making a digital clock

[BTL-A4]

I'd like to make a digital clock. I want to use something like these 7-digit displays hooked up to some sort of clock module that is battery-powered. I would mount this behind a plate with openings for the numbers to be seen, or maybe in a box.

This is just for reference. I'm not sure what I'm looking for. I can find clock kits, but I want something that has separate number displays so I can space them farther apart. I also want a battery-powered time module (I'm not sure that's the right name) that I can run wires from to the display.

Would this work for a module? Here's the link:


I'm out of my depth here, but would like to try making this. Any help/tips/links would be appreciated.

Thanks!

Be sure to make a second 'clock' for the president, he likes those.

No experience but I think you are looking for these things.

Arduino 7 Segment Display Clock by Multiplexing Four 7 Segment Displays

This tutorial is about making a Digital clock by multiplexing four- 7 segment displays using Arduino UNO and displaying the time in HH:MM format.

circuitdigest.com

This guy make one with ESP32s and use NTP instead of RTC..

All interesting, no exp or strong enough interest to part the time from other interest.

You need more than the clock. Lay this out in a function block diagram and the clock chip is only part of it.
You need the power supply, clock chip, seven segment led driver, led segments, and control switches. It can be done and is around us all day.
Building one takes some work and study.
That clock chip oscillates at 32 KHz. That needs to be broken down through a decade counter to the required speed. The clock chip shown uses a I2C bus for communication. You will need to supply those components.
Plus all the wiring! Resistors, capacitors, inductors will be needed too.
Have fun.

Like @RPH says. I think that module you found is a very accurate but not enough to drive the LEDs by itself.

I have always wanted one of the Nixie tube clocks.

ebay has 7 segment clock kits. Should be possible to adapt this with some wires to larger numerals:

This my favorite clock. It should be easy to build this and then run wires off the board to individual number displays. It runs off a power converter or batteries. The stock presentation is great for greeting party guests.

I love those as well, but dog the big ones are spendy. One day I will make one.

I like them looking very industrial, very steam punk.

Looked at the kit, for the forty bucks it looks like fun with the grandkids. I ordered one and will see how it goes.
Thanks for the information.
