Abstract: A timer is provided. The timer includes a rotatable electrically non-conducting ratchet gear, an electrically conducting pawl mechanism, and an electronic drive circuit. The ratchet gear has a plurality of teeth. The electrically conducting pawl mechanism includes a pawl configured to engage one of the plurality of teeth on the ratchet gear. The an electronic drive circuit is electrically coupled to the pawl mechanism. The electronic drive circuit passes a current through the pawl mechanism such that the pawl advances the ratchet gear by one tooth pitch.
