Inside the Cylon Vocoder: Mark’s 3D Printed Pumpkin Build Explained

Mark combines two of his past builds, the Larson Scanner and the Vocoder, into a single 3D printed “Cylon Pumpkin” for Halloween 2025. The project features a reusable 3D printed pumpkin shell with a sweeping LED eye and a built-in voice-modulating vocoder powered by a Teensy microcontroller. In this video, Mark walks through the design in Onshape, PCB assembly, soldering, firmware setup, and how it all fits together to create a talking, glowing pumpkin that’s perfect for Halloween decoration or cosplay: https://bit.ly/3L73pgS
