@@brewmaster243 How do you calculate how many winds/turns you need to put on the coil? I'm trying to find a formula but don't really know what to look for.
Ian, I found a spec somewhere claiming the resistance of 42 AWG wire is 0.892 Ohms per turn. I targeted 7100 Ohms for the neck pick up, which calculates out to 7960 turns. Actual measurement on 7960 turns ended up at 6810 Ohms. I targeted 7400 Ohms for the bridge pick up, calculating to 8297 turns, actual measurement of 7430 Ohms. So that spec was more accurate for the bridge pick up. For the neck pick up, I would use 0.855 Ohms per turn were I to do it again.
I've been debating winding my own pickups for a while now. This gives me the info I needed to go ahead with it. Where did you source the opto coupler? Also, I see you've got some resistors inline with it before the counter. Any insight on that? Great video!
Thank you! The optocoupler is one I had in my parts bin for many years. Any general purpose optocoupler would do the trick. The resistors are 180 ohms, for current limiting, one for the emitter and one for the sensor. I used a 5 VDC power supply. I developed that particular circuit to work with the counter, which requires an open/closed switch contact to register one count.
reed switch, magnet and cheap calculator will work as a cycle count and it's cheap to make. what I wanna know is how these guys who did this already managed their supply spools. lots of people show wire going on the pickup but you never see it coming off the supply spool and I can see me having issues with that.
now I post that comment I get to the part where he shows the supply spool lol. I didn't think that would work so well tbh. I'm wondering if having the supply spool stand vertically above the pickup winder might make things easier... then it can literally gravity feed into the winder
42 AWG is typical for most for all applications. for strat single coils some people use 42 for each pickup, other use 42 for neck and middle with 43 in the bridge.
No, the tip is not new. Don’t crank the iron temperature up higher than needed to melt the solder. And store the tip dirty, and by that I mean don’t wipe it clean after using it. Instead, wipe it clean on a damp sponge just before you use it. Thanks for watching!
Hi! I put 7960 turns on the neck pickup, based on some information that I found somewhere on the internet. Resistance of the neck pickup turned out to be about 4 percent lower than I was targeting. The neck pick up is slightly shorter than the bridge pickup, and I think my calculations were more accurate for the longer bridge pickup. Were I to do it again, based on my own experience, I would put about 8300 turns on the neck pickup to arrive at 7100 ohms.
The wire is AWG 42, which has a diameter of 0.06335 mm, which is very tiny indeed. I don’t think you could use wire as large as 0.6 mm diameter because you wouldn’t be able to fit enough windings onto the bobbin, and you wouldn’t get enough coil resistance. I tried to find a less expensive substitute, but in the end, I decided that spending the money for a roll of pick up wire from a luthier supplier was the way to go. Thanks for watching!
@@nickkall1348 Hi, Nick. I really don’t know how wide it SHOULD be. I based my number of turns on the resistance of the coil that was desired. And to be honest, the coils ended up quite chunky, and it was difficult to get the covers over them. So physical size wasn’t on my mind at the time. Sorry, this probably isn’t the answer you were looking for!
Where do the black and white wires go exactly? I can't really tell by the way it's shot. Black (beginning of bobin) white (end of bobin) or the other way around?
It doesn’t matter which wire colour goes where, but be consistent. If you put the black at the beginning of the winding on one pickup, do the same for the other pickup. Then it’s a simple matter to match up the colours when doing the hookups later, where you might want to call the black wires the “hot” wires, for example. The pickups are reverse wound and it’s important to keep the phase relationship, which is easy to do if the wires are soldered this way. Thanks for watching!
I used a Stewmac jazz bass pickup kit. The pole pieces are Alnico 5. I will say that the kit was less than impressive-nothing would fit together, the holes in the flatwork were too small and needed to be enlarged, and the fit and finish of the covers was about as low grade as it gets, needing extensive sanding to make them moderately presentable. However, I do like the sound. I have finally finished the bass project and I am working on a demo video.
Wayne, my counter module input wants to see a 5 volt low to high transition to register one count. I found an optocoupler in my collection of bits and pieces and used it as a transistor switch on a 5 volt line with a 10K resistor to ground. That signal was applied to the inputs of the counter. Super basic but worked like a charm. Thanks for watching!
What is the counter module input name that you're using? the 10K resistor to ground connects to the optocoupler how so? I'm not sure why you're using a 10K resistor to ground
@@waynegram8907 The counter is something quite old that I had in my stash of miscellaneous electronics components. It is a Redington 5300-0100. The optocoupler output is a transistor, so a basic transistor switching circuit and 5 V power supply was adequate to feed the input to the counter.
I did not make the counter...it is a module that was in my pile of electronics junk. I have no idea where it came from or when it was added to the collection, but I know that I've had it for decades, just waiting for the right opportunity to use it. Thanks for watching!
Hi, Engkus. I did some Googling and a few calculations. 42 AWG is 0.0633 mm in diameter with cross-sectional area of 0.0032 square mm. It’s very tiny stuff.
Nice job! Thanks for such inspiring video!
Excellent work! Very clever use of what you had to get the job done.

Is that a new soldering iron tip? I only ask because if it isn't you mind letting me in on how you keep it fresh?

You deserve more subs
Although background music would be nice, but that’s a nitpick

Well you said that on the bridge pickup are 8300 turns can you tell me please how many turns you did on the neck pickup?

Hello! Excellent video!
Query...what size is the copper wire?
0.4 - 0.6 or failing that it can be 0.7?
The wire is AWG 42, which has a diameter of 0.06335 mm, which is very tiny indeed. I don’t think you could use wire as large as 0.6 mm diameter because you wouldn’t be able to fit enough windings onto the bobbin, and you wouldn’t get enough coil resistance.

@@brewmaster243 Thank you so much! 👍
Hello can you please tell me how thick the copper coil is supposed to be?

It's a way to make a pickup, but it's totally amateurish, today we have ways to do it more professionally, but ok
Where do the black and white wires go exactly? I can't really tell by the way it's shot.
Black (beginning of bobin)
white (end of bobin)
or the other way around?

I try home made winding like this.. but lose the tension.. to saggy .. deperence with the factory so tight winding
superrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Hi! What kind of poles are these? I have been using neodymium and the pickups end up being to bright. Thanks!
I used a Stewmac jazz bass pickup kit. The pole pieces are Alnico 5. I will say that the kit was less than impressive-nothing would fit together, the holes in the flatwork were too small and needed to be enlarged, and the fit and finish of the covers was about as low grade as it gets, needing extensive sanding to make them moderately presentable.

@@brewmaster243 thanks for the reply :D
Too bright means the inductance of the coil is too low (probably you need more windings) - the magnet material influences the magnetic field = output
brewmaster243, does your counter have input ports for any optocoupler? or what optocouple converter are you using to the counters input ports?
Wayne, my counter module input wants to see a 5 volt low to high transition to register one count.
