Tuesday, April 22, 2014 - 23:00Make Your Own Battlestar Galactica Sidearm Replica
Even though I look at tons of cosplay stuff, I sometimes forget that anything can be fashioned from PVC foam (Sintra is one option). Instructables user Goombah Squad used the material to make some cool Battlestar Galactica guns to go with his costume. After he purchased blueprints from another builder, he used the foam to piece together the gun. After that it was all abut the shaping. Here’s the steps he took to get the gun just right:
I use a Dremel with a sanding bit for 80% of the work. The remaining 20% is a variety of needle files, various grits of sandpaper, or the occasional grinding and engraving bit. I started by shaping and gluing the main frame of the gun. Once everything was how it needed to be, other pieces were added: grips, various rails along the side of the barrel. The two halves of the slide action were each crafted separately. So was the grenade launcher attachment.
Once everything’s shaped, break out your Bondo. Bondo is an automotive filler typically used to fill in car dents and dings but as you’ll find, it’s widely used in propmaking. Anywhere you see unsightly seems or low areas, mix up some Bondo. Wait about 20 mins for it to cure when it becomes unworkable.

Tuesday, April 22, 2014 - 22:002048: Embedded Edition
How ’bout that 2048 game? Pretty addictive, huh? Almost as addictive as embedded systems are, at least if you’re [Andrew]. Armed (pun intended) with a Nucleo F4 and a Gameduino 2 shield, he decided to have a go at making an embedded version of the popular tile pusher web game.
If you’re unfamiliar with the Nucleo boards from STMicroelectronics, check out our post on the Nucleo family from a couple of months ago. The Gameduino 2 shield ships with a 4.3″ touchscreen driven by an FT800 GPU EVE. [Andrew] wrote his own driver for it and his blog post goes into great detail about its programming model and the SPI read, write, and command functions he wrote. Full code is available from [Andrew]‘s repo.
He started by generating a blank screen based on clues found in the Gameduino 2 source. Pretty soon he had rendered a rectangle and then a full 2048 board. A minor difference between [Andrew]‘s creation and the original is that his always creates new tiles as ’2′ while the web game cranks out the occasional ’4′.
We were unable to embed [Andrew]‘s gameplay videos, but you’ll find two on his blog.

littleBits is an opensource library of electronic modules that snap together with tiny magnets for prototyping, learning, and fun.
littleBits (spelled lower case L, upper case B, all one word) consists of tiny circuit-boards with specific functions engineered to snap together with magnets. No soldering, no wiring, no programming, just snap together for prototyping, learning and fun. Each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits. Just as LEGO™ allows you to create complex structures with very little engineering knowledge, littleBits are small, simple, intuitive, blocks that make creating with sophisticated electronics a matter of snapping small magnets together.
With a growing number of available modules, littleBits aims to move electronics from late stages of the design process to its earliest ones, and from the hands of experts, to those of artists, makers, students and designers.

Phillip Stearns’ glitch textiles are the result of “transcoding glitches in the cold, hard logic of digital circuits into soft, warm textiles. I wanted to find ways to give digital and computer-generated images life beyond the screen.” The design for this cotton throw was created by manually short circuiting a low-resolution digital camera, then made using computerized weaving and knitting machinery.
Tuesday, April 22, 2014 - 20:00A Collection of Comic Maps #arttuesday
Last week, Hyperallergic highlighted the great work being done on the blog Comic Cartography, which has an extensive catalogue of graphics and maps taken from comics. Hyperallergic’s Jillian Steinhauer writes about the importance of these maps in the fictional world building of the comic book genre:
Comics are an especially apt medium for this type of construction, since, well, they’re visual. Diagrams and maps in comics can do different kinds of work: they can be used as exposition, to help readers get their bearings in a story, or to create a mood or feeling, or simply as a prop. They’re not even necessarily made-up — Jason Lutes’s Berlin is a series of fictional stories set in a historical place.
Comic Cartography, a lovely blog that I discovered today, collects images of maps from all different kinds of comics, from Lutes’s Weimar-Era Berlin to the office layout of the Daily Bugle, the fictional newspaper featured in the Spider-Man comics. The wide range of work makes the blog engrossing, as it highlights the many forms and shapes that maps can take but also their underlying commonality: we use them to make sense of the world, even if that world exists only in our heads. To that end, there’s also something wonderfully meta about seeing these images within images — they seem to simultaneously represent a homing in and a zooming out.

Tuesday, April 22, 2014 - 19:01Retrotectacular: The Science of Derailing Trains
Look closely above and you’ll see there’s a section of track missing. There are actually two, a section from each side has been plucked out with a pair of eight-ounce plastic explosive charges — and yet the train keeps barreling onward. The World War II era reel is demonstrating some military testing of the effect of damaged tracks on a train. The amount of missing track the train can stand up to came as quite a surprise for us!
The test setup itself is neat. An old derelict locomotive is used. It, as well as a number of trailing cars, is pushed by a functioning engine from behind. Once up to about 26 MPH the pusher stops and the rest keep going. There are many tests, starting with just a few inches of track missing from one side. This gap is increased, then gaps are added both sides, then the two sides are offset. Even a 5-foot gap is crossed easily by the locomotive. The weak link turns out to be the empty cars. We suppose their mass is small enough that they can’t rely on inertia to keep them on the straight path.
If you don’t appreciate the destructive nature of this Retrotechtacular installment, you can still get your train fix. There is another offering which shows off the modernization of a signaling system.

Tuesday, April 22, 2014 - 18:32Happy Earth Day 2014! Here’s some giant images of the Earth via NASA #earthday2014
Today is Earth Day! Every year we celebrate by posting some of our favorite images of the earth. These are from the NASA catalog called visible earth. You can view more images here. Here’s a little background on the history of earth day:
Earth Day is an annual event, celebrated on April 22, on which events are held worldwide to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.
In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature’s equipoise was later sanctioned in a Proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom Award in recognition of his work. While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues.

Tuesday, April 22, 2014 - 16:00Autodesk Updates 123D Design for Desktop #3DPrinting
Just when we weren’t sure if Autodesk was ever going to update 123D Design for Desktop, a brand new 1.4 update comes out and surprises us. The details from their history update from their website looks very promising.
- A new UI introduces similar look and feel with other products from the 123D family, like Tinkercad.
- Easier access to all of your models and projects, regardless of the app you made them in. MyProjects provides access to models created in 123D Catch, 123D Make and 123D Creature.
- Support for opening, inserting, and saving meshes in STL and OBJ formats.
- Perform Combine, Subtract and Intersect operations between meshes and solids.
- New option for combining objects on STL export in order to support printers that read first body only.
- Import SVG files and use them as sketches or as simple extrusions.
- Drop selected objects to the grid with a simple key (F10).
- Added option for hiding grid.
- New toggle for enabling or disabling implicit grouping when snapping between parts.
- New option for defining snapping increments for different operations.
- 3D Print now sends model to Meshmixer for processing before 3D printing.
- Premium members can now download unlimited models from 123D Content Library.
- Free members can now download up to 10 models a month.
- A brand new car! (Just kidding)
- Stability fixes on Copy-Paste.
- Performance and stability bug fixes.
- Support for 3dconnexion devices.
- Shortcut Keys on F1.
- Feedback Survey directly in app under Help.
- Also includes updates for 123D Premium members, and bug fixes.
We think this is a really big update. Our first impressions with the UI redesign are really good. Things did not move around, it’s mostly a graphical refresh, which looks very sharp and clean.
Objects have a nice lime green outline when its selected, making it more distinct. Features that might get overlooked that seem minor are actually handy in use. Hover over the bottom right to quickly change snapping increments and measuring units. Toggling on/off groups when snapping is a time saver and turning the grid off allows you to project sketches from irregular surfaces.
The biggest feature update is SVG import. This is great for making solids from outline sketches made from a vector drawling app like Adobe Illustrator or Inkscape. In our tests, the feature worked best on simple paths. It did an OK job at importing our Adafruit font, but crapped out on our icon. Importing SVG option is available in either a Sketch or Solid. Doesn’t seem like there’s an option (yet) to set the height of an extruded object when importing as an object. You can’t apply construct operations to extruded SVGs which is a bummer but expected from a new feature.
Importing STL is also very welcomed feature that we feel was probably the most requested feature. Tinkercad did this really well and now 123D Design can too. It also gives you a ability to apply basic combine operations like merge, subtract and intersect to solids and other meshes. The best uses of this feature could be for anyone who is looking to make remixes/fixes/customizations/upgrades to STL models like scanned data. You also can’t apply construct operations to imported meshes.
Overall it’s a great update and we really recommend upgrading if you’re already a user. If you’re thinking about learning some CAD for 3D Printing, now is a great time! Special thanks goes out to 123D Design team from Autodesk for making kick ass free CAD software!
