Jon mentioned "You don't have to do anything fancy, unless you're going to derive your DC supply from the 24 VAC transformer and have a common "ground" point between the AC and DC signals".  I don't understand this.  

I was indeed going to come from 120VAC to a irrigation wall wart (26vac) to the triacs.  Then sip power off of the 26vac through a wheatstone bridge (to convert to DC) then to the 7805 to drop it down to 5vdc.  

Hmmm.  Now that I say all of that, are they going to have different grounds?


I'm sooooo confused!  :-)
