CUTE & ELEGANT DOMINO CLOCK by Kothe

My Clock design is a simpli ed version of the Domino Wall Clock by Carbon Design Group. I have made it smaller to put it on a table or in a shelf and simpli ed the mechanism that shows the time. Instead of using electronic magnetic coil motors to reveal the white dots; what is if not complicated is tedious and a bit expensive, mine uses WS2812B 5050 Addressable SMD smart RGB Leds to show the time.

Step 2: PREPARING THE PARTS

CUTE & ELEGANT DOMINO CLOCK: Page 3

- Stick Base 2 to Base 1 with white wood glue. Use the rectangles as a reference for a correct alignment. (Photo 1)

- Paint the Back Side of the 3 Layers_3.

PAINT ING (Photo 2)

GLUING

- Use Matte Black Paint.

- Glue the Translucent Acrylic Discs to the holes on Layers 1 and 2.(Photo 3)

- Paint the three 3D Frames.

- Paint the Bases. - Paint the Front Side of the 3 Layers_1.

- Glue the White Acrylic Discs to the holes on Layers 3. (Photo 4)

- Paint both Sides of the 3 Layers_4.

Step 3: WIRING THE LEDS - Pre-solder all the leds. (Photo 1) - Glue the leds to the center of the White Acrylic Discs. Pay attention to the direction. (Photo 2) - Wire the leds. 5v, Signal and GND. (Photo 3)

Step 4: ASSEMBLY I - Join up one by one the three layers of the Dominoes to the Dominoe´s frame. The frame has an edge that acts as a stop. The Layers t together perfectly, they don't need glue. (Photo 1)

Step 5: WIRING THE DOMINOES - Arrange the pieces as in Photo 1. CUTE & ELEGANT DOMINO CLOCK: Page 5

- With the information of the ELECTRONIC SCHEMATIC (Next Step) : - Measure distances between components to cut cables to size. - Wire the components according to the ELECTRONIC SCHEMATIC (Next Step). NO T E. Use the duct made on BASE 1 and the square holes on BASE 2 to pass the cables from one dominoe to another. (Photo 2)

Step 6: ELECTRONIC SCHEMATIC To make it even easier there are 3 "Pixel Objects", so each Dominoe pixels (14) are controlled independently.

- Comment the line 35 and Upload again:

//RT C. a d just ( D a t eTime (__ DAT E__, __ T IM E__));

- Upload the code Dominoes_Test.ino to the Arduino Nano before the nal assembly to check out that all the leds are working right. - Upload the code Domino.ino with the line 35 uncommented :

NO T E I. There is a hole on the Units Minutes Frame to access the arduino via USB, so you can modify and upload code at any time.

RT C. a d just ( D a t eTime (__ DAT E__, __ T IM E__)); This will set the time of the computer to the RTC module.

NO T E II. The RTC Module must be the Tiny RTC I2C DS1307 AT24C32 Product on Amazon

Step 7: ASSEMBLY II - Get a USB cable and prepare it as in Photo 1. - Measure the diameter of the USB cable. - Make a hole on Layer_4 of the Units Minutes Dominoe. - Solder the power cable (USB) according to the ELECTRONIC SCHEMATIC. - Glue the 3 Dominoes to the the Base Set Up. Take as reference the holes in the Base and Dominoes.(Photo 2) - Join up the Layer_4 to the Dominoes. (Photo 2)

Step 8: DISPLAY OPTIONS CUTE & ELEGANT DOMINO CLOCK: Page 7

Most numbers can be represented in various ways (Photo 1). So it's up to you how to do it. Take a look at the Domino.ino Arduino Sketch (Step 6). Feel free to modify it to t your needs, turning on/o the pixels in use.

NO T E I. I suggest not to do a very complicated reading. NO T E II. You can control the intensity of the LEDs according to the ambient light conditions of the room.

Also as we are using RGB LEDs you can set any color to the dots (Photo 2).

Compliments! Great idea Thankyou ! Nice project! Thankyou !!! Nice. This is awesome! Thankyou very much!
