This is going to be a pretty boring webpage with few images as I am still working on much of the design.
Here is a preview of my Fusion Design which is close to what the final product will look like. I am currently working on designing the assembly mechanics.
What will it [my final project] do?
My final project is a drink dispenser to make the perfect Rum and Coke using a ratio of 6 ounces of Coca-Cola and 2 ounces of Bacardi Rum. A bowl of limes will be provided.
I am still wotking out the details of how it will be dispensed. I am considering using a screen and knob similar to Prusa 3D printer, but I may just use a button-press.
Who's done what beforehand?
I have found an instructables for someone who made a custom fountain-drink dispenser using the same pumps that I am using. The design, however, is very different.
I am basically designing everything from scratch: the enclosure, wiring, circuitry, controller, etc. I will not be designing the components such as the pumps, buttons, and LED strips.
What materials and components will be used and where will they come from?
The parts list, along with cost and where they were purchased/aquired is here.

What parts and systems will be made?
Enclosure
Interior Guides for Wires, Tubing, and Pumps
Main Controller Board
Spill Catcher
Lime Bowl and Tongs
What processes will be used?
Laser Cutting the Acrylic for Enclosure
3D Printing Spill Catcher, Internal Fasteners, Wire / Tubing Guides, Pump Holder, and Probably More
Milling Cutom Controller Board
Embedded Programming for Controller
What questions need to be answered?
Is the ATtiny1616 the right chip for this?
Can the ATtiny handle 6V?
How do I make 2 pumps go at once, one of them slower than the other?
How large do I want this? Right now it is 300 mm x 200 mm.
Will my custom fasteners work?
Will this work with Pepsi?
How will it be evaluated?
If I am able to make a single, delicious Rum and Coke before everything breaks, I will be happy.
Your project should incorporate:
2D and 3D Design: I will be using Fusion 360 and Adobe Illustrator to design everything
Additive and Subtractive Fabrication Processes: 3D Printing for addative, Laser Cutting and Milling for subtractive
Electronics Design and Production: KiCAD to design controller board and Roland / MODs to mill it
Embedded Microcontroller Interfacing and Programming: ATtiny1616 to control everything
System Integration and Packaging: The enclosure is going to be transparent, so I want everything to look tidy
