I've used quite a variety of sound-isolating personal audio gear; around-ear cans, in-ear buds, as well as active noise-canceling models. All of these posed problems for me in one way or another. Most often, it came down to issues with comfort and how well each design could maintain a good seal on my substantial noggin.

I was excited to find out that there are custom-fit headphone services out there, but my enthusiasm withered upon learning the price for such a thing. Thankfully, I did find a DIY custom-mold earplug kit available for relatively cheap. So, I dug out my old pair of Shure E2C earbuds, ordered myself up a kit, and then put together a very simple but satisfyingly effective project.

If you're from the woods in the Northeast USA, you know that summer is all about forts, cabins, treehouses, and other alternative shelters. If you haven't known the pleasure of these delightful creations, let Derek "Deek" Diedricksen introduce you his world of microcabins in this episode of Tiny Yellow House, a MAKEcation Special Edition! Join Deek in the Massachusetts woods for a tour of his "Boxy Lady" vending cart microcabin complete with build notes inspired by his book, Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts, and Whatever Else We Could Squeeze in Here.

Gareth reviewed Deek's book not to long ago on the site:

The book is a hoot and an inspiration, crammed with Deek's designs -- from practical to pie in the sky -- for "micro-houses," small backyard retreats, kid forts, treehouses, and other no-cost/low-cost outbuildings. The emphasis here is on fun and clever use of recycled materials. Deek did all the hand-lettering and the book is obsessively illustrated with wonderfully wacky cartoons and design drawings. As he himself describes it in the video: "A carpal tunnel-inducing barrage of dime store pen sketches."

I've tried my hand at quite a few different methods for circuit building — breadboard, perfboard, custom etching, even some boardless freeform wiring, but somehow, I never got around to using surface-mount parts (until now, that is). Understandably, many balk at the idea of soldering the infamously tiny SMD packages, but once equipped with the right tools, and a bit of patience, you too can solder your own teeny-tiny circuitry.

Behold the mighty (tiny) 1206 SMD resistor - one of the larger surface mount package sizes.

As my first build in the format, I decided to go with a simple and familiar schematic — the light-sensitive oscillator (aka "phototheremin") as originally described in Forrest Mims' book Timer, Op Amp and Optoelectronic Circuits & Projects. Once I got the hang of securing each part in place for soldering, the rest of the process was more or less straightforward, and the circuit worked the first time I tested it.

Though I didn't run into any major snags, I'll likely do at least a couple things differently next time. Firstly, I used .032" diameter solder for the build, but .015" would have deposited an appropriately smaller amount of molten solder on each pad. Also, I would like to try using some sticky solder flux instead of adhesive gum, to keep the parts in place.

Happily, the SO-8 pattern protoboard I used was a perfect fit for this little test-build. A few of these boards, plus a variety of SMD parts and related tools, can be picked up as a bundle from Jameco. If you decide to have a go at building your own electronic tinyness, we'd love to check out the results!

Competitors in this year's Gowanus Studio Space Jell-O Mold Competition brought their best and really wowed the judges (including me!) on a hot night in Brooklyn last month.

The grand prize winner was Shelly Sable for her entry: Aspic Ascension-- Tastes Like Heaven. She cast several Marys in tomato aspic and the pun was complete: bloody mary indeed! Her beautiful presentation with fresh veggies had me coming back for seconds. Don't miss the video recap above, and hit the jump for tons more photos of the runners up, all by Emilie Baltz.

Well, I finally get to let the cat out of the bag. We've got Pixel Qi screens available in the Maker Shed as of today. If you're unfamiliar with Pixel Qi (pronounced "chee") and their amazing 3Qi transflective display technology, here's a bit about them from the announcement:

These screens look like standard LCD screens in ordinary room light, but take them outside in the sunlight, and see the difference! The Pixel Qi screens are bright and easy to see, even in direct sunlight. Like standard LCD displays, Pixel Qi displays show quality full-color images, full-motion video, and high screen brightness. Each pixel in the Pixel Qi screen is mainly reflective, but still has about the same efficiency as a standard LCD when backlit, enabling the user to experience a crisp image with excellent contrast and *brightness* in any light. The Pixel Qi screens consume 80% less power in the reflective mode making them a great choice for "green" applications.

Indeed, this is exciting news for anyone interested in modding their netbook or building a DIY tablet computer. Regarding the announcement, Mary Lou Jepsen, Pixel Qi's Founder and CEO said "We hope that by working with MAKE and the DIY community, we collectively will spur innovation in ways we can't ourselves imagine yet."

About carrying the Pixel Qi screen in the Maker Shed, Dan Woods (GM of MAKE Ecommerce) said "We're seeing a lot of interest in making and modding tablets, netbooks, and e-readers within the maker community, and we're always looking for new ways to help inspire and support DIY enthusiasts to take on new challenges. Getting a brand new technology like Pixel Qi's screen into the hands of developers and makers who will do something unusual, compelling, and unexpected which is really exciting to us. MAKE is not only uniquely positioned to inspire widespread experimentation within the global maker community, from educators to artists, software developers to hardware hackers, but also to organize conversations around resulting projects."

I shot a quick installation video of a Pixel Qi display going into one of my netbooks. It's an Acer Aspire One, which is physically compatible with the screen, but isn't an officially recommended netbook.

Changing the screen is easy, the process takes about 5-10 minutes using a small screwdriver. 2-4 screws have to be removed to allow unsnapping of the front plastic bezel. Once that step is done, removal of another few screws allows the screen to be unlatched and its cable disconnected. Next, the Pixel Qi screen is plugged in, screwed in, and the bezel snapped back in place. That's it.

Head on over to the Maker Shed for more information or to order yours today.

[Note: Jameco is currently offering all the parts I used in this video as a perfboard prototyping kit -- just add wire & solder. ]

When you think "DIY electronics," one of the first images that likely comes to mind is of parts and wire soldered to a standard piece of perforated circuit board -- and that makes sense. Perfboard is widely used because it's so versatile. Essentially, it's just a grid of potential solder-point connections. You can trim it down to just the size you need, or leave extra space for future enhancements, or revisions, if need be.

In this latest installment of the Circuit Skills video series, I demo my own approach to perfboarding by building a rather unusual guitar effect -- the PWM, a design I found in Tim Escobedo's excellent Circuit Snippets collection.

(For those interested, I also drew up a more traditional version of the schematic - available here.)

In order to get this thing making sound ASAP, I omitted the stompbox switch and its somewhat complex wiring. However, the optional LFO add-on seemed a bit too good to pass up, so I did incorporate that into my build.

I knew from previous projects that the 40106 Schmitt Trigger IC could make some cool experimental synth sounds. It turns out that the chip also works as a surprisingly sweet distortion pedal, if you're into that tough & spazzy fuzz-bot kind of sound (which I am). If you need a boost getting started with your layout, here's a basic diagram of all the on-board connections I made (just much neater than how I actually made 'em)

If you build a PWM, have fun! And do share build pics and impressions in the comments below.

Update: A new version of the wiring diagram (including off-board components) is now available here.

Right at the center of Maker Faire Bay Area's Expo Hall sat a 15'x24' model of an imaginary solar system. Dubbed "Fata Morgana", this elegant rotating construction of metal, motors, and light was created by Mr. Orion Fredericks - and is actually a model for a much larger forthcoming piece of kinetic sculpture.

Check out Orion's site for pics of the piece casting shadows and light on the nighttime playa of Burning Man.

On May 14-16, 2010, over 15,000 ham radio enthusiasts gathered for the annual Hamvention in Dayton, Ohio. From the moment I drove up behind the creator of APRS (GPS for ham radio) there was something radio-related to see. It was like ham radio's Maker Faire. I've captured some of the highlights in this video.

There were demos of Arissat-1, a homemade satellite from AMSAT. Morse code keys of every kind were scattered throughout the convention space (touch sensitive and bugs). There were tons of electronic parts, including component jewelry. I saw an aerial balloon being launched and met the president of the ARRL, Kay Cragie.

Throw your Povard in the air. Then wave it like you just don't care! Everyone will be able to read your message loud and clear. The Povard is a large hand held POV device that is built onto a very cool laser cut and etched acrylic bezel. A POV "tricks" your eyes into seeing a full image when only part of the image is visible at one time. This effect is called the "Persistence Of Vision." This is the way the Povard works. As you move the Povard you will see one slice of each letter at a time. Your brain assembles all the slices together for you to be able to see a complete word or image.

Note: An Arduino is required (and not included) for programming the Povard

Mobile radios are like DIY cellphones. They can communicate across the world without the infrastructure of cellphone carriers or the internet. And sometimes, there's a lot of satisfaction in being able to do something all by yourself.

Here I am at Hamvention 2010 in Dayton, Ohio checking out all of the mobile radios. There was everything from pedestrian mobile, to ham radio backpacks, to bicycle mobile.

I met Kent Weakley and his son Lucas at Maker Faire this year -- a couple of really nice guys who got there a day early (as Maker Faire Boosters) for a look behind the scenes. Lucas helped me put together some of my projects while Kent set out with video camera in hand to capture the sights and sounds of the Faire over the next two days.

After the Faire was over I got an email from Kent:

Hi John, Here's the video from last weekend. Hope you like it. Lucas is on cloud nine still from Maker Faire. I can't help but think this is a movement that will help establish a whole new generation of creators who might not have otherwise been inspired to do so.
