  I admit it's a nice experiment, but I guess the title should be "detecting iPhone Lidar". Both the 60Hz frequency and 940nm wavelength are fairly specific. There's a whole world of different wavelengths (1550nm is fairly common) and frequencies (up to 1MHz isn't particularly exceptional). There's been a whole thread on the topic here: https://news.ycombinator.com/item?id=46110395 https://news.ycombinator.com/item?id=46110395

    Agreed, I immediately thought of vehicles, but this is cool too.

    Right, I wonder if they considered a pulse-detector with a dichroic filter and a 555?

  If you are sensitive to flashing - do not try to open this link. It is impossible to read because of videos of flashing lights.

    Makes me wonder about how safe lidar is for humam and animal eyeballs?
    • garbagewoman 11mo ago
      The videos are of invisible wavelengths of light transformed into visible light. Why does that make you ponder the safety of the infrared light?

      I have some very bad news for you about the kinds of light emitted by the sun and also your oven
