Raspberry Pi 2 Review
The microcomputer designed to get kids interested in coding powers down when hit with high-intensity, long-wave flashes from cameras.
Raspberry Pi 2, the latest edition of the cheap computer designed to get kids into coding, has a slight defect that causes it to blink every time it’s hit with a high-intensity camera flash.
Some Raspberry Pi 2 owners discovered over the weekend that when they photographed the device with a flash, it would turn off. Since then, Raspberry Pi Foundation employees have been analyzing the device to see what causes the issue, and according to a company spokeswoman, it happens only under very specific conditions.

“Flashes of high-intensity, long-wave light — so laser pointers or xenon flashes in cameras — cause the device that is responsible for regulating the processor core power (it’s the chip marked U16 in the silkscreening on your Pi 2, between the USB power supply and the HDMI port — you can recognise it because it’s a bit shinier than the components around it) to get confused and make the core voltage drop,” Raspberry Pi Foundation spokeswoman Liz Upton wrote in a blog post on Monday. “Importantly, it’s ONLY really high-intensity bursts like xenon flashes and laser pointers that will cause the issue. Other bright lights — even camera flashes using other technologies — won’t set it off.”
Raspberry Pi 2 launched earlier this month for $35. Like its predecessor, the microcomputer is a barebones device designed for people — especially kids — who want to learn coding. Since its launch in 2012, the Raspberry Pi has proven extremely popular with DIYers and a wide range of technologies have come out of it, including everything from gaming devices to media centers and wireless controllers for speakers. Millions of units have been sold since inception.
