Near Infrared Spectroscopy for Brain Computer Interfacing Make Part 6

In this part Chris speaks about the power supplies used and their settings. This is more a how-t0 for this particular set up and is taking the place of a manual for our system it seems. Chris speaks of the LED driver unit - this is an important piece of kit as obtaining a stable optical signal is contingent on driving the LEDs in a highly controlled fashion. The LED driver is driven from the other piece of National Instruments kit - NI-PXI6723. The number of wires appears to be exponentially increasing....yikes.
