Electrical Experimenter (05:10) February 1918

Hugo Gernsback, editor

"In the early days of the war it frequently happened that the French farmers would run their plows into unexploded shells buried a few feet in the ground, with oftentimes fatal results. One of the French army engineers thought of a novel electrical scheme for accurately locating these buried shells, thousands of which had landed in the fertile fields along the one-time firing line." His idea involved the application of an extra large size Hughes' balance, an instrument well known to every electrician."
This is the February 1918 issue of Electrical Experimenter. The cover art and feature story is “A Gyro-Electric Destroyer” by Hugo Gernsback. Also included is a fictional piece “How Jimmy Saved the Troop Train,” articles about constructing a damped and undamped receptor and a Wheatstone bridge, and an early metal detector used to look for unexploded WWI artillery shells.
