自制酷炫的新年燈籠

新年了，燈籠是非常有代表性的新年物件。紅紅火火的燈籠，既有美好的寓意，也是點綴新年的裝飾，還有實用的照明功效。作為DIY愛好者，必須自己做一個。

大概思路：使用ws2812b幻彩燈帶，配合亞克力闆，闆上刻上各種祝福語，投射出炫麗效果來；框架采用3D打印；控制闆使用esp01s，（配合直插led模塊），連接wifi使用BLINKER進行手機遠程控制；頂部300減速電機（5轉/分）使燈籠旋轉；3節5号電池供電。

材料與成本：整體還是比較便宜，esp01s，6元；RGB模塊，5元；減速電機、亞克力和3d打印材料都是幾塊錢。最貴的卻是電池，為了堅持長一點的時間，用的比較好的1.5恒壓充電電池，二十塊左右一顆，幾個燈籠電池花了一百多。三顆電池能堅持近二十個小時，幾塊錢的比較好的一次性堿性電池，時間差不多，但是每天都得換電池。
