you can create a "floating ground" -- if you can't find a small transformer
with CT -- use a pair of resistors AND a pair of diodes -- you will also
probably find a discarded cell phone charger which fits the bill.

Looking for a source for small (150 MA, 300 MA or so)
center tapped transformers for 5 or 6 volts out, 115 volts in.
Thanks.
