What is a glow discharge chamber?
• Uses high voltage passed from an electrode
to a grounded specimen
• Generates plasma on the grounded
specimen
• Used to create non-thermal plasma by an
electrical field
• Non-thermal plasma is much cheaper than
thermal & more practical in manufacturing
purposes

Sponsor and Problem• Csar Ornelas
– Contractor
• Problems with Debris Clean
up
– Lengthy process
– By hand or with hand tools
– Hand tools are difficult to
handle the debris
• Desired Solution
– A way to secure debris to a
shovel in order to greatly
decrease clean up time

Survey Results
The survey has answered some of our design questions so that
we are now able to start some simple sketches. We will be designing
a universal adapter with a simple mechanism to fit on
many different shovels.

Problem
•Drinkable clean water is a limited resource
•4000 children die each and every day from consuming
contaminated water
•1.6 billion people live without electricity
•1 billion do not have access to potable water
•5 million die every year
due to drinking non-potable
water and becoming sick

we later discover that gravity fed is not an option with the filters, so we
Modify the design to have a hand pump

Design• Evaporator for Salt desalinization
• Four Filters design to remove microbes and
bacteria's
• Will use plumbing to
connect filters and drain
into container to
prevent growth of bacteria
• Manual Pump later added to
design

Description of Project The main goal of project is to create a fully mobile display
unit that holds our injection molding parts in place, safely.
The goal is to provide the professor with an easy way to
show how the injection molding process works while
letting the audience to view all components and parts.
