LED Clock DCF77

LED Clock (DCF77)

A visualization for the DCF77 signal using 2 WS2812 / Neopixel LED Rings (60 and 24 LEDs). The DCF77 Signal is received via a Websocket Stream, buy you can adopt it to use a real DCF77 Receiver Module.

The intention is not to simple show the current time, but to show the single (bit) signals of the DCF77 signal.

3D Printed Parts

I printed the 3D Parts with PETG (white for the diffusor/shader), and whatever color you prefere for the case and the stands. I printed all parts with a 0.6mm Nozzle (@0.3mm Layer Height) - but also added a 0.4mm Version (= 2 Layers @0.2mm Layer Height) for 0.4mm Nozzles.

The Electronics-Box needs some support, the other parts are fine without any support.

Needed Parts

• 60 LED Ring (WS2812 / Neopixel)
• 24 LED Ring (WS2812 / Neopixel)
• ESP8266 (I used a Wemos D1 mini) or ESP32
• some cables to solder the LEDs and the Microcontroller together
• a little bit of Hot Glue to hold the LED Rings in place (the moulds are slightly larger)
