What is dvs-wireless-diy-dj-system?

This project is a low cost, do it yourself wireless DVS system for DJs. DVS stands for Digital Vinyl System, a technology that lets DJs control DJ software using a real vinyl record on a turntable. Normally the turntable plays a special timecode record, and software reads that signal to control playback speed and direction. Commercial wireless versions of this, such as Phase DJ, are expensive, this project builds a similar setup cheaply using off the shelf electronics. The system uses two small microcontroller boards called ESP32s. A transmitter board (ESP32-C3) is mounted on top of a vinyl record on the turntable. It contains a gyroscope, a motion sensor, that detects how fast and in which direction the platter is spinning, and sends that data wirelessly to a receiver board (ESP32-S3) using a fast, low latency wireless protocol called ESP-NOW. The receiver takes the speed and direction data and uses it to generate a timecode audio signal in real time through a small audio chip called a PCM5102 DAC. That audio signal plugs into a DJ mixer or audio interface, which connects to DJ software that responds to it. The project is written in C and runs in the Arduino IDE using the ESP32 board package from Espressif. No external libraries beyond what comes with that package are needed. The README includes wiring diagrams, hardware recommendations, and setup instructions, and is explicit that this DIY version will not match the precision, latency, or reliability of a professional commercial system. This is intended for makers, DJs, students, and developers who want to experiment with wireless vinyl control on a budget, released under a non-commercial license that permits studying, modifying, and sharing the project but not selling it.
