Yes i know that´s a very nice adjustable circuit, but the only thing i don´t need is to push any switch, it has to be done perpetual, it has to reset itself every 2hr cycle, any way i will test every option and take the best situation that fit the needs, thanks for your attntion Sir.
Yes, that's what that circuit does.
No manual reset needed.

Sorry the 12 hr, post # 13, is suposed to be 2 hr; that is what the 4060 is setup for.
Modification shown increases reset time to about 6 sec.
Setting 2 hr with a 1 M pot, Rx, is trickey but gives a first approximation, ahter measuring pot replace with smaller value pot, say 20 k multi turn & pad remainder with standard values . Assume that 880 k is closestView attachment 80675 measured value & a 20 k pot. is available, then use 1/2 of pot value,10 k, add a 820 k & 51 k = 880 k. Other combinstions OK.
Surplus parts again-- R2 & C1 are not needed, bypass R2 & remove, remove C1.
Bernard i´m testing in the sim your circuit but of course it suppose to work 2hours cycle, what if i want to speed up to make a quick test and see if trigger fine? i´ve been playing around with the new configuration you gave me allrdy changing Rx values.

OK ok, never mind so far i tweaked everything and found the way so now i have signal in a shorter time just to check everything ahead w the 555 next, let you know, thx a lot.

Eliminate C1 or add 10 k, IC 1 reset to ground. There is a roundabout OR from IC1 Q14 & Q 12 to trigger IC2-2 ? Most R values seem a little low.

I´ve been testing all the outputs to learn how this ic works, i didn´t knew that it does the same cycle on and off, for now as i put everything togheter works fine i need to do a full time 2hr test and certify its operation and reset, till now in the lower case (shorter time trigger) it does what supposse to do so i´m pretty happy but need to test and check in deep, i´ll take you advice, thanks again Sir Bernard, let you know.

For what it is worth, I bought one of these very low cost timers from ebay: http://www.ebay.co.uk/itm/400788130469?var=670339068947. There are 3 different supply voltage types. I suspect that option 8 would be right for what you want except that you would have to reset the switch after 1999 cycles but that is a very long time (over 83 days) which, I assume, should be well past the normal incubation time for an egg. The big advantages are that they are ready built and have a 4 digit display for parameter settings.

Yes u´re right friend but not everybody has acces to that kind of stuff for many reasons, remember this WWW and you can be chatting with people around the world where the situation is diferent country to country, in my case i live in Venezuela and we don´t have easy and cheap acces to international currency like dollars or euro, and at the actual rate that is some expensive (inflation bro), so it is cheap to build by my self and in the proccess i learn something new wich is the most valuable asset, cheers and thx bro.

Hi Bernard i´m coming back after being bussy to finish this timer, listen i´ve been working in the config you suggest me, but probbably i'm doing something wrong, sometimes it trigg fine and then it just roundabout or something like that, can you help me? remember this is the 2Hr/6 sec relay controlled timer or adjustable anyway, here is the sim schemm so far.

R9 can be omitted from the transistor, also the reset pin is tied to ground on the drawing, that wont work, just connect it to pin 3 of the 555 timer.

But pin 3 in 555 is output to activate the relay and reset 4060, i tried that you say and doesn´t work, never activate the circuit, i does like a runaway.

So far the best config a could find, no roundabout, and always repeat the requested task at the time, litle sec fluctuation wich is ok for my case. Moving now to hardware mode.

Guys me here againg, listen i´m having some issues with the trigger integration, did u remember that i built the 555 timer under 6v and the 4060 on 12v? i´m having some issues with that everything works ok until 4060 trigg 555, it doens´t reset at all the 4060, and the 555 remain on after the desired time to trigg. i desired to take the power from the 12v rail feeding the 4060 to feed the 555 circuit via LM7885 wich is ok for the 6v 555 timer trigger, but at the end the reset 555 to 4060 does not work as an integrated system, in the simulator works fine but in the proto doen´t, what should i do? it is probbably somethin simple to fix but i tried some things with no result, if i run everything together in 6v i does work fine what can be happening? my mistake i now.

Why not operate both IC's from same Vdd? All prev. ckts show 9V, this is the first time that 12V has shown up.
yes but unfortunately the 9v power supply got damage and i have lot of 12v small supply, eventually i did test the 4060 timer over 12v and it works fine, my problem come when i tried to integrate the 555 timer i did desing in 6volt because of the relay too, and complete that apart from the 4060 system so now i´m in this new trouble, so crazy i don´t know what to do, after being complete everything almost this new issue got me by surprise, i still having a 555 apart as a spare so not a problem, my only concern is the relay cause i have a 6v one but i do have a lm7805 voltage regulator to drive the relay at the end. so far i preffer to remake all this in 12v because the relay and the 2 IC so i have enough to run everything ok.

so far as i toll u, i did test 4060 in 12v, runs fine, but when it trigger the 555 cause i did install the supply inside via lm7805 it turn on but gets on and doesn´t comply with the time desired to come off and reset the 4060.

I have this adaptation to resume what i did with the 555 but as i toll before i have no problem to remake everything so far the 4060 is simple to setup but my concern is the 555.
