### 4:50 Adafruit IO Wippersnapper - We're looking for beta testers!
Adafruit is starting to expand the beta program for Adafruit.io WipperSnapper. If you don't know already - Adafruit.io WipperSnapper is a no-code IoT interface for Adafruit.IO – it lets you turn any WiFi-capable board into an IoT device without any programming. Simply select what devices are connected to which pins on the hardware and it will auto-configure the firmware and even create an IO feed for visualization. The service is 100% free, all you need is an Adafruit.com account.
For information about how to get invited, see the post on the Adafruit Blog.
### 5:35 The CircuitPython GitHub Repo Exceeds 2,500 Stargazers
The CircuitPython GitHub repo exceededs 2,500 Stargazers this week! Thank you to all the people who have chosen to star the CircuitPython code repository - Adafruit Blog.
### 5:55 Hack Chat with Adafruit's Ladyada July 21st
The Adafruit crew will host the Hack Chat on Wednesday, July 21 at noon Pacific / 3pm EDT.
Especially over the last year and a half, most of us have gotten the feeling that there's little distinction between our computers and ourselves. We seem welded together, inseparable even, attached as we are day and night to our machines as work life and home life blend into one gray, featureless landscape where time passes unmarked except by the accumulation of food wrappers and drink cans around our work areas. Or maybe it just seems that way.
Regardless, there actually is a fine line between machine and operator, and in most instances it's that electromechanical accessory that we all love to hate: the keyboard. If you buy off the shelf, it's never quite right -- too clicky, not clicky enough, wrong spacing, bad ergonomics, or just plain ugly design. The only real way around these limitations is to join the DIY keyboard crowd and roll your own, specifically customized to your fingers and your needs -- at least until you realize that it's not quite perfect, and need to modify it again.
Hitting this moving target is often as much a software problem as it is a hardware issue, but as is increasingly the case these days, Python is ready to help. To go into depth on how Python can be leveraged for the custom keyboard builder, our good friends at Adafruit, including Limor "Ladyada" Fried, Phillip Torrone, Dan Halbert, Kattni Rembor, and Scott Shawcroft will stop by the Hack Chat. We suspect they'll have some cool stuff to show off, in addition to sharing their tips and tricks for making DIY keyboards just right. If you're building custom keebs, or even if you're just "keyboard curious", you won't want to miss this one - Hackaday and YouTube.
### 7:44 New Book: Visual Studio Code for Python Programmers
A new book, just out, is a huge boon to Python developers looking to use the free Visual Studio Code (VSC) editor, aptly named: Visual Studio Code for Python Programmers, by April Speight - Adafruit Blog with review and Amazon.
### 8:11 Projects Using the New GitHub Copilot AI Knowledgebase
Users continue to test the technical preview of GitHub Copilot to see what it can do. Here are a couple of examples of note:
* Copilot writes a text-based game in Python - sandyuraz.com.
* Copilot Importer: why write code when you can import it directly from GitHub Copilot? - PyPI.org.
### 8:50 30,000 thanks for the Adafruit Discord Community!
The Adafruit Discord community, where we do all our CircuitPython development in the open, reached over 30,000 humans, thank you! Adafruit believes Discord offers a unique way for CircuitPython folks to connect. Join today at https://adafru.it/discord.

## 25:48 Status Updates
26:13 @tannewt
* Merged in micro:bit v2 support. Still kinda rough.
* Switched to knocking out issues for 7.0.0. It’s a nice change of pace.
* Made a PR for all_matches for ScanEntry.match
* Made a PR to remove MICROPY_PORT never reset-ish defines for atmel-samd. It’s much clearer to use never_reset everywhere.
* More issues this week and continuing to push the BLE app side of things. iOS will pick up next month as Antonio has more availability.
27:53 @danh
* Fixed a build issue re uploading stubs.
* Fix some typos in `keypad`.
* Wrote a small library for @kattni to convert keypad events into states.
* Still working on audio issues on RP2040. Narrowing it down.
29:37 @foamyguy
* Last week
* Created a basic math practice problem application for the macropad
* Made some tweaks inside the MacroPad library to make it’s pixels object compatible with the LED_Animation library
* Swept through Learn Guide repo to make some fixes based on new behavior with OnDiskBitmap
* Learned about the cycle_complete callback from LED_Animations and figured out how to use it to run a single cycle of the comet animation.
* This week
* Begin a larger effort to fix things that result from breaking changes with 7.x across many libraries and learn guides.
* Learn more from “under the hood” in LED_Animation and try to create some custom animations that I have in mind.
* Record an updated video about installing and using CircuitPython stubs now that it is much easier to do.
31:43 @hierophect
* Last week:
* Mayhem with moving, family, and job transition stuff
* Resolved a timer leak in the ESP32S2 PWM module, along with a number of other unseen issues, making it an mild refactor overall.
* Rebasing the exception storage PR, which has taken me longer than I’d like to catch up with given all the heap stuff it’s working with.
* Last couple weeks, implementing the SleepMemory modules on STM32, RP2040 and revisiting/double checking ESP32S2 and NRF52 for use with the next file system
* This week:
* Finish the exception storage rebase, and fit it in alongside the low power code so it works with the new next file changes
* Wrap up the sleep memory stuff for Next File
* See how much SAMD deep sleep help I can fit in before starting my new position
35:13 @jepler
* Last week:
* Calculator guide went live last week!
* JPEG mode for OV2640, tested on ESP32-S2. You can save a 2 megapixel jpeg to an SD card, wow! There are problems carrying over the correct exposure value from the preview mode, though.
* Flash savings PRs all got merged (I have some more space savings ideas cooking but won’t PR them yet)
* This week:
* 7.0.0 milestone issues (one PR in for review this morning; I need to grab more from the list because I only got a light load on Friday)
* Working on camera exposure settings carryover
* Maybe adding the adafruit_ticks library
* Participating in the Keyboard Hack Chat on Wednesday -- https://hackaday.io/event/180454-python-your-keyboard-hack-chat-with-adafruit
36:50 @jerryn
* Submitted PR to enable CRC by default for RFM9x
* Minimal impact on exiting CP deployments due to the use of “explicit header”
* Header overrides the CRC setting anyway. Radiohead has an additional check.
* Tried to test microbit-v2 but could not get it working via Mac/Chrome
39:12 @kattni
* Last week:
* Updated MacroPad guide to not have warnings about using “Absolute newest” CircuitPython after 7.0-alpha.4 was released.
* Replaced code elements with embedded code from GitHub (there was an issue with CI on the Learn repo that needed to be dealt with, and wasn’t handled until the weekend, so code embeds were updated during the week.)
* Added MacroPad library to the bundle
* Continued updating the MacroPad library to address bugs/feature requests
* Tested a PR on pypixelbuf and merged.
* Tried adding color constants to `rainbowio` per Limor’s request, but determined it’s not worth the bytes for now.
* Published the TCA4307 guide - I2C hot-swappable buffer
* Wrote up a MacroPad HID demo for Noe and Pedro that lights up each key when pressed and plays a different tone for each key pressed.
* Started the NeoKey Ortho Snap guide
* Started a spreadsheet to track the 7.0.0 CircuitPython API breaking changes and current library breaking changes
* Created a new Python library called `adafruit_pixelbuf`, and migrated code from `adafruit_pypixelbuf` minus the `colorwheel()` code.
* Renamed `_pixelbuf` to `adafruit_pixelbuf` and aliased back to `_pixelbuf` for now to maintain backwards compatibility.
* Put in PRs to update NeoPixel and DotStar to use `adafruit_pixelbuf` if available, and if not, fall back to `_pixelbuf` or `adafruit_pypixelbuf` for backwards compatibility.
* Added `rainbowio` to Blinka.
* This week:
* Continue the NeoKey Ortho Snap guide
* Go over breaking changes spreadsheet with @foamyguy
* Look into why the CircuitPlayground library PR is failing Sphinx
* Hackchat Wednesday
* Once `alpha.5` is released, update any code examples using `_pixelbuf.colorwheel()` to use `rainbowio`
45:16 @MakerMelissa
* Last Week:
* Finished up my Cat Detector guide
* Added BeagleV Starlight Beta Prototype support to Blinka
* Fixed an issue with the MagTag’s NeoPixels and CircuitPython 7
* This Week
* Working on GitHub issues I had put off
* Look into a possible SPI issue/fix with Blinka
* Continuing on the WebSerial ESPTool fixes for the ESP32
