Recent discussions have lead me to confirm my hypothesis that the energy and antenna used are simply for signal strength and broadcast range? I mean, should you use a simple diaphragm and length of wire, you could broadcast to a speacialy designed receiver with extra amplification abilities, short distances, like centimeters, but that the idea, and ability are sound?

A useful but very simple transmitter can be made with a relay and a capacitor. If I remember correctly, the electrolytic capacitor is wired in parallel with the relay coil, and the switching part wired so that when the relay turns on, it shorts the capacitor (and battery). The terminal of the moving part of the relay is wired to the water inside a PVC pipe. When powered on the combination of the capacitor charging and the inductance of the coil prevents the relay from turning on. Once charged, the relay turns on and discharges the capacitor, making a little spark inside the relay and radio waves which make their way into the water. The shorted relay turns itself off and the cycle repeats at a rate proportional to the capacitance. If an AM radio is tuned to best reception and then swept over the pipe full of radio emitting water the pipe can be traced. I think I powered it with a 9V battery and it was enough to trace a 1" PVC pipe 1.5-2 feet under sand from the well to the house 100 feet away. I'm not sure, but I think I remember it working okay if I just connected the antenna to the well housing even though that is grounded. If the relay doesn't buzz, try re-arranging the circuit, not 100% sure I'm remembering how I wired a circuit I first made by accident when i was a kid.
I am a physician with background in electronics. I am 70 yrs old and since I became an amateur radio in the early 1960’s . I have read all about Tesla, and the hex of electronics. During my many years of training in medicine I came across patients with great stories, some in their 80’s in the VA and other centers. In short: 3 patients, independently told me they worked on the USS ELDRIDGE. Clearing the entire “innards” of the hull and installing generators and RCA equipment that came in crates. One of them was working on the wiring. Heavy duty wires, porcelain insulators etc . There was a fine chain mesh, like “mosquito net” loosely going around the outside of the hull (in the water) that covered that went around the entire ship hull & was bolted to the hull on the sides (ground?) . Several weeks later a pre assembled series of 3 sets 10 foot coils mounted in a 5 “ cylinders mounted in X,Y,Z axis. Each set of the 3 coils mounted in XYZ configuration were installed at the back outside deck, another set on top of control deck and the third on the front of the ship. Each individual coil had an independent primary connected to its own power supply . The bases of each coil was about 3’ from the other two. This is all I could get. I can’t make sense of this configuration using my very basic knowledge of physics and resonating circuits. Just using the right hand rule, the fields of each set of 3 coils would cancel each other. I gather that each the sets of 3 coils were likely connected individually. Using high voltage in 1 set of 3 coils mounted this close would no doubt cause arching to form. Now what do you think the 3 sets of 3 coils far enough from each other would do? For sure some time of resonance wound be achieved no matter if arching between the coils happened. If each individual coil was activated individually within miliseconds of each other they each would work independent of each other on one set. Then how would the 3 sets of 3 coils do anything, even if they were used in something like a phased array? From the information above, I gather that the “Philadelphia Experiment” at least was tried. The stories associated with it may all be made up. For sure this setup. Was mounted on the USS ELDRIDGE. I am very interested what you & the Plasma Channel guy make of this configuration. I asked a PhD physicist in the early 80’s what he thought. The only thing he could suggest is that the coils mounted in X,Y,Z configuration may have had something to do with our 3 dimensional universe, but even then this was just a wild guess… PLESE GET BACK TO ME ON THIS MYSTERY. Are there other circuits besides possibly “insect zappers”, where this coil configuration is used? THANKS IN ADVANCE.. Sergio
Thank you very much. I have just been shipwrecked on a desert island. Thanks to your UA-cam video I will be able to contact civilization. All I have to do now is learn Morse code in a few weeks with another video.
One can use the LO (local oscillator) built into all radios as a transmitter. Inexpensive AM radios generally use 455 khz while FM radios mainly use an 10.7 mhz. The local oscillator is actually a mini-transmitter that is used in radio circuits for purposes of selectivity and image rejection. By tapping into the local oscillator at a certain point, one can inject an audio frequency and piggy back the LO to actually transmit on either the AM or FM band offset 455 khz higher for AM or 10.7 higher for FM. Thus if you tune the radio to 600 khz, you are actually transmitting on 1055 khz on AM. Likewise if you tune the FM radio to 88 mhz, you are actually transmitting on 98.7. Unfortunately , the LO has a very weak output and that is just one of the limitations of using a radio's local oscillator as an emergency transmitter. By adding an antenna, one can transmit a few feet to maybe 200 hundred feet under most ideal conditions. Another limitation is the possibility of getting a shock if you are using a house power instead of AA batteries. Another drawback is the possibility of shorting out your radio by attempting to use it as a transmitter by tapping into the wrong part of the radio circuit. But anyway, interesting video nonetheless...
I like your answer on how to obtain RF out of a radio. A very tiny loop of wire next to that local oscillator is a safer way of extracting that energy. Then, powering the radio on and off will become your Morse code signal. With the way everything seems to be monitored in this world, it would get you some attention.
I’d put a very tiny loop of wire over the local oscillator to extract RF energy from it. Have that wire extend out as many feet as possible. It’ll create a radiating antenna for that energy to disperse. Use the on/off switch as a keyer to do Morse code. That’ll get you some attention.
You know, If you just use a rotary spark gap to get consistent spark timing, and put one element on a rocker(or have really good rhythm) you aren't limited to morse, you can send straight up digital data. And on the subject of emergency transmitters, believe it or not, you can just use a car battery, two wires, and a metal file. Wire-Pos | Neg-wire-file Just scrape the Pos wire against the file very quickly to send hundreds of tightly packed bursts of broadband emf per stroke.

If you go to Tim Hunkin's channel, there is an old episode of Secret Life of Machines from the 80s when he and Rex built a spark gap transmitter using a car's ignition system. Anybody who like this show should watch that whole show anyway.
It was Heinrich Hertz who first demonstrated the spark gap transmitter, NOT Marconi. However Marconi DID take the concept and extended it dramatically for commercial use
That's a "charged" issue. You know "Henry" over there doesn't have the "capacitance" to know better. He just impedes the flow. I'm glad you helped fill the knowledge "gap", less one "sparks" the FCC into handing out fines that "hertz".
Spark gap will come back in the form of ultra-wideband. It will work over short distances at very low power. But every node in an ATM mesh Network will be a transmitter receiver using ultra-wideband. The carriers will be high and dry looking for a ball player. The packets will be able to make hops three orders of magnitude faster than current IP so no backbone will be necessary. And it will be connection-oriented not broadcast oriented.
Ya remind me of myself, when I was your age. Bravo! That was stupendous! Why did you look so much like that law enforcement official? That was real good. I've worked in radio and television now for over 50 years. You're on your way, sport. 50 years ago. All I had was a couple of real for real audio recorders. I would do independent productions. I'd bring them into school with me. I'd play them for the classes. I started my school radio station. This was way back in the early 1970s. Later I spent 20 years with a major Television & Radio network. But also attending a few major music award nominations, on my own. So I know a career driven professional when I see one.. (I bet your dad really enjoyed doing that.)
Subscribed..!! What can i say. You put so much effort on your videos. From graphics, to the smallest detail, to music, to comedy. Have you tried CB Radio? 🙂
Using a CB antenna on your project, while better than nothing, will pretty much tune your transmitter mainly into the CB band, which is woefully lacking an audience on a desert island, and maybe a few harmonics on either side of it at progressively lower signal strengths as you move farther and farther away from 11 meters. Any other hash that your spark gap transmitter makes will be choked out pretty much on every other frequency. Breaking open the center loaded coil and making a "long wire" antenna out of it's wire would create static interference at higher frequencies, (shorter antenna), and with more harmonics to create a more attention getting signal across a greater number of frequencies. It would be best to aim for the aircraft band, (108 to 136 MHz AM), as the possibility of any aircraft flying overhead would hear you on their AM frequencies as your spark gap transmissions would be more apt to open the aircraft band's AM squelch. Most boats today use VHF FM frequencies. While the FM VHF marine band, (166 to 174 MHz), is relatively close to the aircraft band, the FM channelized bandwidth, (25 MHz per channel), and it's associated FM squelch circuit would wash out / block out your signal from ever breaking into it's receiver. Very few ships, except for large ocean going freighters and cruise ships, at sea still use the HF SSB 6 MHz marine radios anymore due to their $4,000.00 to $6,000.00 price tag and very large, low frequency antenna compared to the $150.00 to $200.00 price tag of a good VHF FM marine radio and it's associated, much shorter, less wieldy antenna. While the HF SSB radio would be ideal to receive a spark gap signal, being that SSB radios use a BFO, (beat frequency oscillator) to hetrodyne with the carrier free SSB signal, to be able to hear intelligible human speech rather than something akin to Donald Duck is much more appealing. Your relatively short, "long wire" antenna made from the CB antenna's center load coil, might only make it a couple of miles out to sea at best as opposed to an aircraft's one to eight mile vertical height over head. You might also want to scare up something conductive such as a piece of wire, salt water soaked rope or what have you to connect to the spark electrode opposite from your antenna electrode. Thrown into the water or spiked into the ground, if you can find a piece of metal to use, to act as a ground plane would help to increase your range a bit. Every little bit helps. Keep plugging away, (pun intended). Channels like yours are very beneficial and educational. Thank you for your service.

Because the masses are easily entertained by flashy things and non important sh*t like popmusic and don't want to put in the effort to learn something?
Spark gap xmitters are now illegal bec the signal is very rich in harmonics that is very broad accross the entire radio spectrum, LF through HF and higher... spark gap xmitters emit damped waves, how ever in extreme emergency situations one benefit of being rich in harmonics is when used to send distress signals your signal stands a very good chance of getting heard because of sever RFI it will cause through out the Bands of frequencies used by all radio services, (this is the main reason why such xmitters are now illegal) but you have to knw how to send SOS in morse code, rescue responders will know that you are in distress some where out there in the vast pacific if you knw how to send this three morse characters.
The Video is good, even if acting is not your strong suit, it's still very good, And the information was even better, I did find myself distracted at times, by throwback to childhood, due to a little resemblance of Elmer Fudd in some of your words lol Two Thumbs up if a could!
Mrs Richards: "I paid for a room with a view !" Basil: (pointing to the lovely view) "That is Torquay, Madam ." Mrs Richards: "It's not good enough!" Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window ? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..." Mrs Richards: "Don't be silly! I expect to be able to see the sea!" Basil: "You can see the sea, it's over there between the land and the sky." Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction." Basil: "Why?! Because Krakatoa's not erupting at the moment ?"
...Yes, but how do I make a primitive radio transmitter? If I were on an uninhabited island, rare as they are, recalling this video would leave me only slightly better off, since IMO many of the practical details are omitted. 100 feet isn't much; what does it take to make it detectable for planes passing overhead? How much energy should I be pumping into it? What angle should the antenna be at? How do I adjust the antenna to the length with the best resonance? Would putting in a reflector improve things?
Ships still to this day use spark gap radios for emergencies if I recall - it's not outside the realm of possibility. As per practicality, I was just trying to make an interesting video; it's not practical. Making a signal fire is practical.

This is great, no real idea how radio works, read about spark gaps and coherers but never saw one in action until this video.
A quarter-wavelength antenna over a ground-plane is also a resonant antenna (like the half-wavelength dipole antenna).
Also commonly known as a Marconi antenna.
It's not going to resonate much when driven off a spark gap.

This was obe of the best videos you've ever made, very interesting and funny, it was nice Plasma Channel joined the video. Keep doing this, it was great. Greets form Belgium
Thank you, Jarno. Greetings from Michigan, USA
Obe
Josss bro...really great videos😍😍
Thanks bro
best video yet! loved it
Guaoooo, im so proud of how you make me have a good time, learn, and challenge my self under 15 minutes, this content is very different from everything you see today on UA-cam and I really like it, continue what you do and hope you can call everybody’s atention to learn and experiment. (The last part where you got arrested by the Fcc was unexpected jajaja).

Very cool; I even found your station.
I'm glad that you enjoyed it! Hopefully I shall stay on the path of righteousness
Just found my new fave channel
It’s been 3 years He hasnt uploaded new videos
If you go to Tim Hunkin's channel, there is an old episode of Secret Life of Machines from the 80s when he and Rex built a spark gap transmitter using a car's ignition system. Anybody who like this show should watch that whole show anyway.
It was Heinrich Hertz who first demonstrated the spark gap transmitter, NOT Marconi. However Marconi DID take the concept and extended it dramatically for commercial use
nice pair-up. great presentation!
3:55 Perfect explained!!!
Greetings from germany
bloop rent is amazing-thank you for years of helping an idiot at least begin to understand these concepts
That's a "charged" issue. You know "Henry" over there doesn't have the "capacitance" to know better. He just impedes the flow.
I'm glad you helped fill the knowledge "gap", less one "sparks" the FCC into handing out fines that "hertz".
Entertaining and educational video. Thanks.
This was hilarious! Another great and informative video from BLUEPRINT.
Thank you :)
Spark gap will come back in the form of ultra-wideband. It will work over short distances at very low power. But every node in an ATM mesh Network will be a transmitter receiver using ultra-wideband. The carriers will be high and dry looking for a ball player. The packets will be able to make hops three orders of magnitude faster than current IP so no backbone will be necessary. And it will be connection-oriented not broadcast oriented.
This got me thinking....
Ya remind me of myself, when I was your age. Bravo! That was stupendous! Why did you look so much like that law enforcement official?
That was real good. I've worked in radio and television now for over 50 years. You're on your way, sport. 50 years ago. All I had was a couple of real for real audio recorders. I would do independent productions. I'd bring them into school with me. I'd play them for the classes. I started my school radio station. This was way back in the early 1970s.
Later I spent 20 years with a major Television & Radio network. But also attending a few major music award nominations, on my own. So I know a career driven professional when I see one..
(I bet your dad really enjoyed doing that.)
Just found your channel and I love it
You even did a collab with plasma channel who i've followed for quite a while
Your videos are going better and better
Thanks, Pedritox. My editing software can barely keep up! Haha!
Your videos are awesome! The electric current wars video was lovely... remain this path and good quality content
Smart is sexy! Thanks for another great educational video.
Thank you., awesome explanation .
My pleasure
Keep going mate, you got the potential to go big!
Subscribed..!! What can i say. You put so much effort on your videos. From graphics, to the smallest detail, to music, to comedy. Have you tried CB Radio? 🙂
I found your channel through _Plasma Channel._
Subbed...👍
Using a CB antenna on your project, while better than nothing, will pretty much tune your transmitter mainly into the CB band, which is woefully lacking an audience on a desert island, and maybe a few harmonics on either side of it at progressively lower signal strengths as you move farther and farther away from 11 meters. Any other hash that your spark gap transmitter makes will be choked out pretty much on every other frequency.
Breaking open the center loaded coil and making a "long wire" antenna out of it's wire would create static interference at higher frequencies, (shorter antenna), and with more harmonics to create a more attention getting signal across a greater number of frequencies.
It would be best to aim for the aircraft band, (108 to 136 MHz AM), as the possibility of any aircraft flying overhead would hear you on their AM frequencies as your spark gap transmissions would be more apt to open the aircraft band's AM squelch.
Most boats today use VHF FM frequencies. While the FM VHF marine band, (166 to 174 MHz), is relatively close to the aircraft band, the FM channelized bandwidth, (25 MHz per channel), and it's associated FM squelch circuit would wash out / block out your signal from ever breaking into it's receiver.
Very few ships, except for large ocean going freighters and cruise ships, at sea still use the HF SSB 6 MHz marine radios anymore due to their $4,000.00 to $6,000.00 price tag and very large, low frequency antenna compared to the $150.00 to $200.00 price tag of a good VHF FM marine radio and it's associated, much shorter, less wieldy antenna.
While the HF SSB radio would be ideal to receive a spark gap signal, being that SSB radios use a BFO, (beat frequency oscillator) to hetrodyne with the carrier free SSB signal, to be able to hear intelligible human speech rather than something akin to Donald Duck is much more appealing.
Your relatively short, "long wire" antenna made from the CB antenna's center load coil, might only make it a couple of miles out to sea at best as opposed to an aircraft's one to eight mile vertical height over head. You might also want to scare up something conductive such as a piece of wire, salt water soaked rope or what have you to connect to the spark electrode opposite from your antenna electrode. Thrown into the water or spiked into the ground, if you can find a piece of metal to use, to act as a ground plane would help to increase your range a bit. Every little bit helps.
Keep plugging away, (pun intended). Channels like yours are very beneficial and educational. Thank you for your service.
Yes I understood that but please make a video on how did that massive radio device evolve so that we now have it in our mobile phone taking a very small place .how does it fit Into a small phone and consumes so little energy but still makes it possible for long distance satellite communication? Please make a video on how modern radio device in our phones work? Also the network tower and satellite
Fantastic video 💯
God I love this channel
Must be because of the consistent upload schedule!
Amazing video, loved it
Great stuff...
Thankyou.
I'm sending a lawyer to you, he'll get you bailed out and defend you in court!
Very funny and educational video! You do a great job!
Should be an easy defense... The FCC officer was clearly incompetent; if you are in a a distressed life-threatening situation, you are entitled to use whatever means you have to call for help, including spark gap or any other kind of radio transmitter.
Very nice video editing skills!
Just don't ask how long it took to render ;)
Great video as always! It would be awsome if you could see the signal in the frecuency domain just to see how wide is the signal bandwidth!
I believe it blasts the whole spectrum all the way up to x rays.
Haha, just subscribed ❤ you remind me of "Squire" channel. I think I'll let my pupils build a radio.
I saw the professor do this on Gilligan's Island with 2 coconuts.
@@jamescollier3 Stranded on a desert island with smokin' hot Hollywood redhead and an equally bodacious farm girl, and your only realistic competition is an old fat guy and a skinny imbecile. Yeah, I wouldn't be in a hurry to fix the damned boat either.
@@xaenon Jeffrey Epstein is that you?
@@kenneth6731 Oh, look, a cheap shot from the peanut gallery! How precious. Did your mommy help you with that?
@@kenneth6731 Please....... There is a world of difference between an attraction to grown women movie stars, and an attraction to young girls. I don't understand how anyone could conflate the two.
Maybe you can kindly enlighten us why its proper to equate the two?
Spark gap xmitters generate damped waves that are very rich in harmonics all the way to the vhf and higher thus when connected to a long wire Ant can be used as a hailing xmitter to get help using damped Interupted CW
8:02 "It may not look it but i am surrounded at all 4 sides by RF shielding. Metal mesh over windows"
Well that's a snazzy prison! Good that they locked you up prophylactically.
Great video. You guys are awesome
"No, im iminocent!" Said every illegal ham ever haha
If The Professor from Gilligan's Island had watched this UA-cam video, they would have gotten home much sooner.
But ozone smells so good! 😍
I agree it is a really caristaristic smell, which you will not as easily forget. H2 and O2 also give such a great smell when you split H2O.
i wish you went into detail on how to salvage parts and what to salvage parts from and how to recognise and distinguish what parts are what n what they do n what you need. try to make one of thease out of 100% scavenged parts and see if you can "escape" brilliant video funny and educational
Guys, why are science channels so underrated? :(
I like your channel btw
Because the masses are easily entertained by flashy things and non important sh*t like popmusic and don't want to put in the effort to learn something?
Good going
love this video!!
Thanks :)
I was watching a how-to-survive-horror-movie-trap video for the movie Cube and this knowledge was probably more important than math in the movie 😄
Cube is an underrated movie, nice to hear ppl are still enjoying it :)
Awesome!
Wow awesome idea🤘🤘🤘🤘
Spark gap xmitters are now illegal bec the signal is very rich in harmonics that is very broad accross the entire radio spectrum, LF through HF and higher... spark gap xmitters emit damped waves, how ever in extreme emergency situations one benefit of being rich in harmonics is when used to send distress signals your signal stands a very good chance of getting heard because of sever RFI it will cause through out the Bands of frequencies used by all radio services, (this is the main reason why such xmitters are now illegal) but you have to knw how to send SOS in morse code, rescue responders will know that you are in distress some where out there in the vast pacific if you knw how to send this three morse characters.
How long have you been a ham?
It was actually Tesla that invented the radio, Marconi copied Tesla and patented his design before Tesla but Tesla was the original inventor.

As a man stuck on an island, thank you.
That was great! Funny as hell. Beats watching some angry old guy.
love this video !!!!!
The Video is good, even if acting is not your strong suit, it's still very good, And the information was even better, I did find myself distracted at times, by throwback to childhood, due to a little resemblance of Elmer Fudd in some of your words lol Two Thumbs up if a could!
I like the looooong yellow cord attached to the tools. Hard lessons learned?
Mrs Richards: "I paid for a room with a view !"
Basil: (pointing to the lovely view) "That is Torquay, Madam ."
Mrs Richards: "It's not good enough!"
Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window ? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..."
Mrs Richards: "Don't be silly! I expect to be able to see the sea!"
Basil: "You can see the sea, it's over there between the land and the sky."
Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction."
Basil: "Why?! Because Krakatoa's not erupting at the moment ?"
OMG ! Right at the time I was ready to FF. You did a FF.
You're welcome ;)
...Yes, but how do I make a primitive radio transmitter?
If I were on an uninhabited island, rare as they are, recalling this video would leave me only slightly better off, since IMO many of the practical details are omitted.
100 feet isn't much; what does it take to make it detectable for planes passing overhead? How much energy should I be pumping into it?
What angle should the antenna be at? How do I adjust the antenna to the length with the best resonance? Would putting in a reflector improve things?
Ships still to this day use spark gap radios for emergencies if I recall - it's not outside the realm of possibility.
As per practicality, I was just trying to make an interesting video; it's not practical. Making a signal fire is practical.
I like your setup
Funny and informative.
