Use Circuit Playground to make a classy seashell necklace that goes with every outfit. Change colors and brightness on the fly with a click of Circuit Playground's onboard buttons. We even included a sound reactive mode to invoke Ariel's necklace from the Little Mermaid. This is an easy project that kids of all ages will adore.
A Particle Photon microcontroller and an Adafruit Neopixel ring combine to make a pin that's fit for NASA fans. It displays an orbiting white blip when idle and then turns blue, white and red when the ISS flies by. The code makes use of IFTTT (If This Then That), a free site that makes connecting IoT devices as easy as a few clicks. This project was inspired by my first NASA Space Apps Challenge with friend Brooks Rampersad--an ISS Orbit Skirt.
This project turns a toy hammer into a magic wand that produces different sound and light effects depending on the spell cast based on simple gesture recognition. The amount of components in this project combined with the small room requites a bit of cramfu to get all the parts to fit. The compact nature of this project and the number of components means it's a best for a somewhat experienced maker.
