Turned a $2 Bluetooth selfie remote into a physical push-to-talk clicker for agentic coding
_7xen_on · reddit · 2026-09-19
A developer repurposed a $2 AB Shutter 3 Bluetooth selfie remote into a physical push-to-talk button for Google Antigravity's voice dictation (Ctrl+M), so you can prompt agents while pacing around instead of sitting at the keyboard.
How it works: the remote pairs as an HID keyboard emitting volume keystrokes. A lightweight Python daemon (15MB RAM, silent via pythonw, auto-start batch script) uses a WHKEYBOARDLL low-level hook to intercept and suppress the key so the Windows volume HUD never flashes. Single click focuses the Antigravity window across monitors and toggles the mic; double click stops dictation, waits for transcription to settle, and fires hardware scan code 0x1C to submit; Shift+Click passes through the original volume key. Audio beeps confirm actions. Code and setup guide are open-sourced on GitHub.
