A project enthusiast has successfully created a custom RGB 14-segment display, filling a gap in the market for addressable LED components. This innovative display, designed by EastMakes, utilizes SK6805 RGB LEDs with a compact 1.5 x 1.5 cm footprint, allowing for vibrant and customizable lighting effects.
The journey began when EastMakes realized that a suitable RGB 14-segment display was unavailable. In response, he decided to design his own version, starting with a layout crafted using KiCad, a popular software for electronic design automation. The assembly and manufacturing of the printed circuit board (PCB) were relatively straightforward, but the key to the display’s effectiveness lay in its diffuser design.
Multiple Diffuser Approaches Tested
EastMakes explored various diffuser options to enhance the display’s performance. Among these were FR4 boards with translucent segments incorporated into the soldermask, as well as 3D printed prototypes made from both white and black PLA filament. The FR4 approach, particularly using 0.8 mm thick PCBs, produced satisfactory results, with the addition of through vias in the 1 mm version significantly increasing the overall brightness.
The 3D printed prototypes also showed promise, though they highlighted the importance of a well-fitted diffuser panel to minimize light bleeding between segments. By ensuring a snug fit around the LEDs, the display could achieve a more refined and visually appealing output.
Potential for Future Development
The successful creation of this RGB 14-segment display showcases the potential for innovative projects within the LED component market. As EastMakes continues to refine his design, there is a growing interest in how this technology can be adapted for various applications. The combination of addressable RGB capability with the classic 14-segment layout may attract hobbyists and professionals alike, providing new opportunities for creative expression in electronic displays.
This development exemplifies the spirit of innovation in DIY electronics, where individuals take it upon themselves to create solutions when commercial products fall short. EastMakes’ project is a testament to the possibilities that arise from combining creativity with technical skills, inspiring others to experiment with similar designs.
