Many tutorials are based on the /etc/apt/source.list only.

But there are also other lists

/etc/apt/source.list.d/rasp.list

and

/etc/apt/source.list.d/deb-multimedia-list

I found the tutorial below, but the keyboard and mouse didn't work: https://www.raspberrypi.org/forums/viewtopic.php?t=42888 This other tutorial worked with Raspbian Buster: (To work, Raspbian must be configured to load the desktop. It will not work if left only on the console mode. Must be Raspbian...

Hello, I have not yet tested the TP4056 module with BMS, but I tested this module without BMS. I have some emergency LED luminaires, which supplied a few mA of charge to the battery, but this luminaire had no charge manager and was damaging the 18650 battery with overcharging. The luminaire supplies...

Hello, I've noticed that it can not consume current from the battery while it is charging, so the 1N5402 diode provide power to the MT3608 while the power supply is plugged into the AC power outlet. I noticed that there was an error in the zener description: 4V7 1/2W. I tested the MT3608 with only a...

Hello,

Has anyone tested the TP4056 module (with built-in BMS) + MP3608?

I'm thinking of testing this arrangement:

There are many ways to configure the wireless interface, but anyone who only uses the console knows that it is a bit bad to work with multiple commands to get the configuration of a network card. :idea: A script might help a little, someone may be interested in testing, so I'll leave attached here (...

In the past, SSH was enabled by default, so people using their Pi headless could easily update their SD card to a new image. Switching SSH on or off has always required the use of raspi-config or the Raspberry Pi Configuration application, but to access those, you need a screen and keyboard connect...

I've seen some idea to update the system clock from the GPS, but need an application that receives GPS data and send it to the NTP, then update the system clock.

Hello, I would like to post this program here for my future research. This program attempts to receive data from up to three NTP servers.

Hello guys, Yesterday I turned off the Raspbian normally, I expected to stay only the red LED lit, after some time I turned off the power. Today I had a bad experience!

If you disable LAN chip, the use of super capacitors can be viable: Disable LAN9512 The LAN9512 is the hardware device which controls Ethernet and USB ports. This chip consumes almost 200mA, and it will be very useful to disable it to save energy when I don't need USB or Ethernet. The LAN9512 datash...

I was thinking of doing something simpler, leveraging what is already commercially available.

I would like to do a layout with super capacitors only to safely shut down the Raspberry. For the case of missing local electricity network.

since it has no more to do with it, you could put it for sale, perhaps in the http://www.ebuy.com
