The materials came in and final construction was finished today. The tests conducted show that CO2 was absorbed. Some results showed a minute change while others showed more noticeable changes. We shall be concluding our project by practicing our presentation and sprucing up our final report.
The prototype of the filter
Week 9 Updates: 5/27/13
After consideration, we are planning on using ABS over acrylic as it is cheaper and of similar qualities for the job. We have ordered it and are just waiting on it to come in the mail. Then we can machine it and construct our final deliverable.
To-Do List:
- Prepare final report and presentation
- Construct the final model and finish tests
Week 8 Updates: 5/20/13
Some necessary materials have yet to be received so progress is still hindered right now.
To-Do List:
- Finish construction
- Finalize filter component design
Week 7 Updates: 5/13/13
Some of the materials purchased have not been delivered yet. Unfortunately, because of this, construction has been halted thus far.
To-Do List:
- Construct the full filter
- Test the filter component and optimize
Week 6 Updates: 5/5/13
Hess labs will be allowing us to cut out our acrylic frame from their extra 1/4" thick sheets that they have. We are currently waiting on the materials to come in and are researching the wiring involved for our project, namely between the power supply and computer fans.

Additional supplies to purchase:
- Acryllic glue
- Wires
- Power supply
To-Do List:
- Start constructing frame
- Create the filter screens
Week 5 Updates: 4/29/13
As of now, we have everything either ordered or already here. From the AutoCAD files, we should be able to have Hess Labs cut out the pieces of acryllic we need. Once we have that, we shall be constructing the actual filter components. We plan on implementing 3 of these filter components in which a layer of activated carbon will be encased in 2 window screens and then placed inside the acryllic frame. We are in the process of doing research on the properties of activated carbon and the type of screen we should use.
The screen we had decided to order
To-Do List:
- Start making the acryllic frame using the laser printer
- Decide on filter screen material
Week 4 Updates: 4/22/13
Thus far, the only materials we have are computer fans. When we visited Hess Labs, there were classes in session so the machines were not available at that time. The labs might have spare materials, specifically acryllic, for us to use.

To-Do List:
- Research alternative ways to detect CO2
- For the sake of budget, cheaper alternatives would be ideal
- Talk to the environmental science/engineering, biology, and chemistry department regarding CO2 sensors
- To see if the departments have CO2 sensors for our use
- Revisit Hess Lab regarding materials and machines
- Buy activated carbon
- Buy dry ice
- Research wiring
- Look into screens to use for containing the activated carbon
Week 3 Updates: 4/14/14
We ordered computer fans for our filter.
To-Do List:
- Find out from Hess Lab about the machines available
- Find out about availability of Acryllic
- Make AutoCAD drawings of the filter
- Research wiring
Week 2 Updates: 4/8/13
Thus far, the group has created an initial design for the filter and has formulated a list of the materials necessary.
To make the filter, we shall need:
- Table Saw, to cut the plexiglass.
- Drill, to help put together the components to form one piece.
- Accrylic, the casing of the filter
- Sponge, to absorb carbon dioxide
- Carbon Dioxide Absorbant
- Dry Ice, to create the carbon dioxide for the presentation
- Fans, to push the carbon dioxide into and through the filter
- Wires, to connect to the fans
- Power supply, to provide the power for the filter’s fans
- Carbon Dioxide Detector, to show a decrease in carbon dioxide for the presentation
We projected our costs for this project as well:
