Reactive Brain Waves
summary
Connects a web Bluetooth headset (Muse) to a browser app using the muse-js wrapper and Angular, streams EEG samples as an RxJS observable, reduces each 12-sample packet to a positive max, filters above 100 threshold, uses switchMap + 300 ms timers and distinctUntilChanged to emit blink true/false, and binds that observable in the template to animate an eye emoji. Live demo is flaky but works; the prototype takes about 8 lines of JS to detect blinks and can drive a lightbulb or a blink-controlled game.
