How to make a multi-colored (RGB) flashlight lightbox

Hello, dear readers and homemade products!
Just a couple of decades ago, almost all flashlights were created on the basis of incandescent lamps, and they only dreamed of bright LEDs. The modern choice of LEDs and LED modules allows you to create amazing things by the standards of recent years.
In this article, the author of the YouTube channel “KJDOT” will tell you how to make a bright colored flashlight.

Manufacturing process.
So, this Li-Ion battery charge controller … This module has a built-in converter that outputs 5V with a current of up to 1200mA.
There are two connectors on the board – microUSB for connecting a charger, and a regular USB, which is a 5V output. A large connector is not required in this scheme, and the master unsolders it, after having bite into the fasteners with side cutters .
How to make a multi-colored (RGB) flashlight lightbox The board will be powered by a 2000 mAh lithium polymer battery. The battery power wires are soldered to the “B +” and “B-” contacts of the charge controller, respectively.

You need to remove the protective heat-shrinkable tube from it, leaving only the board.

Therefore, you should solder the battery to the entire circuit last.
As you can see, by connecting the LED strip to the controller, it already works.
How to make a multi-colored (RGB) flashlight lightbox From the controller you need to unsolder the standard connector to which the LED strip WS2812B is connected.
Four pieces of wires are soldered to the released contacts. It is better to take them in different colors so as not to be confused when connecting to the tape.

In the walls of the box, using an engraving machine , holes are prepared for buttons, and a micro-USB connector for charging the battery.

In such strips, each LED has its own chip, and can be controlled separately.
The tape is cut into strips of 5 LEDs. You need 6 such strips. The result will be a lamp with 30 “pixels”, each of which consumes about 50mA at full brightness in “white” color.
Without removing the protective film, the strips are glued to the radiator. The author decided to do this in order to reduce the likelihood of short circuits.
