Is there a command line (bash) tool I can use to monitor the temp please?
Also, if you want to see the temperature there is a panel applet. The advantage is that the temperature is shown on the taskbar all the time.

Re: Temperature conversion

Hi. Is there a way that I can make my Pi 4 tell me the temp in f instead of c? While that would be nice, we should be grateful that it isn't given in Kelvin or Rankine. It would make no difference in complexity. It is only simple math. T°F = (T°C * 1.8) + 32.0 T°F = (TºR - 491.67) + 32.0 T°F = (T°K...

Re: Raspberry Pi 4 temperature

I'd say it was a regular case. Just a very well designed one. Looking at the one I have here, the LCD cable and camera cables have exits, and there is an available slot to get a GPIO ribbon cable out should you so wish. Indeed, there is a slot provided for a GPIO ribbon cable, but do you know of a ...

Re: Raspberry Pi 4 Thread - general discussion

I have not tried without the case but with the crap thermal pad supplied with the case it was 49-51°C idle and 78-80 with cpuburna53. After replacing it's now 46-47 idle and max 68 under load. I would probably see the same 51-55°C without anything and throttling under heavier load. I know the groun...

The 4GB part used in a RPi 4 is a Micron MT53D1024M32D4DT-053 and you can see the prices for it online. They probably have a much better price worked out with Micron due to the hi...

Nice result on the GPU memory increase. On my Pi4B1 I have a 1000MB swap file, Chromium seems to run better. What if you use some of that 4GB as swap, would that improve things? USB 3 swap?

Once a 64-bit version of Raspbian is developed both a 32-bit and 64-bit versions will have to be maintained for period of time. The same for sof...

Re: Raspberry Pi 4 RAM variants

Having more than 4GB RAM provides no value for most people since Raspbian is 32-bits. To go to a 64-bit version of Raspbian would break a lot of programs and drivers. Sure you could have a 32-bit mode so some 32-bit software would run in a 64-bit version of Raspbian but that would require a lot more...

That must be why Scratch 3.0 online with Chromium works now.

When I tried Scratch 3.0 online with my Pi 3B+ a few months ago it was so slow it was unusable. I guess I'll try my Pi 3B+ with Buster to see if Scratch 3.0 works any better.
