Thermoextensible 3D Printed Structures: Capabilities and Applications

General Guidelines and Properties: To maximize extensibility, unit cells and tessellation patterns should be selected to minimize the number of minimally-connected vertices in a unit cell. These factors can be varied directionally to create anisotropic properties, as in the unidirectional example above. Rectilinear tessellation of square unit cells engages all members in tension when thermoformed and most deformation is derived from angular deformation around vertices and linear extension of constituent members.

Hexagonal tessellation of regular hexagons deforms slightly more due to the higher stresses in constituent members as a result of the lower edge-to-vertex ratio. Home — Precious Plastic. Course on MIT App Inventor and Arduino. I have made many tutorials for creating apps using MIT app inventor and connected the app with arduino to make things work, I often get email stating something went missing when they follow my tutorial, Here's a step by step tutorial on getting started with creating MIT app inventor and control things with arduino.

How to Reuse Washing Machine Motors - (The Simple Way ) Harvard releases its DIY soft robotics toolkit. Harvard, arguably the most famous Ivy League university on Earth, has a long history of democratization of education; together with MIT and several other elite institutions, they’ve pushed hard to make online learning easy and high in quality.

However, one aspect of learning that’s intrinsically difficult to export from the physical school is the physical lab experiment; universities often invest tens or hundreds of thousands in equipment that makes it possible to apply many of the engineering principles explained in digital textbooks. Hacking households presents open system for appliances at BIO 50. Sep 30, 2014 hacking households presents open system for everyday objects at BIO 50 hacking households presents open system for everyday objects at BIO 50photo by tilen sepič open source thinking has been permeating into all areas of design in recent years, through increased access to technologies such as 3D printing and do-it-yourself circuitry, as well as a general criticality towards industrial processes which have dominated the past century. to build upon this forward thinking and optimistic dialogue, a team was assembled for BIO 50 – ljubljana’s biennale – to rethink the basic structure through which everyday objects are conceived, made, and used. built upon a simple framework, ‘hacking households’ allows for a high level of variability and customizationvideo courtesy of tilen sepič the basic three-blade fan compositionphoto by tilen sepič the hand mixerphoto by tilen sepič.

Iron Man helmet with servo hinges. Yessss. Other IM helmet. Sorry. CNC. Price quotes. 3D Printed Optics. 3D Printed Optics I came across a rather interesting idea while checking out Disney's Research Hub: Printed Optics.

3D Printed Optics

They seem to be quite interested in fabrication and 3D printing as a good majority of their videos pertain to this type of subject matter. More interestingly, they have devised a way to print objects that embed optical characteristics so that light traverses where they intend to create some very interesting effects. The idea is to fabricate using 3D printing technology, I believe they are using resin based. The machine's head and platform is shown while the process of printing the object was demonstrated in fast motion and appears similar to the objet printer.

Generally, the resin that is used for stereolithography machines can be obtained optically clear, but the models would need to be built up using various resins, differing in color and opacity to be really rich in appearance and function. You can see that the video below also uses this technique:

UNANYTHING. Robots That Create Art: Harvey Moon's Drawing Machines. How does a cricket become an artist?

Robots That Create Art: Harvey Moon's Drawing Machines

Try placing it in one of Harvey Moon's drawing machines where its movements will be tracked by a camera and turned into original works of art. Bugs Draw For Me, just one of Moons' impressive setups, are "happy collaborations" built in his Chicago studio where he creates the system, a set of rules, and allows a machine to do the rest.

The machines are created from motors and servos, while the drawings they create are defined by algorithms which determine the machine's movements and gestures. For Moon the art isn't necessarily the drawing that the machine produces, but rather the performance of the machine in the act of drawing. Part of that process is how, often, a machine can fail at what it was told to do.

How to Turn Your House Lights On & Off Using the Internet

I think that homes are headed towards an era where they will be controlled by our computers and smartphones. No longer will you have to find your keys to unlock your door, or wait until you get home to monitor your security, because X10 is here. X10 allows powerline modules to communicate via the existing 120v AC wiring in your home.

Simply plug or wire in an X10 compatible module into your AC supply and it can communicate with any other X10 device in your home, giving you remote control of virtually any light, appliance, or other contraptions that you may have invented. X10 has been around since the '70s, so it is a tried and true tested technology. Today, Null Byte is going to take a hack at controlling our home lights via our computers with the X10 kit.
