Let's get one of these going.
This is a clock I'm planning on building soon. at each point in the grid there will be an led across anode and cathode, so that one LED will light up at a time to indicate seconds. The wire on the left then goes off to a repeat unit of this to show minutes, which then goes on to show hours etc. Just need some advice on whether this thing will function or not. I'll be using a 5v power supply I have lying around.
All the EEs left Sup Forums. This board is for GPUs and smartphones.

isis recruiter, pls go
First time back here for a while, migrated to /fit/, has it really gotten that bad?
You know what happens when Q8 on the left 4020 goes high, infidel?
Why is everything shorted together?
Thats just to save me placing 60 LEDs in the software. The wires will be separate and bridged by the LEDs.
display will be in binary. hope you can read binary. plus when it displays binary numbers that have more than one bit active, it'll put a big load on the u1 and probably burn out. and a 555 isn't very accurate. use a crystal oscillator and divide that down to get 1hz.
Does your software have a simulator? It might be worth placing them to test the circuit.
>First time back here for a while, migrated to /fit/, has it really gotten that bad?
Go look at the catalog, you tell me. is where the actual EE's hang out now.

This, U1 is probably not intended to have high fan-out. Consider buffering the output of Q12.
That's a pretty shit way to explain busing user, are you sure you should be starting an EE thread..?
to make it sequential (probably what you want) use 2 cd4017 chips.
Uhh, you realise that's a binary clock right?
> EE
Yeah, I just used the wrong chip in the schematic. I will be using 4017
I've seen you butthurt about this in no less than 3 seperate threads
>wrong chip in the schematic
and yet you wired it up as if they are 4020.
Yes, and I remain butthurt that the 8-bit compute threads, vintage electronic and hobbyist threads have been taken over by consumerist shillfagging of the highest magnitude. Search your feelings. You know it to be true.
They wire up pretty much the same
That diagram is like non-selfdocumenting code without comments
don't forget the keyboards, headphones and watchs
>They wire up pretty much the same
lol. your undies is showing.
I don't see an awful lot of difference outside of the clock out and clock inhibit pins
technology means consumer electronics to 90% of the internet, if you don't like it go to another board
integrated circuits are the cancer of electronic engineering. it is akin to being a lazy hip using shitton of libraries.
What's the point of drawing a circuit if you don't draw it correctly.
- You are using Q0-12 on U1 in your original image, the 4017 pictured has only a Q0-9 and CO.
- Clock input is inverted between the two
- The pins are assigned completely differently
- Have you checked for functional differences in the datasheets?
