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 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.

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?

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'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

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????

Do you ever see those roses at the gas stations that are made of ribbon? the kind of ribbon that's sort of shear and has wire for the edges?

I've been curious for a while but i don't think buying one and ripping it apart to see how it ticks would be exactly sufficient... could someone please make an instructable on this?

Question by SA-DIY 3 years ago | last reply 3 years ago
I know I'm probably going to sound like an idiot for asking, but can magnet wire release any toxic fumes when heated? I made a speaker using a magnet-wire coil and a neo-magnet, and when I plug it into the amp, I realized the coil gets very hot. I was expecting this, for I've used a number of coils in other projects. There is an odor, no doubt, that comes from every coil I've used when making an electromagnet. Sure, the smell may come from the iron nail being heated, but I always associate the smell with the coil. I'm not willing to smell this speaker, however. So, is there any risks that come from the heating of magnet wire? The coil gets hot after about a minute of run-time, but I'd like to be able to run through an entire album of music (an hour?) if possible. Thanks!

I have a desk near my bed with the power strip on the other side of the desk. There's also my keyboard on the desk, so I have no problems in making the wires of my PC, phone, MP3 and 3DS chargers pass behind it so that they are hidden from view. I generally place my PC on the back of the keyboard and charge it, then everything else on top of either it or the keyboard. However, the things on the keyboard are quite ugly to the eye, while on the PC they clog. Also, it's always a pain to take the wire of the right charger (expecially in the dark), given that they are longer than the length of the desk, and if I roll them up they take up too much space. I was thinking of doing something to place those things on the side of the desk and fix the cables there. The problem is, I don't want to drill holes or anything like that, so I'm gonna stick with physics-fixed stuff or tape. What could I do that wouldn't be too bad to the eye?

Hey Guys, I recently needed a laser for a project and as the electronics store had none i thought why non to extract one from a cheap laser diode. So....i got a laser peeled back the casing and got it. But the problem is that it doesnt work. Most probably because one of the contacts doesnt seem to be attached to the laser. Pics have been uploaded. Not that the lower contact doesnt seem to be connected with the rest (p.s it had a spring which used to come in contact with the underside of the button cells. I was wondering if any of you could help me.
Question by SA-DIY 3 years ago | last reply 3 years ago
I need to make a servo wire that extends approximately 4 feet and then retracts to a length of 18 inches or less. There is a risk of entanglement, so the less sag and less loose the wire, the better. One option would be to use coiled wire of the appropriate gauge, but a product such as this is expensive. What are some other options?One idea that I had was to build a wire spool mechanism like that of a tape measure. From what I understand, a tape measure uses a constant force spring to somehow apply a retractive force to the actual measuring tape. Can anyone provide a more clear explanation of how a tape measure retracts? Does anyone have any ideas of how to implement this into a wire spool? Other ideas on retracting a very long wire?Thanks

I can make you a kit for any of my wire jewelry projects. I have the nest and the basic cab kits already, since I teach those, but I can assemble what you need for any of my wire jewelry instructables. Gemstones will be whatever is in my studio at the time, though you can tell me what kinds of things you like. This will hopefully take the anxiety out of not knowing how to get started. Kits usually cost about $3o - $40 plus shipping. Just contact me through instructables if you want one.
