Arduino LED filament clock

This is a home brew 56 Volt LED filament clock, I have tryed to replicate the nixie tube look. I have used a arduino with a RTC a ebay modified buck converter XL6009. The driver is MPSA42 and MPSA92 transistors. The washers in front are used for nav buttoms (adjust of time and show temperatur) I guess it could be called a little cyperpunk design. The update rate for the display are 4mS * 4 =16mS it's steady when looking at it but it flicker on camera.
