Neuro-Feedback Alpha Training Headset Kit with ESP32 + LED
Build a Professional Neuro-Feedback Headset for Alpha Relaxation Training with ESP32
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced wearable kit lets you construct a functional neuro-feedback headband that detects frontal alpha brainwaves using a medical-grade ADS1299 EEG front-end, and instantly reflects your relaxation level through a colored LED ring and audio tone. Designed for researchers, therapists, and serious makers in India exploring brain-computer interfaces.
What You'll Build
A comfortable headband with four snap electrodes on the forehead, connected to a custom PCB that processes EEG signals on the ESP32. The device extracts alpha-band power (8-12 Hz) in real time, mapping the intensity to an LED ring’s color and brightness. A speaker emits a calming tone that shifts pitch with your alpha activity, creating a closed-loop relaxation feedback system. All firmware is open and customizable.
What You'll Learn
- Configuring the ADS1299 for low-noise EEG acquisition with proper electrode connections
- Implementing digital filters and FFT on ESP32 for real-time alpha band power extraction
- Designing a neuro-feedback loop that maps EEG data to LED ring colors and audio tones
- Integrating microSD and RTC modules for time-stamped data logging and offline analysis

Who This Kit Is For
This advanced kit suits graduate researchers in biomedical engineering or neuroscience, psychologists integrating biofeedback into therapy, and hardware developers building wearable health devices. Ideal for final-year B.Tech projects at IITs, NITs, VIT, or BITS Pilani, and for institutions prototyping affordable EEG tools for India.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to access the AI companion that knows every step of this EEG kit. You can also message our engineers via WhatsApp for direct troubleshooting.
Do I need previous experience with EEG hardware?
While this is an advanced kit, the build companion walks you through soldering, electrode placement, and firmware configuration. Familiarity with Arduino IDE and basic signal processing concepts is recommended, but not mandatory.
Can I use this kit for clinical neurofeedback therapy?
This kit is for educational and research purposes. It is not a medical device, but it closely mirrors the signal chain of professional neuro-feedback equipment, making it suitable for academic and prototype work.
What is the battery life of the headset?
With a fully charged 1000mAh LiPo battery, the ESP32 and EEG module can run continuously for about 3-4 hours of alpha training. The TP4056
ADS1299 records frontal EEG. Real-time alpha band power feedback via LED ring and tone guides relaxation.
