Seems to me we have some humourously challenged PIC Listers on here. I have to admit, I was a little unsure whether the original post was a spoof, but the rest of them were blatant. Operating toasters in reverse?? C'mon guys, anyone that subscibed to an emmbedded microcontroller list should have enough electrical knowledge to realise that this is a joke (even if some of them can't quite follow unsubscribing instructions :o) Whilst on (off) the topic, if any of you are hi fi fanatics, did you know that because the signals going to your loudspeakers are inherently AC, that you probably have the same electrons in the speaker cable that were there when you bought it? These old, worn out electrons can impair sound quality. Simply remove the cable and flush out the old electrons and inject new ones with a battery or bench psu. Oh yes, that was a joke by the way.
