Hi folks
I'm new here, looks like you've got a wealth of info and people here
Okay now for my question. An example...
The FIRST circuit on this page:
http://uzzors2k.4hv.org/index.php?page=flybacktransformerdrivers
has a 12v rail and some 'ground' symbols. In this circuit, are all grounds going to the same 0v of the power supply??
The right-hand ground is the secondary coil of the transformer, is this ground really connected to the same ground as pin 1 of the 555?
I guess my bigger and more general question is what exactly is ground symbol if you've also got 0v reference in a circuit diagram? Is it different depending on whether you have 0v/9v from a battery for instance, or you're using a 3-pin mains AC plug and thus you have Earth ground as well?
Confused and sleepy,
JJ
