Neopixel Ring Clock
Another graphical clock, where the hour hand is represented by red, minutes by green, and seconds by blue. Here it's 2:40 and about 20 seconds.
How it's made: Arduino, Maxim DS3231 real-time clock, 60-Neopixel ring in a shadow box behind translucent white acrylic and diffusers. Photocell dims display at night, can change color scheme at will, switch for Daylight Saving Time. Concept by Andy Doro.
