# Sailor Moon Star Locket ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/101/206/medium800/wearables_edited_P1310238.jpg?1617645651) Build a prop from the classic anime and manga Sailor Moon with the Circuit Playground Bluefruit. In the series, the locket is gifted to Sailor Moon by Tuxedo Mask and magically plays a song and shows a crescent moon rotating. Using the magic of CircuitPython and electronics, you can recreate this effect. The TFT Gizmo is used to add a TFT screen and an audio amp without any soldering. A LiPo battery lets you display this as a wire-free prop or make it portable as a snazzy wearable. ![wearables_edited_P1310197.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/208/medium640/wearables_edited_P1310197.jpg?1617645986) The 3D printed snap-fit case gives the illusion of a solid locket. The top frame that sits over the Gizmo's TFT makes the screen appear to be a circle. ![wearables_edited_P1310202.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/209/medium640/wearables_edited_P1310202.jpg?1617646581) By default, a crescent moon will rotate around the screen. You can also press the buttons on the back to hear a song played through the speaker and to pause the animation. ![wearables_edited_P1310239.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/249/medium640/wearables_edited_P1310239.jpg?1617723312) ## Parts ### Circuit Playground Bluefruit - Bluetooth® Low Energy [Circuit Playground Bluefruit - Bluetooth® Low Energy](https://www.adafruit.com/product/4333) **Circuit Playground Bluefruit** is our third board in the Circuit Playground series, another step towards a perfect introduction to electronics and programming.
