Hello,

Also check the crystal connections.

Chris;
You have eagle eyes!! Good catch.
The unconnected pin 8 is the 4060’s ground return. Of course it can’t work.

 

You have eagle eyes!!

I am actually severely nearsighted. But if I take my glasses off, I can focus on things just an inch or two from my face. It's like having microscope vision, and it comes in handy!

 

thanks for the notice. I connected it and still the same, but in the two displays that are for the seconds incremented by one, it became 01

The 4060's pin 16 isn't connected to +5V either. Check all the connections to that ic.

Also, I've noticed that on the bottom row, the fourth from the left ic has no V+ connection on pin 16, and the second from right ic has no 0V connection on pin 8!

 

thank you guys for roasting me

 

here it is now

 

I did some changes. I wired two positive and negative wires on the left as you can see and the hours and minutes lit up but still, nothing is moving. i think i am getting close

You still have not added the 2 wires I mentioned in #26. Should the red wire in pin 7 of the second from right bottom ic not be in pin 8?

I saw all the stupid things I have done and I did some changes, the incrementation works but manually but only on the seconds. I can increment until 36 and then the counter resets. it doesn't increment on its own as a normal clock though.also, there are still some segments that are not working

 

The left side of the crystal is connected only to a capacitor. It probably needs a wire to pin 11 of the 4060. I think your resistors are swapped too. The 470K should go across pin 10 & 11. The green one (100 ohm?) goes in series with the crystal.

done it and still...nothing changed

Sorry, I edited my post. Did you see the part about the resistors? Electronic circuits are not very tolerant of wrongly connected or missing wires.

yeaaaa i seee realyy

you mean swap the two , right?

Don't swap the resistors! Put the wire in, but leave the 470k resistor in as it was originally. Check that the green resistor is the 10M ohm value, as per the original circuit that you copied. It biases the internal circuitry into its linear region! Too low a value will stop any chance of oscillation.

i have the wrong resistance, the 10M one is not 10M, but I am confused because one of the times I rewired it, it oscillated but not right, the minutes and seconds were working but at higher rates obviously, but couldn't increment manually.



can you please illustrate more how I should connect the two resistors?

 

Here's the

Oh, OK. From the picture, the green one looked to me like a low value. I figured that should go in series with the crystal, and the 470K was about right for the other one. 470K and 10M are much higher values than the example circuit I found. So what is the green resistor then in the TS' circuit? I'm sure that 100 ohms across there would not work.

I was going by the original circuit in post #8, which is also the same as that in the Nat Semi datasheet (although values slightly different.)
I'm also a little suspicious that the two 22pf capacitors might not be in fact what they should be: they look like high value ones to me?
If they are correct, have you tried a different crystal, the current one may be bad?
