[Mure] composed in to let us understand he has put the completing touches on the second iteration of his warm Tube Nixie clock. We featured his original development right here last year, as well as while lots of things stay the same, he has still discovered a few things that he was able to enhance on.

The very first significant function is the new genuine time clock. instead of utilizing a discrete crystal to keep time as well as a temperature sensor for compensation, he has opted to utilize a DS3231 RTC IC. It is far a lot more precise than the crystal, as well as it features a built-in temperature sensor as well. The alarm performance has been simplified too, moving the controls into firmware rather than having to utilize a moving switch to do so.

With the mainboard redesign, it would have been simple to leave behind the nixie “shields” he produced for his very first clock, however with a focus on interoperability, he selected to make this clock completely compatible with version one’s shields as well as vice versa.

While the modifications aren’t groundbreaking, it’s great to see a job such as this go through continued refinements. If you want to develop a clone of this clock, [Mure] has made sure that all of the schematics as well as source code are offered on his site.
