DC ELECTRIC TORQUE WRENCH
PROJECT IN JOHN DEERE WATERLOO
WORKS
Presenter: Loren Leusink
Faculty Advisor: Dr. R. Pecen
Sponsor/Industry Supervisor: Brenda
Dudley, Donald Swanson, John Deere
Waterloo Works.
Time: 3:00-3:20 pm
Objectives include; (1) install one Cleco
electric torque wrench for tightening cab
mount bolts, (2) implement the torque
wrench with the line automation, (3)
mistake proof the cab drop zone to prevent
any cab from dropping on the wrench, (4)
collect torque data on each tractor for
quality purposes. The flat-top conveyor is
stopped if either one or both of the Cleco
torque wrenches do not torque a joint to
specifications. Some possible fault
conditions are: high torque, low torque,
high angle, low angle, or the
tool was not used on the joint. The rundown data is stored in a database and
tied to the tractor serial number for Quality
Engineers to work with.
UPS-Uninterruptible Power Supply
Design
Presenters: Jared Seltrecht & Dane
Oelmann
Faculty Advisor: Dr. R. Pecen
Time: 3:20-3:40 pm
This project includes design and
implementation of a 500 W UPS circuit
that includes a custom-design charger, a
voltage controller, a comparator, a power
amplifier, an inverter and a rectifier
circuits. A UPS is basically a backup
battery for loads like computer, TV, or any
load that end users don’t want to
experience a power interruption. Project
combines testing and implementing power
converting methods along with digital and
analog monitoring and recording
equipment. UPS provides electricity to
certain number of loads when a power
interruption occurs.
ECO-FRIENDLY ZERO-EMISSION
LAWN MOWER “”

With the growing concern of air pollution,
environmental impacts and
growing demand on fossil fuels, an ecofriendly lawn mower is developed at UNI.
Operating a gas mower for 1 hr produces
the same pollution as driving
a car 1300 miles. Each weekend, about 54
Million Americans mow their lawns,
using 800 M gallons of gas per year. An
EPA study found that approximately 9 %
of some types of air pollutants nationwide
come from lawn & garden equipment small
engines. This project included converting a
conventional lawn mower to a solar
powered unique machine called
“UNIMow” by installing a PMDC motor,
charging circuit, deep-cycle batteries, solar
PV panels, switching, monitoring and
safety circuits. Testing and demonstration
efforts show that UNIMow may be a future
lawnmower of our backyards for ecofriendly and more quite environment.
The goal of this project is to develop a zero
emission golf car that exhibits the same or
better performance than its fossil fuel
powered equivalent. With the results of
testing, we hope to show that H-powered
vehicles can prove viable sources of
transportation that someday they could
truly be replacement to their fossil-fueled
counterparts. For this project it is
unreasonable to build a full-scale vehicle
with the resources we have, so we hope to
prove that our system viability in a scaled
fashion, hence why we are developing our
project on a gulf cart chassis. System
modules include a 500 Watt fuel cell to
produce the electricity stored in batteries, a
throttle with a "hall effect sensor", a
controller, and a golf cart chassis.
HYBRID BOAT DESIGN &
IMPLEMENTATION
(This is not the solar eBoat Project)
Presenters: Michael Boomer and Ben
Wagner

Time: 4:20-4:40 pm
The increasing cost of fuel has lead to
renewed interest in efficient and
environmentally friendly watercraft.
This has also has changed the way that
people use their boats. With prices
hovering around $3/gallon last
summer, driving to the beach and
casting off is becoming a luxury.
Our objective is to design and construct
a hybrid drive train system to power a
medium sized pleasure boat. This
hybrid system will use a gas or diesel
engine powering a generator to produce
energy in the form of electricity. The
electricity is then stored in a battery
bank until it can be used at much more
efficient levels. This is especially
efficient because the generator will be
running at peak efficiency at a
supposed constant load, maximizing
fuel efficiency. An electric motor is
more efficient than using an internal
combustion engine alone, even if the
engine is allowed to run constantly at
peak efficiency.

AC/DC Conversion for Hybrid Boat Project.
Two other senior projects; (1) design and
implementation of a PWM based speed
controller for 1 HP AC motor by Yao and
Hussain, and (2) Ear Phone Design by
Seth Reid are extended to May session for
completion, testing and data collection.
