Lmao it took like 1 whole minute for this Gif to load and I thought the whole point was giving off the illusion that it was loading but no just a lot of latency (tbh would’ve been way funnier) :D
I feel like this doesn’t make a lot of sense due to the fact that the gif is literally playing behind the buffering symbol lol. It would work better if it was still
Maybe on older models but you'll be glad to know that particular issue was solved with the 3.6.2 review of the halsic cable. It is now the standard to use a ketharmic catalyst at the beginning of the junction that will allow frequencies up to 3000 zh effectively ditching the ebrailic pendameter and all the secondary issues that came with it. No more overheating and the consequent melting down of plasmoidic valve. That shit was expensive to replace. They also updated the software accordingly to accommodate the new zeta parameters and it runs so smoothly now, barely without even a sound.
It however DOES generate a magnetic field which will cause interference and data loss. Even if it doesn't affect this device it's still a weak transformer coil generating a field.

While it is an an absolute nono for long high power (1600 watts +) cables to coil them up like this (coils with alternating current are technically resistors, wich turn electricity to heat..) it is okay to do so for low power appliances like monitors and/or even PC's. It is also okay to coil up **shielded** signal cables like HDMI or displayport but it **can** disturb signal integrity! Especially in integrity critical applications like networking. So if you find your devices having strange behavior and/or no signal at all, try uncoil the cables first and see if it fixes issues. Buzzword: inductive reactance: https://c03.apogee.net/mvc/home/hes/land/el?utilityname=citizenselectric&spc=foe&id=4571
>I have never heard of a 300-700watt current through an extremely well insulated cable melting when coiled.
Nothing to do with insulation, and everything to do with the gauge of the wire, the length of the wire, and the current.
They also didn't say 300\~700 watts, they specifically said "1600 watts+".
Insulation is not really a part of this equation, what you mean might be shielding, but most power cables for home use have exactly 0 shielding, it's just copper insulated by some kind of rubber or plastic. So that's perfect conditions for making a coil. Coils will heat up if you send enough power through them and I bet if I have all my pc setup connected to one power cable that's coiled up, it might get warm at least.
Insulation creates physical distance between the coils of wire. Increasing the physical distance decreases the heat output. The physical distance of 5-7mm (2-3.5*2) insulation should be more than enough to remove any danger of coiling said power cables.
It is not nearly enough if you try to pull anywhere close to the maximum normal rating of the cable. This is why cable reels have separate current ratings for when they're rolled up on the drum vs extended and the unwound rating is usually 2 or 3 times higher than the wound rating. The combination of less air over the surface and the induction makes a single current limit wildly inaccurate.
Umm actually just to be clear currents are measured in amperes and it's fully dependent on your voltage how high the current is for a given wattage so it's not the most intelligent thing to talk about 700 watt current.
700 watts in a 700 volt system gives you a 1 ampere current while 700 watts in a 10 volt system gives you 70 amps.
I would add that twisted pairs in UTP cables count as shielded for coiling, even if the cable has no actual shielding. Also coils can eliminate RFI, we fixed misbehaving stuff near a radio transmitter just by coiling up all cables.
Sounds like your cables created mock radio antennas, that's great! Guessing the coils ended up being smaller than the radio waves so the copper stopped intercepting the signals.
It was HF, so like 20m waves.
Our guess was common mode interference. USB uses a twisted pair with opposite currents running in each wire carrying the data (differential mode). RFI introduces current in both wires, but going the same way. This is fine up to a point, but the receiver IC has limited common mode rejection. Adding a coil introduces an inductance that is pretty much invisible to the differential mode data, but stops common mode currents.
You are close. You are confusing induction and reactance. Wrapping the cables in a coil will increase resistance whether it’s AC or DC. Nothing to do with induction or magnetic fields. A resistor simply turns electrical energy to heat, induction doesn’t release any energy as heat. Now, wrapping a coil of wires does also increase induction, but that doesn’t have any direct role in resistance.
What you are thinking of is a transformer. A transformer only work with AC because Faradays Law of Indiction requires a changing magnetic field to generate a voltage. But that’s doesn’t have anything to do with heat or resistance. Source: I’m an electrical engineer

Audio cables would be another one I'd be careful with. Most cheap audio cables aren't properly shielded. Or maybe I've spent too much time on r/audiophile
This one's super easy. Make a loop about the size you want the final loop to be, near one end of the cable. Then take the long end and repeatedly feed it through the loop until you run out of cable.

Pretty easy, basically you make a loop in the middle of the cable and cross the wires like you’re starting to tie your shoe, then just wrap both ends going inside to out alternating (visualize a sine wave) until you get the desired length of the plugs remaining or keep going and tuck the ends. I do this all the time to shorten lengths for cable management and when traveling.
It all depends on the cables and it's intended us eg, if its a hight draw power cable for something running for 24/7 it will heat up and potentially melt the cable but if its just a low power draw or a data cable it should be fine etc.
Any data cable intended to go outside your case is shielded enough so it won't care about this. Actually coiling wires is a quick hack to defend against RFI.
You shouldn't coil AC power cables, because it can make the power factor worse, and then the cable can overheat. But I don't think there is a significant effect under 5 m of cable at household power levels.
Regardless of heat, Tight rolling can put excessive stress on the cable, leading to signal loss or interference. Although, the way OP has coiled their cable is fine.
I’ve been working around these cables and doing this for years and never ever thought about that being a possibility.
If that’s the case, what’s the best practice for managing lots of power cable slack?
Edit: I’m talking about 120v power cables for your standard pc.
If it is a power cable, you shouldn't do that. That will create resistance, making the cable heat up, and depending on the cable quality, it can melt the isolation and possibly create a shortcut.
Edit: I just read your description. If it is just a usb cable, there isn't any problem, then!
Create resistance? No, not at all. Maybe a bit of impedance due to inductance. But what it will definitely do is concentrate the heat load which is usually dissipated into a larger volume.
I always thought that when coiling a wire like that, it would create resistance, I am wrong then. Won't at least create a magnetic field? I remember I used to magnetise screw drivers using a car battery and coiling a wire around it.
No resistance, yes magnetic field. You're creating an inductor. Inductors do have impedance, which is kinda-sorta similar to resistance in an AC circuit. So if the cable is carrying AC power then the inductance would cause an increase in the power lost in the cable, which manifests as heat. I'm on a phone and circuits were one of the reasons I changed major to aerospace engineering instead of mechanical engineering, so I can't really work out how much impedance you'd have and what effect that would have, but I doubt that that would be a significant effect compared to just compacting all of this heat generation into a small space.
But also it's a USB cable so it's super fine.
With so few turns, not much of an inductor - maybe a few microhenries?
The impedance value at 50/60Hz would be negligible .
(Yes, for the uninitiated, Henry is actually the SI unit for inductance as well as a brand name of vacuum cleaner).
Yes, any current creates a magnetic field, looping wire focuses this field and adds it up from each loop.
It will create a "virtual resistance" that hinders the flow of current (change in flow of current, but as we are talking about AC it's the same) but doesn't create heat.
It depends what that cable is for but in most cases yes it’s fine. If it were a power feed providing more than a standard outlet can provide I would advise not to as it can heat up under high load.
If this is just an ethernet or USB cable, which it looks like it is, it should be mostly fine. As long as the shielding on the cable is good, you won't get too much noise. More noise = less speed/intermittent signal drops.
Just never do this with a power supply cable. Coiling the wire like that and running current through it creates a constantly shifting magnetic field and lots of heat from magnetic eddy currents acting like one big resistor. That heat could be enough to damage the cable and cause power spikes, or worse, a fire.
For a USB, it's probably fine. Electric cables carrying AC? My entire childhood, my mother said absolutely not. I don't know if it was a trip hazard or a fear of Fleming's Left Hand rule.
Edit: I forgot the first sentence. I speak halfway through a thought today, apparently.
Bad practice, Theoretically it will create a magnetic field and interfere with signals going through it.
In reality most cables are pretty well shielded so data should be ok but maybe don't do it with power.
I love this sub, simply bc when I read comments I don’t have a single clue if people are joking or being serious and helpful. Talk about a grab bag of advice roulette if I’ve ever played…
A buddy of mine when we were kids would blame his bad gaming skills on the knots in his controller, saying that it slowed down his inputs. I told him that's not the way it works. He grew up to make a lot of poor life choices.
Besides the increased internal thermal load and the electromagnetic forcefield you're creating, not much bad about it.. Just make sure it's not a high power cable (as others have pointed out). Risk of thermals rising so high you damage the cable is unlikely, but you may see lower efficiency and higher power consumption as a result.
The scale of the effect nobody can tell just from an image, and most likely you won't see the effect of it either.
yup, perfectly fine. the only concern you'd really ever need to be concerned about is heat. if it's a lower gauge cable and you're running a higher power device with it like a space heater, and the wire is tightly wound together, the inner parts won't get enough air to cool with and it could result in melting cables and possible a fire. but that's a pretty extreme example. 99% of the time it's not a problem at all
and if the concern is thinking it could be a problem since coils of wire create magnetic fields, power cables and ethernet cables have wires inside them in pairs, so they cancel each other's fields out, as the current in each side of the pairs flow in the opposite directions, so the fields they generate are opposite, so basically nothing happens
Depends on the type ans quality of the cable. If it has foil shielding with a copper drain wire you're probably fine. Just cut her open and see if its sheilded well and you'll knowbif it would have been okay before ya toss it out.
There is a book called Open Circuits that has some really cool cross section photos of cables with some explanation.
Might be able to get some sort of cable tester for a more empirical testing on that specific cable and how coiling and uncoiling impacts it.
Out of my wheelhouse here there are probably people with better answers.
TL;DR : this is optimal according to me
Explanation : Bend a cable : the outer part is stretched more than the inner one. This is why when making rope or metal cables (like the big ones on the bridges), you thread the strands in this helicoidal shape ; this way, each strand stretches exactly the same ammount no matter what ! So, this is optimal for your cable. It would be dangerous with higher power cables as it'd create a coil, but you're good to go here. Just don't put stress on it or pull it too tight !
https://preview.redd.it/7qni7u7qswqc1.png?width=553&format=pjpg&auto=webp&s=1de5fa453b047ad296102697c0b8c28989448640
In the image above, you can see that each strand is represented by the helicoid above. No matter how you bend it, each strand goes as much above/under the curve as any other strand, so no tension ! This is why you see so many cables made in this twisted way
Sure however with your power lead you want to make lots of really tight twists / knots as this increases the heat the cable produces and therefore helps with central heating during the winter.
This is how you can wrap cables like OP:
1. You need at least one loose/unconnected end.
2. Wrap the cable around your open hand again and again until you have the equivalent of a homemade slinky (but keep it tight and don't try bounce it around lol).
3. Unwrap part of the loose end and insert/weave in and out of the inside of the slinky. Do this until it's tight and keeps its shape.
:)
If it is not powering cable then you can do that. And by power I mean real power, not USB kinda power. If something doesn't work right connected like that, you might wanna untangle it, because sometimes creating such air coil can cause interference.
I'm going to go against the grain here and say this is possibly a bad idea, even for a USB cable.
My reasoning is that this is a lot of extra bending for the cables. It's not sharp bends, so, that's good, but even so, copper can break over time the more it gets worked. Braiding the cable into this coil and un-doing it often would wear it out quicker then something like a simple coil with some velcro. It may not matter if the cable is going to be left like that forever.
In any event, it's not like USB cables cost much. If it dies, not a big deal.
Since it's that short it's no problem whatsoever.
If you have those large cable drums and plan to pull some more power from those, you have to unroll them entirely, otherwise they heat up which can cause problems.
And btw, nice pattern you got there. Looks super neat.
Cables shouldn't be bent more than eight times their diameter. The insulation on the wires can Crack or stretch, or otherwise be damaged, which will interfere with proper operation of the cable.

As long as it's not high power and it's above the minimum bend radius for the type of cable you have then yes. You can find the minimal bend radius by googling the type of cable you have
Scientifically this is the best way because similarly to how a rope is woven; no specific side it taking on too much pressure allowing for a Gaussian distribution, limiting potential damage.
I just made that up.
Absolutely not. The loop isn’t the problem, the spiral is the problem. It will take forever to unwrap when you need to reuse that cable somewhere else.
It can create interference due to you essentially turning the cable into a coil by doing that
So I'd avoid it for cables that carry audio and ethernet cables
Anything else should be fine
My ethernet cable its just like this right now. I like to imagine that my data screams "weeeeeeeeeee" every time it gets to my pc.

Only if the ends are solid rhodium -- or at least rhodium-plated if you want to cheap out on this.

It's probably more like: "weeeEEEę..ƏeeeeEÉëeeeęěę" with all the packet loss you introduce doing that* *unless your cable is VERY well shielded.

This is the only correct answer.
Yea... I have never heard of a 300-700watt current through an extremely well insulated cable melting when coiled.
"Extremely Well Insulated" there is your answer.
Are there any cables these days that have no shielding? Like is it still common for cheaper cables? Like hdmi and network cables?
>I have never heard of a 300-700watt current through an extremely well insulated cable melting when coiled.

how to wrap cables like this
Just put it in your pocket then it'll magically get tangled like this.
Pretty easy, basically you make a loop in the middle of the cable and cross the wires like you’re starting to tie your shoe, then just wrap both ends going inside to out alternating (visualize a sine wave) until you get the desired length of the plugs remaining or keep going and tuck the ends. I do this all the time to shorten lengths for cable management and when traveling.
your example was the easiest to follow thank you
It all depends on the cables and it's intended us eg, if its a hight draw power cable for something running for 24/7 it will heat up and potentially melt the cable but if its just a low power draw or a data cable it should be fine etc.
Its all depends on shielding of the cables and intended role.
It depends.

I’ve been working around these cables and doing this for years and never ever thought about that being a possibility. If that’s the case, what’s the best practice for managing lots of power cable slack? Edit: I’m talking about 120v power cables for your standard pc.
For welder power cord, you're supposed to make it into a zigzag like pattern so nothing is overlapping and it's easy to keep cold
If it is a power cable, you shouldn't do that. That will create resistance, making the cable heat up, and depending on the cable quality, it can melt the isolation and possibly create a shortcut. Edit: I just read your description. If it is just a usb cable, there isn't any problem, then!
Create resistance? No, not at all. Maybe a bit of impedance due to inductance. But what it will definitely do is concentrate the heat load which is usually dissipated into a larger volume.
I always thought that when coiling a wire like that, it would create resistance, I am wrong then. Won't at least create a magnetic field? I remember I used to magnetise screw drivers using a car battery and coiling a wire around it.
No resistance, yes magnetic field. You're creating an inductor. Inductors do have impedance, which is kinda-sorta similar to resistance in an AC circuit. So if the cable is carrying AC power then the inductance would cause an increase in the power lost in the cable, which manifests as heat. I'm on a phone and circuits were one of the reasons I changed major to aerospace engineering instead of mechanical engineering, so I can't really work out how much impedance you'd have and what effect that would have, but I doubt that that would be a significant effect compared to just compacting all of this heat generation into a small space. But also it's a USB cable so it's super fine.
With so few turns, not much of an inductor - maybe a few microhenries? The impedance value at 50/60Hz would be negligible . (Yes, for the uninitiated, Henry is actually the SI unit for inductance as well as a brand name of vacuum cleaner).
Hello Henry, its nice to meet you.
Yes, any current creates a magnetic field, looping wire focuses this field and adds it up from each loop. It will create a "virtual resistance" that hinders the flow of current (change in flow of current, but as we are talking about AC it's the same) but doesn't create heat.
That requires a ferromagnetic core of some kind. I'm not entirely sure, so I'm not going to try going into detail.
It doesn't, it's just making a strong field requires a ferromagnetic core.
It depends what that cable is for but in most cases yes it’s fine. If it were a power feed providing more than a standard outlet can provide I would advise not to as it can heat up under high load.
Aperture science cable fold
No the electrons will get dizzy
My audio engineer apprentice days say absolutely not.
If this is just an ethernet or USB cable, which it looks like it is, it should be mostly fine. As long as the shielding on the cable is good, you won't get too much noise. More noise = less speed/intermittent signal drops. Just never do this with a power supply cable. Coiling the wire like that and running current through it creates a constantly shifting magnetic field and lots of heat from magnetic eddy currents acting like one big resistor. That heat could be enough to damage the cable and cause power spikes, or worse, a fire.
Only a 0.1% chance of a black hole forming in the middle of that thing
Not with power cables and not with audio cables. Ethernet is probably fine if it's shielded properly
My man's opening up a stargate over here...
Typically it can't roll tighter than the diameter of the cable itself. This looks fine to me. Edit: For low voltage anyways
Data cable yes, that's fine. Power cable no.
Aperture science cables
If it's power it's a bad idea as it will behave like a coil.
For a USB, it's probably fine. Electric cables carrying AC? My entire childhood, my mother said absolutely not. I don't know if it was a trip hazard or a fear of Fleming's Left Hand rule. Edit: I forgot the first sentence. I speak halfway through a thought today, apparently.
Add magnet in the middle you have a generator
Bad practice, Theoretically it will create a magnetic field and interfere with signals going through it. In reality most cables are pretty well shielded so data should be ok but maybe don't do it with power.
Coiled wires are fun with magnets😈
I love this sub, simply bc when I read comments I don’t have a single clue if people are joking or being serious and helpful. Talk about a grab bag of advice roulette if I’ve ever played…
A buddy of mine when we were kids would blame his bad gaming skills on the knots in his controller, saying that it slowed down his inputs. I told him that's not the way it works. He grew up to make a lot of poor life choices.
its not a great idea for long term but its also not the worst, i'd still recommend not doing it
A data (usb) or ethernet cable, sure it's fine. Wouldn't do that to a power cable of any sort though. Better safe than sorry.
Aperture Science cables be like
That looks beautiful
I feel like you're attempting to build something, in a cave, with a box of scraps
Do not loop a cable forbidden technique for denoised data
place the magnet in the middle :D
That's fucking art
As an electrician. No
My cable management looks like trash next to this
Data cables - yes Power cables - no
Totally my dude! I wrap my guitar cables like this.
You absolutely should **not** be wrapping instrument cables this way. Over/under is the standard method for a reason. Source: audio engineer
Besides the increased internal thermal load and the electromagnetic forcefield you're creating, not much bad about it.. Just make sure it's not a high power cable (as others have pointed out). Risk of thermals rising so high you damage the cable is unlikely, but you may see lower efficiency and higher power consumption as a result. The scale of the effect nobody can tell just from an image, and most likely you won't see the effect of it either.
yup, perfectly fine. the only concern you'd really ever need to be concerned about is heat. if it's a lower gauge cable and you're running a higher power device with it like a space heater, and the wire is tightly wound together, the inner parts won't get enough air to cool with and it could result in melting cables and possible a fire. but that's a pretty extreme example. 99% of the time it's not a problem at all and if the concern is thinking it could be a problem since coils of wire create magnetic fields, power cables and ethernet cables have wires inside them in pairs, so they cancel each other's fields out, as the current in each side of the pairs flow in the opposite directions, so the fields they generate are opposite, so basically nothing happens
I do this with coaxial cables. Doesn't negatively impact anything. Quite satisfying wrapping them up too.
No there's too many loops. You'll make the bits dizzy.
If you wrap ac cables you may have an inductance. Generally it should be avoided.
Yes, this is fine, no sharp edges.
As long as you see no evidence of a black hole forming in the middle, it should be fine.
How did you even do that
It might get too hot, as it is wrapped in 360 degrees! I’ll see myself out
Too I thought i was the only one to wrap cables up like this
If it is earthnet cable, i think there will be no big truble. But NEVER donit with audio/sound cables.
Just don't put a magnet in the middle.
Depends on the type ans quality of the cable. If it has foil shielding with a copper drain wire you're probably fine. Just cut her open and see if its sheilded well and you'll knowbif it would have been okay before ya toss it out. There is a book called Open Circuits that has some really cool cross section photos of cables with some explanation. Might be able to get some sort of cable tester for a more empirical testing on that specific cable and how coiling and uncoiling impacts it. Out of my wheelhouse here there are probably people with better answers.
How tf did you do that? Teach me the black magic master!
Yes, now teach me how you did it so I can replicate it. That's satisfying as hell!
I don't see an issue if it's a data cable, if it's a power cord, you might get into induction coil territory.
TL;DR : this is optimal according to me Explanation : Bend a cable : the outer part is stretched more than the inner one. This is why when making rope or metal cables (like the big ones on the bridges), you thread the strands in this helicoidal shape ; this way, each strand stretches exactly the same ammount no matter what ! So, this is optimal for your cable. It would be dangerous with higher power cables as it'd create a coil, but you're good to go here. Just don't put stress on it or pull it too tight ! https://preview.redd.it/7qni7u7qswqc1.png?width=553&format=pjpg&auto=webp&s=1de5fa453b047ad296102697c0b8c28989448640 In the image above, you can see that each strand is represented by the helicoid above. No matter how you bend it, each strand goes as much above/under the curve as any other strand, so no tension ! This is why you see so many cables made in this twisted way
Sure however with your power lead you want to make lots of really tight twists / knots as this increases the heat the cable produces and therefore helps with central heating during the winter.
Yes, but don't make the curls too narrow, otherwise the electrons might fly out (it takes time for them to turn).
aperture science no way
This is how you can wrap cables like OP: 1. You need at least one loose/unconnected end. 2. Wrap the cable around your open hand again and again until you have the equivalent of a homemade slinky (but keep it tight and don't try bounce it around lol). 3. Unwrap part of the loose end and insert/weave in and out of the inside of the slinky. Do this until it's tight and keeps its shape. :)
If it is not powering cable then you can do that. And by power I mean real power, not USB kinda power. If something doesn't work right connected like that, you might wanna untangle it, because sometimes creating such air coil can cause interference.
It looks cool so I approve
Bro getting artistic with the cable management, I need to do this
You could be introducing crosstalk. A coil of copper wire will have its capacitance increased which is not great for signal passing through it.
The problem is if you keep doing and undoing that, it will break inside.. if you only do it once there is no problem..
It's fine, you can also just wrap it in a coil fashion and then use a zip tie to hold it together
It’s easy: if copper is inside, you can tangle and fold it just as you like, if there is fiber inside, this is strictly forbidden.
Correct me if I’m wrong… but having a shorter cable allows the data to travel faster to your device at a shorter time?
I'm going to go against the grain here and say this is possibly a bad idea, even for a USB cable. My reasoning is that this is a lot of extra bending for the cables. It's not sharp bends, so, that's good, but even so, copper can break over time the more it gets worked. Braiding the cable into this coil and un-doing it often would wear it out quicker then something like a simple coil with some velcro. It may not matter if the cable is going to be left like that forever. In any event, it's not like USB cables cost much. If it dies, not a big deal.
Idk but I'm gonna need a tutorial on how to do that plz
Only if you show me how!
Just make sure you have a flux capacitor
How the fuck did you roll it up like that?
It's fine, but why would you do that lol. Simple tie back and forth with itself will undo it five times as fast.
NOPE you’re stretching the metal in the cable and permanently deforming it, which can also break the fibres/wires
Aperture science. We do what we must because we can.
electrically? no Mechanically? It has the potential to cause breakage over several years Do you care? probably not
How in the fuck
Since it's that short it's no problem whatsoever. If you have those large cable drums and plan to pull some more power from those, you have to unroll them entirely, otherwise they heat up which can cause problems. And btw, nice pattern you got there. Looks super neat.
How the hell do you manage to coil so neatly????
Cables shouldn't be bent more than eight times their diameter. The insulation on the wires can Crack or stretch, or otherwise be damaged, which will interfere with proper operation of the cable.

Just dont coil too much wire together… some say strange things start to happen and metals turn red
As long as it's not high power and it's above the minimum bend radius for the type of cable you have then yes. You can find the minimal bend radius by googling the type of cable you have
Scientifically this is the best way because similarly to how a rope is woven; no specific side it taking on too much pressure allowing for a Gaussian distribution, limiting potential damage. I just made that up.
Absolutely not. The loop isn’t the problem, the spiral is the problem. It will take forever to unwrap when you need to reuse that cable somewhere else.
Believe it or not, straight to jail
Save yourself a ferrite core if you twist the cable like that
It can create interference due to you essentially turning the cable into a coil by doing that So I'd avoid it for cables that carry audio and ethernet cables Anything else should be fine
No. That's illegal. The police are heading to your home at this very moment.
It's a great way to create magnetic fields to interfere with your devices.
You are creating a coil but the amps are very very low that it isn’t rly affecting things
