LED Lights — Office (WLED & WS2812b)
Individually addressable LED strips controlled by ESP8266/ESP32 running WLED, integrated with Apple HomeKit and Home Assistant to respond to time of day, calendar events, and sensor data.
What It Is
Information is transmitted through the electromagnetic spectrum using modulation, frequency allocation, and protocol layering under physical and regulatory constraints.
What This Domain Trains You To Notice
This domain is valuable because physical and infrastructure systems make constraints legible. They show how components fit together, where tolerance matters, how failure propagates, and what it takes to keep an assembly reliable over time.
Why It Transfers
The broader payoff is transfer. Once you learn to see interfaces, bottlenecks, and feedback in a physical substrate, you get better at spotting the same patterns in software, organizations, and markets. This domain gets more useful when it is compared with adjacent systems instead of being treated as a silo. That is where reusable judgment starts to form.
