只要愿意用垃圾就有一辈子用不完的垃圾,果然是真的
在座各位都是垃圾怎么办😤😤
不必用药外壳烤一烤然后贴上去。
💡直接锡焊 solder 那个点就行了,3秒解决
難的是找到那個燈珠壞掉了
燈泡這樣改,省了幾毛錢,到時燒掉一間屋!
Haha but why??
因为造成更易发热
@@akie5476 哦,谢谢!
用锡片修电灯其他LED头更易坏
謝謝!
上个世纪,中国人很穷,才会这样做。如今中国人一天所创造的价值,有数百美元。再搞这些事,纯属浪费时间!
如果會找到那個燈珠壞掉了和焊下來,你話會不會直接焊條線上去?
如果不會找到那個燈珠壞掉了和焊下來,有药的外壳有什麼播用?
我相信這太陽能電筒沒有人會用得上🤣🤣
都是充電頭,為何一個充電頭不能充電,另一個充電頭反而能充電?索尼攝影機7.6V電池無法充電,電池如何激活呢?
拿給懂電子的朋友, 請他幫你處理.
@denkychang 買個新的,我是不是比你快?😂
一句話就搞定的事你為什麼老是廢話一堆拖機台?
👍
好神奇啊!但這安全嗎?
不安全,最起码要用电烙铁焊接联通
非常不安全阿,除了遙控的那個是可以的,剩下的那些都是暫時性的,只適用於手頭沒工具或者沒有備品,但要使用才會去這樣做。
原本的LED燈珠是有電阻的,用鋁箔連起來,相當於是短路。導致其它的燈珠承受更高的電壓。短時間用一下還行,但長期使用會有燈泡燒起來的風險。

@@motoc6147 This is not an issue because the controller will keep a constant current instead of voltage.
少说废话
鑽頭這樣用,沒多久就廢了吧
對,而且只能用在軟材料上面。
不光钻头废了,连要开孔的板子也废了,没法定位,根本不知道最后孔会开到哪里😂😂😂
这是胡来呀 !
钻机毁掉了 !
