Re: Problems with Signal

Where is it? Is it sitting next to a 120VAC 60Hz/50Hz source it might be
picking up? If it's not the impedance of the electrodes, the nearest source
of 120VAC 60Hz/50Hz would be the next suspect. I'm an Electrical Engineer
who owned my own Factory Authorized Service Center for ten years between
1985 and 1995 in the Atlanta area and I would be interested for just that
reason.

However, I'm also a Nocturnal Epileptic trying to get control of these TC
seizures and am currently trying to put together my own EEG here at home. I
knew long ago these cell phones were going to be the perfect control
stations and would easily be everything from PC's to Cameras to everything
in between including my own EEG. So, I'd like to put together all such Radio
Shack components for my own EEG receptors that I can attach from my head to
my phone via the earpiece. 

To see just one of my on-going accomplishments, check out www.SpecificUV.com
just to see what has been done and what I'm trying to do.

Thanks so much! ;-)

looks like 60Hz/50Hz noise. you might want to check the impedance of the
electrodes.

Hey guys, 

i build the ModularEEG with 2 Channels and im getting this Signal in the
picture attached. 

My amplifier PCB is in a metal box and i use active electrodes von Olimex
and a passive electrode as the referenz from olimex, too. 
Can someone explain to me why i am getting such a bad signal? my wires are
shielded too... 

Thanks..
