Handmade, unique Nixie tube clock - the "Nixie Nexus." This clock is made from a beautiful, solid wood blank made of curly red oak and black walnut, and has a rear cover made of solid black walnut. The photos shown are of the exact clock for sale. Each clock we make is unique in the specific natural grain and patterning present in the wood itself and laser serialized - this particular clock is DobsonCOdesign Nixie Nexus serial number 0012.

The case and the circuit board inside of the clock were both designed and assembled in Colorado. Features:

1. It has a temperature-compensated RTC (real time clock) circuit for the best possible accuracy. It gains or loses a maximum of about 1.2 seconds per week.
2. There's individually-controlled RGB lighting under each tube - there are 18 different dynamic color changing modes available.
3. There are 29 different animation modes available to cycle the nixie digits and show the time changing. Many of them are 3-dimensional and you can watch the transitions taking place spatially inside of the tubes. See the video for an example. The speed of these animations is also adjustable, and many of the modes have completely different looks at different speeds.
4. The LED brightness is adjustable, and there is also an auto-adjustment sensor that detects ambient light to dim them automatically if desired. This is great for a bedroom where you'd like for the clock to dim itself at night when you're trying to sleep.
5. The sleek, modern design uses no buttons whatsoever to clutter the appearance - all control and adjustments are done using a custom remote control, also designed and assembled in Colorado.
6. There is an optional temperature display mode.
7. A supercapacitor can power the RTC circuit for a couple of days without external power, so the clock does not rely on batteries to remember the time in the event of a power outage.
8. Settings can be either locked or allowed to 'drift' which will slowly and randomly change all of the different modes over time. This allows you to see many different lighting and animation combinations organically to keep things fresh.
9. This clock was designed from the ground up to show off the nixie tubes, allowing them to protrude and for their entire internal structure to be visible. Almost every design decision was driven by the desire to preserve these beautiful devices so they can be enjoyed for as long as possible.
10. Most Nixie clocks on the market use multiplexing for the tubes themselves and for the LEDs to reduce cost. This method looks fine to the human eye, but sometimes these clocks can badly flicker on camera. That is never a problem with this design - each LED has a dedicated channel and each Nixie tube digit is driven with a constant current dedicated line.
11. In the event that any Nixie tube does wear out, the tubes are socketed and can be replaced easily, without any tools.

All of the Nixie tubes used in our clocks are NOS (new old stock) IN-12 Nixie tubes which have never been used. These IN-12 tubes are one of the later and most reliable Soviet designs - they have much better lifetimes than some of the other earlier designs like the IN-1 or IN-4 tubes that many other Nixie clocks are based on. They also have a very unique 'feature' in that the number 5 digit is just a number 2 digit placed upside down. This was done to reduce manufacturing cost, but it also ends up giving the clock a very unique look that we really enjoy.

DobsonCOdesign is a small family business. We designed our first Nixie clock in 2012, and we just can't stop making them. This most recent revision of the design, the "Nixie Nexus" is the product of many updates and improvements over the years. We're new on Etsy but we've been at this for a long time.

If this particular clock design doesn't quite suit you, look at our other listings and check back from time to time to find one that does. We're making new clocks from time to time in different styles with different woods and patterns. Unlike some other shops where you'll get a clock that looks something like what's pictured, all of our listings show you the EXACT unique clock that you'll be receiving so you can be confident that it's exactly the one you want.
