16-seg word clock

[newxito]

85 hours of 3D printing
216 RGB LEDs
8 ATMega328p based display boards
1 ESP32 based controller board
1 I²C bus connector board
31.5" wide, 6.3" high

The clock is kind of useless, way too big... maybe I can nail this thing to a wall in the shop.

Now back to nixies, I have some ZM1350 waiting for a clock
This hobby is getting a little bit out of control :-)

Most excellent....well done!!

Now you just need to make it twice as large so I can hang one on my man cave wall....LOL!

Will you be sharing design files etc?

Truly excessive. Love it.

[Richard Scales]

That is most excellent. I am dwelling on word clocks at the moment and have some ideas though nothing quite as grand as this - very well done indeed.

Currently working on a ZM1350 smart-socket based project.

[Michail Wilson]

I want to print one!

Instead of 3D printing the diffusers, I might use diffuser material like Lee Zircon 810, 811, or 812. It’s easy to cut with a laser cutter, scissors, or a knife.

I am now on vacation but after that, if anyone is interested I can set the pcb projects on easyeda to public and provide the stl files.
John, thanks for your input, I agree, the 3D printed diffusers are far from perfect. If I make then 10" version, I will try the Lee Zircon filters.

[Jack Buechler]

Are there any diagrams - either mechanical or electronic?

It would be interesting to look at how you built and designed it all.

I don't have any documentation apart from the schematics of the PCBs. Building this kind of led projects is very easy these days. The SK6812 leds are great. You can interconnect hundreds of them and control them all with a single mc pin, and an easy to use library hides the programming complexity. Since I wanted to use a PCB anyway to properly solder the leds, I added some "intelligence" to the displays with an ATmega328p. All the displays are connected using the sda and scl pins and act as I2C slaves. The I2C addresses are defined by reading the voltage on a voltage divider using different resistors values. The ESP32 board is the master.

Greetings newxito and all Nixie-onians,

I'd be very interested in any documentation you're willing to share.
Fabulous ELWC!

All the best,
Sam
