    QuadRF creator here. Happy to answer questions! We have a quick demo video as well: https://m.youtube.com/watch?v=QvniJk3uNyA Along with a deeper dive video: https://m.youtube.com/watch?v=zdJ9Tbm8ALg We didn't give Jeff great direction on camera alignment calibration or setting the radio gain but he seemed to mostly figure it out. We're improving the UI based on his suggestions (it's open source so you can customize it too) The RF augmented reality is just one of many applications of this brand new 4x4 MIMO software-defined radio built from the ground up. The AR uses a web app to stream RF points that your phone/laptop browser then live-merges with your local camera in the browser. I've been obsessed with low latency and high frame rate to make it a truly AR experience. More technical details at https://QuadRF.com/

    Funny, in the "imagine what governments are capable of" vein, I just read this[0] a few minutes ago before coming over to HN to find this post trending. [0] https://www.prnewswire.com/news-releases/the-future-takes-fl...

    One day I want to build something like this, except for sound. It would be great to get a heading and distance for where a sound is coming from. This could be both for small scale things (e.g. which part of this is squeaking?) or large scale (e.g. is that booming noise coming from the construction a few blocks away?)

    The visualizer reminds me of my thermal camera. I have heard claims of devices (mostly TVs) supposedly coming with secret 5G cell uplinks built in [never heard a specific model mentioned though]. If there were more variants covering more commonly-used RF bands, people could walk around and literally check for once. (incidentally i'm sure three letter agencies have had this sort of tech in their bug-detecting toolkit for a LONG time)

    Build this into smart glasses and it would be fascinating.

    I just kinda skimmed through it, so it detects drones in sky? Am I understanding this correctly? That might have some defense application considering what's going on in Eastern Europe right now.

    Would something like this work at much lower frequencies? Being able to see RF at 3-30MHz would be fantastic for hunting RFI in the amateur radio HF bands.
