Re: learn Phython

Trial and error will be your best friend while coding anything in Python! If you can determine why a glitch is happening, it makes development go a lot easier. Make sure you are patient and willing to pay attention to how every line works together to make your code function properly.

Re: Raspberry Pi 4B Overclocking CPU

You could probably run over_voltage of 2 for both 1800 CPU and even 600 GPU. Every RPI 4 I have tried thus far as succeeded at doing so. Less over voltage will reduce your total heat. I’ll take it down to 3.5 and see how it does there before I step it down any further. I went with 4.5 to be on the ...

Looking at one part of the project "transmit all audio and video output information from the 4B to one 3B+" So the 4B gets (say) a video (with sound) file from the hard disc and sends that file to the 3B+ which then plays it over HDMI ? That sounds fairly straightforward or am I missing something? ...
