Another weird day of DIY between meetings and frontend prototypes at work.

If a colleague asks you if they can build a DIY keyboard-shortcut-button-box-for-powerpoint-ui-papercuts, you should always agree to do it. The large 30 mm arcade buttons are a great touch.

The Adafruit Kee Boar is a super fun board. I'd argue #circuitPython is a little too easy. I was able to get the button input as HID device with the documentation in minutes.

I was on the #teachingpython podcast! I got to talk with Kelly and Julian about Python, #CircuitPython, UF2 bootloader troubles, and #embedded systems in general. It was a lot of fun. https://www.teachingpython.fm/156

When Code Leaves the Screen

In this episode of Teaching Python, Kelly Schuster-Paredes and Julian Sequeira talk with engineer and maker Todd Kurt about physical computing and what happens when code moves from the screen to hardware. The conversation focuses on CircuitPython and MicroPython, including how they differ in design, teaching focus, and tradeoffs. Todd describes his background in engineering, web development, and open source hardware, and the group discusses practical classroom challenges such as bootloaders, UF2 files, board compatibility, libraries, and wiring mistakes. Kelly and Julian also share examples from their classrooms, where students use boards, sensors, NeoPixels, and other devices to build tangible projects and develop troubleshooting skills.

This was so kind. An exchange student who took both my #CircuitPython & my #SwiftUI apps courses made this for me. The flowers are 3D printed & the vase was laser cut. Lovely.

How to Re-initialize a Stuck #ESP32 (in #CircuitPython) -- something I needed when working on my particulate air quality #sensor but I'm sure I'll need it for many other projects:

How to Re-initialize a Stuck ESP32 (in CircuitPython) (Shallow Thoughts)

Whatisgoingon Apr 29

I am trying to get this TEA 5767 to work. This ESP32S3 does not have a onboard I2C so I read that I have to use 4.7kOhm resistors to create a pull-up.

The device is connected to 3.3v and the pins SCL,SDA are connected to 3.3V and the pins 4 and 5 on the board.

I use busio.I2C and can get a connection and lock on the I2C.

i2c.scan() does not find the 0x60 address but sometimes I get "'0x8', '0x9', '0xa', '0xb'"

[SOLVED]

The top feature project on Autodesk Instructables today is by my Physical Computing students Noah Priest & Vinith Ayapilla! An accessible driving game they created for children with disabilities in the Campus School at Boston College. Built in #CircuitPython. Students present their accessible tech work today. Congrats Nick & Vin!
