README.mdRetro Clock
Nixie clock based on stm32f103 "BluePill"
Description
Its based on stm32f103 RTC peripheral. The nixie valves are driven with 74LS145 BCD to decimal decoder The time is outputed through the NIXIE as wel as through the smal I2C based OLED.
Operation
Long press 'Ok' putton to enter into edit mode. Then short press selects the digit to edit. 'Left' and 'Right' buttons increase/decrease the value. Long press 'Ok' again to confirm new time.

Questions
How big is the Nixie power PCB?
It measures 80.3 × 29.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie power use?
17 parts, built around the NE555P, BC547 and IRF740. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Nixie power KiCad files?
From the VersBinarii/retro-clock repository on GitHub, at the commit this page was made from: the board is schematics/nixie_power/nixie_power.kicad_pcb and its schematic schematics/nixie_clock/nixie_clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie power design in my own project?
Its repository states no licence, so its author keeps all rights: ask VersBinarii before reusing the design.
