DIY Grow-Light System Tracks Plant Growth
3.9
A maker named Bubs built a motorized grow-light system that keeps an LED array focused on the top of a plant as it grows. He combines red/blue LEDs with optical lenses, a Python light simulator, PCBWay SLM aluminum 3D-printed heatsink mounts, ESP32-driven drivers, and a motorized winch to adjust height and schedule intensity. The design enables energy-efficient indoor lighting and future sensor automation.
Key Points
- 1Implements motorized winch and adjustable LED array to track plant height and focus light
- 2Reduces photon waste using red/blue LEDs and lenses that narrow throw for better absorption
- 3Enables energy-efficient indoor growth and future sensor automation via ESP32-controlled drivers and GPIO
Scoring Rationale
Practical maker innovation rates modestly due to niche scope and single-source reporting despite clear actionable hardware design.
