Edge-lit 7-Segment Display Clock Using Raspberry Pi Pico -- Episode-653

In this episode of Element14 Presents, Katie introduces us to her latest project: creating an acrylic edge-lit clock. The inspiration stemmed from discussions in the community about edge-lit dioramas, sparking Katie's interest in utilizing a laser cutter for this endeavor. Beginning with a simple etched acrylic design, she outlines her vision for illuminating each number on the clock face.

To achieve this, Katie decides to incorporate a PCB with neopixels, providing flexibility for future modifications. Initially designed as a clock, the PCB layout allows for the potential integration of various shapes or even diorama elements, as suggested by the community. She considers different configurations for displaying numbers, ultimately opting for a seven-segment display approach for its versatility and symmetry. 

With the PCB design finalized, Katie shares insights into her modular approach, breaking down the components and functionalities of the Raspberry Pi Pico-based real-time clock PCB. Emphasizing flexibility, she discusses power options, buzzer integration, and near-pixel outputs for illuminating the acrylic segments. The meticulous planning extends to the PCB layout, optimizing space for future expansions. 

Moving on to the case design, Katie showcases a sleek, functional enclosure tailored for her project's needs. Despite encountering a setback with the size exceeding the printer bed limits, she devises a solution by splitting the case into two halves for printing. This resourceful approach highlights her adaptability in overcoming technical challenges. 

Transitioning to the laser cutting phase, Katie demonstrates her proficiency in engraving and cutting acrylic segments for the clock display. She recounts the refurbishment process of her laser cutter, underscoring the project's hands-on nature and cost-effectiveness. Despite the complexity of aligning and cutting multiple sheets, she remains focused on achieving precise results. 

After receiving the PCBs and assembling them using a DIY soldering method, Katie proceeds to integrate them into the 3D-printed enclosure. Despite the challenge of assembling a split-case design, she ensures stability and functionality. Upon completion, she unveils the fully assembled clock, showcasing its functionality and aesthetic appeal. 

Reflecting on the project's journey, Katie is pretty happy with the result despite any issues and setbacks along the way.
