fluorescent Bulbs

2006-04-04 by J

Hello,

Has anyone made a circuit that has something like some digital logic 
amd a pic with some long conductor paths that will drive a fluorescent 
bulb?  Currently I am isolating the AC signal by having an analog 
ground plane that is isolated from the digital ground plane.  There is 
a common ground area in which both planes are connected by a path that 
is at least .50 inches wide.  Has anyone done something similiar and 
how much noise did the bulb create?  Any ideas on how to keep the 
noise from traveling from the AC ground plane to the Digital ground 
plane via the common ground area?  Should I keep the pathway to the 
common ground area to a certain minimum? Any help is appreciated!  
THANKS!
