This project is a jewelry storage and display for my girlfriend, with an emphasis on displaying her earrings. Her current jewelry storage consists of a single drawer in a small box on her bedside table, and after watching her dig through a small mound of tangled earrings and necklaces I saw a need for something new.

The base has two removable drawers, and the blank part on the right houses the Arduino, the sensor, and the motor. The top part is a gear and chain system that has a piece of light fabric stretched around the vertical black pieces. The motor is controlled by an distance sensor on the lower right side and as the motor turns, it spins the whole thing like a carousel and allows her to store, display, and then access her earrings by hanging them on the fabric.

For many of my recent projects, I have attempted to design them so that they can be constructed almost entirely from laser-cut wood and small 3D printed parts, and this one is my best design yet. I really enjoyed working within the constraints of 0.19 in thick, flat materials, and it helped me think creatively on how to assemble the whole thing together.

The chain was designed by myself in Fusion 360, and the gears were designed in a software that I acquired, specifically designed for making gear, chain, and sprocket systems. 

This is the first function prototype for the chain and gear system. I was very pleased with the result and it worked very smoothly after some sanding and minor adjustments.

Here is the initial form prototype. The top half and bottom half were made separately and only resting on top of one another without any adhesion. 

The final project was painted entirely black and used almost an entire can of spraypaint. Here is some of the pieces drying on the rack and later laid out in preparation for assembly.

Finally, here is the storyboard video featuring none other than the intended user!
