Sorry OP, this thread is about actual technology and not boomer conspiracy theories or jews so it doesn't really belong here.

After some research, I found Arc's mov instruction doesn't have memory access (similar to SPARC), and now the main problem I have is I don't know how to distinguish DMA IO and RAM addresses. The dongle I'm trying to modify is a DTV receiver, to emulate software defined radio functionality on another chip than the traditional RTL one, and the main thing I'm trying to find is how to send data through the USB port for further debugging.

Now you have me thinking OP

Cars/Construction Equipment an be controled remotely and tuned

Old satellite dishes into radio telescopes or just track and pirate whatever satellite frequency you want

Old network cards into scanners and jammers

You could probably turn a household microwave into a jammer or https://mad-science.wonderhowto.com/how-to/turn-microwave-oven-transformer-into-high-amperage-metal-melter-0140772/

>s1mp3 can run arbitrary code on chinese mp3 players

could someone use that to make very cheap bomb detonators?

would a modern, 21th century Ted use that?

Microwave ovens supposedly were ran with the door open pointing to the sky as radar decoys (bait for HARM missiles basically) during the Yugoslav war. How effective that was is unclear. It might work as a wifi jammer, but you'd have to check the frequency.

If we're including just any hacking (and not just firmware) then there are more examples. A lot of cheap SDRs are repurposed chips that were designed for specialized consumer purposes.

Parallel, serial ports and sound cards are used for different IO needs. Hard drives have strong magnets in them. If you break a little chunk and cover it in glue, put it in your ear and place a magnetic loop antenna around your neck you now have an invisible earpiece that probably rivals what government spies had until the 70s. Inkjet printers can use almost any liquid as ink. Laser printers can be used to make circuit boards (inkjets are less effective but I've heard they might work too).

Spotted the fed.

Oh, and forgot to say that besides the magnetron you can also get a pretty large transformer and some high voltage diodes and capacitors, which could be used as a HV power supply or for some other purposes (like turning the transformer into a spot welding machine). They're pretty cool devices. It'll be even more interesting if solid-state ovens ever become commonplace (they would have yuge power transistors going into the GHz range). I doubt (((they))) will ever let that happen though, can't have any random goy blasting thousands of watts of microwaves at arbitrary frequencies. Could probably be used to jam satellites tbh.

Cheap CSR8510 dongles can be modified to run in USB HID mode.

There's a premade tool for that, and there's also CSR ROM Config tool which can configure CSR BT audio chips too.

SammyGO which is a mod for Samsung TVs running linux, I think it's dead though.
