Raspberry Pi 2 Doesn’t Like its Picture Taken, Shuts off as a Reaction to Flash
We often encounter weird bugs and issues in our devices. Over the years, we have gotten used to all this and nothing surprises us that easily.
With that said, I was really surprised when I read about a really unique problem encountered by users of Raspberry Pi 2. Here’s what happen: it turns out that Raspberry Pi 2 is “camera shy.” That means the mini system won’t react well to you taking pictures of it!
According to a number of users on a forum for Raspberry Pi owners, the system crashed and turned off as soon they took a picture of it up close. Hard to believe right? How can that happen? It’s all true as one of the users posted on Raspberry Pi Foundation’s message boards:
“My PI2 is camera-shy! Taking its picture with a flash causes an instant power-off! I’ve done it three times now and same thing happens each time.”
Later on, many shared the same story after trying it out. The problem was later acknowledged by JDB, who is an engineer at Raspberry Pi and is often seen roaming around the digital boundaries of Raspberry’s message boards.
“With a Canon Ixus 60 (handheld compact camera), its flash reliably locks up the Pi,” said JDB. “You need to be closer than about 50cm to make it happen, though.”
So what’s the actual issue here? It seems that the problem lies in a little U16 chip that is a part of the supply circuit.
Camera flash at the right frequency freezes the system. However, it only happens with cameras that use Xenon flash as LED flashes seem to have to have no effect.
Strangely, previous generations of Pi boards are all immune to what is being called the “Xenon death flash.” Covering the chip with a Blue Tack or similar means is being offered as temporary solution. If you wish to have a more permanent solution to this, stop taking pictures up close or put a cover over the whole thing.
This little problem doesn’t mean you should stop buying this system. It’s a really decent machine with more RAM, better processor and more USB ports compared to its predecessor.
It’s available for just $35 and you can even run Windows 10 on it. So if you plan on buying it, don’t let this weird flash problem change your mind.
