This week at the desk, we worked on getting more small hardware boards done.
We revised our 1.5” transparent OLED breakout (oops, pins were swapped), designed breakouts for sensors like the AS5600 (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/AS5600-ASOM/8250257) and STHS34PF80 (https://www.digikey.com/en/products/detail/stmicroelectronics/STHS34PF80/13187390), and updated the NAU7802 (https://www.digikey.com/en/products/detail/nuvoton-technology-corporation-of-america/NAU7802SGI/4929384) to have both ADC ports available.
We’re also working on another stepper motor driver, since the TMC2209 breakout (https://www.adafruit.com/product/6121) was a big hit.
We wrapped and sent out the Triple-output Active Shifting RGB Matrix Bonnet (https://blog.adafruit.com/2025/02/28/triple-matrix-bonnet-makes-big-bright-displays/).
Then we finally had a little time to get back into bigger projects, like Fruit Jam, which we re-picked-up! This week we focused on implementing the ESP32-C6 Wi-Fi co-processor, which needed a bit of rework, but now we’ve got rev C prototype PCBs on the way.

You can build a 3D printed IoT alarm clock using CircuitPython and electronics from Adafruit.
Guide: https://learn.adafruit.com/led-matrix-alarm-clock
This LED matrix alarm clock is inspired by the cute plush toy monsters LaBuBu by Pop Mart.
It gets time from the internet and features sound effects, brightness dimming for night time and cute animations like winking eyes.
The clock is powered by an Adafruit QT Py ESP32-S3 with an amplifier for high quality audio output.
Set your timezone, alarm time, volume, and the LED brightness settings for day and night. The alarm sounds are audio .mp3 files that are randomized each time they’re triggered.
Scrolling text is displayed when an alarm goes off, and a winking eyes animation plays – giving the clock some character.
A rotary encoder is used to set the alarms. You just press on the encoder and turn the knob to set hours and minutes. Text will display to show if the alarm is On or Off.

You can build a tap-to-play video player using a Raspberry Pi 5, Adafruit’s NFC Breakout and NFC cards. Full Tutorial: https://learn.adafruit.com/nfc-raspberry-pi-media-player
To play a movie, just tap an NFC card over the 3D printed case. A python script runs code that launches movies in the VLC media player.
The NFC cards are fitted inside a 3D printed case inspired by VHS cassette tapes.
This project aims to make the movie watching experience more special by creating a physical experience. No streaming networks or wifi necessary!

Full tutorial: https://learn.adafruit.com/chinese-dragon-puppet-with-motion-reactive-flame-effect/overview
Make a Chinese Dragon puppet with a dramatic flame LED effect. The lights are motion-reactive so he lights up when you shake him. This project uses an Adafruit Circuit Playground Express with a built-in motion sensor and NeoPixel LED lights. The code is written in Microsoft MakeCode, an easy-to-use drag and drop code editor. (Or maybe in this case, a dragon-drop code editor.)
This is an easy beginner-level project that involves a little bit of soldering. You can download our code sample, or learn to make your own flame effects. This is a fantastic project to do with kids.
