Wire Wrapping Kits

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.

Material to wrap a project with?

I am building a project that has dimensions of roughly 2 inches by 2 inches by 1 inch. There are plenty of LEDs, exposed wires, etc. that I want to cover up. Does anyone know of a material that I could wrap this in, perhaps a sort of heat shrink for it all? It does not need to be protect it from being submerged underwater or form a protective barrier for being dropped. Hopefully something a little more professional looking than bubble wrap. Any suggestions would be greatly appreciated.

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!

Wire ribbon roses?

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 remember getting a closer look at it and seeing that the stem was wire as well and wrapped with shear non wire edged ribbon, but i have no clue as to how to make it.... 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?

Rotating Antennae Wiring Question? Answered

Ok, something I've been thinking about for awhile.  Say you have an antennae/radar dish/etc that rotates 360°. Naturally, you have wires running up to the antennae connecting it to the rest of your circuit/broadcasting/receiving device. How do you prevent the wires from wrapping around the antennae and causing it to stop or causing the wires to break? I suppose you could reverse the antennae every so often to prevent this, but there must be a better way. Also, I figured you could have some sort of connection that rotated around, but it seemed that a rotating connection could be problematic if debris or something got in the way. It also doesn't seem like a very solid way to connect the two devices together.  Not actually building something here, just a curiosity. Thanks!

I figure I can do something like wrap it a few hundred times around a pole thats slightly larger than the rare earth disc magnets I got. Anyone have any suggestions? Btw, most of my information is adapted from normal rotating wind power generators.

how to strip large diameter copper wire

If you have say 2 inch or better diameter copper wire to strip here is what I do. I have ben in the scrap arena for years. Buy a large handeled pair of shears that are only for copper. They will look much like a large pair of boltcutters. Cut your insulated wire into about two foot lenghts. Get a large pot, the bigger the better and heat with an out door propane burner full of water. Place the cut sticks of wire into the boiling water fro about five min. Get some insulated rubber gloves and a sharp razor knofe and you will find that the plastic insulation carves away like butter. This works on everykind of insulated wire I have come across. With lead wrapped insulated wire, get a plasma torch. It cutts easily and is so fast the plastic wire inside does not have time to catch on fire. Use plenty of ventilation to avoid breathing lead based fumes.

Connect wires without a solder iron!

Hey guys I haven't created an instructable yet, but I know how to connect wires without soldering.  Its simple and I am thinking of making an instructable about it.  all you need is aluminum foil and eletrical tape. simply connect the wires and tightly wrap them together in aluminum foil. then put eletrical tape around it and there you have it. any ametures(ignore my spelling) like me that dont have a soldering iron can do this.  although it is limited, it is easier than soldering. ill eventually try to make an instructable though.

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?

Help with what type of motor I should get

Ok well I've made a cord/wire reel for a 30m long internet cord, that I use for my xbox 360. I made it using 2 of those cd stacks holders. like this:[=====] II II II II[=====]Then put a cut half newspaper over so that the cord doesn't have to make tiny circles.It's really annoying when I reel the cord back in cause I have to turn the reel or else the cord gets twisted. I cant just grab the cord and wrap it around the reel. If you dont get what I mean then think of it as if you had pack up some string so you grab the string in one hand and use the the other to wrap it around. Thats what I cant do instead I have to rotated the hand thats holding the string other wise the cord gets twisted.So what I thought was that I could either get a motor that reels it in for me and I can also pull it out without damaging the motor or I could use something that you use to reel in a garden hose.The cord and the reel way a tiny bit over 1kg.Any ideas on what motor I shouldget or how to build the reel in thingy.

I broke an LED; will connecting the one wire leading in to the wire leading out break the device?

I have a broken LED. Will connecting the wire leading into the LED to the wire leading out of that one LED break the device? I don't have solder so my plan was to twist together the stripped wires and wrap in electrical tape. Would powering on the device cause any sparks? The LED is part of a group of LEDs in a ring around the cone of a hair dryer. There are wires leading up to this ring-shaped circuit board with six leads and a resistor. Would directly connecting the two wires leading up to this ring-shaped board break anything or potentially be hazardous if operating the hair dryer? Now that I think about it, the electrical tape would not be a good idea as it would probably melt pics: http://i.imgur.com/pSmSvUc.jpg http://i.imgur.com/X7GUoDn.jpg

Re-winding a PMDC motor?

I have a 12V 5000RPM 15A PMDC motor and even at its top speed I can stop it by hand which is just not right. I took the armature out and here is what I found: Its a 2pole with 16 winding slots, each winding is quite large but theirs only 3 wraps! I know if you half the wire surface area and double the wraps you get half the RPM. Currently the rotor has 3 wraps per coil of 18guage wire with easily enough room for 10x that. What wire size and how many wraps should I re-wind this motor to get maximum torque at 2000RPM?

heating coil advice(resistance wire)

Hi, my name is david. im working on a project, for a device that is roughly .25-.5 inches long. im trying to find the right material resistance wire for the application. the components are submerged in coolant to maintain a low temperature. i wish to have a resistance wire of some kind wrapped around the components to heat them to about 90 degrees as quickly as a possibly can, for only a brief time(fractions of a second) i am using a variable power supply to determine my power needs. im hoping to be able to send a quick "signal" through the resistance wire, and use heat as a sort of input/output system. the internal components will melt at temperatures above 100 degrees.  so regulating the temperatures is key.  now obviously since they will be submerged in coolant, the resistance wire will need to heat to higher temperatures in order to heat the other components. ive been doing some research on nichrome and kanthal wire. but from what ive seen so far, it almost heats up to quickly, to higher temperatures than i require. it is hard for me to do the calculations, since i dont know how many watts/amps etc i will be using.  so to recap: temperature required about 90 degrees. (as quickly as possible, "flash heating" to 90degrees would be great) length is .25-.5 inch (the size will actualy be determined by the resistance wire i would prefer it to be as small as possible but i could make the module larger if i have to) variable power supply to determine my power needs(preferably the lowest possible power usage to conserve battery power) any suggestions on an appropriate material would be appreciated. i dont mind testing out different materials. i just dont want to spend thousands of dollars buying a little bit of everything and testing each one out one at a time. >< some experiments have suggesting silver coated nylon, but requires 20watts and a pretty sizable heating time. the heating coil will most likely have direct contact with the components, unless it is required to provide space between the coil and the components to heat it appropriately. i would prefer direct contact though to make the modules as compact as possible. currently the coolant is being pumped continuously through the whole system, but ive been working on plans for a valve to interupt the flow of the coolant during cycles where the coil is activated, if the need arises to keep the coolant from preventing the resistance wire from heating up appropriately.

Simple Zapper Idea

I have learned about electricity in Physics class and that to up the voltage of a given source there has to be an alteration in the amount of turns of wire around some magnets. BUT... is it possible to do this same thing in my home on a smaller scale by wrapping wires around some of my powerful earth magnets? The reason for asking is that I want to increase the current flow so that it starts zapping when the wire ends come near, also I want to create a ground based bug zapper for fun that will allow the zap to travel through water (shallow puddles). Sorry if I'm missing some law of physics that renders this impossible for me but I'm not taking the advanced course for science and we only touched on  the topic electricity.

With an electromagnet, if there's a open reed switch betwen 1 end of the coil's wire & powersource, will e-mag get hot?

I'm building an electromagnet. The core is soft iron: 0.5" diameter and 1" long.  AWG 12 wire OR enameled copper magnet wire 32 gauge So the wire is wrapped around the core. One wire end leads to a reed switch which connects to one of the two wires of the 9 volt snap-on battery clip. The other wire end connects straight to the 9 volt snap-on battery clip with nothing in between. Will the wire end that connects directly to the 9 volt snap-on battery clip: A.) use powers and drain the battery B.) heat up the electromagnet (wire & core) If the electromagnet heats up, then how hot does it get? Just warm or really warm? Could it reach hot or HOT levels - hot enough to burn skin, damage any part of the electromagnet, or ignite/melt the carpet (if it was on it)?   P.S.  The final device would have no exposed wires. Thanks.

How do I make an Electromagnet? And a few questions about them and regular magnets?

   I’m looking to learn about electromagnets and magnets. I looked up all those common videos on YouTube of course but It’s not the same as asking people who can tell me directly how to go about making one and things I can do with them.    Here is what I know about electromagnets so far. I know that you wrap wire around a piece of iron neatly (the more times you wrap the stronger it is). Then you attach a battery to the ends of the two wires that are left and then you have a electromagnet. I also know that to much power is bad because it can heat up. I want to make some cool things with electromagnets. So here are my Questions: Center Of The Electromagnets Questions - What is the best thing to put in the center of a electromagnet? - Is Iron the best and if so what is the best type of iron to use? - If different materials will have different effects could you please list them? Wire For The Electromagnets Questions -What kind of wire works best? -Will thinner or thicker wire wrapped more times around make it stronger? -What is a good wire to iron ratio? Power For the Electromagnet Questions -Could I use a DC wall Plug instead of a battery? -If I use a wall plug could I make a separate Positive and Negative electromagnet? Few Random Questions -What materials will that block electromagnets? Which works the best? -What can you tell me about electromagnets that I didn’t ask?

How to balance a mobile... and attach its parts?

I've always been interested in making mobiles, or at least making the various parts that I would like to balance in a mobile. I've only really made one, which was a real hack job. I want them to look nice, so...two questions: 1) Is there a scientific method for achieving balance in a mobile apart from guessing? In the one that I did make, I used a fairly thick flower-wrapping wire, tied the parts to each end, and then found the fulcrum by balancing it on my finger. This is an awfully rough approach and is only so accurate. It worked okay, but I'd like to know how you've found success in doing this. 2) As far as attaching the parts to the end of the wire, how do you do it? I'm not very happy with the flower-wrapping wire because it's so tender and warps so easily. It's impractical for shipping or moving the mobile. Not at all durable. So what material do you use for the wire portion, and HOW do you attach your parts to it? I've tried twisting loops into the wire, but it really messes up the general straightness of the wire. I've tried tying fishing line onto the wire and adding a dollop of glue. But that's just ugly. If you have a good online source for making simple mobiles, and the materials one should use, I'd love that too!

Hi, I have a trx stand up scooter, how do I wire it, the books useless.

3 batteries, 2 motors, controle module. The module has 10 wires, the black and yellow wires go to the motor with the black and yellow, got that. Two matching wires go to the other motor, got that. The large wire is 4 wires wrapped together and their ends match up to wires coming from the handle bars, 2 prong, 3 prong, so forth, got that , those wires I got snapped together. 1 black wire is left and 1 red. Okay positive and negative, got that. This is where I don't got it. I believe before, the positive went to the positive of the first battery and the negative went to the negative of the last battery. For reasons I don't understand the negative of the first battery went to the positive of the middle battery and the negative of the middle went to the positive of the last battery along with a 30 amp fuse. The on/off switch has 3 prongs( what is the extra prong for?) The charging port has 3 prongs,why? There was a wire with a wierd thing on it, I want to call it a resistor, what's this and do I need it? How do I tie it all together, 1 negative wire, 1 positive wire coming off the control module to the 3 prong on/off switch, 3 prong charging port, 3 batteries (36volt) and a fusable link in there somewhere. All these parts are what the scooter originally had, "friend" got as far as just unhooking everything. HELP, I don't want anything to blow up.

can i use hair dryer or toaster nichrome to make a lead forge?

Hello, a brilliant idea(as they often are) crossed my mind this morning which was to build a 3 in one heating machine. 1. a charcoal maker, heats up wood to the point where it converts to charcoal. 2. burner gas generator. the flamable hydrocarbons released from the sun bleached wood (hite and crumbly, i got tonns of it literally, like moled plane wood), to make fire to reuse for a stove or heater, for something i may want to heat at the same time. 3. lead forge , for melting lead to fill my lead electrode molds, so i can electrolyze in sulfuric acid and then sell, or use, as lead dioxide electrodes for chlorate making etc. Now, butane and propane are completely unreasonable sources of heat, and too expensive as well, so i wanted to know, if the nichrome heating element inside a toaster or a hair dryer, could reach temperatures in excess of 330 degrees Celsius? i want to wrap the nichrome wire , around a steel crucible , separated by fiberglass of course to prevent the nichrome actually touchings the steel, so that when i apply power, the wire heats the steel (which will not be exposed to air) with the nichrome, and therefore heats whatever is inside the crucible , however, i want ti to also be able to reach temperatures in excess if 330 degrees Celsius, so that i can also melt lead. is this possible? otherwise, what kind of nichrome can i directly apply to 240v (wall output) assisted by large contacts for obvious reasons to do so. i know for a fact that nichrome drawing 5 watts is capable of melting lead, as i have melted lead before with my battery powers 5 watt soldering iron, which's soldering tip is a hollow piece of metal with nichrome inside. i want to be sure that this machine will work before i go and buy some second hand toaster or hair dryer at the dump shop. so, will it work? Ive seen hair dryer heating element used before to heat sodium hydroxide inside a steel crucible, in a sodium electrolysis cell, and it went over 320 degrees Celsius. i think. but i cant be sure. i still need a second opinion, thanks

Here are pics of said toroid - http://imgur.com/a/Z0hC8 - I'm planning to replace the wrapped wire, just need advice on what to use to cover up the broken insulation on the actual toroid?  I've tried nail polish, however it heated up and smoked against the bare wire (hadn't yet rewired it when tested). The toroid is on a Power Supply.  Replacing the entire PSU is not an option.
