Getting VNC working on Raspberry Pi

Sep 14, 2014 | | Say something

VNC is a program that allows one computer to remotely view and control another. There are many versions of VNC, it will need to be installed on the Raspberry Pi and also any other computer that it is desired to access the Rpi from. It does not have to be the same version on both [...more]

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]

How I got started and a bit more background on me

Sep 9, 2014 | | Say something

I have always enjoyed electronics since the age of about 8 or 9. One day I went to work with my dad, a heating and ventilation technician who was in charge of a number of heating control systems in government buildings. I was fascinated by the giant control panels, about 2m high and running a [...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]
