Mixed Reality Model Train (2020)
H0 gauge Märklin locomotive refitted with a DC motor and a motor driver, Arduino Nano, NRF24l01 2.4Ghz transceiver, 4K Digital camera, 5.8Ghz 4K Digital A/V transmitter, Custom designed PCB, Custom built 4-cell Lipo, 3D Printed chassis, Custom software, various electronics
This highly compact but capable H0 gauge spec model train is designed and built for IMG-lab which presented a mixed-reality attraction for a theme park. It was opeated in trade shows around the world, including 2019 IAAPA Orlando. Other than the train - the structure, ride, and digital contents - were built by IMG-lab, in close coordination with the external triggers and timers within the train.
