Carbon rods used to be in the carbon-zinc batteries - in the days before all the current exotic ones. I've not seen any (nor have I looked) in years. (a reasonably decent size in the D cells)
As a child they were a source of zinc (and a little bit of hydrochloric acid to make hydrogen for exploding balloons) and carbon rods for (once only) arc lamps. (man did Dad yell when the breakers popped...)
Wall warts...don't know.

What kind of power supply current? Would a wall wart work?
Do you have any idea where to find a carbon rod in the US?
Thanks!
