Re: RPI 4 USB-C supply

I don't understand why some people use 3rd party chargers when RPF/RPT (always get them mixed up) provide reasonably cheap power supplies which do as it says on the tin and are supported. I've, hold on... 6 Pi's running here (2 0w's 2 3B+'s & 2 4B4's) all using official PSU's and the only time I've...

Re: Access to GPIO connector in a Flirc Case

I've run into this same issue. I know a fresh install is best practice, but I would really like to preserve that data and transfer the SD card to an RP4. Is this possible? What data do you want to keep? What things do want to carry over that can't be simply added back later? I booted the Pi with an...

Why did they decide to do this? its severely debilitating. People coming from windows will not understand having to adjust the size of their swap file. Why do you want to use a swap file? Using it will cause excessive writes to the SD Card. Since reads & writes to the SD Card is much slower than RA...

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...
