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
