Another thing to try: [Wayback/Archive] makerbymistake on Twitter: “Can’t help myself and have to post more pics of this thing. Cheers to @Raspberry_Pi for providing great documentation on how to make a #CM4 carrier board. Thanks to so many folks that shared their designs also. So many more ideas in my head, so little time.”

Hopefully a newer and more reliable “Computa Pranksta” mouse jiggler device will ever be released
Posted by jpluimers on 2024/05/30
For my link archive as this was a cool idea, but for many their device didn’t last that long:
[Wayback/Archive] ElectricRCAircraftGuy/eRCaGuy_ComputaPranksta_Support: Public support for my “Computa Pranksta” mouse jiggler device I sell on Amazon and elsewhere.
This device is a mouse jiggler. It keeps your computer awake. It can also be used to have some fun with your friends (please don’t take it too far–it’s meant to be used in good, friendly gest–not for any type of malicious purposes).
Notes:
- There are software based Mouse Jiggler implementations as well; I wrote about one of them a loooooong time ago in Mouse Jiggler – MouseJiggle.exe will (virtually) move your mouse cursor so the screen saver does not start.
- I have a bunch of “original” USB Mouse Jigglers of which there are compact and long ones. I forgot I had ordered the compact ones too, so I got reminded when I decommissioned the old kiosk machine after my mom passed away and had to lookup what a [Wayback/Archive] cru mj-3 – Google Search was (:
Links on those USB Mouse Jigglers below, but first some links on the Computa Pranksta:

Ivan Kuleshov on GitHub – Uptime-Lab/KVM-rack-stand-for-16-Mac-minis
Posted by jpluimers on 2024/04/11
If you ever need a large bunch of Mac minis in a data center, then start reading at [Wayback/Archive] GitHub – Uptime-Lab/KVM-rack-stand-for-16-Mac-minis.
The repository by Ivan Kuleshov has all information you need, including scripts for Pi-KVM, and 3D printing STL source files.
It was covered in [Wayback/Archive] The MagPi issue 139 — The MagPi magazine (direct [Wayback/Archive] MagPi139.pdf; it’s too large for [Wayback] Goole Docs on-line viewing).

Raspberry Pi And The Story Of SD Card Corruption | Hackaday
Posted by jpluimers on 2023/10/02
[Wayback/Archive] Raspberry Pi And The Story Of SD Card Corruption | Hackaday is long and worth reading.
For me the most important bits are how to prevent SD card wear:
- use good quality power supplies
- put write-heavy operations to SSD
- if it suits your use-case, use OverlayFS
The first is always a good idea. It is the primary reason all our electronics live behind a UPS:
- before doing that we lost too much equipment due to brownouts
- all equipment survived the electromagnetic pulse (EMP) after a 2018 lightning strike
In addition, I posted my personal experience (Samsung microSD cards last way longer than SanDisk cards) on Twitter:
[Wayback/Archive] @hackaday I’m have been running a few Raspberry Pi systems with 8-32Gb micro-SD cards as web-dashboard with refreshes every few minutes or so: much write access. When using Sandisk (no matter the type) they last about a year, Samsung (no matter the type) cards last multiple years.

EMP
We had a lightning strike in the evening on 20181111 some 50 meters from our home.
It killed immediately killed this (some pictures further below):
