Earlier quoted context omitted.

The narration is very nice. Any idea of what the data could be? He mentions that it's legal for him to store but illegal to sell abroad and ranges from "bad to very bad".

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

Creator here, thanks for posting. And feel free to ask me anything!

amazing project ! well done ! inspiring to see it this morning the youtube algo recommended it for me. I was thinking what would be a budget way of creating this ? maybe a $20 SDR instead of the hack rf , seems to be a waste of the hack rf to use it as a lamp :)) I think the way you did must have cost you over $1k. Thanks for the inspiration !

HackRF isn't a good SDR by any metric except for the date it came out.

Cool project. Here's some OT: where do people learn to make these videos? Fast paced but calm narration with chill music and sped up action mixed with regular speed. It's a matter of consuming a lot of this content until the form clicks, or you need to go to influ-school?

No influencer school, no video experience whatsoever actually I watched TONs of youtube videos growing up and I guess I took inspiration from what I liked in each: fast pace, always shows what you are talking about on screen (no talking head), include tiny projects in the main one, explain the science, use an intro to captivate and an outro to nail the point, use music to drive rythme I film and record audio with jus…

Man iphones have come a long way

Very cool, was there a conversion or look up table to convert db to gamma for more accurate human visualization?

I'm not sure what you mean

The db scale is logarithmic but doesn't match how our eyes sense light. So small changes in db may result in large visible light changes, or vise versa. Have you ever looked at a raw image, it doesn't look correct untill a gamma is applied, even though roughly the same information exists in both raw and gamma images. This is a similar concept. To do do this: db > linear > gamma This can be precomputed into a lookup table with the number of entries being the number of current steps, 8-bit 256 entries.

What would a better alternative be?
