Mini BSG Colonial Viper Mk II Popsicle Stick Model
Only nine (9) major sub-assemblies (including the two tiny rear landing gear housing!) makes up this mini Battlestar Galactica Colonial Viper Mk II. This should should be an easy build even for novice hobbyists.
The Viper Mk II was the main fighter spacecraft used by the Colonial Defense Forces against the Cylons in the 2003 remake of Battlestar Galactica. A Mk I from the 1978 series should also make for an interesting one-day build.
The only major challenge in this project was in fabricating the top engine and engine exhaust nozzle. The engine exhaust nozzle should fit snuggly inside the shaped housing at the rear end of the top engine.

Build a Paper Robobee Model
Have you ever seen miniature flying robotic insects in movies? That might sound like something completely out of science fiction, but believe it or not, engineers at the Harvard Microrobotics Lab are actually working on a bug-sized flying robot called the "RoboBee": While this Instructable won't actually tell you how to build the real thing (which still requires a lot of expensive laboratory equipment), it will show you how to make a paper model of a RoboBee. This is something engineers in the lab do all the time - real RoboBees are pretty tiny, so having a larger paper model helps them think about mechanical design and how all the pieces will fit together.
The secret to making RoboBees involves using lasers to cut shapes out of flat materials, and then folding or "popping up" these flat shapes into three-dimensional structures. The following video by Pratheev Sreetharan provides a great introduction to the "pop-up" technique for building RoboBees. In this project, you'll be cutting out 2D parts and them folding them into 3D shapes by hand, so it won't be quite as automated as the process shown the video.
Materials
8.5"x11" sheet of cardstock. You need at least one, but can use different multi-colored sheets if you want. Regular construction paper will be too flimsy. Craft glue (regular Elmer's glue will work fine) There are three options for cutting out the parts: Option 1: Xacto knife, cutting mat, and a steady hand Option 2: Electronic cutting tool (I used a Silhouette CAMEO) Option 3: Laser cutter, if you have access to one. Be sure to follow all proper safety procedures and do not use a laser cutter if you are not trained on its use - they can start fires or generate toxic fumes. Design file: available for download below as a .pdf or on Thingiverse as a .studio (proprietary format for the Silhouette CAMEO - Instructables wouldn't let me upload it). If I get enough requests I will redo the drawing as a .dxf or .dwg - so far I haven't been able to export these formats from Silhouette Studio (feature request in case anyone from Silhouette is reading this!). Optional: 2D CAD program, if you want to try out your own designs and are using an electronic cutting tool or laser cutter. There are multiple free options out there - I've used DraftSight (which was free last time I checked) and I believe you can also download a free student version of AutoCAD (may require creating an account). I know Autodesk has a bunch of new 123D apps, but I'm not sure if any of them are exclusively 2D programs that will output a dxf or dwg that you can use with a laser cutter.Credits: These directions were written while I was a postdoctoral researcher in the Cornell Creative Machines Lab. The RoboBee project was started at the Harvard Microrobotics Lab. For more information and technical details about the project, you can check out the lab's publication page or YouTube channel. You can also check my personal publications page, which includes my Ph.D. thesis on body torque actuation. To see some more awesome engineering work on functional robots made out of laser-cut paper, check out the Berkeley Biomimetic Millisystems Lab.
Before you start building a paper model, you're probably wondering how exactly a RoboBee works. Here is a really quick, layman's-terms explanation of the four main parts, which are labeled in the picture above. Airframe: this is the robot's "body". It's the rough equivalent of an insect's exoskeleton. Nothing super high-tech here - it's pretty much just a box made out of carbon fiber that holds all the other pieces together. Actuator: actuator is the engineering term for "thing that causes motion". In machines, actuators are usually motors or engines. In animals, actuators are muscles. In this case, the RoboBee is actually way too tiny for a motor - so we use a piezoelectric material, which deforms when an electrical voltage is applied to it. A piezoelectric beam bends back and forth as this voltage changes, acting like a "flight muscle". Transmission: this is another engineering term. The transmission converts the back-and-forth motion of the tip of the actuator (which is roughly moving in a straight line) to the rotational motion of the wings. It's hard to see in the picture here - this will make more sense when you build your paper model. For now, think of it like a linkage built out of LEGOs or K'Nex, if you've ever played with those. Wings: This is the most self-explanatory part. The wings flap back and forth to generate lift, which is what makes the RoboBee fly. More advanced versions of the RoboBee have multiple actuators to independently control the wings, which allows them to steer. Thursday, August 1, 2013
How to tie a 320 facet globe knot using a 3D printed model
A globe knot is a form of Turk's head knot that can be tied to cover a sphere. The standard way to tie a globe knot is to tie the knot around a cylindrical mandrel, then transfer the knot to a ball that you want to cover. In this instructable I'll show you how to tie a 320 facet globe knot by 3D printing a model of one and directly tying the knot around it. For great instructions on how to tie many different globe knots using a mandrel I recommend The Globe Knot Cookbook, by Don Burrhus: http://knottool.com/gk_kit.html
The model of the globe knot can be ordered from my Shapeways shop: http://shpws.me/nuZnI recommend getting it in the white, strong and flexible material as we'll be sticking pins in it. When I received mine, there was a lot of white powder still in the middle, so I recommend rinsing it in water to get it out. Then let it dry before you begin tying.
Or, if you have a 3D printer you can print the attached stl file.
You'll also want some T-pins and some kind of small diameter cord. I'll be using lacrosse crosslace which can be ordered online in many different colors: http://bit.ly/15vKcXg

DIY Polaroid Swinger Model 20 To Canon EF DSLR Lens
A Polaroid Land Camera Swinger Model 20
A good brand epoxy glue
A set of Canon EF Macro Extension Rings. I just got some cheap ones. Mine has 7,14 and 28mm. written on them. Others has numbers 1,2,3 on them. Get the 7,14 and 28mm. ones if you can. I don't know if the others are the same size. You should get this with the AF-Confirm chip installed.
Some Canon EF Macro Bellows. Again I got the the cheap stuff. You should get this with the AF-Confirm chip installed.
A Phillips head Screwdriver
A Compass. This is for drawing circles, not for finding the North Pole
A Ruler and a Vernier Caliper.
A flat black piece of plastic sheet 5x5 cm. You can get this from smashing the remains of the camera body.
A flat black permanent marker. I used a Posca marker.
Some paper.
Scissors
Note: AF-Confirm is when your normal AF lenses, confirms that you have reached focus. This is pretty handy, so get your adaptors with it.
