Build Your Own Mini Moon Display with ESP32-S3 - DIY Desk Gadget (2026)

The Moon, our closest celestial companion, often goes unnoticed as we go about our daily lives. But what if we could bring a tiny, ever-changing version of the Moon to our desks? That's exactly what [Karsten Mueller]'s innovative project, Mondansicht für den Schreibtisch, aims to do. This project is a testament to the power of technology to bring a touch of the universe into our everyday lives, and it's a fascinating exploration of how we can use technology to connect with the cosmos.

The device itself is a marvel of simplicity and ingenuity. It consists of a circular display, an ESP32-S3 microcontroller, and a 3D-printed case. But the true magic lies in the software. It's not just a static display of the Moon's phases; it's a dynamic, ever-changing representation that takes into account your local time, latitude, and longitude. This means that the image on your desk will approximate what the Moon looks like from your perspective, even if you can't see it in the sky at that moment.

The project initially used a photograph of the Moon taken by [Karsten] himself, but it also has the option to pull imagery from NASA. This dual approach ensures that the display is both personal and scientifically accurate. The project's German original write-up is available, and there's also an English page on Hackaday.io, making it accessible to a global audience.

What makes this project particularly fascinating is how it challenges our perception of the Moon. We often think of it as a static, unchanging object in the sky. But by bringing it to our desks and making it dynamic, [Karsten] reminds us of the Moon's ever-changing nature and its connection to our own time and place on Earth. It's a beautiful reminder of the vastness of the universe and our place within it.

The project also raises a deeper question about our relationship with technology. As we become more immersed in the digital world, how can we use technology to connect with the natural world? Mondansicht für den Schreibtisch is a brilliant example of how technology can be used to bridge the gap between the digital and the physical, and it invites us to reconsider our relationship with the cosmos.

In my opinion, this project is a testament to the creativity and ingenuity of human beings. It's a reminder that even the smallest projects can have a profound impact, and it encourages us to explore new ways of connecting with the world around us. So, if you're looking for a way to bring a touch of the universe into your life, consider building your own Moon display. It's a fascinating project that will not only brighten your desk but also your understanding of the cosmos.
