@DJDevon3 11:13
* @hopkapi for helping me get past a lot of errors in setting up MYSYS2 and TIO for windows VScode.
* @anecdata for showing me the error of my ways with socketpool and a great way to remember it in Highlander voice: "There can be only one pool"
* @Neradoc for always correcting me whenever I say anything wrong. He's been my mentor for a while even if he doesn't realize it.
* @mac_gyver the developer of TIO for personally coming into discord and working on package errors, feature updates, and submitting a PR to MYSYS2 so the default TIO install in MYSYS2 isn't a 4 year old version. Hopefully we'll see an update for MYSYS2 get pushed out due to his efforts which should make things a little easier for TIO users on Windows.
* @Kattni for working on the lora mailbox project. I see how deep she's had to go. Just want to send her encouragement and looking forward to using her upcoming learn guide for my own mailbox project.
* @Gamblor for sending me a show & tell badge. I've honestly always wanted one and giddy with joy. It's like a newbie badge of honor and I will display it with pride.
* @CGrover & @FoamyGuy for initiating a community wide bug hunt during Community Help Desk on Saturday morning. I learned a lot about bug hunting, it was extremely helpful!
* @Paul Cutler & @TammyMakes for hosting an awesome Saturday session of Community Help Desk. Totally worth waking up for coffee and a chat on a Saturday!
* @everyone at Adafruit for helping to turn dreams into reality every day

@makermelissa
* Group hug
@mark(gamblor) [lurking]16:01
* TammyMakesThings, KeithTheEE, Foamyguy, Paul Cutler and everyone who was at the Community Help Desk.
* CGrover and Foamyguy for poking about the Display Shapes/PyPortal Titano issue on Saturday which turned out to be a stranger but larger performance issue then any of us thought at first.
@tammymakesthings 16:28
* @Paul Cutler, @KeithTheEE, @Foamyguy, and everyone who joined the first Community Help Desk! Also @Paul Cutler for stepping in to record (at least part of) the event when my computer suddenly refused to see any valid audio capture devices in OBS. (I think this is a problem with the macOS beta, unfortunately.)
* @Foamyguy for doing some amazing troubleshooting on the Display Shapes/PyPortal Titano performance issue.
* Group hug to the community for being awesome!
@tekktrik (text only)
* @tammymakesthings for hosting the Community Help Desk this past weekend, sad I couldn’t make it but excited to help with the next one!
* @cedargrovestudios for the new library in the Community Bundle!
* @duckythescientist and @foamyguy for fixing the dotted notation for the RTTTL library - I have a dependent project where I noticed the bug but never confirmed it, so I’m glad that my songs will finally play correctly!
* Group hug!
## 17:43 Status Updates
@Paul Cutler (Hosting) 18:11
* Last week
* Interviewed Bradan Lane for The CircuitPython Show (he’s got some great CircuitPython products!)
* Todbot and I are creating a new podcast! The Bootloader will debut two weeks from today and each episode Tod and I will share 3 things we found interesting. Should be fun. We released a teaser trailer last week. It will air every other week (when my other show is off)
* Working on a 32x8 neopixel matrix and trying to make it sound reactive with a QT PY 2040 and PDM Stemma QT mic. Getting close.
* This week
* Recording the first episode of The Bootloader with todbot
* Ordered some new audio equipment for the podcast and anxiously awaiting it.
* Will miss next Monday’s meeting
@2231puppy (text only)18:52
* Last week
* Finished assembling my E-Fidget PCB and ran CircuitPython on it!
* This week
* Work out the assorted hardware and software bugs in the E-Fidget
@CGrover (text only)19:06
* Submitted two new Community Bundle libraries, PaletteFader (merged) and DRV8830 motor controller driver (waiting for review).
* Now that I’m having relatively good success navigating cookiecutter and pre-commit, there are plans to submit more Community Bundle libraries, starting with RangeSlicer, a map-range-like class that incorporates input hysteresis to reduce noise without filtering delays. Works nicely as a Eurorack CV quantizer but can be applied to other tasks like sensor and potentiometer noise reduction. I used it on a few projects to simulate rotary selection switches with potentiometers.
* Reduced the size of the lawn by 50% to cut water consumption and waste. Trying to be proactive; we don’t have water issues in our area yet. It was suggested that I was just bored with the weekly mowing tasks.
@danh 20:00
* Figuring out the best way to control pins to reduce power consumption during deep sleep.
* Fixing old bugs and new regressions for 8.0.0.
@DJDevon3
* Last week
* Ironed out bugs in my Flock Box weatherstation project.
* This week
* Lost power this week twice due to lightning storms and the battery backup didn't skip a beat. No crashing due to no wifi or disconnect from OpenWeatherMaps, works flawlessly now.
* Designed a 16 step switch sequencer bell for the Pi Pico based on Todbot's Pico Step Sequencer. Took his board schematics from github and in a flurry of excitement hammered out a board design in 2 redbull infused nights. Sent the board off to fab and should be getting 5 prototype PCB's in about 2 weeks.
* Started on an RFM mailbox project that quickly turned into an encrypted RFM messenger app instead. Already have a proof of concept working with fake chat streams going back and forth. This is a big undertaking so I'll be back with updates for a while.
@foamyguy 23:02
* Last week
* Cookie-cut a library for FlipClock displayio widget and expanding the examples to sIhow all basic functionalities
* Participated in Help Desk over the weekend
* This week
* Testing and PR reviews for several libraries. Took an interesting dive into RTTTL spec (Ringtone transfer language) for one of them
* Add documentation and cleanup the FlipClock library code. Implement configuration options that allow it to work with smaller spritesheets to support devices with less RAM to store them in.
* Teaching javascript course in the evenings for the next month or so.
@kattni 24:37
* Last week:
* WiFi Mailbox notifier guide. Text content is now in place. Images remain to do.
* Probably other things, but mostly the guide.
* This week:
* Get images for the Mailbox guide, and get it into moderation to be published.
* Don’t know what’s next.
@makermelissa 25:06
* Last Week:
* Finished up writing Web Workflow Code Editor quickstart guide
* Wrote a bug fix for core for folders being able to move into themselves, but it needs a little rework
* Fixed a few bugs I found in the Code Editor I found while writing guide
* Updated the Loading animation with a spinning circular Blinka
* Added Directory Upload functionality to Code Editor
* Improved Dialog Layering a bit
* This Week:
* Working on a code restructure I’ve been wanting to do for a while
* Testing that code restructure
* Working on more features
@mark(gamblor) [lurking] 25:58
* Last week:
* Submitted a PR for the display shapes/PyPortal issue. There is still a brightness setting issue but the slowdown is now gone.
@TammyMakesThings 26:12
* Last Week
* The first CircuitPython Community Help Desk event! It went really well and there was lots of positive feedback, and some great conversation both in the voice chat and text.
* Did a bit of hacking on @Neradoc’s `discotool` tool to make it automatically run a `discotool cleanup --all` on macOS systems after it runs `circup` commands. (I realized the extended attribute files can take up a TON of space on the device when installing libraries.)
* This Week
* PR Reviews
* Finish looking at my `discotool` tweak, and also investigating whether there’s anything circup can do when downloading the library bundles to avoid creating the macOS extended attribute files in the first place.
* Investigating a workaround for my OBS issue until the new version of macOS comes out of beta
@tekktrik (text only) 27:34
* Last week:
* Created a new library for the Adafruit CircuitPython Bundle - a library for working with location beacons like iBeacons.
* Submitted a fix for adabot’s State of CircuitPython formatting
* Submitted a fix for the cookiecutter adding blank keywords to the pyproject.toml file sometimes
* This week
* Potential PRs for a cookiecutter update and adabot patch for instructions on installing optional dependencies defined in a repo’s optional_requirements.txt
* Add more documentation to the core
* Look at new libraries to create, as well as potentially port to/from Arduino
* Additional typing PR reviews
## In The Weeds 28:22
@tekktrik (text only)
* Are we planning to do Hacktoberfest this year? I loved joining it last year and would love to help set things up if that’s something we’re interested in doing again this year.
* @Paul: Might be interesting to use the next Community Help Desk almost as a sprint? Promote the Help Desk + Octoberfest
* @tekktrik: I’d be willing to host one with this in mind during that time!
* @kattni: We are absolutely doing Hacktoberfest this year, and I would love nothing more than for someone else to help out with things. Adabot automatically applies the Hacktoberfest label to all Good First Issues as it begins, and then we typically see an influx of PRs, so the biggest thing I need help with is keeping track of those PRs, and putting in the work with the authors to get the PRs merged. So basically, keep doing what you already do, but maybe on a bigger scale for a period of time.
* @Melissa - Does Adabot label Blinka libs as well?
* @kattni - Unsure, I’ll look into it.
