Adafruit Auto Writing Machine by Gakken

The Gakken Auto-Writing Machine offers a hands-on exploration of mechanics with its fascinating large mechanical hand. Once assembled, this innovative kit allows you to insert a pen and watch as the hand elegantly scripts the Japanese character 'A', a peace sign, or the name 'Tosa'.

This ingenious device operates with three rotating plates and dual sliders that guide the hand via a clever spring-loaded mechanism, crafting a captivating demonstration of motion art. Though the included capabilities are limited, an online app extends creativity by enabling users to design custom plates in PDF format for laser or hand cutting.

Notably, the package lacks a pen, but a calligraphy pen fits perfectly, and a single AA battery powers the unit. While intricate designs may pose a challenge, modifying your own plates encourages creativity and precision. Though the instruction manual is in Japanese, visual aids simplify the assembly process into a rewarding experience.
