Connection of VERY short nichrome wire? Answered

I have a VERY short piece of 32 gauge nichrome wire that I want to connect to 2 copper wires. When testing, I have connected them like on the picture, using tweezers and a pair of pliers. But I really need to find a more professional and durable way of doing it. It's important to keep as much as "free" nichrome wire as possible in the middle. I don't want to waste all the length inside a butt crimp, or wrapped around the copper wire. Is there a tiny, minitature terminal somewhere, that only steals 1-2 mm of the nichrome wire? Or am I wishing for something impossible?

Connecting a USB?

How would you connect the wires from a USB (female) with wires that are red, black, green, and white, to a 5V boost regulator that only had three legs - Vin, Ground, Vout?  It's not for a computer so I don't think we need the green and white wires, but I could be wrong.  Which wire goes where?  Thanks!

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?

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.

Will a magnet disrupt the flow of electricity through a nearby wire? Answered

I made a removable connection in a project I was working on by soldering the two wires to metal plates and hot glueing magnets onto the plates. This way the metal plates can be brought together and the magnets will hold the plates together so that there is a good connection but I was wondering if the magnets would create magnetic fields that will mess up the flow of electricity. I posted a picture showing the two plates that form the connection I am talking about.

Parallel connection. Am I doing this right?

I am making a mult-point power station where I can connect a few of my devices (max. 5) together. Obviously, the wiring would be in parallel. I am also attaching on/off switches so that the device gets powered only when I want it to. I envision it being used like thus - one or two mobile charging, maybe power a stereo, an LED lamp. Rarely all would be on together but it is a possibility. 1) I wanted to know if I am making the connections correctly. Please have a look at the dig. I made. 2) Also, I am using small 3 way toggle switches because a) They are small enough to fit into my case and b) they look neat imho. They are rated as 3AM, 250V 3) Since it would be a bit cramped I would be soldering the wire to the switches. Is the wiring scheme good, can I use these switches, any further suggestions? Thanks in advance. -Abhishek

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!

how to wire an earphone jack from my bose radio to a speaker 50' away.?

My bose radio does not have an outlet for any speakers I might have. Bose said the only way I could activate a speaker 50' away in the basement is to use a headphone jack wire that is plugged into the Bose. It should transmit juice to the speaker to transfer the sound. I have a breathaudio speaker  with two sets of red and black spring loaded terminal posts. When the jack goes into the Bose radio it naturally cuts the sound from the Bose radio itself and that's fine. I just want the juice from the jack to go to the speaker in the basement to enjoy. Is this possible? I'm working with very fine headphone wires from the jack wire itself to transfer power to the speaker via speaker wires that will attach to one set or both sets of the black and red spring loaded terminals on the speaker. Thanks, Jon Burnham

Potentiometer not working after connected to wires

Hi, I'm fairly new to electronics and I'm trying to learn it with my Arduino. Recently I have been working on a project that involves 4 potentiometer(pot). I'm using one 1k pot and 3 10k pot. The pot is used to send signals to the analog inputs of the arduino. To test the pots I used a simple serial.println program that sends the value of the pot from 0 - 1023. When I connect the pot through its 3 pins directly to the breadboard, all of them work perfectly fine and gives me a stable value as I turn the pot. However, when I soldered three wires to them each, 2 of them work and 2 of them didnt. The 1k and one of the 10k pot didnt work. When I connected it through its wires, the values it gave kept jumping even when I'm not turning the knob and sometimes it will just stay one value when I'm turning it or not. Why is this happening? Did I overheat the pot when soldering? I took some new pots and tested them again through the pins directly and it worked perfectly fine. But when I soldered the wires to it, this time the 10k worked fine and the 1k didnt work. It gave the same problem as the ones before. Please help me with this problem. I have attached the pictures of the pots that didn't work. Please help me check if my soldering is anything wrong. I have checked online couldn't fine anyone experiencing the same problem. TQ!

Avoid wires from touching each other?

I am building a Guitar Distortion Pedal. I have made a case for it. When all of the contents are inside the case - sometimes there are misconnections, and 'scratchy sounds' i get through the amp. I'm assuming this is because some wires are touching OR some wires are NOT touching. In any case, I need suggestions as to how to avoid wires from touching each other. I know there are rubber wire sleeves that can protect the wire from other wires. I've used some of those. But, is there such a thing as a "Blanket"  to lay across the circuit board so it doesn't touch or interfere with the case? If so, please let me know! Any other suggestions would be appreciated as well.  Thank you. - Grizzly_Bear

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!

Make serial connected batteries easy to replace Answered

I am working on a project that requires two serially connected 9V batteries to power.  For when the batteries will need to be replaced, is there an easy way for a user to replace them without having to disengage wires and then solder new ones?  Is there a way to "rework" the typical battery caps used on 9V batteries?  Using an 18V battery is not an option because of the size of the container the battery is being placed in. I was thinking to use two battery caps, one to connect the positive and negative posts to make the two batteries (9V) serially connected, and then "rework" the other cap to connect the remaining posts on each of the batteries to provide power to the unit I'm making. Is there a way to do this ? Is it feasible?
