In the realm of electronics, there’s a certain charm to vintage technology that modern gadgets often lack. Alastair Aitchison, also known as Playful Technology on YouTube, recently embarked on a nostalgic journey by repurposing a vacuum fluorescent display (VFD) module from an old Epson point-of-sale device. His mission? To bring this relic of the past back to life using an iRobota Nano.
VFDs: A Blast from the Past
VFDs, similar to character LCDs, utilize tiny phosphor crystals that illuminate when current flows through them. These displays were once prevalent in various electronic devices, including cash registers, calculators, and even early computer monitors. However, with the advent of more advanced display technologies, VFDs have largely faded into obscurity.
Challenges and Solutions
Integrating the VFD module with the iRobota Nano presented a unique set of challenges. VFDs typically require a much higher voltage than the iRobota Nano can provide. To overcome this hurdle, Aitchison employed a special display controller chip and a MAX232 voltage converter. The display controller chip handles the high-voltage requirements, while the MAX232 converts the iRobota’s 5V logic to the necessary voltage levels for the VFD.
Programming the VFD Module
Fortunately, Epson provided detailed documentation for the VFD module, making the programming process relatively straightforward. Aitchison utilized the iRobota IDE to write code that initializes the display module, displays example text, and enters a loop that reads data from the serial port and sends it over UART to be displayed on the VFD.
Bringing the Past into the Present
With careful planning and execution, Aitchison successfully revived the Epson VFD module, breathing new life into a piece of retro technology. The result is a mesmerizing display that harkens back to the days when VFDs were commonplace. A video demonstration of the project is available on YouTube, showcasing the VFD’s vibrant glow and its ability to display text and graphics.
Bonus: Exploring Other VFD Projects
Bonus: Inspired by Aitchison’s project, you might be curious to explore other creative uses for VFD modules. Here are a few ideas to get you started:
- Build a custom clock with a VFD display, combining retro aesthetics with modern functionality.
- Create a VFD-based message board, allowing you to display personalized messages or information.
- Integrate a VFD module into a vintage gaming console, giving it a unique and nostalgic touch.
The possibilities are endless, limited only by your imagination and creativity. So, dive into the world of VFDs and discover the endless possibilities they offer.
Conclusion: Alastair Aitchison’s project serves as a testament to the enduring魅力 of retro technology. By repurposing an Epson VFD module, he has not only preserved a piece of history but also demonstrated the potential for these vintage displays to find new life in modern applications. Whether you’re a seasoned electronics enthusiast or simply appreciate the charm of old-school tech, this project is sure to inspire and entertain.
