Such bursts of light affect the device that regulates the processor core power. The Foundation also found that the fainting spells happen only under very specific circumstances: namely, given flashes of high-intensity, long-wave light, which include laser pointers and xenon flashes in cameras. That doesn’t make it a great idea to take lots of photos of your Pi or to interrogate it with laser pointers, though, given that the subsequent crashing or rebooting could corrupt an SD card, she said. Here’s a screenshot that shows what happens when the Pi encounters intense bursts of certain types of light:įortunately, the Foundation found that the Pi won’t suffer any permanent effects from being flashed, Upton said. The Raspberry Pi Foundation – founded in 2009 to promote the study of basic computer science in schools – took a look. Onion found that when he snapped a photo of the computer with a flash, it causes an instant power-down. Peter Onion, a veteran of Raspberry Pi forums, on Saturday posted about his discovery that the Raspberry Pi 2 is camera shy. If you own a Raspberry Pi 2, congratulations: you’re also the proud owner of an elegant demonstration of the photoelectric effect! Not only is the bug harmless, it’s also packing a bonus lesson about Albert Einstein’s discovery that when light hits a component, it generates a charge, Upton says: It’s the most adorable bug ever, Raspberry Pi Foundation Head of Communications Liz Upton said when she posted about the finding on Monday. And if you’re still watching the log file on the “master” you see the magic start to happen.Owners of the recently released Raspberry Pi 2 – the itty bitty, budget computer – have found that the credit-card-sized systems reboot when users snap a flash photo of the units.We called our devices TOP and BOTTOM and gave them ID’s of 1 and 2.So to join our HA master on eth3 all we needed to do was:.To enable Cluster mode, please specify these parameters: To enable HA mode, please specify these parameters: To enable Zeroconf mode, please specify these parameters: To disable Zeroconf/HA/Cluster mode, please use: The key command here to setup HA is sethacfg.You should then end up logged in at the # prompt.Then just enter the New password you’d like to use. For the current password you can put anything, we left it blank. You’ll be asked to change the password. If you haven’t got a fresh box then use the LCD panel to reset it to Factory Defaults. Do not put the USB stick into it, we don’t want any config at all.
