Project is focused on the detection and extraction of a brain wave signal with the help of analog as well as digital circuitry. Using active electrodes on human scalp, the brain signals were fed into a series of hardware and software stages. Simple conscious movements such as blinking caused a change in the detected waveform. Although the project was not successful in discriminating between different motions or utilizes the signal to control an electrical device, the team was able to successfully separate and display the alpha waves after filtering off all associated unwanted signals.
