. (The truth is out: I have an atrocious memory, sad but true.)

And so the adventure begins! I'm going to document my "out of box experience" with a MakerBot. How many posts will the series be? I'm not sure since I've never built one. How often will I post about the build? Again, not sure, but I'll try to do at least one a week, maybe more, it all depends on how much free time I have between all my other maker-ly projects.

A little background: My CNC experiences

I've been tinkering with CNC for about 10 years, and consider myself an enthusiast, not an expert. I do own a few CNC mills, routers, and lathes. I have retrofitted old mills, and even build one from scratch. Pictured above is my mobile CNC machine, dubbed the "MobileC." I stuffed all the components into a mobile tool cart so I could bring it to hackerspaces, workshops, and events, all in the hopes of helping out fellow makers.

SUCCEED Blog: "A collection of the world's most epic, awesome, mind blowing Succeeds"

For folks interested in the intersection of arts and science, the PBS series Independent Lens is presenting a fascinating in-depth look into origami titled Between the Folds. The film documents "a determined group of theoretical scientists and fine artists who have abandoned their careers and scoffed at their graduate degrees to forge new lives as modern-day paper folders."

Featured in the film are MIT's youngest-ever tenured professor Dr. Erik Demaine; mathematician, sculptor, puzzle maker, and self-taught computer scientist Marty Demaine; master free-style folder Vincent Floderer; pioneering Israeli educator Miri Golan; mathematics professor Dr. Tom Hull; trained artist and instructor Paul Jackson; one of the most technically accomplished folders in the world, Eric Joisel; one of only a few handmade origami papermakers in the world, Michael LaFosse; origami "hyper-realist" and physicist Dr. Robert J. Lang (who was profiled in CRAFT Volume 05); material artist with a masterful understanding of patterns and geometry, Chris K. Palmer; and the father of modern origami, Akira Yoshizawa.

Screenings are part of the Independent Television Service's (ITVS) Community Cinema series, which are free, followed by discussion panels and access to resources.

Between the Folds will be showing in the Bay Area in Oakland on Tuesday, November 17 at 6:00 p.m. at the Oakland Asian Cultural Center and in San Francisco on Wednesday, November 18 at 5:45 p.m. at the San Francisco Main Library. For a list of screenings taking place across the country, check out the film site.

Here are a couple of interesting excerpts from the documentary to get a flavor for it. The following clip features Paul Jackson, an origami artists and art teacher living in Tel Aviv, Israel, speaking of the "one fold":

And this clip shows Michael LaFosse, a master artisan who not only makes origami, but is one of the only handmade origami paper makers in the world, providing a window into his workshop and processes:

Mark Frauenfelder and Dan Woods got sent this letter about the latest issue of MAKE, Volume 20. We got the sender's permission to post it here:

Mark and Dan,

This is Jim Kelly, the freelance tech writer in Atlanta. Hope you guys are doing well.

Just wanted to write and tell you how impressed and inspired I am with issue 20 of MAKE magazine. The interview (and foreword) with Adam Savage was extremely fun to read. As a father of a 2.5 year old, I too am anxious to encourage my son to explore, take apart, design, and enjoy the creative process.

Issue 20 was directed at kids, and I think you hit the bullseye, with force behind it. I hope this issue is one of your bestselling ones, and I for one am encouraging parents I know to pick up a copy. I'm also purchasing a few extra copies for some teachers I know.

My son just got done watching me configure my new CNC machine to mill out some fun designs on wood; his eyes could not have opened any wider. I wish all kids could have access to this level of technology and machinery, but unfortunately, our school systems seem to be cutting shop class and art projects and focusing time and money on standardized test-taking skills... how unfortunate.

To bring this all home, I guess what I'm trying to say is that there is such a demand for material/content that encourages our youth that a void has been created and cannot be filled fast enough. MAKE is in a unique spot to develop something that goes a little beyond the Maker Shed and the quarterly magazine. Maybe it's a subscription-based activity website, with monthly special projects broken down into categories such as "Do It Yourself" (no parents required), "Dad and Me" (or "Mom and Me" - projects with the parents), and more. Maybe it's a special magazine (like your Halloween special issue) that focuses on even more kid-friendly content. Or maybe a mixture of projects and inspirational interviews (Dean Kamen comes to mind) in a book format.

I'll wrap this up by saying that I, Jim Kelly, hate the three month wait between issues of MAKE... I read every issue over and over again. I'm starved for this type of content. And I'm an adult - imagine what those kids who have this creative streak inside them must feel? They're in need of something... not sure what... and maybe you guys can figure out what to offer them. Issue 20 could easily be just the tip of the iceberg.

Take care,

Jim Kelly

Thanks for your thoughts and kind words, Jim. Reaching the educational market, be it home-schooling parents or teachers in grade school and college, is an increasing focus of ours. We see the new Make: Science Room as part of that effort. We also have the Make: Education social network to reach out to educators and and to create a place where they can network with each other. We've also been working on a dynamic new project-based program of making and mentoring designed to raise the next generation of makers. We're developing this with some very innovative, high-profile partners and are very excited about the prospects. Stay tuned -- we'll be making an announcement about this in the next few months and looking for some kids to participate in a pilot program.

We'd also like to point out that there is something to tide maker parents, kids, and educators over between issues of the magazine: this website, Make: Online! Over the past year, we've been adding much more original content, regular columns, weekly projects, guest authors, and special programs. And then there are our regular Weekend Project podcasts, and special videos, like Collin Cunningham's MAKE Presents series, and Marc de Vinck's how-to and kit build videos. There's a lot going on here, so we hope you're getting your daily dose of MAKE from us. If there's anything else you'd like to see us do here to satisfy your MAKE fix, please let us know. We're always looking for ways to expand and improve the site.

From the pages of MAKE:

Want to know how to build a hydrogen rocket? How about a laser light show in a lunchbox? Or a simple remote-controlled videocam car? Or maybe you want to go old-school and build a wooden mini sailboat or toy car launcher? All this and tons more, plus revealing photos of Adam Savage's maker childhood, can all be found in MAKE, Volume 20, "For Kids of All Ages." Get your individual copy in the Maker Shed, or subscribe now.

On Saturday, I'll be stopping by the new hacker/maker space called I3 Detroit in Royal Oaks, MI. I'll be there from around 11 am to 1pm (give or take a half-hour). If you are a maker in the area, and don't mind giving up some time that you might otherwise spend on your favorite project, please drop by I3 Detroit and share your thoughts on doing a Maker Faire in the Detroit area. I am always looking to discover new makers and learn more about cool projects -- at home, in schools, or even at work. I am also proud to talk about our new "kids of all ages" issue.

I3 Detroit is located at 322 East Fourth Street, Royal Oaks, MI.

We're using a hazer to make the laser beams visible, which works surprisingly well in this semi-open space. To increase the spectacle we installed a few extra lasers that are not being sensed for tripwires, but just look cool. The heisters won't know which these are, however, so it adds to the challenge without increasing complexity.

In this side view you can see what happens when you break too many beams: lots of lights come on, including a blinding, red LED array. For this Tod used an Arduino-controlled AC optical relay. I'm hoping Tod will write up the whole project for a MAKE article, because he has all kinds of neat tricks like this throughout.

The event is shaping up to be truly wonderful, and affords the attendee a rare chance to hang out in Mister Jalopy's secret underground lair. I'm totally shameless, so if you ask I'll eat some laser for you. There are still a few tickets available, hope to see you there!

A bird dropping a piece of bread onto outdoor machinery has been blamed for a technical fault at the Large Hadron Collider (LHC) this week which saw significant overheating in sections of the mighty particle-punisher's subterranean 27-km supercooled magnetic doughnut.

According to scientists at the project, had the LHC been operational - it is scheduled to recommence beaming later this month - the snag would have caused it to fail safe and shut down automatically. This would put the mighty machine out of action for a few days while it was restarted, but there would be no repeat of the catastrophic damage suffered last September. On that occasion, an electrical connection in the circuit itself failed violently, causing a massive liquid-helium leak and knock-on damage along hundreds of metres of magnets.

I love this. Instructables user wholman has gathered together a bunch of scrap wood from "dumpsters, back alleys, vacant lots, abandoned buildings, recycling yards, and architectural salvage centers" and laminated it together using all-thread. Then he's very carefully smoothed and polished only one side of the finished block, leaving the underside rough to show off the process. Beautiful.

Ian writes in:

I was looking at buying a digital camera, and read that there are two kinds of sensors that they can use to take a picture- CMOS and CCD. Can you tell me what the difference is, and if one is better to get?

Sure! It's actually a pretty topical question, as the inventors of the CCD just won this year's Nobel Prize! As you mentioned, there are two basic kinds of image sensor that are used in today's digital cameras, CCD (charge-coupled device) and CMOS (complementary metal oxide semiconductor). They both work by converting light energy (photons) into electric charge (electrons), and the difference is in how this charge is read out.

To start, both kinds of sensor are made of a grid of 'buckets' placed evenly across a flat semiconductor surface. Each bucket acts as an individual sensor, which only sees a tiny portion of the image. By displaying a bunch of these tiny points in a grid (using a computer monitor or printer), we see the image.

Making color images is a bit more complicated. Because the buckets are sensitive to any wavelength of visible light, if we just looked at the results we would see a monochrome image. To get color information, we arrange the sensors into groups of four, and place tiny red, green, and blue color filters over them. Each group of four sensors is what we call a pixel, and it is interesting to note that modern cameras have millions of them.

Ok, so both CCD and CMOS sensors are basically just big arrays of individual sensors, so how are they different? The difference is in how the charges are collected and read out. In a CCD, the 'bucket' that collects charge is just a capacitor. To read the image data out of the CCD, the charge in each bucket is pumped individually over to an ADC (analog to digital converter), which actually measures charge. In a CMOS sensor, each bucket contains a photodiode and some amplifier circuitry. To read the image data out, the output of each amplifier is connected to an ADC through a multiplexer, which measures the voltage at each cell.

I don't think that either technology is necessarily better, but each has its own quirks. There is an interesting site at dvxuser which talks about the different kinds of sensor artifacts associated with each kind of sensor. For most cases, though, I think that other specifications, such as ease of use and sensitivity to light, are probably more important to think about when choosing a digital camera. Good luck!

Interesting article in the Telegraph about "Argleton," a town that appears in Google maps but does not, apparently, exist in the real world. The best theory I've heard is that the town is a "trap" intended to catch those who steal map data. [Thanks, Glen!]

Anybody else might shrug off these ice spikes as a meaningless hiccup in the preparation of a frosty beverage, but not Lenore and Windell at Evil Mad Scientist Laboratories!

Snowcrystals.com has a fairly detailed explanation of how these things form, and it's documented elsewhere as well. (Roughly speaking, supercooled water is pushed up through a hole, somewhat like magma forming a volcano.) It's relatively easy to form these in your freezer if you start with distilled water, but occasionally-- as in our case --they do occur with regular tap water.

Care to hand control of your playlist over you to an Arduino?

Awhile back I was working on a project that that I wanted to be able to start music the on my mac through the IR receiver. After a while of looking around I found this library  which allows you to use your arduino as an Apple Remote. I integrated it in to my project and it worked great! So the other day I decided to make an Apple Remote shield for my arduino.

You can get 'em from the Evil Mad Scientist Laboratories webstore. Update: Also available from The Maker Shed.

The user interface to the R1 radio is both familiar and unique. Roll up and down for volume or scroll left to right to tune. It's brilliant in its simplicity and rather stylish in a contoured minimalist design. [via GeekyGadgets]

An analog radio is one of most important product for a blind people. In the using a behavior of how people manipulated rather than burying all of interaction in to the product. So adjusting radio to the right station would require a new kind of manipulation rather than simply tuning a knob. 'R1' has designed for them to control the radio more intuitively. By using a wheel structure user can control the radio by physical movement. The 'R1' allowed users to turn gadget on or off and to control volume and tuning simply by physically rolling the radio forward, backward and sideways.
