  • Does old condos built in 1976 needs rain screen ?

    I recently went to view some old condos units in Greater Vancouver, Canada, which are more than 45 years old.

    whenever I raised the question: is the building already rainscreened?

    (as Canada BC  government regulation:: condos/apartments, new or old, all need rainscreen as from 2013. )

    most of the answers are NO, this building was not built in years of the Leaky Condo period... It is not necessary for doing rainscreening, we had new roof, new siding, new windows, re-piped.

    I am confused,  old condos built before 1976 are exempt from rainscreening??

    what is this wire for PSU +5vsb?

    My PSU had no +5vsb, then I made visual inspection, but had NOT found any components abnormal (No burnt, stain, burst, or discolour...) .

    I found this wire coming from behind 2 huge capacitors to the +5vsb small PCB. This wire just goes through a doughnut then going back. what is this wire -- it does connect to the small PCB?

    capacitor bank?

    my desktop PC is dead because 3 of the 10 capacitors beside CPU are burst/ bulging.

  • why dc motor is dead when windings overheated (insulation broke down?)?

    Even if one or tw0 of winding coils are overheated (shorted) , electric current is still going into all the winding coils.

    that is, other un-shorted coils should still good for turning the rotor???

    or can we say, even shorted one coil is still conducting the current??

    怎樣打開直流馬達機殼?

    9.6V 電鑽死了, 把電池直接接到馬達端子, 也不轉動,

    機殼上沒有螺絲 , 沒有扣環 , ((那兩個邊邊凹槽不是扣榫))

    只有四個空洞 , 其中兩個空洞內, 有兩片金屬,

    猜想; 這兩片金屬就是扣住機殼,

    問題; 這兩個洞內的金屬片, 應該向右轉? 還是向左轉? 才能打開機殼?
