How difficult would it be to glue an arduino (or similar) to an ordinary wall clock to have it sync time via the Internet? Preferably PoE but I'd take WIFI too.
>>
Not hard if you buy 8000 Arduinos from Qualcomm
>>
>>107480311
Already a thing. Don't try to reinvent the wheel.

the hard part is the mechanical aspect. minute and hour are important, more so than second, so you need to cram 2 absolute position encoders in here.
>>
>>107480311
Depends on the mechanism of the clock.
You'd have to monitor ticks and know a pre-set time to determine what is currently being displayed. Then you'd have to adjust by "stopping" ticks or quickening ticks. You'd also have to somehow interfere or override the existing circuitry.
Simply sending a current through the copper coil (of appropriate polarity) without the devices battery installed should be enough to trigger a tick but not sure about efficiency so I'd disconnect the coil from the rest of it.

>Depends on the mechanism of the clock.
I'm talking about the ticking rather than continuous movement ones though those are both superior and do actually have ticks, perhaps on the order of 100s or 1000s/second.

I used to coordinate the second display by plugging the battery on the exact second.
>>
>>107480311
You can already buy clocks that have a radio receiver in them that listen to wwv time transmitters

I would love to have some kind of Amazon link where you can buy a programmable PoE wall clock for under $100.
>>
>>107480457
what a good boy
>>
>>107480457
As I said, already a thing, but not for $100.

Even chinks have them just an example: https://www.aliexpress.com/item/1005009121837114.html

Have fun tranny clockfag.
>>
>>107480653
>but not for $100
So you recommend buying a $250 wall clock instead of buying a $50 kit and making one yourself?
>>
>>107480663
If you are a poorfag you can always set the time manually. You just need to get up and stop stuffing your face with burgers Amerifat.

I told you already that you are pretty much reinventing the wheel. https://img.website.xin/contents/sitefiles3603/18019079/images/11322066.jpg

A fucking clock is a buy it for life item.
inb4 your janky DIY one shits the bed.

You are utterly retarded.

If you have to ask 4chan then it's going to be next to impossible for you. Cheap Chinese landfill products tend to not be designed for tinkering.

Pretty easy with stepper motor. Just mark 12:00:00 as a step 0, then 43200 steps will be another 12 hours. You can rotate hands to exact position by this. Then repeat infinite.

You are a poorfag if you are using keywords like "waste" in your sentences.

GPS is better for a clock as it's immune to Cloudflare crashing the internet
>>
>>107480775
The gears and magnet are already calibrate for that. No stepper motor needed. Just hook up the Arduino to detect voltages/current used, then replicate after detaching the circuitry.
>>
>>107480835
>keywords like "waste"
Go back pajeet.
Yes, it's waste. Not a cure for cancer. Sorry you had to find out this way.
>>
>>107480842
Did you build that?
Cool project.
>>
>>107480809
It would be awesome to do this with a sweeping (smooth) second-hand clock.
>>
>>107480835
You are a waste of air. Does that count?

>>107480311
.... just use an ESP32 to sync googles time api? Then use some screen to display that..?

you can buy off the shelf shit like that but circuits that control electric stepper motors arent that complicated you get one in most arduino 'project kits'

My router can be a time server and I wanted to add a gps module so it's rather accurate but I didn't feel like mounting an antenna somewhere, also it (and my PC) didn't support the tcp timestamps thing for super accuracy
>>
Or just catch the broadcasting signal with a simple circuit?
>>
It feels like such a complete waste to include radio/wifi, an extra motor and a system to wind the clock by exactly an hour that will literally be used only twice a year
Most consumer clocks aren't even accurate enough to not need any manual correction after a year. Analog clocks doubly so
>>
>>107480775
Stepper motor is complete overkill. You’d get better results with a cheap hobby servo, at least with those you don’t need to figure out a system for seeking to zero.

>he doesn't know
lmao

>>107484953
Just replace the 32khz crystal with your own signal and generate much higher frequency to set the time.

>How difficult would it be to
Oh boy oh boy. I will reply in parts
>glue an arduino (or similar) to an ordinary wall clock
Not difficult at all. I do this kind of thing all the time. You simply apply the glue to the things and press them together for a while.
>to have it sync time via the Internet?
Very difficult. I have no idea how to do this.
>>
>>107480311
They make them now that sync off the time coding in a gps signal
Or use a regular battery powered clock that loses maybe a minute a month at worst.
