Hi all this is my setup -
IQ audio Digi-amp+
Latest volumio installed
Safe shutdown using pushbutton and led lamp ( also startup on same button)
The whole thing has been working perfectly for 2 years. I recently moved house to a rural location and find that we get frequent but very brief - a couple of seconds - of power outage. Each time it happens My SD card becomes corrupt and I have to re-write it.
I know that a fair bit has been discussed on this forum about UPS devices etc, but as far as I can tell, this has been all about backup for the 5.5volt power input for the Pi. Because my Pi is fed via the 18volt Digiamp + I need to find a way of getting up to around 5 seconds of backup supply at 18.5 volts and then a way of auto shutting down safely. I already have push button startup and safe shutdown installed. Could something be done utilising this somehow?
I really do not want to go to the expense of purchasing a mains voltage UPS as these are very expensive and it really is only my music player that I want to protect.
