# Severence-Inspired Lumon Bluetooth Speaker ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/135/812/medium800/3d_printing_hero-pineapple.jpg?1742310488) https://youtu.be/togv3JSCk14 ## Defiant Speaker Build a 3D printed Bluetooth speaker, inspired by the TV Show Severance. Powered by the Feather ESP32 V2 and the MAX98357A 3W I2S amplifier.  This project is written in Arduino and uses two libraries by [Phil Schatzmann](https://github.com/pschatzmann) that make using the ESP32 for Bluetooth audio really easy. Great for playing defiant jazz, watching your favorite TV show, or sync with your mobile device. Just please don't throw it at your coworkers, as it may cause a nasty bump to the head. ![](https://cdn-learn.adafruit.com/assets/assets/000/135/808/medium640thumb/3d_printing_jazz-dance.jpg?1742305956) ## DIY Electronics The speaker, Feather, and I2S amplifier are secured to a 3D printed mounting plate that is affixed to the enclosure. The speaker grill can pop out allowing for any maintenance, if needed. ![](https://cdn-learn.adafruit.com/assets/assets/000/135/809/medium640/3d_printing_hero-spk-open.jpg?1742309318) ## Mid-Century Modern The enclosure design is influenced by minimalism and features curved surfaces that embody a mid-century modern look. The parts can be 3D printed without any support material. ![](https://cdn-learn.adafruit.com/assets/assets/000/135/811/medium640/3d_printing_hero-guide.jpg?1742310465) # Parts Featured ### Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM [Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM](https://www.adafruit.com/product/5400) One of our star Feathers is the [Adafruit HUZZAH32 ESP32 Feather](https://www.adafruit.com/product/3405) - with the fabulous ESP32 WROOM module on there, it makes quick work of WiFi and Bluetooth® projects that take advantage of Espressifs most popular chipset.
