In the world of 3D printing, there's a growing trend that enthusiasts and professionals alike have come to appreciate: time-lapse videos that showcase the intricate process of layer-by-layer construction. If you've ever watched one of these mesmerizing clips, you've likely noticed how they often highlight a print coming together seamlessly, akin to a magical transformation. However, achieving high-quality time-lapses isn't as straightforward as it might seem. The traditional method involves substantial setup and can often require sophisticated tools like plugins for OctoPrint, adding complexity for those who merely wish to capture stunning visuals of their prints.

To simplify this process, innovative creator [Whopper Printing] has introduced a remarkable device called LayerLapse. This compact printed circuit board (PCB) is ingeniously designed to trigger a DSLR or mirrorless camera whenever its remotely-mounted hall effect sensor detects a magnet. The beauty of LayerLapse lies in its straightforward implementation, allowing users to focus on their 3D printing projects rather than getting bogged down in complicated setups.

The operational principle of LayerLapse is elegantly simple. Users need only attach a small magnet to their extruder and incorporate a bit of additional G-code into their printing routine. This G-code will instruct the printer to park the magnet directly over the sensor at the conclusion of each layer, activating the camera and capturing a still image. Moreover, the LayerLapse PCB includes a spare General Purpose Input/Output (GPIO) pin, which can be utilized to trigger another device or function during the printing process. While it may not be immediately clear what else could benefit from this feature, the potential for creative applications is vast and exciting.

Currently, [Whopper Printing] offers the LayerLapse as a fully assembled product for purchase, providing a hassle-free option for those eager to elevate their 3D printing documentation. For those inclined towards DIY projects, plans for a kit version are reportedly in development. Additionally, comprehensive instructions are available for those who wish to construct a custom version of the LayerLapse using their choice of microcontroller. The firmware for this innovative device is also accessible under the MIT license, encouraging tech enthusiasts to tinker and modify it to their liking.

As hardware hackers, we have a profound appreciation for the independent and self-contained nature of the LayerLapse solution. However, it’s worth noting that for individuals who are already using OctoPrint to manage their printers, it may be more efficient to explore the various time-lapse plugins available within that ecosystem. Ultimately, the LayerLapse stands out as an excellent option for both novice and experienced users seeking to create stunning time-lapse videos of their 3D printing projects.
