EEG-Headset
About the EEG-Headset PCB
EEG-Headset is an open source PCB design by MohamedAlDeep, published on GitHub. It is a 2-layer board measuring 113 × 110.5 mm, with 83 components from 19 distinct parts.
Other key parts include the ADS1299xPAG, LM7805_TO220 and AMS1117-3.3. By type, the board carries 31 connectors, 23 resistors, 21 capacitors, 3 ICs, 2 transistors and 2 diodes.
From the project
This is the main board for EEG reading headset, in which it uses an analogue to digital converted (ADS1299) chip. Such devices made by companies are expensive, the goal is to make it using the same components but DIY.
It reads brain wave signals and digitizes them into the computer which is called brain-computer interface.
