This project is a high-RPM LEGO vacuum engine powered by household vacuum pressure and paired with a custom multi-speed gearbox. The engine speed is continuously monitored by an onboard control circuit, which automatically engages the clutch and shifts gears using servo actuators. Instead of manual shifting, the system uses predefined RPM thresholds to select the appropriate gear in real time, keeping the engine running smoothly and efficiently. The result is a closed-loop, automatic transmission system that maintains stable operation while the engine speed changes.
