In this tutorial, we’ll show you how to make your very own Neopixel Novelty Cufflinks using Adafruit’s QT Py RP2040 and a NeoPixel 5×5 BFF add-on. This project is easy enough for beginners with just a little soldering and a little wire management. We’ve also added a metal bezel on the front filled with UV Artist resin so you can customize your diffusion.
The tutorial includes detailed instructions and all the code you need to get started. From the guide:
Complete your look this Valentine’s day with NeoPixel novelty cufflinks. Add your own scrolling text messages to send a surprise smile to that special someone’s face. Whether it’s a romantic declaration of love, a sweet message of affection, or simply a playful joke, the customizable scrolling text will get your point across in a fun and silly way.
This is a fairly easy project. There’s a little tight soldering work, but there are only 3 pieces to assemble so you can do this project in an afternoon, and finish it in time to impress your sweetie with your mad maker skills.
This project would also make a wonderful hat pin, brooch or necklace with just a little modification. It packs a punch with 25 pixels in a teeny tiny package.
