- ►WHAT IS THIS
Before such breakthroughs as AM radio, radios would rely on a binary sort of transmission called Morse Code. This signal was send as radio noise (1) or lack thereof (0).
With the help of Plasma Channel, we recreate a spark gap radio similar to how its inventor, Marconi, would have made it over 100 years ago.
DISCLAIMER: In most places in the world, it is not allowed to transmit using a spark gap. We informed the FCC and conducted our work indoors to not affect the airwaves.

Absolutely brilliant work, Blueprint! Your use of comedy mixed with information honestly is what the masses need.
Plasma Channel.... I’m a subscriber
Blueprint could not have said it better which suggests that you are saying it for Blueprint. Maybe just another channel shill -- just what the masses need, more bullshit for TH-cam money.
Maybe you could expand on this with a better animation showing oscilation of force (field) lines, and demonstrating the kind of signal a SS "sparkless" Tesla secondary would produce ? Flybackless /watch?v=X5sCM2q6PXU
Nice colab. I really enjoyed the content. You're both serious scientists, but you're both pretty good entertainers. Hey, I got an hours worth of high quality "Edutainment" (yeah, like that's still a word). Like I said, you're facts are accurate (Except that part about the hazards of extremely low concentrations of ozone). But I digress. as a sacrifice on behalf of you both to the almighty algorithm you both get a like and a sub. Of course now that subscriptions play a role in monetization, and everyone implores you to do so, notifications from TH-cam are now completely meaningless. I'm guessing they factored that in.

This is why shipboard radio operators in the early days were often nicknamed “Sparks” or “Sparky.”
Related to the subject of radio the building on a ship that housed the transmission and reception equipment was called a "radio shack".
As a ham radio operator, I thought this video was amazing! Not only does it explain antennas very well, but how aincient radios worked in general. Shame channels like these don't have more subs.
Thank you!
Special thanks to Plasma Channel who did a great job building and testing his transmitter! Seriously, you should check him out if you have not.
P.S. Quick note to all, feel free to join the Blueprint Discord server! discord.gg/kUhsU4p
Keep up the good work Dude 👍
I luv you bro
See if it will be more cooperative while building this flybackless SSTC /watch?v=X5sCM2q6PXU
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? Pun intended.
It's a shame your channel doesn't have more subs. Keep going!
I have no intention of stopping. Thanks LeLyfa!

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.
Just found this channel. Very entertaining and educational... excellent work. Subbed
It's amazing how you integrate your sense of humour with teaching this sort of stuff. Great video.
This guy deserves a million subs.
Great work putting this video together, thank you for sharing!
I just found this channel and have been watching it all weekend. Please make more videos.
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
I didn't see this video before. Excellent editing as always!
One minute in and i was compelled to give a like. I genuinely just wanted to learn something but your videos always make me laugh as an added bonus
Into Wishin, you are appreciated!
Thank you very much. I have just been shipwrecked on a desert island.
Thanks to your TH-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.
The monkey part had me laugh out loud! Bro, I've worked with electronics my whole life and never understood it the way you broke it down. Thanks man!
We need more channels like this
Just found your channel and I love it
You even did a collab with plasma channel who i've followed for quite a while
I'm learning a lot during this quarantine. Thanks!!
So funny and informative as well. good job guys.
best video yet! loved it
I love your humor and information! Well done man!
Yo, thanks man
He is so smart and will succeed at everything he does.
My heart went into free oscillation when he touched the flyback...
Why am I only seeing these videos now “March 2020” these are excellent . Well done young man
Thank you, sir
I did this experiment when i was 14 or so. Now i am 63, but still like building cristal and tube radio's!
Keep going mate, you got the potential to go big!
This is great, no real idea how radio works, read about spark gaps and coherers but never saw one in action until this video.
Quite enjoyable mate! Learned a lot i did. Thanks, Cheers!
nice pair-up. great presentation!
I found your channel through _Plasma Channel._

I am very impressed with your talent, I pray to learn and I know through you that the work is very good 🎉
Thank you., awesome explanation .
My pleasure
Fantastic video 💯
Entertaining and educational video. Thanks.
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.)
Amazing video, loved it
Damn, the greenscreen in the beginning looks terrific. The lighting is pretty convincing
Didn't even realize until I read this comment
This was hilarious! Another great and informative video from BLUEPRINT.
Thank you :)
how do you change the frequency, so you don't interrupt used channels
Great video. You guys are awesome
love this video !!!!!
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.
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.
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 TH-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).

i want to know how to connect the battery part ,if you want to creat a transmiter
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.
Josss bro...really great videos😍😍
Thanks bro
interesting, the signal will allow the LED to continue to light after the switch is closed on the transmitter. Is there a cap already charged to begin with ? Have you tried to have both ends of the bolts of your coherer driven into the earth and see if this works just as well. I have tried something similar and the earth will carry the signal to enable the circuit to be closed.
I love this guy!
I like your setup
LOL !! I love this video!!
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.
Basicly an audio modulated tesla coil then
Haha, just subscribed ❤ you remind me of "Squire" channel. I think I'll let my pupils build a radio.
God I love this channel
Must be because of the consistent upload schedule!

hydraulic press channel music :) I love those guys
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.
Fortunately EMERGENCY SITUATIONS have legal allowances for operating equipment not otherwise allowed.
Such as, using a spark gap radio to signal help.
Or if you do not have a ham radio license, you may use ham radio equipment to notify others of an emergency situation... IF NO OTHER PRACTICAL MEANS EXIST.
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".
KU KU KU
Now THIS makes me excited!!!
I have that same spark generator. Is the ozone it creates actually dangerous?
Also, I created a spark gap generator and detector based on videos by electroboom.... if I use two dipoles it does not work... if I use two monoples and connect the grounds together (with a wire) it "works" (the led lights up when I create the spark.
Do I need the inductor and cap on the transmitter side? Why does it not seem to work with dipole antenna? Is it working when I use a wire as a common ground or is it just using the wire to light the led?
Smart is sexy! Thanks for another great educational video.
Cool wheelie🌿🤗🚜
And for receiver you said various capacitor etc can specify pls
Funny and informative.
bloop rent is amazing-thank you for years of helping an idiot at least begin to understand these concepts
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.
OMG ! Right at the time I was ready to FF. You did a FF.
You're welcome ;)
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
what do you use as spark gap electrodes? it look some thing like horn
Good going
Thank you
Soooo can Magneto listen and communicate on radiowaves ?
And is the radio the best thing to have when under a pile of debris after an earthquake?
Magneto is awesome
Yes he can; his powers/abilities are severely downplayed/underrated/unknown.
...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.
Hi! Quick question, at the end of the video when you said "you'll be able to send a signal for miles" is that a realistic estimate? Or was that just a dramatization for the sake of entertainment? Thanks!!!
Miles is accurate. (Well, technically I was just holding a prop - it didn't really transmit).
Mariners used spark gap radios all the way up into the 80'a for emergency reasons. They could be heard for roughly 10 miles around.
how do you make an emergency transmitter using the engine coil & spark plug? drawing please
What? The coheared iron filings keep producing power to the led ??
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?
nice job
"No, im iminocent!" Said every illegal ham ever haha
"Monkey save me!" Epic!!
this guy is exactly like howard wolowitz from big bang theory with less sarcastic, it is a complement dude
Comparing anyone to any big bang theory character is never a compliment.
Can you show us how to make the antenna or the receiver and make sure it's a part 2 okay
