Modern RWR equipment however changes this up in a much better way. The signal processor checks to see the source's behavior to tell you if the contact has locked you or if something new has shown up. I like that they remain shrill beeps, though.

That ship's radar was really cool to hear the "blip" timed with the rotation. It's a little unsettling to know all this radiation is around us but it's nothing new, we're also constantly bombarded from space too.
maybe you're confusing "radiation" with "ionizing radiation", "radiation" is a broad term that includes the heat your radiator gives off. Cosmic radiation is ionizing, but radiation from RADAR/radio/WiFi/BT/mobile data aren't ionizing, they won't cause you any harm.
@@uncreativename5736 I'm aware not all radiation is the same and not all of it is dangerous. The unsettling part of my comment had to do with our inability to see most of it. Visible light is a pretty narrow slice of the electromagnetic spectrum. But you're right, I was using radiation in general not limiting to ionizing radiation. I'd be lying if I could remember the difference without first looking it up.
@@uncreativename5736 There is also plenty of non-ionizing cosmic radiation. What do you think the field of radio astronomy deals with? The most famous example is probably the cosmic microwave background but really almost every active object is space emits some radio waves too. The image of the supermassive black hole in the M87 galaxy was also captured using radio waves. (And technically, even visible light from stars is a form of non-ionizing electromagnetic radiation.)
Oh man, this gives me flashbacks to when cell phones were just becoming common. Every day I'd find some new device (in one case a whole intercom system's worth of speakers) emitting the dreaded GSM beep. I don't encounter it so much nowadays, and I wonder how much of that's down to better shielding versus different frequencies being used.
I quite like that sound, so sometimes I listen to Mario Piu - Communication. At the time I was so impressed someone actually sampled it to make a dance track, but at the same time it was annoying.
I recently pulled out my old Nokia 3390 and popped a sim in it. My modern Corsair usb headset picks up the interference, but you have to hold the phone very close to them. I should try it out on some more things before 2G gets shut down at the end of 2022.
I had an old Yamaha PSR-170 keyboard that did this. I'd always set my smartphone on the music stand when I was practicing, and the first time I heard the sound was when I got a call, and the buzzing startled me so much I smacked the phone off of the music stand onto the floor and shrieked like it was some kind of bug.

Reminds me of when I was a kid and cell phones were in the flip phone razor era. I believe it was 2007. Every single time before I got a call or a text, a TV at my grandmas house would receive a little static noise. So I knew to grab my phone like 3-4 seconds before it even rang :p
I found out while looking into controlling those wireless remotes via pc/microcontroller that one of the ways you can do it is to output that 'sound' the remote makes directly into audacity and analyze the waveform to get the actual binary data from it, so your controller can send out an identical signal. dont quote me on this, but it's something roughly like that. thought that was very cool
@@experimentalcyborgcaptured here are electric field disruptions at low frequencies caused by a varying strength in the signal, which is why you can't decode GSM just from the phone interference sound, as it is merely a square wave caused by the phone transmitter turning on and off rapidly This is also why it's so easy to pick up AM radio with a bunch of unusual stuff when you're close to a transmitter

Fun Fact! No your car cannot be hacked even if someone were able to reconstruct what the key fob was sending from the audio.

The first wave of remote car unlockers were, and obviously it was used to steal cars.
@@daanhoek1818 with enough expertise almost anything can be hacked. Newer car remotes use rolling codes which means you can't replay the same code again. One exploit involves jamming the unlock signal and capturing it for use later. It's known as a rolljam attack.
I saw a vid of a couple guys steal a Rolls-Royce by using a big antenna to pick up the signal from the key fob and amplifying it to trick the car into thinking the fob was there
Car remotes started being based on rolling codes before the _1980s_ were over. You can get databases of the codes in use, covertly find out what the remote sends, and send later codes in the sequence at a later time; perhaps the next day. I haven't exactly made a study of this, but the rolljam attack sounds effective if you haven't got a database. Both work because the car must respond to a range of codes in case of missed signals.

A friend of mine bought his kid a child keyboard recently. I thought that was much worse than the keyboard which I had when I was a child and I didn't think I could find that model. Today I subscribed to your channel and here it is the exact model on my homepage.
Microphone cables would do that really bad, as they are nice long antennas for RF. That's why XLR cables are both shielded and balanced, so no interference occurs and you can even run the cable right next to electrical equipment with no issue
This was so fascinating. Not only for the keyboard Easter egg, but actually hearing the various electronic communication patterns audiated gives a whole new level of intuition about their functioning Are there devices that do this kind of transformation of EMF into sound on purpose? It seems useful for diagnostics as well as pedagogy
@@PosyMusic Wow, thanks for the quick reply! I discovered your channel the other day and I'm in love with your style. Thanks for your brilliant work 🙏🙏
What you feel on GSM phones is the frequency of the repetition of the frame. Because your phone was just transmitting 1/8 of the full frame, and the frame duration period was the period of a wave from audible spectrum.
Oh what good memories you brought me back, there was a time in which you could now when someone in your house revived a call because cassette playing radios and piano keyboards would start making a weird beep like noise constantley
The Casio VL-Tone has an FM like noise floor. I've made a Radiation detector from a regular car relay coil since it has around 200 ohm impedance. It makes it suitable to be directly connected to a dynamic mic input.
Reminds me of when I got ahold of a set of old walky talkies and a boombox from my grandparents when I was like 12 or something like that. I realized that if I put the walky talkie in a certain place on the boombox, and tuned the boombox to a certain frequency, the sound from the walky talkie would also come out of the boombox.
im just too young to have experienced the sound from old cell phones or radio shows, however i am intimately familiar with that exact sound because the devs for GTA IV made sure to play it every time you go through a tunnel lol
You've just gave me idea of using wire detector as external oscillator for my monosynth. I don't even need any modifications as it already has headphone output.
Really looks and sounds like an EMF detector ... I mean it wasn't meant to be one but the circuit for an EMF is literally this XD. I think you get this when you try to amplify an analog audio signal that was not properly shielded, it amplifies the audio you give him AND the electric signal made by random electromagnetic waves passing near you conductor.
Some of the "radiation" he detected was actually 60 hz magnetic fields. When he said that the radiation has been here since ever he was lying. Not8ce how the noise the bulb made was only auidable at close distance, unlike the wifi which were at long distances. This means that the bulb produces only minimal microwaves, what he was really detecting there was the magnetic field. This microwave radiation from wifi is not safe, it is absolutely unnatural and unnecessary for the body, avoid it.
@@mattbanks3517 You need a lot of microwave to damage your body in a meaningfull way. Light and radio signals are all the same things : photons, electromagnetic particles. The only difference is the wavelength they have. Microwave is a relatively high wavelength (low energy) compared to visible light for example. Harmful waves of light start at the UV light (after the visible spectrum), it's the beginning of ionizing radiation and ends with gamma rays that are very harmful. Only ionizing radiation carries enough energy to damage living tissue and DNA. Otherwise you need to use pure body absorption as heat (so you need a lot more power, over the 100W) to impact someones life. Most microwaves used by phones and stuff use amounts of power that are insignificant enough to not impact our bodies. So as long as you do not expose yourself to a microwave oven (generally over 500 W), you'll be fine.
I loved the shot of you using it like a metal detector haha! I hadn't previously thought about incandescent bulbs making radio but it makes sense, that's the kind-of funniness of radio antennas: stick some wires and make them cover an area and now you're detecting radio (or making it)
I've had a few guitar amps over the years that would pick up cell phone signals if the phone was set on them or even full on radio signals on some of the cheaper/less shielded ones
Basically, what's happening is that parts of the audio circuitry in these keyboards is acting like a high-impedance antenna, picking up the electromagnetic radiation in the air, and the audio amplifier in the keyboard is amplifying the signal so you hear it coming through the built in speaker.
Aw man I remember when I was a kid I would play on my old yamaha in my room, and I would set my phone on it. When I got a text the keyboard speakers would buzz like crazy
Since nobody else is going to say it, I will. Nice thumbnail. The only reason I clicked on this video is because the thumbnail looked like a VR game or something.
The repeating click from the WiFi is probably the DTIM beacon, it is sent by default 10 times per second

Is this beacon associated with the Broadcast SSID setting found on some APs?

I hadn't previously thought about incandescent bulbs making radio but it makes sense, that's the kind-of funniness of radio antennas: stick some wires and make them cover an area and now you're detecting radio (or making it)
4:03 holy shit I had this exact keyboard back in my childhood! What nostalgia from a random video :D
I have to use a toner probe at work sometimes and I love doing stuff like this with it
Gosh, this just makes me wanna listen to more electronic music.
If it sounds like that near a microwave, just imagine what it must sound like near the Chernobyl plant..
i forgot how cool radio static is thanks for reminding me
It would be cool to see a video about how exactly you compose music. The tools and methods you use in making a song. Great stuff!
I know you posted the mouse pointer history a long time ago, but I just saw it and I really like the cursor you made. I'm using it right now,.
I've had a few guitar amps over the years that would pick up cell phone signals if the phone was set on them or even full on radio signals on some of the cheaper/less shielded ones
It works near the pickups too. Sometimes I would play a song over my bass pickups, after a ringtone accidentally got amplified during band practice.
Ah yes every audio engineers/musicians nightmare lol
I experienced a similar thing when i put my phone near a walkman. Apparently cellular signals from my phone are much louder than wifi
I guess you could say those keyboards are rad
very cool video looks like the subs coming in possibly
very COOL!!
This would be a cool sample pack.
Woah, so THAT's why my speakers made that bup-bidy-bup noise just before I get a phone call.
There are some really cool samples to be had here I'm surprised there wasn't some remix in the background of the video
leuk om te zien dat nederlanders ook goede content kunnen maken!
It’s always fun when your keyboard is an accidental antena
My electric piano does that. Try sending the output through a reverb effect.
yall laughing at chuck mcgill while he's living two centuries ahead of us
I hope it has an audio output. You can make some crazy music with it.
Nice.
Well done!
Danku ;)
@@PosyMusic Graag gedaan ;-)
this is so cool
Basically, what's happening is that parts of the audio circuitry in these keyboards is acting like a high-impedance antenna, picking up the electromagnetic radiation in the air, and the audio amplifier in the keyboard is amplifying the signal so you hear it coming through the built in speaker.
the microwave part could make good use for a dubstep bass/growl tbh
Very interesting
I highly recommend the book invisible rainbow for more on this
No way !
I have the gt 530 too, and I never understood why is was making some werid noises sometimes.
That definitely explains why now.
I went and tried this rn with my cheap keyboard and microwave made it make sounds. Neat
Aw man I remember when I was a kid I would play on my old yamaha in my room, and I would set my phone on it. When I got a text the keyboard speakers would buzz like crazy
I was thinking about if the keyboard was based on vacuum tubes and picked up radioactivity, but this is just an unshielded amplifier
Since nobody else is going to say it, I will. Nice thumbnail. The only reason I clicked on this video is because the thumbnail looked like a VR game or something.
"A bunch of baby ducks, send 'em to the moon!
Soda machine that doesn't work, send 'em to the moon!"
I happened to have a guitar amp that would pick up local radio when turned on. Likely some unshielded cable
Sounds like the sounds the ATG would make any time it was raining or if you put your phone by it, you could even hear texts
Why did the stupid UA-cam algorithm wait two years to show this? Amazing channel, thanks for the great content, keep going!
everyone: wow cool keyboard go detector mode
me: AYO this guy has a wacom cth-480
...which you could probably get an interesting signal from.
That modem set up gave me a heart ache
"This is a radar from an Iraqi SA-2 complex" *scratchy continuous tone begins*
Posy owns an Alfa... niiiice :D
Who else thought it had a built-in Geiger counter and was really worried for a sec there
love your videos! so what's inside? i'm guessing a big wire loop, but i don't know for what reason
Gotta make music with this.
The ship radar shot was money
That RF remote sounds awesome. Lmao it's space invaders.
