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.
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)
If you use a feed-reader (so 2000), i.e. rss reader, you can find the whole-class feed as http://unrvl.net/wprss .
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 boingboing.net (which they got… Continue reading Coercion-Resistant Design
We often want "muscles" in our projects. But, servos (and motors) are large, power hungry, noisy, and rotate (rather than pull directly). Pneumatics seem to require a bulky, power hungry, noisy pump. Memory metal has some nice scale, but is also power hungry (and hot). Piezo (film) seems promising, but is weak and requires high-voltage… Continue reading Muscles
