Lets Start: Initial software test to make sure your mind Flex is talking to the Arduino: Run the example BrainSerialOut sketch. (If you are familiar with processing, I recommend you try their project.
#HEMI SYNC MEGA HOW TO#
For those folks that live overseas you may need to change the 60 hz filter to 50 hz, as described in the datasheet to avoid powerline interference.Īs I mentioned before, the guys at frontiernerds have done an excellent job at explaining how to perform this hack and of how to interface the Mind flex headset to the Arduino and graphing the output using Processing (which I did and worked fantastically!), so I will only go through the steps of getting the data to display on the mini monitor. Note: I have Included the Neurosky Datasheet in case you need more clarity. We are done with the hardware part of the Hack. 10.- Connect the Mind Flex to the Arduino Connect the Wire coming from the T pin to the Arduino rx pin, Connect the other wire to an arduino GND pin. 9.- Carefully put the back case back on and re secure the screws. I recommend putting a dab of glue in the hole to secure the wires in place ( I used my hot glue gun to do this). Guide the wires through the hole, and recheck your soldering. Drill a hole in the case for the two wires to poke through after the case was closed. 6.- Solder another length of wire to ground using the large solder pad where the battery’s ground connection is. Be careful not to short the neighboring pins. I used a pair of wires that came from an old PC. 5.- Solder a length of wire (carefully) to the “T” pin. 4.- If you look closely, you will see pins that are labeled T and R - these are the pins the EEG board uses to communicate serially to the microcontroller on the main circuit board. 3.- Identify the NeuroSky Board.It is the small daughterboard towards the bottom of the left pod. 1.- Remove the 4 screws from the back cover of the left pod of the Mind Flex headset.(The right pod holds the batteries.) 2.- Open the case to expose the electronics. Please review the pictures and comments for more detail. For Purposes of completeness, I will quickly go through the steps I took to hack my headset. You will need to have the Mind Flex headset.

So lets start with the EEG Monitor: Before attempting to start this phase, I recommend you visit the Frontier Nerds web site, Where they do a better job than I could, of explaining how to mod the MindFlex headset so you can interface it with the arduino. Brain brain(Serial) void setup(void) Īs I mentioned before,I will be Developing this project in various phases because I'm not quite sure how it will all come together yet, and whether the Arduino will be able to handle it all.
#HEMI SYNC MEGA SERIAL#
this sketch was created using code from both the adafruit and the Braintest( by Eric Mika, 2010 ) sample sketches // You can use any (4 or) 5 pins #define sclk 4 #define mosi 5 #define cs 6 #define dc 7 #define rst 8 // you can also connect this to the Arduino reset #define ANALOG_IN 0 // for cds light sensor #define ANALOG_IN 1 // for temperature sensor #include // Core graphics library #include // Hardware-specific library #include #include Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, mosi, sclk, rst) // Set up the brain parser, pass it the hardware serial object you want to listen on. Note : you don't really need to do this step, it's just for documentation purposes Below is the preliminary code to check out the screen layout of the data we want to display // copy the sketch below and paste it into the Arduino IDE compile and run the program. That said, practical uses of this monitor are biofeedback - meditation aid, lie detector toy, heart rate monitor / logger, etc. EEG Brain wave values of: Attention Meditation Alpha Beta Delta Gama DISCLAMER: This project is not intended to be used as a medical device, use of this device for those purposes is at your own risk.
#HEMI SYNC MEGA INSTALL#
Basic assumptions: I am assuming that you already know how to download and install Arduino libraries, and that you have at least constructed the mini environment monitor, as the same skill-set is required, The Vital signs we will eventually, be monitoring are: Heart Rate Body Temperature GSR But in Phase 1 we will be Monitoring.
#HEMI SYNC MEGA PORTABLE#
I will be working on several phases until I complete a " Portable Human Vital Signs monitor" I will be using the mini monitor setup that I used in my mini environment monitor, so I won't go into any of the details about building the monitor here. This is another example of the versatility, and of what, the Arduino, a small LCD Color display and the right type of sensors, are capable of doing.
