Some folks might have missed that memory prices on the whole are up [1] 90% since Q4. The memory used by the Pi 5 is up 700% [2]! Raspberry Pi are working the issue by releasing new memory variants that are cheaper[2]. Edit: You can still walk into a Microcenter and get Pi 5 16GB for US $289! 1. https://au.pcpartpicker.com/trends/price/memory/ 2. https://www.raspberrypi.com/news/a-new-3gb-raspberry-pi-4-fo...

I wonder if it be possible for pi to support cheap older generation of RAM modules? And thus use recycled RAM from old computers from scrap?

It's crazy how Raspberry Pi & Apple prices have moved in converging direction. Pi 5 8GB is $200 MacBook Neo 8GB is $600 (probably some edu discount available) Sure 3x the price, but it comes with - 256GB SSD, battery, display, keyboard, trackpad.. So the Pi has slowly become too expensive for weird one-off projects and also price competitive with a cheap Mac by the time you add all the stuff you need to use it as a c…

Not a completely invalid or uncommon take, but also not completely correct. People lament that it isn't the $25 like it used to be with the Pi 2/3, but ignore that you can get a Pi Zero 2 W (quad A53 cores like 3B, 512MB RAM) for https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/ I wish a Pi 5 (and RAM in general) was cheaper, but Raspberry Pi can't control that.

Is it at all possible to run 1080p video using Pi Zero 2 W smoothly with no jittering? What about launching a browser and playing a 1080p video from a streaming site? I am looking for a computer to connect to my internet-disconnected TV.

In my experience, yes to hardware-accelerated video from CLI--running in EGL mode, with no window manager, that RPi model works very well. (A C++ app that uses video as a texture can be surprisingly performant, too.) But no to playing video in a full desktop environment and browser, not smoothly--it's just too much overhead.

I've easily played 1080p video, but not using a full Linux GUI. The more effective way is to use a command-line video player like mpv that can leverage the hardware decoder and render to the frame buffer.

I made a project for a band to use on-stage where it would switch between videos by tapping a bluetooth foot pedal. The stompbox-style foot pedal buttons were just wired into an ESP32 acting like a bluetooth keyboard sending 1, 2, or 3. The key bindings for mpv were setup to instantly switch to specific videos for each number. It worked perfectly.

I have also used it to real-time 1080p stream my gaming PC from another room using Moonlight so that I could play in more than one location in my home. That was also running directly from the command-line.

But trying to use something like X/Wayland and proper GUI apps usually performs poorly. 512MB of RAM and the 1GHz CPU clock struggle with that.

I really struggle to see where this fits in to most use cases. The appeal of the Pi back in the first iterations was being a relatively cheap linux computer with GPIO.

You should really look at the Pi Zero 2 W. Similar capabilities to the 3B for <$20. The Pico 2 is also cheap and very capable if you don't actually need Linux. Most projects don't need a Pi 5.

Oof ... BLE 5 has some huge improvements over 4.2. BLE 5 stuff has been on sale for almost 10 years now ...

Hopefully this gets a refresh soon.

Yeah that's why I have so many ESP32-S3's around, no project I've done actually needs Linux and the boot times and SD card problems that come with using a Pi.

The value and capabilities of ESP32s are incredible. Most projects I see that use Linux to drive a GPIO would be better served by an ESP32 almost every time. They can even be coded using Arduino, and LLMs can produce Arduino code easily. The boot instantly, consume extremely little power, and are so small they make even a PI Zero look like a giant brick.

Zeros are just sold out everywhere through, no?

My home cluster is built from surplus Dell Optiplex desktops that I got from BYU Surplus and added some RAM (before RAM price went totally bananas) and SSDs to. I spent less than the cost of one of these Pis to acquire all of them together. I later added a large machine that I used to use as a Linux desktop, with a GPU and 64GB RAM, which I use for generating OpenStreetMap tiles.

> My home cluster is built from surplus Dell Optiplex desktops I used to do this as well and this is fine if you're able to source cheap power. But I'm in the UK, electricity prices are insane and I can't afford to run this kind of setup any more.

it's not unmanageable to do if you have plentiful and cheap access to area that can see the sun. My 'vintage' computing collection got a lot bigger when I switched to solar.

a big ask in most of the UK, though.

Some people seem to think raspberry pi is a consumer tech company and whenever a new model is released, the old one will be discontinued. They will complain about the product being changed and the company robbing them of a cheap SBC. I can only assume they don't actually work with the pi because if you spend just a minute looking at any reseller's inventory or even just the official website you will see they still ma…

I don't understand why it's so difficult for people to understand. If you're using the Pi as a microcontroller that you can run Python on, then just get the cheapest Pi that meets your needs. If you're using the Pi for computationally expensive tasks then pay more money and get the fast one. Personally I have a Pi 5 and it's perfect for me because I want small size but high performance. People say "just buy a real co…

N100-class minipcs are better at everything the pi 5 is doing except perhaps a bit of idle power and gpio.
