Tiny but mighty: YouTuber turns wizard with PCB motors
Is that a frog? A grasshopper? No! It's a flexible actuator prototype...that can bounce.
Twenty-seven-year-old engineer and YouTuber Carl Bugeja's miniature jumping circuit is basically a coil printed on the flexible PCB (Printed Circuit Board) acting as an electromagnet. The coil behaves as the static side of the actuator. A stack of two permanent magnets is attached to the circuit, resembling arms. The tiny 'living' circuit leaps around the table with ease, much to the awe of Bugeja's audience.
