Well you were going to get a Pi anyway because you’ve been excited to learn more programming skills and continue your electronics engineering hobby. While not doing any soldering or programming today, you’ll be installing software and exploring it. Besides, if you already had the Pi, this can be cheaper than buying the Seesii spectrum analyzer [sic] that I bought (and that was the cheapest one they made).

Welcome to the first of a three-part rabbit hole. I’ve been reading a book on ‘paracoustics’, or sound and the paranormal, to see what people really think about aural experiences while ghost hunting. While a lot of that talks about vibrations of physical matter, such as infrasound, poltergeist ‘raps’, and telephone messages, it got me thinking about vibrations in electromagnetic fields.
