LED Word Clock

 

Dr. D-Flo Loves LEDs

It was only a matter of time before Dr. D-Flo built another clock out of NeoPixel LEDs. He stumbled upon Adafruit's word clock project. While the concept was cool, Dr. D-Flo felt like the design lacked style. By nature a word clock is not practical, so it needs to look classy. Therefore, Dr. D-Flo decided to make his clock with an anodized aluminum face. He did not stop at one but ended up building 5 clocks!

  • Please note the BRD file has two through holes at every LED, but the G-Code does not. These through holes are meant for 0.1 uF capacitors because Adafruit recommends having a capacitor connecting 5V to ground before every LED to prevent signal distortion. However, due to the simplicity of the clock I found these unnecessary, but you can add them for extra security.
