Based on the second model, a new design for the drink mixer was developed. Prototype 3 is inspired by a coffee machine and has a similar shape. The drink mixer will have 6 bottles, three different alcohols and three different mixers. The main structure will be mounted on a base which will have the alcohol and mixer bottles on both sides of the main structure as it can be seen in Figure 4. Electronics, including the peristaltic pumps and the power supply, will be stored inside of the structure to make it more aesthetic. Users will be able to choose their desired drink by using the touch screen located on the front face of the main structure.

Having this new model, the components that will be needed could be determined. These are listed in the components section of the website. During this week the bill of materials (BOM) was a work in progress as the team took some time to explore the different models of the components we needed. The focus was both on dimensions as well as voltage needed.
