Actual Flexible Circuit Seems to be real flexible circuit: transistors made out of flexible stuff. To make stretchable electronic devices, it’s not possible for us to simply swap the silicon with a polymerZhenan Bao of Stanford University The method developed by Bao and her colleagues fabricates 2- μm-wide transistors from semiconducting polymers using ultraviolet light. The first… Continue reading Actual Flexible Circuit

Juanjo Villegas: Plastic Ride

Interested in issues of transportation and recycling? Turning plastic into a scooter. One of the interesting aspects is that this is designed for the user (it can pull a trailer). It's not just an attempt to make a billion dollars.

Docs for CPX (circuit-playground express)

There is documentation for the built-in library ("cpx"). Start with The actual reference is: Programmers will be slightly annoyed, as it doesn't follow conventions we are used to. People, however, will appreciate the pictures, examples, and explanation.

Using Jupyter Notebooks with arduino (CircuitPython)

The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. That means you can program CircuitPython in it! You can also use Jupyter Notebooks for many other programming tasks, including processingJS. In fact, you should go through the "classic notebook"… Continue reading Using Jupyter Notebooks with arduino (CircuitPython)

Coercion-Resistant Design

If you have any interest in resisting power structures (government, corporate), or a radical concern with decentralized systems, or maybe you just think that backdoors lead to general security failure, or as another example of thinking about coercion resistant strategies. So, you might like: Creating a "coercion resistant" communications system from (which they got… Continue reading Coercion-Resistant Design

Yet Another “Printing Buildings”

Every 6 months, someone announces a way to 3D print buildings. Printing the walls is not a solution: they always leave out the utilities. This one is interesting for the undulations. the undulating wall design requires 15% more concrete. but "more efficient at resisting overturning moments" and "reduced the potential for shrinkage cracking near the… Continue reading Yet Another “Printing Buildings”

How do you know the car is paying attention?

Add (animated) googly eyes (via core77) "It's second-nature to glance at the driver of the approaching vehicle before stepping into the road," says Pete Bennett "appearing to 'look' directly at them - signalling to road users that it has identified them, and intends to take avoiding action." Use the natural ways we interact with other… Continue reading How do you know the car is paying attention?

exhibition of algorithmic art

At Boston Cyberarts, an exhibition of algorithmic art till October 28. We often describe the Boston Cyberarts Gallery as an exhibition space for those who regard code as their creative medium. ... all of the artists in this exhibition have developed creative systems for processing information that are simultaneously illuminating and emotive. Should I bother… Continue reading exhibition of algorithmic art

Aka 10KHz, Humans as single pixel cameras

There are single-pixel cameras, that trade time (a series of patterns are projected, and the reflected brightness recorded) for pixels (it's just brightness: single pixel). We can see the original object if the brightness/pattern is played back ... fast enough. Cf. ~16Hz rate of motion pictures ("flicker fusion"). Picture of Einstein in the pdf. Why… Continue reading Aka 10KHz, Humans as single pixel cameras

3D Print Almost Graphene

Seems to be "cured" graphene oxide, but a technique for 3D Printing To create these complex structures, Hensleigh started with graphene oxide, a precursor to graphene, crosslinking the sheets to form a porous hydrogel. Breaking the graphene oxide hydrogel with ultrasound and adding light-sensitive acrylate polymers, Hensleigh could use projection micro-stereolithography

Artificial Mangrove

Math, modeling, water tanks, to figure out how mangrove roots work to resist storms. Via mangrove root systems even have the ability to dissipate tidal energy through unique hydrological flows and divert the energy of water ... robust network of roots that can withstand extreme environmental conditions. modeled the complex mangrove roots as a… Continue reading Artificial Mangrove

Self-folding tiny origami robots

Watch the frenetic behavior. “It’s called a one-degree-of-freedom structure, in which you just need to turn one crank and the whole thing moves in the way that you want,” Demaine explains. “It lets you transfer just one degree of freedom into a whole complicated motion, all through the mechanics of the structure.” This is an… Continue reading Self-folding tiny origami robots

particles + water + pressure

Liquification of bulk cargo can sink ships: granular materials loaded directly into a ship’s hold – can suddenly turn from a solid state into a liquid state... Solid bulk cargoes are typically “two-phase” materials as they contain water between the solid particles. As everyone knows, liquification happens during earthquakes A lot is known about the… Continue reading particles + water + pressure

RFID Circuit Bending

LiveTag (via slashdot) new smart tags that harness reflected Wi-Fi signals ... copper foil printed onto lightweight paper-like material ... had to experiment with many different combinations of shapes, sizes, and materials for the LiveTags and run all those combinations through computer simulations. ... the smart tags only work within a three-foot range of Wi-Fi… Continue reading RFID Circuit Bending

They Make Pretty Stuff, I Guess

Pretty "fab" stuff is in Albuquerque We use complex emergent phenomena to craft bits & atoms into toys & games from an infinite Universe of possibilities. Through the power of custom software, nature inspired algorithms and digital fabrication tools, we transform natural materials into beautiful artifacts of computation. What do they do? You can't tell from… Continue reading They Make Pretty Stuff, I Guess
