i cringe every time you say master and slave
I believe the key purpose is not the emission of the high frequencies to the air, but rather transferring by the line... the ferrite core elliminates any hf entering the device from the line snd/or exitting of hf from device to the line
Nice work !!!!
I really like your technique for finding the positive, test for the noise filtering capacitors as they will show as a temporary short as they charge by the ohm meter 😉
I don't know what to say...Ron looks like a logger. He actually looks like a fired employee from an unlicensed logging company that illegally clears up forests.
Can I use any diode?
I used a regular diode with forward voltage 0.7v
That's why we should never use cheap (chn*) batteries. My previous comment got deltd.. automatically.
That's why we should never use cheap xhines batteries.
For what the M2 key is?
One mosfet switch is for charging, another mosfet switch is for discharging (work mode).
@@RonMattino But they are in series 😳
Thank so much . I enjoyed your presentation.
Crazy ! Using a computer ( android smart-phone ) to learn how a computer works.
But the metal thingy tube was wrap by wire? The wire is usually pass thru inside originally So you did not show the actual scenario. You cheated us
Not always, sometimes it is wrapped 2x.
@@RonMattino do the test correctly LIAR
This a great channel
So the output signal current source is fed from the enable node

Extremely perfect explanation Wowww thanks sir!!!!
Is it not your video. This video from Major Tom Workshop
One of the best videos ive came across explaining cpu, moms, and rams
I wonder how long it would last before dying
It won't last long, but the idea is to extract texts or images from an old phone if you need them.
@@RonMattino or if we have DC DC step down converter then we can use it indefinitely via any adaptor
So... can you use any resistor do fool the phone and use an external power supply? I have two old Nokia N-Gages with dead batteries, it would be nice having them powering on again with this method.
No, not any resistor. You have to use the same value as the original battery. If you still have those batteries, you can use a multimeter to measure resistance between the negative and middle terminal, and then use the same value resistor on your phone. But as far as I remember, Nokias use a resistor something around 70k.
@RonMattino the batteries are dead but I guess I still have them, nice tip, thanks!
This video is INSANELY salty.. what in the world? Here is a breakdown of every single minute of crazy things you have said in this video up until I couldn't take anymore BS and it was not productive so I stopped watching. Bro, DID YOU JUST CALL HIM OUT FOR SAYING BBS SYSTEM? Because the S in BBS stands for system? BBS System: "Bulletin Board System System". PIN Number: "Personal Identification Number Number". ATM Machine: "Automated Teller Machine Machine". HIV Virus: "Human Immunodeficiency Virus Virus". LCD Display: "Liquid Crystal Display Display". GPS System: "Global Positioning System System". ISBN Number: "International Standard Book Number Number". RIP in peace: "Rest in Peace in peace". AC Current: "Alternating Current Current". DC Current: "Direct Current Current". Did you just say ACOUSTIC MODELS ARE ONLY USED UNDERWATER?? Did you honestly google what an acoustic modem is? It's used in a freaking TELEPHONE.. bruh. Ok, this is crazy. It was not a term he said out of nowhere.. And I see comments of people saying you threw shade at Cobol and Fortran on this video?? What! Fortran outdated for 80s?? How did you think we went to the moon bruh? How did you think the integer system that we used, to go to the moon came about? hAcKiNg Is MoStLy AsSemBly.... yea, if you have a serial cable conneted directly on the board. Not from 1000s of miles away from the server.. WHAT! Learning assembly is not gonna let you hack into any network systems bud.. Also if you know Fortran, you MUST know assembly really well. I think The hacker mentions that in his video as well. And what pascal? Pascal is for people who can't code and need safety and abstractions... Did you just completely lie about what reverse engineering is? How do you think, brother, that, so many of x86 stuff was ported over to ARM? They had access to the schematics of the chips? aCtuAlLy "building a chip programmer device is a big deal". Any competent programmer without any degree can do this following some random engineering youtuber on youtube, I DID THIS MYSELF! no degree required.. And you can't be referring to that time, since he did not mention doing that. Brother you got the hole mining stage thing too wrong too... long before using software installed on normal PCs were popular or dedicated GPUs were used. There were special mining computers.. this is what a friend of mine used back in around 2012 or before that. I do however with your take on the backdoor banking shit he said, that made ABSOLUTELY NO sense, so that was the only good point you raised so far that I understood. Again, you said a bunch of lies about what web servers and servers are and their functions. Any programming language can open a socket connection open on any port and can be used for WEB COMMUNICATION, http and https ports are popular ports for the browser to grab HTML. Web is beyond HTML, it's not through popular ports that an attack is made usually, brother come on. No actual server running a nix OS will have random ports open.. you can't be a network administrator if you can't manage basic firewall.. There is no way anything important is hacked over randomly opened port LMAO. "You don't run them", bro you are literally trying to pick up straws here.. like how salty does someone have to be man.. It is perfectly fine to say "Web server running vulnerable ports", someone who understands computers will understand what this means, what in the world bruh? Anyone who works on the linux kernel networking subsystem, which are thousands of people, quality as a hacker, according to your definition.
The first software used to mine Bitcoin (2009) ran on PC and was called Bitcoin-Qt (later known as Bitcoin Core). Then, as hash rate grew, Bitcoin was mined on GPU rigs and later on (and up to this day) on ASICs. ASIC chips were manufactured by Bitmain and MicroBT and installed in dedicated mining machines also produced and sold by these companies. So, what was he really trying to say? That he programmed ASIC chips? Or built a machine that used them? That's very unlikely. I've never heard about anyone building ASIC machines from scratch. Super computer, eh? The terminology he uses is not professional, it's very mainstream. It also indicates he knows very little about mining.
@RonMattino I understand he used mainstream terms, which are not technically correct, but he was explaining things to a wide audience. Also ASIC miners were around since the end of 2012, a friend of mine had one in 2013.
Gummo definitely used this video to get some publicity to get more celebrity clients. But none of the things he talked about can actually be disputed, I feel like most of ya'll just hating on him because he was years ahead of everyone else at the time. Literally NOTHING technical he talked about can be disputed. I know a guy just liked him, back in around 2012 actually that bought one of the first mining rigs and was running it to generate around 40~ish bitcoins. And he sold almost all of it for half the price cuz our government takes huge tax on recieving payment on USD. When I was around 3 years old, back in around 2003 or 2, my mom used to fucking cut off the dsl cable going to the telephone booth, extend it, use a 6 pin crimper to crimp the cable and get internet on my computer, albeit, extremely slow. So like, these things happen, a lot of things happen back int the time. Nothing about gummo can actually be disputed, just accpet it guys.
You don't use mining rigs to mine Bitcoin. Bitcoin is mined on asics. Mining rigs (that contained video cards) were used for mining Ethereum mostly, and some other less popular coins.
Every phone has its polarity marked. Unmarked polarity is a rare occurrence.
Polarity is always marked on the battery, not the phone. And if you don't have the battery, there's no other way of finding it out.
Not the "simplest" explanation and the example is kinda unintuitive as it is pretty useless: you can achieve the same result by connecting the switch in series to the bulb and ditch the transistor.
Connect the switch in parallel to the bulb? You'll short your power supply then. ;) What do you mean?
@@RonMattino In series*
Which type of diode should we use? Is there a full version of this video?
Maybe this ua-cam.com/video/Sb4aVHoeo90/v-deo.html
@@RonMattino thanks. I failed to find a replacement battery to revive my old Samsung phone. I've been looking for an alternative solution. Hoping this does the trick
I will try this to revive my old phone
Excuse does diode stepdown voltage.
It has voltage drop
A ~720mV voltage drop
please fix the audio, your ‘s’ is very sharp and makes the vid nearly unwatchable
Gotta take care of this, thanks.
@@RonMattino thanks a lot, it is a great vid even with the sharp ‘s’ es but it can become even greater
0:41 V=IR OR I=V/R What does U stands for ? 😮
U is the same as V :)
Are the suppressors also called transorbs or that's another component? Also, they seem to work like two zeners connected face-to-face.
very informative and useful video. Thanks.
This is what I needed to know about the third pin on the battery. Now I cleared about this doubt. Very informative video. Thanks a lot.
Short answer: Temperature
very awesome and amazing 👍
Thanks Ron
So how many USB-Acan I put on a cat six shielded cable?
Resistance of a thermistor is not proportional to temperature. It is inversely proportional.
There are both types, PTC and NTC
@@gsilva220 Traditionally the thermistor is an NTC device because it is made from a non doped semiconductor and the conductivity increases as the temperature increases because more electrons are given energy and are kicked up from the valence band to the conduction band. PTC thermistors, often referred to as silistors, arise as a result of extrinsically doping a piece of semiconductor material.
Inversely proportional is a type of proportional relationship 🥂
@@heavenlymonkey They are in fact complete inverses of each other.
this video is fucking awsome, now I understand why cpus are called 8 bit or 32 bit etc. amazing, how fascinating the world of it is
Can this method be used to connect a xbox one/ps4 controller in a 15m run from said xbox one/ps4 to another room?. Ive ran a 15m hdmi run in the same direction for satellite tv. Thought why not try using my roll of ethernet creating a usb run to control my Xbox or ps4 connected to that HDMI run. Thanks
For 15m I would use CAT6 FTP cable.
Im a repair tech and every short vids like this i like and subscribe :)
Can we make a usb3.0 cable like this?
Not really. Or at least, so far. USB3 uses shielded pairs with an additional ground wire per every pair. FTP cable does not have that.
Why does your voice sound autotuned?
Maybe I got Autotune installed in my head? ;)
I simulated this circuit. The input signal must be < 0.5Vp, otherwise the diode will be forced to turn on at negative cycle.
Then you are missing some parameters
Simulation isn't always accurate.
No I cant guess the burpose of this circuit
Perfect illustration of how it could work in an 8-bit microprocessor interacting with memory and indicator LEDs.
Now hand it over to eletrodoom guy😂😂
