Atmospherics Monitor
Approx construction cost US$27
Tune in to the sounds of the heavens in turmoil! With the chaotic weather of recent years, have you given any thought to what’s going on up there? It is generally known that you can hear on a domestic radio the electrical activity of lightning when a storm is in progress, with the characteristic large crack and swishing sound, emanating from the speaker and that’s about all. What if you could hear other sounds over a distance of thousands of miles away, such as Inter Cloud Discharges, Sliding Whistles, Tweaks, Pings, Chirps, Risers, Chinks, Clicks, and the exotic Dawn Chorus? “Has this guy lost his marbles?” Well, no, because indeed you can detect and monitor all these sounds from our atmosphere, from the comfort of your home, using little more than a ferrite rod with a wideband amplifier, and piezoelectric sounder – as you can now discover with this project!
