Could one of these devices be tweaked for audio? I like to listen to my neighbors do it and its difficult to keep my ear pressed up against the wall and "exercise" at the same time.
I do this with an AM radio sometimes. The sound you are hearing when you scan your cat sounds like LTE data noise. either from your phone or a nearby cell tower.
How sensitive is this thing? I made something similar but it’s just a pickup coil from one of those as seen on TV speakers where you just place your phone on top of it and it picks up the signal from your phone’s internal speaker.
If I hook my headphones to a small first act amp and hang the headphones on my ceiling fan I can faintly pick up a radio station.
Reminds me of the days when I could listen to the operation of the PCI bus on my Pentium Pro workstation and know what it was doing. This was a while ago, probably before you existed, but you could try it now with an arduino or similar MCU perhaps?
2:48 some high end gaming boards have Spread Spectrum on the Bios, that supposedly clips RFI Transients to FCC Regulation… "lowers RFI in high CPU loads."
There’s a lot of interesting things to find using a portable AM or SW radio. As for detecting cyborgs, it would depend on the type of cyborg – I don’t think it would work on Simone Giertz whose only "machine" part is an inert piece of metal. (A radar would work but it would also work to some degree with normal humans as well.)
Microwave is not a faraday cage really, it is a shielded cage, but the door itself is not electrically connected. The reason it does not leak is because it has a cavity trap at 2.4GHz in the edges of the door, the hollow under the plastic cover, that at 2.4GHz acts as an effective RF quarter wave reflector. At lower or higher frequencies it is no longer resonant and no longer acts as an attenuator, allowing Rf energy to pass through. As well the steel cavity walls are not too effective against magnetic fields, though they do attenuate them, and are very effective at 2.4GHZ where they are reflectors of the fields.
To turn a microwave into a faraday cage you need a heavy copper braid between the body and the door metal on the hinge side, well bonded at multiple points to the metal, and also a copper braid compressed between the door edges and the cavity to do the same, bare metal ( both the steel and the copper) contact along all the sides of the door.

I want to see inside that 13.5v 50a power supply of yours!!!

Needs more electromagnetic floppy disk music.
Xbox 1? More like Beatbox 1
found this on reddit, just wanted to say kudos for immediately satisfying the title – very considerate editing!
cooooooooooool!
the pretty lady is your GF? đ
How can I find a bug or camera in a hotel room or house I rent? -73- W1KPS

Ahh the sound of cancer
Excellent ! Must be a way to make an electro-theremin with that !

2:34 – It can also detect microwaves (LTE cell tower)
That is very cool (:
Put the computer charger and the xbox together to make a hit song!
The ceiling fan remote is the keyboard.
U should do a song with the Xbox. What a riot.
Oh man what some decent shielding wouldn’t do đ

You forgot the link to original video
Such great music đ never have I felt so touched
Iâve experienced this from putting my phone up to my guitar pickup with headphones, very cool stuff
Dude can we collaborate so I can turn this into a song?
I like listening to the secret Life of phones using my AM radio. Is it really asleep ? Nope it waits ages after the screen turns off sometimes.
Cool!
