Back in the day they sold televisions made like that! A dozen valves, dozens of passive components, transformers, all made by soldering components directly to each other, and to the pins of valve sockets. Sometimes they'd have a tag strip, a strip of phenolic-impregnated paper, early PCB material, with metal tags with loops on each tag, attached along either side. The tags weren't connected to each other, unless you wired them together, but usually components just spanned between them, and each other, and the valve sockets etc, flying through the air (flappin' in the breeze!) like some sort of scifi architecture! Then one day somebody invented the printed circuit board and it all got a lot more boring, though probably safer, and allowing more complex circuits to be made.

*Fun fact:* The term for the polarity of the phone line, "tip" and "ring", refers to the connectors on the switchboards operators used back before tone based switching. It doesn't mean any type of signaling, but rather it refers to the shape of the connector which is reminiscent of a quarter-inch mono channel audio jack. So it literary means the "tip" (+ side) of the audio jack and the "ring" or "sleeve" (- side) below the tip of the audio jack.
The GPO switchboard plug was more pointy than the standard 1/4" audio stereo plug to make it capable of rapid insertion and less wear. Tip and ring went to the twisted pair and sleeve to earth.

Here in the USA, The line voltage is around 48 volts when off. Ring voltage goes from 0 to 96 volts. When you pick up the hand set, the line voltage drops to around 6 volts.
@@DaiShuryoTechnus there isn't any difference really as far as I know. Old rotary phones work via pulse dialing so 10 short pulses (the clicking of the rotary) means a 0. With old systems you could literally fake this by pressing the button that hangs up the phone in a proper maner. Very difficult though but not impossible. The pulse is literally closing the circuit really fast, this video shows it with an LED: th-cam.com/video/2JlGYetRfi0/w-d-xo.html Modern phone lines work with tone dialing where a frequency is sent for each key instead of pulses.
Phone lines support classics for sure. My 70 year old Western Electric Model 302 phone still works fine. I even made a recording of its bell ringing and use it for the ringtone on my mobile phone.

Residential POTS lines are normally-open 48v D.C. circuits, the “hook” is a switch that closes the circuit which allows a dial-tone. Your particular “line” is a loop referred to as a “local loop” which terminates at a telephone switch operated by your carrier. In a business, typically you would have a PSTN telephone network that connects to a PBX that directly handles internal calls to extensions, the PBX will also have either an ATA that converts analog to SIP and connects back to an IPPBX in a VoIP system in a hybrid network or to a 23 channel PRI, usually a T1 interface back to your carrier for external calls. From that point on the infrastructure will remain the same as a residential one except businesses typically have multiple lines/subsequent numbers. The infrastructure within the walls of your company will typically fed by a 25 or 50 pair whip punched down into one or several 66 block(s), or 110 block(s) depending on the architecture of the network. Those blocks can be daisy chained/piggy backed together or be fed directly into another 25 or 50 pair amphenol whip connected to a voice gateway and out to a provider. T1 PRIs are significant because they are 24 channel circuits (in North America) at 1.544mbps bandwidth that operate at a set rate (hence PRI “primary rate interface”) controlled by the DS0 or framing channel which allows the line to operate at a set and predictable rate (enabling a clear voice call)....could go on for days
I'm pretty sure you already know that but I'm going to say it anyway: The camera outputs DC voltage, because it was designed to support electret microphones. :)
I was actually studying this this semester in my uni and we had some lab classes about this but still I find this video very educative given the way you approach this. Thank you for existing. Can't wait for more videos of yours :)
ElectroBOOM, the DC voltage you see from the camera as soon as you start recording is the supply voltage for electret microphone capsules. It is commonly called "plug-in power" and is present on the microphone input of almost all consumer devices since the 80s, like walkmans, PC soundcards and laptops, cameras, etc.
The DC output on the camera's input could be to power electret mics. I recently saw a video where someone found some of their cameras did, and some didn't, and none of them documented that being the case.
It's probably not for professional condenser mics which take 48V nominal (usually work from 9V or 12V and up, so much of the cheaper phantom host gear doesn't bother with full nominal voltage), but for electret capsules, which take something like 2-5V via a couple kOhm current limiting resistor. It might be conditional, i.e. they might be measuring the impedance of the microphone, but you normally expect electret mics to be directly supported by cameras.
Makes sense, its been ages since i've used a camera, either way it's to power active (non-dynamic) mics. I remember there being a phantom setting on the Canon SLII but again, this was ages ago and likely things have changed a lot toward lower voltage active mics.

Hi. Len from Ontario, Canada. I know that I am few years behind but I must say that I love your videos and especially your very generous giveaways to schools, etc. Thank you. [a thought just occurred to me- I would add a cap to the ground connection of your circuit to absolutely disconnect any DC component from the phone line to the camera or better still a transformer.]
I have very little knowledge of electronics but I love watching your videos, but in order to understand all of the components I need to rewatch the basics every ~ 6 months, so explaining each component on these small circuits can actually be veeeery good for you on a long run, your videos probably will be used in schools worldwide. Also you can just add a layer of text on the video, just copy paste each time you edit for the circuit component you are talking about, or just ELI5 all of the circuit. I am IT engineer and love your videos, I know you prepare for them but honestly they are way more entertaining to people that learned this stuff in school.
Just added you to my Patreon list, really enjoy your videos. If you ever want to look inside a chip, just give me a shout. I am the lab manager for a small semiconductor failure analysis lab in Texas. We look at things blown up all the time, but at the micron level. Keep up the good work.
Bill James Wow, that sounds quite interesting, have you ever considered starting your own youtube channel? I'm pretty sure it could be very informative if you would share some of your knowledge :)
I used to work for BT here in the UK remember crawling along the top of cable tray and puting my hand on a cut cable with ring tone on it leaped up after getting a shock nearly knocked my self out on the ceiling which was only about 3 feet above the cable tray!!
Haha! When I was a kid i wired an extension to my mom's sewing room so that we could have computer with email (mom said Internet was the devil.) Everything was fine until someone called us and I got surprised by 160 volts:P Of course I didn't realize exactly why this had happened until I went to the library the next day to search Altavista. My efforts were rewarded by discovering a problem with Juno's ad proxy software where there was a particular ad that gave me unrestricted Internet access at home, hence I learned being electrocuted is a good thing :)
It least I know I'm not the only person who thought it was a good idea to enclose my whole circuit in hot glue as quick, cheap enclosure. For a circuit like this, I would make it thinner so the whole thing fits in a large heat shrink tube, fill the tube with hot glue, then heat shrink the tube to squeeze out the excess glue to make a sleek, compact enclosure.
I like the look of those keysight 'scopes, but just can't afford one right now, but that said, there should be plenty of older 'scopes on eBay etc. I remember building a similar circuit many years ago, but never really got it to work properly. I seem to recall that it prevented anyone from making outgoing calls - Not a bad result really, considering that I was the one paying the phone bill!
He had to mute out the original sound. The individual tones, like when dialing on a keypad, all have their own unique sound. That’s how automated phone systems can do stuff like “Press a number to be transferred to X department”. So someone was just recording the original dialing tones and then feeding them through an online decoder
After that sound you heard there were rapidly changing number tones (like the ones you hear when you press the numbers when dialing) in the muted part. That's how landline phones are able to show you who's calling. That tone sequence is the Caller ID, and people were decoding it manually.
It can't be disconnected. It's a live 48V DC supply direct from the telephone exchange which can't be felt at all. I don't know what the ringing pulse is, but it's enough to generate an F word followed by laughter. Obviously when working on our 240V AC mains supply, I always disconnect at the consumer unit, then double check no wires are live before touching them.
i was connecting a phone ext socket to some stranded cable, while I was working on the live line, there was a arc flash but I managed to get it working without damaging any of mine or bts equipment, scared me though
I used to do this by just wiring the ring and tip wire directly into a mic port on a recording device. No circuit or resistor just straight in. Always worked fine for me.
Nice video, but If I was about to design something that I want to make sure don't destroy my "camera", I would use a Optocoupler to separate the external source !
This guy is awesome. It makes my head hurt Everytime I watch a video but the guy is a genius. Makes everything look so easy and I would have no idea where to even begin lol
Very cool! I don't think young adults know what a phone line is anymore. Also, I think capacitors hide damage pretty well. The ones I abused seem to only show leakage problems when I put them in series.

In any case, I'd add a cap to both ends of the pairs. If the low side of the circuit drops down to -45V, you are in for a super good time.
Probably phantom power for condenser mics. Pretty common in pro audio. it would be 48V if so.

2:53 imagine if the government wanted to wiretap mehdi's phone 🤣
Ikr😂

Does anyone have the number sounds of 7:42?
7:40 the new XXXTENTACION song sounds great
Ik
as a music producer, the first thing I thought when I heard that was "damn that sounds filthy :D"
4:57 had to watch this part over and over. Brilliant!
That's what companies expect their engineers to do when they hire them haha
0:48 has me dying laughing for weeks now.
Just like that other video where he says “and you can see, there is no current across these wire when I touch i… *ZAP* Oh sUGAR!”
He literally awakened a new cat boy personality lmao
7:38
Ah yes. 48 volts. Fuckin hilarious
@@WilburJaywrightWhat video was that?
Just added you to my Patreon list, really enjoy your videos. If you ever want to look inside a chip, just give me a shout. I am the lab manager for a small semiconductor failure analysis lab in Texas. We look at things blown up all the time, but at the micron level. Keep up the good work.
Bill James Wow, that sounds quite interesting, have you ever considered starting your own youtube channel? I'm pretty sure it could be very informative if you would share some of your knowledge :)
I always inserted a small 1:1 transformer to eliminate potential for ground faults. That way the signal can be used as in input to any device.
5:30 smoothest "full bridge rectifier" of history
He has made a history.
7:06 my cat literaly jumped from my lap when this happened
lol
I like this guy. He's funny, entertaining and knows his electronics.
U ever had a jump scare that felt like a jolt of electricity... well me too thanks to that lamp at 7:07...
That lamp bombed on his ass🤣🤣🤣

I used to work for BT here in the UK remember crawling along the top of cable tray and puting my hand on a cut cable with ring tone on it leaped up after getting a shock nearly knocked my self out on the ceiling which was only about 3 feet above the cable tray!!
TH-cam needs more of this kind of content provider.
Sites like TikTok, Troom Troom, and 5-Minute Crafts rot the brain.

7:40 I WANT THAT KIND OF HOME PHONE RINGTONE
It's the Voltage to ring the Bells on a Rotary phone and early Touch Tone Phone's
Ring the bell rem8x with seesaw@@doramilitiakatiemelody1875
7:34 this still cracks me up to this day
Haha! When I was a kid i wired an extension to my mom's sewing room so that we could have computer with email (mom said Internet was the devil.) Everything was fine until someone called us and I got surprised by 160 volts:P Of course I didn't realize exactly why this had happened until I went to the library the next day to search Altavista.
My efforts were rewarded by discovering a problem with Juno's ad proxy software where there was a particular ad that gave me unrestricted Internet access at home, hence I learned being electrocuted is a good thing :)
KatjaPurrs that’s cool
did a lamp hit you to?
The lamp falling was great 👍. Love your content! Keep it up ☝👍
bro got the same camera, nice work even after 5 years i still enjoy it
@4:57 *MEHDITATION*

0:54 Phone lines into tongue.. I don't know if it's good or not.
Good video! Keep it up.
4:54 Seems im not the only one.
It least I know I'm not the only person who thought it was a good idea to enclose my whole circuit in hot glue as quick, cheap enclosure. For a circuit like this, I would make it thinner so the whole thing fits in a large heat shrink tube, fill the tube with hot glue, then heat shrink the tube to squeeze out the excess glue to make a sleek, compact enclosure.
ElectroBOOM: *Makes good circuit from the first try* "Everything is fine"
Lamp: I am gonna end this man's whole career.
7:06 This is the first time I see a Deus Ex Machina event that causes problem instead of solving it.
Wow a classicist in electroboom Channel? Hi mate :)
1:22 Anyways, this DC level is pretty safe on skin
*2 seconds later*
NYEH! ... SH*T!
I like the look of those keysight 'scopes, but just can't afford one right now, but that said, there should be plenty of older 'scopes on eBay etc.
I remember building a similar circuit many years ago, but never really got it to work properly. I seem to recall that it prevented anyone from making outgoing calls - Not a bad result really, considering that I was the one paying the phone bill!
That lamp scared the living shit out of me
7:41 what mad lad was finding his phone number with that sound like wtf
He had to mute out the original sound. The individual tones, like when dialing on a keypad, all have their own unique sound. That’s how automated phone systems can do stuff like “Press a number to be transferred to X department”. So someone was just recording the original dialing tones and then feeding them through an online decoder
ElectroBASS BOOST
BRRRRRRR
After that sound you heard there were rapidly changing number tones (like the ones you hear when you press the numbers when dialing) in the muted part. That's how landline phones are able to show you who's calling. That tone sequence is the Caller ID, and people were decoding it manually.
I really like the way you say 'FULL BRIDGE RECTIFIER!'
7:08 scared the shit out o me.
I got caught like that. I was wiring up an extension second phone. Someone phoned me while I was connecting the wires and I got zapped.
It can't be disconnected. It's a live 48V DC supply direct from the telephone exchange which can't be felt at all. I don't know what the ringing pulse is, but it's enough to generate an F word followed by laughter. Obviously when working on our 240V AC mains supply, I always disconnect at the consumer unit, then double check no wires are live before touching them.
Same here. Was wiring an extension socket under a counter when someone called. Got zapped and banged my head on the underside of the counter.
ha ha. That's worse than mine. It's not the voltage that hurts, just the surprise.
i was connecting a phone ext socket to some stranded cable, while I was working on the live line, there was a arc flash but I managed to get it working without damaging any of mine or bts equipment, scared me though
derekcolman 😂lol
I used to do this by just wiring the ring and tip wire directly into a mic port on a recording device. No circuit or resistor just straight in. Always worked fine for me.
You always deliver the BOOM! Thanks
6:47 The Tension was immense! Suddenly lamp
Nice video, but If I was about to design something that I want to make sure don't destroy my "camera", I would use a Optocoupler to separate the external source !

This guy is awesome. It makes my head hurt Everytime I watch a video but the guy is a genius. Makes everything look so easy and I would have no idea where to even begin lol
you're the most funniest engineer alive😂
0:40 "I plug in this phone cable..."
I somehow expected that to explode
Slipy61 me to
Very cool! I don't think young adults know what a phone line is anymore. Also, I think capacitors hide damage pretty well. The ones I abused seem to only show leakage problems when I put them in series.
The guy can sing out the Mission Impossible theme.
The guy can wire-tap phones.
Ladies and gentlemen, we have the newest member of IMF!!😂😂😂
Keep it up(In fact, when have you not😂😂😂.Your videos are full of advises, knowledge of electronics (or of other stuff) and comedy!)👍👍👍
International Monetary Fund??
CircaSriYak I don't know if this is sarcasm, but in the movieverse IMF stands for Impossible Missions Force.
Yeah! I know that.
I was trying to make a little joke! (not sarcasm).
I believe that as always I have failed in that attempt.
🤣🤣 I was referring to Impossible Mission Force!!
It seems to me that no one understood the joke!!
By your logic IMF could stand for....
