这个是1年半前做的了，今天才想起来没发过，发上来。在http://bbs.mydigit.cn/read.php?tid=1445415 坛友的代码上适当改动，把6LED的增加到16LED，用贴片stc15w408as控制。

sop-20封装的单片机焊在转接板上

0603的LED两头焊漆包线

焊16个，并点亮，确定每个都能亮

准备microUSB

木塞上给microUSB开口

装入瓶中的效果

点亮

你这不能飞，我找找，见过油管有个老外做了个飞起来的,似乎是用zvc感应电的

yzice · 发表于 2023-8-23 20:02:25

手工牛批的要做个记号，有空了慢慢看看

m3132427 · 发表于 2023-8-23 20:29:28

感觉铜线用的有点粗

mhtlov · 发表于 2023-8-23 23:52:55

有规律点，好看

ccbw · 发表于 2023-8-24 02:44:07

不错。挺漂亮的

sweetrong · 发表于 2023-8-24 07:35:30

建议加一个震动电机，随机震动

syomen · 发表于 2023-8-24 08:50:46

谢谢分享！！

临风听雨 · 发表于 2023-8-24 08:56:24

LED有些绿了，黄绿色是不是好些

xixia001 · 发表于 2023-8-24 10:27:24

不错，挺好玩的。

哈哈~羡慕动手能力强的大佬。。。

happysea72 · 发表于 2023-8-24 11:16:33

这个萤火虫在全黑的环境里怎么看着有点渗人！

wmshizheng · 发表于 2023-8-24 12:03:11

挺漂亮的，软硬能手

dang · 发表于 2023-8-24 12:31:35

有创意，感觉漆包线确实有点粗...

天使之音 · 发表于 2023-8-24 13:24:08

估计夜晚效果更漂亮！

kgmx · 发表于 2023-8-24 14:33:52

效果不错，挺漂亮

benx · 发表于 2023-8-24 14:55:47

做的漂亮，有才

创意不错，可惜就是玩一两次就没啥新鲜感了
