How would you (practically) go about one of those?

Just found this here (FB ad): https://www.thomann.de/de/soma_ether.htm. I think it's a lovable idea - MANY years ago I did some "Micro Music" with a friend of mine with bended circuits and a few (very expensive) original electroacoustic gadgets. Fun! Now I'd like to try something like this in a broad spectrum. Is it doable?

Happy New Year by the way, masters of the electronic realm!!

SETI?

I don't quite get what this thing is supposed to do. Just receive and amplify all electromagnetic noise? I have a bunch of boxes that do that. I always considered them broken. Never occurred to me to go "oh, that you hear no signal but only weird noise that changes when someone turns on a light? That's  not a bug, that's a feature!" Essentially any coiled piece of wire with an amplifier attached will do that to some extend. If you want some control, I would take one or several AM radio tuners. Super simple:

With the frequency tuned right, that should pick up all sorts of electromagnetic garbage in the right environment.
