Pi-powered LED-lit brain sculpture controlled by EEG waves

Pi-powered LED-lit brain sculpture controlled by EEG waves

A person wears a NeuroSky MindWave EEG headset which reads that person’s brainwaves. The EEG communicates with a Raspberry Pi, which will be programmed with software written in Python, and which will in turn talk to the LEDs using a protocol called Open Pixel Control (OPC). The OPC client will send out LED color data packets to the LED strips over Serial Peripheral Interface Bus (SPI), an information transmission protocol that is enabled by default on the Linux distro Mens Amplio is running on their Raspberry Pis.
