Power Supply and DAQ for v1.7

[Blake Hament]

I did not see specifics on power supply and DAQ for updated version 1.7, so I emailed Dr. Jonas Forsslund directly. For anyone else who is curious:

Power supply = 19.5 V 3.3A DC, most laptop chargers should work

DAQ cabling = 50 pin connector to the "Analog" port; 26 pin connector to "channel 0-2" port
