## 3:21 Community News
### CircuitPython Takes Flight in MS Flight Simulator
Creating a flight controller for Microsoft Flight Simulator using CircuitPython and custom circuits - Hackster.io and Twitter.
For many years, I have used and played in Microsoft Flight Simulator X. In anticipation of the upcoming release of the new version - Microsoft Flight Simulator 2020 - I wanted to ensure I had the best set up ready for flight! I knew that CircuitPython had a gamepad software library that makes your CircuitPython code appear like a Joystick. I had an idea that this could be hacked up (easily) and make to suit my purpose. CircuitPython also makes working with hardware easy.
### CircuitPython CLUE Cutebot
CircuitPython-CLUE-Cutebot is a higher-level library to allow Adafruit's CLUE and ElecFreak's micro:bit Smart Cutebot to communicate while maintaining all the functionality of the CLUE, except for touch features - GitHub and YouTube.
I am a teacher of young learns and as such the code was purposefully left simple so I can use it with them. There is also a comment on nearly every line to help explain to my students what each line is doing.
### CircuitPython Day is 9-9-2020
Adafruit has chosen September 9, 2020 (9/9/2020) as the snakiest day of this year for CircuitPython Day! Much more to come on events and happenings to include a CircuitPython team livestream, collaboration with hardware and software folks, and highlighting all things Python and Python on Hardware.
It was with great sadness that the community saw the devastation of Beirut several days ago. So many residences were heavily damaged. It was a great relief to hear from our 2019 CircuitPython Day partners Lamba Labs Makerspace:
Things have been quite tough these days, but so far all manageable. We did a roll call yesterday on all our maker communities. Aside from minor injuries and stitches, broken glass, broken window frames (aluminium and wood), and some broken cars, no real harm done. All the love from here in Beirut heart
Adafruit is dedicating CircuitPython Day 2020 to Labma Labs and supporting NGO fundraising for the city:
– Impact Lebanon fundraiser: their focus is rebuilding lost homes, houses, historic landmarks, and affected hospitals.
– Anera and Global Shapers fundraiser: an NGO which is coordinating with 12 NGOs including Red Cross Lebanon division and Caritas. Their main goal is collecting funds to sustain the affected families until they can financially recover from the explosion.
More information on CircuitPython Day is forthcoming. Ideas? Send them via email to circuitpythonday@adafruit.com.
### Even more stuff
Simulating firefly flashes with NeoPixel LEDs in CircuitPython - GitHub.
CircuitPython_CLUE_Menu - make your Adafruit CLUE multi-functional by adding a nifty startup menu to select the program you want to run. You no longer need to rename your files to code or main to run them. Simply drag and drop your files into your CIRCUITPY drive and this menu program does the rest - GitHub and YouTube.
Conway's Game of Life on an ESP32 with MicroPython and an LCD display - Twitter, YouTube and GitHub.
Python Tea #10: Special Guest Łukasz Langa on release management, typing in Python, asyncio, MIDI, Synths - Twitch.
Ocean Epoxy Resin Lightbox with RGB LED Matrix Image Scroller from Erin St. Blaine
### Contribute to the newsletter
The CircuitPython Weekly Newsletter is a CircuitPython community-run newsletter emailed every Tuesday. The complete archives are here. It highlights the latest CircuitPython related news from around the web including Python and MicroPython developments. To contribute, edit next week's draft on GitHub and submit a pull request with the changes. You may also tag your information on Twitter with #CircuitPython.
## 7:00 State of CircuitPython, Libraries and Blinka
### Overall
* 22 pull requests merged
* 15 authors - Gadgetoid, wtuemura, jepler, xiongyihui, FoamyGuy, siddacious, weblate, nvtkaszpir, makermelissa, rhooper, ciscorn, kmatch98, linusg, dglaude, sommersoft
* 8 reviewers - jepler, kattni, ladyada, caternuson, tannewt, makermelissa, rhooper, dhalbert
* 27 closed issues by 16 people, 12 opened by 9 people
Overall: We continue to have strong contributions to Core and Libraries. Aside from the new libraries in the Adafruit bundle, I also want to highlight a new library in the Community bundle for the LTR-559 light and proximity sensor found on the Pimoroni Enviro Plus Featherwing.
Carried over from last week, we need to make a new alpha release of the core soon. There are currently 269 commits in 23 pull requests that are on our main branch but not released yet, so we need to make it easier for the community to access these features and bug fixes.
In the core we also have a new Japanese translation by @ciscorn. Thank you! That makes the 15th language besides English that we’ve added.

* EnviroPlus FeatherWing
* Tested saving memory on Pimoroni_CircuitPython_LTR559 by moving constant to a separate file.
* Transformed Adafruit_CircuitPython_PM25 library into a package, waiting for PR review (and someone to test the I2C version because I only have the UART hardware).
* Transformed Adafruit_CircuitPython_IS31FL3731 into a package, waiting for PR review (I don’t have all the hardware to test).
* Connected a CLUE on a Pi with "the CZH-Labs Micro:bit X Raspberry Pi Interconnection HAT, Microbit to RPi Adapter Board" I have accessed the 5 I2C sensor. Now investigating the screen/SPI and other hardware: button, LED, RGB LED.

* Try to finish resolving the display_text position issue
* Test and review a PR for the PN532
* Keep working on Display Layout library. Perhaps implementing the Grid Layout. And then “kicking the tires” by trying to use the module to refactor a few existing UI heavy projects with to see if I run into issues and see how the code turns out once the UI stuff can be more separated from the rest of the logic.
* Fun / Outside Circuit Python:
* Factorio 1.0 was released over the weekend! I spent some time playing the release version to celebrate. And am planning to mash these interests together by creating a Circuit Python based hardware “Rocket Launcher” button.
