Thanks for the warning. Subbed btw ;)

Note: instead of a solenoid you could use the tape read head from a cassette player. Then it would be more sensitive.

I had the same idea and thryed it. but it didn't work. I think my tape read head is broken.

I absolutely don’t mean this in a negative way, but this channel has a 90’s DIY TV-show feel to it, honestly I kind of like it.

0:45 that penmanship.👍

You should build a long range mic. Something that you could hear someone from a couple hundred feet away

That's suspicious... Personally, I didn't think it was practical until I saw a use for it (at the end of the video with the guitar). A lot of these things may be fun because they occupy you.. ultimately though, what's important is how useful the things are. Unfortunately not many things on this channel are useful, merely fun. If you see this comment, please consider carefully planning and releasing videos that are practical for people; Devices which produce a speaker effect or w/e that effect was with the electric guitar would be great; Especially if it were cost effective over buying one. Stuff like that would seriously make this channel take off.

That is an amazing device, can already see the use of it. great job guys !

Finally another Keystone science video!!! I've been waiting for a new video since you started college!!!

I've learned so much from both your channels. Awesome job.

I did the same thing once but with no op amp i connected the coil to my headphones and it's not as loud but works surprisingly good.

Made it. Really cool circuit. Gonna go on an electromagnetic scavenger hunt tomorrow! :D

So glad to see another video!!!!

Brilliant. Thank you for sharing your knowledge.

Sounds cool! Good video!

This will allow you to hear different emf waves around you. Might be a great way to document v2k.

thanks definitely going to make this one.

Can I use it to detect ghosts assuming ghosts emit emf

Both of you are awesome

Now, how about adding an oscillator, a mixer, and converting ultrasonic sounds down to where we can hear them?

Omg. You and TannerTech in one Video? Like a dream

We used to put a Mimi FM radio next to Tandy Trs80 computer. You could hear a difference on which subroutine in a program running.

Great and informative video

Interesting project.. Nice work ...!!

Great project.

Oh, love your channel, I am a subscriber. Am learning a lot from your channel because I don't think you talk fast but make things look simple to make. Can you recommend a store for buying electronics like the bread board now that I was going to use Radio Shack, they closed!

Great vid! Have you tried ways of harvesting solar energy (complete project) ?

Awesome video! I'm going to build this..

You ever mess with the tempest software and a sdr dongle it can pick up the same electromagnetic sounds except the software can interpret the sound and decode a computer monitor so if you had sensitive enough equipment and someones pc wasn't in a Faraday cage you can see everything they do on screen. Even without the software there is a way to do this just in sdr sharp to decode some sounds displayed as images on the monitor.

Hi! Great video! Where can I add a potentiometer to control the volume of the speaker? It's pretty loud...

You sound like a genius....nice video

I was WAITING for you two to collaborate!

Good work boys

Can you use different amplifier chip like basic amplifier chip? And another question can the lm386 can be found in electronics like TVs and radios.

This is awesome!!! Thank You!!!

The guitar bit was really awesome

Frickin' cool.

Could you give me a detailed step by step on how to make this? I bought the supplies listed under the video. Thanks

Thank you, nice video.

I was doing some research on EMP’s trying to figure out if I could make one to either play a prank on a large group of people at once or come up with a magic trick that lots of people could participate in. Anyway I ran. Across this channel and it is awesome!!!!! Please keep it up

Can the circuit be modified to hear electromagnetic transients or noise in the atmosphere?

I tried your link to "Tanner Tech" and it says no content on that channel!!

You young guy are great!!! And brilliant also a bit corny especially at the end.....LOL Corny is an old term to say goofy funny which to me is wonderful so it's a compliment. Keep up the great videos!!!

very simple, yet very cool. I am interested in devices such as this, that is, those that allow humans to perceive the rest of the universe that lays hidden beyond our currently evolved senses. Additionally to hearing EMF's, I am very interested in SEEING them. Do you think you could tackle this human enhancement?

I read an article some time ago on Wired Science magazine where a guy had actually done this. He also wanted to see all the electronic transmissions in the air. So he developed a 2 D viewable image showing the different electronic waves in the air around him. I thought he did it in 3D and why I was interested in it so I didn't care to follow up on it. His PC screen just showed red lines, blue lines, color coded lines going across the screen. The thing I questioned was how he captured them to show them as lines all at once. Then I found out, he mapped them so they weren't a real time display.

A fox/hound cable tracer kit will give you similar capability if you don't want to/can't build anything.

Can you review the super mini bluetooth dongle v2.0 to make it music bluetooth reciever??? Can you do that???

Question associated to your project and only because one I'm not electronics savy and two I don't know what to call it but could you explain to me what causes that magnetic interference when you brought the solenoid and speaker too close to each other. I know the same thing happens when you bring two microphones close to each other. I know It has to do with magnetic waves but why are these waves making a noise? Next, why choose a solenoid from a washing machine?

Oooh TEMPEST stuffs!

Probably not because the audio is encoded/compressed for better bandwidth so you won't be able to hear the raw audio like you would with a radio or whatever.
