    The series one, everyone say its going to be hot! Hence need huge heat sink.

    Actually, I thought going to SLT to buy the diode and other stuff.

    Actually, maybe next weekend, we meet up at SLT and do up the circuit? I have a battery-operated soldering iron.

    but not that hot till u can boil water
    the heat sink is not that HUGE either
    I think just try? no harm anyway. the most blow 1 IC chip. cheap one anyway
