[arm-allstar] Overkill Controller Setup

[Mel Frerking]

David,

Let me ask a bonehead question that has probably been addressed on here before.  You mention "a robust power solution" and I am wondering if you are recommending something more along the lines of 1) more reliable power, 2) something along the lines of a mini-UPS, or 3) a way of powering down the pi gracefully during a power outage?

Thanks and I certainly appreciate all of the insight and problem solving that you provide here.

Merry Christmas, all.

Hi Mike,

Certainly, you can manually configure the HamVoIP installation to boot
from an SSD drive.  Personally, with the money for the SSD, I would spend
that money on a robust power solution instead.

I've run into an assortment of hams who are just convinced that SD cards
are unreliable---I've stopped trying to convince them otherwise.  My one
comment has been that if you're buying quality SD cards and continually
having failures, whatever is causing those failures will probably also
cause the SSD drive to fail, too.  Remember: if at all possible, just like
for any Linux system, perform a proper powerdown, if possible.

I've still had *NO* SD card failures at all, even on systems I very
heavily use, like my development boards and on hard to access repeaters.
Several of these repeaters are now reaching 2 years since the last RPi3
reboot!  I've got about 60 RPi4B boards now co-located in my "Pi Farm."
No SD card failures at all.  Absolutely perfect performance.

I'm using these DC-DC converters to provide the 5V power to the RPi3/RPi4
boards:   https://www.ebay.com/itm/223524573272

And, these SD cards:   https://www.amazon.com/gp/product/B07MR6K8PD


Note that these prices are about 50% higher now than last year...GRRRRR
At least they're in stock.


Merry Christmas!
