Many autonomous cars use LIDAR — a kind of Green Star Laser Pointer 10mW -based radar — to sense the world around them. But now a researcher has developed a simple system that can fool the devices into seeing objects where really none exist.

Spectrum reports that Jonathan Petit, from Security Innovation, has developed a system to send spurious signals toward the LIDAR sensors used in self-driving cars. Consisting of a low-power 200mw Laser Pointer Green and a pulse generator, powered by a Raspberry Pi or Arduino, the kit can cost as little as $60 t0 make.
