Active Electrode Building Guide. [Up to my homepage] IMPORTANT NOTE: Please do not contact me about the active electrodes.

Active Electrode Building Guide

You will get more help if you send an email to the OpenEEG mailing list. Also, check out Olimex if you're interested in buying a preassembled active electrode. This guide should help you to build Active Electrodes for the modularEEG, as proposed by Jarek Foltynsky here. The active electrodes described here correspond to the modified circuit diagram suggested by Joerg Hansmann: This guide proposes a tradeoff between building simplicity and signal quality. MindFlex xbee eeg hack. Heyo guys, this is my last ultimate hack for the mindflex.

MindFlex xbee eeg hack

I wanted to reproduced the results of the mindflex as indicated by the manufacturer.The simplest test that can be done with an EEG device is to check if the alpha waves go up significantly when closing your eyes. However doing some test with different subjects (i.e. my guinea pig students/friends) and with or without electrogel I couldn’t find any prove that the neurosky chip is working properly. I will be happy if somebody can reproduce a high alpha activity with closed eyes.

I could only see some random peaks in the alpha activity during closed eyes which were not stable. So you take out of the shell 3 wires: black is the GND, blue is the Vcc=3.3V and white is the TTL signal at 9600 bauds. Stream directly to the computer and one which uses a xbee transmitter and an xbee receiver. As I said before I totally desoldered the original radio modem that was on the main board inside, as in Figure.

Mindflex hack. Arturo Vidich, Sofy Yuditskaya, and I needed a way to read brains for our Mental Block project last fall.

After looking at the options, we decided that hacking a toy EEG would be the cheapest / fastest way to get the data we wanted. Thinking Cap. Alternatives: An alternative to finding electrodes and doing all the amplification DIY-style, it's now possible to purchase a single channel off-the-shelf headset from Neurosky which sends the raw EEG via bluetooth.

In addition to potentially being easier to set up and using dry electrodes, this system also ensures user safety by removing the user from any possible shock hazards associated with being attached to wall power. The major drawback is that it has only a single channel, but maybe this will improve in the next version. Mindmachine. Solson EEG. Around 1967 a fellow named Maurice "Barry" Sterman discovered that cats could be trained to alter their brain waves, and that these same cats were less susceptible to having seizures when injected with monomethylhydrazine (rocket fuel); hence the start of some very interesting research into neurofeedback.

I was told of two books on the subject, which I have purchased, read, and would recommend: A Symphony in the Brain, by Jim Robbins, and Getting Rid of Ritalin, by Robert Hill and Eduardo Castro. I have purchased and would NOT recommend ADD The 20-Hour Solution by Steinberg and Othmer. Only click this if you want to hear me rant. Biosemi. OCZ Neural Impulse Actuator. EEG/EKG Schematics by +1+1+1. EEG & EKG (ECG) Schematics last updated 7-Jan 2005 I developed my 4-channel, dual-purpose EEG/ECG box between September 2003 and March or April of 2004 with the gracious help of David Rosenboom at Calarts for use in my medi[t]ations sound performance series.

EEG/EKG Schematics by +1+1+1

We combined schematics from his book Biofeedback and the Arts (available thru Frog Peak Press) with schematics from the article "Computers On The Brain" by Steve Ciarcia (in the June 1998 issue of BYTE magazine). We are also indebted to Ronald Kuivila who was instrumental in unlocking the mystery of how to get the low-frequency audio signal into my computer and subsequently into SuperCollider... WARNING: USE AT YOUR OWN RISK. OLIMEX. ModularEEG.

General information The ModularEEG device is made up of two or more EEG amplifiers, and a 6-channel signal capture board that connects to a PC via a standard serial cable.


The standard setup has two EEG channels. As with any EEG device that you build yourself, there is a risk of injury involved. Make sure you read the WARNING file below. The cost of a complete system is 200 to 400 USD. Brainclinics. Brainclinics is specialized in personalized medicine, applied neuroscience and neuromodulation techniques such as rTMS and Neurofeedback and is involved with scientific research in these fields.


We also regularly provide courses and workshops on these topics. On this section of the website you can find different products that are used in applying these techniques in practice. J&J Engineering. QDS System. BioExplorer Software BioExplorer is a Windows program for real-time biophysical data acquisition, processing, and display.

QDS System

It is intended for personal use in entertainment, education, and experimentation. BioExplorer version 1.3 is now available for download this version is needs the Hasp Key. MonolithEEG_e. ● miniaturised to 3.8 x 2.4 x 1 Inch (101 x 61 x 26mm) ● limited to 2 EEG channels each with 10 Bit resolution ● only one circuit board equipped with SMD components ● Designed for a Pactec JM 42-000 case ● USB via FTDI232 ● Supply voltage from USB.


OpenEXG. Last Updated: 21 April 2009. Pceeg. ScEEG. Sound Card EEG (ScEEG) Technology This web site is focused on sound card EEG hardware and software experimentation to create a Brain-to-Computer Interface (BCI). Several types of EEG units have been built to date, a dual channel AM unit, a dual channel FM unit, A four channel AM unit, and a four channel multiplexed unit. The FM unit uses approximately 4.5 kHz of audio spectrum per channel while the AM unit uses approximately 2 kHz of spectrum (with some guard band allocation) per channel.

The first attempt in building a prototype sound card EEG unit was begun in July 2005 . The first unit consisted of a two channel AM modulated version with a built-in power supply. The second prototype was a single channel AM unit that reduced the modulation circuitry and the size of the unit was reduced to 2" by 4". A new software application (EEGProbe2) was developed specifically for EEG display and instrumentation. Single Channel FM Unit 1. 1 EEG signal channel 2. Two Channel AM Unit.
