Anyone know if the price of biofeedback equipment has come down to earth? I always had a bit of an interest but originally the devices were expensive medical equipment and later some commercial entities marketed their 'services' at what I think are uneconomic rates. Since the only costs are computers, sensors and software they should be just about free systems floating around by now; look things like Skype are free.
I meditate a bit and expect I could call up a theta wave pretty easily, just want to find out for myself. Years ago, in my science fiction days, I expected we would all be hooked up to the internet by now.
There is various gear on ebay but I do not know what is necessary for a working system. Any insights into these systems and their affordability.
