请原谅洗头房风格的题图。刚刚完成神光同步灯带制作，趁热乎劲，把过程分享给大家。

这是一卷一米144灯珠的w2818裸灯带，售价26包邮。

灯带两头都有接线，输入的一头是SM公头，输出的一头是SM母头。

因为神光同步单件只能控制最多120灯珠，因此不得不从中间剪断。

这是两条SM转5v3PIN的线，和一条一分二线，每根售价3元左右一条。

居然失败了！

发现接主板上只有一条灯带点亮，另外一条没有任何反应。

如何拯救？

原来问题出在接线上，问了店家，SM母头仅仅是输出口，需要在对端接线，在B站上找来Up主的DIY视频，理清楚了接线顺序。

把输出线焊下来，3针与颜色的对应关系，3Pin上面带箭头标记的是5v线，中间是信号线，右侧是地线。

在焊接之前，加上一个热缩管，用于后面加固。

接上测试，太闪亮啦啦啦啦

上机箱，装饰，自带背胶。

后面的玩法就不用多说了，希望能帮上有同样需求的值友。
