I am rewiring my guitar, and on regular single-coil pickups, there is two wires, but on my humbucker, Three wires come out, a ground, a white and a red. and all my schematics have nothing to say about three wires being soldered. and i have a five-way switch, with eight hubs. i just dont know whereabouts to put the third red wire. please help

I have new Li-ion batteries for my mac but i wasn't completely sure on how to wire it up to the old circuitry. I know that "vg" is the ground and the "vp" is the positive. I am assuming "vl" goes to the wire "vl" i dont know what that is thought. But there is a "vh" spot on the new battery but on the old circuitry there was no wire going to there? Do I solder that wire there? There is also two very thin wires labeled ntc, i can not find a spot on the old circuitry for that is it necessary?

When I visited MITERS last month, someone was giving away their entire collection of Wired Magazine. I happen to have a current issue in my bag, and it was fun to compare their relative sizes. It's interesting that I also happen to be wearing a Digg shirt in the picture...

I have a broken microphone. Its wire is cut inside the insulation. i want to replace the entire cable. when i removed the plastic cover of the microphone i saw a red and a black wire soldered to it. Therefore it uses only 2 wires but in the connector it is a TRS one not a TS one. i will also replace the connector. i am wondering how should i wire a TRS connector which has 3 leads. one being the common ground. but the other 2. should i short them out and connect the red wire or must I connect the wire to only one lead? 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?

So I was trying to do some wiring with headphone jacks, and i must be doing something wrong. I have a speaker that the cord ripped from, and I wanted to attach a new jack, I cut off and stripped both wires, so there was a copper one and a colored one, why dont they work when they touch each other?

I got some nichrome wire off eBay, and it works great but when I connected it to a 9 volt battery it barley got hot, then I attached it to 4 x AA batteries and it got red hot. why is this? I don't understand because the 9 volt gives out 9 volts(duh) , but the 4x AA batteries only gives out 6 volts.

Cutting open transformers (you might call it an adapter, or charger) yields a good quantity of re-usable magnet wire. Motors don't seem to be a very good source, since the windings on those seem to be saturated in varnish to glue em together. Apparently, vibration is more of an issue in the motors, so they make the windings solid. This might be different in little hobby motors. Dunno.

I have an 8th grade science class (I'm the teacher) that I would like to have construct underwater vehicles. The kids will be using 9v batteries, switches and assorted other materials. Does anyone know of any good books/articles that explain the basics of wiring, electricity, motors, switches, etc. that I can have the students read to get a good base of knowledge in the basics of electronics? Thanks!!!

So I'm working on a heart sensor, and pulled out the wires. I think I can fix it with a little bit of solder, because after 20 or 30 minutes of negotiating, i can usually re-establish the connection to the sensor. But I tried just now, and it isn't working. Help??

Ok, I recently purchased a Go-Ped for practically nothing, and I really, really, really want to fix it up. I want to mount a couple of LED powered bicycle headlights on the front, and a tail light on the back. However, I want to be able to turn them all on and off via a single switch, mounted to the handlebars.I know very little about wiring, but I do know that most bicycle lights require physical pressure to power them on or off. Maybe there's something that can go between the batteries and bulbs?Any input you can provide would be fantastic!-Ryan

Ok i was wondering if i took a microphone that was real cheap from walmart and take the male part off the end of it and put a female part so that way i can plug in a dual male sided cord to it and then to my computer, more or less im wondering, can it work like that? and then i was wondering if there is a program that when i plug the mic in that it works like plugging a guitar into an amp, as in it plays the input to the computer outloud without being in playback from a recording

Hi everyone. Long time visitor of Instructables, made a few items I've seen and my most recent project was adding a star power pedal to my guitar hero controller. I bought a audio extension cable with a male and female jack, 1/8th size. I cut the cable about six inches from the female end. I stripped about an inch, inside was a bundle of copper wire wrapped around a clear insulted wire. I twisted the exposed copper wire and tinned it, I stripped the clear housing and twisted it, tinning them as well. I tinned the exposed wire to the GND, and the clear to Select. Positioned the jack and everything went well. I took the male cable, connected it to momentary switch and connected the male cable to the female jack. Turned on the system and controller. Got star power and hit the switch with no response. I'm very confident in my soldering and know I did it correctly, so I was wondering: 1) Are these kind of cables capable of doing what I intend? 2) Maybe the GND or the Select button are shorted out on the board of the controller? Thanks for any help everyone!

Hi All. I'm a believer in the idea that anyone can do anything with a little info. But I'm in need of a little help. I'm building a dollhouse for my niece and would like to add a little higher-tech slant (she won't be playing with this for a few years yet...) I would like to add LED lights (which I will make but just have to wire for at the moment), a flicker fireplace and a door bell all on wall mounted pushbutton switches. Feel free to suggest anything else that might be cool for a kid... The whole system will run on a 12V adapter but since I need to wire this NOW so I can continue to build, I need a drawing or schematic of how to do it. I've attached a pic of the house and have been pulling apart some of the small flicker Tealights to kitbash into the fireplace. I have a number of white LEDs with which to make the lights but they don't have to go in right now. I know I'll need some resistors - where do I place them? Hide them in the walls? On each switch? Anyways - any help is so appreciated. She'd never get anything like this unless I made it for her - I just want it to be so cool that her brothers are impressed! Tbird

I have disassembled an old vacuum cleaner that runs on 240v/5amps/1200w. I wanted to obtain the electric motor that should perform at 1.5 horsepower. As I was taking it apart I forgot how the switch leads were originally configured. I want to give the motor a test run but I don't want to hit the fuse in my house so I was hoping someone can help me plug the switch in the normal configuration. What order do the brown and blue plugs (that comes from wall plug) fit into the switch? And what order do the blue plugs (goes to motor) fit into the switch? A silly question really but I am new to working with electronics.

Hi guys I am need of some advice and help if possible, I will try and explain as clear as I can. I have a lockup which I have modified to use locking bolts on a motor and I have a swipe card reader and pcb which when swiped it fires the output to power the motor (6v) which works perfect for 6 seconds of the locking bolts going in and out. I am looking for a way so when the locking bolts go to the locked position it hits some kind of limit switch and stops there (which I have done in the past) but then I want to be able to swipe my card to open the bolts and when it gets to he open position it hits another limit switch and stays open until I want to swipe and close the locking bolts. I don't want this to be timed I need this to stop on open and closed position but able to operate when either is pressed, Can this be done in anyway?

AI have a millermatic 211 which is a multi-voltage welder which I will be bringing to the Philippines. The adapter plugs are 5-15p (120v), and 6-50p (230v). Philippine electricity mains when I live are 220v single leg, with neutral. I am adding ground to both the Main panel and sub panel when I arrive, as most residential homes with a 2 wire system do not have them installed. According to the welder schematic 6-50p adapter configuration shows white, red, and green (ground) so goingfFrom a 3 wire US to 2 wire Philippine system is it proper to wire L1 to red, neutral to white and green to ground? 6-50 receptacle does not seem to incorporate a ground in typical installations????
Question by Antonioo35 1 year ago | last reply 1 year ago
So I have recently purchased an 8 inch subwoofer from a garage sale, wich was already mounted in the box. It has 2 inputs, a red and a black. I currently have it hooked up in replacement of the stock passenger side rear speaker in my 1999 ford ranger XLT, and it works well, but is not very loud. My question is 2-fold. 1: how would I go about wireing the speaker so that it could be used in addition to both the stock rear speakers without decreasing sound quality or volume, and 2: How could I increase the volume of just the subwoofer without affecting the other speakers? I have heard that there are "bass amplifiers" that i could hook in line but have not seen where I could purchase/ build one. Schematics and links would be very helpfull! Thanks, Iloveairsoftstuff

I am going to be hand-wiring up a large lot of transformers. Someone has told me there is an enameled wire (magnet wire) whose coating melts when you dip it in solder (also tinning the copper tip at the same time). What is this type of wire called? I am having a hard time searching for it. Thanks!

Hi all, I have been trying to extend my laptop LCD wires to move it away from the laptop,as it only has about 15cm reach at the moment. It is very hard to do as the the wires are very tiny.It was going ok until I ran into a problem with the last four wires.The last four wires are small enough as it is but when I riped off the ends I found that there are two wires inside and some metal wire stuff around them. My problem is i'm not sure if the metal stuff around the two wires (white and purple) is a wire aswell or if it's some sort of protection layer? Another question I have is,will using bigger wires to extend the little original wires cause any harm to the signal? Here is a couple of pics to help. Cheers for any help!
