The evolution of Minecraft over the past 15 years has transformed it from a simple digital playground into a multifaceted universe filled with intricate functionalities. Once merely a platform for mining and basic construction, the game now allows players to craft sophisticated tools, including a compass that can guide them to specific locations like a lodestone or their world spawn point. This innovation has inspired a fascinating project by chaosgoo, which has brought the in-game compass into the physical realm.
Bridging Virtual and Physical Worlds
The DIY compass created by chaosgoo is a remarkable piece of technology that mirrors the pixelated design of its virtual counterpart while functioning effectively in real life. Users can set a destination using a companion app, whether it be their home, a favorite store, or even a curious geological find in a local park. The compass needle adeptly adjusts its orientation, ensuring it always points toward the designated target.
Achieving this level of functionality required chaosgoo to engineer a custom printed circuit board (PCB). This intricate board not only looks aesthetically pleasing but also features a printed crafting recipe for the in-game compass on its reverse side, along with relevant code. At its core lies the ESP32-C3-MINI microcontroller, which integrates both Wi-Fi and Bluetooth capabilities, complemented by essential components such as a USB connector, a lithium battery charger, and a digital compass.
One of the standout features of the PCB is its array of 42 TX1812IJA-F01 RGB LEDs, which are individually addressable, akin to the well-known WS2812b. The use of PET LGT075J material as a light diffuser creates a stunning visual effect, allowing the compass needle to appear as if it is composed of moving voxels rather than glowing LEDs, particularly in daylight—a truly impressive feat of design.
The device’s enclosure, designed for 3D printing, is compact enough to fit comfortably in the palm of a hand, making it portable and easy to carry. For those interested in embarking on their own crafting journey, the process may present some challenges, as the documentation primarily exists in Chinese and focuses mainly on the software aspect. However, aspiring builders can access the 3D models on MakerWorld, the PCB files on OSHW Hub, and additional resources on GitHub.
