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 /g/. This board is for GPUs and smartphones.

First time back here for a while, migrated to /fit/, has it really gotten that bad?
>>55553248
You know what happens when Q8 on the left 4020 goes high, infidel?
Why is everything shorted together?
>>55553326
Thats just to save me placing 60 LEDs in the software. The wires will be separate and bridged by the LEDs.
>>55553222
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.

Go look at the catalog, you tell me. >>>/diy/ 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.
>>55553353
That's a pretty shit way to explain busing anon, are you sure you should be starting an EE thread..?
to make it sequential (probably what you want) use 2 cd4017 chips.
>>55553222
Uhh, you realise that's a binary clock right?
> EE
>>55554130
Yeah, I just used the wrong chip in the schematic. I will be using 4017
>>55554147
I've seen you butthurt about this in no less than 3 seperate threads
>>55554206
>wrong chip in the schematic
and yet you wired it up as if they are 4020.
>>55554214
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.
>>55554237
They wire up pretty much the same
>>55553222
That diagram is like non-selfdocumenting code without comments
>>55553235
don't forget the keyboards, headphones and watchs
>>55554272
>They wire up pretty much the same
lol. your undies is showing.
>>55554440
I don't see an awful lot of difference outside of the clock out and clock inhibit pins
>>55554244
technology means consumer electronics to 90% of the internet, if you don't like it go to another board
>>55553222
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?

Bruh.
