Unpopular opinion: a $12 swap on my EEG setup at the Detroit meetup finally got my signal clean
I went to a small BCI meetup in Detroit last Saturday, maybe 30 people in a rented room above a pizza place. A guy in his 60s saw the noisy traces on my laptop and handed me a $12 tube of conductive paste to use instead of the dry gel I had been fighting with. I tested it that night and my alpha waves went from a messy blob to something I could actually read in about ten minutes. Six months of blaming my cheap headset, and it was the gel the whole time. What cheap fix did you all stumble on at a meetup or from some random person?
