A hobbyist has built a fully functional 1:150 scale Toyota ProBox remote control car, equipped with working lights, steering, and driving capabilities. This project highlights advances in micro-model engineering and remote control technology, making it a notable development for scale model enthusiasts and hobbyists.
The project involves converting a miniature Toyota ProBox model into a remote-controlled vehicle with detailed operational features. The builder installed a tiny 25 mAh Li-polymer battery, two small motors for steering and driving, and used gears salvaged from mechanical watches. Position tracking is managed via photoreflectors, and the car is controlled through an infrared SMD receiver module. Powering and programming are facilitated through terminals on the bottom of the model.
In a demonstration video, the car successfully navigates a miniature track, with operational headlamps, tail lights, blinkers, and stop lights, including a rear top light. Schematics and software for the project are publicly available via links provided by the builder, encouraging others to replicate or build upon the design.
