Raspberry Pi's not having easily identifiable memory capacity printed on their PCB is highly inconvenient...

Run your own LLM on a Raspberry PI because why the fuck not!

Agree with everything @localden writes in this post on the benefits of the #RPi-based #PiHole

https://den.dev/blog/pihole/

Have been using a PiHole for 3 years +, I couldn't go back to not using one.

The PicoCalc uLisp Machine is a Clockwork Pi PicoCalc handheld computer that runs uLisp, a Lisp implementation for microcontrollers.

The Clockwork Pi PicoCalc features an RP2040/2350-based Raspberry Pi Pico or Pi Pico 2 board, and has a nice 320x320 4" colour IPS display and keyboard. uLisp provides a rich environment and tools.

Tak mi umřel #HomeAssistant na #RPi4 se SD kartou tak, že se dostal do bootloopu.
No nic, asi si dám od HA chvilku pauzu, dokud to nepostavím na něčem pořádném. RPi se SD kartou je opravdu spíš jen hračka na testování.

Zum Thema #Vögel im #Garten habe ich mal was mit dem #raspberrypi gebastelt.
Die #birdnet Erkennung läuft echt super!

I was tired of counting pins when working with electronics like the Raspberry or ESP32, so I created a simple editor that generates pinout diagrams that fit right onto the board's pins.

"In this feasibility study we investigate if vocalising near-coastal fin whales can be widely detected and located with onshore seismometers... we establish that fin whale song can be detected with onshore seismometers up to 5.5 km inland, across multiple marine environments, globally. Individual creatures can be located and tracked through the analysis of seismic wave properties."

On Setting Up a Raspberry Pi 2 as Off-grid Server (2015) - Read how I set up my solar-powered RPi2 (previously a Model B then a B+) to take on load from servers elsewhere on the Internet... #RPi #frugal #offGrid - https://www.earth.org.uk/note-on-Raspberry-Pi-2-setup.html

How can I tell which is going to last the best in a hard working Raspberry Pi?
I don't see any 'read/write cycles' data.

Lately I've been doing more #SelfHosting again due to the current situation. Of course, I'm paying particular attention to power consumption and noise. After good experiences with the #ARM64 architecture, even with power-hungry applications such as Mastodon, I'm now using the smartphone technology for my homeservers, too.

There are #SBCs with more open hardware, but the #RaspberryPi is widely available, well documented, powerful and inexpensive. And it is available with up to 16 GB of RAM.

Anyone operating a server on the Internet must install #security updates quickly. However, many people forget to restart running software so that the new version runs instead of the old one. The #needrestart tool helps with this on Debian-based Linux systems, which unfortunately is usually not pre-installed.

On my Raspberry Pi 4, needrestart always runs correctly (automatically after apt upgrade). On my Raspberry Pi 5, however, I first had to create a configuration file as described by the main developer here:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Previously, the tool always claimed that a reboot was necessary because it thought an outdated Linux kernel was running.

Next, I want to activate #LUKS hard drive encryption on both raspis. Unfortunately, this is not as easy under #Raspbian or #RaspberryPiOS as on other Debian systems. If you have managed this: Please let me know how you did it!

In letzter Zeit mache ich aus gegebenem Anlass wieder mehr #SelfHosting. Natürlich achte ich dabei besonders auf den Stromverbrauch. Nach guten Erfahrungen mit der #ARM64-Architektur selbst bei leistungshungrigen Anwendungen wie Mastodon setze ich jetzt auch zuhause auf auf die aus Smartphones bekannte Technologie.

Es gibt zwar #SBCs mit offenerer Hardware, aber der #RaspberryPi ist überall erhältlich, gut dokumentiert, leistungsfähig und preiswert. Und es gibt ihn mit bis zu 16 GB RAM.

Wer einen Server am Internet betreibt, muss zügig #Sicherheitsupdates einspielen. Viele vergessen aber, laufende Software neuzustarten, damit die neue Version läuft statt der alten. Dabei hilft auf debianbasierten Linux-Systemen das Tool #needrestart, das leider meist nicht vorinstalliert ist.

Auf meinem Raspberry Pi 4 läuft needrestart schon immer korrekt (automatisch nach apt upgrade). Auf meinem Raspberry Pi 5 musste ich aber erst eine Konfigurationsdatei anlegen, wie es der Hauptentwickler hier beschreibt:
https://github.com/liske/needrestart/blob/master/README.raspberry.md
Bis dahin behauptete das Tool immer, dass ein reboot nötig sei, weil ein veralteter Linux-Kernel laufe.

Als nächstes will ich auf beiden Raspis die Festplattenverschlüsselung aktivieren. Das ist unter #Raspbian bzw. #RaspberryPiOS leider nicht so einfach wie auf anderen Debian-Systemen. Wenn ihr das geschafft habt: Schreibt gern eure Tipps!

#TIL: #RaspberryPi5 doesn't support #WakeOnLAN

So how am I supposed to reduce power consumption when not using our #LibreELEC setup on #RPi?

I do have Shelly Plug S available but I guess that I'd need a remote shutdown command before turning off power. Furthermore: how do I enable auto-boot when power resumes?

Any ideas?

It is amazing to see how good software does the job and stays out of your way. Example of this is #PiHole that is for years now running on tiny #RPi 3A+ without any problems and serving all clients in my network.

I just received a ClumsyMIDI Pi Hat I've setup with a Raspberry Pi 3 and the MT32-Pi software, to use with my Atari 520ST. Giving Ultima IV a listen.

$49 from Tindie. Good so far!

I just bought a lifetime #plex pass, after trying it for 6 months or so. I only use it for #plexamp to stream #music #flac from my #synology #nas to my #linux laptop, #rpi with #allo #boss2 #dac and #android phone. I also created an account for my almost 80-year-old father so he can join my server and library.

I came from #roon which I enjoyed a lot, but due to different reasons I made the switch. Plexamp provides such a seamless experience, I really can't wish for more. Keep up the good work!

Just finished the #RPi board support with #uboot #EFI in our beloved MTDA. First tried with the RPi EDK2 implementation, but that is far from being usable (who had the idea to convert a DT into ACPI tables???).

Even with Linux 6.12 many things do not work OOTB, like the RPi DTBOs cannot be used with the Kernels DT. Hence you manually need to port them - which is not trivial. #debian #linux #oss
