Advisors Dr. Jeff Heys and Fred Peña, Arizona State University
Design Development
Final Design
Sparky 1
 Battery made from zinc plated nails (anode) in zinc sulfate
solution and copper (cathode) in copper sulfate solution with
a salt bridge made from sodium chloride soaked sponges
 Battery case was prepared from Plexiglas with 10 cells per
case
 Cases are stackable to allow for the use of multiple cases
Figure 2: Stacked Battery Cases
Sparky 3
 9V, 0.1 amp motor used to
propel car
 Gears attached to both motor
and front axle
Battery
 Made from galvanized steel
(zinc) and copper plates
 Galvanized steel body
 CD casing
 Paper towel sheets soaked in
lemon juice were placed in
between metal plates to act as
an electrolyte
Figure 7: Bryan Testing
the Car
 Each cell was made from one
zinc plate and one copper plate
with a soaked paper towel
placed in between

Complications
Timing Reaction
 Did not achieve high enough current or voltage
 Hydrochloric acid of varying
concentration is used to dissolve a
magnesium strip
Sparky 2
 The strength of the hydrochloric
acid is determined by time it takes
car to travel the required distance
 Battery made from zinc plated nails (anode) in zinc sulfate
solution and copper nails (cathode) in copper sulfate solution
with a salt bridge made from agar and sodium chloride
 Each cell was created in plastic tubing to reduce size and
weight
 Agar salt bridge was used to maximize ion flow, creating
improved current and voltage
Figure 5: Timing Reaction
Case
 Magnesium strip is wired within the
circuit and acts like a switch,
shutting the motor off
 Still could not achieve high
enough current to propel the
motor using a reasonable
number of cells
