@jpmorgan187 Ya it was a mistake.. Look at 3:46 he says it your way...

At 1:00, he says "if the voltage across Cs drops below 1/4Vdd, then the output goes high". Ok, fine.
At 1:18 he says, "if the voltage across Cs rises above 2/3Vdd, the output will go low". What??? The voltage difference is negative, therefore the output is LOW, but then it gets inverted so it's HIGH.
Neither of those two equations makes sense either.

@Aev308
i think every object has capacitance, at least metals and stuff like that, keys, coins (money), etc....

im guessing this is the same way a touch screen phone works. but I don't understand how an object with no capacitance can unlock my phone and call some one when they are both in the same pants pocket
