Just happened upon this, whilst looking at a cartoon about arsenic based life forms. How are your moral rectifiers and magic smoke? http://xkcd.com/730/ Colin -- cdb, on 4/12/2010

I like the 666 timer.. bet it goes REALLY fast.. :-)

It's a start. I'd prefer something which was more complex and close enough to "real" that it took time and care to ensure that "you were having your leg pulled". Long ago in a prior lifetime we used to have circuits like that for cross-bar and early digital telephone exchanges - except that the people who provided them had no idea that they were sometimes a joke in progress. No names :-). (Fault driven modifications on cross-bar appear to be achieved by fixing the current problem and then waiting to see what would happen in due course). Russel

That reminds me of the old trick to play on people in purchasing: "Make sure you buy zero ohm resistors that are 1% tolerance for product X. 5% ones will not work in our design!"

But what if you need 150mW ones?

Unlike any other value resistor, zero ohm resistors are never their stated value. There's got to be one of life's big lessons in there :) Bob -- http://www.fastmail.fm - Access all of your messages and folders wherever you are
