Neurofeedback is being studied at several universities. Brainwaves are detected using electrodes and interpreted as control signals by a computer. I was fascinated by the idea of being able to control something with my thoughts, e.g. switch a light on and off. I had an electroencephalography (EEG) to find out whether I was able to generate slower alpha and faster beta waves by relaxing and concentrating. It worked!
The goal of my "Schüler experimentieren" project was to simulate this process in a simplified form. I have been able to reach my goal with idealized alpha and beta waves, a homemade electronic circuit and a program written in C-Control plus.
