NeuroLab - Open Source Brain Wave Analyzing Tool

DESCRIPTION

This project is inspired from another open source project known as Neurofox.

The goal of the Neurolab project is to develop an easy to use open hardware measurement headset device for brain waves that can be plugged into an Android smartphone and a software application that enables us to understand our brains better.

Our brains communicate through neurotransmitters and their activity emits electricity. The neuroheadset measures that electricity on the skin of the forehead and the software processes the signal so that it can translated into a visual or auditory representation. The data that can be collected can be analysed to identify mental health, stress, relaxation and even diseases like Alzheimer.

Current devices in the medical industry are usually not accessible by doctors due to their high pricing. They are also complicated to use. The idea of the device is to integrate it into a headband and focus on signals that can be obtained through the frontal lobe.

TECHNICAL DETAILS / COMPONENTS

The device uses a set of stages of signal processing to output a digital signal which represent each brain wave frequency set. This data can be then fed into a Teensy or an Arduino Pro Mini using SPI protocol. Captured data can be visualized using the already available desktop app and the yet to be developed Android app. 

LEARN / TOPIC / BUILD INSTRUCTIONS

Once the PCB is assembled, you need a set of electrodes to connect around forehead. The circuitry will fed with electric pulses captured by the electrodes and they will be processed down the road to microcontroller. There can be a HC04/06 bluetooth module connected to the socket on the bottom right corner and have a wireless connectivity with a mobile phone.
