Last Tuesday at 3 AM, I trained my first model to detect pupil dilation from my laptop’s webcam. No IR sensors. No chest straps. Just raw RGB and a PyTorch script. After 72 failed epochs, it caught my stress spike when I spilled coffee. That moment, EmoPulse was real. Now it tracks 47 distinct biometric signals — all in real time, all from one camera. I’m building this solo, no lab, no legacy hardware. Just code, biology, and obsession. Follow @emopulseai on Telegram for daily AI insights -> t.me/emopulseai
