    Hi crazycolour, welcome to AAC!

    All of those components should have markings on them telling you exactly what they are. Resistors have the colored stripes that denote their resistance (see http://www.allaboutcircuits.com/vol_5/chpt_2/1.html ), capacitors generally tell you exactly what their capacitance and voltage ratings are, and transistors have part numbers. Furthermore, I see a relay, some diodes, an LED, some potentiometers (variable resistors), and of course the 4060 ICs. All of them have numbers on them that should tell you what they are.

    Regards,
    Matt

    EDIT: Sorry, I didn't realize you were just going by the picture. I thought this was something you already had. Anyway, why not use a simple 555 timer? Much simpler and it uses fewer components:

    The values of R1, R2, and C1 determine the time delays. You can replace R2 with a potentiometer to adjust the timing manually. If you don't want it to turn on and off and back on again, then you can wire it up for monostable operation:

    That stays on for a time determined by R1 and C1 and then shuts off, and will not re-trigger until you tell it to (with a pushbutton, for example).

    All true, but the original device appears made to switch a 220V AC load with up to 3 hours of timing. Not quite the same thing.

    Yes Wayneh you are right. I want to switch on/off a 220v AC load a and timing between 2 minute to 2 hours.

    Thanks DerStrom8, but i want to know what is the capacitors capacitance & voltage rating (part number )and the diodes part number, what is the relay part number & so on.

    The timing circuit does the exact same thing. All you need to do is connect the relay to switch based on the output of the 555 timer, rather than the 4060. And 555 timers can time through hours. You just need a large capacitor and a high resistance.

    Well all diodes can be 1n4148. Capacitors all are for 25V. C1 = C2 = C3 = C4 = 1uF .... 47uF ;C5 = 680uF; C6 = 10uF
    but I'm just guessing.
    R1 = R3 = 470k;
    R2 = R4 = 5.1k
    R5 = 10K
    R6 = 5.1k
    R7 = 560
    R8 = 2.2k
    VR1 = VR2 = 500K
    Q1 = c9012
    relay?

    This might be helpful, as an alternative.

    J1, J2, and J3 are zero Ω resistors...just jumper wires.

    Is J1 supposed to be broken like that?

    I doubt it! Good catch. That would be the height of silly - a disconnected zero ohms resistor.

    Hello,

    The jumpers are there to select the timer range.
    You install either J1 or J2, see the schematic from the posted PDF:

    Hello,

    To me the difference between J1 and J2 is an other counter output.
    It is the selection between Q8 and Q14 of the counter:

    This will change the timing dramaticaly.
