HDD Persistence of Vision Clock!!

This is a quick project video on my Hard Disk Drive Persistence of Vision Clock V2.0 or HDD PoV Clock V2.0 for short.

I created this clock out of a 2.5″ Server HDD, 2 custom designed PCBs and a lot of patience. The processor used in this clock is an STM32F411RET 32bit ARM microcontroller. I’m using WS2812B LEDs (all LEDs have their data lines connected in parallel), a DS1307 RTC for time keeping and an ESP8266 WIFI module for future features.
