Spectrum Clock

Intdroduction

    I got the idea to represent time as a spectrum of colors. There are already similar ideas on the Internet, but they are a little difficult to accurately determine the time. I wanted to make a simpler and more understandable clock. To represent the time, I decided to use two hue wheels, one for the hour and one for the minutes and seconds. In the center, I decided to place the yin and yang symbol, the upper part of which will display hours and the lower part of the minute, two dots, will display seconds.

Design

    For the project, I decided to use a WS2812b addressable LED strip (I took 1 meter 144 LEDs), an Arduino Nano and a thin 22AWG wire. I also designed the case and 3D printed it.

     Since I had to strip a lot of wires, the tool came in handy for me, which I found on Thingiverse.com.

Assembly

     First you need to cut 60 LEDs with one tape and 16 LEDs one by one. Then you need to tin all the contacts on the LEDs. Next, you should glue 16 LEDs to the convex areas. The main thing when gluing is to observe the sequence so that the plus and the ground do not intersect. Then you should measure the wires, strip them and, most importantly, tin them in advance. When you solder the wires to the contacts of the LEDs, touch the soldering iron for no more than one second in order not to melt the plastic. It should look like the picture below.

     Then the panel is screwed to the main body with two small screws. The tape with 60 LEDs fits into the outer ring. The wires from this tape are threaded through a special hole and soldered. It should look like the picture below.

    I also had to stick a little foil on the inside to reflect the light better, otherwise it would be dark in this place.image

 

Connection

    The control wire from pin D6 of the Arduino to the DIN pin of the LED strip should be connected through a 200-500 ohm resistor (I used 470 ohm). It is also important that the power supply to the LED strip is separate.

    Stephen, You definately do, get a 3D printer immediately - it is so much fun. You can make the widget bits that you actually want. Dubbie

    I like the idea. The 3D printing is pretty good and very neat fixing of the LEDs. Dubbie

    Two outer rings are needed to display the time in different modes and also to create different lighting effects. Large ring for minutes and inner for hours. So far I have been able to come up with two modes. The first mode displays the spectrum on all rings, and on the yin yang sign changes color and displays the time (upper part of hours; lower part of minutes; points are seconds). The second mode displays the time as a simple analog clock with the outer ring of the minute and the inner clock (photo below). This is a prototype, so the design and different modes will be added and improved. It's just that I don't have much time so I haven't had time to post the code yet.

    What do the two outer rings do?
