Auto Writing Machine by Gakken

The Gakken Auto-Writing Machine is a fascinating mechanical kit that features a large articulated hand capable of drawing pre-programmed shapes. Stick a pen into its holder and watch as the mechanical hand writes the Japanese character for 'A', draws a peace sign, or writes the name 'Tosa.'

The auto-writer uses three rotating plates caught by two sliders that pull the spring-loaded hand to trace each shape. It's a captivating demonstration of cam-driven mechanical engineering and a rewarding project to assemble.
