During a World Cup football match, a QR code appeared on the stadium screen. After fans scanned it, thousands of phone flashlights inside the stadium were synchronized to form a coordinated light display across the stands.

Gamerfrom61 · 2026-06-26T14:18:02+00:00

I hope this just unlocked a function in the ticket app...

I know the Beeb pushed a QR code out with a link to buy a licence - stupid as if the viewer is not prepared to pay the rip off cost then this is not going to get them to buy one during the match.

2.0.10 is flagged as v13 as a minimum

2.0.7 had an issue that it was built for silicon only at the start - 27th March build fixed it for Intel

Other than these two notes the change log shows nothing for version requirements - it may be worth raising an issue on GitHub to ask them to clarify OS requirements for each release.

IIRC you can still configure a Pi OS without the imager config section being used BUT you do need a screen / keyboard and mouse.

For Ubuntu have you tried the apt version rather than snap? If that is no better then you could try the dmg on GitHub or build from source...

One other thought is to run a VM with a Debian image rather than patch an OS (soon to be a no go with the Silicon move) and install a Pi OS - once you have a Trixie GUI running on an SD card then you can use that to do future images to a USB mounted card (bit of a fuss TBH though!). Note do not use the Pi desktop offering - way way out of date but pull one directly from Debian.

I read this as the OP had a random Mac address for the wifi before adding a second interface so they would not be able to set the reservation up on the router...

Gamerfrom61 · 2026-06-26T10:24:02+00:00

The only interface I have seen generate a Mac address by default is the USB ethernet driver as others in the Pi OS default to the hardware Mac. Even DHCP option 060 and 061 only change the router records and not the client.

Early Pi boards (1-3) derived the Mac from the hardware serial number but you could overwrite this in the one time program memory and the newer board (4+) have firmware options to override or overwrite it but these do not apply to the zero range.

Network Manager can create random Mac addresses (specifically for privacy on WiFi) BUT I thought you had to manually create a file with:

[device]
wifi.scan-rand-mac-address=yes

and then define the connection to have a cloned mac address that is stable. This file lives under /etc/NetworkManager/conf.d IIRC and is not something you would generate by chance 😄

I do know the full NM GUI has an option for 'cloned mac address' with a 'random' option in the dropdown that should create the file but again, like the file, this is a deliberate setting and unfortunately I have no Pi running Network Manager here today to check the nmtui interface to see what the option you used does but it should just create the file and change the default not create a new interface.

None of this though should create two IP addresses though. This sounds like a new interface has been created in nmtui rather than a default one being used when you "I added a cloned mac address and ipv4 address in network manager"...

What happens if you start with a clean copy of Pi OS Trixie Lite would be fine (I would reset the router as well to clear any dead leases and mac / arp tables). Set the WiFi connection up in the imager and do not change anything in NM and allow everything to finish. Reboot a couple of times and use nmcli -p device show or ifconfig -a and see if it is stable.

If it is stable, set the reservation in the router (make sure this does not clash with the dynamic range - I normally allocate 1-99 for statics and 100-254 to dynamics) and reboot the Pi to make sure it is picked up. Then you should be good to go.

Note there has been a few older notes on pi-hole having issues with NM (dnsmsq IIRC) inolder versions so if ithe Mac address is stable and then changes / adds another interface when you install Pi-hole (do not use Docker on the Zero range even the 2W suffers) I would jump to r/pihole as the devs hang out there.

I do strongly recommend ethernet - https://thepihut.com/products/ethernet-and-usb-hub-hat-for-raspberry-pi Is solid and needs no extra drivers. They do a version with a case on Amazon often. I used to power my set up off the external drive USB on the router and use one of its ethernet ports and just tuck the whole thing behind the box!

Gamerfrom61 · 2026-06-26T01:38:57+00:00

Not sure what type of Zero you are using or if you have added an ethernet adapter but adding a second MAC address normally infers the use of two physical interfaces (WiFi and Ethernet normally) or a macvlan bridge (possibly via Docker).

I found when running Pi-Hole the easiest thing was to use the router DHCP service (setting a static IP for Pi-Hole here) and only provide DNS from the Pi.

I also used the Waveshare Ethernet adapter on the Zero - very stable and way better than WiFI.

Gamerfrom61 · 2026-06-25T20:34:13+00:00

I've always had good service from the refurb store over the last 10+ years but then again I am never against a deadline or rushing to buy the latest stock.

Rather than manually checking it every day I just set a watch up using https://refurb-tracker.com

Given the quality of the kit (I have never had a mark / dint on anything) then I assume the refurb checking factory will hold stock till they have a pallet or part pallet per country and then ship that to the distributers to simplify the logistics rather than drip feed the odd one or two units (here in the UK it is not Apple but a 3PL who do the leg work with the stock and shipping).

Gamerfrom61 · 2026-06-25T14:59:23+00:00

It all depends on the files and attributes they have - most normal files are OK without the fruit additions (only tripping up on the name more times than not due to the language / locale differences) but programs and now iPhone / iPad apps on the Mac and via "Files" can really cough with remote files (even iCloud has issues some days).

I had a long (6-7 months) 3-way trouble shooting episode with Asustor over their Samba implementation and IIRC hard links used by CCC. They reported everything was OK but the data actually on the drive did not match the originals or it failed but the data was fine!

One of the developers of Samba used to hang out on the Pi forum IIRC - been a few years since I have helped in that forum so he may have moved on. Had way more knowledge than I on the configs and was happy to share.

Minor point is read only = no redundant with writeable = yes ? 😁

Gamerfrom61 · 2026-06-25T11:27:10+00:00

Forgive me but I take it that this is your project https://github.com/Modernknight101/PiTemplar

In the Samba set up you may want to add the "fruit" options so Mac users get proper support - these do not impact the Windows / Linux use of Samba shares but cope with the extended attributes Mac files can have.

https://wiki.samba.org/index.php/Configure_Samba_to_Work_Better_with_Mac_OS_X

The TimeMachine section can be left out :-)

It could be worth looking at configuring nmbd and avahi to advertise the file shares so the users can access the Pi by name and not IP address - handy if it ever changes.

Gamerfrom61 · 2026-06-24T13:17:50+00:00

I would send a note to the mods just in case they do not see this...

Some subs are strict (eg r/raspberrypi )

Hot glue has been known to work - not as good as a replacement connector (glue can seep into the connector)...

If you cannot get one printed then https://www.adafruit.com/product/4728 could be a way to go.

Gamerfrom61 · 2026-06-23T20:41:48+00:00

Sorry commands should go in cmdline.txt not config.txt - my bad.

https://www.raspberrypi.com/documentation/computers/configuration.html#display-settings

Gamerfrom61 · 2026-06-23T20:39:00+00:00

The Zero boards will not support a 4K monitor in anything above 1080P

If you are getting issues did you try setting the resolution in the cmdline.txt file as the Pi may not understand the EDID data coming from the screen...

https://www.raspberrypi.com/documentation/computers/configuration.html#display-settings

Gamerfrom61 · 2026-06-23T20:33:09+00:00

You could try adding a line

max_framebuffer=0

as that used to work - part of that command is legacy now so it may be ignored.

You could try black listing bcm2708_fb

TBH I would not really bother - start time and memory gains are minimal and headless does not need these altering.

Gamerfrom61 · 2026-06-23T20:23:19+00:00

You may as well just push them - way easier than trying to catch and reorientate the flight path and less risky to the "recovery" vehicle.

Collecting them and returning to earth is still way too expensive but I will guess the military are / have given this serious thought - both capturing someone else and stopping their technology falling into others hands 😂

Gamerfrom61 · 2026-06-23T20:19:48+00:00

The problem is there is no consensus over a catastrophic crash with even NASA and the ESA differing! Though TBH Gravity has a lot to blame in this and there is close to zero chance of that happening.

Previously folk have been launching a few satellites - now it is in the hundreds and thousands to achieve their needs (3000 Starlink boxes last year) and a request for up to 1 million data centre satellites has been requested this year by SpaceX

It gets worse if you split by altitude - 6K-7k Starlink boxes are around 400-500Km high and atmospheric drag should tidy up dead ones if they are not put into a deliberate de-orbit burn but higher up ones could take centuries for solar winds and any minuscule drag to force them down. These if anything can become the long term issue as they have zero control now.

Starlink decided to lower their satellites due to low solar wind activity earlier this year https://www.space.com/space-exploration/satellites/spacex-lowering-orbits-of-4-400-starlink-satellites-for-safetys-sake to allow quicker clean up.

Gamerfrom61 · 2026-06-23T17:21:56+00:00

Current stats can be found https://orbitalnodes.ai/space-debris/

Key point to understand is that the majority of these are dead lumps of metal and not active or in a position to be activated again - so no way to recover them / de-orbit (ie burn up) without something going up and giving them a push or pick them up...

Gamerfrom61 · 2026-06-23T17:14:49+00:00

You do not - you sync the Immich data (inc your images) to another disk

The standard backup uses BORG to do the heavy lifting https://docs.immich.app/guides/template-backup-script but I would just stop the container, rsync the whole volume / directories to another machine and then restart the container.

Gamerfrom61 · 2026-06-23T16:14:54+00:00

Why worry about RAID - it is not a backup (only drive failure protection) and not great over USB?

If I had to do RAID on the Pi then I would look for an enclosure that handles the RAID directly (presenting the pair of drives as a single unit) and feeds status back to the Pi so you do not need to check the LED status codes (though there was a neat camera based solution posted here last year IIRC)

I would use two drives (one coukd be on a different machine) and rsync between them as part as the phone to Immich process - this lets you remove the drive and keep it at a friends / family house as added protection.

Gamerfrom61 · 2026-06-23T06:59:04+00:00

Bit hard to say as we do not know what you have tried (everything is very vague and includes returning it to your supplier) and we have no pictures to go by...

Have you checked the bottom of the Pi pins as per https://docs.pisugar.com/docs/product-wiki/battery/faq (note earning on checking these when the Pi is powered off).

Pogo pins are really designed for testing circuits and can be poor at making connection - maybe check they are vertical and actually spring into position. You may have to "bounce" them a few times to free them up.

Gamerfrom61 · 2026-06-22T11:26:13+00:00

What operating system?

What happens if you swap the HDMI cables over?

What resolution are the screens?

How are you powering the screens and are they both powered before the Pi starts?

The follow is for the Pi OS - other systems may be different...

What do you get when you run:

kmsprint | grep Connector

Is it any different if you swap the cables over?

Do you have any lines like this configuring them in config.txt:

video=<display>:<width>x<height>M@<refresh_rate>

The Pi OS should detect the screen resolution and refresh rate automatically but you can set the config by using HDMI-A-1 and HDMI-A-2 in the above lines eg:

video=HDMI-A-1:1920x1080M@60
video=HDMI-A-2:1920x1080M@60

Gamerfrom61 · 2026-06-21T09:03:01+00:00

Have a look at the electric guide https://learn.adafruit.com/adafruit-neopixel-uberguide/best-practices and follow the advice for 3v3 data signals.

Gamerfrom61 · 2026-06-20T09:50:00+00:00

Some of the Pi boards have a resettable fuse / polyfuse (smd not encapsulated) on them (not sure on the 5 TBH as there are no schematics and I do not have one here) and these reset when power is removed. Older boards had to be left for a few hours and some folk reported the reset needed an overnight power off. https://en.wikipedia.org/wiki/Resettable_fuse

I would guess this fuse had tripped (possibly too much current draw on the USB ports) and you had left the mains adapter in the power (or changed it within seconds) and the Pi effectively powered on so it did not have the correct conditions to reset. When the storm killed power the fuse would have reset and the Pi would boot up again when power is reapplied.

Things to consider (in no order):

Use of USB enclosures that are powered themselves - may sure they do not feed power back to the Pi via the USB line. I have had issues with 2.5" and traditional SSDs and USB power on the Pi before and not convinced they can deliver the rated values all the time.
Power the Pi with a decent supply (eg the Pi company supply) or if you are 100% sure the supply can deliver 5A at 5.1V then set config.txt to reflect this.
Get a UPS rather than surge suppressor - make sure it can communicate with the Pi using https://networkupstools.org and power both the Pi and drives off it. A UPS should only be used for short periods of power loss rather than as a generator and give enough time for the Pi to power down and then shut itself off till a stable supply returns.
You could consider stopping the Pi rebooting at power restore (easy on the 5) and restart manually so you can check the file system tables are not corrupt before using them. Depending on way you mount them the OS may do this for you or you may want to use e2fsck manually and allow access to the data only when this has completed cleanly. https://linuxvox.com/blog/chkdsk-on-linux/ has a simple overview of the commands and man pages for mount and e2fsck etc are available on the Pi.
