#102Creator here, thanks for posting. And feel free to ask me anything!
I actually got your video recommended by Youtube earlier today!
Glad my YT algorithm is on point.
But would it be possible to add an RSS feed to your blog please? (https://rootkid.me/works) That way I won't miss any of your future posts.

Nice art and a good way of story telling. Thanks for your work!

It's in teh description: "launching a fully functional darknet marketplace ( http://spectretjag3wni6fzt445qwgokqlxnfz7fxkicj5efxjywlinibm... ) that offers a trove of illegal data for sale across borders"
> offers a trove of illegal data for sale I'm precisely asking for speculation on what this data could be, which is the goal of the artist as stated in his video
Ah sorry, misunderstood. Probably credit cards etc

The $5 nrf52840 should be sufficient, it can scan 114 channels (from 2400-2514 MHz) several times per second, measuring the approximate RSSI.
You could not use that as an SDR to make a waterfall which is required in this case
You do not need a full SDR to make a waterfall. The nrf52840 can function as a coarse spectrum analyzer, because it lets you tune to any frequency within its range, and then measure the approximate received signal strength over a period of time[0]. I have tested this myself, and it works pretty well. The only downside compared to an SDR is that it can only listen to one frequency at a time, so it will sometimes miss short signals.

#106I often would love a camera similar to acoustic cameras / night vision cameras, but for RF. Like portable synthetic aperture radar.

I know it can switch frequencies, but I predict it wouldn’t make a very pleasing visualization if the updates are slow, but maybe you are right it would look fine for this implementation which is already far off from a waterfall

#108Aaa, I misread the title and thought that it was powered by the radio waves, regardless still very cool!

I'm personally especially interested in 'Latent Reflection'. I've tried to make something similar never got to a point where I was happy with the output the AI model gave me.
Lots of tuning to get the model to not immediatly spiral into nonsense. But small models are getting better by the minute, maybe i'll revisit it with a better model and share all the code
That'd be really appreciated. For me it just kept repeating the same phrase or just started reflecting on the prompt itself for a sentence or two after which it started spouting random nonsense like a pasta recipe.
