Cell Phone Glitch

 by NapoleanDynamite
This is a glitch me and my brother found out. It is pretty dang loud to, so be prepared. It also kinda sounds like a Ring Wraith from Lord of the Rings. And all it requires is two cell phones!(We did it with a RAZR and a Samsung Sync, it might now work with other phones.)

um yeah that is a good way to blow the the speaker in the phones and why would you want to do that any ways

You don't need to link two lines together. Just put both phones on speaker phone. Call one phone from the other. Put the mic part of one phone, to the speaker of the other (kind of like a phone in the 69 position lol), and make noise or clank the two cell phones together, and it will begin to make noise, quite annoying, did this many times last year in my dorm.

i did the same thing but i used two house fones on the same line so it dident waste minits

Ah. Well, we have 1400 minutes on hour plan for each month, plus its free Verizon to Verizon, so it doesn't waste any of our minutes.

Verizon is bad because att is good. Verizon has a stalking bald guy. "My phone is broken!" "We've got you covered!" "Who the hell are you?"

If at&t was bad, would Verizon be good? How are they connected? I don't mean to be rude, I'm just curious.
Colonel88 in reply to ducksarewetNov 8, 2009. 6:34 AM
No, because both are major phone companies. Ow my head hurts now...

NapoleanDynamite--

Man keep on discovering stuff! You done good! If you keep up looking for strange things that happen when you do your experiments, you will have the chance to gain more knowledge then you could possibly believe. Take each 'new' experiment you do, think hard on it, and find the truth behind it- in other words, what makes it 'tick', or work. That is the important thing to do- learn! Don't argue about it, learn from it. You done good. Oh, by the way, brothers always remain stupid, until you are 30 or so, maybe 40...

This is an issue with cheap pa systems. if you keep the microphone too close to the speaker, you get a squeal.

havn't you ever played with walkie-talkies?
nature223 says: Oct 12, 2008. 3:47 AM
it's called FEEDBACK
lamboboy732 in reply to nature223Mar 13, 2010. 5:52 PM
Some people arent smart enough to know that. To these certian people anything unusual in life is a "glitch". lol

Uh, is this just some 10 y/o kid learning about feedback?
bobhill125 says: Mar 5, 2009. 7:06 PM
i no how to did this and im only ten i leared how wen i was 9
lilpepsikraker in reply to bobhill125Jan 7, 2010. 12:32 PM
I also notice you cannot spell, and have a lack of simple grammar.

Hey man, back off, he's only ten.  lol

yeah. ive done it with my home phone. just put 2 on speaker, and bring them close to eachother. this can also be done with a mic. i have a piano with a mic. i put the mic up to the speaker of the piano (i mean keyboard) you get lound noise, especially when its on full blast!

Oh wow, I made feedback thanks to this DIY! And whats the deal with this kid "Glitcher"? Seems like he has something to prove but at this point I have no idea what that is. Fighting for the science behind feedback doesnt really validate my life in any way. Sucks for me I guess.
disturbedreaper says: Nov 2, 2008. 5:14 PM
i dont think you need to link the calls you only need to call one person and put the phones close together

Ok, lets get this strait...feedback is a CONSTANT high pitched noise you get when you get two phones together IN THE SAME ROOM.This contains WAVES OF LOW OR HIGH PITCHED FREQUENCIES on both phones. notice the difference. and don't post before you try it please.

you can be a million miles apart...if a phone is set for "speakerphone' it can cause feedback to itself. That's what you are hearing 100 miles apart: FEEDBACK. Listen kids, trust the old timers. We know.
Father Christmas in reply to xrobevansxAug 25, 2008. 6:23 PM
it doesnt work like that. the phone is specifically programmed for the microphone to reject the sound the speaker produces to prevent circulating audio patterns. otherwise it wouldnt matter how the phone was being used. if it was set to speaker and the there was and exchange of audion information on both ends, there would be a plethura of circulating signals identical to eachother.
hoihoi151 in reply to Father ChristmasJan 25, 2009. 11:51 PM
some very expensive phones have feed back protection. this means that if the phone detects a high pitch loud noise it shuts the mic and spkr off. we use the same principle at our concerts with noise limiters. wen we hire equipment they put noise limiters in the sends so it doesnt blow the spkr. hehe. little do they know if u attach a mic to the limiter and run the mic bhind the stage where there is little noise the limiter is inefective
xrobevansx in reply to Father ChristmasAug 25, 2008. 7:41 PM
Really? Where do you get your information? How does the phone get "programmed" to do this? Typically the speaker and mic are opposite so the speaker would have to be extra loud for the feedback to occur....in which case you get FEEDBACK. There is no magical "programming" of which you speak, sorry.
glitcher in reply to xrobevansxSep 30, 2008. 6:38 PM
The speaker can pick up a small wave of audio, you don't have to scream in the phone for the other person on the line to hear you
glitcher in reply to xrobevansxAug 26, 2008. 3:02 PM
if that is so then why do the manufacturers put speakerphone in? why when all other phones get put on speakerphone it doesnt do that? your thinking is like a child's, just because we say so you say no. if you think about the "solution" then you can find the problems in your hypothesis. you must have not been in college at all since you take programming do lightly...
xrobevansx in reply to glitcherAug 26, 2008. 4:01 PM
Speakerphones aren't usually full duplex because of FEEDBACK. Ever notice you can't really talk while the other person is talking? That's called half-duplex. Some are full duplex I am sure. Then, if the speaker was loud enough and the mic was sensitive enough, you'd get FEEDBACK. I went to college, got a degree and taught high school. The burden of proof is on YOU. I (we...the rest of us that are right) know I am right I don't need to be validated by you. By the way, where did you go to college and for what?
glitcher in reply to xrobevansxAug 26, 2008. 6:40 PM
MIT for comp programming. I also got a minor in physics. Where did YOU go?

Would you like to know about the simple programming languages(i.e. C#, HTML, etc...) Or would you like some pro CSS techniques? I can give you plenty of those. It is in fact what I special in. You cant expect a single man to explain all of programming even from MIT. There is to much and it would take way to long. And when YOU know what you are talking about, look ME up. You never know, I might have a spot open for you. I will give you a boatload of info on CSS if you need me to to prove myself. I'm available on weekends, and after 7 O'clock on weekdays.
xrobevansx in reply to glitcherAug 28, 2008. 4:30 AM
It is in fact what I special in Web design? Woopty doo. That's hardly "programming" You proved my point.

With your VAST experience in "programming" surely you could explain this "programming" of the magical cellphone that doesn't create feeedback (beyond the obvious half-duplexing). All of us dummies that believe in the wild and crazy "feedback" would love to be enlightened.
