Re: Raspberry Pi 4 temperature

Feel free to disagree with me, but it would be nice to actually say what you're disagreeing on, and what you're calling "half-formed opinions". They're better than just blatant criticism without any ground. Back to frying eggs on a pi 4. I'm not disagreeing with you, because that would imply there ...

Re: Back Voltage from USB Hub

On a positive note, you could use one of the hub's USB ports and power a pi with that. As long as the powered hub gets more than 2,5A at 5V (1A at 12V) on the input, you can save cables there. (Meaning using data connection + power connection to the hub, for a more stable power). The problems usuall...

When you look at the sales of the 4B, you can clearly see there's a market for a pi desktop replacement , and for many, the 4B isn't that one yet.

I actually had exactly the same idea. The OP was 1 year ahead of me there. But then again, I only have my Pi 3B+ now for 2-3weeks. The Pi 3B+ uses +1.5A of power draw in fractions, not continuous.

Re: Raspberry Pi 4 temperature

Since you have a quad core, you'll want the speed of each core to be ~1,5Ghz for snappy response, and ~1,2Ghz for acceptable response.
Anything below 1-1,2Ghz gets a sluggish GUI experience.
It at least has the benefit of faster RAM, but the Pi Zero W only operates acceptably at 1.1Ghz.

Re: Dual redundancy raspberry PI

True. However, the A2 is only a dollar or two more.
The benefit is, when you're using a laptop that accepts the A2 Sandisk cardreader.
It will dd image at ~70MB/s instead of ~7MB/s on the A1.

Pi zero W external connection questions

it's connected through a router via WiFi, and to an external hard drive via USB.

And how fast can the pi upload files? Fast enough to stream 4k video's, if my network supports it?

I really would recommend Sandisk A1 or A2 microSD cards, they last longer, and run much faster in the Pi. This is nothing to do with redundancy. But anyway; A1 yes, A2 no.

I really would recommend Sandisk A1 or A2 microSD cards, they last longer, and run much faster in the Pi. A second option, try to boot from USB instead (SSD). The Pi doesn't really have a BIOS that can detect if an SD card went bad or not. So once it is corrupted, the pi won't boot, or be able to lo...

Floppy/Pata cables are used to transmit signals at 133Mhz or less. The GPIO pins mainly just transmit voltages (on-off at slow speeds), with very few pins actually used for data.
