SHIELD-EKG-EMG
5.4 Custom electrode connection
To make the passive electrode yourself you need three cables, passive electrode surface and 
audio jack. The way the signals go for connecting the audio jack is shown below:
Note that connecting active electrode that way will probably lead to electrical shock for 
SHIELD-EKG-EMG. Only passive electrodes can be used with SHIELD-EKG-EMG.
