nichrome wire

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.

Help with wiring

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.

Battery Wiring?

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?

Microphone wiring? Answered

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?

Wiring Question

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

Wiring question?

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!

Dollhouse wiring

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

Wiring help

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?

Induction Motor Wiring?

Hi, I've recently bought a Clarke Induction Motor with these specs: 230V 1 Phase 2 h.p. 1.5 kW 1330 rpm 50 Hz 9.4 Amps Capacitor Details: 50 micro Farads 450 V I have been looking all over the internet on how to wire it up to go into 240V mains (UK) but I can't find a thing. In the terminal box there are 6 terminals labled V1, V2, U1, U2, W1, W2. A brown wire connected to U2 and a blue wire connected to W2 lead off to the capacitor.  A red wire connected to V2 and a white wire also connected to W2 leads off into the motor. Another red wire connected to V1 and another white wire connected to W1 also lead off into the motor. Nothing is yet connected to U1. Please see the pictures which make this a lot clearer. (I have removed the capacitor from the blue catch for the photos) I have looked all over the internet and there seems to be no mention of anything. I basicly need to plug this into mains (therefore 3 wires, live, neutral and earth - obviously earth goes to the motor casing) So which wires go where? Also, the website of the shop that I bought it off said that a 10-16 Amp starter is required. What does this mean/do? Can you just plug it into the mains without this starter. It is probably obvious that I am somewhat of a rookie in motors! Thanks very much in advance for any help!

EL wire help

Hello, I was wondering whether someone could shed some light on this. I'm making a coat with a design in EL wire. I want to use two colors, and I want to have them both on the strobe setting, so that they flash opposite the other.. so one color being on while the other is off. However I may have to use more than one 'spool' of wire per color. I have a bunch of 9 ft. segments already hooked up to batteries.  You may have to bear with me, I know very little about electronics.. But is there a way I can hook up the segments of one color to each other so that they all flash simultaneously? Or is it worth it just to get longer segments/ make my own, and would the battery have to be much larger in that case? Thanks, any input is greatly appreciated!

Wiring a Bubble Machine Answered

Hi I have a bubble making machine which recently had to have the capacitor and transformer replaced. However, I cannot get the machine to run the fan when its all connected. I think the wiring is all a bit of a mess, and I am wondering if someone can help me find a solution to get it to operate again. At the moment when the blades in the diagram are connected to the 3 pin switch only the motor which rotates the wheel for the bubble machine operates, the fan does not work. I have tried others (I have assumed these work but I don't know how to test them independently) but no success. I am unsure if the capacitor is wired correctly either, as reading about it online I have found that one pin is negative and the other is positive :(Also, I swapped the old transformer (see attached) for a replacement led transformer for running 12 volt light, I don't know if this was a suitable replacement.

Question on picoPSU wiring

First time forum poster - Hi everyone. I've just purchased a picoPSU 120 (attached pic) for a custom build and it just arrived today. The DC power arrives through 2 cables (duh :), a black and white one.  For - I'm guessing - extensibility reason, the DC cable is cut in 2 half with a 4 Pin Male/Female connector. On that connector, there's the two cables coming in, and the two cables coming out on the other side - all good. But then (as you can see in the second pic) they also do a weird cable loop of the two cables using the spare input/outputs on the connector. Why is that? I don't quite get what it is meant to do.. ?
