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.
