A software engineer documents building a wall-mounted LED lamp from scratch using WLED, aluminum extrusions, and SK6812 LED strips without prior woodworking or electronics experience
This project demonstrates how accessible custom lighting solutions have become for engineers without domain expertise. The use of standardized components like aluminum extrusions and open-source software (WLED) lowers the barrier to integrating programmable lighting into home environments. It also highlights the practical challenges of power distribution and mechanical design when scaling DIY electronics projects

Project used WLED software and QuinLED Dig-Uno controller to drive 220 individually addressable SK6812 LEDs across a 180cm span
Aluminum extrusion frame (3030/3060) provided structural support while hiding power supply and control electronics behind wooden panels
Power injection planning and LED diffusion were critical to avoid brightness inconsistencies and visible hotspots
THE READ
What the cluster adds up to.
The project shows how open-source lighting control software like WLED can be combined with commodity hardware to create custom lighting solutions. The engineer selected SK6812 LED strips for their addressability, though the 5V design required careful power injection planning to maintain consistent brightness across the 180cm span. This demonstrates a common tradeoff in LED projects: higher control granularity often comes with increased power distribution complexity.
Mechanical design choices reveal how DIY projects often rely on standardized components to compensate for lack of domain expertise. The aluminum extrusion frame served multiple purposes: structural support, mounting point for wooden panels, and concealed housing for electronics. This approach mirrors how professional engineering projects use modular components to reduce design risk, though the engineer noted concerns about structural integrity that would need validation in larger implementations.
The project highlights several practical considerations that emerge when scaling hobbyist electronics. Power supply selection (75W Meanwell) was dictated by LED count, while LED diffusion became critical to avoid visible hotspots. The engineer's iterative CAD modeling in OpenSCAD suggests how digital tools can help validate physical designs before committing to material cuts, a workflow that parallels professional prototyping processes.
The documentation reveals how community resources shape DIY engineering projects. The engineer relied on comparison videos for component selection (QuinLED controller, LED diffusers) and power calculations, showing how shared knowledge accelerates project development. This collaborative aspect mirrors how professional engineering teams leverage internal documentation and vendor resources to make informed component choices.
