Bar-Mixvah:
The Automated Bartender
Bar-Mixvah was a initially a class project; build a system with two or more inputs, two or more outputs, and an interrupt or A/D conversion. But I wanted to build something more than just a few buttons, I wanted to make something I could use and keep. That's when I began to CAD and design the housing for Bar-Mixvah. By using a CNC and a laser cutter, I was able to build the housing out of wood, acrylic, and ABS. Then I wired the circuit inside the housing. The circuit is controlled by an Atmega328p AVR chip, and runs off of a 12V power supply. The video below shows Bar-Mixvah in action!
