:pika: Whoa!
I just realized my #RaspberryPi2 and #RaspberryPi3B are 10 and 7 years old.
No wonder they were struggling haha. Time to find new uses for them. Thinking one will continue as #Kodi box just for the #RV I just want to find an elegant way to add it to the #TV. For the other I've tried it as a #HomeAssistant server but, I am thinking it is time to try and set up a #NAS. Wish me luck!
#RaspberryPi2 ei ole nopea, mutta hyvin tuo on kotitalouden nimipalvelimena pyörinyt jo kohta kymmenen vuotta – ensin #Raspbian'illa, sitten tovin #Ubuntu'lla ja nyt jo jonkin aikaa #FreeBSD:llä. #atkjuttuja

#FreeBSD:n päivittäminen muilla kuin #Tier1:n alustoilla (ts. kaikki paitsi #amd64) onkin varsinainen rumba, koska se pitää tehdä lähteistä kääntämällä. #RaspberryPi2:ssa se tahtoo olla h-i-d-a-s-t-a. #kotijuttuja #atkjuttuja #miehenelämää
Und mein #RaspberryPI2 so:
Wie?? #python311 ??
Also ne, das musst du erst mal von Source compilen...
@blhue Had a recent experience where I ordered a #RaspberryPI3 from Amaxon and was sent an open box with a legacy #RaspberryPi2 inside. Guess someone got a FREE upgrade at #Amazon and my #TIME expense to return it back again.
Coses que he après de la patacada d'abans d'ahir a la nit:
- Una #RaspberryPi4 aguanta una instància #Mastodon o #Pixelfed tranquilament. Cal ajudar-la amb un disc SSD i el media a un CDN, però tira bé.
- Tenir el reverse proxy externalitzat també ajuda a relaxar la instància, però simplement mous el problema a un altre host.
- Tenir el reverse proxy en una vella #RaspberryPi2 dirigint el tràfic de 3 instàncies no és bona idea. No només pels 32bits, la ethernet és de 100Mbit/s i es satura.

Today's #3dprinting is for the #retrogaming corner of my office. (The test run of VitaDockPlus worked great on an original #raspberrypi, but it is time to upgrade to a #raspberrypi2 in a fancy case.)

Je suis parti d'un base de Robby RP5 dont j'ai viré toute l'élec. J'avais déjà monté un truc avec des meccano dessus et un #raspberrypi2, mais c'était un peu brinquebalant, et le Rpi était alimenté par un chargeur USB encombrant.
Having fun with #OpenBSD, #RaspberryPi2 and #PICO8 :flan_cool:

Free Your Pi With This Bare Metal Programming Environment
[Rene Strange] has graced these fair pages a short while ago with a sweet Raspberry Pi software based poly synth, with a tantalising reference to it being a bare metal application. So now, we'll look into circle, the bare metal programming environment that it is based upon. The platform consists of a large set of C++ classes to access the hardware as well as perform tasks such as task creation and scheduling in the cooperative multitasking, multicore environment. Supporting all Raspberry Pi boards from version 2 onwards (not including the Pico!) in both 32-bit and 64-bit flavours, the environment is pretty complete. Classes are provided for USB, networking, FatFS, as well as more mundane tasks such as dealing with interrupts. On top of these classes there are a pile of application-specific libraries, covering functions such as display interfacing, GUIs using a variety of frameworks, and some more esoteric applications such as interfacing to a Pico, and even sending the system log to a remote web browser!
Classes and libraries however, don't always help by themselves, which is where the 42 (yes, we know) code examples come in very handy. They've provided example applications for some fun stuff like drawing Mandelbrot fractals to the display, as well as some more mundane tasks that we have to deal with such as getting that pesky DMA controller to play nice with the SPI hardware. All-in-all, this looks like a great set of tools for taking full advantage of some fairly beefy hardware for your next embedded project that needs plenty of resources, but not all that unnecessary operating system stuff.
Perhaps not quite as complete as circle, but we've seen a fair few Raspberry Pi Bare metal projects over the years, like the Nerdsynth, based on the PiZero, and this neat little bare metal assembly language clone of starfox.
Thanks [Ruhan] for the tip!

Finally, the Venerable Vectrex Gets a Mini Makeover
It appears that every great console is bound to get a miniature remake: we've had the PlayStation Classic, the Mini NES and SNES, and even a miniature Sega Genesis/Mega Drive. But one great console that was sorely missing from that list, at least according to [Brendan], was the Vectrex. So he went ahead and built a fully-functioning miniature Vectrex Console.
If the name "Vectrex" doesn't ring a bell in your mind, you're not alone: a commercial failure, it was quickly forgotten by most following the 1983 video game crash. But it has retained a cult status among enthusiasts due to its unique design featuring a monochrome vector monitor, onto which you can place transparent overlays to obtain a sort-of color display. Its games can now all be emulated using software like RetroPie, which is what [Brendan] chose to run on a Raspberry Pi Model 2 that he had lying around.
As for the display, he settled on a Pi-compatible 3.5″ TFT device. Hooking it up to the Pi was easy enough, but getting the image rendered in its proper portrait orientation was quite a headache, requiring endless fiddling with drivers and configuration files.
Once he got this working, [Brendan] set to work designing a miniature copy of the Vectrex's original case. It took a few iterations and several 10-hour runs on his 3D printer before he ended up with a sturdy case that securely held the Pi and its display in place. A few more hours of printing later he also had a handheld controller, which he based on an Arduino Pro Mega. The Arduino reads out four regular pushbuttons and a joystick, and communicates with the Pi through a coiled USB cable.
The end result, as you can see in the video embedded below, is the cutest little Vectrex we've ever seen. It's really the opposite of this big-screen Vectrex project. We've also seen a Vectrex projector, and even one with a real color monitor hacked in.

Quiero montar un #openmediavault #NAS para tener un servidor de archivos local.
Me gustaria aprovechar la #raspberrypi2 B y tengo el típico HDD de WD mecánico que se alimenta por el mismo USB y que almenos en antiguas raspis no tenían potencia para funcionar.
He visto unas placas de expansión que sirven para esto y luego la versión ¿"chapucilla"? editando un archivo de config en /boot.
Alguien lo ha probado y decir si es seguro para la durabilidad de la placa.
After removing the adhesive side of the LED strips the other day, I put some solder on the pads. All in all I repeated this step for 270 pads.

For the big LED panel project I finally found the time to cut the strip into 45 parts. Each 5 LEDs long. Also removed the adhesive pads of them, because it does not stick to 3D printed parts well. Going to use hot glue for this.
