We actually began using the 'electrodes'that we etched onto a pcb board. My
group seems to have made no progress on any filtering, so I figured it would be
best to see at least if the electrodes picked up any signal at all.
Surprisingly, they did. Mustafa and I met in the lab downstairs and actually
connected them up to my head, bringing each node down to a instrumental
amplifier (in difference amp configuration). We actually saw results on the
scope (didnt take pictures, we will next time)
Unfortunatly the signal is swamped by noise, we could not use autoscale but
had to adjust the settings manually. We also tested the probes using a 100mV
test signal, even this could not be found with autoscale. After this, we wanted
to see if there were any spikes caused by blinking, we set the scope to track
min and max of the signal, but somehow the data got corrupt and scope the
claimned the max was 160V or something ridiculously high. There is only +-5V
being supplied to the amp so obviously that was ridiculous. We need to adjust
the output to be from 0-5V.
