Show HN: Open a browser by clapping twice (inspired by Iron Man)
https://github.com/Yutarop/two_claps_open
Recently, I watched Iron Man and was inspired by the scene where Tony Stark claps twice to activate his computer. (https://www.youtube.com/watch?v=OT2b5KzMoC0&t=101s) I thought, “I want to try that!".So I wrote a simple script that opens Google Chrome — and optionally a local file — when I clap twice.
Technically, I recorded sample clap sounds and analyzed their frequency content in MATLAB (most energy was around 1.4–1.8kHz). Then I built a real-time detection system in Python using a bandpass filter and peak detection to recognize claps and trigger an action.
Is it practical? Maybe not. But it’s fun. Imagine this: you're about to Netflix and chill and open Netflix with two claps. Or you're about to give a presentation and launch your slides like Tony Stark. Just clap twice.
