Zap Your Brain

I've seen this before with various claims attached ranging from a cure for depression to increasing your IQ. I suppose you could do it yourself by making a simple puleation circuit with 2 knobs, one for pulse width and one for intensity, 0-9VDC and embedding the rig in an innocuous sweatband.

Sure: Try different settings for a week each, and test yourself every Sunday by asking yourself if committing a heinous crime sounds like more fun than inventing anti-gravity.

I'm experimenting with motors, amp draws, and the like in the garage right now. All this without the benefit of an electronic headband. Just think how much fun this would be to pull the drain plug as you fly over the Antifa rallye.
