Personal brainwave biofeedback sessions seemed like a tantalizing idea too, when as a teen in the 2010s I was struck by it while researching neurology. I think it was a video of a long-time meditator who demonstrated total control of his brainwaves that really got my attention. Anyway, I happened to be in the Netherlands for a summer and ordered a mini OpenEEG PCB from it's designer from neighboring Germany. That's when I found out I had no idea how electronic circuits worked nor how to assemble SMD boards. I relegated it to a pipe dream after that, but have always been on the lookout for an easy to use device that could provide the same.
