A quick project I knocked up. Apologies for the audio - might have been overdriving the camera. The sensor is a strobe trigger transformer from Jaycar (suggested by an article in Silicon Chip - there was a kit but apparently discontinued) Inspired by http://www.techlib.com/electronics/induction.html & https://goughlui.com/2014/10/04/project-audio-induction-loop-receiver-part-1/ |

Really interesting, guess hearing aid users must quickly learn to disable inductive pickup when on trains! How far away can you pick up overhead power distribution cables? |

Pretty much everywhere you go there's hum from power lines and in the street. Would be interesting to take it outside the suburbs. I think that proper hearing aids have AGC. Also I think my unit may have slightly excessive gain. |
