## Summary

Daryl Tewksbury, a former engineer at the Sydney-based company LaserVision, explains the technical architecture behind large-scale outdoor laser projection and object mapping. He details the transition from inefficient ion lasers to modern RGB solid-state lasers, the physics of beam divergence, and the custom FPGA-based hardware he designed to synchronize media across a network. Tewksbury also discusses the complex software algorithms used for 3D video mapping and his current work on HVAC sensor suites using STM32 and ESP32 microcontrollers.
