I had no idea you could pick a radio wave out of the air without any external power that's super cool!

How cool, love that i found your channel

I love this video! I did the same thing as a child and I had a hard time getting it to work. I managed to find one build by somebody else and then I got some instructions from an experienced engineer and then I finally made it work. Did you know you can also light up an LED using the radio station's energy if you are close enough to the transmitter? I did that on my KZfaq channel. Check it out! 😁

Why is you trying to learn about the world you think you einstein or something?😂

Omg the fact that I also had the same thought. What if the world ends and need to reintroduce electricity. And then i realised i know nothing lmaooo

Cool.

Just say RLC circuitry short for reluctive inductive and capacitive that's how they were simplifying it back in my day

Oh no people get very sensitive about Einstein because of how much he did but people can be so defensive this way

After saving this for 4 days as watch later. It was a right decision

Came here from the AM radio video. Great video, I want that Mochi!

ONLY 3k SUBS, THIS IS AMAZING, YOU DESERVE WAY MORE

Nice work! This kind of video can bring some inspiration for young people. (I would love to show to my nephews, but they speak English...) Congrats for your work!

Wow I love your channel!

Please make this type of videos please 🥺🙏❤❤🎉

❤❤🎉🎉love your video and your funny explaination 😂🎉🎉

Very inspiring video! Makes me want to try and build something too.

You're very funny, and this was a great video! I really like your editing and choice of music throughout 👌 Not to mention, the content was interesting too

Random question…where did you get your shirt?

Thanks for an excellent video. Interesting seeing a crystal radio being built. Just of interest, my grand aunt (my grandfather's sister) was the first one in our family to have a radio, which was actually a crystal receiver, bought back in the 1920s. During the 1930s. my grandfather with a standard type valve radio of its day, connected to a long wire antenna throughout his house on one occasion, he managed to receive 3LO Melbourne from Sydney, which was quite an achievement back then and it even became an attraction to his entire neighbourhood. Following my grandfather, my dad continued with the radio interest, though he was also into SW radio. Receiving distant signals on radio has continued to be a fascination to me. I have also managed to receive long distance TV. Anyway, wishing you the very best. Rob.

Thanks for the video! : )

Very impressive.. good work.

You can easily improve your circuit by grabbing your signal from the top 10% of the coil. This will improve your frequency drift and selectivity, so you will hear less stations at once. To improve your circuit further you can start adding a transistor. And so on..Like someone else says it's a gigantic expensive rabbit hole.

You can contact the Aliens in space using your radio 🤣

im sad i can't become an engineering schizo rn and just develop these types of passion projects cuz im greedy

very good effort. the essence of engineering is persistence and incremental corrections of mistakes.

Lol your efforts, I really enjoyed the video

I have been feeling this lately too!

“I know nothing about anything,” is a good way to start a radio project. Honesty, I thought the smoke detector piezo buzzer would work but selecting the right headphone/earphone is critical to get the crystal radio to work. The headphone must be high impedance. This is why you don’t use the earbuds that come with the typical mobile entertainment device because they will not work in a crystal radio. They measure around 32 ohms. The reason why they don’t is too technical for this venue. The impedance of headphones for a properly working crystal radio should be 2000 ohms or greater. Crystal earphones are typically 20,000 ohms and this is why they were included in crystal radio kits.

So exciting! You are well on your way to getting an amateur radio license. Then you can also TRANSMIT and listen to your transmission. Then you can get into different bands, different modes and even talk to people all over the world. Then there are satellites... Thank you for this video.

It is really cool to see people get more interested in electronics. I have been teaching myself things for years and like how you threw yourself in the deep end. I can help you build a better radio that does not rely on resonance and tenable inductors to operate. Let me know if your interested in making a V2 and want help.

Thanks for doing this i've always wondered since i saw this project in a book of fun science projects for kids my mom had as a child

You should keep making videos about technical stuff

That resistor is actually making your speakers quieter since it's dissipating power you receive from your antenna. The coil and capacitor in parallel determine what radio frequency you are listening to. When you removed the capacitor and added the resistor, you ended up relying on the parasitic capacitances of the resistor leads and wires connected to your coil to "resonate" which tuned your radio to a dramatically higher frequency, but at the expense that what ever you received is probably dissipated by the resistor you put, depending on how you wired it since I can't make that part out from the video. All in all making a crystal radio blind like this, especially when making your own coil and capacitor is no small feat since you can't measure them, you can't know what frequency you are listening to, and you don't even know if there are any am frequencies in your area to start with

I am obsessed

Just a quick recommendation for anyone trying to replicate this, use an opamp (operational amplifier) it is very cheap and will allow you to "change the volume" of the received signal so you can hear it better on the speaker. so instead of putting the output of the resonance circuit directly into the speaker, you give it to the opamp and then the output of the opamp goes to the speaker.

Congratulations. Greetings from Portugal.

You were ahead of your time with this one. I'm at risk of sounding like a smart ass, but this is most likely a diffusion model. It's not really searching anything on the web, it has just been trained with tons of images and metadata on those images, and it starts with a random seed (that's why different runs with similar terms lead to different images, though some tools allow to use the same seed), and based on that seed it starts denoising progressively until it constructs something. Regardless, I think the exercise you do to reason if this is art or not is what really everyone should be doing.

Ger......who Marconi ? This Girl is a comedian it doesn't even know it ! But staying on topic, I'll say she is shocking ! 🤔.....?

" I have no Fucking idea " ! Well......yeah ! 🫲🥺🫴

Wait.....what happened to that spirally capacitor thingy ? LMAO.....! 🤣😂🤣

Perseverance is the real lesson of your video :) Does DE still have AM stations? That could make this a bit harder! But you were smart to go with the long wire antenna.

I find that mother song to be the scariest. The dissonance I think is scarier than other qualities you were mentioning in the other tracks. But I think the thing I find scariest in songs is when they are more linear rather than cyclical. Like that Paper Mario song was disorienting but it was constant and you can get used to it pretty quickly. But when a song is constantly changing I think that really adds to the horror.

What you doing video on making a generator

That's so cool! Congratulations on doing it!!!

The inductor and capacitor exploit a phenomenon called resonance. The energy captured by the antenna oscillates back and forth between the magnetic field of the inductor and the electric field of the capacitor. By adjusting their values you can set the rate at which this occurs to the carrier frequency of the station you wish to receive. The formula for resonance is f0 = 1 / (2 * π * sqrt(L * C)) where f0 is the resonant frequency in Hertz (cycles per second) L = inductance in Henries C = capacitance in Farads My guess is that your homemade capacitor did not have enough capacitance. It might have worked better to wind one layer of metal foil, then a layer of insulating material like black electrician's tape atop the foil, and then another layer of metal foil atop the tape. A problem is that all over the world broadcasters are switching off AM transmitters as they move to FM, satellite, and Internet for audio delivery.

There are definitely different types of crystal radios out there. Some are better than others. The biggest thing is have a good ground an having a good antenna (about 30 m, and as high into the air as you can get it). Even if just the one end is up in a tree, that will help. The resistor is needed if you are using a piezo electric earpiece. If you are using a high impedance head set (like the old style WWII headphones), than you can use a small capacitor instead.

Magic...all around us. If we had wizards they'd be working in cube-farms.

God. Next you build a transceiver 😁
