In a world enthralled by the wonders of science fiction, James Lewis embarked on an extraordinary quest: to bring the iconic tricorder from Star Trek into reality. His creation, a DIY tricorder, not only captures the essence of the original device but also serves as a testament to the boundless possibilities of human ingenuity.
The Genesis of an Idea: A DIY Tricorder Takes Shape
Inspired by the tricorder’s ability to measure light levels and temperature, Lewis set out to create a functional replica using modern technology. At the heart of his device lies an MKR Zero microcontroller, a phototransistor for light detection, and an analog temperature sensor, all housed within a 3D-printed enclosure.
Unveiling the Tricorder’s Intricate Design
The tricorder’s enclosure, meticulously designed in Fusion 360, mirrors the aesthetics of its fictional counterpart. A hinge mechanism allows for easy opening and wiring harness management, while a VL53L0X time-of-flight sensor detects when the hinge is open, activating the OLED information screens.
Intuitive Interface: Bringing the Tricorder to Life
To ensure user-friendly operation, Lewis incorporated four buttons into the tricorder’s design, utilizing the SAM D21’s capacitive touch controller for simple inputs. These buttons enable users to navigate the device’s functions effortlessly.
Sound and Functionality: A Multifaceted Experience
Beyond its visual appeal, the DIY tricorder also boasts audio capabilities. It can play looped WAV files stored on an SD card through a DAC, external op-amp, and speaker circuit. This feature adds another layer of immersion to the tricorder experience.
Open-Source Accessibility: Sharing the Tricorder’s Blueprint
In the spirit of open-source collaboration, Lewis has generously shared the schematics, code, and design files for his DIY tricorder. This allows fellow enthusiasts to embark on their own tricorder-building adventures, fostering a community of innovation.
A Build Log and Demonstration: Witnessing the Tricorder’s Creation
To document his journey, Lewis meticulously maintained a build log, providing detailed insights into the construction process. Additionally, he created a demonstration video showcasing the tricorder’s functionality, offering a glimpse into the future of DIY technology.
Bonus: Lewis’s DIY tricorder serves as a beacon of inspiration, demonstrating the transformative power of imagination and perseverance. It invites us to embrace our inner explorers, to push the boundaries of possibility, and to create tangible expressions of our dreams.
As we stand on the precipice of a new era, where science fiction and reality converge, Lewis’s DIY tricorder stands as a testament to the indomitable spirit of human ingenuity. It is a reminder that with passion, creativity, and a willingness to learn, we can materialize the wonders of tomorrow, today.
