I want to build a tube headphone amp. Is it possible to make a smps (switch mode power suply) to power it? It would be like a mix between old and new technology!

This goes with my last post on putting an Ipod in an old CD player case. I now have an idea to have a switch to change the sound output between headphones and powerd speakers. Again I tried to research how to wire a switch and this is what i came up with.

Does anyone know how to make an item that will let you plug in multiple 1/8" sources (radio, ipod, phone...) that auto switches to a single output by sequence, so the ipod is playing but when a call comes in the audio from the phone makes the switch bypass the ipod till the call is done then goes back to the music? i would love to get some help with this thanks Jake

I am trying to take an old "portable" speakers (which is rather large), remove the speakers, solder on heaphones, and make a new more portable version. I did all that. But the sound coming from the speaker is so soft I can hardly hear it and it is choppy. Before I removed the speakers, it worked very well and loud. How can I make it louder?

Can anybody tell me how to make a wireless headphone and microphone. Both microphone and headphones should be wireless. I found that one can buy a wireless headphone or a wireless microphone, but not a combination of both. Why I need it. I make long phone calls, during which I need to walk around. 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. Therefore I need one wireless headphone with mic.

Hi. I purchased some decent headphones a little while ago and my little brother was playing with the cats with the jack. One of them stuck their claw through it and it needs replacing. They were pretty expensive headphones, so I want to repair these. Will any old solder do? I like my sound quality. I've only got Lead-free crap ATM. Cheers, Josho.

Every lose ear buds (the soft part on them), everyone has now you can get free ones from Acoustic Forge http://acousticforge.com/, you just pay S/H and you get free earbuds, if you want to support the Acoustic Forge product : IronBuds, which are fully-hackable headphones you can make a pledge at kickstarter (link on webpage). For donating they will send you a pair (or more) of headphones and you will be supporting new, modular, headphones, each part of the headphones is separate, so you can customize the bud, headphone, cables, and much more! If you lose or break a piece rather than buying an entire new set you just have to get a single part of the headphones!

I have a stereo bluetooth headset which has a right channel earbud connected to the mic part and a detachable left channel earbud. I opened it up and found a green and copper colored coated wire going to the right earbud then another set of green and coppor coloerd wires going to the plug in for the left earbud. Using a left/right audio testing program on my phone I tried wiring the wires up to a set of headphones to test which wire is which. When I wire up the green right wire to the right channel and the copper colored wire to the ground I get sound through just the right channel as I would expect. When I add the green wire from the left channel to te left connection on the headphones both channels play through both sides of my headphones. When I did those tests I was assuming the copper colored wire was a ground. I then reversed the colors assuming the green wire was the ground and repeated the same test with the same results. No matter what combination I connect the wires in I cannot isolate the left channel to the left side and the right channel to the right side. Anyone have any ideas?

Hi, I own an Alcatroz Airwave 300 for 6 months and I have issues with battery. I always use it when I got home from school, doing homeworks, doing household chores, even going out to the public. I always charged it until its full but they only last for 2 1/2 hours. Recently, I noticed that my battery discharges easily. It doesn't last for 5 mins. So I decided to open the headphone where the battery and bluetooth module was installed, then the battery inflated and exploded. I was lucky that i'm not hurt but then I had no money to replace those. The warranty on this thing voided so I got no choice but to replace it. One day, I was looking for a potential replace for my headphones then I found my old nokia. It's display was damaged but the battery is still good. After 6 years of owning it, I can't believe that my Nokia battery still runs good as new. I thought to myself "why not". Also there is another problem, I don't even know how to solder a simple wire. I have the basic equipment so I need your thoughts and advice including how to do it.Note: before the battery exploded. I lost my receipt after I puchased it, without it, then I have no free warranty. Plus these thing were the last of its batch ever sold as a bluetooth portable headphone.

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.

Hello all, can anyone help? I am currently repairing a number of electronic keyboards, most of which have faulty headphone sockets due to plugs being inserted and then taken out sgain. I want to create a headphone box which splits the output but also enables you to switch the headphones of without taking out the plug thus minimising wear and tear on the socket. Any ideas please??

I am trying to attach a apple headphone jack to 2 speakers. Which wires do I have to put where because on the right side there are 3 wires which are the red, copper, and the red and green wire twisted together and on the left side there is the green and the copper and is there anyway that you can control the volume on your ipod from the remote that's on the headphones??

I use my laptop to play music...(using virtual dj software)....splitting the jack .. the volume from headphone is ok when playing small system.... big system the headphone volume is low....i need more ..i buy a volume switch (B5k) thinking that will solve the problem ..but when i connect it and turn it up its the same volume i get as if i just connect it without... QUESTION can i add any thing to this to make the headphone louder..without using any external power source 6v,12v battery etc

Hey guys, I'm putting a spare three month pro subscription up for grabs, because I collected three in as many days. So to win the three month subscription you'll need to come up with an awesome project based around headphones, it has to have been published after this topic and mustn't be a rehash of the same project you did a month before... Feel free to take the theme loosely though it's just got to involve headphones. As soon as you've published your instructable comment with a link to it. Contest ends on the 30th of june, when I'll be lying in the sun with my girlfriend making her help me choose the winner. RANDOM PRIZE - If I can afford to give another membership away there will also be a random prize given out at the end of the contest. Patches for all participants in the contest, out of my personal stack, so hopefully I don't run out. ***UPDATE*** It was a tough thing to decide, I loved the quirkiness of have knit headphones, think the idea of having freedom with headphone choice and bluetooth was cool, the versatility of having a volume control for everything but overall my love of blinking lights won and I chose the Led music synched headphones, mainly because the idea was cool and because I like the thought of making this with a big pair of headphones to make glowing domes on my head. Congratulations plugable I hope to run more contests like this, only having four entries was a bit disappointing but I suppose it's tricky getting started... With any luck I'll eventually have really awesome contests...

Hi. I want a box where I can select whether I was the signal to go to either my headphones or my desktop speakers. I know I can just get a 3.5mm splitter cable, but I'd prefer to be able to switch of either one when it's not being used. To get around having to use several switches, I thought of this. If you think (like me) that it'll work, could you please let me know. Thanks, wbr

I have some vintage Superex Stereophones, model Pro B-VI (with a google search only find an ad in a paper dated 1973 referencing them). They have both a tweeter and a woofer in each ear, and I believe the resistors in the crossovers have gone bad. The high end drops out now and then to pop back in after a short while or after a minor volume adjustment - other than that the volume is crystal clear. Am I right in assuming the resistors could be the issue? The other components in the crossovers are just inductor coils, which are know are for the low pass, so it can't be those. I know instructables isn't a electronics repair forum, but I wasn't too sure of where else I could ask and find knowledgeable people. I love this site. :) I.W.

How are headphones/earbuds powered? Is power sent through the audio port? If so, how many volts go through? This question how always wondered me. Because earbuds are basically mini speakers and speakers require power, so shouldn't headphones need at least a little power?

Hello, so I have a Orange amp, the crush 20 rt model and it plays just fine. When i want to play the sound to the headbphones it doesn't play. There is amp amp plug and the headphones plug, next to the headphones is the aux where i plug my headphones, but when i play, the sound doesn't go to the headphones. Any solutions? Also sorry if there are any mistakes in my engrish.

About five minutes ago one of my friends brother told me my friend was annoying him by playing his electric guitar at 7:30PM as loud as he can so it got me to thinking, to make headphones that work on a guitar it couldn't be as simple a swapping the jack right? if i made the cassete player amp instructable and just plugged normal headphones into that, the headphones would work so only the guitar player could hear it right? my music teacher told me that plugging headphones into an amp was a bad idea for some reason so im just using that to try and make headphones for an amp another way

I'm working on this project: https://www.instructables.com/id/Legend-of-Zelda-Treasure-chest-with-sound/ This is the stuff I'm using: 9V recorder module: http://www.radioshack.com/product/index.jsp?productId=2102855 SPDT switch: http://www.radioshack.com/product/index.jsp?productId=2049718 7-8 white LEDs: http://www.radioshack.com/product/index.jsp?productId=3060980 I'm adding onto this project a little. The goal is to have the LEDs turn on when the sound starts and turn off after 6-6.5 seconds (while the sound is still playing, just before the duh duh duh duh!). I know the 9v battery isn't going to be enough. Somehow I need to introduce more power to light the LEDs to full capacity, but not overload the recorder module after the lights power off. Does anyone know what part(s) I need to make the light off delay work? I also need to find a way to line up the LEDS evenly along an 8" (width) by 1-1/2" area. I was thinking soldering to two strips of metal for positive and negative (two pieces separated with silicone rubber). Will my strategy for lining up the LED's along the back work? Any suggestions? I would also like to replace the speaker with a female headphone jack so I can easily record the sound without background noise. This article (http://kipkay.com/wp-content/plugins/download-monitor/download.php?id=10) also uses the same audio recorder and suggests it's as simple as wiring the jack to the positive/negative wires stating you can use a microphone or plug it into your computer. Isn't a headphone jack on a computer powered, whereas headphones are not? I would think the recorder module is already supplying its own power for recording. Wouldn't the power from the headphone jack potentially overload the recorder circuit? So is it OK to wire a female headphone jack to the positive/negative wires on the recorder module without a resistor? Any insight you guys could provide would be appreciated! Thanks!

I have been making headphones and need some help. when wiring I soldered the red wire to the red wire, and the blue wire to the blue wire. It works fine but i wanted to add an LED, can I solder the led between two of the red wires? If I can't, can you tell me another simple way to wire one so it runs off the headphones? PLZ HELP!
Posted by NetReaper 10 years ago
Look at the picture below. The headphones on the left have 2 grounds while the jack that I want to replace it with only has one. Is it possible? Pretty noob question but yeah.

Im in need of help. My friend has a bass guitar but no amp. And instead of buying one he asked me to figure out a way to let him just plug in his headphones. After glancing around at all the instructables for portable guitar amps I hadnt seen one for just plugging in headphones. SO, I'm asking here in hopes of someone else knowing where an instructable is for this, because I can't find one.

Hello, I am trying to connect a 3.5mm jack to a speaker I salvaged from an old radio. The speaker has 2 wires: A + wire (marked yellow) A - wire (marked black) The problem is, the 3.5mm jack has 4 different wires: on one side, there is a copper one and a red one on the other, there is a copper one and a blue one. I got the speaker to work for a few seconds while plugged into my phone, but I cannot remember how it went.

Hi, I'm attempting to put together something that is conceptually simple -- making a splitter for the 3.5 mm 4 pole audio jack so that one end supports a mic and the other a pair of headphones. I'm doing this because I want to hook up a better quality mic than found in the store-bought iphone headsets. However, after putting it all together, I just can't get it to work with my ipod. I've followed these pinouts (where 1 is the tip and 4 is the base): 4-pole jack 1. Left Audio 2. Right Audio 3. Ground 4. Microphone 3-pole jack 1. Left Audio 2. Right Audio 3. Ground Ive verified that all the connections are good using a multimeter. But when it comes down to actually recording with my ipod, I can't get the line in to work. Has anyone does anything like this before? Any ideas what might be going wrong? Is is it possible that measurements on the 4 pole jack isn't standardized and that the one I have doesn't actually fit the ipod correctly? Perhaps I'm completely wrong about how to connect the wires. So just in case, this is what I did: Line-in: Pinout (P/O) 1 and P/O 2 ---> P/O 4 (on 4-pole) P/O 3 --> P/O 3 on 4-pole (on 4-pole) Line-out: P/O 1 --> P/O 1 (on 4-pole) P/O 2 --> P/O 2 (on 4-pole) P/O 3 --> P/O 3 (on 4-pole) So yep, that's it. Any help is much appreciated : )

So, I've Had a Pair of ATH-MSR7 Headphones for a few months now and I've wanted to know how to turn them from standard wiring to balanced wiring with 3.5mm jack endings (Got the Idea after reading how to do this with the ATH-M50X Model, https://www.instructables.com/id/Balanced-Headphones-for-About-130/) If Anyone can give me an answer or point me to a tutorial (Trust me, I've searched, can't find a tutorial) i'd be mighty grateful. Many thanks for a reply. Also this is for a portable DAC with two headphone Jacks like a Pono or an AK240. Thanks again.

So I basically dissected an IMac G3 and took out the speakers. I'm pretty much clueless when it comes to wiring so i was hoping that someone could help me take the head phone jack from actual headphones and attach it to the computer speaker. Any help or suggestions would be much appreciated. (I attached a picture of the computer speaker and the headphones)

I've got a challenge. Will anyone try to figure out how to make usb headphones? i was looking at the razrs and thought about it, you'd need a driver on the phone and i wont be able to figure that part out. I was searching this site and saw posts on making headphones and thought someone could do it here. I want it so i can listen to music on my phone and razrs dont have an in/out audio.

I'm trying to wire two VU meters to some headphones so that there is a meter for each channel(one for the right, and one for the left). How would I hook them up? Do I need any special circuitry so that they work correctly? Attached are the meters I have still attached to the board I've salvaged them with.

These headphones make you look like a cat and can be bought, but this looks like an easy product to make yourself and try your own variations. Or if you want something a little more tough you can try for some scary looking horns. It's up to you.Link via bbgadgets
