Build simple circuit (and code) using 3 axis magnetometer (preferably LSM303C) to look for frequency between 2-10Hz on all three axis with adjustable gain. When field is detected, trigger an LED which then stays on for 0.5 seconds after the field disappears. Circuit is to be small and powered from one LiIon 18650 must be suitably power frugal
