Building a mini ternary computer

Building a mini ternary computer, a fascinating project. A high-level outline to get you started.

A fascinating project

Building a mini ternary computer can be a fascinating project. A ternary computer uses ternary logic, which has three possible states (usually represented as -1, 0, and +1) compared to the binary logic, which has only two (0 and 1). While it’s an unconventional approach compared to modern binary computers, it can be a great learning experience.

GitHub Projects and Code Repositories

Online Forums and Communities

  • Stack Exchange – Electrical Engineering or Computer Science: You can find discussions related to ternary computing and ask questions to the community.
Keep in mind that since ternary computing is not as common as binary computing, the available resources might be limited. It may require some additional research and experimentation on your part to dive deeper into the topic and build your mini ternary computer. Also, consider exploring more recent resources as developments in unconventional computing may have occurred.

List of available components

Finding commercially available components specifically designed for ternary computing might be challenging since binary computing dominates the market. However, you can still create a mini ternary computer using conventional electronic components and represent ternary logic using different voltage levels or signal encoding schemes. Here are some components you can consider using for your project:

Logic Gates

Use standard digital logic gates such as AND, OR, NOT, and XOR gates. You can create ternary logic gates by combining multiple binary gates creatively to operate on ternary signals.


Transistors are fundamental components in digital circuits. You can use NPN and PNP bipolar junction transistors or MOSFETs to build the logic gates and other circuitry required for your ternary computer.


Resistors are essential for setting voltage levels and current flow in your circuits. They are used in various parts of the CPU, including voltage dividers and biasing networks.


Capacitors are used in filtering and timing circuits. Depending on your design, you may need them in different parts of the computer.


Diodes can be useful for signal routing and protection.

Flip-Flops and Latches

These are essential for creating memory elements in your computer.

Clock Source

You’ll need a stable clock source for synchronization in your computer.

Display/Output Components

Depending on your computer’s design, you may need LEDs, 7-segment displays, or other output devices to show results.

Input Components

You can use switches or buttons for manual input to your computer.

Breadboard or PCB

For prototyping, you can use a breadboard to connect the components temporarily. If you want a more permanent solution, design and fabricate a printed circuit board (PCB).

Power Supply

Make sure you have an appropriate power supply for the voltage levels used in your ternary logic.

Remember that when working with unconventional computing methods like ternary logic, you may encounter challenges in terms of available components and community support. You may need to experiment, test, and innovate in building and implementing ternary logic circuits. Additionally, consider exploring newer developments and technologies that might have emerged since my last update.

Always prioritize safety when working with electronic components and circuits. If you’re unsure about a specific component’s suitability or compatibility with your design, seek guidance from experienced electronics enthusiasts or engineers.

Missing components to bring the building to a good end

Building a mini ternary computer can be a challenging endeavor, especially due to the unconventional nature of ternary logic and the limited availability of dedicated components. As a result, you might encounter some limitations or challenges in your project. Here are some potential considerations and missing components that you might encounter:

Ternary Logic Gates

While you can build ternary logic gates using combinations of binary gates, dedicated ternary logic gate ICs are not readily available in the market. This may require you to design custom logic circuits using discrete components.

Ternary Memory Components

Memory elements that directly support ternary storage (e.g., ternary flip-flops or latches) might not be available. You may need to design custom memory elements using ternary logic.

Ternary ALU Components

Creating a fully-featured ternary Arithmetic Logic Unit (ALU) with conventional components can be complex. Designing a custom ternary ALU circuit is likely necessary.

Instruction Set Support

Building a complete instruction set for your ternary computer might be challenging due to the limited availability of ternary-specific components. You may need to carefully design instructions that can be executed with your available resources.

Clocking and Timing

Ensuring precise and stable ternary clock signals might be difficult, which can affect the performance and reliability of your computer.

Simulation and Testing Tools

Simulating ternary logic circuits and testing them can be more challenging compared to binary circuits, as dedicated tools might be limited.

Community and Support

Finding a community of enthusiasts and experts in ternary computing might be more challenging compared to binary computing, which can limit access to resources and support.

Integration Challenges

Combining different ternary components and designing a cohesive system might require creative problem-solving and iterative testing.

Despite these challenges, building a mini ternary computer can still be a rewarding and educational experience. You may need to leverage your skills in electronics, digital design, and logic to overcome these obstacles.

To address some of these limitations, consider exploring the latest research and advancements in unconventional computing, ternary logic, and related technologies. Additionally, look for open-source projects and communities that might be working on similar projects or share valuable insights.

Remember that building a mini ternary computer can be a complex task, and it might not match the performance or efficiency of conventional binary computers. However, the experience of exploring unconventional computing and designing a unique system can be highly valuable in its own right. Keep experimenting, learning, and iterating to bring your project to a successful conclusion.

Dedicated commercially available components for ternary computing do not exist, do they?

Dedicated commercially available components specifically designed for ternary computing were not widely available. The computing industry has been primarily built around binary logic, and ternary computing has not gained mainstream adoption.

It’s important to note that there might have been advancements or developments in the field of ternary computing. The technology landscape is continuously evolving, and it’s possible that there have been research breakthroughs or niche market developments that I’m not aware of.

If you are interested in exploring ternary computing and related components, conduct further research, check for the latest publications, academic papers, and seek out any communities or forums that focus on unconventional computing methods. There might be specialized vendors or researchers working on experimental ternary computing projects, and they could have developed custom components or prototypes for their experiments.

Always stay curious and up-to-date with the latest developments in the field you are interested in, as technology can progress rapidly, and new opportunities may arise.
