This is the central documentation page for Omnixie® Tube Clock.
Once the auto-on-off feature is enabled, the clock will check whether the current time falls between the “sleep” time when the minute changes. If so, it will turn itself off to follow the auto-on-off rule. The auto-on-off feature overrides the manual on/off.
When in doubt, first try to disable the auto-on-off feature before proceeding with any troubleshooting.
If you need to reset the clock while preserving the WiFi settings, use code 4648 instead of 9434.
Some of you may have noticed the humming noise of Omnixie/Omnixie Plus nixie clocks, or other nixie clocks with adjustable brightness feature, especially during nighttimes when the clock is located in your bedroom. Although some may think it is barely noticeable, others can get annoyed by the noise, as hearing capability differs among people. This article discusses the principles and provides two solutions to minimize the humming noise.
Our Omnixie and Omnixie Plus clocks allow users to adjust the brightness of the tubes. This is achieved using PWM (Pulse Width Modulation), which is a common way to control dimming of LEDs, or the direction of a servo. During PWM, the digital signal is turned on and off repeatedly at a high frequency (thousands Hz). By manipulating the percentage of the ON time vs OFF time, named “duty cycle”, one can achieve analog-equivalent voltages on the tubes, therefore adjust their brightness. The side effect of PWM technique is the humming noise created by the rapidly switching of the voltages.
There are two ways to keep the humming to its minimal level. Both methods apply to all Omnixie and Omnixie Plus models, regardless of their tube types or enclosure materials (obviously).
After setting up the clocks with these two methods, the humming noise should be minimal.
6 types of tubes are supported.
The Omnixie clock supports 6 different types of Nixie tubes, as shown in the photo below.
Other than their various appearance, they also differ in term of the scarcity, as they were manufactured in 1970s to 1990s. All tubes are so-called “New Old Stock”. This consequently leads to their price difference. Simply put, the price is higher if they are more difficult to find these days.
Among them, IN-14 and IN-8-2 are the easiest to find on the market.
Surely you can.
We know that some of our customers have collection of Nixie tubes, so we offer the Omnixie clock base (with the colon tubes included) so that you can supply your own tubes to make it a complete clock. Other than the 6 tubes, everything else is included in the sale (colon tubes, remote, usb cable and power).
Omnixie models A, B, C and D share the exactly same clock base. In order to use different tubes, you need to buy the corresponding PCB adapter to fit the tubes to the base.
For example, if you own an Omnixie model A (IN-14 tube version), and you want to use IN-8-2 tubes instead, you can simply buy the IN-8-2 PCB adapters from us, and solder your IN-8-2 tubes to the adapters, before they can be plugged onto the clock. Remember to change the tube types after the tubes are changed, using the remote control, or the web interface. Details can be found in the Omnixie instruction manual.
Omnixie model E and F use unique socket types, therefore cannot use any other tube types than the ones they are designed.
You can update the firmware yourself if you feel comfortable.
The latest version is v1.3.7 as of July 6th, 2019.
What you’ll need for the update:
Connect these 4 holes to a USB-to-SERIAL adapter.
Unzip it to get the exe file. Follow the procedures shown in this YouTube link.
If everything goes well, this is what you should see this.
