T.A.B./Project Motivation

Origin

• Amherst Brewing Company

• Bartender makes no tips for table ordered drinks - inefficient

Goals

• Decrease drink wait time for seated patrons

• Increase bartender efficiency

• Easy to operate

• Production at an affordable price

• Should NOT replace the Bartender

Target Audience

• Restaurants / Pubs

T.A.B./Project Motivation Cont.

Marketability

• Scalable Production

• Huge Market i.e., EVERY restaurant/pub where the bartender makes table ordered mixed drinks

• Huge market means potential for large profit

• Restaurants already use POS terminals – no learning curve

• Automated Liquor Dispensers exist, but nothing that actually mixes the drink and dispenses it…

Plan of Attack

Break Design into Components

• Software – Java

• Hardware – PIC Assembly

• Electromechanical

1. Allows for individual focus and encourages peer interaction

2. Time management

3. Top-Down approach

• Small changes in pressure = large liquid flow rate changes

• Time vs. Volume and Speed – Controllability

• Fluid Timing

Communication

POS Computer – PIC Microcontroller

• RS-232

• Byte driven operations

• Bi-directional

PIC Microcontroller – Mixing Apparatus

• PIC Output Expansion Chips

• PUMP ID – Ready PIC for Pump ID #

• PID # - Pump ID #

• QUANTITY – Ready PIC for quantity information

• QNUM – Number of ¼ ounce increments

• MIXING ID – Ready PIC for mixing information

• MIXINFO – Mixing specifications

• END – End new drink request

START PUMP ID PID # QUANTITY QNUM MIXING ID MIXINFO END

Database Design

Database Schema

• Utilizes Java StringTokenizer

• Easily updatable

• Intuitive

Entry Format

1 Drink Name : Ingredient.1 Q_Number Ingredient.2 Q_Number

Drink ID, Drink Name, :, Ingredient, Quantity, Ingredient...

Example Entries

1 Rum and Coke : Rum 8 Coke 20

2 Gin and Tonic : Gin 4 Tonic 20

3 Iced Coffee : Coffee 20

Safety Information

FDA Requirements

• All liquid tubing/connections FDA tested/certified

• FLO-JET Pumps used by Coca-Cola for soda dispensers

• ASCO Valves – Often used in Bio-Med industry - isolated

• CO2 Does not interact with liquid, but is Med. Certified

Safety is PARAMOUNT

• Limiting factor

• Expensive
