$5 USB to VGA adapter hacked to transmit radio

For low-res video?

1024×768×3Bpp×60fps ≈ 135MB/s
Try pushing that thru USB2, faggot.

Have you heard of compression?

The hardware for that is probably more expensive than a USB3 interface.

No really shut the fuck up

You're asking for a sixfold decrease in bandwidth, might as well just send encoded video straight to the monitor then. And this is assuming you aren't making it more expensive with display stream compression.
Can't believe I'm reading this on Zig Forums. What this guy said

USB2.0 to VGA exists. look up displaylink. It uses compression between the adaptor and a kernel module. They also reduce refreshrate, and there is no hardware accelleration to speak of. It's fine for text editing and web browsing but don't try to watch HD video on it. SD video is fine if you don't actually care about framerate (like if it's just a video of some prick talking to the camera). I used one on my x220 to get a third screen while docked but gave up on it due to instability when hotplugging (the driver never lets go of an interface, so every time it's reconnected it would just create a new one. After it regiserted more than 3 or 4 interfaces the chances of a a total crash/freeze got incresingly more likely). Also the compression takes a tole on your cpu, the more you have going on on the screen the more system load it creates. When i first got it working i tested it by starting glxgears on a native screen and then drug it over to the displaylink screen. The program didn't report a frame rate drop but the monitor couldn't have been displaying at more than 20hz with heavy tearing, and system load spiked to 8.0ish.

Unfamiliar with the tech. Can this reach AM-FM bands? Have pirate radio transmission points become much more affordable?

en.wikipedia.org/wiki/Analog_television#Receiving_signals
Yes they have just become more affordable. You better download that source code before it is shoahed though and upload it to IPFS for us.

Also something just occured to me, if it is possible to use every VGA device as a analogue modem, doesn't that mean every single device with a VGA port is a fucking botnet? As you could just use another VGA adapter with high enough power output directed at the frequency the VGA device is communcating at and simply send data/botnet through said receiver? Like for example if you are running windows sending the data for a function call in the memory range of the VGA device to say open a internet port or some shit like that. Literally a fucking botnet.

And if you can send data from VGA, couldn't you make a virus that hops air gaps using VGA and spread via the internet? It would be easy to make a function call that is consistent across windows/mac for such a thing. Maybe not so much linux or *BSD's though. Granted if it spread from VGA, not every VGA device is going to have a high enough power output to hop air gaps. Nor is every VGA device going to have the same memory adress to communicate with it like a radio. So it would take some work to botnet it like that. I think linux has a header file dedicated to memory/PCI adressess of VGA devices though. So that would save some work.

And if you can botnet the VGA adapter recieving waves on RF, what else can you botnet? Is there a way to avoid botnets via the VGA device made into a modem? I realise if your software is bug free HAHAHAHAHAHA that you don't have to worry about this. So linux and *BSD's might have a harder time becoming botnet until a bug is found in the DRM subsystem for linux and the equivalent for BSD. Windows and mac are screwed as usual, especially windows computers which are air gapped as they would easily fall to such a thing. How do you stop this madness?

So HDMI supports DVI and HDMI is based off of the CEA-861 standard.
en.wikipedia.org/wiki/CEA-861
So theoretically a HDMI outputting device should support these frequencies, and by extension could be used to transmit radio waves also. Granted it would be very ineffeicient without a antenna of some sort. But that is what a HDMI cable could be used for if the shielding/plastic were removed from the cable. Someone correct me here but wouldn't this mean that almost all video cards could be used a a wireless modem which is botnet with enough power?

Get a teletype and use ed, silly kid. Ed is the default text editor for a reason.

That's not a real answer. Some of us are forced to use shitty hardware for work. How do you mitigate this VGA crap if your work is supposed to be secure and you are forced by your employers to use VGA? Sure you could tell your employer its not secure and don't expect it to be secure, you could also get fired.

Oh to top that off, how exactly am I supposed to hook up a modern computer to a teletype after I have removed the VGA card(s) and set it up to use ed as input via teletype in the kernel? How is one even supposed to do this on windows? What about GUI programs? etc etc

Tough noogies! If you don't like teletype, you can just use front-panel LEDs.

Actually that would be more reasonable to obtain or make then a teletype. But that doesn't solve the VGA/DVI and possible HDMI botnet problem. How to get display devices that can display 3d video's and not lag like hell and not be botnet?

Plug in a Hercules card and use aalib.

Good. VGA should be banned too. Only HDCP compliant connections such as HDMI and DP should be legal. VGA is only useful for CRT anyway which will soon be outlawed for excessive radiation, harmful substances, eye strain, high carbon footprint (Japan saved 3 nuclear power plants of energy per year after phasing out CRT), etc. Seriously allowing citizens to transmit non-compliant radio is quite a problem. It can degrade quality of consumer technology like cellphones, ATSC, and also block emergency broadcasts, 911 calls, and interfere with the authority's communications. There are only a few people who are actually interested in radio transmission and they can get a permit from the government and go to an isolated area if needed.

...

Liar. You know nothing.

It does exist and it's utter shit. Why would you want a shit adapter when you can have a good one with a properly fast interface?

Only as a transmitter. It can't receive signals, and it will need an amplifier plus a good antenna to transmit at usable power levels.

...

From the article, the only reason this works well is because they can completely disable the horizontal and vertical sync on this chip.

If the pipe can send signals, in the fourth VGA pin reserved since E-DDC, it could recieve them also over a serial connection. But yea it would need a antenna and possibly an amp depending on the graphics card in use.

Retarded you seem to be.

why am I not surprised
>>>/gaschamber/

what is a joke

They could also turn off other pins to use them for serial data transmission. Or instead of turning them off putting enough power into the radio wave entering the wire to overpower it and force it back into the computer where you can then transmit data over your noise/energy excess you pumped into the pin.

Only the first one.
shitposting is life

Nothing new. The wire does not contain any ferrite cores so it's bound to broadcast and leak analog signals for free assuming the other side have some sort of "specialist equipment".
I'm guessing they had put some kind of wifi-like hardware to ensure the transmission of botnet though you don't need it thanks to the insecure little thing called wires.

That's not a hard part considering most VGA DVI HDMI cables no longer contain ferrite cores due to Obama's FCC Law while those who still have that dangling "magnet" thingy actually don't have anything inside!
USB doesn't evade this problem. It's just the same concept and as to why USB3 doesn't run at maximum speed when near interferrence (wlan cards, usb wifi, phones modems and routers).
I'd humbly suggest you people to cut off the wires of those keyboards and mouse of yours then replace it with cables with built-in ferrite cores or buy the clippable ones if that's too much of a job. By using such, you'll get better data and power transmission (which is why micro-B usb for camera and the old PSP used to have these)

Dors only VGA have this problem? If not, how do I check to see if my cables have iron cores?

They're the big lumps you see on many cables, pic related.

Fiber optic cable isn't susceptible to radio interference. Every other type of cable is.

They can be pretty important. A nice thicc well-shielded VGA cable with ferrite rings vs shitty thin poorly shielded one without the rings can make a world of difference. A VGA signal that isn't deteriorated by interference between the graphics card output and screen input isn't much worse from digital.

There's an article on hackernews about companies being afraid of outsourcing manufacturing because with components getting so small they can bury parts the company didn't order and effectively spy, control, or just sabotage the designer of the electronics

yes but how does this help me get moar free pr0n?

It works quite well.
Only the signal is really weak.
Anyone here has any idea how to boost it?

cannibalize a old radio for the antenna
telescope is preferred so you can tune the length to match the frequency

is your VGA monitor connected to a USB to VGA adapter? No? Don't worry then.

This is going from proof of concept to l33t haxor tier very quickly. Don't go botnet k?

Yeah that's pretty self-explanatory but where to solder it on the PCB.
I'm pretty sure the signal is coming from the fl2k itself.
I've no tools to solder SMD

Please don't judge me from my font choice
Terminus looks really good on CRT screens

An inline amplifier is what you need, my dude. Be sure to move around a lot so glow in the darks can't track you.

Ehh, that's not quite the issue. The problem is RF that can be captured from long distances ( approx. 100's of yards ).

Every computer is vulnerable to threats from unseeming vectors. The best solution for security is two-fold: establish a proper Faraday cage and use either a generator or battery/inverter system to power it all.

Danke schön user!
Sorry for my badly formulated question.
But is exactly the thing I was looking for.

lol, you're going to need a lot more than an amp.
But don't let that stop you from dropping dosh on one. It'll be funny hearing you blew out its finals the first time you used it.

"huur what is TEMPEST?"

wait, wasn't there something recent about hackers wirelessly getting into computers through USBs or something?

I don't understand. What are they doing with these shitty cables?

How much RF do you think a teletype generates? So long as your computer case and cables are shielded, you're pretty hard to spy on unless they get right up in your face.

You mean this?

I've used it before :^)

pretty sure the signal come from one of the exit pins.
