Kinetic object clock with NeoPixel-Ring
A kinetic object that shows the time at two concentric NeoPixel-rings
A hardware and software project for a friend who loves clocks in all variants.
It has two concentric NeoPixel rings and some moving parts to form a kinetic object that can even display time in an old-fashioned "analog" way :-). Hours are displayed on the inner ring, minutes and seconds on the outer ring.
The electronics are located in the base of the object
Here you will find a short VIDEO of the object. and here a more detailed Blog-post https://peterneufeld.wordpress.com/2020/06/09/kinetic-object-clock-with-neopixel-ring/
An ESP8266 (Wemos D1 mini) controls 86 neopixel LEDs and a 3V mini motor to turn a wooden ring.
A second mini-motor permanently rotates the wooden gearwheel mechanism of a weekday calendar, but actually only to make it look like something more.. This is a nice laser cut model from UGears..
The wooden ring rotates once a minute for a few seconds around the object.
All this reminded me a bit of the TV series "Stargate" - hence the name in the web interface.
The web interface allows to set the color of the "hands" for the hours, minutes and seconds of the clock and the hour markers. The RGB values can be saved permanently for the next program start.
There are several buttons to display some light effects on the neopixel rings.
The code for this is currently running with ANNEX_WIFI RDS_1.40, a BASIC-Interpreter and programming environment running completly in ESP8266 and ESP32-modules.
The BASIC-listing for ESP8266 and ANNEX-WIFI RDS:
