Makers looking for a project to keep them busy this weekend may be interested in a simplified version of the Domino Wall Clock created by the Carbon Design Group. Instructables member Kothe has kindly published full instructions, 3D printing designs, and electronic layouts for you to easily build your own simplified version.
Using an Arduino Nano microcontroller together with addressable RGB LEDs, the tabletop version of the wall-mounted original Domino clock offers a great way to learn more about controlling LEDs using Arduino coding.
Project Overview
The original Domino Wall Clock is a fascinating piece of design that uses electronic magnetic coil motors to reveal white dots on a black surface, mimicking the appearance of domino tiles. However, this mechanism can be quite complex and costly to replicate. Kothe’s simplified version replaces these motors with WS2812B 5050 Addressable SMD smart RGB LEDs, which are not only easier to work with but also more affordable.
“I have made it smaller to put it on a table or in a shelf and simplified 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.”
Building Your Own Domino Clock
To build your own Domino clock, you’ll need a few essential components:
1. Arduino Nano Microcontroller: This small yet powerful microcontroller will be the brain of your clock, handling all the logic and control for the LEDs.
2. WS2812B 5050 Addressable RGB LEDs: These LEDs are individually addressable, meaning you can control each one independently to create the desired time display.
3. 3D Printed Parts: Kothe has provided 3D printing designs that you can use to print the housing and other necessary parts for your clock.
4. Power Supply: Ensure you have a reliable power source to keep your clock running smoothly.
5. Wiring and Soldering Tools: Basic tools for connecting your components together.
The project involves several steps, including 3D printing the parts, assembling the electronics, and programming the Arduino Nano. Kothe’s instructions on Instructables are detailed and easy to follow, making this a great project for both beginners and experienced makers.
Step-by-Step Instructions
1. 3D Printing: Start by 3D printing the parts using the provided designs. This will include the main body of the clock, as well as any additional components needed to hold the LEDs and microcontroller in place.
2. Assembling the Electronics: Once you have all your parts printed, you can begin assembling the electronics. This involves connecting the WS2812B LEDs to the Arduino Nano and ensuring everything is properly wired.
3. Programming the Arduino: With the hardware assembled, the next step is to program the Arduino Nano. Kothe has provided the necessary code, which you can upload to your microcontroller using the Arduino IDE.
4. Final Assembly: After programming, you can complete the final assembly of your clock. Ensure all components are securely in place and test the clock to make sure it displays the time correctly.
Learning Opportunities
Building this Domino clock is not just about creating a functional timepiece; it’s also an excellent learning opportunity. You’ll gain hands-on experience with 3D printing, electronics assembly, and Arduino programming. These skills are valuable for any maker and can be applied to a wide range of other projects.
