Hello instructibles!! I just made something really really cool. Its not quite mind reading but it sure is close! I have made an arduino powered eeg machine, also known as Electroencephalography machine. Now normaly these will cost you lots of money and are hard to understand without a degree in neuro science, but this arduino version is much cheaper and easier! So you might be asking... What does it do? In short it reads brainwaves that are created by your brain. This allows us to tell how much a person is paying attention or if he/she is deppressed or in an emotional state.
Step 1: Required Materials
1: a mindflex eeg headset (must have a nerosky brand control board inside)
2: an arduino
3: a usb cable
4: a computer
5: basic tools (screwdriver, multimeter, wire-snips)
6: a soldering iron
Step 2: Dismantle the Headset
Now look for the smaller circuit board with 6 pins sticking out and a label saying "NeuroSky" after you have found that board, go and solder a wire to the pin that is labeled T and then solder another one to the pin on the bigger board that has a black wire connecting to it.
Step 3: Hookup the Arduino
Step 4: Wrap It Up
Step 5: Upload Some Code
Open the serial monitor to see if you are getting csv data from the headset.
Step 6: See Your Mind
And get the brain grapher code here:
Then run it while the Arduino is on and sending data. And with enough fiddling with the connection quality indicator you should get realtime brainwave data.
Step 7: Your Done!
