Drink Selection
Searching For Drinks:
From the “Search” tab it is
possible to search existing drink
recipes by limiting results to drink
names that including the inputted
text.
Printed Circuit Board (PCB)
The PCB interacts directly with the
software through the parallel port on the
PC. It implements its digital state
machine logic through the use of Gate
Array Logic Chips (GAL). The output
voltage of the GAL chips are then
buffered and connected to a series of
solenoid valves which are driven by
Darlington circuits. Due to the nature of
these solenoid valves, fly-back diodes
are used to compensate for sudden
voltage spikes.

Quick Selection:
From the “Top Drinks” tab users can
quickly select a drink based upon
previous users’ selections. These
lists include the 10 most requested
and the last 10 created.

The Automatic Drink Mixer is designed to produce various
mixed drinks through a computer controlled automated
dispensing system. It has a robust user interface and
ingredient monitoring system. During maximum operation a
total of 32 different ingredients can be made available.

Graphical User Interface
From the “Browse” tab users can
easily find drinks that contain a
combination of particular
ingredients. Where the ingredients
are limited by their classifications.

Mechanics (Plumbing)
Solenoid Valves
Creating Custom Drinks:
A set of two solenoid valves are used
for the metering of the liquid during
the dispensing process. A length of
tubing is placed between the two
valves and by alternating one open
and one closed, an exact amount of
liquid is dispensed every time.
From the “Custom” tab user
can create their own drink
recipe by choosing the
ingredients that they desire.
They also have the option to
save this recipe for future
use.

Various sized flexible vinyl
tubing provides transportation
and flow rate for liquid. Where
plastic fittings are used to
interconnect the different
components in the system. At
the apex of the system, air relief
valves are used to bleed out
unwanted air in the lines.
