Step 1: Pickup basics

simply a guitar pickup is just a coil of insulated copper wire with a magnet in the center.
most things that seem simple dont always turn out this way but here is an exception(sort of).
now im not recomending that you rip the pickups out of your strat and replace them with the herein mentioned contraptions. but if your building a diddly bow or a frankenstein guitar or just looking to make a new noise then thise is for you

friends may not ask about - about how to make a pick-up coil electric guitar / acoustic

I found your article interesting, but I am wondering how to build these pickups from scratch. The application I am trying to use these for is part of a home made radio controller for robots, so what I need to know is how to build a pick up with a diode or transistor that will connect to an antenna to send signals through the air to the robot's antennas at a max. range of 20 feet away. Do you possibly have information that could be of help to me.

sorry bud thats all over my head.too much math.
if i see anything related to it ill pass it on though

As to the question of polarity of magnets used in Humbuckets, those are bar-type magnets with the North/South poles along the two opposite long Side, not on the Ends , as is the case with a common bar-type magnet.
Since the two coils innermost windings are placed adjacent to each other, those windings are over the opposite poles of this special side-pole bar magnet.
According to laws set down many years ago by Scottish scientist Michael Faraday,
a coil of wire passing through a magnetic field will have an induced current that follows the right-hand rule of current flow created .
It is probably more easily demonstrated by looking up Faraday's Laws regarding magnetically induced current flow. This is the same principal that makes everything from huge generators (think Boulder Dam!), to dynamic microphones, to earbuds, to kitchen mixers, etc... work.
Faraday was an interesting person and greatly influential to modern electronics.
I hope this proves somewhat enlightening and not too wordy! ;)

that makes more sense than my own theories.
thank you for the clarification.

nah its good

I thought humbuckers had coils wound in different directions over each other? Although that is just something I have read several times, I have never had the occasion to actually dissassemble a guitar pickup yet. I'll have to keep my eyes open at garage sales for some dollar instruments I guess. I've changed some pickups, and rewired some guitars, just never bothered ripping a pickup apart yet. Humbuckers do have 3 wires coming out of them though as I can recall. It is good to leave one of the wires detached, in case you ever forget the words!
lennyb (author) in reply to pfred1Dec 14, 2006. 4:45 PM
most humbuckers have the two coils side by side but wound in different directions . some are stacked one coil on top of the other{although that may be just something i heard . ive never seen one like that} the coils need to be separated a little bit so they dont counteract each other. im not sure if those makeshift pickups would work as a humbuckers but its worth a crack if you try it and it works let us know. if i try it ill post it later
lesgibbs in reply to lennybFeb 14, 2012. 1:57 PM
a humbuckers got two single coil pickups wound in the same direction but sharing a magnet there for using opposite poles to cancel out the humm.
lennyb (author) in reply to lesgibbsFeb 14, 2012. 6:52 PM
ahh so thats how it works.
my apologies to anyone i might have confused.

do not mess with coils from tv picture tubes!! tv's can store THOUSANDS of volts even after being unplugged for YEARS!! there's far better safer sources!! ;)
Kiteman in reply to jphotonOct 13, 2011. 5:16 AM
The coils don't store the charge, capacitors do, but it's still good advice to wear gloves and then use an old screwdriver to short things out before you play.
lennyb (author) in reply to KitemanOct 13, 2011. 8:10 PM
crt tubes themselves can also hold a charge for a long time.i got a good zap from one 30 years ago my arm was numb for hours.
lucky it didnt kill me
always wear insulating gloves when handling them.
once the tube has been safely discharged you can handle it then

I like coils from old TV sets, The older the better. If you find an old tube set in the alley, grab it before I do. There are a lot of coils in the old sets, but my favorites are on the neck of the picture tube. The adjustment (convergence) coils are the ones I'm after. They come in 3 sets of 2, 3 sets 'cos they use 3 colors. This gives you one pickup per string, which is exactly what you want for MIDI guitar. If you want hexaphonic fuzz (1 fuzz per string so the strings don't interfere with each other), this is the way. Note that the coils are mounted on ferrite cores, which are very hard, or should I say brittle. Ferrite is a kind of ceramic which will yield to a determined person with a cut off wheel in their Dremel. Just put the whole thing on a piece of magnet. I like the ceramic ones on the back of dead speakers or inside microwaves. More ceramic shaping, but at least you'll learn a new skill.

A quick note:

DO NOT OPEN A TV WITHOUT KNOWING EXACTLY WHAT YOU'RE DOING.

The cathode ray tube can carry enough voltage to kill you even years after the TV has been unplugged. I strongly advise heavy research before you pop open an old TV or, best of all, avoidance of it altogether. (This doesn't apply to newer, LCD, plasma, etc. sets but I would still take caution.)
lennyb (author) in reply to GergoryJan 1, 2011. 7:10 AM
indeed the CRT can hold a charge of thousands of volts for years.
i learned this myself the hard way many years ago.
take all precautions while hunting for useful coils {insulated gloves come to mind} do not touch the neck and side contacts {cathode and anode} at the same time, thats how i got zapped.
charles.david.sutherland in reply to lennybMay 22, 2011. 1:12 PM
the best way to disharge a CRT is to take a lead with an alligator clip and a 1 ohm resistor arrangement and short it out on a ground strap from the cup attached to the picture tube. You should hear a loud pop and perhaps see some arcing when this occurs. You could repeat the procedure to be absolutely sure no charge remains. the problem of CRT's are that it has capacitors with high values, once these loose their charge, it should be plain sailing. Also of hazard is mercury in the tube that could leak if the tube is old or compromise is some way.
chrisreeve in reply to lennybJan 27, 2011. 4:11 AM
Surely if you are taking the tv apart anyway, you could just throw a bucket of water over it. I'd think that should short out and ground any voltage left?
charles.david.sutherland in reply to chrisreeveMay 22, 2011. 1:13 PM
water, not advisable, you could still shock yourself.
Lazy Ape in reply to DrThousandJul 30, 2009. 12:20 AM
do you have any instructables?
crankflip in reply to DrThousandMay 29, 2009. 8:12 PM
Well, I found one out in the woods! how cool is that! :P

i beat you to it last week for that teebee

nice crack man... i cant wait ti try these for myself... keep rocking....long live!!!! =D

Great!!! Looking for a coil!!! Buenisimo, felicitaciones!!!! Gracias!

Do you know if a newdymium n50 magnet would be too strong?
lennyb (author) in reply to johnnyx9Feb 23, 2010. 11:52 AM
im not familiar with the size and strength of that magnet.
but it should still work.
though if the magnet is hugely strong it may dampen down the vibration of the strings some .
let us know if you try it and how it works.
musicman says: Nov 26, 2006. 12:52 PM
hi michael here iv got the pickups made but i dont know how to wire then in to the guitar and everything else.can you please healp me.
lennyb (author) in reply to musicmanNov 26, 2006. 3:38 PM
sure micjael all you need to do is install a 1/4 inch guitar jack and wire it to the ends of wire coming from the pickup i will email to you a diagram that shows the usual configuration. and while those are more complicated than you need it will tell you exactly howit is done.
beatlemack in reply to lennybJan 11, 2010. 5:11 PM
Mack here. Could you also send me the diagram or post it online?
ckurcon says: Aug 20, 2009. 4:22 PM
so could i just get any magnet and wrap some copper wire around it and use it as a pickup? im trying to make a diddley bow and just need something really cheap to use as a pickup
drummer_on_fire says: May 13, 2009. 5:21 PM
What did you put the pick up on? is it a homemade electric stick guitar or stick bass?
lennyb (author) in reply to drummer_on_fireMay 13, 2009. 7:00 PM
you mean in the last picture? that was on a homemade diddly bow. its one string slide guitar commonly used to play blues. as in the famous song ' im too poor to afford a real guitar blues" lol
catter44 in reply to lennybJul 15, 2009. 6:53 PM
where can u listen to that ' im too poor to afford a real guitar blues" song
