It's not reading the contents of RAM via EM emanations, it's using the EM emanations caused by certain memory access patterns as a side channel to exfiltrate data. Of course, that data could be anything, including whatever is in RAM, but the point is that you need to be running the code that generates the necessary memory access patterns to transmit the bits of data. This is not like TEMPEST where you can reconstruct a video display just using the emanations.

Is there something significant about this release, or are we just going to have a post every time every piece of software releases a new version?
If it was plausible this would be bigger news. There's a claim like this every couple of months and none have held up to scrutiny so far.

This is an interesting article and yet you've chosen to quote the most speculative unscientific part of it from the final paragraph.
"Have you tried going outside" is not a scientific cure for depression.

- Does your phone automatically join open wifi networks?
- Do you have worse cell signal than usual in this store?
You can see the planned specs for the two different models on their indiegogo page: https://www.indiegogo.com/projects/emudeck-machines-retro-emulation-console-pc#/
I'm guessing they have a pre-selected all-in-one board (designed for mobile devices) and they're just designing a chassis around it. There's still a lot that could go wrong, but it's a bit more achievable than actually designing, testing and assembling your own board.
You need to find a schematic for your car's electronics in order to get a proper solution for what you're trying to do. I would be particularly cautious about connecting a relay coil to some unknown wiring. The back e.m.f. from a discharging relay coil could easily fry a microcontroller if it happens to be connected to one.
So that would make it 1.4m in the last two weeks which makes a big difference.
It would have been nice for the article to actually discuss these specifics. I'm not sure what we're supposed to take away from it.
Can't wait to read about it telling someone to put glue on pizza.
