My wife sells jewelry at local markets. I wanted to create my own item to sell. Diffused glowing LEDs behind a PCB with no solder mask cutouts looks awesome. This project uses 2 PCBs, one for LEDs and circuitry and the other for the top that you see. The bottom PCB has the battery holder, circuitry, and LEDs. The 2 pieces are just hot glued together. I had less then a second to get them aligned together before it cooled too much. I created a 3D printed align tool to glue them correctly.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
