https://physics.aps.org/articles/v14/130 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
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. https://s3files.core77.com/blog/images/1207473_34481_109836_GYDSU2v7r.jpeg https://www.core77.com/posts/109836/Circular-Economy-and-Micromobility-This-Electric-Scooter-Adopts-a-Sustainable-Approach-to-Urban-Transportation-Solutions
There is documentation for the built-in library ("cpx"). Start with https://circuitpython.readthedocs.io/projects/circuitplayground/en/latest/index.html The actual reference is: https://circuitpython.readthedocs.io/projects/circuitplayground/en/latest/api.html Programmers will be slightly annoyed, as it doesn't follow conventions we are used to. People, however, will appreciate the pictures, examples, and explanation.
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”
one way to get height into a map Height tells you so much; the steepness of streets, where water tends to flood, even often class distinctions ... a trimetric projection (it’s like isometric) The repetition of the wedges makes the topography visible.
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?
