Is this possible? What type of equipment and knowledge would I need to create it? I’ve

Is this feasible? What kind of equipment and expertise would I require to bring this idea to life?

The concept involves stripping the internals of a graphing calculator and replacing them with an Orange Pi running Android. This setup would boot into a calculator mode while also allowing the use of Android apps and web browsing, enabling access to tools like ChatGPT and photo applications.

However, I have a few concerns: I’m worried that the Orange Pi might be too large to fit inside the calculator’s casing, and I lack coding skills, which could complicate the project significantly.

  1. Your idea to replace the internals of a graphing calculator with an Orange Pi running Android is definitely ambitious but could be an interesting project! Here are some considerations and steps to help you get started:

    Feasibility

    1. Size: Check the dimensions of the Orange Pi model you intend to use against the internal space of the graphing calculator. If size is an issue, consider smaller alternatives like the Raspberry Pi Pico or other microcontrollers that can run lightweight operating systems.

    2. Power Supply: Be mindful of how you will power the Orange Pi. Graphing calculators typically run on batteries, so you’ll need to find a compatible power solution.

    3. Display Interface: You’ll need to integrate the Orange Pi with the calculator’s display. This might require using an HDMI or LCD controller depending on your display type.

    Equipment Needed

    1. Orange Pi: Select a model that’s powerful yet small enough to fit in your calculator shell.
    2. MicroSD card: For the Android OS and storage for apps.
    3. Power management: Consider a battery management system for charging and power regulation.
    4. Wires and connectors: For connections between the Orange Pi and the calculator display/input.
    5. Tools: Basic electronic tools like a soldering iron, wire strippers, and possibly a Raspberry Pi camera if you want to integrate camera functions.

    Knowledge Required

    1. Basic Electronics: Understanding principles of soldering, circuit connections, and power supplies.
    2. Programming: Familiarize yourself with programming, especially in Python or Java, as these are commonly used for Android app development.
    3. Android Development: Basic knowledge of Android app development can help you customize the calculator mode or create your own apps.

    Resources

    1. Online Tutorials: Look for online courses or tutorials on Android development, Raspberry Pi, or Orange Pi projects. Websites like Coursera, Udacity, or free resources on YouTube can be helpful.
    2. Forums and Communities: Join forums like the Raspberry Pi forums, Reddit communities, or Discord groups focused on hardware projects. These platforms can provide support, feedback, and suggestions from like-minded enthusiasts.
    3. Project Documentation: Review similar projects online to see how others tackled challenges in embedding computers into small devices.

    Alternative Consideration

    If coding is a major barrier, consider teaming up with someone who has software development experience or looking for pre-existing open-source projects that you could repurpose or modify for your needs.

    This project could be a great way to learn more about electronics, coding, and systems integration. Just take one step at a time, and adjust your expectations along the way! Good luck!
