This is the sort of thing that should be documented by Raspberry Pi themselves. Somewhere like this - https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md You mean like where it says Note: As of the 4.9 kernel, all Pis report BCM2835, even those with BCM2836, BCM2...

That's not the way this forum works. It's run by volunteer folks who don't get paid to offer assistance. Where as one assumes the lecturer giving the course is being paid so you should be asking them your questions, and if you don't get a satisfactory reply then you should be complaining to who eve...

You can enter utf8 codes by pressing CTL+SHIFT+u ( cursor changes to "u") then typing the 4 digit code. Is that what you want ?
PeterO

(opse said CTL+ALT originally!)

A55 would be awesome... but I think it's too expensive.

That's an ARM core, not an SoC !

What were the metrics set to before you changed them ?
What did "route" print out ?

It isn't your Python script that needs to change. It is probably the IP routing configuration of your operating system that you need to modify. How so? Because that is what determines which interface is used to send each packet. The kernel has a "Routing Table" that can be viewed by running the "ro...

No more bloat, as the program is written in C++ Except that it pulled in a load of "qml" libraries (what evver they are) that weren't installed by default on my Mint-19 laptop. /var/log/apt/history.log show this.....

Did I read it correctly or not? - not on Raspbian?? available for Windows, macOS and Ubuntu In another thread it was stated that a Raspbian version is coming soon. But a Raspbian version is less important than the non-Raspbian versions as they allow first time users to get started using their exist...

[*]That Raspberry Pi Imager does not run in Raspbian. (Though it probably will eventually)

But it does run on the platforms that beginners are most likely to have access to, where as yours has a "Chicken and Egg" failure for beginners.

The CM4 announcement is more of a leak than an official announcement to me.

Do you have a sense of humour ?

Please think of something else to obsess about.
I'm surprised no one's commented at all on the CM4.
Quite.

The wires are normal jumpers. They are rated for beyond the Pi's needs. I would consider "normal jumpers" to be inadequate for providing the currents needed. They are only designed to carry the few milliamps of current that a GPIO pin can provide. The point is this however: there is no current spik...

Ah, you mean like those perfectly manicured support pages where you can search for a solution,

And the only answers they have refer to problems with their Windows 10 drivers

Your maths is wrong (even ignoring the fact it is a log scale)

Really ?

-2dB = 10 log10(P1/P2) dB

P1/P2 = 10^(-2/10) = 10^-0.2 = 0.63

100% - 63% = 37% reduction

The point is that a 2dB reduction is not "virtually the same" though as you say it may not be significant.

Note what OP said

Something that can be communicated over a phone to non-technical individuals and does not require mailing any more SD cards to the people I'm trying to help.

So all these suggestions that include "apt install" are not really very helpful !

I use Dual Fan Aluminium Heatsink Case for Raspberry Pi 4 from https://core-electronics.com.au/ - which I believe is the Pimoroni case This works well - my fan only turns on after a stress test.

I think it's a bit sad that so many people don't seem to know how to evaluate the results of an internet search to determine whether the returned results might be at all relevant to their problem. That's how learning happens, at least "back in the day". :lol: When I see people complaining about poo...

The power bank is only rated at 18W, that's 18/5 = 3.6A at 5V The only information I've been able to find on the monitor suggests it takes 2A at 5V, thus leaving only 1.6A for the PI.
