Making a Kit-Kat Clock Even Creepier

Becky Stern transforms the iconic Kit-Kat clock into a personalized and dynamic gift for fellow maker Xyla Foxlin. The modification introduces a captivating feature—the Kit-Kat’s eyes now follow movement around the room, adding an element of surprise and humor to the classic timepiece.

To achieve this, Becky severs the connection between the eyes and the tail, which typically move synchronously, and replaces it with a servo horn linked to the eyes. She skillfully drills out the nose to accommodate a camera, connected to a Seeed Grove AI Vision board with a Xiao RP2040 on top. The vision board processes the camera feed to detect movement and direct the servo to adjust the eyes accordingly.

During the soldering process, a small capacitor is accidentally detached from the AI Vision board. Surprisingly, it turns out to be non-essential for the clock’s modified functionality. Becky notes that only one line of code is required to enable the eyes to follow movement, but to enhance the creepiness factor, she refines the code to move the servo in timed increments, creating a more animated and entertaining effect. The build video provides a fascinating look at the transformation process, showcasing Becky’s creativity and technical skills.

The modified Kit-Kat clock not only retains its quirky charm but gains a new dimension of interactivity, making it a thoughtful and unique gift tailored to Xyla’s love for cats and playful humor. Find the components, electronics, and robotics for your own creep project at PiShop!
