Oh yes, and Homer Simpson also “invented” it in the episode The Wizard of Evergreen Terrace. And it was Homer that one Gadget Master, Patrick Priebe, was emulating with his hand-crafted electric hammer.
Ben Coxworth, of Gizmag, describes the aluminium tool, which is powered by a 18.5-volt, 3,000-mAh lithium-polymer battery:
Depressing its wooden trigger activates an electromagnetic coil, which quickly draws in a cylindrical steel core. That core is attached to the bottom of a fiberglass rod, which shoots upwards as the core goes through the coil. Via a linkage, that rod subsequently thrusts the hammer’s hinged head down and forward in an arc. Once the trigger is released, a spring pulls the rod/core back down again.
