Really cool. If anyone is interested in learning a bit more about the theoretical side of phased array antennas, Marshall Bruner’s channel has some fantastic videos that discuss the math with some great visualisations: https://www.youtube.com/watch?v=jSDLfcNhThw
I haven’t seen a similar video on wifi, only a single attenna version from thought emporium so super cool to see the same sort of tech make it to wifi from smaller labs: https://youtu.be/zijQUOHOshY?si=1fixjPlHQRLB-oyM

The implementation is really clever. They get timing of all the Wi-Fi chips so precisely aligned, because they run them all from the same oscillator.
And because these are real Wi-Fi chips, not merely 2.4Ghz antennas, they can look for a specific network. Brilliant.
Reminds me of the the video on acoustic cameras from steve mould (https://youtu.be/QtMTvsi-4Hw?si=oFeOl-JZNMbPPTjW) or ben jordan (https://youtu.be/c5ynZ3lMQJc?si=Wpu08PTyF2wSyihI). Great fun and a lot easier to implement for a hobbyist due to the lower frequencies.
