Eye-Catching DIY Laser Level: Turn a Laser Emitter & Battery into a Practical Tool Under $10!
Transcript
00:00谁能想到,只需先在盒盖精准开槽,以便将这个小开关嵌入槽内,再把它翻转过来,在里面打热溶胶固定。
00:08接着把盒子翻面,以便在盒子侧面开出一个孔洞,再往孔洞安装一个激光发射器,同样地利用热溶胶将其固定好。
00:17而激光、发射器与开关之间还需用电线焊接连通线路。
00:21然后掏出一块锂电池,先把接口的电线和电池的正极电线对齐,焊点处用烙铁头轻轻一趟,金属瞬间融合在一起,再迅速套上一截决圆管,把焊点严严实实包裹住,防止短路。
00:35随后,再把盒子盖子轻轻合上,用手压一压确保密封延实。
00:41到这里,一个成本不到十块钱的单点激光水平仪便制作好了,手残档看了都能抄作业。
