BCI part 8 – Getting Processing and BrainGrapher working on the Raspberry Pi

Sep 14, 2014 | | Say something

Searching the Internet it says it is possible to get Processing working on the Raspberry Pi. There are several similar but different accounts of how to do this. I found that the ones I tried did result in a working version of Processing on the Raspberry Pi, however none would run the BrainGrapher sketch. More [...more]

BCI part 7, the brainwaves

Sep 9, 2014 | | Say something

This post says something about the origin of brainwaves and gives some information on their significance. A good description can be found at https://learn.sparkfun.com/tutorials/hackers-in-residence—hacking-mindwave-mobile. I make no excuses in this section being my own work, it has been direct from the quoted source. The 5 types of brainwaves measured and reported originate from different parts [...more]

BCI part 6 – The Visualisation Software

Sep 9, 2014 | | Say something

In previous posts I have described how to modify the Mind Flex headset to give a wireless link to an Arduino running the brain-master library. Here I describe in more detail the data output from the TGAM1 module and how the Arduino is connected to the visualisation software to display the brain wave data. A [...more]

BCI part 5 – RF Link between Headset and Arduino

Sep 9, 2014 | | Say something

In the previous part, I described a simple wire connection to the Arduino as an initial test configuration. Here I describe a radio link between the Mind Flex headset and Arduino. The modifications on the Internet all make use of a wired connection between the headset, Arduino and host computer for visualisation, the one exception [...more]

BCI part 4 – the Arduino hardware and software

Sep 9, 2014 | | Say something

My previous post described how to make a simple wire modification to the Mind Flex headset, here I describe setting it up for initials tests on the Arduino. I have for testing an Arduino UNO, and it connects to my laptop using a standard USB A-B cable. You will need an environment for the software, [...more]

BCI part 3 – The basic Headset simple modification

Sep 9, 2014 | | Say something

In the preceding post I described in detail the inside electronics of the Mindflex headset, especially the connections to the NeuroSky TGAM1 module. Here I describe the basic modification of the headset as covered elsewhere on the Internet and then explain some of the safety issues of wired connections to an Arduino and beyond. At [...more]

BCI Part 2 – The Mind Flex Headset, Inside and Out

Sep 9, 2014 | | Say something

In the first part I provided some background on the Mindflex toy and how people are hacking this to provide a cheap brain computer interface. In this second part, I look more in-depth and technical at the workings of the headset. The duel comes with two headsets; only one is needed for the BCI, so [...more]

A cheap Brain-Computer Interface (BCI) – Part 1

Sep 9, 2014 | | Say something

Recently at The Southend-on-Sea Linux User Group (SoSLUG) Jam, I saw demonstrated a system using brainwaves to control radios http://www.timeleapji.com/mindio.html I only managed a very brief chat with Ji Hu as she had to catch a train, but I was impressed with what she had accomplished. A little bit more about her system “Mindo” and [...more]
