This is a basic EEG toy built for MindFlex's ThinkGear headset.

• MindFlex Headset -- you can get one relatively cheap on eBay.
• HC-06 Bluetooth transciever -- see Amazon.
• Any TTL link -- for changing the baudrate on HC-06... an Arduino will work

• Solder connections to the T (transmit), R (recieve), ground, and power pins in the ThinkGear headset
• Set HC-06 to 57600 baud with command AT+BAUD7 via TTL (only necessary once)
• Connect HC-06 to the ThinkGear headset

There are more detailed setup instructions below in the references.

Setup: run pip install -r requirements.txt for python dependencies

• Connect to the HC-06 via bluetooth
• Run mindflex.py

Note, mindflex.py will switch the ThinkGear into Mode 0x02 by sending the following command over 57600 baud after each power up: 0x00, 0xF8, 0x00, 0x00, 0x00, 0xE0.

Example response data:

{
	'quality': 0, 		# Signal strength (0-200, lower is better)
	'attention': 100, 	# NeuroSky attention score (0-100)
	'meditation': 75 	# NeuroSky meditation score (0-100)
	'eeg': [			# Array of eight FFT values
		1572953, 		# Delta
		14811157, 		# Theat
		7077897, 		# Low alpha
		14876686, 		# High alpha
		14417931, 		# Low beta
		3932175, 		# High beta
		7208965, 		# Low gamma
		4784137], 		# Mid gamma
}
