Magnetometer

Some time ago, I mentioned on this blog that I was "whipping up" a magnetometer. It is published in this month's EPE magazine, the UK's no. 1 electronics magazine. It detects rate of change in a magnetic field, and will pick up the earth's magnetic field. What this means is that my magnetometer will report when something turns within the earth's magnetic field -- a car/automobile, for example -- or any of a thousand things one might rotate in order to steal them. OBSERVATION: The magazine deleted my suggestion that my circuit might prevent a husband from turning right or left.
