Headphone-Speaker switch

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.

Switching the input to my speakers with a flick of a switch?

I have my 360 hooked up to my computer LCD as I don't have a regular HD TV and this is the next best thing. With my speaker system I normally have my speakers hooked into my PC sound card. What I think is getting a jack extender. Like it has a jack that plugs into my sound card and then I can plug a cord from my speakers into that so I could easily switch between my xbox and PC by just swapping cables. But I would like to make a little switch box so I can keep both of the plugged in and just hit a little switch and change them.

DIY Headphone/Speaker switcher

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

DIY Speakers

What we did was took different types of copper wire to find out which was the best for the quality of our speaker. We tried a wider gauged wire, a longer, and a couple other unsuccessful hypothesis´. The best one was the longer wire. About 1 meter long.  The things you need:  -copper wire -av cables -box without the lid -magnet from a speaker -av cables -stereo to connect to the av cable -tape to put you copper on the box

Amp for a homemade speaker box with car speakers?

The speakers are almost definitely going to be a pair Sony Xplod XS-R5743's Specs: 4-Ohm 190W Peak 35W RMS So with these power specs, what should the power ratings for the amp be? I considered building an amp, and unless there is something I've missed, it looks cheaper just to buy a car amp and just make it run from a wall outlet after a transformer. Especially when every amp that I see being built is a low power 1W LM386. Please, let me know the best method for amplifying the audio to these speakers and the required power. Thanks

Speaker on the blitz

I moved all my stereo equipment around a month ago or so. And I noticed that my speakers never sounded the same as before the move around. Today I got a little fed up with the shitty sound they had, and apon turning my balance on my mac to the left, the music sounds very tonal. It's not very bassy like my right speaker. If I turn it over to the right speaker it sounds normal, and shakes the room, but the left one does not vibrate my room worth 2 cents. I even switched the speakers around to see if it was my left channel on the amp, and it's not, it's the speaker. Anyone have any ideas why it sounds like this?? And yes, it was hooked up correctly, I did try switching the wires around, and it sounded worse, so yes it was connected correctly. These are technics twin woofer floor speakers, thought they were decent but my faith in them is very little right now. Thanks guys for anything you come up with.

Interesting Speaker Idea

Well, this is a totally random idea I had about how to see sound. I would like someone to try to build this if they have the resources available. Pretty much it is an airtight box with an woofer driver in it. On the top is an clear acrylic tube with a light ball in it. There is a rod across the bottom of the tube to keep the ball from falling out. The idea is when the driver moves back, the ball is pushed up in the tube, and when the driver moves forward, the ball is sucked down.

I've attached an example diagram i found of a DPDT switch, if i was to disconnect the lamp from pin 1 and the buzzer from pin 2 would the first position of the switch become Off and the second position become On powering the LED and speaker? also assuming that the LED and speaker only connected back to their respective batteries and not to each other, could i attach a low voltage battery to pin 3 for the LED and a higher voltage battery to pin 4 for the speaker without causing damage?

Anyway - what I got is a speaker with an electrical panel and an ON \ OFF button that turns the speaker on after ~ 3 seconds of pressing and holding the button. I do not have time to return or buy a new speaker so I wanted to know, if I added a simple ON \ OFF switch connecting the existing switch and the battery, I'll turn on the speaker and from that moment I will control it through the switch I added , will that give me the ability to control the speaker using the  switch I added?

Speaker switch box (2 x 2 or 4) with automatic ohm balance / adjustment, has anyone got a design for it please?

Hi, I have a cheap speaker switch box connected to my stereo amplifier as it only had one set of speaker outputs. When the smaller higher power demanding speakers are switched the box causes the more efficient floor standing units to shadow the sound which is annoying. The reverse does not happen, but when all 4 speakers are switched on the sound quality drops noticeably, as it would since the ohm matching is not right. I could buy an expensive Niles box but I don't exactly know the ohms for the smaller speakers since they have had the main drivers replaced (the original foam cone supports hardened and cracked in the dry heat of a few Australian summers). I suspect one set on, and one set off is a simple enough device even I as a novice could design it, yes i can, but would just building a better switch box using higher quality switches solve the shadow effect? and I have no idea about the 2 sets on so any ideas - a internet search didn't help much but maybe you call these things differently in the USA?

Portable Party box (A.K.A the toolbox speaker)

Hello all, recently I replaced all 11 speakers in my car since after 15 years or so they all had developed dryrot and stopped working. As many of you are aware however car speakers only come in pairs so I was left with one perfectly good (and expensive) speaker when all was said and done. So not wanting it to go to waste I devised a plan- I would use it to make a portable sound system. I went to amazon and purchased a dayton DTA-1, this little T amplifier runs on AA's and puts out 30 watts. Now all I needed was something awesome to contain this all in. Luckily during my  daily commute to school I stumbled across a rusty old craftsman toolbox left out at the curb to die; well needless to say its been given new life. Look at the pictures I provided to see whats what, but my basic plan is to mount the speaker in the lid by building a cradle for out out of plywood, cut to fit the inner contours of the box. I will then secure the board in place by using adhesives as neccisary. I also plan on painting the wood so it matches the toolkit. In the spirit of keeping things as utilitarian as possible I dont want to deck the thing out too much, but if you guys have any suggestions as to what else I should include in the build id be glad to hear them. (Leds, decoritive touches, ect.)

3.5mm 5.1 Surround Sound Switch/Splitter Box for 2 inputs

Hello, my first post here, so it might be in the wrong section, please move it if necessary. I have quite a complicated problem. Currently I have 1 PC with 5.1 speakers and recently bought a 5.1 headset with microphone. Already  I have a problem when I want to switch between speakers and headphones, each time I have to go under the desk and change the cables :/ In a few months I plan to buy another computer (old one is used up, but it is still quite good equipment). And here begins the stairs. I do not need a second monitor or keyboard plus a mouse, so I want to buy a KVM (keyboard / video/ mouse) switch. The mouse and keyboard are USB ones, so the KVM must support USB. Monitor and graphics card are connected through DVI, which I want to keep, so I must have a DVI KVM. I also want to be able to switch between headphones and speakers. So I thought about this: cs1782 But this works only for one 'source': I could use either speakers or headphones, switching from one PC. But I would like to be able to choose whether I want to use speakers or headphones on both of the PC, so I was thinking about doing (I have not found anything like this to buy, which is strange, because more and more people have the same problem) something like this. But as to be able to do: - Switch between headphones and speakers at PC1 - Switch between headphones and speakers at PC2 - Switch between PC1 and PC2 - Using headphones on PC1 and speakers on PC2 (or vice versa) simultaneously. I've came out with this picture, which should  be able to do this: - Switch between headphones and speakers at PC1 - Switch between headphones and speakers at PC2 - Switch between PC1 and PC2 But I still can't figure how to make this: - Using headphones on PC1 and speakers on PC2 (or vice versa) simultaneously. The more I  think about it, the more I get the idea that it can't be done via DPDT switches, but I don't know what to use. Is it even doable? I have no experience in electronics (I did solder couple of wires in my life, but nothing more), but I have a lot of enthusiasm, so I could make such magic boxes, if I knew how. Thanks in advance for any suggestions, ideas, etc. I also hope that this problem will be useful to someone else.

A Give-A-Damn box

I want to make a give-a-damn box. A small box with a 3 way switch that accomplishes absolutely nothing... the switch will simply display a green LED in one direction, red LED if flipped in the other direction, and breaks the circuit entirely if the switch is in the middle. The downside is I know virtually nothing about which resistors I need for which LEDs for which batteries I use. I'd like a single AA or AAA. I know overkill for powering a single LED, but I'm ok with that. The premise behind it is there is an inside joke that a handful of us at work have. Our give-a-damn is broken. So if they see this with the red LED, they know at that moment, I don't really give-a-damn.

Octopus in a box

On March 5th at the New England Aquarium octopus exhibit, a 7-foot long giant Pacific octopus climbed inside of a 15 inch-inch-wide box. The box was part of a set of acrylic puzzles that the aquarium uses to challenge the octopi during feeding time to keep them stimulated. Normally, the octopus opens the boxes sequentially to solve the puzzle and get its dinner. Last week however, the octopus found a crack in the largest box and rather than opening it, decided that it would crawl right inside.Aquarist Bill Murphy elaborates...What are the boxes made out of?The boxes are made of acrylic and were created by one of our long time volunteers in the fishes department.How many boxes are there?There are 3 different size boxes with different locks that are puzzles for the octopus to open.How do they work?I place one or two live crabs inside the box and the octopus has to learn how to open the box to get the food. I start the octopus off with the small box and once he has mastered the lock I switch to another box and once he has mastered each individual box I put a box inside a box to keep him active and challenged.What happened today?The largest box was actually broken by another octopus here at the aquarium three years ago so today the octopus decided to go through that broken opening instead of unlocking the large outside box to get to smaller box inside with the live crabs. This is the first time it has been witnessed here at the aquarium because they don't always open the box immediately and will wait till the night when they are more active to hunt for food. It's been a very fun occasion for visitors and staff!If octopi could live longer on land, we'd be their slaves for sure.Via New England Aquarium

I also don't know what I would have holding and playing the music. I would be fine if I had to shut the whole system down when I leave and turn it back on when I get back the next day.

Old JVC Boom Box (Antique?)

Hey guys, upon my travels the other day, I stumbled upon an electornics bin or two and one of them happened to have a few "ghetto blasters" or boom boxes as other people would call em. I should really get some better pictures, but these will have to do. I brought it home expecting it NOT to work at all, as usual. It DOES work but in a somewhat limited way. I brought it home upon the conclusion that it felt rather solidly build for such a small system and it looked the nicest out of all of them. The "Problems" sort of speak: * Well for one, the left channel doesn't work, but BOTH the speakers DO work. They both have battery compartments (6 C cells each speaker in series = 9v-ish?) and they both have "extension" cables so you can unhook the speakers and place them elsewhere, the wires are 4 strand ribbon cables and the power is also transported down these wires. I find it rather retarded, because at full length, these wires are a foot long at best?! I managed to get around this debacle for now and plugged the extension wire of the left speaker, into the plug for the right speaker, powering both speakers off one channel. This works half decent, but it doesn't go as loud as one speaker would go, and it gets distorted easier at high volumes. * The tape deck doesn't work. I hit the play button and it DOES indeed make a whirring sound, so my guess is that it needs a new rubber belt for the motor, and I have no idea where to get something that small. Did I mention that apparently the tape deck, actually comes OUT of the stereo, and theres a compartment for a set of AA batteries, thus turning it into a shiny silver 80's walkman. I'm ultimately dumfounded.. * The switches on the top of the unit, primarily the two buttons that change the "fuction" or input of the boom box, are crapping out really bad, like if I set it to radio, I have to raise one switch, and push one down, but it sometimes doesn't work, or it crackles really bad, or isn't as LOUD as it should be, but if I jiggle the switches enough, I can usually coax it into working. It's annoying at best. They are really impossible to get at and they're long pushbutton switches with a long plastic rod that pushes the switch on the board. I really doubt I can get these switches open and adjust/clean them. Should I maybe get the dremel out and but some little toggle switches? * It's missing the little faceplate for the radio selector? Oh well I can still manually tune in a radio station without knowing the number, primarily 94.5 the bull here, it's pretty hard not to miss it blaring some rock or heavy metal. I like this little unit and I wanna fix it up/tweak the crap out of it. If I could get subwoofers small enough, I would upgrade the speakers, reinforce the inside of the speaker casings with epoxy, and maybe dremel some bass ports (would that be a good idea? From what I can tell, it's a totally sealed unit, but it would probably benefit from some "bass ports"). Also, would it be beneficial to "reflow" the amp board? Like theres a board with a transformer and what appears to be a stereo transistor, but like a wide one for two channels, instead of two independant transistors for each channel. So I can only imagine if one side of the chip is working, the other side should too. Would it be a waste of time to reflow all the solder joints or no?

Headphones Speakers hack

I've been thinking about this for quite a while now. Since I can remember, I always had problems when it comes to these, after a while, I always end up with the same problem, my speakers not working properly, its always the same, one speaker works fine, the other not so much, same happens with headphones, one side just stops working, and I have to jiggle with the jack to make it work. Of course after I end up buying a new set of speakers/headphones and that's it. I figured this happens because I plug in and out the heapdhones too many times, I use the speakers during the day, but at night I can't be loud so I swith to heapdhones, well, at least, this is my guess about the problem.

Alrighti posted this before but it seemed like people didnt understand what was going on. Altight, we have a box and our first switch is a rolling switch (SWITCH 0) that is used to make sure that it only works if the box is closed. Then we have a series of 5 switches that are basic on off switches {SWITCH 2, 3, 4, 5, 6) and the switches are used for how many ignition we wish to do at one time but these switches have to be switched in order so example we cant turn on switch 3 without first flipping switch 2 and etc but these switches will light a light a soon as there flipped on still with the rule that the previous switch must be switched first also the switches run a positve current throu our first alligator clips of the ignition cords. then we have a main switch (SWITCH 7) that has a cover as a safety and this will also turn on a light and this switch will run current to our last switch (SWITCH 1) which is a momentary push switch that will run the negative current to the second alligator clips of the ignition cords thus setting off what was wished to be ignited. but we have the problem of the current bypassing (LOOK AT THE PICTURE) so therefore switch 7 isnt needeed bet yet it only is used to light up our (LIGHT 6) so we need to figure out how can we prevent this from happening without completely rendering our circut.

Help picking DC on/off switches

I'm in the process of trying to build a battery powered trailer mounted speaker system and i've got nearly all the parts now except for power switches. I didn't think i'd have a problem with choosing some but after searching around the vast majority of switches seem to be rated for AC or 12 or 24VDC and the absolute highest DC rating i've found so far is 28V, the problem is that the highest voltage i'm using is a little under 36VDC so where do i find appropriate switches? I've been getting helpful advice about the speaker project from someone on a forum called SpeakerPlans but they seem to think that i'd be fine using an on/off switch rated at 5A 12VDC despite the higher voltage requirements of my amplifier, i'm not very electronics literate but this doesn't make sense to me and i'm a bit worried about pushing too high a voltage through the switch and perhaps causing a fire or something. I would prefer a rotary switch if possible as i used one on my old 12V speaker and i found that it's a lot less likely to catch on clothes and bodies and break or accidentally turn on while the speaker is being manhandled/transported about. I have 2 circuits in my speaker setup, one is the 36V circuit powering the amplifier/speaker and the other is a 12V circuit powering a small mixer to boost the gain and tweak the sound, assuming i can find a switch capable of handling the 36V is it possible to have one switch that could be wired up to turn on both circuits at the same time?

Therefore, I specifically summarise the home distribution box installation knowledge, as well as home distribution box wiring diagram to make the relevant finishing, for everyone to take precautions, the home distribution box has a clear understanding. Home distribution switch installation points 1, Household distribution switch sub-metal shell and plastic shell two, there are two kinds of mounted and concealed, the box must be intact. 2, The household distribution switch of the cabinet wiring assembly should be set up to zero line, to protect the ground wire, phase line, and to be intact, with good insulation. 3, The installation of air switch seat should be clean and there is enough space, should be installed in the dry, ventilated parts, and no obstruction, easy to use. Never install the distribution box in the box to prevent fire. 4, The household distribution switch should not be installed too high, the general installation of the elevation of 1.8 meters, in order to operate; into the distribution switch of the electric tube must be fixed with a lock nut. 5, If the household distribution switch to be open, the edge of the hole to be smooth, smooth, distribution box buried in the wall should be vertical, horizontal, edge left 5 to 6 mm gap, distribution box wiring Should be rules, neat, the terminal screws must be tightened. 6, The loop into the line must be sufficient length, no joints, after installation marked the name of the use of the circuit, the installation of household distribution box to be completed after the removal of the distribution box residue. How to assemble power distribution switches at home ? 1, The installation of electrical box, distribution box installed on the wall, should be used bolts (expansion bolts) fixed, bolt length is generally buried depth (75 ~ 150mm), the thickness of the box floor, nuts and washers Of the sum of the thickness, plus about 5mm of the "margin". For smaller distribution boxes, it is also possible to embed a good brick at the installation site (in the form of a distribution box or a panel mounting hole) and then use wood screws to secure the distribution box or power distribution board. 2, Dark assembly distribution box, distribution box embedded in the wall installation, in the wall when the hole should be reserved than the length and width of the distribution box about 20mm, the depth of the distribution of the thickness of the distribution box with the wall Plaster thickness. In the masonry distribution box, the box and the wall filled with concrete can be fixed to the box live 3, The distribution box should be installed firmly, horizontal and vertical, vertical deviation should not be greater than 3mm; concealed, the distribution box should be around the gap, the edge of the panel should be close to the wall, the box and the building, Part should be coated with anti-corrosion paint. 4, The distribution box installed in the spiral fuse, the power cord should be connected to the middle of the terminal contact, the load line should be connected to the threaded terminal. In this way, in the loading and unloading fuse will not be electric shock. Porcelain plug-in fuses should be mounted vertically. 5, The distribution box of AC, DC or different voltage levels of power, should have a clear sign. Lighting line, should be set to zero line (N line) and protect the zero line (PE line) bus, zero line and protection of the zero line should be connected to the bus, not twisted, should be numbered. 6, The wire leads to the panel, the panel line hole should be smooth without burrs, metal panels should be installed insulation protective cover. Metal shell distribution box shell must be reliable grounding (then zero). Ps: Excuse me if I was wrong in words or expressions as I am a green hand in the field of power distribution switches. I need continual learnings. What is your idea ? Do you agree with my ideas ? Any of your ideas would be highly appreciated. May someone would like to help ? thanks in advance.

LED powering and switches

I am trying to build a small display box that has 2 LEDs (either 3mm or 5mm). One LED lights the displayed item from above, the other from below.  I plan to use only 1 LED at a time, so I presume I need an SPDT-Center off micro rocker switch.  I have a small model and it provides ample light with 2 CR2032 batteries, however, I'd like to be able to use an AC/DC adapter in place of the batteries. I need help figuring out what parts I need so I don't create anything dangerous. I am confused by the terminology used for the switch...how many amps/volts would I need? Am I correct that I would need a 6v adapter? Can the adapter be wired directly to a battery holder, or can it be SAFELY wired directly to the switch/LEDs? I want to order some stuff, but I don't know what I need! If anyone can provide this info, I would be grateful! Thank you.

How to make a Line-In switch for one pair of speakers?

I'm livin with two room-mates and a kinda dream of us is to put speaker cables from each room to a switch and then further to a pair of speakers in the kitchen. The problem is that i only find switches for one Line-In and several pairs of speakers and not the reverse type model. As i dun have any further electronic skills, could sumone give a construction plan or a link to such, so that i know what parts i need to buy for soldering?

Ballerina Jewelry Box Project

Hello, I am interested in creating a jewelry box for my niece. The idea is to laser-cut a custom box which I think I can find templates of online and create an SVG file with some art for the laser cutter. I plan to 3D print a ballerina as well. I initially thought of running the electronics with Arduino - but prefer to keep it simple.  I want to have a custom song/melody playing - I was thinking of perhaps some sort of a recording/playback speaker where I can record the song initially and then have it play back - ideas? For simplicity - do you think it is possible to run a simple circuit with a couple AA/AAA batteries, a hinge control (ideas for something that will do the trick and act as a switch are very much welcome too), a speaker, and some sort of a stepper motor/servo to spin the ballerina. I would love to get some ideas and supplies from you. This should be a pretty straightforward, simple project but I don't have much electronic experience and am not sure what to search to find the technology I need. Thank you, KoMoDo

Good source for foot switches? Answered

I'm looking to build a stomp box of sorts, and am having trouble finding a good source for foot (stomp) switches that will hold up.  Neither Mouser nor Digikey seem to have something appropriate, at least based on my searches.  I found DIYstompboxes.com, which seems to have decent enough prices ($5.00 a pop). So my question is, what's the best (taking into account reliability, speed, quality, and best deal mainly) place to get a foot switch that will hold up without breaking the bank? Also, when I say foot switch, I mean a button.  Not a pedal.

I want to make a wooden music box, where do I start?

I'm thinking about making a wooden speaker box that plays music from one of my favourite games. The box would have an embossed panel with this logo on the front: https://si0.twimg.com/profile_images/1878799410/AnimalCrossingLeaf.png on the top would be the speaker face, buttons to play and stop (2 seperate or a toggle) and a button to switch between playlists. On the back, would be an on/off switch and power cable if it requires one, although I'd prefer it having a battery. So, what wiring/technology would I need? Could I break open an mp3 player and cannibalise it, or would I be better off with a Raspberry Pi, and with the Pi, would the software be hard to make? (have the buttons perform their actions). Lastly, what tools would I need to do this? Thanks.
