If you had an old HTC windows ce 6.0 it might work.

Pretty sure those were mini USB.

wall outlet › USB-A › Micro USB › USB-C › THC

You convert electricity into tetrahydrocannabinol, the principal psychoactive constituent of cannabis?

Neat!

Show threadChaoticNeutralCzechOct 9
MicroUSB does it with MHL, which is the less addictive one

You get high from a wall outlet? Cool!

You can convert USB-A directly into THC!? Since when!? I’m about to get so fucking high, I’ve got a drawer full of those old cables.

What did dude think was coming out of the VGA port? Tiny photographs? It’s all electricity through wires, of course it’ll send some electricity into a phone
Show threadTimeNaanOct 9
Yeah but is the voltage correct? It should be 5V to charge a phone over USB, is that part of the VGA spec?
Show threadzurohkiOct 9
With USB power delivery, you can get 9V, 12V or higher over USB. Usually the device requests higher voltage from a PD charger, but it’s not impossible for a modern device to be able to cope with just having 12V shoved into it.
Show threadFishFaceOct 9
The USB device would have been made wrong if it just shoved 12V down the power lines without negotiating it.
Show threadzurohkiOct 11

That’s probably only true for USB power supplies - a USB adapter isn’t set up to do anything with voltage and probably just passes the positive and negative pins through.

The VGA adapter feeding power back through USB in the first place, yeah, that’s not supposed to happen.

Show threadFishFaceOct 11
Put it this way, either the standard on the other end of the adapter specifies 5V, or the adapter doesn’t just pass it through, or the adapter is broken!
Show thread9point6Oct 9

Yeah I don’t think there’s a 5V pin for VGA.

I think if we had the scenario where we had a higher voltage than needed, we could have a toasty voltage regulator making something happen, but going the other way would need boost circuitry unlikely to exist in these parts, in my understanding

Show threadbrown567Oct 9
There is! It’s pin #9
Show thread9point6Oct 9
Ah my memory failed me then! Thanks for the correction, I guess this is technically possible then!
Show threadAniviaOct 9
Doesn’t matter. The VGA to HDMI adapter is active, not passive, so it matters if HDMI has a 5v rail, not VGA
Show threadFluffy_RuffsOct 9
If, hypothetically, VGA didn’t have a 5v rail then how would power get from the monitor to the HDMI adapter. It would absolutely have to be a part of the spec.
Show threadAniviaOct 9

It doesn’t need to be 5v. An active adapter can have a buck converter.

In reality active HDMI adapters get powered by the HDMI device though, not the VGA monitor, so it’s a moot point anyways

Show threadknight_alvaOct 9
If the vga/hdmi adapter is active then this abomination could actually pass display information provided you had a micro-usb device that supported display out over usb (idk if there is such a thing and if so it probably doesn’t work all that well but still)
Show threadSundrayOct 9
It’s sending out the pixels, silly! A stream of little pixels in neat little rows.
Show threadSkyezOpenOct 9
I don’t know shit about cables but it’s plugged into a monitor. My intuition is that a monitor shouldn’t be pushing power out through a video input port.
Show threadzurohkiOct 9
Signals aren’t magic, they consist of electrical power. You can get at least a little bit of power from anything that isn’t an optical port.
Show threadfrobeniusnormOct 9
Show threadFerkOct 9
Technically, even an optical port delivers power. Visible light is just a particular form of electrical power that transmits a bit differently (you might need a different detector to make use of the energy from a beam of light), but it also has an intensity, voltage and resistance in the medium of propagation.
Show threadFishFaceOct 9
You cannot charge a phone off “a little bit of power”.
Show threadpivot_rootOct 9
DisplayPort has a +3.3V 500mA pin specifically for pushing power. In theory, great for powering an active adapter. In practice, has killed motherboards because Dell can’t design a computer for shit.

Show threadboonhetOct 9
Friendly reminder that if you use a Dell charger on a HP, nothing happens but vice versa, you damage the motherboard. It kills a chip used for charging. Dell used the same size barrel jack, but they wired it differently from everyone.
Show threadVindictiveJudgeOct 9
The monitor has to send some data to the computer to tell it what screen resolutions it accepts. VGA, HDMI, and DisplayPort will all do that for sure. Less certain about component, composite, and S-Video.
Show threadunknownuserunknownlocationOct 9
Of course electricity comes out of a VGA port, but it's only a signal, I wouldn't assume that it's anywhere near enough to charge a phone.
Show threadbrown567Oct 9
Pin #9 of the VGA spec is 5v, though it seems unusual that a monitor would provide power on that pin
Show threadpotoooooooo ✅️Oct 9
Thank you, I call bullshit.
Show threadTheOakTreeOct 9

Maybe somewhere in the chain, the 5V from pin 9 is being converted to 5V shared across power and the video signal. So even if this chain worked in carrying a video signal it could be very weak or distorted.

Purely a guess though.

The VGA port on a monitor is an input.

I used VGA up until maybe 2012, 2013. Even longer at my job.

Thats cute. There are so, so many machines that have vga still in my field.

Basically every hmi panel in existence use vga still. And password-less vnc.

Show threadboonhetOct 9
What did you use then? I remember cheap monitors in the early 00s ONLY having VGA. By the time I’d moved on, HDMI was so ubiquitous, I skipped DVI instead.
Show threadLastYearsIrritantOct 9

If you were rich enough, could have only used displays with RGB-BNC.

Or maybe they’re kinda crazy and used Component video with a TV screen. (Or composite…)

Or maybe they’re just not that old.

Show threadClay_pidginOct 9

I’ve never even heard of video over BNC, and my searches turn up SCART adapters, so I’m guessing it was a British thing?

I think we were talking about computer monitors, not televisions.

Show threadLastYearsIrritantOct 9

BNC connections were used on professional level video equipment, if you were rich enough, you could get an extremely high quality computer monitor and video card that used those.

Older computers, especially early home computers sometimes just had composite connectors to a TV. Older computer monitors often had a composite input, but SCART was also an option.

Higher end computer monitors sometimes had similar inputs to early HDTVs, there’s a lot of crossover.

The only time I’ve encountered VGA was my first year as an intern when my office had given me a flat screen monitor that frequently gave me migraines. Thing had to be older than me. That was 7 years ago.

If I encountered it before that, I wasn’t aware of it because I was a child and wasn’t responsible for plugging in the monitors I was using.

I remember when CGA and EGA were normal and then this fancy new VGA came out but only on fancy high end computers and monitors.

VGA was still very common around 20 years ago.

The micro is probably charge only, no data. So no signal.
