phone into a microphone

I was thinking about trying to turn an old phone into a microphone for a music performance or something? correct me if im wrong and i probably am but, a small crap microphone is a telephone would work would it? i was thinking if i left the whole phone in tact but made the cord come from the phone base into a microphone jack, how would i connect a microphone jack that has 5 legs to a 2 wire phone microphone? it couldnt be done could it? It would work if i just bought a crappy microphone and moved and fitted it into a telephone so it has all the circuit or what ever else is in one already in it I apologize if most of that doesn't make sence

microphone wiring?

Ok i was wondering if i took a microphone that was real cheap from walmart and take the male part off the end of it and put a female part so that way i can plug in a dual male sided cord to it and then to my computer, more or less im wondering, can it work like that? and then i was wondering if there is a program that when i plug the mic in that it works like plugging a guitar into an amp, as in it plays the input to the computer outloud without being in playback from a recording

microphone help?

I'm hoping that you Audio folks can help me out here. I'm trying to make my own microphone setup for gaming, however the only problem that I am having as of right now is that I cannot figure out how to connect the earbud with the microphone itself. If anybody has any ideas as to how to do this please let me know, I am also hoping that I can do this without an op amp as I have never used them before and am completely clueless when it comes to how they work, if somebody wants to let me know how they work and how to set one up then I'm all ears ( or eyes in this case ) I thank you in advance for your assistance.

Microphone wiring? Answered

I have a broken microphone. Its wire is cut  inside the insulation. i want to replace the entire cable. when i removed the plastic cover of the microphone i saw a red and a black wire soldered to it.  Therefore it uses only 2 wires but in the connector it is a TRS one not a TS one. i will also replace the connector.  i am wondering how should i wire a TRS connector which has 3 leads. one being the common ground. but the other 2.  should i short them out and connect the red wire or must I connect the wire to only one lead?  Then if i buy a $0.2 TS connector and i wire it accordingly. will it work? One another question does the microphone device has polarity that is should i connect  positive to positive and negative to negative lead. because there is no indication on the Mic?

If I use a cordless phone, I have to keep holding the receiver with one hand all the time. If I use a speakerphone, everybody around listens to the conversation.

FM Wireless Microphone receiver

About a year ago I got one end of an wireless microphone system at a yard sale. As far as I can tell, it is the sending unit. The recieving unit is lost to posterity, which is why it was so cheap, and has since been collecting dust. It has an RCA line in, 1/4 inch microphone in, a squelch knob, an output knob, a two-foot antenna, and a power button. It says it operates at 49.83MHz FM. I don't have a receiver that will pick up that frequency, and I'd like to know what it would take to build one. Perhaps mod an existing FM radio?

How do I convert an old pair of headphones into a microphone?

So I'm trying to convert a vintage pair of over-the-ear headphones into a microphone (using only one of the earpieces obviously) and I'm not sure how to re-wire it after I went and disconnected the 2nd earpiece. Basic info: The remaining earpiece has a tone knob, volume knob, and a mono/stereo toggle switch. It has a 1/4" cord compromised of positive, negative, and a ground. It's a 0.3W 8ohm speaker. I got the idea for this after seeing an old telephone converted into a microphone and I've been wanting to get a lo-fi sounding mic for a while now and figured I'd save some cash by recycling these old things.

Camera Suggestion

I do ALOT of youtube videos, but I also need still good quality still pictures and my camera just died. I have a budget of around $400.00 and need something that takes HD video I would like something that either has an external mic jack or takes good audio, my subscribers complain of a high pitched whistle in my current videos (I cannot hear it) It would also be nice if it could be set up to stream directly to a computer, as I would like to record classes, and some of them are 8-12 hours. If the Contour +2 took still pictures I would compromise on the picture aspect because I shoot a lot of outdoor action stuff, and a waterproof helmet cam would be nice.  Right now I use a Nikon S8000, and liked it, but it just wasn't durable (plus the sound issues) I know I am asking a lot, and will have to compromise something, but I cannot go over $400-$500 budget. Please recommend something you think would work

How do I make a Headphone/Microphone hub...

Hello, I'm a tabletop gamer and I have a problem. My problem is that sometimes I play at gaming rooms and there's usually a lot of noise there. What I was wondering is, is there an easy way of making a Headphone/Microphone hub that players at the table can plug in their headsets and thus ignore most of the ambient noise from the other people around them? I have an understanding of electronics and how to work with them. I just don't have the finer knowledge of how to actually make stuff from scratch unless I follow a blueprint with listed components to use. What's needed is something the "host" (be it a Gamemaster or the one who's running the game) can plug his microphone headset into and the players at the table as well (let's say 10 players, so that's 11 headphones and 11 microphones). And the host needs to have a means to talk to just some players at various times, and each player must in turn have the ability to speak to the host as well.  I'm certain this gadget or something similar is or has been made at some point in time, kinda like the conference tools corporations use for their meetings, just a little lower tech than that, and it needs to be easily transportable. I would be grateful for any help on this matter.

Wireless FM microphone real time voice/play transmitter

Hello I am looking to buy/build a small FM wireless transmitter with built in microphone (similar to karaoke but not exactly ) to transfer voice or sound  from playing  musical instrument  to earphone. It is meant only for practice purpose so does not need  high power, the distance between the microphone (the transmitter ) to earphone  is like from mouth to ear a few centimeters say about  50 cm. I am electronic junior engineer and have knowledge and experience in electronics mechanics and wave buy. Before trying to develop a new product  I was looking for a readymade shelf product. The first way I have searched the internet and reached manufacturer of Bluetooth solutions because of the plenty of Bluetooth earphone that are on the market, but quit a short time after I got some answers from the the Techs engineers  of the manufacturers that Bluetooth will not be my solution because It was not originally designed for true real time transmitting. The main problem is the latency time because there is a delay between the voice or play start until I hear it in the earphone there is improved in Bluetooth 4.1 and 4.2 that is 38 MS and may be not enough while fast playing, So as I was advised I started looking in the RF FM area. FM transmitters are long time in the market of stages and performers, there are high power grate quality transmitters that cost hundreds of dollars. Here is the summary of what I need :        I will need the smallest device (PCB) can be like FM spy bug transmitter. built in microphone (on the PCB ) , built in battery compartment (on the PCB ),built in antenna a copper loop on the PCB (no wire) Since there may be some problems like saturation of microphone or other problems with band width or  sound and sensitivity, sensitivity and control for the Microphone is important. Easy calibration of  tuning and stability , may be digital tuning is better. One option is to use the standard of radio FM 88-108 , but it possible that I can use FM VHF or UHF system that have both transmitter and receiver . If there are no ready made products thatn I can easy build a kit , or from schematic diagrams I will be thank full if you have any ideas. Nevat Ben Haim Recomp Computers
