Part three is here! We’ve explored spectral analysis on a vigil using a dedicated piece of portable kit; set up a Raspberry Pi; now we’re going to explore using a spectrum analyser on that Pi. Why? 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).

If you’ve used the Arduino from the previous posts, you’ll have no problems using a Raspberry Pi, which is much more like the computer you use everyday. I used one I had from a previous project, which is a Model 3B+. We’re currently looking at a model 5, but that is much more than you need right now. Use what you have or get what you can, but don’t stress too much if it is an old one. Mine looks like this:

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.
