Re: RPi 3B+ Heat/CPU related improvements.

If anyone is interested in how the pi looks without the metal spreader this guy removed it:

Looks like the heat transfer area is actually quite small.

Re: Raspberry Pi 3 B+ vs. Desktop

I deleted Firefox on the second day to be honest. If I remember correctly Open Street Map was the last nail to the coffin. Most annoying thing was FF used to freeze for ages and the only thing I could do was to unplug the power. I also could not log in to some websites and had to do it from my mobil...

One has to use Chromium as your browser.
Huh?
Others are slow, limited in capabilities and crash/freeze often. I find Chromium to be the fastest one with the least amount of websites not working.
Firefox is my favourite but I could not make it work in a reliable manner.

Re: Raspberry Pi 3 B+ vs. Desktop

I have been using my PI3B as a desktop for 3 months and it is doable but not pleasant. One has to use Chromium as your browser. It is not possible to watch videos in the browser in HD and there is a limit of 5-6 tabs at one time. Built in audio is terrible as well - a lot of background noise. I do n...

Re: Aluminium Heatsink vs Copper Heatsink vs Copper Heatsink with Fan

There is not much difference between copper and aluminium but huge increase in cooling efficiency if you fit a fan - especially if your rapsberry will be cooked inside a plastic case. You can also get a ceramic heatsink but I do not know how much worse are they compared to metal one. Good thing abou...

Re: RPi 3B+ Heat/CPU related improvements.

Seems like a lot of people are interested in this issue. @rpiMike Thank you for the link - very informative. @mahjongg the main trick is that they have flipped the chip (SoC) upside down, the back of the chip is completely flat and can make excellent thermal contact with the heat spreader that is mo...

RPi 3B+ Heat/CPU related improvements.

Hello. From the blog post I assume that the CPU speed boost is only the effect of better thermal management. This raises a few questions: 1. How does the heat spreader work? Is it only a metal plate put on top of the chip casing or is there a better thermal connection with the cores themselves? Will...

HDD partitioning for Raspbian installation.

Hello I am trying to set up pi to boot Raspbian from HDD. The problem is that I have a partition already on the disk with data that I need (and a lot of it). I was thinking of making a swap partition 1GB at the beginning of the HDD then another one after it 16GB for Raspbian (I use GParted). My unde...

Re: PI3 External HDD problem - password protected drive [solved]

Worked perfectly fine. I have been also able to remove the protection with sudo hdparm --security-disable knownpassword /dev/sda As you said it says everywhere that it is: DANGEROUS to experiment with, and might not work with every kernel. USE AT YOUR OWN RISK. Thank you very much for help. It is hi...

Re: PI3 External HDD problem - password protected drive

Ok I think I know what the problem is - I set up a password for this HDD (which I fortunately still remember). Is it possible to use this disk with PI?
I do not have access to any other computer so removing the password by plugging it in to one is not possible.

The only other device plugged in is a keyboard/mouse usb dongle and HDMI. I use the official pi power adaptor. HDD spins and both it and PI have constant power light and key...
