I scream, you scream, we all scream for Python
When Edvard Munch painted his most famous painting, The Scream, in 1893 he perfectly captured the existential angst of modern humanity. He did not, however, have access to a microcontroller board with built-in sound sensing, connected to a servo motor and speaker, so he failed to make his masterpiece interactive.
Using the Crickit with Circuit Playground Express, and a bit of code in CircuitPython, we can make The Scream scream back at you when you scream at it! – learn.adafruit.com & video.

This is follow up from a previous newsletter item, the code is up. e-Paper Display driver code for Circuitpython with a fractal demo, it draws a Julia or Mandlebrot fractal on the display. This code was written and tested on an Adafruit Metro M4 running Circuitpython 3.0. The e-Paper displays are the monochrome SPI varieties from Waveshare. Six digital I/O pins are required – GitHub.
The EuroPython Conference videos from last week have been posted – YouTube.
Post Mu 1.0.0 release, Hacker News picked it up and the lead developer ntoll answered some questions in the comments, if you’re interested on how some of Mu works, motivations, and more, check it out – Hacker News. Looks like a tag line for Mu has arrived from the comments – “Python is a language that helps make code readable, Mu is an editor to help make code writable.”
Speaking of Mu (and EuroPython!) Mu was used in the opening conference keynote by Pythonista-extraordinaire David Beazley. Here’s why – “From a more practical point of view, I choose to use Mu for my talk precisely because it was extremely simple. I do a lot of live-coding in talks and for that, I usually try to keep the environment minimal. […] Part of the appeal of Mu is that I could code and use the REPL without cluttering the screen with any other unnecessary cruft. For example, I could use it without having to switch between terminal windows and I could show code and its output at the same time in a fairly easy way.” – MadeWith.mu & video.
