ADS1299 EEG Headset 🧠

This is a DIY / custom electroencephalogram reading device which is connected eeg electrodes that can connect to brain at designated areas.

It reads brain wave signals and digitizes them into the computer which is called brain-computer interface.

Why am i doing this

I have a larger project and i want to join the competition with my pcb.
