Making an audio transducer with easy to obtain elements?

I have any old longplays, and I wish converts them to MP3. I have too an old turntable, but it lacks the pick-up. I think that perhaps from a pair of headphones, a transducer can be manufactured. Someone can give me some suggestion?

want to add built-in bluetooth audio receiver to an active Speaker

I like to add a bluetooth audio receiver to a Sonos Active speaker. I would like to build it inside the speaker so it looks nice too. I assume I have to get one of the Bluetooth Audio receiver boards like this http://www.dx.com/p/xs3868-bluetooth-v2-0-stereo-audio-module-green-385930#.VVPymNNViuc . I think I should be able to find a 5volt connection somewhere in the Sonos speaker to power this unit and then have to hook it up to the AUX connection in parallel to get the audio going.  I was wondering if someone knows of a good bluetooth audio adapter that can pair multiple devices.  Also any other ideas or suggestions would be appreciated.  Thanks

Single Audio Input to dual input

Hi, I have an amplifier that only has one input, but I was hoping to have a bluetooth connection, as well as a 3.5mm audio jack. I was wondering if there was a way that I could do this? and that preferably it would switch automatically based on which is being used?

Custom audio mixer box

I need a device to do the following. One input source for stereo (ipod), one input source for mic. Two stereo outputs to headphones (ipod earbuds). The device would mix the input audio (with a volume control for the mic input) before sending it to both outputs. Is this something that can be bought? If not, anyone interested in making one?

Car Audio Kludge

I recently bought a used car. It has a radio, but no faceplate. While I could probably find a replacement faceplate or even install a new radio myself. I want to see if I might be able to DIY my own stereo out of the bits of my radio I do have and maybe an MP3 player or something. I figure the amplifier and power systems are all hanging out in the box there. So all thats actually missing is the part that acutally makes the audio to send to the amp. Anyone out there know enough about car stereo to confirm/deny my thoughts on this and maybe provide some advice?

Any ideas if this would work (i'm a total noob on this) red=negative blue=bass boost black= ground any suggestions on how to: make it work? make it sound better? louder without distorting?  make it more suitable for mp3player/ipod? how to add (and where to put) high and/or low pass filter? the 10k log pot should serve as volume control (hope that's correct XD) my jack's all wrong i need 1/8 stereo jack....so how do i put that ? how many watts for the speaker?     is a 9 volt enough to power this ?  would the switch on the bass boost work?

7.1 DIY audio switch, please help

Dear Instructables community,I stumbled on to this site while looking for a DIY solution to a problem where no commercial alternative seems available. The problem? I need a dual input/output switch for my 7.1 audio system.What I found on this site was: https://www.instructables.com/id/35mm_51_Surround_Sound_Switch_Splitter_Box/I'm "OK" with a soldering iron, but I've never really built anything before, and I'm not familiar with some of the terminology. Really, the only things I have done in the past have been soldering plugs on the ends of wires and re-soldering loose connections. Even so, I'd like to build something similar but for 7.1 with dual inputs and outputs.I'm hoping you can help me make the right choices building this.My original plan was going to be just like the 5.1 version with a few most switches, but instead of the input 3.5mm jack as the source for the switch, I would just connect another switch and then connect it to two 3.5mm jacks.(See attached image)Will this work without taking a hit in audio quality?Is there an easier or more efficient way of doing this?Here's the hardware I selected initially:Switches: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId;=10001&catalogId;=10001&productId;=76260&3.5mm jacks: http://www.allelectronics.com/make-a-store/item/SMJ/3.5MM-STEREO-PHONE-JACK-W/N.O.-SWITCH/1.htmlI don't understand most of the terminology on these parts, but they look like they should work.Please let me know what you think, I'm open to advice.Thanks!

Potentiometer help

Hello,I'm new here and pretty new to home audio/electronics projects so please bear with me here.I created my first clock amp a while ago using a Minty Amp kit, an Ikea alarm clock and some other bits and bobs. Here are some images:frontbackgutsI failed to take progress pics so couldn't create an instructable for the project but I plan to do that with my next one (I've had a lot of interest with people actually asking to have them made to order - which Mr Minty Amps, Bob Hickman, assures me is cool). Anyway, so I've ordered the parts to make another clock amp but decided to get some extra bits from Maplin.co.uk this time. In teh first amp I used a 250k guitar potentiometer for the volume but it's not sensitive enough and really only has three settings (full, quiet and silent). So, this time I ordered this 1k pot from Maplin. When the pot arrived it has a 50mm shaft which is too long for my project. I assume I can just trim the shaft down so long as I'm careful since it's only plastic. Is that right?Also, because it's not a guitar pot, the shaft is smooth and so the standard control knobs I have will not fit it. Does anyone know of a (cheap) type of control knob that will fit such a pot? I really don't want to have to glue a knob on there.Thanks for your help.

Bluetooth adapter for car audio

Dear all, I have a Skoda audio system integrated into my Skoda which has a cd reader plus a cd changer, but  only a CD button(no AUX available). I would like to stick inside the audio system a Bluetooth receiver so I can listen to music stored in my phone. The goal is to solder a Bluetooth receiver to the audio system without loosing the cd functionality. On top of that I would like to be able to change from one source to the other without having to use an external button like a 3PDT switch. Thanks in advance, Pedro

Video and audio ads

We typically only allow ads to contain audio if the audio is user-initiated. Within the last hour, I noticed ads from Woolite, AirWick, and Lime Away with audio that started as soon as the ad loaded. I apologize for these, they should not be on the site. They are coming through one of our indirect ad networks, and I think I have stopped them (though it might take half an hour from now until the change takes effect). However, if you see any more, please let me know. If you ever see ads that don't fit with our values, make a note of the URL they link to, and where they are coming from by looking for an "Ads by Google" or by looking at this Instructable to see which network is serving them:https://www.instructables.com/id/Instructables_Ad_Networks/

Motion sensor audio device

Hi. I wanted to make a device that would play a piece of audio that I recorded when I trigger some sort of motion sensor. I don't know what parts I would actually need as far as a motion sensor, a record/playback device, or other misc parts. I have a fair understanding of resistors and voltage but I'm pretty much a beginner. If anyone could point me in the right direction, that would be well appreciated.

Raspberry Pi sensing audio?

Hi all -- I have been programming all kinds of things all my life, but I have never had a chance to build a program that responds to audio input.  Suddenly: Dancing Baby Groot.  I have a great idea for an algorithm for making a very clever and funky Dancing Baby Groot using Raspberry Pi or Arduino -- if I can figure out how to get the processor to "listen" to audio input. How would I get one of those processors (or any processor) to "listen" to the mic and translate it into either digital or analog data which one could then plunder to figure out the tempo and beat in order to get Baby Groot to Dance?  I am 100% sure I can do the plundering (because it works on digital files) if I can get the processor to "listen" to the mic and create a file of numbers which represent the music being played. Any suggestions?

Bluetooth TV audio for Disabled Vet

I am a disabled vet having suffered hearing loss in Iraq (amongst other things). I wear hearing aids and was given a device by the VA that I wear around my neck.  It is a bluetooth device that pairs my iPhone to my hearing aids.  A different device I was given plugged into my TV and sent an audio signal to a set of headphones.  The idea is so that I could turn up my volume w/out affecting everyone elses. BUT... I never got it to work, AND it's been lost since I moved. SO, I was hoping the community could help me figure out a way to incorporate the bluetooth idea but instead of from my phone to my hearing aids, I'd like to go from my TV to my hearing aids.

Listening with Stethoscopes through Glass Windows?

I'm writing a zombie apocalypse fiction story and in one scene, one of the militia has to eavesdrop on a survivor gathering through a padded window using a stethoscope modified to fit onto a walkie-talkie earpiece microphone (the type that's along the same wire as the earpiece). The stethoscope would be placed against the glass window. The eavesdropped survivor leader is using a loud announcement voice with no acoustic assistance, in the middle of, say, a 20m x 10m x 3m lobby. The sound would (theoretically) reverberate through the glass window and into the stethoscope, which would focus all that sound down into the mic, which is transmitted by the connected walkie-talkie to our actual listener that hears it several kilometers away through the second, receiving radio. Notwithstanding the padded window (since the character finds a hole) and assuming the transmitted signal isn't distorted at all, how bad would the audio fidelity be for the listener? Would you still be able to understand audible speech? Would listening with stethoscopes through glass windows even work?

How to solder newer thick cables and new 3.55 jack for Vintage headphone Mod?

I purchased a set of crystal radio headphones on ebay which I wish to remod into working headphones. Instead of using the same cableing that is already on a set of regular headphones I wish to install in the old ones, I wish to solder new, thicker wireing onto the crystal radio cups and solder a new 3.55 mm gold jack onto the ends. To help you understand there are 2 good tutorials online , but they dont explain what type of new wire to get or how to solder a new jack on. I am not 100% sure what type of audio wire to purchase. All the wire I see at the electronics store is the red or black kind, with the one solid copper wire or the regular gold speaker wire.. but headphone wire is different because it has multiple colored strands that I need to twist into 3 for Left/Right/Ground https://www.instructables.com/id/vintage-wartime-radio-headphones/ and http://steampunkworkshop.com/g-headphones.shtml I like the look of re-wireing new cable to the outside of the cups, instead of just running the same cable straight through the cups. New, thicker wire will stand up better and the new jack would last longer as well. I was thinking wire between size 18-22 maybe?

Help with Arduino sound/spray

Hey guys, I need some help. I'm working on making a horse costume for an event. The horse will be out interacting with public. I want to have speakers in the cheeks that play pre-programmed sounds and I also want it to be able to "sneeeze" I've never worked with arduino before, but I really would like to try and I would like some help or some ideas. The way I'm hoping to have this done is to have the sounds activated by buttons that are close to my fingers so i can just move a finger to get the them, and have the sounds play out the speakers in the cheeks. Also, what I want is when I push a certain button I would like the horse to make the huffing sound and spray water out of it's nose. (I'm going to have a fan in the nose for ventilation, and I'd like it to just spray through the van so that it mists a person) Can someone help with with ideas of: 1) how I  can program the separate sounds 2) How to program each sound to a different button and 3) How to program is so that when I push one of the buttons it will simultaneously mist and make the sound. Please remember I'm new to Arduino, so as "dumbed down" as possible would be great. If there's any 'tables up that I may have missed that could help me with this, it would be much appreciated if you could link them to me. Many thanks!

GREAT ELECTRONIC AUDIO ITEM JUST CAME AVAILABLE

The Electronic Goldmine  has a rare to find component. "Tiny audio optocoupler is about the size of a pencil eraser and has 4 leads. These are used extensively in audio compressors, audio level controls, audio limiters, expanders/noise gates, guitar tremolo effects, guitar amplifiers and music effect boxes. Inside the black epoxy case is a 2 lead photocell (not a photodiode or photo-transistor) and a 2 lead LED. This is why the device finds extensive use in audio applications (photocell instead of photodiode). The LED requires about 10-16mA current and the resistance of the photocell varies from 150K up to megohms when the LED is off to under 400ohms when the LED is on." A
