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

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

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

DIY Metamaterials from Origami

In the paper Origami - inspired Cellular Metamaterial with Anisotropic Multistability we create a family of origami-inspired cellular metamaterials which can be programmed to have various stability characteristics and mechanical responses in three independent orthogonal directions. ... Our study provides a platform to design programmable three-dimensional metamaterials significantly broadening the application envelope of origami. Metamaterials… Continue reading DIY Metamaterials from Origami

Its Own Sensor: Side Effects

Via boingboing: The very clever Electron Plumber figured all this out and built an LED "candle" that goes out when you blow on it, using the LED itself as a sensor that detects voltage drops (caused by cool air, caused by blowing) Realizing a side effect can be exploited is cool. In various incarnations of… Continue reading Its Own Sensor: Side Effects

Chibitronics: The Lego of Electronics?

Chibitronics makes circuit stickers and other tools for paper circuits, which blends circuit building and programming with arts and crafts.  It’s a friendly way to learn, design and create your own electronics. Looks at least like a good way to explore making a circuit, and learn some basics. Is it good for making a real… Continue reading Chibitronics: The Lego of Electronics?
