Very awesome steampunk "Generator ". The "Generator" is functioning as a desk clock. I built the "Generator" using brass gears and cogs from old clocks., old radio vacuum tubes, pluming parts from Home Depot and miscellaneous parts found in my junk boxes. All the metal parts are soldered, bolted or riveted and for the glass parts I used jewelry grade glue. The clock is battery operated and can be accessed from the back.
