Hi guys, It's very late here, and we have been officially slapped on the wrist for this thread, but I have just got to say that if I got a "ROTFL" out of Olin, then it must have been worth the bandwidth. I also have to say, his reply made me laugh too! I've never managed to get myself thrown out of a McDonalds! David Duffy's comments on roo meat seem to ring true to what seems to be the general public opinion. I can not offer my own opinion, as I have never tried it. But from what I do know, Roman must have got a tough piece - one that John West rejected perhaps? I also need to add that as clearly as I remember that roo meat scandal, I don't remember McDonalds being involved! :-) But my variation of this thread did start of quite serious though. My next project is a Triac based speed control for 240VAC and I do have to detect the zero crossing point of the AC wave. Before anyone suggests the obvious, I do not have a transformer. So far, I've got "2 resistors are better than 1" and Olin's "the more parts the merrier" :-) - then we just started getting silly. I will draw the circuit which I believe Roman's original comments were about and post it or a link to it on Monday. I've never posted a file to the list. Is there any maximum size, format, etiquette to obey? I should focus this question to Olin only - as he won't hold back with his opinion! :-) Any thoughts on why this technique should or should not work, is or is not safe and would or would not pass regulatory approvals will be interesting and most appreciated.
