The easiest way to find this is to open up your terminal and type in ls /dev/tty.* I'm not running windows, but this may help.

You need to find the COM port that the bluetooth device is attached to.

Soldering the "T" pin to the HC-06's RXD pin means that the Bluetooth module will siphon off the serial commands and pass it wirelessly over Bluetooth as if it was directly connected via a cable.ĭownload Trent Book's BrainWaveOSC for your platform and unzip it to a folder.īefore you run the application, you'll need to do is identify how your system sees your bluetooth device. The MindFlex also communicates with the base station using a daughterboard that communicates via Serial UART. Soldering the VCC pin to the switch means that the Bluetooth module powers on using the same switch and power supply as the MindFlex. This is perfect because the MindFlex takes 3AAA batteries at 1.5V each when fully charged, which provides about 4.5v. The Bluetooth module has a built-in power regulator and can take anywhere from 3.3v to 5v. If your module did not come with jumper wires, you can solder spare wires to the MindFlex and the HC-06. You can cut and strip them to solder on to the MindFlex, but just make sure that the plug lines up with the HC-06 properly. Your Bluetooth module should come with a few female-female jumper wires. The first two are on the front of the MindFlex PCB, and the last one is located on the back where the switch is.įor the curious, the TXD pin on the HC-06 is used for transmitting serial commands back, the State pin goes HIGH when on and used as a power indicator for an external LED or micro-controller, and the EN pin is used to reprogram the module with different names or baud rates. You'll only need to solder 3 wires, which connect to the Bluetooth module's GND (Ground), RXD (Receive), and VCC (Power) pins. Look through the photos to make sure you have a good sense of what needs to be soldered.

UPDATE: While browsing Instructables, I noticed that arpuss had put up a tutorial using the MindFlex and the HC-06 but goes several steps further to pull raw data from it by switching the MindWave chipset into a different mode by sending a series of hex codes at 57600 baud on boot-up. However, I do not claim to know how this device fully works and take no responsibility for any harm that this project may incur. This is a relatively safe and easy hack to pull off, especially because we're using a commercially available toy and adding a Bluetooth module to it.

In this tutorial, I'm going to show you what to buy, what to solder, and how to get your Bluetooth EEG headset up and running. Turns out, it works almost as good as the commercially available NeuroSky MyndWave for a quarter of the cost, and looks completely unmodified!įinally, I came across a wonderful open source application by Trent Brooks that forwards your EEG signals on via OSC so you can use it in your MAX/MSP, Processing, or other projects. I had a serial bluetooth module HC-06 lying around and decided to see if I could integrate the two and skip the Arduino altogether. It was fun to do, but it still required a cable to be attached, limited mobility, and looked hacked together. I tried out their tutorial and hacked a MindFlex headset using an Arduino. I came across FrontierNerd's Brain Hack tutorial, which gave me a good comparison of the EEG headsets and their capabilities. Last year, I wanted to see what I could control with my brain on a student's budget. Unfortunately, EEG headsets like the NeuroSky MyndWave are a bit too pricey if you just want to experiment. Controlling things with your mind is awesome.
