Hi there, I'd like to change jack of some headphones I have. Original jack has 3 pins (left, right, power) and a switch on/off for power, now I want to use a standard 35 mm jack... How? I have 5 cables: blue, red, green, gray, brown... I'm sure blue and red go to same pin but no idea which of others go together... Any suggestion please? Thank you

I'm looking for the tiniest power jack socket possible for charging an internal battery. I'm considering micro USB, but it's difficult to solder (and it would be nice if the plug didn't have an up and down direction). Can anybody suggest alternatives? Thanks.

I have a pair of airline headphones that have a standard 3.5mm jack for the audio but require power to an additional 2.5mm jack in order to work. I'm looking to use them with a desktop PC so thought about getting the power supply from the USB but am a little confused about how I can get it there, I've had a look around on ebay to see if there was someone that was selling a 2.5mm female to USB jack but havent managed to find what I need. Do these things even exist? Or would I need to get myself a 2.5mm female connection and wire it up to a USB lead myself?

Question by giantjamsandwich | last reply
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?

Can I have a silly technical question for which I would have known the answer if I only paid more attention at school? how is possible that stereo headphones, ie 2 speaker circuits use only 3 cables? I understand the "ground" is the one that both speakers,ie left and right have in common but how come it doesnt bother the signals which go to the speakers? doesnt the left signal get mixed up with the right signal? and why is it called "ground" when it's not actually connected to the ground, like for example lightning conductor is? I've read through the wikipedia article about TRS several times but still can't understand it. thanks for answer, I promis I won't forget it this time :)

Power jack on Dell Inspiron laptop is broken. Rather than fix it, can't I splice something onto my power cord that will plug directly in through the battery panel's access? Sure, you'd have to stay plugged in without battery, but it's a temporary fix that doesn't involve taking the thing apart...
The plan was to add a stereo output jack and a switch to turn the speakers on/off. This way I could leave a cord plugged in and still have the option of switching the unit's speakers on or off. Anyway, a visual inspection of the circuit board shows that the two grounds are isolated from each other. The plan was to tie the grounds together and switch with an spdt between speakers and the jack, then add another set of positive leads to the jack for left and right. Now that I see they are on isolated and separate circuits, I am hesitant to tie them together. Maybe I just need to go with RCA jacks and a dpdt? I guess my real question is "am I going to blow up my radio?" Do I need to worry about dummy loads or about frying the driver circuit? I realize the audio level will not be "line-out" and I have read that a 1k resister will help, but I don't mind turning down the volume before running the signal to another amp. Thanks!?

The idea is to install pneumatic jack on each tire. to lift the car when a flat tire occurs. one side at time, the system need to include security system to avoid unintentional or accidental operation when the car is moving. also the system could be hydraulic operated by 12 volts pump
I've been searching out parts on digikey, and noticed that a lot of the power/audio jacks had an "internal switch", with three conductors and four contacts. I've never heard of these before, and none of the datasheets were helpful, nor ten minutes of googling, in educating me. So what are these mysterious internal switches? I presume they somehow switch between two states depending on if there's a plug in the jack. But why is this helpful or necessary? And more importantly, how does this affect how to wire the jack?
Question by Skidion | last reply
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?

So hey there instructablers! I had a laptop with a loose power jack and a bad battery that was working perfect but when i moved the charger a little bit it was losing contact so it was turning off. One day i decided to rip apart the laptop and see if i could fix it. I opened it only to find that the jack had completely come out of the board! So i came up with the idea to solder the charger wires directly to the board without a jack. It seems possible, right? But i got into a problem! I couldn't find which of the remain lead was the positive and negative. I have attached a photo and i have circled the jack lead and number them. If anybody could help me buy explaining me which lead does what i would appreciate it! Thanks in advance!

Question by s117 | last reply
I have an old dinosaur laptop (a Fujitsu Life-book C2330 approx. 7 years old.) that worked up until very recently. I packed it up in my closet for a few weeks, and when I decided to re-purpose it, the laptop wouldn't power up. I believe the problem is not in the laptop itself, but in its power transformer. When the transformer was working, it would make a high-pitch, low volume, whine. But now the transformer only whines once for a half second every five seconds. This could maybe be attributed to a blown capacitor or other electronic mishap. If that is the case however, it would probably be more worth my time buying a new transformer. My second idea is that the transformer has been damaged but usable for a while, but the laptop requires a slight charge of some kind in the battery to get it going, and the old transformer doesn't have the guts to give that charge. Metaphorically leaving me with a car with a dead battery, trying to jump-start off another car with another dead battery. If this is the case, then I should buy a new battery. My third idea is that both the transformer and the battery are not the problem, and it is the power jack that is the problem. I had to open the computer up not too long ago to re-solder the loose power jack. The screws that attached a ridiculously large EMI cage to the motherboard were stripped, so I had to drill them out, and then bend the EMI cage about 45 degrees. That allowed me to fix the power cord, but it also damaged my internal wireless card. After putting it all back in one piece, the laptop worked fine until I bought a new one, when I put it in my closet and forgot about it. Which brings me back to the thought that the power jack is broken. But it doesn't look broken at all, it doesn't feel broken, and it doesn't jiggle in the laptop. And if the jack is broken, I might as well just give up. The last possibility, is that the laptop, the transformer, the battery, and the power jack are all usable, but the power cord, which looks fine on the outside, might have lost its conductivity, or become frayed and detached inside its rubber casing. Which can be easily fixed by opening it up and reattaching the wires. That's my situation. I don't know which of these ideas it is, but it has to be one of them. I appreciate any help I can get. Sorry for the bad image quality. Not that the pictures help much anyway. Thanks, Sam

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?

Greetings, my laptop DC jack stopped working properly a few months ago and today when i woke up the charger pin was so hot that it had melted the rubber end, so finally got a spare DC jack and cable to replace it, since its not soldered to the motherboard, but the only one i could get is a simple DC to motherboard, meaning 2 red and 2 black cables, like the one in the picture above and this laptop uses one similar to the other but instead of 1 extra black cable uses 3. So anyway my question is, are those extra black cables regular grounds? They're screwed to the motherboard on different places. Can I somehow just splice those 3 to the 2 that the spare cable i got has? Thanks!

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 recieved a free, working TV the other day. The only problem with it was the pin from an RCA video cable had broken off inside the socket. I didn't want to spend money on an RF modulator for my DVD Player, so I figured out a pretty solid way of getting the pin out. 1.) Find a needle 2.) On a hard surface, bend the very tip of the needle slightly so that it forms a tiny barb. 3.) heat the tip of the needle with a lighter until it glows red hot. 4.) stick the needle into the plastic core of the broken RCA pin 5.) wait a few seconds for it to cool 6.) pull the needle out, and the broken tip should follow!

Hello everyone, I am struggling on the proper way connect a few parts in my power source. At the moment I am about to wire my rheostat to a mono jack. From there I need to wire a 1uf capacitor to a 2nd mono jack. I do not understand where to connect each wire. I know how to wire the rheostat to the first jack but from there I do not know how to properly bridge the 2 jacks with the capacitor. I know I need to connect both jacks but how do I wire this? Do I connect the capacitor between both "ground" leads on the jacks? Does this also constitute connecting both jacks in general? Also, the 2nd jack will be connected to the rest of the negative circuit in the source. I really hope I explained this well enough. I am new to electronics and I am still not that familiar with terminology so please bare with me. I would appreciate any help offered. Thank you in advance!
