:raspberrypi: Raspberry Pi 5 is coming :raspberrypi:
With more than twice the speed of Raspberry Pi 4, and featuring our brand new RP1 chip, we’ve refined the Raspberry Pi experience.
It’s the everything computer. Optimised.
Priced at $60 for the 4GB variant, and $80 for its 8GB sibling, units are already available to pre-order from many of our Approved Resellers, and will ship at the end of October.
Okay, so let me tell you about my doorbell, from a #networking perspective.
When you push the button by the door, it sends a message over the #zigbee wireless mesh network in my house. It probably goes through a few hops, getting relayed along the way by the various Zigbee light switches and "smart outlets" I have.
Once it makes it to my utility closet, it's received by a Zigbee-to-USB dongle, through a USB hub (a simple tree network) plugged into an SFF PC. From there, it gets fed into zigbee2mqtt, which, as the name implies, publishes it to my local #mqtt broker.
The mqtt broker is in the small #kubernetes cluster of #raspberrypi nodes I run in my utility closet. To get in (via a couple of #ethernet switch hops), it goes through #metallb, which is basically a proxy-ARP type service that advertises the IP address for the mqtt endpoint to the rest of my network, then passes the traffic to the appropriate container via a #linux veth device.
I have #HomeAssistant, running in the same Kubernetes cluster, subscribed to these events. Within Kubernetes, the message goes through the CNI plugin that I use, #flannel. If the message has to pass between hosts, Flannel encapsulates it in VXLAN, so that it can be directed to the correct veth on the destination host.
Because I like #NodeRed for automation tasks more than HomeAssistant, your press of the doorbell takes another hop within the Kubernetes cluster (via a REST call) so that NodeRed can decide whether it's within the time of day I want the doorbell to ring, etc. If we're all good, NodeRed publishes an mqtt message (more VXLANs, veths, etc.)
(Oh and it also sends a notification to my phone, which means another trip through the HomeAssistant container, and leaving my home network involves another soup of acronyms including VLANs, PoE, QoS, PPPoE, NAT or IPv6, DoH, and GPON. And maybe it goes over 5G depending on where my phone is.)
Of course something's got to actually make the "ding dong" sound, and that's another Raspberry Pi that sits on top of my grandmother clock. So to get there the message hops through a couple Ethernet switches and my home WiFi, where it gets received by a little custom daemon I wrote that plays the sound via an attached #HiFiBerry board. Oh but wait! We're not quite done with networking, because the sound gets played through PulseAudio, which is done through a UNIX domain socket.
SO ANYWAY, that's why my doorbell rarely works and why you've been standing outside in the snow for five minutes.
With the #RaspberryPi5 releasing, don't forget how they boasted about hiring an ex surveillance cop, then ridiculed the people who criticized them for it.
Also remember how you weren't able to buy a Pi for months because they prioritized supplying their business customers.
I'm not buying #RaspberryPi products any longer, nor do I recommend them to my friends and clients. The Pi Foundation has become seriously out of touch.
Set up a #RaspberryPi-based #allsky camera on the backyard for a first test and, by chance, there was super strong #aurora with auroral corona (at zenith, overhead) early on Monday morning. 🤯
The Raspberry Pi 5 is 2.5x faster than the Pi 4 (sometimes more!), and I have the FULL rundown — let me walk you through it in this thread. #RaspberryPi#Pi5
The #RaspberryPi 5 is here and like its predecessor it supports decoding and displaying H.265 in 4K@60fps.
Some of you may wonder: does that really work on a modern #Linux / #FDO desktop? If my laptop fan starts spinning when playing such content, how can the PI handle it?
Here I'd like to draw your attention to a pretty cool feature we just introduced in #GNOME45 - support for YCbCr or YUV pixel formats in the system compositor (Mutter).
Behind the scenes, we’ve been working hard with our friends at the Sony UK Technology Centre in Wales (where your Pi is baked) to ramp up the manufacturing and production test processes. Things have gone a little faster than expected, and we’re happy to announce that the first mass-production units will ship to customers this week.
GOOD NEWS! I can confidently say: the Pi shortage seems to be wrapping up. Don't buy from scalpers, you won't have to wait long for a re-stock from local #RaspberryPi resellers.
This project is totally in keeping with the spirit of things around here. Thorbjörn Jemander did what any self-respecting tinkerer should do after securing a prized piece of retro tech: hack it with a #RaspberryPi to make it do something elaborately pointless.
The Commodore PET was released in 1977, and this one came back from the dead to fulfil the important task of playing videos from YouTube, a platform launched in 2005.
It's time for an #introduction, having just moved over from Fosstodon to a much smaller instance.
I've recently career changed, after three decades teaching physics and computer science in schools and colleges. I'm now an instructor in the aviation industry and enjoying the change of pace.
I have an occasionally updated #Gemini log, a set of #RaspberryPi computers running network services, and I started programming on a Sinclair ZX81 microcomputer.
I enjoy winge-bonding about the failures of politics, irritatingly smug tech billionaires and the stupidity of the #england national rugby team. I prefer calming countryside photos, happy tales and stories of positive experiences.
If your first thought when you hear that a company that makes computers and writes curricula that trains kids how to use computers proudly hired a spy cop and gave the middle finger to those who raised ethical concerns is to defend the company and the spy cop in question, you should take a moment, stop what you’re doing, and give yourself a firm slap in the face.
It won’t change anything but it’ll make me feel better at least.
Today we're releasing the newest version of Raspberry Pi OS, called Bookworm, like the #Debian release it's based on.
In Raspberry Pi OS Bookworm, we're launching some major changes to the #RaspberryPi Desktop: the Wayland display system, PipeWire sound interface, and NetworkManager network controller bring increased responsiveness, flexibility, and security. We're also offering Firefox as a browser option alongside Chromium.
This one took weeks to write. It's about me finding a way to significantly reduce the power consumption of a Raspberry Pi Pico W working as a weather station, collecting environmental data.
I am also writing about powering the Pico using solar panels, and this time it's a success, my weather station can now run indefinitely, powered by the sun!

Announcing Raspberry Pi 5, coming in late October: over 2x faster than Raspberry Pi 4, featuring silicon designed in-house at Raspberry Pi.
