I was going to reference Charles Cosimano in the Tesla post below, having first read about magnetic helmets in his writing, but after actually finding his website, I realized he needed a post all his own.
Ever wanted a Psionic Amplifying Helmet? Wanted to determine the amount of blue in a friend’s aura? Thanks to this site, you can now build your own psionic equipment using magnets and speaker wire and stuff. If anyone tries this stuff out, let me know how it works.
