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 !

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

  • 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

  • IIRC, a regular SDR dongle will not be able to process the full bandwidth of GHZ range.

How much did that sheet metal frame cost you from PCBWay? Thanks for sharing.

Do you have a list you would be willing to share of trusted manufacturers & suppliers that you reference for different products or materials?

  • 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

Love your channel! Do you have any plans to eventually open source your projects? (Both in terms of hardware and software)

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

  • 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
