    How Do You Make A Raspberry Pi On A Stick?

    a hackable media player “stick” with the Raspberry Pi built-in. We love that this Raspberry Pi CM4 TV Stick eliminates all the adapters and cables usually required to connect a Pi’s fiddly micro HDMI ports to a display and has heat sinks and an IR receiver to boot. Like a consumer media player HDMI stick, all you need to add is power.

    ClusBerry Rack houses up to four hot-swappable Raspberry Pi CM4 modules

    TECHBASE ClusBerry Rack supports up to four Raspberry Pi CM4 based modules which can be added and removed on the fly thanks to a lockable mechanism that reminds me of hot-swappable drives found in NAS.

    Using the same ClusBerry I/O mainboards as found in the earlier ClusBerry 9500-CM4 and ClusBerry-2M industrial systems, each Raspberry Pi Compute Module 4 inside the ClusBerry Rack offer one Gigabit Ethernet port, one USB host, one micro USB service port, and an RS-232/485 serial port.

    Raspberry Pi 4 8GB Gets Sneaky Update
    By Ian Evenden 4 days ago
    Doesn’t do much though

    The Broadcom SoC in the Raspberry Pi 4 Model B has been quietly updated to match the one in the Raspberry Pi 400, according to St Louis-based app developer (and more importantly, Pi Cast guest) Jeff Geerling.

    Geerling noticed the change after buying a new Raspberry Pi 4, an 8GB model, to replace a broken board, and spotting that one character in the model number on one of its chips had changed. The BCM2711 is the SoC (System on Chip), the whole brain of the Raspberry Pi housing its CPU, GPU, and the PCIe link that connects the USB ports. Previously, its model number has ended in B0T, but Geerling’s new baby has a model number ending C0T, matching that used in the Raspberry Pi 400’s SoC.

    It makes sense for Raspberry Pi to have done this, as it cuts down on the different chips

    From the tiniest carrier board to the best Industrial Pis on the market, the Compute Module 4 is powering a revolution in Raspberry Pi uses!

    But sometimes it’s hard to get one, and we’ll talk about that too! Watch to the end to see some of the other boards I’ll be testing soon!

    The Pi 400 As A PC Peripheral

    The Raspberry Pi 400 all-in-one computer is a neat little unit that is powerful enough to take on most humdrum computing tasks while doing an excellent job of freeing up valuable desktop space. But what about those moments when both the Pi and a PC are needed on the same desktop? How can the Pi and the bulky PC keyboard share the same space?

    [Gadgetoid] may have the answer, with a clever bit of software that presents the Pi’s mouse and keyboard as peripherals on its USB-C power port. If your PC has a high-power USB socket that can run the Pi then it can use the small computer’s input devices just as well as the Pi itself can. It’s fair to say that the Pi 400’s keyboard is not it’s strongest point, but we can see some utility in the idea.

    The Compute Module Comes Of Age: Say Hello To The Real Cutting Edge Of Raspberry Pi

    A Plethora Of Ways To Spin Your Own Pi

    Making a complex PCB can often be a daunting prospect for those of us who don’t do it for a living every day, so our first CM4 board from [Timonsku] shows that a CM4 project needn’t be complex at all. It’s a CM4 carrier board with a full-size HDMI socket, USB-A and C ports, as well as a microSD slot. A modest specification to be sure, but what sets it apart is the PCB itself. It’s a single-sided design milled with a PCB router, demonstrating that a CM4 carrier is simple enough to be created at home. Anyone really can spin up their own Pi! [Timonsku] hasn’t rested on his laurels though, producing as well the Piunora, a CM4 carrier with an Arduino footprint.

    Raspberry Pi Tablet Gets Radio Surgical Enhancement

    We always get excited when we buy a new tablet. But after a few months, it usually winds up at the bottom of a pile of papers on the credenza, a victim of not being as powerful as our desktop computers and not being as convenient as our phones. However, if you don’t mind a thick tablet, you can get the RasPad enclosure to fit around your own Raspberry Pi so it can be used as a tablet. Honestly, we weren’t that impressed until we saw [RTL-SDR] add an SDR dongle inside the case, making it a very portable Raspberry Pi SDR platform.

    Vulkan 1.1 Driver Comes to Raspberry Pi 4
    By Ian Evenden about 20 hours ago
    Graphics API forges ahead

    V3DV, Mesa’s driver for the Vulkan API on Broadcom graphics processors such as that found in the Raspberry Pi 4 has reached another milestone: compliance with Vulkan’s 1.1 standard. There hasn’t been an announcement as such, but an update to the project’s repository at freedesktop.org was noticed by Phoronix.

    the project is now capable of running FPS games such as Quake 3 on the $35 Raspberry Pi.

    While not the latest version of the API – 1.2 became available in January 2020 and is still being refined – it’s an important step forward, as it brings better compatibility with DirectX 12 for Vulkan, gives it multi-GPU support at the API level (potentially good for those using Pi clusters) and supports ray-tracing, geometry shaders, and advanced GPU compute functionality.

    Quake III was already playable on Pi with an earlier version of the driver

    Raspberry Pin hinta nousi ensimmäistä kertaa

    Raspberry Pi -säätiön johtaja Eben Upton pahoittelee blogissaan, että huolimatta kaikesta mahdollisesta varautumisesta komponenttipula on vaikuttanut erityisesti kahden tuotteen saatavuuteen. Nämä ovat minikokoinen Raspberry Pi Zero sekä kahden gigatavun muistilla varustettu Rasbperry Pi 4.

    Niinpä viimeksimainitun hinta on jouduttu korottamaan 35 dollarista 45 dollariin. Tämäm on samalla ensimmäinen kerta, kun suosittujen RPi-korttien hintaa korotetaan.

    Eben Uptonin mukaan komponenttipula saa käytännössä aikaan sen, että Raspberry Pi -kortteja myydään tänä vuonna noin 7 miljoonaa kappaletta. Tämä on täsmälleen saman verran kuin viime vuonna, vaikka kysyntä on edelleen kovassa kasvussa.

    Samalla Upton julkisti tiedon, jonka mukaan hinnaltaan nostetun 2 gigatavun kortin rinnalle tuodaan 1 gigatavun muistilla varustettu Raspberry Pi 4 -kortti. Sen hinta on 35 dollaria

    Reballing And A Steady Hand Makes A Raspberry Pi 800

    The all-in-one Raspberry Pi 400 computer is a capable device, but those seeking its maximum power may be disappointed by its 4 GB of memory. When the Pi 4 and Compute Module 4 have double that figure, surely the Pi 400 could catch up! A reddit user called [Pi800] rose to the challenge by replacing the 4 GB chip from the Pi 400 with the 8 GB chip from a Pi Compute Module, resulting in the so-called Pi 800, a working 8 GB all-in-one Pi.

    Planned crowdfunder for the four-bay NAS carrier board canceled owing to the semiconductor shortage — but the concept lives on.

    Wiretrustee Cancels Its Four-Port Raspberry Pi CM4 NAS Plans, Releases All Designs as Open Source

    Planned crowdfunder for the four-bay NAS carrier board canceled owing to the semiconductor shortage — but the concept lives on.

    A work-in-progress effort to create a carrier board to turn a Raspberry Pi Compute Module 4 into a four-bay network attached storage (NAS) system has been discontinued by its creator — with the design files now published under a permissive open source license.

    Wiretrustee unveiled its SATA carrier board a year ago, having been inspired by experiments maker Jeff Geerling carrier out with the Raspberry Pi Compute Module 4′s PCI Express connectivity.

    The small-footprint board accepted any model of Raspberry Pi Compute Module 4 and offers USB, HDMI, and Ethernet connectivity alongside a fan connector, battery-backed real-time clock, microSD slot, and four on-board SATA power and data connectors in a PCB designed to act as a backplane in a NAS housing.

    Sadly, while prototypes were created and a Crowd Supply crowdfunding campaign planed, the board fell short of a commercial realization.
