重有要多謝hippofather兄上次指點換display就可以。淘幾個7seg成本都唔使20蚊。

good job but I still do not suggest to use IC socket.

I may suggest to search the 7 segment unit in military grade (wider/higher operating  temperature range), then the MTBF for such 7 seg. unit is hoped to be extended.

Can you share us the time duration concerning to your 7 seg display unit can stand before any segments fail again later?
Had you used the "防熱膠紙"?  I thought that there is no big use as the 7 segments unit may still fail with similar time duration.
Moreover what will be the result if you add a down jacket on your body while you have a high fever?

    How much for the total shipping charge included?  much higher than the cost of 7 segment units?

人仔1.5一粒。買左4粒。運費5蚊到集運倉。因為有買其他野,所以成本加運費真係唔使20蚊。用socket最大好處係唔使再焊,省時又唔怕多次焊而出事。就算真係燒死哂4粒再買軍用級一樣就咁插落去。

8月用到似家。粒野暫時冇事。LED技術已經好成熟,我懷疑係原廠果批LED質量出問題。如果我果粒死左就上黎報告一下
