About the author : Dalibor
I am working hard on a clocks for a contest called “When Prague Meets Shanghai” (more about contest here: WPMS). This is a first oportunity how to present working tubes in a real product.
The clock electronics is based on Arduino, uses precise DS3231 RTC and as a HV supply I used high end PSU from Yan Zeyuan.
So, I made two nixie tubes with 50mm numbers, they didn’t contain getter. Pressure in both tubes is 30torr, so the glow is slightly fuzzy, however I chose that pressure so that I would be able to achive more uniform glow at lower voltage and current. Striking voltage after aging process is around 150V, I use 170V supply with 20k current limiting resistor. Current is around 4.5ma, both tubes and PSU stay cool.
Visualization..
Tubes running at 4.5mA.

Wonderful!!!!
Unbelievable. They look better than their originals Z5680M. You are a master, Dalibor!
Parada! Akorat mi nejde do hlavy proc tam nemuzes ty anody pripojit normalka spodem. Jinak kdyby ti ta soutez vysla, tak to by byl naprosto luxus! Drzim place.
Hi, the anode is actually going through the bottom, the glass pipe on the back is empty.. ;-)
Incredible work! I can’t wait till these are available for purchase, they are beautiful!
Wow! Just Wow!
