Can I use more than one MyoWare with an OpenBCI board?

Hello everyone, 

I have recently bought some Myoware sensors. I have read the tutorial http://docs.openbci.com/Tutorials/15-MyoWare_Integration_Ganglion and I realized that for any MyoWare I need the power supply from the board. 
So, How can I used more than one MyoWare with only one OpenBCI board?!

Has anyone any clue on that?!

Best, 

Victoria.

    Victoria, good question.

    You can use the same header pin extension cables to make an adapter where more then one Myoware can share the power supply. This will require just splicing together some of the cables using a wire stripper and electrical tape to insulate the resulting joints.

    In other words, as an example, at the OpenBCI board at the GND socket: whereas previously you plugged the Myoware in directly. Now you will make a single male to multiple female "Y-cable". By joining one male and two or more females. The male plugs into the OpenBCI. The females accept the leads from the Myowares.

    Similarly for your + power lead.

    Hi again!

    Another question regarding two MyoWare connected to the Ganglion. 
    How should be connected each R cable to the board? I mean, since there is only one D_G pin, and I have two cables coming for the each of the ground electrodes, should I also make a Y cable (male- male to female) ? Would this not disturb the signal quality? 

    Thanks,
    Victoria
