The New Hotness

  • Walkway Over the Hudson: Camera LEDs

    Under the plausible assumption the security / surveillance cameras along the Walkway Over the Hudson aren’t the cheapest junk available from a randomly named Amazon seller, this came as a surprise during a recent Walkway At Night stroll:

    The IR LEDs emit just enough red light to be dimly visible to the human eye, but appear much brighter to a silicon detector. I think the long gap at the bottom right is a sensor of some sort, so the array of 18 LEDs has two deaders, one near death, and six more fading away.

    The necklace lights on the Mid-Hudson Bridge are once again in good repair:

    They were showing fixed white light, rather than a moving color display, but it’s still a nice effect.
