For many years now, we have used pixels, pixel controllers, and players. Our players have changed from full blown computers (desktop and laptop) to credit card computers (Raspberry Pi, Beagle Bones, etc.), the main part of the display has several (player/remote). The controllers have been subjected to power being turned on and off, but the players have always been on full time (always on) circuits. We do have one set of props that the controller is a RPi with a Falcon Pi Hat. This unit is subjected to the nightly power on/off cycle. We set the sequence times for this unit at 00:01 till 23:59 and load an onboard RASclock so that when power comes on, it automatically starts its sequence. When the power goes off, well - it shuts off.
I say all of this as we are now going to add 3 larger matrices that will be in an area that does not have full time power. They will be subjected to power on (usually 30 minutes before opening) and power off (usually 15 minutes after closing) along with the occasional "bounce" during opening or close. (People who can't handle the large breaker sometimes slip and it comes right back on.) In the early days there was the possibility of corrupting data cards, but to be honest we never experienced it with the PiHat on the RPi.
I've purchased 3 Kulp K8-B controllers (one for each stand-a-lone matrix) and am building enclosures and the matrix panels themselves. I am very concerned as to the K8-B and how it handles power on/power off cycles. ANY information would be helpful. In particular, I am looking for input if anyone else is using their K8-B in a power on/power off scenario and if there are any problems associated with this setup.
Thanks in advance.
