This advanced kit equips you to build a wearable EEG headband that detects alpha waves (8–12 Hz) in real time. Using the high-precision ADS1299 analog front-end and the ESP32’s dual-core processing, you’ll capture minuscule scalp potentials, filter out noise, and generate a live relaxation index displayed on an OLED and an LED. Whether for neurofeedback research, a B.Tech capstone project, or personal biohacking, you’ll create a fully standalone device that logs timestamped data for offline analysis.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA battery-powered EEG headband that continuously samples the visual cortex at 250 Hz. In a relaxed state, alpha power increases and the onboard LED brightens proportionally. The OLED displays the alpha envelope trend, and the microSD card stores raw signals and processed metrics alongside an RTC timestamp. The AI companion provides a 3D-printable case file to finish your wearable, lab-grade alpha meter.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSampling high-resolution EEG with the ADS1299 at 250 Hz via SPI\u003c\/li\u003e\n  \u003cli\u003eImplementing digital bandpass filters on the ESP32 for alpha band extraction\u003c\/li\u003e\n  \u003cli\u003eReal-time signal processing and data logging with a DS3231 real-time clock\u003c\/li\u003e\n  \u003cli\u003eDesigning wearable, low-noise analog front-ends for biopotential measurements\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u0026lt;\n\n\u003cdiv class=\"kit-description\"\u003e\n  \u003cp\u003eADS1299 EEG front-end samples brain signals at 250Hz.
