I tend to believe something in the power supply circuitry is light sensitive (Xenon flash is pretty bright after all), EMP is unlikely.If you had the time and inclination you could mask off the whole board, flash, and my bet is it would still be running, then selectively un-mask a part at a time until you found the culprit :-) But, how many times would a bright flash be experienced in a repeater anyway?  ____________ Steven Donegan KK6IVC FCC General Class License SSCC/NORC Life Member, Car #86 www.sscc.us From: David McGough <kb4fxc@inttek.net> To: app_rpt-users@ohnosec.org Sent: Sunday, February 8, 2015 7:09 AM Subject: [App_rpt-users] Ras Pi 2 doesn't like xenon flashes??? Hi Everyone, I just saw this thread in another newsgroup. Basically, they're saying the Pi2 will hang/crash if subjected to a close xenon camera flash discharge! Weird! Can anyone confirm if this is true?  ...If they're sensitive to a flash, they might be sensitive to RF as well. Perhaps an EMP issue? Here is a link to the thread: http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=99042 Again, I have NOT personally confirmed this report, but am sitting here looking puzzled! 73, David KB4FXC _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users To unsubscribe from this list please visit http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users and scroll down to the bottom of the page.
