    Well, does anyone here have any experience dealing with power and meter? I'd searched on the web but so sad I cant find any suggested or proposed simple kilowatt circuit for me to implement and modify.

    I just manage to find the one similar to what I need.

    However, the current transformer is still a problem for me. For the meter, I still need to carry the data out for further process.
    What I hope is, anyone can guide me through for a simple meter that measure power over time, like kill-a-watt do (Because it is hard to know which pins being used).

    Thanks

    Erm... thanks for your reply. But I think I will make these part easier. I think I just use multimeter instead. However the output that fed into the LCD might hard to get as well.
