We began by receiving a task and selecting an image from a set of options. After choosing the image, we collectively brainstormed to explore the various interpretations of the chosen object. Eventually, we settled on the concept of a fountain. Through thorough discussion and a closer examination of the image, we dissected each component of the structure, assigning specific functionalities.
Our envisioned design included two wooden bases with a plexiglass panel in the center. The plan involved incorporating a projection element, achieved by projecting images through the plexiglass. To infuse creativity and fun, we decided to introduce a water element. Each team member individually sketched ideas, and upon choosing the most promising draft, we created a final sketch and proceeded with a 3D modeling. Concurrently, we researched the functional aspects and materials required for the construction.
In the final design, the structure's height prompted a revision to the initial plan of using two plexiglass panels due to budget constraints. Instead, we opted for a single, thicker plexiglass panel. We then delved into the dynamics of water flow onto the plexiglass, considering its source, trajectory, and destination. A box within the lower base was designated to collect and reuse water, with a hose facilitating the transfer from the box to the top of the plexiglass.
Materials exploration commenced with a search for sustainable plexiglass, leading us to repurpose a piece acquired during the COVID period. Other materials, such as iron and a large bottle, were salvaged from a skip to align with our commitment to a recyclable structure. The remaining items were sourced from various places, including a teammate's home.
Following a trip to Nicosia to assemble the wooden bases, we decided to place the base only below the plexiglass to avoid excessive weight. To conceal the hose, we ingeniously incorporated it within the iron structure. Upon returning, we initiated the coding process, facing challenges and conducting extensive online research to achieve the desired outcome.
During construction, we encountered the need to resize the irons, yet lacking a means to cut them, we adapted by securing them together with corners and bolts to match the intended shape. The hose was slided through the inside of the irons, and the plexiglass required multiple adjustments to align with the height and size of the irons. We strategically punctured the hose to ensure even water distribution across the plexiglass, sealing the excess opening with a zip tie.
Assembling all components, we tested the system to verify that it met our expectations, successfully achieving the desired results after multiple attempts.
