Electrode Problem and Raw Data for Commands

StemScholars2 · April 2019

Hi,

I am part of an undergraduate research course where we are attempting to fly a drone through use of your Mark IV Headset and ganglion board. We have a problem with one of our electrodes. We have a spiky unit attached to channel 1 (according to the openBCI GUI), also in Fp1. The readings from this are very low compared to our other electrodes. Another electrode was in channel two, and then the two remaining switch between channels 3 & 4 and then to channels 5 & 6: no problems in any of these channels or electrodes. We have tried switching between different electrodes and channel one always has a very low output (less than 10uVrms) while the rest fluctuate quite a lot. Is there any fix to this? Or is it typical for this channel to have very little fluctuation.

Also, we had very little luck with software, so we are trying to use the raw data from the lock files in order to give basic commands to the drones. We have already coded for the drone to do certain movements for numbers we get from the electrodes, but do you have any examples of others doing this?

Thanks in advance,

look at this picture-- do you see how the pin labeled +1 is one in from the first pin on the Ganglion?

Have you checked that the wires are not 1-off in location? If the wires are in the correct pin locations, have you tried swapping wires on the pins while the EEG runs, to see if it is the first pin or the wire on the first pin that is at fault?
