    Two standby modes: one that powers IR and CPU (which has it's on standby mode too but not shown), and another that powers clock and memory.

    The battery sends power to the clock and memory when prompted to turn on by the CPU. Though if I don't need the battery that's better. I just want the clock and flash to be standby mode 2, but rely on standby mode 1 to be powered.

    This one is to complicated to follow through 'word pictures'. I think we will need something more 'pictorial' in nature.

    A CPU can take of 'power modes' easily, but needs to have a standby power source - as you stated.

    The operating program will 'wake up' the processor at pre-determined intervals to check on the outside world conditions, then back to sleep

    What are you doing exactly? Would be easier to help you if we could not be so GENERIC in this process.

    Oooh, I see.

    Well I am in winter school and the first day in electronics class (I have no experience in this area) the professor was like "make the most efficient standby mode for this DVR" to the class and didn't give us anything but some schematics. I have no idea why he's doing this yet.

    So I need the clock and memory but only so that the system can remember to auto turn on when it's supposed to record. If it's not going to record ever then I'll have everything but the IR and necessary cpu functions that enable the system to turn ON again, OFF.

    I made a lot of concepts, but need help with it.

    first day in electronics class ???:eek: Geez !! this guy don't want much does he ??

    Hopefully I missed a boat somewhere, and you have some basic electricity / electronics in there somewhere.............

    I have to agree. Your FIRST DAY of class? Your teacher wants you to produce a DVR?

    Woah!

    This must be the first day of the 30th Semester.

    I cant do it, and I have been studying electronics for a week! ;)

    Well it has helped me learn what a resistor is by my own efforts instead of his lol.

    I don't he expects us to succeed at all, but I don't wanna lose =P.

    Oh.. So he tells you that the DVR is the FINAL project, and is teaching you little by little..

    Is that it?

    so u basically want a 1mW Power supply operated by mains

    Yup. Well it's winter school so he has to cover a lot of ground on a single day. It's a class to teach us the basics and I'm in it now actually :). Next week is the last week.

    Everything that he's taught so far I basically already know because of this 'project'. But it's just the basics until we get to the heavier math parts later this week (already learned the laws).

    That's most likely his plan.

    1mW to blow up my DVR you mean? :D

    That would be 1 MW not 1 mW.
    1 milli Watt is quite small.
    1 Mega Watt will do some work.

    Oh okay I see what you mean, thanks. That will be enough?

    Today I actually see what Kermit is saying even more now, so I'm gonna try to finish the concept today.

    Then I have to go back to the old schematics and show the prof why my system is more efficient than the one he gave me.
