I want to build big pixel clock. And I start with WS2812B Led and PixelIt Firmware. 

I used;

• 6m WS2812B led 
• 1 x wemos d1 mini
• 1000uF capacitor
• LDR GL5516 for auto light adjustment.

Next upgrade is temperature, humidity, pressure sensor and ds sound player.

** The print file is suitable for 180x180cm printers. The top cover file is only suitable for 250x250cm printers. If you need the file for 180x180cm printers, please ping me.
