Introducing Pixie; yet another GNSS disciplined Raspberry Pi timeserver setup. There are a number of low-level tweaks including a realtime kernel build, per-CPU process isolation, PTP grandmaster time support, and NTP server support. Check out the wiki for more details!

@elkcityhazard Would #FreedomBox be a good solution? It has WordPress.
I have #NextCloud running on a #RaspberryPi with Debian and I'm thinking of migrating to the FreedomBox install for more of my own cloud services.

ELECTRICAL POWER SUPPLY QUESTION
Can anyone here sanity-check the #electrical #power solution I've ended up planning for my next automated #insect monitoring tool?
This will be a unit running on mains power. It includes a #RaspberryPi 4B controller (also running a #camera and various sensors), along with a number of high-powered #LEDs (to attract insects and to illuminate photos).
The #RPi requires 5V supply and I am using an A009 BuckBlock to deliver constant current for the LEDs. This works optimally with a 24V supply.
The RPi will turn the lights on and off using a relay.
At present, I'm thinking that the best approach is to power the whole unit with a 24V AC-DC converter and then use a second 24V-5V converter to step down this DC for the RPi.
That means three power converters are required. In this diagram:
The cyan converter is for mains (ground is back through this converter, but the diagramming tool was not good for representing this).
The yellow converter steps down for the RPi power.
The pink converter delivers constant current for the lights.
Am I missing something? Can this be done better? Will I need additional capacitors to stabilise the RPi voltage when turning on the lights suddenly draws down an extra 27W, or should a decent step-down converter handle that?
TIA for any assistance.

Does anybody know if there's really an advantage to update #RaspberryPI from #BookWorm to #Trixie? The recommended way is to reflash the SSD/SD Card, which I currently don't want to (because everything is still running fine and I'm still getting updates). So I wonder if anybody has a real world advantage that might justify the necessary work?

Hat jemand zufällig günstig einen Raspberry Pi Zero2w, Raspberry Pi 3, Raspberry Pi 4 oder Raspberry Pi 5 abzugeben? 
Mein Pi 3 B ist leider schon immer suizidal unterwegs und 3D Drucker debuggen (bzw generell irgendwas mit diesem Pi tun (*erinnert sich an Homeassistant oder Pihole darauf*)) mit einem Device, was random stirbt und 3-20 Wiederbelebungsversuche braucht ist irgendwie wenig spaßig... XD

Hey #Fedieltern, kennt Ihr eigentlich das #RaspberryPi-Projekt #Mupibox?
Die unabhängige Lösung statt Toniebox oder dem #Hörspiel-begeisterten Kind Zugriff auf Hörspielstreaming-Plattformen zu geben. Habe die Box damals gemeinsam mit den Kindern gesägt. Elektronik und Programmierung sind recht leicht. Hörspiele, Podcast, Hörbücher drauf und per Bildschirm auswählen.

🚀 Mình vừa lắp Pi 5 (16 GB) + Radxa Penta Hat (4×500 GB HDD, 1 TB SATA, 2 TB USB3). USB dùng cho Immich, SATA cho Home Assistant. Muốn tự xây mail server, website, giảm phụ thuộc vào dịch vụ trả phí. Hỏi cộng đồng: nên ưu tiên dịch vụ nào, có thể gộp trên cùng HDD không, và cách sao lưu nhanh cho HA chịu tải nặng? #RaspberryPi #HomeAssistant #Immich #DIY #Server #CôngNghệ #TựDo #Mạng
