Machina Electrica, the electricity generator:

A modern constellation created by the German astronomer Johann Ehlert Bode in 1800. The constellation was made in order to honor the creation of the first electricity generator. Machina Electrica is composed of dim stars that can be found south of Cetus, the sea-monster, between Fornax, the furnace (also called Apparatus Chemicus or Fornax Chemica) and Sculptor (also known as Apparatus Sculptoris). The constellation appeared in a few star atlases, but was never widely accepted and is no longer recognized by astronomers.
