自制酷炫的新年灯笼
新年了，灯笼是非常有代表性的新年物件。红红火火的灯笼，既有美好的寓意，也是点缀新年的装饰，还有实用的照明功效。作为DIY爱好者，必须自己做一个。
大概思路：使用ws2812b幻彩灯带，配合亚克力板，板上刻上各种祝福语，投射出炫丽效果来；框架采用3D打印；控制板使用esp01s，（配合直插led模块），连接wifi使用BLINKER进行手机远程控制；顶部300减速电机（5转/分）使灯笼旋转；3节5号电池供电。
材料与成本：整体还是比较便宜，esp01s，6元；RGB模块，5元；减速电机、亚克力和3d打印材料都是几块钱。最贵的却是电池，为了坚持长一点的时间，用的比较好的1.5恒压充电电池，二十块左右一颗，几个灯笼电池花了一百多。三颗电池能坚持近二十个小时，几块钱的比较好的一次性碱性电池，时间差不多，但是每天都得换电池。
