Build an amazing LED display using Sparkle Motion and a 16x16 NeoPixel matrix. Use WLED software to play awesome animations that are designed for 2D matrices. A 3D printed frame and piece of black LED acrylic create an assembled display that can sit upright or mounted to a wall.

This week, we were all over the place with a bunch of different designs and experiments. After last week’s analysis of the TLV320DAC3100, we made some updates to the design and re-booked prototype PCBs.
We also designed a triple-matrix bonnet: with our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5, we can now do matrix control on the latest Pi 5 chip. But we’re limited by the RP1 chip, so to get big displays going, we’ll need multiple strands—these don’t use significantly more bandwidth because half of the pins are shared.
Finally, we ended the week by getting another older prototype working: the SAM-M8Q is an entry-level all-in-one GPS from u-blox. It comes with both UART and I2C interfaces, plus a built-in antenna, so it’s ready to go out of the box. The NMEA interface is trivial, but we also wanted to try out the UBX interface, and thankfully, Claude 3.7 was able to vibe-code it for us in a jiffy.
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.
