Purple Lightning Divine Sword with Handheld Ultraviolet Disinfection Lamp

Overview

A handheld UV sterilization lamp for surface disinfection. It is relatively dangerous to use; please use with caution. While the project was successfully completed, many aspects are still imperfect. This is only provided for reference; please attempt to replicate it with caution. An introductory video is available on Bilibili.

ETA6002

Single-cell 18650 battery power management module based on ETA6002

The schematic diagram references a successfully verified project
simulating battery input and

output voltage .

It's evident that the chip can draw power directly from the battery without external power.
Without external power, the LED will blink (screenshot from video).

This open-source PCB layout references the official recommended layout.

Pi_Pico_Rx

Pi Pico RX

Pi Pico RX, original project address https://github.com/dawsonjon/PicoRX, has a simplified power supply circuit. The grounding area of the filter section is too large, making it difficult to solder with a soldering iron; a hot plate can be used if available.
