I'm loosing the overview: that's a raspberry jam!
You've got me beat by a factor of 2 (we've got half that many).
I have only had two RPi's die ever. One was an original 3B, the other was yesterday a 3B+, and the 3B+ came back with minimal damage.
I find the Zeroes are pretty unreliable.
Problems with the Pi0 series are often related to the extra adapters needed. Adding some HDMI boost or getting a direct miniHDMI-HDMI cable usually helps. Same with the micro USB adapter, eliminating that will often fix issues with hubs or other accessories.rin67630 wrote: ↑Tue Jul 09, 2019 5:11 pmI find the Zeroes are pretty unreliable.
I have a couple of them which refuse to put anything on HDMI, even after tweaking the config.txt. They run headless, so it is not critical.
I just start their SD card on another Pi.

Currently my favourite is the 3a+, easy to start with just a wireless keyboard/mouse, very robust, do not need additional frills.
The Zeroes W are really cheap, I start them with the SD card cloned from a 3a+. But it's good to have some in reserve.
I know, but for me it's so convenient to have a reference system with all my software and settings preloaded and up-to date, with VNC already cloud-configured.HawaiianPi wrote: ↑Tue Jul 09, 2019 6:29 pmYou don't need to configure a card on another Pi to run headless.
One thing I would ask there is what do you have the freq's set to on the zero's for you.rin67630 wrote: ↑Tue Jul 09, 2019 5:11 pmI find the Zeroes are pretty unreliable.

I have another Zero that works, but the processor gets really hot for no reason.
Plus two that died, don't know why.
One came with a broken ferrite coil, still works but drains noticeably more juice than normal.

I'm using 3A+'s as headless surveillance cameras. Its a nice cost saving over a 3B+. Smaller footprint too. And I have two of the original A+'s with sense hats on them. One runs 24/7 without a hitch.rin67630 wrote: ↑Tue Jul 09, 2019 5:11 pmI find the Zeroes are pretty unreliable.

That is because they are overclocked by default (my point). The factory settings on the RPi Zero are:
Code: Select all
arm_freq=900
gpu_freq=300
sdram_freq=400
over_voltage=4
You mean putting that in /boot/config.txt ?DavidS wrote: ↑Tue Jul 09, 2019 10:50 pmI would run a RPi zero at:Code: Select all
arm_freq=900 gpu_freq=300 sdram_freq=400 over_voltage=4
My thought is that that would improve the reliability. Clock them reasonably.rin67630 wrote: ↑Wed Jul 10, 2019 11:05 amYou mean putting that in /boot/config.txt ?DavidS wrote: ↑Tue Jul 09, 2019 10:50 pmI would run a RPi zero at:Code: Select all

Do I need to consider other things like timings to adapt?
I always found the Zeroes to be unreliable, maybe that would improve their reliability?
I don't need speed, my Zeroes run at 3% CPU.
