Why Raspberry Pi 2 Crashes When You Turn on the Camera on It
The Raspberry Pi 2 is a great upgrade over previous models , but it also has a twist. It turns out that if you try to take a picture of the Pi with the flash, it will shut down . The Raspberry Pi folks explain exactly what’s going on.
Basically, when you blast the Pi with a xenon flash , the photoelectric effect takes over and knocks out some of the electrons. This causes the Pi to crash. This is all pretty complicated, but the good news is that it won’t hurt your Raspberry Pi 2 in the long run, and it’s a pretty isolated set of circumstances. Only a bright xenon camera flash or a laser pointer will power the Pi 2, other bright lights will not hurt. Of course, the easiest solution right now is to use a case or get a small drop of Sugru to cover the components. Head over to the Raspberry Pi website for all the scientific details.
