New Raspberry PI 5

[mk-soft]

I needed something new to play with again.

So I treated myself to the new Raspberry PI 5. (As a bundle with raspi case with fan and heat sink, power supply, etc)
I use an external usb SSD as a drive. (EMTEC SSD X210 128GB)

The PI 5 is really much faster than the PI 4, compiling from the PureBasic IDE is more than 3 times faster.
The new fan control is better than described.

The PI 5 speed will be almost on par with desktops now.

That's right.
The programs also start very quickly (with SSD) and run smoothly.
Unfortunately, there are no running screensavers for Wayland for the Raspberry yet.
That's why I first switched to X11 with raspi-config and installed the xscreensaver.

There are some workarounds to get xscreensaver working under wayland:
https://www.linux.org/threads/xscreensa ... and.43543/
and also
https://sr.ht/~mstoeckl/wscreensaver/

But as long as you are happy with X11, no need to switch just for the sake of novelty

I had some time in the last few days to mess with this and it seems that the RPi people changed chips that control the gpio from pi4 to pi5. I bought the Pi5. Most of the libraries recommended don't work on the new hardware. Since Pi5 is it's own beast, it would seem that the RPi people should have provided a gpiSomething.so that's compatible with whatever version you buy. It's a very odd thing to sell a computer with gpio pins, but no clean way to get to them . Searching the web has you go down many rabbit holes and still no good solution. A shame.

I've written a few sketches for arduino and getting to the pins is a breeze, so it can be done if the manufacturer chooses to.

I did exactly the same thing wrt Wayland. There doesn't seem to be many pluses to it, just a whole heap of things stop working. I have not yet added an SSD, I've wasted a bit of time building it into an old NBN modem box with an 15w per side amplifier.
