Since I’m quite new, maybe there had already been such inventions, but I’m kind of stunned. On the other hand I wish somebody reviewed this torch to see whether it’s useful for anything. Don’t have good memories with cameras attached to EDC items (like sunglasses or wrist watch), but I don’t want to prejudice.
Things like these have been around for a while. I remember first seeing them in bike lights. I guess there could be other applications that one might want to record e.g. caving or hunting…?
