How to fix annoying blinking flashlights #ReverseEngineering
It seems like every flashlight bought these days has several modes: one you want (light), and a bunch of useless blinking ones. The electronupdate blog digs into the guts of these units to disable the annoying flashing feature.
Amazon sells a nice box of flashlights for a pretty good price. Even better they are quite well built with a solid metal body. The only problem is that the don’t just turn on. Each press of the power button brings a new mode. One mode is really annoying: a 2.2 Hz blink.
Moving one wire bypasses the chip making the irritating blink. See the video below and the blog for details and die shots of the blink chip.
