A friend of mine has an AC power to Ethernet adapter cable.
In unrelated news, he was once told that his employer would not replace the horribly out-of-date office printer until it was 100% unrepairably dead, and it mysteriously died a couple of weeks later.
Ah yes, IEEE 802.3HV.
When PoE just doesn’t cut it
Really hope it involved a baseball bat and a field.
Nah, visible damage is a no-no. For small items that “we don’t replace them as long as they work”, a few seconds in microwave does the trick.
For larger ones, you need to penetration test them against 220 volts.
Giver the 3 phase
Is friend a Texan named Jack?
Can I get that with USB-C or do I need another adaptor? Thanks!
Is this from USB to gardenhose?! So I can finally connect my old thinkpad to the projector?!
it’s a series of tubes (not a big truck)

In case you’re wondering, some broadcast equipment, such as the Axia Radius, uses Ethernet sockets for the connection of balanced and unbalanced audio.
This simplifies cabling, but you need adapters at the end of each cable to go back to RCA, TRS, XLR etc.
This looks so cursed
Some networking equipment has serial ports (RS-232) that use RJ45 connectors. 3.5mm TRS connectors are also commonly used for serial ports.
In my home studio I have a Behringer S16 digital snake which connects to my X32 in the control room with only a single CAT5 cable in between. So it’s literally sending 16 channels of audio with a single ethernet cable. Pretty cool!
How else did you think they got the dialup noises to play?
Dialup didn’t use ethernet.
Care to elaborate? I can’t find any information searching online.
No.
Ethernet is rj-45, dialup used 11/25
Thats wrong. This is how they got dial up to play

This could come in handy for my USB industrial smelting oven
This will be handy when I need to run my industrial machines from USB.
Useless, you can’t charge from USB-a!
(Seriously, it would be a fun project to stuff a USB powersupply in the 400v plug and a add a USB-c cable to mess with people at work… I’d do it but we only have 230v 3-phase outlets and that plug is probably too small.)
I think you can fit a fairly powerful GaN charger in that space.

No you can’t. That’s stereo. You can only hear the internet yell at you.
You’d need three lines for an output.
And it will be just as useful as without that adapter.
You could use it if you had another one with a female headphone jack. You could play your music to a speaker in another room if you have Ethernet in both rooms. Copper is copper.
I’ve done this. I’ve made speaker wire to ethernet adaptors to connect speakers in a different room through the walls to an amp. Feels and probably is so wrong.
It really depends how much power you put through the cable, ethernet is something like 0.2 mm2 per core. You’d definitely want to double up cores.
While, as you said, both wires will conduct electricity just fine, they will have different AC impedance.
I would guess this wouldn’t make much of a difference if you go Audio->Ethernet->Audio, since sound is at fairly low frequencies. But Ethernet->Audio->Ethernet might have problems with really high data rates, like GiB/s.
Hell, 10/100base-t only uses four wires so you could run internet through a 4-pole 3.5; though YMMV depending on the particular 3.5mm’s specs. I don’t know if drivers would be a problem, but perhaps a 4-pole 3.5 to USB would be handy.

If you get the stereo + mic plug, you get four coppers. That’s enough to carry standard 10baseT.
With 1000baseT1 you can even get 1000Mbps (full duplex). The challenge is to get that 600 MHz data rate over a cable between the two points. With proper insulation, 802.3cy can even get you 25Gbps over a single pair if your cable is of high enough quality.
So you’re saying all those gold plated, vibranium braided, ultra expensive hi-fi cables audiophiles buy can actually help carry good speeds over a useless adapter system?!
Not for anything following the cable spec on HDMI cables, but a proper coaxial cable between the 8P8C plug and the headphone jack should be able to carry the bandwidth necessary.
Better quality cables on analogue media do help, of course. They just don’t do anything on spec-compliant HDMI cables. Sadly, spec compliant cables are more difficult to find than yoh may imagine, and even the gold-plated, diamond-encrusted cables don’t necessarily follow the spec.
Fun fact: usb uart to audio jack is actually a thing: https://ae01.alicdn.com/kf/HTB1G43QaOnrK1RjSsziq6xptpXaN/win8-10-android-mac-pl2303hxd-usb-uart-ttl-to-2-5mm-audio-jack-serial-adatper-cable.jpg
Some older android phones used the audio jack double duty as a serial debug console, the nexus 5 for example.

Yes, it’s awesome!
I totally used an adapter like that. It did have a raspberry pi in the middle, though.
I mean, the PinePhone has a switch to change the audio jack from audio into some kind of data transfer protocol. I guess someone could make it work.
Audio jacks have been muxed as debug serial for ages.
I use 3.5 stereo as an rs232 connector all the time. A poe ethernet to serial would be a huge help to me.
I think you would need another connection (ie. a 3rd stripe, TRRS vs TRS cable) for data transfer. Although digital audio is all data anyways I guess and now I don’t even feel right but I’ve already typed it out.
Can I do dial-up over VoIP?
You joke, but it happens… I’ve had to deal with it supporting credit card processing. Once had a guy calling on a magic jack complaining that his credit card machine couldn’t connect. Once I found out he used the same magic jack for both, I had to explain that in the same way we could barely understand each other through the distortion, the credit card machine was having the same problem.
Finally, I can connect my Sinclair ZX Spectrum to Ethernet!
Only if you have the TRS to D-DVI converter, and those are super super rare.
i made a male version of this 4 times and then bought a ABC RJ45 switchbox for my work desk, so i could choose between computer audio and desk phone audio and cellphone audio through my work headphones… lets you bump your own music in between calls without dealing with pause buttons etc… worked great.
A manual switch?
Does it care that it isn’t the sort of signal it is expecting? I guess since it’s a physical switch it may not care.
yes its a manual switch, the analog audio signal doesn’t know or care. those boxes have no electronics.
some older people enjoy having a oversized knob to play with.
ha! beat my Bluetooth network cable!
This is so you can record the dial-up sounds.
