MIXER32

🎛️ Mixer32 - Wireless Audio Controller for PC (Linker32 Ecosystem)

Mixer32 is the official enclosure and physical hardware for the Linker32 ecosystem, a system designed to give you absolute, physical, and tactile control over the Windows volume mixer and your multimedia content

Forget about Alt+Tabbing in the middle of a game or a meeting. With Mixer32, you can isolate channels, mute the microphone, or lower the volume of Spotify, Chrome, or Discord independently using a rotary encoder and mechanical buttons, all with real-time visual feedback thanks to its OLED screen

📐 About the 3D Design

This enclosure has been designed for maximum ergonomics and a professional finish:

• Angled Screen: Housing for an OLED (SSD1306) screen with the perfect inclination to be read at a glance from your chair
• Mechanical Buttons: Front slots with ergonomic inclination designed to mount 3 Cherry MX mechanical switches (or clones), providing a fast and satisfying feel to the multimedia controls (Previous, Play/Pause, Mute)
• Master Control: Top space for a KY-040 rotary encoder with support for a large knob (SOLO / Volume function)
• Portable Design: The interior has enough space to house an ESP32, a TP4056 charging module, a LiPo battery (e.g., 2000mAh), and a side slot for a power switch (SS12F15VG4), making the device 100% wireless via Bluetooth

💻 The Software: Linker32

This enclosure is not just an ornament. Mixer32 comes to life thanks to Linker32, a desktop application developed in C# .NET that runs in the background on your PC. Linker32 extracts Windows audio sessions, communicates with this hardware via Bluetooth, and features OTA (Over-The-Air) Updates, meaning the peripheral updates itself wirelessly
