Brian does not mind. In fact I hope more useful stuff like this can be posted. Maybe something of it can be put into production and we'll all get rich. If that happens then I suggest our first capital expenditure to be the purchase of a corporate jet and our first shareholders meeting to be held on the beach in PhiPhi Thailand Kota Kinabalu Malaysia. Best beaches I've ever seen.
hey where are the smiley faces? Don't we have smiley faces on this BBS?

What about it Brian? Ever considered any power conditioning products?
