Cell Phone Glitch

About: I pretty much have the best skills ever...heck yeah!

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.)

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Get to Phones

Things you will need:

2 phones

( We have only tried it with a Razr and a Sync )

Step 2: Call

Now call the other phone, and pick up.
This shouldn't be to hard, unless your like my brother. =)

Step 3: Call Again

Now call that same person again with the same phone, do not hang up the first call, and pick it up also. So now you should have 2 calls on the line.

Step 4: Link the Calls

Now the real hard part,(not really.) Link the calls from both phones so that you are in a conference call. Your done, simple enough.

Now for the fun, but loud part. Put it on speaker phone(if you have it. It doesn't make a big difference, it is just louder.) Make all the noises you want. It is fun to make high pitch noises, it sounds like a Ring Wraith. Have fun!

This is my first instructable, so tell me what ya think.

    It's a simple case of feedback - right up there with annoying sounds you hear when someone is doing a speech and the microphone is too close to the speakers.

    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.

    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.

    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.

    Some people arent smart enough to know that. To these certian people anything unusual in life is a "glitch". lol

    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.

    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.
