LED 驅動維修.

之前兩個post都係討論LED跟環保的關係,
今次講番DIY.

話說兩個驅動都係燒咗一粒連接火線既smd (R100),
今日去開華強買野,
走去檔口買兩粒R100試下維修,
點知最低消費50粒, 作罷,
跟住問老闆娘俾兩粒我做板,
佢搵左一輪, 冇R100,
就俾咗兩粒R200我. free of charge.

返到屋企即時換落去,
胆粗粗試著,
OK, 正常番晒.
不過暫時都唔敢用住.
clarify 咗以下問題至放心.

問題:
以R200 代替R100 有冇不良影響?

我都有去過華強買晶體管, 個老板話只批發唔散賣, 準備走人去第二檔揾喇, 點知佢主動咁俾咗兩粒我...

所以我鐘意上去買嘢就係咁, 唔係話貪小便宜, 係話有人情味啫...

Same experience for me there, last time I  found one shop displayed the VIPer IC I needed and asked for the price.  The shop quoted me the price for 1000 pcs.  Actually I needed only 1 and I turned away.  At that time, the shopkeeper gave me the display unit for free...
