I love Rum and Coke. It's my favorite cocktail by far. But I never make them at home because I always seem to make them too strong or too weak. That is the inspiration for my final project: The MakerBar!

The MakerBar is a countertop fountain dispenser that automatically adds the right amount of rum depending on how much cola you desire (up to 8 oz). It is contained in a laser-cut acrylic enclosure held together with 3D-printed PETG fasteners. Everything is controled using an ATTiny on a custom-milled board.

I took extra care to ensure everything is as food-safe as I could feasibly manage.

To view the planning and goals of my project, please see Applications and Implications :)

I split the documentation into sections based on the different fabrication processes. They are as follows: Design, 3D Printing, Laser Cutting, Circuit Design & Milling, Assembly.
