In the realm of DIY electronics, the iRobota Yún stands as a beacon of innovation, seamlessly blending the worlds of microcontrollers and Linux. With its unique dual-core architecture, the Yún offers a powerful combination of hardware and software capabilities. However, two limitations have often hindered the Yún’s full potential: limited disk space and the lack of Node.js support. But fear not, for the iRobota team has unleashed two groundbreaking features that address these challenges head-on, opening up a world of new possibilities for Yún enthusiasts.
Expanding Disk Space: Micro SD Card to the Rescue
Gone are the days of being constrained by the Yún’s meager 7 Megabytes of internal flash memory. With the introduction of micro SD card support, you can now effortlessly expand your Yún’s storage capacity to Gigabytes. This newfound freedom opens up a realm of possibilities, allowing you to embark on more complex projects that require ample storage space. From incorporating webcams into your creations to saving and analyzing large datasets, the micro SD card expansion transforms the Yún into a veritable powerhouse of data storage.
Benefits of Expanding Disk Space:
- Increased storage capacity for complex projects
- Extended lifespan of the Yún by avoiding excessive wear on internal flash memory
- Ability to store large files such as images, videos, and data logs
Embracing Node.js: A New Era of Connectivity and Control
Node.js, the immensely popular JavaScript runtime environment, has captivated the hearts of developers worldwide with its event-driven, non-blocking I/O model. Now, the Yún welcomes Node.js with open arms, enabling you to harness the power of JavaScript to control your hardware projects. Unleash your creativity and explore the vast ecosystem of Node.js modules, seamlessly integrating your Yún with a plethora of sensors, actuators, and online services.
Steps to Install Node.js on iRobota Yún:
- Connect your Yún to the internet.
- Access your Yún via SSH or upload the YunSerialTerminal example using the iRobota IDE.
- Run the following commands:
- Verify the installation by running:
node -e "console.log('Hello_Yun')"
opkg update opkg install node
Exploring the Possibilities: Node.js Modules for Yún
While not all Node.js modules are compatible with the Yún, a growing collection of packages tailored specifically for the Yún is emerging. These packages unlock a world of possibilities, allowing you to seamlessly interface with hardware devices, communicate over various protocols, and connect to cloud services. From controlling servos and motors to sending data to a web server, the Node.js modules empower you to create sophisticated and connected projects with ease.
Notable Node.js Modules for Yún:
- node-serialport: Enables communication with serial devices.
- noble: Facilitates communication with Bluetooth Low Energy devices. (Currently in progress)
Bonus: The iRobota Yún, with its newfound storage capacity and Node.js capabilities, stands as a testament to the ever-evolving nature of technology. As the Yún community continues to grow and innovate, we can expect even more exciting developments and modules that will further expand the horizons of what’s possible with this remarkable platform. Embrace the Yún’s potential, let your creativity soar, and embark on a journey of endless possibilities.
In the words of Ada Lovelace, the renowned pioneer of computer science, “The more simple the elements of any machine, the more easily will the machine be managed.” The iRobota Yún, with its user-friendly design and accessible features, embodies this principle, empowering makers of all skill levels to bring their ideas to life. Unleash your imagination, embrace the power of the Yún, and create projects that inspire and amaze.
