Gaming Control Using a Wearable and Wireless EEG-Based Brain-Computer Interface Device with Novel Dry Foam-based Sensors. Acquérir des signaux EEG de votre cerveau avec un kit Arduino. Voici une technique simple qui permet de connecter un simple gadget utilisant vos EEG à un kit Arduino.
Vous pouvez ainsi développer de nouvelles applications utilisant l’électroencéphalographie. Une dérivation est réalisée sur le gadget pour être acquisse par le kit Arduino qui mettra en forma les données à l’aide d’un Parser. Dans l’exemple qui suit en vidéo, c’est un modèle de capteur MindFlex de Mattel qui est hacké par un kit Arduino. DIY EMG uses an audio recorder. EEG Page. EEG Probe. EEG for the braindead « Unlocking the secrets of the mind… I was hoping to start this blog yesterday but I couldn’t find the time coz I went for a rock show.
This little project is a resurrected version of something similar I worked on a few years ago. A lot of my inspiration comes from the OpenEEG project. So, if you’re ready for the ride, let’s begin! EEG Schematic « Unlocking the secrets of the mind… Alright, so here it is!
Finally, after all that experimentation, it all boils down to this. As of now, this schematic incorporates only ONE EEG channel measured by an INA118, which is then fed to an inverting amplifier followed by a Fliege Filter (cut off frequency is set at 33.86 Hz). I previously used a dual supply to power the circuit, but with the help of TLE2426, I’ve been able to use just a single +5V supply (which comes from a 7805 connected to a 9V battery). If you have any questions at all, feel free to post here or email me at: EEG schematic For the electrodes, I got good results by replacing the gel layers in medical electrodes (already used) with sponges soaked in warm saline water.
Resources / EEG/EKG Schematics. 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.
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... EMG Biofeedback. This biofeedback setup uses an EMG sensor to represent muscle tension as a series of beeps and allows you to train your body to adjust muscle tension at will.
In short, the more tense you are, the faster the beeps become, and the more relaxed, the slower. Using this device you can learn how to regulate your body to speed up and slow down the beeps; hence increasing and decreasing muscle tension. With some practice, you will have enough understanding of your body to be able to control muscle tension without use of the device. Pulse Oximeter. Pulse Sensor: an Open Source Heart-rate Sensor that Rocks by Yury Gitman. * We've been getting great questions from our backers and are building a FAQ at the bottom of this page.
If your question is not there, send us a message and we'll get back to you! “Pulse Sensor” is a well-designed plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. OpenBCI. Simple ModularEEG. The idea of this page is that, if you follow the directions in the "Simple" column, you will have a ModularEEG with a minimum of fuss.
The Links columns is reference material, often with ways of doing things more cost effectively (although this usually involves more fuss). The links will give you more information, some of which may be relevant. Just a warning that, although these are the simplest instructions, they still involve putting the PCBs (see below) in a case and wiring them to the case. So maybe "Comparitively simple" would be better. Term definition: PCB = Printed Circuit Board. Assumptions you will need to make: You already know why you want an EEG, have done some background reading, and have read the WARNING. Open source neural activity monitors. Medical and Health Related Projects with Arduino. Projects/BioSensor.
From OLPC Name: Paola Lira City: Lima (Peru) Email: arilyes at yahoo.com I would like to design a low cost sensor for sensing pathogens and contaminants in food, water and soil.
I would develop a permittivity based sensor for real time sensing of pathogens and contaminants. Each individual sensor or a group of them can be functionalized for a given specific target: E. coli, Streptococcus, Staphylococcus, Salmonella, Hg, Pb, As. With the use of mathematical algorithms, the rate of positive events provides data about the concentration of the target pathogem or contaminant. The sensor will use low costs chips and insumes for sample preparation. Bio-Sensing. Thermographic camera. Image of a small dog taken in mid-infrared ("thermal") light (false-color) A thermographic camera or infrared camera is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light.
Instead of the 450–750 nanometer range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm). History Precursors
