Fabrication Process

• We decided to connect the servo motor with the liquid timer using gears. Despite the time constraint, we proceeded with two 3D print prototypes to make adjustments midway. While looking for images to demonstrate the connection where users can bring a magic wand close to a magnet sensor, I edited images of Snoopy and Woodstock that Sherry likes.

• We devised a laser-cut semi-transparent acrylic cut to easily connect the gears. As a result, although we regretted having to increase the size in terms of design, it was very helpful for the connection, compared to the liquid clock.

• Regarding the gears, we noticed a slight difference in the spacing between the servo and bevel gears, as well as the vertical gears. We made adjustments in the second prototype to maintain a clearance of about 0.7 mm, which significantly improved the toothed parts.

• We planned to place the initial NeoPixels behind the liquid timer to create an ambient light effect. However, during the production process, we encountered interference between the wires of the NeoPixels and the frame of the liquid clock, which rotates 180 degrees, and realized that the gears were not sufficiently solid. Therefore, we modified the design to illuminate the character (Snoopy) in the direction of the light.
