Minimalist Master Sword [USB-A]

Overview

This project originates from (under editing) the NE555 Breathing Light - Master's Sword - JLCPCB EDA Open Source Hardware Platform (oshwhub.com).
The base has been removed, and the blade has been modified to use a USB-A interface, allowing direct connection to a computer or hub.
The minimalist version requires only a 50-ohm surface-mount resistor and a 68mm ceramic LED strip, providing constant illumination, and the PCB components unrelated to the blade can be perfectly hidden.

Borrowing from the USB plug LED - JLCPCB EDA Open Source Hardware Platform (oshwhub.com), the PCB is directly used as the USB-A port, eliminating the need for soldering male connectors; simply add solder to the back pads to increase thickness.
There is also a breathing version using a 555 timer, also with a USB-A interface.
