Hi all, 

Finished assembling my Cyton+Daisy 16 channel setup. Unfortunately I get this horrible artifacts on all channels (see below). All input electrodes are connected to the low pins. 
Both SRBs are connected via Y cable to left ear and BIAS of Cyton connected to right ear.

What am I doing wrong? (no, Im not touching the table or any other thing while with ultra cortex on). also... it did work somewhat yesterday and i dint change anything.
Any thoughts?

>>> EDIT: I just saw it did not add the image.. don't know how to add it..

The artifact domains are roughly 13-14Hz + ±25Hz & ± 48Hz. Any idea what they are? (I have the 50Hz notch on and those are not harmonics)

    Easiest way to add image is to upload to Google Drive.

    Look around your area for sources of electromagnetic interference, such as from wall wart power supplies, CFL or LED lamps, cell phones, towers, AC power lines, cords. Some conduits run inside walls and floors. Try running your test from another room. Etc.
