Karsten: The nervous impuse along the neuron is an electrical phenomenon characterized by a Na - K eflux-influx and travels at a velocity of approximately 130 miles per hour. So you may do the simple ratio: one inch is to 130 miles as t is to 3600 seconds. Revise for mS or uS. Connect pin to a 0.01uF cap to zero volt return. It sounds like an interesting project. Have you considered stimulating the hypothalamus to see if you develop the "orgasmatron" effect? I don't know how you could verify its effectiveness or lack thereof. Perhaps some optical device to scan the eye for utopian expression. Some subjective element is perhaps necessary.
