For ages I have wanted to have a large scale LED digital clock for my room ever since I saw 4" 7-Segment modules. Decided to use addressable LEDs so I can have colour options and along with my 3D printer.

The display will be able to have different colours for the hours and minutes (fixed and various colour changing - one shown in video), the display will adjust with ambient light (so it isn’t a lighting the room at night!) and I want some form of DST setting to easily change without having to change the time. I did think of some form of automatic change but then it would need to change based on country. I want to have a button that turns DST on and off.

So far have printed the digits which are glueing together and the Arduino can now read the clock module and display the time. Need to print out the colon which also holds the electronics and buttons. Once that is done then I will get the firmware/software (which is the right term for an Arduino?! LOL) to be able to set the time and deal with the colour settings.

BTW ignore the hot spots in the video, IRL it is much much smoother!

Now about an esp8266 and fetching time and dst off the internet? :slight_smile:

@Thomas_Runge Nah that would be sensible in this day and age, who doesn’t like having to change their clock twice a year :wink: In all honesty it is because I have a number of ds1307’s laying around :smiley:

BTW the digits are about 11" tall :wink:

Excellent, looks really good. Nice large size too. What did you use for the white diffusion?
Please share again once finished.

What materials are you using for the backing and translucent front?

7

They are both PLA. The white front is only about 1mm thick which defuses the light okay but still allows enough through to be visible during the day.

Once I am done I’ll get it up online (although be kind with my programming it is all self taught and maybe not the best/most efficient way!)

It’s working and lighting up, that’s the most important part! Programming tweaks can come later if needed. :slight_smile:

9

That’s a very cool project! Love the PLA idea. Easy to print and make your own parts there.

Got the 4 digits up and running now. Just waiting for the 3D Printer to finish the central section where the controller and seperator colon. Once the display is glued together I can get the final programming sorted :smiley:

@Kelvin_Shirley Very cool. Could add a few numbers and have a Christmas Day countdown in the yard year round! :slight_smile:

@Kelvin_Shirley can you include the link to your Thingiverse post here and/or in your other post?
