We all know how useful post-it notes are to remind us of the many things we have to do in our busy lives. Well, now you can build your very own electronic version.
The guys over at Popsci have built an electronic post-it note, a very cool idea.
“Pick up milk.” “Feed dog.” “Finish homemade nuclear sub.” Like many people, I can’t function without writing little reminders to myself. But using one paper sticky note after another causes a lot of clutter and can be pretty wasteful. Instead, assemble a bunch of surplus parts into a digital note system for your kitchen or office. Just write out your message with your fingertip on a computer trackpad, and it appears on an LCD screen.
When you’re done, press a button and the screen is erased. Add a rechargeable battery and an enclosure, and you have unlimited (and eco-friendly) note-making capability. The project does require some computer code to drive the LCD; you can copy it here. If you can just remember that, you’ll be good to go.
Why Go Digital?
Switching from traditional paper post-it notes to an electronic version offers several advantages. Firstly, it significantly reduces paper waste, making it an eco-friendly alternative. In a world increasingly conscious of environmental impact, this small change can contribute to a larger effort to reduce deforestation and waste. Additionally, electronic notes eliminate the clutter that often accumulates with paper notes. Imagine a clean, organized workspace where all your reminders are neatly displayed on a single screen.
Moreover, electronic post-it notes can be more versatile. You can easily update or delete notes without the need for physical disposal. This feature is particularly useful for tasks that frequently change or for brainstorming sessions where ideas are constantly evolving. The ability to save and organize notes digitally can also enhance productivity and efficiency.
Building Your Own Electronic Post-It Note
Creating your own electronic post-it note system might sound daunting, but it’s a manageable project even for those with basic DIY skills. The essential components include a computer trackpad, an LCD screen, a rechargeable battery, and an enclosure to house the parts. The trackpad allows you to write messages with your fingertip, which then appear on the LCD screen. When you no longer need a note, a simple press of a button erases the screen, readying it for the next message.
One of the key aspects of this project is the computer code required to drive the LCD screen. Fortunately, Popsci provides the necessary code, making it easier for you to get started. If you’re new to coding, this project can also serve as a great introduction to basic programming concepts. The satisfaction of seeing your handwritten message appear on the screen is well worth the effort.
To make the project even more user-friendly, consider adding features like different color options for notes, the ability to save notes to a digital archive, or even integrating voice-to-text capabilities. These enhancements can make your electronic post-it note system even more functional and enjoyable to use.
