I love crystal radios, so UA-cam looked into the internet time machine and sent me here. &5 years old now and building them again.
I tried this 20 yrs ago when I got alittle electric shock while I was connecting antenna of my first crystal radio which worked fine but I gave up and prefferred going to the beach 😉😉 keep it up my pal👍👍
why did you hook the positive end of the LED before the diode and not after it? would it make a difference?
I think he said in the video, but regardless, it should work in either direction, because crystal radios flip flop their phases as the coil and capacitor oscillate, so both directions should work. One way might be brighter than the other way slightly, though, if the earpiece is soaking up some of the energy while in the same direction? I have no idea if that would be a meaningful amount of influence at all, though.
I should have shown that I have a switch which allows me to turn on the LEDs or the headphones. If I have them both on like my diagram shows the LEDs aren't as bright.
A smart survivor, Leben leben überleben Lilly.
Sorry I didn't notice your question sooner Lilly.. The LEDs could have been placed after the diode, but had I done so there would be slightly less energy to my lights because of the voltage drop that occurs across a diode. The voltage drop is less than a volt which isn't much, but I wanted as much energy as possible going to my lights.
You are the only kind of friend or neighbor I want. This is inspiring to me beyond words.
With any radio you are always intercepting some energy from the transmitter. The transmitter is radiating 5-50 kW so your interception is quite minor, I am very impressed that you are lighting up all those LEDs and receiving perhaps 20 mW of power (assuming this is not a trick)
For those who haven't see the interview I made with the author of a book on crystal radios

If you build 2 crystal radios and put a volt meter on one, you can see the load being applied to the other.
Back when I did a lot of experimenting with crystal radio's I found that making the antenna a big loop and tuning it got more power received.
Very cool Rf for power. There is a transmission line a few miles from here, and it gets kinda low going across the highway. One day not long ago I had a tractor on a trailer behind my truck and it rolled backward and picked up on the ball, so I eased over to the side of the highway and got out.
The second my boots touched the soil I got a really good jolt. It is induction from the line into any nearby metal. Tires somewhat insulated the truck trailer and tractor and I completed the discharge path--it was eye opening. Had to jump on and off the trailer and when opening the door and getting in.
I implore you to touch up upon this further in another video. This is truly amazing stuff, I don’t know why this hasn’t been looked into more. I would love to see the potential this could have for humanity
The power level here is so low it doesn't have much potential. It requires a long antenna, and you need to live fairly close to a AM radio station for this to work.

This has been done for many decades. As a kid in the 1970s, I built a free power device from the book "104 Easy Projects for the Electronics Gadgeteer" but I changed the diode to a full wave bridge made of germanium diodes. Tuning to a strong station generated more than enough power to power a one transistor regenerative receiver that required .6 volts to function. The regen itself was based upon a 1960 article for a candle-powered radio by Professor Massoud Anwar, but I replaced the thermoionic battery with the free power device from the aforementioned book. So, this is nothing new, people just seem to have forgotten about it. Think about it - Maxwells equations, the work of Farraday, all pointed to an invisible force field generated by electrical energy - an electromagnetic wonder - all of those power lines are sending out these magnetic waves that when crossing a conductor generates a current - so this is and has been common knowledge for forever and a day. I don't mean to sound like a pompous jerk, so if I come off that way, I apologize - it isn't my intention - I just want to encourage folks to look into these things and have fun with it.
Thanks, Dave. I like to play around with electronix also. That's how I found the backdoor of the Trip 5 IC - to control the IC using resistance through the reset pin. Of course, one could find that by studying the datasheet, but I was a newbie then and found it by playing around with the IC on a breadboard.
+Robert Calk Jr. I don't know what a Trip 5 IC is but it sounds interesting. There's nothing like learning through experimenting.
+Grants Pass TV Repair
You know, like the NE555, many call it a timer IC.
+Robert Calk Jr. Okay I know what your talking about. I've build a couple projects that used the 555 timer IC
Loved the vid. FYI, RF travels at the speed of light. In 1 second if sent through Fibre optics would travel around the earth many times.
I had a Radionic set many years ago and there was a crystal radio circuit that used the carrier wave to power a one transistor amplifier that made the radio louder in the earphone!
Sounds like it would make a nice edition, although mine is now loud enough to be annoying.
when i was a kid i asked my teacher if its possible to make free electricity from radio signals! i was 10
i didnt realize how smart i was till i got old! and dump
if any of you have a smart kid (weird kid) dont make fun of him coz he is smarter than u!

The electricity isnt free. Radiowaves are transmitted from local stations which are funded by advertisements and listeners.

I have so many questions and not enough answers. I stumbled across a video of a guy in Zimbabwe powering a TV via radio waves. Immediately I new this could be possible with the proper step up transformer and various other solid state devices.
That radio is cool, great job!
Unless someone lives right next to a radio station there is no way you will get enough power to operate a TV, People who make such scams are generally fakes. I made a video on this topic, and so have many others. ua-cam.com/video/d0UjhHUrO74/v-deo.html
@@GrantsPassTVRepair But that man from Zimbabwe really did it, its not a scam.
This video earned a thumbs up. I've built four radios and all were fails. Its non-giggity disappointment especially after hours of soldering and winding and drilling.
Now powering these LEDs is basically witchcraft as far as I am concerned. Who has this type of gray matter in the membrane? Not me, apparently. Kudos to this guy.
Thanks, nice antique too.
Late Thomas henry morray was fascinated with crystal radios as a child, he went on to make a free energy machine in the 1930s that made over 50kilowatts! (but I suspect it had radioactive matter placed into its components)..great video, it reminds me of Tesla, Morray, and many others who went into this kinda research! great looking envy making coils, keep up the good work...amazing part is that crystal radios work like shorted circuit that has an air coil in between the Antennae and the Ground, a tiny capacitor parallel to the coils, and a diode taps on one end of the coil to the high resistance earphone! its like listening in on the dc pulses of a short circuited coil!! my fascination with bedini coils started this fever 3 yrs ago!
Isaac Allgood there’s only six sentences. So they missed the last one, big deal. And anyway that isn’t hard physics (even if a lot is... questionable.) so maybe it’s just not that great of a comment?

Congratulations on your device
Some thirteen year old kid made this and everyone was getting all hard and claimed he was a prodigy
I saw the video about him. I'd guess he probably lives close to a radio station as I do.
Thanks to media there!
just need to invent a crystal set that syphons radiant energy from space rather than radio waves from radio stations and we will be set :)
@@infinite8382 I believe that is what the "Ray Tuner" was designed to do. Back around the turn of the 20th century, there was a term describing the "rays" that made up the "ether" in our atmosphere, but, it escapes me at the moment.
@@Mr25thfret I don't have a scientific brain, it's all dutch to me, for if I did, I would invent such a device, but it seems T. H. Moray beat me to it ; ) The rays from space are somewhere on the higher end of the electromagnetic spectrum I believe, possibly gamma rays. It's also called, an oscillating cosmic ray pump, which syphons the cosmic rays of space and converts them to usable electricity. I've said too much, the FBeye will be knocking down my door momentarily ;p
Nice video thank you. How many Wat or Volt the LED/SMD should be in order to be used for this experiment?
The "loss of power" in the transmitter coil is due to the current induced in the receiver generating its own opposing signal. So the loss of power is not instantaneous - the signal needs to get from the sender to the receiver and back before the sender feels that loss. It travels at the speed of light. If you move receiver and transmitter very far away from each other I guess the effect should still be similar but the reflected power would be surely below the natural electromagnetic noise floor so probably can't even be measured.
Amazing that you can pull so much power out of thin air!
I think there is something different going on between the two coils presented towards the end of the video. In that case, there is some inductive coupling, whereas no inductive coupling is required to tune in a radio station.
I like the way you recharge! This and detecting magnet twiddling were two of my favorites.
+KludgeCraft
Yes I agree there is a difference in the way an RF wave is created and received, but as far as the electromagnetic wave itself goes I think it's characteristics are the same as a 60 hertz AC wave but faster.
I think all of us techs need a little recharge time in search of our sanity :-)
+Grants Pass TV Repair the two coils you pulled out of a former would normally be magnetic coupled. Near field inductive coupling requires both coils be tuned to the same resonant frequency, and then needs no ferrous core.
+KludgeCraft Yes... such great efficiency. Put 1000s of watts out and someone miles away can collect milla to microwatts of it. This primitive 'science' is explained by the Friis transmission equation which single-handedly debunks any type of 'free' energy harvesting via electromagnetic waves. While his millawatts are 'free' its at the expense of someone else burning craploads of power to put those signals into the air.
Yes I'm well aware that this kind of energy harvesting is inefficient, and that someone else is paying for this energy, Nevertheless I still find the science behind this means of energy collection thought provoking. My own experiments with electromagnetism and induction would suggest that "Friis transmission equation" is probably correct, There's no "free energy" here, but since electricity and magnetism are not completely understood, I like to keep an open mind that perhaps one day someone will discover a new principle along these lines that will shed some light on what we think we know. I believe the universe is full of mysteries that need to be further explored.
+Grants Pass TV Repair Truly comprehend maxwell's equations and there will be little that "is not understood". However, there plenty of people who would prefer to be mystified by all the cool vernacular & applications as opposed to working through the mathematical rigor of known science. The cellular network wouldn't stand a chance of existing without incredible understanding of electromagnetism. If you and or others try to derive it yourself in a shack & ignore the work of others for the past 100s of years you will not get very far. One wouldn't understand a breakthrough even if it was right under your nose without the relevant theory.
Something I did years ago, but the led hardly lit up even with the strongest of signals, I'm now using solar power directly through panels and an inventor, it helps when you have solid reliable light for many hours of the day

hi ! as u harness alternating current u got it set up for receiving only one definite frequency ? am i right ? is it possible to harness electricity from all frequencies and add them up ? i am thinking about spiral coils and open circuit receiver the one tesla use. alternating current can be harness only by closed circuit receiver but how about impulse discharges that are all around us but impulses dont have difinite frequency. like in dc u got no frequency, in ac u got constant frequency but as i know impulse has no frequency but it creates oscilating current in the conductor it was diacharge to and the frequency is not constant. sorry for my english

LOL I did this back in the 80's while I was in the Navy I used a Mini-mag Flashlight and got it to light up. Yep this works because everything gives off RF energy
How
In the late 60 s I built a receiver transmitter that used only the power in the air. Transmitter would not change but receivers after would have less energy to work with.energy is conserved.
Amazing
So rather than LEDs, could you run few of these radios into some graphene capacitors to charge them? Great video, brother!
Interesting project. Mine is similar but based on different assumptions.
Galena: crystalized lead (lead sulfide). A natural semiconductor. Quite similar to germanium (germanium sulfide).
It appears you have the strip of LEDs wired in parallel. Also, it appears that the wire closest to the top is tapped onto the jct of the antenna and coil while the lower wire bonded to the ground of the variable capacitor. Am I correct on those observations?
Also, there does not appear to be any resistor in your LED circuit a resist. As far as resistance is concerned, since some of the RF coming into your radio is being used to illuminate your LEDs, will there be a loss of audio notice in your ear phone?

I made years ago several scrubby crystal radio receivers. Maybe using a good antena and having a relatively close emitter you can make some LED glow. I can't make a single one with the receiver that last survived at home, in it's current status. I personally find it difficult, but maybe with proper calculations/measurements one can realize if there's such power available. What I can tell is a lambda/2 CB antenna and the mains ground deliver enough power within a crystal radio that one can plug in an 0.25W 8 Ohm speaker (transformer was used to adapt impedances) and perfectly hear the radio stations from 16km/30km away without the requirement of any headphone. I also was able to catch SW transmissions from China here in Spain during nights by properly tuning the LC circuit. Coil was based in ferrite core, not air coils. Was available power more than 20-30mW???? (I assume that necessary to light on a LED) Perhaps if the speaker was driven at audible volume... but I still think, with all due respect, this example is quite weird.
Back in the 1950's Popular Science magazine published schematics and plans to build a small transistor radio. The source of power to run the transistors came from a TV antenna connected where the battery would normally connect. The TV antenna had nothing to do with gathering a radio signal. That was accomplished by a normal radio antenna. The TV signals from extremely powerful TV broadcasters was used for amplification power only. Sorry, my memory of that project is kind of sketchy. It has been almost seventy years ago. By the way, with a good crystal set antenna and a good ground, you can touch the two wires to your tongue and feel the electricity....or strike the two wires together in a dark room and see a spark.
you can use the radio transmission turn it back into electric from a non powered radio like ones that don't take batteries and work .
How
There's an inventor in Zimbabwee that has invented a car that runs on radio waves , a tv that works on radio waves and a genterator that runs off radio waves and produces enough power to run several house . However the West refuses to allow him to bring his inventions to the people . Someone ( The West most likely ) has tried to kill him but luckly he is still alive . These are just some of he inventions . Check him out ? His name is Maxwell Chikumbutso .

You don't want to use the earth's natural energy ;) Good link, thanks for the share.
Magnetic coupling and electromagnetic resonance are very different. Unlike a transformer, your radio is a grounded tunable RC tank circuit with a rectified output. There is likely a radio transmission station within a few km of your antenna.
Your correct. We have Two AM radio stations about a mile away, One of them puts out 10,000 watts in the day, and 48 watts at night. I can tell by the intensity of the light when they lower their power.
Perhaps you might charge some form of accumulators to get bursts of usable Wh.
@@GrantsPassTVRepair So technically it's not free energy. The radio station pays for the output power.
@@erikk77 Yes this is correct. the power is generated by the radio station as I mentioned in this video.
I'm also able to pick up quite a charge on my antenna when thunder clouds are gathering, but that has nothing to do with the energy I'm getting from our local AM broadcast stations.
What happens if you scale up the crystal radio, can you get more power? The question is kind of stupid and the answer should be obvious, but just in case the technology has some physical limitations?
Hello great work. Im interested to learn how rf energy works. Can i get more information about the book? Thank you! God bless.
Here is a link to a website which sells Jim's book. www.hopeandallen.com/rtwff.htm

Nope. Just radio waves. Sometimes I'm able to pick up a good charge in a thunder storm, or when there are charged clouds up above, but no fake claims are being made about any solar winds, or the earths magnetic fields..
I have question, hope someone can answer. Is the electricity constant and if put at the end something to multiplicate the voltage (same principle of a taser) will it work ?

Hey. if u have a receiver that can be tuned to 7.83hz with a mast tall enough for your voltage potential and how large the mast hat is also important for how many charge carriers you can collect
was just wondering if you have had any breakthroughs
Can you tell us about antenna? How you did it and is it vertical or helical? Inside or outside?
I will appreciate any advice. Regards
+Kamil Domjan I used my kite. I had a perfect wind which allowed me to fly my string right over the top of a pine tree, and when the wind died down the kite landed I then tied the end of the string to a spool of insulated stranded wire and pulled the wire right over the top of the tree. I'm guessing the gauge of my wire is probably 22 gauge, and the tree is probably at least 100 feet tall. I believe It helps to keep the antenna away from any buildings and tree branches which can dampen the signal, but I had to use the top branches to support my wire. My antenna is similar to an inverted V but its' end fed rather than center fed. and one leg of the V is almost vertical.

I live on top flor of four floor building in small city, I hope that helical antenna will work for me but I wonder what you think and what will you advice to get best results? By the way I reviewed my book from Jim ;) with signature ;) so thank you so much for the link to his website!
Congratulations on getting the book. I suggest you use a long wire antenna if possible, and figure out a way to keep most of the wire away from the building if possible. Using a kite can help you get the wire where you want it, but if you do this just make sure there are no power lines near by. That kind of power can kill you.
Hi there. Ive been researching ghosts for a while, and ive been trying to derive a way of potentially...idk...creating a trap/area denial device to prevent harmful hauntings from continuing.

What amazes me is that one of the basic components, electricity itself, is so underexplored. We have anomalous thrust/weight loss in both symmetric and asymmetric capacitors when charged at high voltage (many experiments prove that it's more than 'ion wind' or drift.) and we have high-inductance coils that delay the rise-time of the opposing magnetic field in a standard generator topology - a Lenz-plus motor/generator. Just retard the timing, just like in automobiles, and use Lenz to pull in and push out, rather than go against the inducing magnet.
How can I draw more current from the air? Is this possible?
This is Tesla's greatest trick he played on the world. Radio transmitters were based on the Tesla coil. Now you have access to wireless energy provided by your local radio station you just need an antenna like this. Need more power add more antennas like batteries in a toy car
Do you get more energy if you shoot higher rf frequencies at your antenna?
No. a long wire antenna such as I used would not be resonant at higher frequencies.
i have that book . eggscllent :)
Its already been manufacture in smal scale in Philippines
Can this be scaled up to bigger power outputs?
Yes it can be made to produce more power, but even if you managed to scale it up to double or triple the power output it would still be extremely small unless you live right next to the radio station as I showed in this experiment. ua-cam.com/video/yqljaKjKjd4/v-deo.html
I KNEW someone had to understand exactly what i was thinking.
Seems in my personal life I’m around the wrong minds
Hii sir,
this question that suddenly jumped into my mind when i saw your video.. has got nothing to do with your video btw.
just that i never got an acceptable under on this question. here it goes.
Since Energy cannot be destroy or created.. only changes form.
I am very curious why is it when my portable 2 stroke electric generator when powered on, when i fire up my load (for example a bulb), the bulb light up, but when i remove my bulb, where the energy goes ? (in this case is the ac electricity..) where on earth it goes ? since the loaded and unloaded condition of the generator is the same, motor is running at the same pace, and consuming the same amount of fuel.. where then the energy that generated goes when i unplug the bulb ?
if you have the time to answer my silly question... pls do.. i would love to know something i am most ignorant of.
thx
andrew
Unless you have some kind of load on your generator, I would assume the energy doesn't go anywhere. Just like a battery without a load. Nevertheless if we had the ability to look into the invisible world, I'm sure it would be interesting to see what kinds of interactions are taking place between the magnetic field and the coil with and without a load.
Empty space would be a space with no matter or energy, but the traveling electromagnetic wave carries energy once it was emitted. It will carry this energy forever until absorbed by something. That is conservation of energy
+movax20h I understand but It's hard to imagine how empty space can carry an oscillating electromagnetic wave. To me the fact that it does suggests "empty space" has some form of matter which acts more like a medium to carry the oscillating wave. Much like what you see when you drop a rock in a pond. Once the source of the wave is gone the ripples continue until they are dampened and undetectable. Here's video which proposes another theory. ua-cam.com/video/5AUA7XS0TvA/v-deo.html
If you would have a zillion of such devices in the room, would be there be any signal in the room and would all signal have the same strength ?
What is the limit ?
I'm not sure, but it sounds like an interesting experiment. I noticed my other radio becomes quieter when I tune my crystal radio to the same station, but as one viewer explained it's most likely due to the the transmitter signal being re-radiated by my crystal radio slightly out of phase with the station transmitter. The phase difference would be from the small time difference between the re-radiated signal and the transmitters signal creating a null in the signal.
Some things in your house reflect radio waves decently, so there would probably be some bouncing around normally, and one device could soak up some of that. Also even in a direct line, if one is shadowing the other from the direction of the station's signal, then it might soak up some energy too.
Stewie Griffin the power is brought in using a 200ft antenna wire then resonated with coil and capacitor. A few tens or hundreds of milliwatts are available depending upon how far the antenna is from the transmitter and how powerful the transmitter is. RF energy diminishes by the square of the distance. it gets weak quickly with distance. Must live very close for this to work. Aloha.
I had this idea once. Looks like I'm not alone lol
As long as you live close enough to the radio station transmitter it doesn't take much to light up an LED. ua-cam.com/video/vHVmJ5lD9jc/v-deo.html&lc=z22dfjeixvfjitpiz04t1aokgifz2wvyoeq2v4wchqaxbk0h00410
WHat type of radio is that? i need one of those for science fair. would be great if u can show how to make one
It's called a crystal radio. Here is one I just found through google. ua-cam.com/video/VqdcU9ULAlA/v-deo.html
How far away is your local station and what power is it running? I suspect it must be quite close to be able to light those LEDs
The radio station that provides the power is about one and a half miles from here. In the daylight hours they transmit ten thousand watts, but at nigh they lower their power down to 48 watts. My LED still glows when they lower their power but it isn't as bright, There may be some additional power coming another AM broadcast transmitter at night, but I haven't verified the source that lights up the LED at night.
so does this work with higher electro magnetic waves, like visual light?
Look up photoelectric effect.
A antenna for visual light frequencies would likely be too short to build by hand. Take the speed of light / the wavelength of light = frequency of light
This technology can be used on street lights. Its clean energy. No power cable and RF waves can be seen in most parts of the world. Sp can be installed on street lights.
Doesnt seem very cost-effective, but its cool. If they can harvest cosmic radiation in future, it can help to power interstellar probes like Voyager for centuries. Still, nuclear generators are probably the primary choice then. Unless it becomes a very handy and improved technology.
That thing is actually quite old, the description still calls it the lamp socket or light cable. haven't heard people call it like that for manny years, last time I heard normal people use it was in the days that electricity in manny forms was called aether. or up to around 100 years ago for the last ones, while it actually was more like 200 years ago when electricity was just discovered as something you can actually use but was well known enough that there was actually decent amounts of research in it.
It says lamp cord. This isn't an archaic term, you can find spools of this stuff today labeled as such in any hardware store.
Your work really stands out, and I would like to replicate it...🤔 but at the same time I would like to know how tall and long is the antenna cable or if it is connected to a dipole?
Science mentions that each meter of height represents a higher voltage, that is to say that with a lower antenna you will surely not get your result. When it suits you, please tell us about the height of the tower, type of cable (ohm) and if it is connected to a dipole or antenna... I presume that it is not energized indirectly through of some RF amplifier 🙄 It is also of interest the nomenclature or characteristics of the LEDS (voltage range to work, etc) that I will later look for and expand through Datasheet... Best regards and thank you very much for sharing!
My antenna is just a long stretch of wire which is about 200 feet long, and it's strung over the top of a tree which is about 75 feet high. I live about a mile from an AM radio station, and this is why I'm able to derive enough power from my antenna to light up an LED, I used insulated stranded wire for my antenna, The wire appears to be about 20 gage.

One self taught engineer from Africa
Somehow makes cars and helicopter, that is power by radia waves
Please send me the link if you know it.
I read that paper or cardboard coil forms will sap some of the energy you are receiving. I like to put a proposed coil form (less any wire or metal) in my microwave oven for 30 seconds and feel if it gets warm, if not it is good for a coil. I liked that old crystal set you found. I like spider coils also and Litz wire. I wish they would bring back shortwave. (no thanks to Obama).
I guess that explains why some of the coils I've seen don't have cores
Please send me where I can get that book thank you I want one
If you go this link you will find it in the info on where to buy the book in the info section ua-cam.com/video/G4YDsvv1DEk/v-deo.html
Hi Sir do you have a video tutorial fo your crystal radio especially the upgrades you've done?
I have an index on all my videos at www.tvrepairinfo.com/ , but you may enjoy my video called "2 dollar radiation detector you can build." It's not about crystal radios but a similar idea or harvesting power in the air to light up LEDs. Here is the link. ua-cam.com/video/vHVmJ5lD9jc/v-deo.html
Thank you Sir
Vary good
Hi thanks for the efforts..where can I get the book

Which version of the book has the schematic for the set that you use in the video? What is the power and distance from you of the radio station that powers the unit?
I'd guess the radio station is about 1 mile away from here, and their day time power output is 10 thousand watts, but at night it goes down to 50 watts. The schematic I used was in the first book. Did you see the interview I did with the author called radios that work for free? ua-cam.com/video/G4YDsvv1DEk/v-deo.html
@@GrantsPassTVRepair I saw the video. It was nice. I really want to light 10 LED's like you did.. I have a 50KW station 3 miles away. Do you think that would be powerful enough to duplicate your setup?
@@kafr8413 I would think it should work with a 50 KW AM radio station only 3 miles away. At night when our local radio station turns their power way down to around 50 watts, I'm still able to get a faint light off of my LED. I think the key is getting a nice long antenna wire up high. Mine is about 200 feet long. Also note that my LEDs are all in parallel. Did you see this other design which is easier to build? ua-cam.com/video/vHVmJ5lD9jc/v-deo.html
@@GrantsPassTVRepair That is really simple. I will build that one instead. Thank you for the suggestion.
@@kafr8413I don't know if it will pick up signals as well, but best of luck on your project. By the way here is one more experiment that may interest you. If you try this please be careful about high voltage wires and electrical storms. ua-cam.com/video/yqljaKjKjd4/v-deo.html
I would to love to find that at a garage sale
Want to know where you purchased the 1N34 diode? have tried allelectronics and fry's no luck
If you google those numbers you will find many retailers who sell them.
Thank you found them....have you tried the 1N34A? Does it work as well?
I don't know if there is any difference between the 1N34 and the 1N34A, but the IN34 should work well. When you put up an antenna just make sure it's good and high like this one. ua-cam.com/video/Xz5BCh0kAOQ/v-deo.html
u said you have a book that's tells u about am christel radios I might be interested in that book u have in you're video iam not asking for it or saying I want it. I might be interested in it
Hello ! I wonder if it is possible with the suitable antenna, to detect with a diode the signal of the digital television. and turn on some LEDs. (1kw DTV station nearby) I wait your answer. Cheers
I'm sure that would work, but I'm not sure about the range you would get at those lower frequencies. Here is a video where I demonstrated something similar to what you're wondering about. ua-cam.com/video/vHVmJ5lD9jc/v-deo.html
@@GrantsPassTVRepair According to it, dtv works in the order of 400-600 mhz, I don't know what type of LC tank should use for that frequency.
Try magnetic neutralization video, with that 26 pounds coil and permanent magnets you can yield strong backspike
Very cool.. Love that radio in that box.
How big would you transmitter/receiver have to be to power a car??
you can read sth about it here www.nzdl.org/cgi-bin/library?e=d-00000-00---off-0hdl--00-0----0-10-0---0---0direct-10---4-------0-1l--11-en-50---20-about---00-0-1-00-0--4----0-0-11-10-0utfZz-8-10&cl=CL2.20.14&d=HASHedccacb18da2d2ee0851c7.5.1>=1
If you use a joule thief circuit in that you can light hundreds of leds with it.
That sounds like a fun project.
do it plz
its just a voltage booster ... current goes down
