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…

Thanks! That kind of makes sense. It's always interesting to me when I see patterns that make videos work well, and I usually have a lot of questions about the production.

Another question that I hope is not disrespectful: does PCBWay and JLCPCB pay for brand placement during the video or was it just a tribute from your side?

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 is defo overkill for this. I got it cause my initial plan was to cover the whole spectrum

You could probably do it with a cheaper SDR, but it would be slower

Total budget for this is around $1k

FANTASTIC!! I was just thinking about this the other day, and wondering about directionality... For example, if you had a camera facing a space, and the receiving antenna was within that space... and you were able to (somehow?) from the antennas perspective, see the "direction" the frequency was coming from.. And then map the different specific frequencies within the desired bandwidth to colors... and of course inten…

Yes it has been done: https://youtu.be/sXwDrcd1t-E?si=V75bEPMT8qGbo1wG

your link has the "si=" tracking parameter in it

The $5 nrf52840 should be sufficient, it can scan 114 channels (from 2400-2514 MHz) several times per second, measuring the approximate RSSI.
