BioWave for Sale

used only for testing. this sensor is excellent at picking up muscle movements, so that, with the [dac] object in the Max patch you can literally play for forehead muscles like an instrument!

Re: How to get EEG, Alpha waves from BioWave1.1?

Hugh, in order to help with advise on how best to use the sensor, you asked for information on the piece I am trying to produce for which the BioWave is the data acquisition device, so what follows is a project description: What I have in mind is a screen based real-time art installation in which th...

Re: How to get EEG, Alpha waves from BioWave1.1?

so as the post above shows, i managed to get what looks like alpha waves out of the sensor, hooray! while that can be seen as a minour success it also brings up more issues: for 1.) one i had from some technical difficulties getting the thing to work at all, 2.) second, i have found it hard to repea...

Re: How to get EEG, Alpha waves from BioWave1.1?

after havingat first placed the sensor on my head as you suggested hugh, and just got 10 minutes of flatline, suddenly i got the sensor to work (don't ask me what happened it just suddenly started to work) i feel like i managed to actually produce alpha, with the help of strobosopic flicker <www.netliberty.net/dreamachine.html> and this is what it looks like (the second attached image), compared with just the noisy baseline below. so now, the challenge is if there is enough of a clear difference that i can use some kind of beysian filter, or some such thing, so that i can use only the alpha. i have to be careful, cause there's a lot of random fluctuation from just moving the ears, or even moving the head at the neck.

Re: How to get EEG, Alpha waves from BioWave1.1?

here's something odd, after keeping the sensor on my head for 10 minutes (i had wet it at the beginning and got a flatline as the previous post illustrates), quite suddenly, and for no apparent reason, the sensor just kicked int and started to give me something that looks more like eeg data

Re: How to get EEG, Alpha waves from BioWave1.1?

the screengrab below shows what MAX shows me when i wear the headband as you instructed. if i move it closer to the kneck as you tell me not to do i get more interesting data. i understand that MAX may not be the final solution for the fine grained data i'm looking for, however, why would it give me...

How to get EEG, Alpha waves from BioWave1.1?

I am trying to work out how to gett EEG data out of the BioWave1.1. Specifically, I'm trying to figure out how to get Alpha waves as shown in the pdf that accompanies the product. Mounting the 3 sensors at the back of the head, I'm using the MAX and, so long as the sensors are mounted lower down the...
