    this is the circuit sir , but i need the schematic of this for soft copy purposes. 12213878_528170954004906_603246561_o.jpg 12182731_528168617338473_3913752097699522608_o.jpg

    Hi Genrick,
    There are loads of 'hits' for this timer. Mostly Philippine.
    You could spend an hour and draw your own schematic from the board itself!
    What are you trying to do with it?

    Here is the data sheet of the uC
    sm8952AC25PP

    "soft copy"? - the IC has "Code protection function".
    If enabled you won't be able to do that...

    Indeed it is.
    Time and timing is a fascinating area.

    Here is another for you: attoSec record ,
    not quite in the realm of us White Rabbits
    dealing with switching mechanical relays ...o_O

    What does it do? It should be easy do duplicate it with any microcontroller. It looks like it drives 2 relays through 2 opto-isolators.

    That's super good news! It means that sometime next year the Chinese will be selling 12 Attosecond/Div scopes for only $19.99,... and free shipping too! :p

    Connect it to *what*? If you don't provide any information we can work with, how can you expect an answer?

    What power sources do you have to run the device?

    What do you want to connect to the relays?

    What kind of signals do you have to control the timer?
