Building a Real Star Trek Communicator Badge with an ESP32-S3 & SIM800L

Published at : 23 Dec 2025

Clem Mayer builds a real working communicator inspired by classic sci-fi — a handheld badge that actually makes phone calls. Powered by an ESP32-S3 and a SIM800L GSM module, this device bridges retro design with modern engineering. From 3D printing the conductive case to debugging AT commands in Arduino, Clem walks through every step of creating a fully functional 2G cell phone disguised as a lost-era communicator: https://bit.ly/4ooLTmK
