💡 Basic Information The flashlight I propose to assemble is a versatile solution suitable for various situations: during blackouts, on hikes, while fishing, or simply for everyday household needs. Its compact size, autonomy, and Type-C charging capability make this device portable. The assembly cost is affordable, and ordering components during sales can save you even more.

⚙️ Components To build the flashlight, you will need the following parts: 2. COB LED Module: Provides bright illumination, dimensions 94x50 mm. 3. 18650 Battery Holder: Ensures secure placement of the battery. 4. 18650 Battery: Rechargeable power source. 5. TP4056 Charging Module: Includes protection against short circuits. 6. PWM Controller: For adjusting light brightness. 7. Battery Charge Indicator: Displays the battery charge level. 8. MT3608 Module: Boosts voltage to the required level. 9. Button: Used to turn the flashlight on and off. 10. Magnets, wires, heat shrink tubing: Additional elements for ease of assembly.

🧪 Operating Principle The 18650 battery is connected to the holder, which supplies power to the TP4056 charging module. This module manages battery charging and ensures safe operation. The output current then flows through a button, acting as a switch, and reaches the MT3608 step-up converter, which increases the voltage to the required level for the COB LED module.

For convenience, the battery charge indicator shows the charge level, while the PWM controller allows you to adjust the light brightness. All components are housed in a case that can either be self-made.
