Aliens' M314 Motion Tracker Reborn with Modern Tech
A creative tech enthusiast, known only as RobSmithDev, has brought a classic piece of movie tech into the 21st century. Using the DreamHAT+ Radar HAT for the Raspberry Pi, they've created a functional replica of the M314 Motion Tracker from the Aliens film series.
The original M314 Motion Tracker, featured in the 1986 film Aliens, was a captivating piece of future-tech. Now, RobSmithDev has given it new life with modern electronics. The DreamHAT+ Radar HAT, a short-range radar module, detects motion within a few meters, making it perfect for this project.
RobSmithDev's replica works similarly to the one in the movie. It's not the first attempt to recreate the M314 Motion Tracker, but the use of modern electronics sets this build apart. The result was so impressive that it was featured in a Hackaday article on October 2, 2025, though the creator's name was not specified.
RobSmithDev's functional M314 Motion Tracker replica is a testament to the power of modern technology and creative ingenuity. By combining the DreamHAT+ Radar HAT with the Raspberry Pi, they've brought a piece of cinematic history into the present day, proving that even classic movie props can be given a high-tech makeover.
