Headphone output into mic input?

I've got a cheap voice changer that is hard-wired to a computer-style microphone. I cut off the mic and added a 1/8" miniplug adapter, so as to increase flexibility. I need to connect the powered headphone output of an mp3 player to this voice-changer, what is the easiest way to do so? I tried an attenuator I had lying around, but got no results (are attenuators one way?) is there a good (cheap) solution to this problem?

portable phone speaker/mic

Ok, so I have a portable phone and would like to create some sort of hands-free speaker/mic for it. I'm not sure how to go about doing it and I'm not very internal-electronic-savvy (i.e. chipsets, soldering etc). Ideally, I would assume it should be connectible via the 2.5mm headphone jack. I have an old 2.5mm headset. It's got an ear bud and flexible arm microphone and connects via 2.5mm jack. I should also have some old computer speakers lying around somewhere. I assume that's all I should need. I would like the microphone to be part of the device and be functional, but not sure if it will pick up my voice from a far distance. I'm not too concerned about looks/style, but would be a nice addition. Functionality is my first concern right now, although I do have a few old Fossil watch containers that I could put the speaker(s) in and some sort of dock or rest for the portable phone would be nice as well. If soldering is involved, I will need very detailed instructions. Thanks again! I hope someone can help me. If someone knows of a fairly inexpensive product, I would be willing to buy (since I'm not very soldering-savvy as I said above), but I think this would be an interesting project to build.

Wiring a 2 way radio headset to also record audio?

I am a hang glider pilot and like to take videos during flights. I would like to add narration and the back and forth communication with my chase driver as part of that. I have a headset in my helmet that is wired to a ham radio for that communication. The jack to the helmet is a three conductor, 1/8" jack that goes to the earphones, microphone and a common ground. There is a push to talk switch that trips the radio to transmit which is between the helmet and the radio. What I would like to be able to do is put a jack/splitter inline with the existing jack to then go into the mic jack on a voice recorder to get three things; Radio audio (receive), Radio audio (transmit) and me just talking into the headset mic - Narration.Not sure how well I am explaining this and I could just experiment, but I am thinking it's not as simple as just wiring stuff together. I'm good with a soldering iron, but no EE by a long stretch. Any thoughts? Thanks

Is it a good idea to wire an ELECTRET mic in parallel? What are the advantages and disadvantages? Answered

I already made a prototype of a low-noise desktop microphone (with an internal 5 stage transistor preamp). It only had one ECM capsule inside. A few days later I found a couple of pictures of a certain microphone with two ECM capsules wired up in parallel. It made me wonder, will it increase the sensitivity of the mic while reducing noise or will do the exact opposite? Is is a bad idea to hook six of these in parallel? Sorry, I'm not an expert when it comes to microphones. Before I post a guide, I wanted to make sure of what I'm saying.  The Reason: If you are familiar with the Blue Snowball USB microphone, you'll be surprised on what's in it. I recently discovered that it has two "Electret Condenser Mic Capsules" soldered in parallel. I thought there was something special about the Snowball since the reviews went crazy (4 1/2 stars on amazon)! I was expecting a huge diaphragm, but no, it only had two tiny ECM mics soldered on a Preamp + USB DAC. Lesson learned! Never underestimate an ECM mic.  ______________________ The picture is my prototype, it's working great right now. Luckily, the 5 stage preamp is giving zero noise. I'm planning to add a USB D.A.C. and an ECM array on my final version.

A preferred source for buying microphone elements?

On top of that, the transformer inside the mic was wired in a very odd manner and someone has clearly tampered with it, so who knows what has been done to it. I am considering buying a new dynamic mic element and replacing the old one with it entirely. Can anyone recommend a preferred source for buying decent mic elements without having to but a whole microphone? At that, anyone know where to buy vintage mic elements?

Phase Cancellation to Prevent Feedback

The Grateful Dead's wall of sound prevented feed back by having two mics for each vocalist with one of the mics 180° out of phase of the other. Then mixing both mics on the same channel. So the only information that wasn't canceled was the voice.  This gave me an idea. I took a handset and added a mic facing backward from the existing mic. Then wired the second mic out of phase. Apparently there's more to it electrically then just wiring the other mic backwards because the handset went dead. Is this possible with just parts salvaged from old phone equipment?

I really want to make a servo rotate like when using the sweep code but with a microphone instead of a potentiometer. the servo would move depending on the decibel level and return to it's default position once the noise stops. i can code myself but i don't know where to start and i can't understand the microphone related code parts, i could really use some help with getting started, i would be greatful on many levels. EDIT: i scraped this together but it doesn't work exactly how i want it to #include int micPin = 1;    // select the input pin for the mic input       // select the pin for the LED int micValue = 1;  // variable to store the value coming from the mic Servo servo09; void setup()   {                        servo09.attach(9);    } void loop()                     {     micValue = analogRead(micPin); // use what ever threshold between 0-1023 you wish to switch  the led         if (micValue > 2)     {                         servo09.write(10);         delay(1);     }     else     {                         servo09.write(100);         delay(1);     } }

building a HD Audio front panel for my PC. Audio circuit?

Hi! I have problem with my computer. the motherboard has HD-Audio but the front panel is the usual AC97 standard. You can change the BIOS config so the front panel audio connector acts as an AC97 one, but then the problem is the speakers connected to the back keep playing even if you connect a set of headphones to the front panel. The reason is the audio jacks used for HD-audio are different from regular jack connectors (and very rare to find!). While the insertion of the plug in a regular jack connector results in breaking a circuit (and so, physically muting the loudspeakers), in an HD Audio jack, the insertion of the plug results in closing a switch (sending a signal to the driver ordering to mute the speakers by software). I managed to create a sort of HD audio Jack by combining a regular jack connector and a zero pressure micro-switch so when the plug enters the hole, a tip inside the hole closes the micro-switch. I wanted to make a good quality front panel so instead of just wiring the jack connectors (and micro-switches) to the cable, I decided to add an EMI filter. I took the circuit from this doc: http://www.formfactors.org/developer/specs/A2928604-005.pdf and more precisely from fig 6 at page 25. The circuit uses two 220 pF capacitors and two inductors for each jack connector. In this aspect the circuit is identical to that proposed for AC97. The problem is I have no idea what inductors to use or how to ask for them at the shop. All the diagram says in a footnote is: ZL should be 600 Ohms or greater @ 100MHz with a low Q (broad Impedance curve over frequency) but not even the guys at the shop knew what piece to give me. So what I did was to cannibalize the inductors from two cheap promotional radio receivers with jack connectors for the headphones and use them for my circuit. After all, they perform the same function: filter the audio signal at the headphone connector so I supposed they should have the correct values I needed. But my circuit is very noisy! headphones have a constant electronic background noise (that seems to react to things like mouse movements, hard disk activity or whiteness of the screen) and microphone has a lot of noise (of course I'm using very good quality mic+headphone). The cables are audio cables for front panel audio so they are supposed to be correctly shielded so the problem is in the circuit at my custom board. I would like to make a tutorial (including HD Audio connector construction) once the front panel is working properly but I don't know how to fix it. Any ideas?
