A project log for ESP32 EEG

Heavily inspired by OpenBCI, especially their ganglion board design, but with an ESP32 handling communication/control

Tried a rudimentary algorithm for producing a motor control signal. This algorithm calculates the difference in alpha band power (seemingly 10-14 Hz for me) between left and right motor cortex. Hypothetically imagining moving my right hand should reduce alpha power in the left motor cortex, and vice versa for the left hand, and I should be able to control a 1-dimensional signal by taking the difference of those two metrics. I wasn't feeling like I had an ounce of control over the signal though and it's difficult to tell if I just need to train more or if I need a better algorithm (but almost definitely the latter).
