Smartphone LED detects hidden cameras with an ESP32-S3

It does seem like its way too easy to put off publishing until it's "properly" done and then it never happens.

If this worked with IR, and so non visible, it might be worth noting that the major change in battles over the last decade seems to have a lot of progress much faster. Can't a thermal camera can do this? It should be able to do this with Frigate as well. If we're going to expend time and effort on finding new and exciting ways to destroy other members of our species, it might be even more useful. Great idea though.
