He went to the dump where his friend worked and over the next few months collected all the materials needed. Not long after that he had more free electricity than he knew what to do with. I believe he may very well have built the world's largest crystal radio. He ran all his house lights, refrigerator, fan and Tv from all the juice he got. Over the years they have upgraded the transmitter several times. I believe the current output is 250kw which I think is ten times the one they originally put out.

DUDE......awesome coil winding job......I wanna see the video of you winding the coil.....damn classy lookin' homebrew crystal radio....geez......excellent.....
Excellent video. Just a point of modern radio: It is NOT necessary to connect one side of a crystal radio (or any radio) to actual earth ground. Earth is an especially poor conductor of radio frequencies. Better to use a balanced antenna like a dipole or simply another piece of wire of any convenient length in combination with a long wire. Happy listening. b.
3:32 ... I remember the crystal radio in my Cub Scout Handbook in the '60's used a quartz crystal with a bent safety pin to search for the "sweet spots"... never got that to work
Question Crystal am radio, now they have plans for a "Crystal" FM radio. They also have plans to use a Crystal radio combined with a jewel their to light LEDs. Why can't you make a "Crystal radio" tv?
For those wanting to build an "crystal radio" a few points that help. 1) If you move the diode to a tap that puts fewer turns between it at the ground end of the coil, the radio is more selective but not as loud. This is good in a place with many strong stations. 2) An "antenna coupling coil" slid inside the main coil can help you to adjust the coupling to the antenna. Looser coupling (sliding the coil out) makes it more selective. 3) A wire making a full turn around the outside of the house can result in an antenna with two ends. A turning capacitor between the ends can make the stations louder when correctly adjusted. 4) 1N914 or 1N4148 work OK as a "crystal" if that is all you can get. A small signal schottky is better. 5) "stolen power" radios are a cool trick. You basically make two crystal radios. One is tuned to a strong station and makes the power supply for a simple one stage amplifier on the other. 6) You can often get short bits of plastic plumbing pipe for nearly nothing. 4 inch AKA 10CM diameter worked very well for me. 7) Take a magnet to the hardware store so you can check that any brass screws you buy really are brass. Brass can be soldered to.
perhaps you should have several crystal coil sets in parallel to an led that will provide better amperage...and then if you get 4vdc rectified to charge a decent 18650 battery with good amp storage capacity
@@fidelcatsro6948 The experiment is not really worth doing. If you run two crystal sets too close to each other, the antennas end up sucking up each other's signal.
I started electronics in the digital domain, yet I find the analogue domain a lot more fascinating. Your build quality is awesome. No 3D printed malarky, just sold structures that will last a lifetime. Subbed! Would you happen to know how a bass sound is generated in something like a TR808? I'd love to see a project on that.
I saw the title of this video and it reminded me that it could only be 'free'-energy as long as there are stations on the air to supply the crystal set with energy. Did you ever talk with or listen to Art Bell W6OBB (now Silent Key RIP) back when he would talk about his huge loop antenna he had going around his Pahrump Nevada property? I remember him talking about how he had to install a protection-circuit of some kind between that loop antenna and his rig, otherwise the rig would be damaged by large voltages that were being induced into that giant loop. I do remember that he said that he ascertained that those voltages were not being picked up from local power-lines or other man-made sources. The discussion went on for quite a few Coast-To-Coast-AM episodes, but I don't remember what he finally concluded.. I missed that episode. I believe that the voltages were being generated by the naturally-surrounding Earth's magnetic fields cutting through the loop and developing voltages across it and appearing at the two terminals of the open-wire feedline connected to the loop. Now THAT'S free energy. He had three turns of thick antenna wire looped along the top of 70 foot tall masts spaced all around his big Pahrump property. I think it was about 3,000-something feet of wire he used in making that loop. On the ham bands his signal always BLASTED in 5/9+infinity in my receiver here on the west coast when he used that loop. :-)
Love this. I remember trying to build one of these using old wire from a transformer the wire was just too beat up so I gave up. I think I may try again but buy new wire this time. I want to build this exact radio. I just got the book. I wanted a paperback but they want a wopping 400 something for the copy currently on Amazon. So I had to get the lame but informative digital copy. I never knew there was a way to make one this advanced I thought tge blued razor blad version was cool but this things out of this world. I built a modern radio some time ago from a soldering project kit and also a transmitter among many othere little 5 dallor soldering kits. I plugged my phone into the transmitter and high jacked a station to pick up on my radio. It was Purdy fun. Ide love to build a bunch of these fancy little foxhole crystal radios.
Nice, I love your presentation too...! I have been using it 30 years, but recently I added a transistor to amplify the sound. The landscape has changed so much..! There is constant buzz of cars, microwave, freezes, pumps, AC and what not. With my 200 ft long Antenna and speakers from old telephones works just fine. Asking you question ... Do my old Arial affects the tunning coil of One transistor set or not. The old set and amplifier set are a 2-3 ft Apart. God, I managed tune it finally after watching your video. Cheers.. Keep posting..!
May I ask what is connected to the stator on c2 in your build here. I was playing around with the wiring on mine and decided to connect the ground to the stator of c2 instead of to the frame of c2 and had interesting results it seems better than before with more channels when I had the ground only connected to the frame of my c2 with nothing connected to the stators and it worked but the ground capasitor seemed to have little to no affect to the output of the radio. I guess I'm wondering if I wired c2 incorrectly originally following the books instructions that said very little about c2 other than to wire the frame to c1 and to a headphone connection and to the 8 or 9th tab on the switch also wiring the stators together only on c2 if double gang. I was just going over your video again and realized you do indeed have something wired to the stator of c2 and started testing things on mine now I'm a little confused as to whether my new wiring is correct or not.
Hi. To anyone who needs germanium diodes, it is possible to find them in 90s digital telephones, you just have to test all diodes because they look similar to the silicon ones. Greetings from Peru
I Have A Question, 1:55 HOW Would You Know Where to Tapp In The Wires ? Like, HOW? With Some Kind Of VNA Or ??? I Just Don`t Grasp That, Maybe Someone Can Help Me With That?
Yes my visitors are amazed. By the fact that radio stations fight to get in. And guarded is my Baldwin head set. And a salvaged tank head set. Ps I do on ocasion use a couple low volt led to make a verry small lamp. Shutting off my room light. I see the room light up. As my vision corrects. And almost see well enoufgh to make notes. Or tune another set good show om 73de kv4li
I am more than a bit bewildered by the circuit. Take that coil switch. Position One (Left hand) A small amount of inductance (a few turns) is connected across the tuning cap forming a parallel tuned circuit and cannot possibly resonate in the AM band..also known as Medium Wave. Any signal which might survive has now got the rest of the coil acting like an RF choke in its path to get to the anode of the germanium diode. As the switch is moved to the right, more and more inductance is placed across the tuning cap and at the middle, only 40 turns worth can be tuned which won't make the Medium wave. When the switch reaches the right hand contact... the diode is now grounded on its anode and there there is nothing to detect/rectify. One simple question..AM I MISSING SOMETHING? I look forward to your help, (is it) John? Thank You. The redeeming factor is that the goldurned thing works!
I like the concept of that little radio of yours. I could make a wooden casing for it to look like a sort of a victorian era wireless. Where could I find a wiring diagram for this type of radio? And how should I decide the positions of the taps on the winding? Lovely series by the way. I also have countless old radios in my room, in the dinner, in the garage, all of them have tubes, and all of them are working.Additionally I have an oscillo-synchroscope, two old tape recorders, four turntables and a still working old ring ring sort of telephone with the huge dial. I have even managed to find a 16mm movie projector, perhaps from the 60's, and it also has 4 tubes for the amplifier, and a big one as a rectifier. In the olden days everything were just better. "Simplicity is the ultimate sophistication." as we know.. So long Sir!
Hi Istvan, I recommend that you get the book I talk about in the video: Radios That Work For Free by K.E. Edwards. It has the diagram and parts list for this radio. If you are inexperienced with radio building, you will find a lot of necessary information. Find the book on Ebay or at Amazon. Good luck!
Many thanks, I have alredy looked after it. I am also building a small Stirling power unit, much like the Philips mc1000 Generator. I'm afraid I got obsessed by some sort of a worldwide catastrophe, so I keep gathering tools drawings and information how to build equipment for such an event, as after it, there may not be working internet or computers, and only old analogue stuff would work. I even have many plans printed.. Strange I know, but in such a situation I will be utterly happy :D
The video was great. The only remark I have on safety. If you have 100 feet of wire up high it can attract lightning it might be a good idea to have a lightning arrester on the pole outside. So the lightning doesn’t come inside. 🤦♂️
hey, I plan to build an demodulator/amplifier using a NE555P chip by attaching the coil wiper to the threshold and trigger comparators and then the antenna has a connection to the control voltage pin I think this is a high impedance transistor that can act as a diode inside the actual semiconductor.
Mr Dillan made an excellent job. We just adopted a black and white cat similar to yours...her name is Lana Viveka. On the radio side my son built a couple of Crystal Radio examples for his science fair and worked fine except that the place was too noisy for the judges to hear well but my son did well. Thanks for the explanation. Love your videos except for the spiritual world one on which I disagree completely. 73, YS1RS.
@squarewave2 Hello sir, I love this build. I had a couple questions, I know this build is an older one of yours but I was wondering if this radio would be benefitted by adding a antenna coil or does having the looped coil make that a pointless addition? Thank you for your time. My assumption is that yes it will anhance its performance. Also I see the wrapped antenna on the cover of the book you have there. My question is in regards to it's practicality. Would somthing like that work effectively or is it better to simply run your antenna wire covering as much distance as possible as high as possible as you've stated. Again my assumption is that it probably does "work" but not nearly as good as the standard layout. Again thank you for your time.
Hi Bran Man, This circuit does not need an antenna coupler. Rather than trying to add one, you should just start with another circuit. The big loop antenna on the cover is fun to play with because it is directional; but depending on its length, a long wire antenna will do better. Thanks for your comment.
@@squarewave2 thanks for the reply. after some reading I came to the conclusion that it didn't need the coupler I got the book it's awesome. I bought two variable capasitors 365pF and a Alpha 1 pole 9 position band switch I looks to be the one you used as well actually. Now I just need to go get my 20 gauge enameled wire the head phone terminals the diode and all the rest of the bits and bobs lol I'm super excited to build it. What other bits do you got here that's not in the original parts list in the kit. Are you using the normal terminals for the antenna and ground connections? The coil might be a little bit of a challenge but I think I can get it done. Also what gauge wires are you using for your connections looks like maybe 20 0r 18 gauge. Also what gauge wire do recommend for the antenna and ground. shoukd it be solid copper wire without a insulator?
@@branman3336 Hi Bran Man, Any terminal is OK for the antenna and ground connections. Use any gauge insulated hook-up wire for connecting the parts. Making the coil taps is tricky, see my video "Make crystal radio coil taps". The antenna wire is stranded for flexibility not solid. It can be either insulated or bare it doesn't matter.Gauge doesn't matter either but heavier wire will be more durable. Good luck with your project!
Hi Bran Man The capacitor across the phones is really optional. It is supposed to fill in the gaps of the radio carrier wave but I doubt that you can hear any difference. But if you want one, use a .002 mfd at any low voltage value.
Your video brings me over 60 years back when I made my first crystal radio. I new nothing about impedance so the 75 ohm headphone worked perfectly. Now I am going to build another crystal radio together with my grandson. Unfortunately, there is no more am transmitting stations where I live so the result can frustrating.
Hey man if there are no AM radio stations try making one with a AM radio transmitter. There’s an easy one you can make with a 555 timer or you could go for an LC circuit transmitter or there are also microcontroller AM transmitters. Anyway good luck with the crystal radio!
I remember building one of these from shoe leather and buttons off dead enemy soldiers. I was in the trenches in Japan fighting off the Nazi invasion. I'd listen in late at night watch to Nagasaki Soki. That's about the time I met that French gal Simonie. Man at the gams on her. (falls asleep and begins a drop mouth snore.)
Both remarkable but only the radio is real. Nobody leaves our enclosed realm (Genesis 1:6-8). Thanks for the video. Excited to make something so awesome.
Very nicely made. I also made one using a galena crystal and they are tricky. The box says 1924, price 2/6 and says it contains 2, 3 or 4 crystals, a special contact wire and instruction pamphlet. Was I robbed? I paid £3 for one crystal in the tin box. I remember reading somewhere the wire was phosphor bronze. Bill, G4GHB.
Just picked up the book, there are a number of them available for a reasonable price on amazon. Looking forward to seeing how you're winding your coils.
Actually... I've got a roll of 45 AWG copper wire, thinner than a human hair; I've always wondered what would happen if you put that on one end of a Mylar balloon and use it as an antenna. Wind currents mean that it's unlikely to be a truly straight wire antenna, but it could probably get pretty high.
About 80 years ago my grandfather moved next door to a radio station that had around 50kw antenna. He built a giant array of crystal radio sets and wired them together and it provided him with free electricity that resulted in a greatly reduced electric bill. But I didn't really believe him. Two years ago I moved into a new place and directly across from me is an A.M. radio station and it's very big antenna. I am less than 100 feet from the base of that antenna. So out of curiosity I built one crystal radio (I made one as a kid decades ago) and included an LED in the circuit to see what happened. Well dang if it didn't light up. As it happens I bought a few miles of copper wire a few decades ago at a yard sale for less than 1% of the normal price, actually a fraction of the scrap metal value. Being the pack rat that I am I brought it with me when I moved. So... I got me a little power plant and since I've recently converted to all LED light bulbs I now have a very bright house and yard and pay 0 for the light bill. It's not enough to run the A.C. or other appliances but it takes care of about 10% of my electric bill and honestly the only thing I had to buy was the crystals, a small investment for what I get. I figure I'm saving about $180 a year in electric costs and I think I spent maybe $30 on the crystals at the flea market. Of course winding all those coils took weeks lol. My neighbors think I'm crazy with all the antennas under my soffits. A funny side affect though is that even without any speakers my whole house reverberates with the radio broadcast. At least the programming is pleasant.
There is no such thing as "free energy"; and there is not enough "energy" in the received radio signal to do any real work. If you could "scale it up", the energy would still not be "free". It took power derived from a coal or hydroelectric plant to power the transmitter. The answer to my title "free energy source?" is NO.
you could light up leds i think...Thomas Henry Morray was obsessed with crystal radios as a child, he supposedly invented a free energy device that lit up kilowatts of bulbs...of course it all happened in the 1930s if it was all true as reported

Yes and the term is not definitive. Earth Batteries describes either magnesium primary cell batteries or a type of polarized capacitor that can act as a primary cell battery depending on circuit conditions. Neither is truly "Rechargeable", but either can be accessible sources of electricity if someone is in an emergency situation. In a non-emergency situation, they can be quite costly. A primary cell eats the cathode, usually leaving a salt after it's been exhausted. The best 'earth batteries' are setup to be refreshed from time to time, but many of the "Free energy" designs assume that the electrochemical reaction is inexhaustible, and thus don't make allowances for it. Mr. Teslonian here on RUclips did some stuff with earth batteries a few years back that i watched quite carefully. it was interesting, but it's not the answer.

2) An "antenna coupling coil" slid inside the main coil can help you to adjust the coupling to the antenna. Looser coupling (sliding the coil out) makes it more selective.
3) A wire making a full turn around the outside of the house can result in an antenna with two ends. A turning capacitor between the ends can make the stations louder when correctly adjusted.
4) 1N914 or 1N4148 work OK as a "crystal" if that is all you can get. A small signal schottky is better.
5) "stolen power" radios are a cool trick. You basically make two crystal radios. One is tuned to a strong station and makes the power supply for a simple one stage amplifier on the other.
6) You can often get short bits of plastic plumbing pipe for nearly nothing. 4 inch AKA 10CM diameter worked very well for me.
7) Take a magnet to the hardware store so you can check that any brass screws you buy really are brass. Brass can be soldered to.
have.you lit up leds with those radios?
@@fidelcatsro6948
"Lit up" is far too strong of a term. In an extremely dark room "detectable" light is what I managed.
perhaps you should have several crystal coil sets in parallel to an led that will provide better amperage...and then if you get 4vdc rectified to charge a decent 18650 battery with good amp storage capacity
@@fidelcatsro6948
The experiment is not really worth doing. If you run two crystal sets too close to each other, the antennas end up sucking up each other's signal.
@@kensmith5694 ok..;)
I started electronics in the digital domain, yet I find the analogue domain a lot more fascinating. Your build quality is awesome. No 3D printed malarky, just sold structures that will last a lifetime. Subbed! Would you happen to know how a bass sound is generated in something like a TR808? I'd love to see a project on that.
I saw the title of this video and it reminded me that it could only be 'free'-energy as long as there are stations on the air to supply the crystal set with energy.
Did you ever talk with or listen to Art Bell W6OBB (now Silent Key RIP) back when he would talk about his huge loop antenna he had going around his Pahrump Nevada property? I remember him talking about how he had to install a protection-circuit of some kind between that loop antenna and his rig, otherwise the rig would be damaged by large voltages that were being induced into that giant loop. I do remember that he said that he ascertained that those voltages were not being picked up from local power-lines or other man-made sources. The discussion went on for quite a few Coast-To-Coast-AM episodes, but I don't remember what he finally concluded.. I missed that episode. I believe that the voltages were being generated by the naturally-surrounding Earth's magnetic fields cutting through the loop and developing voltages across it and appearing at the two terminals of the open-wire feedline connected to the loop. Now THAT'S free energy. He had three turns of thick antenna wire looped along the top of 70 foot tall masts spaced all around his big Pahrump property. I think it was about 3,000-something feet of wire he used in making that loop. On the ham bands his signal always BLASTED in 5/9+infinity in my receiver here on the west coast when he used that loop. :-)
Man , He solved the FREE ENERGY riddle !!!
Plz explain further
Love this. I remember trying to build one of these using old wire from a transformer the wire was just too beat up so I gave up. I think I may try again but buy new wire this time. I want to build this exact radio. I just got the book. I wanted a paperback but they want a wopping 400 something for the copy currently on Amazon. So I had to get the lame but informative digital copy. I never knew there was a way to make one this advanced I thought tge blued razor blad version was cool but this things out of this world. I built a modern radio some time ago from a soldering project kit and also a transmitter among many othere little 5 dallor soldering kits. I plugged my phone into the transmitter and high jacked a station to pick up on my radio. It was Purdy fun. Ide love to build a bunch of these fancy little foxhole crystal radios.
Getting energy from frequencies in surrounding area, works better if you add your own field to it.
The question I would like to know is which radio station was first heard on a crystal radio?
Nice, I love your presentation too...! I have been using it 30 years, but recently I added a transistor to amplify the sound. The landscape has changed so much..! There is constant buzz of cars, microwave, freezes, pumps, AC and what not. With my 200 ft long Antenna and speakers from old telephones works just fine. Asking you question ... Do my old Arial affects the tunning coil of One transistor set or not. The old set and amplifier set are a 2-3 ft Apart. God, I managed tune it finally after watching your video. Cheers.. Keep posting..!
What an excellent video! The ending was brilliant!
Came for the radio. Stayed for the cat
May I ask what is connected to the stator on c2 in your build here. I was playing around with the wiring on mine and decided to connect the ground to the stator of c2 instead of to the frame of c2 and had interesting results it seems better than before with more channels when I had the ground only connected to the frame of my c2 with nothing connected to the stators and it worked but the ground capasitor seemed to have little to no affect to the output of the radio. I guess I'm wondering if I wired c2 incorrectly originally following the books instructions that said very little about c2 other than to wire the frame to c1 and to a headphone connection and to the 8 or 9th tab on the switch also wiring the stators together only on c2 if double gang. I was just going over your video again and realized you do indeed have something wired to the stator of c2 and started testing things on mine now I'm a little confused as to whether my new wiring is correct or not.
Very simple explination without complicating the subject. Please publish more videos on the cb transmitters, together with the cat.
Hi. To anyone who needs germanium diodes, it is possible to find them in 90s digital telephones, you just have to test all diodes because they look similar to the silicon ones. Greetings from Peru
Very well done. Great video and explanation of RF theory. Love the cat, too. Looks just like my Oscar.
Can I build crystal radio with the actual crystal and not diodes? And how do I do it?
I Have A Question, 1:55 HOW Would You Know Where to Tapp In The Wires ? Like, HOW? With Some Kind Of VNA Or ??? I Just Don`t Grasp That, Maybe Someone Can Help Me With That?
Just follow the coil winding instructions in the book "Radios That Work For Free". That tells you where to place the taps.
This channel needs to blow up! i had some headphone that I didn't know how to use
Yes my visitors are amazed. By the fact that radio stations fight to get in. And guarded is my Baldwin head set. And a salvaged tank head set. Ps I do on ocasion use a couple low volt led to make a verry small lamp. Shutting off my room light. I see the room light up. As my vision corrects. And almost see well enoufgh to make notes. Or tune another set good show om 73de kv4li
I am more than a bit bewildered by the circuit.
Take that coil switch. Position One (Left hand)
A small amount of inductance (a few turns) is connected across the tuning cap forming a parallel tuned circuit and cannot possibly resonate in the AM band..also known as Medium Wave. Any signal which might survive has now got the rest of the coil acting like an RF choke in its path to get to the anode of the germanium diode.
As the switch is moved to the right, more and more inductance is placed across the tuning cap and at the middle, only 40 turns worth can be tuned which won't make the Medium wave.
When the switch reaches the right hand contact... the diode is now grounded on its anode and there there is nothing to
detect/rectify.
One simple question..AM I MISSING SOMETHING?
I look forward to your help, (is it) John? Thank You.
The redeeming factor is that the goldurned thing works!
I like the concept of that little radio of yours. I could make a wooden casing for it to look like a sort of a victorian era wireless. Where could I find a wiring diagram for this type of radio? And how should I decide the positions of the taps on the winding? Lovely series by the way. I also have countless old radios in my room, in the dinner, in the garage, all of them have tubes, and all of them are working.Additionally I have an oscillo-synchroscope, two old tape recorders, four turntables and a still working old ring ring sort of telephone with the huge dial. I have even managed to find a 16mm movie projector, perhaps from the 60's, and it also has 4 tubes for the amplifier, and a big one as a rectifier. In the olden days everything were just better. "Simplicity is the ultimate sophistication." as we know..
So long Sir!
Hi Istvan,
I recommend that you get the book I talk about in the video: Radios That Work For Free by K.E. Edwards. It has the diagram and parts list for this radio. If you are inexperienced with radio building, you will find a lot of necessary information. Find the book on Ebay or at Amazon. Good luck!
Many thanks, I have alredy looked after it. I am also building a small Stirling power unit, much like the Philips mc1000 Generator. I'm afraid I got obsessed by some sort of a worldwide catastrophe, so I keep gathering tools drawings and information how to build equipment for such an event, as after it, there may not be working internet or computers, and only old analogue stuff would work. I even have many plans printed.. Strange I know, but in such a situation I will be utterly happy :D
🤔 Squarewave2, what's your cat's name again? 🤨 I must admit, the ol' rascal looks very nice!😻
The video was great. The only remark I have on safety. If you have 100 feet of wire up high it can attract lightning it might be a good idea to have a lightning arrester on the pole outside. So the lightning doesn’t come inside. 🤦♂️
hey, I plan to build an demodulator/amplifier using a NE555P chip by attaching the coil wiper to the threshold and trigger comparators and then the antenna has a connection to the control voltage pin I think this is a high impedance transistor that can act as a diode inside the actual semiconductor.
Wow dont know how I got here but I watched the whole thing and this was pretty cool and more useful then whatever I was about to watch so thanks lol
Mr Dillan made an excellent job. We just adopted a black and white cat similar to yours...her name is Lana Viveka. On the radio side my son built a couple of Crystal Radio examples for his science fair and worked fine except that the place was too noisy for the judges to hear well but my son did well. Thanks for the explanation. Love your videos except for the spiritual world one on which I disagree completely. 73, YS1RS.
Who else are here after watching Praveen mohan video
@squarewave2 Hello sir, I love this build. I had a couple questions, I know this build is an older one of yours but I was wondering if this radio would be benefitted by adding a antenna coil or does having the looped coil make that a pointless addition? Thank you for your time. My assumption is that yes it will anhance its performance. Also I see the wrapped antenna on the cover of the book you have there. My question is in regards to it's practicality. Would somthing like that work effectively or is it better to simply run your antenna wire covering as much distance as possible as high as possible as you've stated. Again my assumption is that it probably does "work" but not nearly as good as the standard layout. Again thank you for your time.
Hi Bran Man,
This circuit does not need an antenna coupler. Rather than trying to add one, you should just start with another circuit. The big loop antenna on the cover is fun to play with because it is directional; but depending on its length, a long wire antenna will do better. Thanks for your comment.
@@squarewave2 thanks for the reply. after some reading I came to the conclusion that it didn't need the coupler I got the book it's awesome. I bought two variable capasitors 365pF and a Alpha 1 pole 9 position band switch I looks to be the one you used as well actually. Now I just need to go get my 20 gauge enameled wire the head phone terminals the diode and all the rest of the bits and bobs lol I'm super excited to build it. What other bits do you got here that's not in the original parts list in the kit. Are you using the normal terminals for the antenna and ground connections? The coil might be a little bit of a challenge but I think I can get it done. Also what gauge wires are you using for your connections looks like maybe 20 0r 18 gauge. Also what gauge wire do recommend for the antenna and ground. shoukd it be solid copper wire without a insulator?
@@branman3336 Hi Bran Man,
Any terminal is OK for the antenna and ground connections. Use any gauge insulated hook-up wire for connecting the parts. Making the coil taps is tricky, see my video "Make crystal radio coil taps". The antenna wire is stranded for flexibility not solid. It can be either insulated or bare it doesn't matter.Gauge doesn't matter either but heavier wire will be more durable. Good luck with your project!
Hi Bran Man
The capacitor across the phones is really optional. It is supposed to fill in the gaps of the radio carrier wave but I doubt that you can hear any difference. But if you want one, use a .002 mfd at any low voltage value.
Your video brings me over 60 years back when I made my first crystal radio. I new nothing about impedance so the 75 ohm headphone worked perfectly.
Now I am going to build another crystal radio together with my grandson. Unfortunately, there is no more am transmitting stations where I live so the result can frustrating.
You may want to check to be sure there really are no stations at all. Often there is a really awful one you have been ignoring all this time.
my email: hrdstradehub@gmail.com, pls share your email, we need CRYSTAL RADIO
it will be great to buy one from you, which can receive SW
Hey man if there are no AM radio stations try making one with a AM radio transmitter. There’s an easy one you can make with a 555 timer or you could go for an LC circuit transmitter or there are also microcontroller AM transmitters. Anyway good luck with the crystal radio!
I remember building one of these from shoe leather and buttons off dead enemy soldiers. I was in the trenches in Japan fighting off the Nazi invasion. I'd listen in late at night watch to Nagasaki Soki. That's about the time I met that French gal Simonie. Man at the gams on her.
(falls asleep and begins a drop mouth snore.)
Can you do a pdf of the book?
Please????
thats one cute kitty
Both remarkable but only the radio is real. Nobody leaves our enclosed realm (Genesis 1:6-8). Thanks for the video. Excited to make something so awesome.
Can you also make a homemade speaker? Would be cool to see a full homemade setup
I could only get about 2 and a half minutes in before the constant lip smacking started in on me.
receiving a transmission is free but is there a way to analogously transmit signals, or does that have to be powered by an energy source?
No. The power for this receiver was provided by the transmitter.
you need watts of energy to transmit ...
Very nicely made. I also made one using a galena crystal and they are tricky. The box says 1924, price 2/6 and says it contains 2, 3 or 4 crystals, a special contact wire and instruction pamphlet. Was I robbed? I paid £3 for one crystal in the tin box. I remember reading somewhere the wire was phosphor bronze.
Bill, G4GHB.
I also remember 'Wood's Metal' was used to mount the crystal. Whatever that was.
Bill, G4GHB.
Hi Bill,
I can't say it you were robbed. I am not familiar with your money. But thanks for your comment!
Just picked up the book, there are a number of them available for a reasonable price on amazon. Looking forward to seeing how you're winding your coils.
Thank you for the good info on the book! I'm glad to hear this. I am beginning to work on my "Coil Winding" video today. Happy Halloween!
Actually... I've got a roll of 45 AWG copper wire, thinner than a human hair; I've always wondered what would happen if you put that on one end of a Mylar balloon and use it as an antenna. Wind currents mean that it's unlikely to be a truly straight wire antenna, but it could probably get pretty high.
theorically a 45 awg wire wound over a roll several miles could produce some ac voltage energy from the tremendous resistance of the setup
Love the cat...
How to catch COSMIC RAYS/WAVE for we get free energy
I wonder if the energy picked up on a longwire antenna is enough to activate the base of a transistor.
Yes you can as an amplifier!
have a capacitor storage will travel
Even some of gen alpha is going to be interested by crystal radios.
About 80 years ago my grandfather moved next door to a radio station that had around 50kw antenna. He built a giant array of crystal radio sets and wired them together and it provided him with free electricity that resulted in a greatly reduced electric bill. But I didn't really believe him. Two years ago I moved into a new place and directly across from me is an A.M. radio station and it's very big antenna. I am less than 100 feet from the base of that antenna. So out of curiosity I built one crystal radio (I made one as a kid decades ago) and included an LED in the circuit to see what happened. Well dang if it didn't light up. As it happens I bought a few miles of copper wire a few decades ago at a yard sale for less than 1% of the normal price, actually a fraction of the scrap metal value. Being the pack rat that I am I brought it with me when I moved. So...
I got me a little power plant and since I've recently converted to all LED light bulbs I now have a very bright house and yard and pay 0 for the light bill. It's not enough to run the A.C. or other appliances but it takes care of about 10% of my electric bill and honestly the only thing I had to buy was the crystals, a small investment for what I get. I figure I'm saving about $180 a year in electric costs and I think I spent maybe $30 on the crystals at the flea market. Of course winding all those coils took weeks lol. My neighbors think I'm crazy with all the antennas under my soffits. A funny side affect though is that even without any speakers my whole house reverberates with the radio broadcast. At least the programming is pleasant.
First real "free energy" diy
Can you harness or convert the reception of radio waves into voltage power scale it up and have free energy?
There is no such thing as "free energy"; and there is not enough "energy" in the received radio signal to do any real work.
If you could "scale it up", the energy would still not be "free". It took power derived from a coal or hydroelectric
plant to power the transmitter. The answer to my title "free energy source?" is NO.
Nikola Tesla... crystal energy radio and crystal receivers
@@squarewave2 BUT, off-planet RF is free to *us*.
you could light up leds i think...Thomas Henry Morray was obsessed with crystal radios as a child, he supposedly invented a free energy device that lit up kilowatts of bulbs...of course it all happened in the 1930s if it was all true as reported
What would you need to broadcast a signal?
You will need either a radio amateur license (ham) or just to fool around, an AM radio broadcaster available on ebay.

Dear John, Please stick to science and especially to our beloved crystal radios. You are far too nice a guy to taint your appeal by talking about things you know are gonna polarize your listeners. Don't mess about with a broadcast which brings us all together via science; your erstwhile talking in the realms political and spiritual is screwing up the laid back appeal of your delightful journey into radio science. An occasional philosophical foray is acceptable to me, but l feel lately it has become a more frequent and annoying aspect of your great presentations. I tune in for your approachable style and your accurate information, delivered only as a scientist and teacher can. Let me say I love your absolute dedication to doing as good a job as you can do. Nothing is ever haphazard. Joints are never cold soldered-you do not scrimp, nor will you tolerate anything less than your very best.
As I say---I love your videos. I learn, I do and it is part and parcel of that "stuff" which keeps me going at an age where my compatriots of old are slowly but surely being assimilated into the couches they sit upon. Thanks for reading this; it is basically a hope you will ease off a bit on the philosophizing and get back to John. Best regards. I am,

How many galenium diodes are needed?
Only ONE, as shown in my schematic.
I have a home made crystal radio. My goal was to illuminate an led without any local power. I tried all sorts of things, but i never got it to work.
I am not sure if there is an optimal setup, but i am still working on it. By the way i like your cat. But i think the cat attacked your radio because it heard you say you used a cat's whisker.
yeah thats what i dream too lighting up leds with such a contraption..im sure its plausible with proper capacitor storage and resonance
estan muy buenos sus videos, pero no se entiende el diagrama o esquema que ud muestra comparado con su crystal set radio, el aparato , muestra conectado los dos condensadores en paralelo , en el diagrama no se ve eso van en serie, le ruego ponga el circuito y bobina con sus derivaciones, el calibre del alambre de cobre etc. , gracias
Do same one know to do the real diodo of oxide of metals?
Bravo !
Interesting never knew that this was possible
When I watching this video, I find this;
1. You just looks as old Howard Stark
2. And you just looks similar as A.W Tozer
Your KIT is great as always.
Great channel actually.

Is this zero point energy ?
No sound!!!
Ever looked at "Earth Batteries"?
Yes and the term is not definitive.
Earth Batteries describes either magnesium primary cell batteries or a type of polarized capacitor that can act as a primary cell battery depending on circuit conditions.
Neither is truly "Rechargeable", but either can be accessible sources of electricity if someone is in an emergency situation.
In a non-emergency situation, they can be quite costly.
A primary cell eats the cathode, usually leaving a salt after it's been exhausted. The best 'earth batteries' are setup to be refreshed from time to time, but many of the "Free energy" designs assume that the electrochemical reaction is inexhaustible, and thus don't make allowances for it.
Mr. Teslonian here on RUclips did some stuff with earth batteries a few years back that i watched quite carefully. it was interesting, but it's not the answer.
What size wire?
Hi Ted,
Use 20 gauge enamel wire.
need the tesla tower near and hold quartz lol.... will shock you and make you godly and the ability to control all elements a push or a pull depending on the elements charge... bites like a snake fyi... crystal energy radio and crystal receivers that piezoelectricly charge you up
Thank you for your comment! But I can't make any sense of it. Can anyone else??
look up how ultrasound and rc cars use quartz on both ends this energy controls all elements a push and a pull. in this vid there is a tesla tower that lights up a picture tube which is quartz inside if he would have touched the bottom of the tube it would have shocked him energizing him like a van de grafft generator ruclips.net/video/7vRcDLEiRaM/видео.html
