## What is Nixie Clocks?

Zen Nixie Clock is our first 6-tube clock designed using R|Z568M nixie tubes from our production. The case is designed in a minimalistic way, combining simple aluminum stand and a glass cover – just like a museum vitrine. Thanks to its simple shapes, the clock suits every interior – especially offices, living rooms...

Zen Nixie Clock features

Internet connection – the clock contains a wifi module and is designed to operate online. The time is automatically synchronized from network, so you don’t have to do it manually and there are no other devices necessary (no GPS modules, radio modules etc..). In case of power loss, the clock remembers all the settings and time will be synchronized automatically from internet.
Easy online settings – all settings of the Zen Nixie Clock can be controlled online from your user account on our website. No need to search for user guide anytime you want to make changes in settings!
Silent circuitry – the clock is absolutely silent, there is no audible noise produced by its electronic parts.
Direct driven design – nixie tubes are driven directly, this prolongs their lifetime. Common practice is to use multiplexed driving circuit (which is easier to manufacture and cheaper), but such a driving circuit shorten nixie tube lifetime.
Cathode poisoning prevention – the clock can periodically run a cathode poisoning prevention routine. This helps to keep all digits of all tubes in good condition.
Rotary knob – for offline users, there is a rotary knob on the back of the board. Using this knob, user can enter into settings menu and do the settings manually. This feature is still in development.
Online firmware update – the integrated wifi module makes online firmware updates possible. Whenever there is a new firmware update (new features, bug fixes), your clock can be updated remotely.
No blue spot – there are no blue spots in the tubes known from some other clocks (especially clocks built with IN-18 nixie tubes).
Colon tubes – the clock support our colon tubes (in development), they will match design of the nixie tubes (by base and internal structure).
RGB underlight – there are 8 RGB leds (WS2812B – “neopixels”) on the bottom of the board which make some cool effects possible. Purist customers who prefers nixie tube glow only can set the underlight off. This feature is in development!

### 2/5 — Bad idea updates

*2026-07-22*

First you remove the capability to change out of 24 hour time. Ok, I’ll deal with that. Now you make it so it doesn’t even rotate to landscape?? Really? Does this really help sell more of your physical clocks? Because I doubt it. This is without a doubt the best looking nixie clock app out there, but you keep killing it slowly with updates.

### 5/5 — Finally, a clock that works…

*2026-04-04*

Third time I’ve tried one of these cool steampunk style clocks that resemble old cathode ray tubes. So far so good. Used the nixie clock app to connect to WiFi and it was functioning properly within one minute of starting set up. Rainbow mode rocks as it mirrors my Alienware Area 51 gaming laptop. I’m very pleased.

### 2/5 — Not Satisfying.

*2023-10-26, version 0.13.1*

True nixies have different depths for the numerals. These are all in one plane.

### 4/5 — Would be amazing if this was a widget!

*2023-06-05*

Please make this in to a widget 🙏

### 4/5 — Add Improvement

*2023-03-28*

If “Cathode Cleaning Interval” is set to 1 minute, there should be an option (ON/OFF) to make it replace the normal “Digit Transition” on every minute change.  This would vastly increase the visualization, at least on the Puri 4.

Thanks!

### 5/5 — Nixie

*2023-03-09, version 0.12.7*

It’s the most satisfying thing to see

### 5/5 — Please please add a widget to this wonderful app

*2022-11-11*

This app is great, please please add widget to this app  I want to have it on on my iPad all the time, instead going back and forth to see. So asking if you could add widget to this awesome app. Thank you!

### 5/5 — Widgets

*2022-09-21*

Best nixie clock, please add widget to this wonderful nixie clock.

### 1/5 — Nixie app

*2022-03-13*

It’s a terrible app you can’t get it out of military time and help does not attempt to even address it

### 4/5 — 12 Hour Mode TvOS

*2021-11-12*

For the tvOS version the clock needs a 12h format. Please add it.
