How to Wiretap Phone Line with DIY Circuit 

I drew the winner of the Keysight Scope! The lucky guy is: - Luis Enrique G. S. Thanks everyone to enter the draw. FBI pays good money for your emails, HAHAHA! Just kidding, they already have all our emails...

Holy shit that lamp scared me

"Why is it that i die a little everytime you call"😂😂😂

I always love the free-floating circuits without a breadboard or PCB, adds an extra level of chaos.

Love how he didn’t want any electrical shenanigans to happen with his camera so he used a lamp to add some excitement instead😂😂 I’m so glad I found this channel again.

Circuit isn't warm...Everything looks goo- *LAMP ATTACK*

Im already a huge fan of the 'Full Bridge Rectifier'

5:31 that was the calmest "full bridge rectifier" i've ever heard from you.

Theory: When Mehdi gets shocked quite hard, he actually dies and gets replaced by one of his personalities, there is an infinite amount of Mehdi. Mehdi is love. Mehdi is life.

Jeez! Had to reupload the video. Some smart people were decoding my cellphone number from caller ID noise in the video! Anyways, feel free to post questions or comments in ElectroBOOM subreddit: www.reddit.com/r/ElectroBOOM/

One of his personalites must've threw that lamp.

1:25 "NEeeYEhHh!" 🤣

7:39 sounds like something you would here in a dank meme

"Never set a bad example" -ElectroBOOM, shortly after licking a live wire :)

I was waiting for something to blow up and then the f*cking lamp happened.

7:29 ElektroBOOM:"change the audio input to the phone line and die..." Me:"you do that in every video..."

7:43 I remember that! It was like the noise of a dial-up modem. How interesting analog communications filled with digital stuff are!

7:00 I'm pretty sure everyone was waiting for something and the lamp happened

4:56 Circuit Designing Intensifies!

0:48 has me dying laughing for weeks now.

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

*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.

When the electricity doesn't get him, his light fixtures do.

4:57 *this is quite literally how my dad plans*

"Now let's design!" *[existential crisis with funk accompaniment]*

i love the seamless blending of actual good advice with the comedy. this man is a genius.

LOL that slap to the face scared me [0:35], but had me in tears Jesus that lamp drop around 7:03 had me jump out of my chair. I swear he's out to get me

U ever had a jump scare that felt like a jolt of electricity... well me too thanks to that lamp at 7:07...

“Why is it I die a little whenever you call”.. subscribed

7:40 Dat BASSSSSSSSSSSSSSSS!!!

"Pretty harmless voltage" 0:53

Your videos are so much smoother and the effects are more complex ever since you said you were watching some SkillShare videos for video editing, it really does show progression!! Out of all of the paid promotions I see on RU-vid, you portray them in a humours, fun, yet also effective way that convinces me to actually try them! Your videos are the only ones I watch on RU-vid, that I don’t skip right passed them. Medhi, you are truly a daily routine for me, and I hope you NEVER stop absolutely loving what you do! You don’t know me, but YOU are an unfathomably important person to me.. Thanks for existing, and for being seamlessly prosperous doing it!

Wait Phone line --> Free electricity?

When you shocked your tongue, my motion light in my house turned off above me at the exact same time. Couldn’t have been timed more perfectly. And it makes a loud click when it turns off. Talk about 4D...

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.

1:22 Anyways, this DC level is pretty safe on skin *2 seconds later* NYEH! ... SH*T!

7:40 tfw the bass drops O.o

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.

You have discovered the best way to teach electronics to young people by being very funny. I have 50 years of experience in electronics and I find you very funny. This is the best way to make people love learning electronics. Trial and error. THANKS. And you are a Canadian. I am proud to be Canadian.

6:47 The Tension was immense! Suddenly lamp

THAT LAMP! GOT ME THE 2ND TIME!

R.I.P Electroboom Got killed by floor lamp Press "F" to pay respects

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.]

RU-vid needs more of this kind of content provider. Sites like TikTok, Troom Troom, and 5-Minute Crafts rot the brain.

7:06 my cat literaly jumped from my lap when this happened

4:56 when your doing math homework

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

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

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 :)

I like your community for decoding your phone number from the recording. They not only know how caller id works, they even make the effort to download the video, cut out the important part and then decode it just for fun.

7:41 what mad lad was finding his phone number with that sound like wtf

electroboom: *can finally have a video where he doesnt get hurt* lamp: *im gonna do whats called a pro gamer move.*

7:40 I'm permanently deaf now

7:40 the new XXXTENTACION song sounds great

I like this guy. He's funny, entertaining and knows his electronics.

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.

Sorry ElectroBOOM.. I just wasn't happy with the second mention of the full bridge rectifier at 5:30. It MUST be said with the usual gusto & feeling, so.. FOOOOL BRIIIDGE REEECTIFIER, ok ;)

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. :)

Love your talent with the eyebrow...cracks me up every time

Very very well done for your help with school and education

5:30 smoothest "full bridge rectifier" of history

7:04 First time i didn't expect what happened

You are doing great.👍👍😎.keep making videos .I am big fan of your informative channel.

Thnks for giving so much practical knowledge ....

Saw the reason you reuploaded the video. Really didn't know this could be done. Stay safe Great Rectifier!

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.

0:53 "Yep, yep, pretty harmless indeed"

7:52 he sounds like from a film in 80s

4:57 had to watch this part over and over. Brilliant!

7:40 I WANT THAT KIND OF HOME PHONE RINGTONE

last two days im on a marathon of your videos and in every video u giveaway those scopes. Like every keysight scope I will ever see will be from your giveaways lol

Teacher: u can’t hear electricity that’s impossible Me: 7:35

"Never set a bad example"... ...have you watched any of your other videos?

0:57 I T *H E R T Z*

Your videos make me 10x happier

bro got the same camera, nice work even after 5 years i still enjoy it

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.

@4:57 *MEHDITATION*

this chanel is gold

Human Antenna remote neural monitor video would be a life saver. Brain mapping remotely. Great piece of knowledge here thanks

"why is it that everytime you call i die a little" ahahaha xD

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.

Me: *taking a test* My stomach: 7:40

The lamp falling was great 👍. Love your content! Keep it up ☝👍

3:01 haha remembered my child hood

School giveaways sound like a great idea, that's cool

Watching ElectroBoom is like watching a good horror movie - you know that something is going to happen, but you never know what and then. It could be a capacitor imploding, everything setting on fire or a lamp falling out of nowhere

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 :)

0:40 "I plug in this phone cable..." I somehow expected that to explode

I wish there were more people who didn’t just come for the laughs even tho this is pretty funny. He explains very well

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.

7:07 IM IN TEARS!! XD

You always deliver the BOOM! Thanks

I really like the way you say 'FULL BRIDGE RECTIFIER!'

Electroboom: shocks himself over and over again His fingers: oh please have mercy on me😭

04:57 this is legit me when i am designing something

7:30 hmm let’s turn it up a bit to hear the phone line *h r b l g r b l h b r l g b* Lmao

Theoretically, you could connect a speaker and a microphone to the phone line, then add a switch to connect and disconnect the load to tap out pulses to dial out like an old rotary phone (at least in the US, pulse dialing is still supported).

You're so creative with your little inserts of humor
