Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group :
FlashAir WiFi enabled SD cards
Two power solutions I like myself are:
The combination of these allows for really flexible production and testing environments.

I want to use btrfs as filesystem on a Raspberry Pi with opensuse Tumbleweed.
It is hard to find out how, so here are a few links that should help me from “opensuse” “tumbleweed” “btrfs” “raspberry” pi :

WayBack ] GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi : hybrid computer of a Raspberry Pi inside an Apple II (either ][, or ][+, or //e) so the Apple II can be a front-end to the Raspberry Pi which then can run an Apple IIGS emulator, talk to the Apple II storage hardware and much more.
It can run [WayBack ] RASPPLE II: A2CLOUD, A2SERVER, Apple II Pi for Raspberry Pi

It looks like OpenSuSE has stopped supporting Raspberry Pi 1, so the best likely is to recycle it into a Pi-Hole as basically it’s been dead since mid 2017: [WayBack ] Raspberry Pi 1B OpenSuSE Tumbleweed zypper upgrade problem · GitHub .

A while ago I had a "fsck.ext4: unable to set superblock flags on ROOT" on an SD card in a Raspberry Pi: it basically means the SD card is dead.
Back then Google found only one entry: [WayBack ] Bad Superblock – Raspberry Pi Forums

These are cool devices: the [WayBack ] LBS008AE and LBS005AE-R2, 10-100 Switches USB powered – Black Box .
Both are the size of a Raspberry Pi and USB powered.
The first is 8-port, the second 5-port. Ideal for a stack of Pis.
There are 5V powered 8-port Gigabyte switches from other vendors as well at around `1A (effectively using ~5W), but they are bigger.

As you know Tesla has thousands of 18650 batteries. The 18650 battery is a strong existence. So we made this 18650 battery shield for maker.
Features:
Battery protection(Over charge or Over discharge)
Micro USB port Input
Type-A USB Output
0.5A current charging
1 switch control USB output
5~8V Input Voltage
3V & 1A Output
5V & 2A Output
LED indicate(Green means full,Red means charging)
3V output port x3
5V output port x3
Charging can only be done at 0.5A, so using it as a sort of UPS seems not possible, but an interesting device nonetheless.
The other products referenced from the same page are interesting too and will undoubtedly bring me some new ideas for some projects.

Two links that help me identify the Raspberry Pi devices from my collection (which misses quite a few, but is too extensive to get them all right in the blink of an eye):
