Around $200 delivered to france

I'm not sure what you mean

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

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 just my phone

I used JLCPCB for the pcb cause they integrate well with the pcb design software i use (kicad or easypcb)

And I used pcbway for the sheet metal fabrication

Honestly they are both great and similarly priced

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

To be honest, all of the hardware and software is really poorly documented. But I guess i coudl still publish it as is

I wanted to take it war driving around paris and the countryside, maybe i'll make a separate short video for that

CS background, but I've always been a "bricoleur" on the side

Yes, in the parisian apt. where I filmed the RF landscape is wild

But tuning in to the specific wifi channel you router use you could even use this piece as a signal strenght plotter!

I had to dig deeep in my soundcloud to find it!

Yes each LED channel has an inductor. I needed this because I wanted the LED to be constant current driven, to reduce flicker and improve their longevity

(and they cost like 5ct each)
