Step 4: Riggin' up a pickup winder

There are a lot of things you can use as a pickup winder. You could use your hands, obviously, but that can be kind of slow and inaccurate. You could also use a drill or electric screwdriver.

I chose to use a sewing machine, mainly because it's really easy to rig up and use. On the side of all sewing machines there is a wheel type thing that spins around. This is where you want to secure your bobbin. I'm not sure about other sewing machines, but on the one I used there was a small, short screw on this wheel. I removed this and stuck a longer screw through one of the holes on the bottom piece of my bobbin and secured it in the wheel.
Is it possible to make a pickup smaller? like with only 2 bolts instead of 6? I'm planning to make a custom spring guitar and I need individual pickups that are smaller, sorry if this is a stupid question, haha
If by bolts you mean screws, 1 screw is for 1 string, 2 for 2 strings...
<p>two nails, a piece of neodimium, copper wire from a cellphone charger and plastic from the same charger.<br>I've just tested it over my guitar. It sounded very low but i can say it works.</p>
<p>so you connect the pickup to a jack or what?</p>
It appears that way!
<p>wow this is great, inspiring. can you help me on how to construct a ten string acoustic guitar. thanks</p>
Your tutorial is the best...<br>Simple, understandable, easy. <br>a big Thanks from me and a big Like !!!
<p>A humbucker pickup cancels the noise hum by having opposite polarity magnets. Can you just stick a magnet behind a single coil to get rid of excess noise? Anyone know? I know in a strat for example they reverse the polarity of each pickup to get rid of some of the hum. Why can't you just use a magnet?</p>
<p>@paulmusic76: I know this is pretty late, but no, you can't just stick a magnet behind the coil.<br><br>The basic principle behind a humbucker is that you have 2 coils in close proximity, so they are subjected to roughly the same external electromagnetic fields that cause noise (60Hz power hum). By wiring them out-of-phase (&quot;backwards&quot;) to one another, that noise is cancelled- the noise in one pickup is generating a positive signal, and the other is generating a negative signal. By flipping the magnets on them, the &quot;signal&quot; (music) is inverted again (once by backwards wiring, then again by flipped magnetic field). Flipping it twice (from heads to tails to heads) means the music signal is now back in phase, so the music signals from each pickup add together instead of cancel.<br><br>That's why a humbucker has two coils and two set of magnets. If you have another magnet, you can verify that one coil has the north pole pointing towards the strings, and the other has the south pole.</p>
<p>Darn - should have read further up the thread.<br>You said a more technical version of what I said!<br><br>Oops.</p>
<p>Thanks, StevieW! Nice clarification of principles, which will help many experimenters to avoid some pitfalls.</p><p>Just thought I would elaborate a bit on the subject, now that it's brought up. (Bear in mind that I'm just a player, &quot;jack of the trade&quot; when it comes to electronics.)</p><p>There are &quot;split coil&quot; pickups with <br>single coil footprint and sound, reportedly maintaining nearly as good noise <br>cancellation as a regular humbucker with parallel coils. I believe some <br>Fender basses even come with that kind of pickup in the standard setup.</p><p>The <br> split coil pickup designs I have seen use one coil and one magnet (or <br>set of magnets) for each half set of strings, with the reversal of <br>magnet polarity and coil winding direction like on a regular humbucker. </p><p>(Split coil pickup should not be confused with the &quot;coil split&quot; feature available on some <br>guitars, which disables one coil in a humbucker, effectively <br>transforming it to a regular &quot;noisy&quot; single coil. Also, do not confuse <br>it with the coil tap feature, where you have the option to use only part <br> of the coil to achieve a different sound. Be aware that there is a confusion of terms, so make sure you know specifically what is addressed when you do research for your own project.)</p><p>I suppose you could make a <br>pickup with individual coil for each string, alternating magnet polarity <br> and coil wind direction along the pickup. Sounds like a lot of work, <br>and balancing the output of the individual coils may turn out to be a <br>problem. Also, to get the sufficient number of windings on each coil, <br>you may need even thinner wire, which makes the job harder and also <br>increases the risk of pickup failure. I don't know whether such a pickup <br> is commercially available, but I wouldn't be surprised. In any case, it <br> would be an interesting experiment. </p>
<p>What they're doing here is using the opposite phase of the other pickup to essentially double the strength of the &quot;signal&quot; without doubling the noise.<br><br>Just sticking a magnet on will possible strengthen the magnetic field - increasing your &quot;signal&quot;, but also the &quot;noise&quot;. It will pick up noise from low-frequency external signals even more strongly and be louder.<br><br>You've got to make sure the windings on the two pickup coils are opposite directions...</p>
I dont understand the magnets. Im building an electric violin, and i know my way around electriciy, but i cant see why adding magnets would change anything. could someone please explain?
<p>Hello!<br>Guy with Physics degree here - plus guitar player!<br><br>:)<br><br>Moving a ferro-magnetic metal object into a magnetic field (i.e. nickel/steel etc) creates current - the same way that applying electric current to a ferro-magnetic object in a magnetic field creates a motive force (an attempt to move, in layman's terms)<br><br>OR - wiggle a object which can become magnetic in a magnetic field and it generates electricity. <br>The frequency of the current (it's direction if you like and velocity) is directly relative to the change in the magnetic field - or how much and how fast you wiggle the object.<br><br>In this case: the guitar string.<br><br>It's a lot more complex than that, but who wants complex at this stage?<br><br>Wiggle in a magnetic field - makes alternating current (which is how microphones, pickups and generators work.)<br>Alternating current in a magnetic field - makes motion (which is how motors and traditional speakers work)<br><br>By the way: this means a small speaker makes a (very poor) microphone. A traditional (i.e. magnetic old-school) microphone also makes a (very poor) speaker.<br><br>Try it with an old set of in-ear headphones - they WILL pick up sound!<br>(and it will sound pretty awful, but it's hardly optimised for microphone use of course :) )</p>
What DK69 said is right, the bobin core must be magnetizad to sense the strings movement. you are probably confused if you know that a bobin whith an iron core works as a magnet, but it needs a AC to generate the magnetic field. in this case what you are doing is generate that AC by changing the magnetic field of the magnet by the vibration of a string.<br>and i would like to know haw it worked out to place a magnetic pickup on a violin, because i play the cello and i've heard that pick ups don't work well in this kind of instruments, but i have never seen one.
<p>on violins, violas and cellos using non magnetic strings you need to use a transducer style or piezo style pickup, magnetic pups wont work. with that said transducer and piezo pups are available for those instrument and it would just be better to buy one than attempt to make one ( not even sure if it is possible to DIY a piezo pup</p>
<p>Magnetic coil pick-ups only work with steel strings, or any string made with a ferric material (iron based metal). With nylon, plastic or cat gut strings, lol, you open up a whole nother world. A little history, Les Paul once electrified a guitar using a phonograph cartridge.</p>
the magnets set up a stable magnetic field through the windings, the screws concentrate the flux lines beneath the individual strings, the strings(must be metal!) vibrate causing vibrations in the magnetic flux which is transferred to the coil of wire giving a voltage output, but this must go to a high impedance input(amplifier). Too low an impedance, like resistance will load the coil and reduce output, its all similiar to hor a generator works
<p>How could I plug the pickup to amplifier? Is there any problem? Have I make preamplifier or anythink else?</p><p>Thanks very much</p>
<p>Is there any way that we could get a demo of the sound??</p>
<p>So the magnets go on the bottom of the pickup?</p>
Can I use metal for the bobbin plates? I work in a fabrication shop and have access to all types of metal. Or does it have to be non-conductive
What are the dimensions of the pickup?
will t work if i use 37 gauge copper wire??pls help...
how many winds should i do??37 gauge wire <br>
8000 to 10000
a good coil is from 8000 to 10000 rolls. have fun !!!
<p>150 degrees is best temperature when potting. I have not used potting method on my last few pickups but did use tape, wrapped in twine and then waxed the twine to keep it from undoing. Those worked great. Potting would be the normal routine though when making DIY pickups.</p>
<p>does the amount of copper wire matter very much</p>
<p>Yes, Too few and you will get low output and a week sound. Too much is the better. In the 60's some pickups ended up over and under wound. If you get and over wound one it could lead to a unique sound and some specialty companies sell them that way. Shoot for the middle though. I think 6 string single coil pickups have about 8,000 winds. A counter would be good but if you don't have one, ebay sells wire with 8,000 winds on it. Hope that helped. </p>
<p>Before you go through all the trouble to make this and short out your coil to the screws, wrap some tape around the screws just like you wind the wire (around ALL screws, not each).</p>
<p>you need to have glazed wire for this to work</p>
<p>Here's a link for some cheap neodymium magnets:</p><p><a href="http://www.magnet4less.com/" rel="nofollow">http://www.magnet4less.com/</a></p>
Where did you get everything from ? How much did it cost? Could please make an able on hooking them up.
You could mount this in a cigar box guitar <br> <br> http://www.instructables.com/id/How-to-Make-an-Electric-Cigar-Box-Guitar-for-25/
can i use bar magnets instead of these super strong magnets?????
If you're going to use screws, you can make spacers out of bic pens. Just remove the ink pen tube and cut down the white plastic tubes with a hacksaw.
I'm planning to make my own pickup for fun. I wonder if you can just use a variable speed drill mounted in a vise, if you're pulling the wire from a spool. Nobody I know has a sewing machine. Be careful though, wires can slice! Maybe put a stick or big screwdriver through the spool of wire to keep your hands clear.
What I've learned from experience and through some research: <br>The more windings you put on, the stronger the signal output, but higher frequencies will suffer. <br>Thinner wire cuts highs more than thicker <br>Tall skinny coils give a cleaner sound and shorter fat coils sound more &quot;dirty&quot; <br>More wire = greater resistance measured by multimeter <br>3-6 K ohms = clearer tone <br>9-13 K ohms = loud heavy tone <br>Just a word to the wise. You can customize, and experiment to get exactly the sound you want <br> <br>
Hah wow never thought of that
1.can I do my windings directly on the screws for humbucker pickups? 2.is it so that i should use a 44 gauge coil and not less gauge than tat.... what happens if I use a lesser gauge coil than 44' mann? 3. how'll i know that I've done 5000 windings on my screws? 4. watz the difference bet the single coil and the humbucker pickups buddy....?
The main difference between single coil and humbucker pups is that, for the purpose of canceling the unwanted noises like hum buzzes and interferences, the two coils in a humbucker pup are opposite to each other. In the first coil of the humbucker, the poles have the North pole up, and the current goes in a clockwise motion through the wire. In the second coil, the South pole is up, and the current runs through the coil in a counter-clockwise motin. That makes the two magnetic fields cancel inteferences from other eletromagnetic fields. And, due to the number of windings on the wire (wich ads up since they are connected to each other) it has more output, and a more &quot;fat&quot; tone. That's basically it, there's a lot of physics behind pups, and even a small change in one of the steps can change drastically the tone you'll get. That can be very bad, or awesomely great!
So, would you need to wax between winds or separate the two coils in some way, or is the opposite wind enough to dampen the field (if that's even the right term)?
1. yes you can.<br/>2. You can use a thicker gauge, but try and get the thinnest you can.<br/>3. You can count your winds, but I just put as many winds onto the bobbin as I could.<br/>4. A single coil is only one coil. A humbucker is two single coils wired together to &quot;cancel&quot; (reduce) the hum.<br/><a rel="nofollow" href="http://www.seymourduncan.com/images/products/electric/stratocaster/SSL-6.jpg">Single coil</a>Single coil<br/><br/><a rel="nofollow" href="http://www.gibson.com/press/gear/PICKUPS/Humbucker_db.jpg">Humbucker</a>Humbucker<br/><br/>
Yup leperello nailed those questions, but I bet too much smaller would make a huge pickup too, but hey Leperello I just wanted to thank you for putting this up, very informative! Theres a site build yourguitar.com/resources/lemme/ that has some good tech info on pickups ( I didnt see the main page stuff just linked to the pickups) but I needed the basic dig in and tear into it concept down, before I rebuilt my pickups, so thanks for taking the time to post this!
a humbucker is a type of pick-up that is bigger and louder and its like two small normal pickups put together so they work together one makes it more clear so it doesen't have as much fead back and the other is like a normal one so thats how it works "BUDDY"
It's nothing to do with feedback, it's what freestriker said, it's to do with cancelling RF hum caused by... lots of things.
a humbucker is a double coil pickup the two coils make sounds like hum buzz disappear in single coil pickups if theres is a radio or tv near the pickup make those sounds
