Project Status Update – Air Filter

Summary:

Our Biodesign project will be a filter that is placed on top of roofs and placed in air conditioning systems. The filter will be made from a compound of coffee grounds and potassium hydroxide that has been heated and then formed into a usable shape. The compound it able to absorb both methane and CO2 exceptionally well. Once the compound has been exhausted and absorbed the material can be used as a fuel source that burns much more cleanly than typical fossil fuels.

Pictures

We have currently are awaiting some of our materials for the project but our two main components are coffee grounds and potassium hydroxide.

Code:

We currently have no code but we plan to have the code output information from a methane sensor for the user.  It will allow the user to know how much methane is in the air and when the filter has filled.

Timeline:

  1. (This week) For our project, we wish to make the compound in real life

2. (Nest week) Then place the compound into an existing air filter and have it absorb the gas

3.  (Last week) Once the filter is working we will make sensor to go along with it so that is it much easier for the public to use it

Bio-luminescence Update

This prototype shown below illustrates the bio-luminescent system will illuminate when the algae are agitated. The prototype consists of UV sensitive liquid and a servo motor acts a generalized form of actuation to disturb the system.

The prototype suggests that regardless of final concept, there is some consideration that need to be accounted for when completing the system. For example. a form of actuation that can be performed to a non-moisture form of algae. Other considerations would be to maximize sensing/actuation that reacts to a users input. Creating the notion of object-user receptive interactions.

Depending upon whether or not an algae culture in possession is able to regain its luminescent qualities, will determine time tables for testing an integrated system for dry actuation. But regardless there will be an iteration that requires a moisture dependent system.

Timeline:

4/12 – Present prototype, discuss design for final iteration
4/17 – Divide algae culture, test dry system, design fabrication for project
4/19 – Create code and electronics for the interactive system
4/24 – Putting system together with new culture in place
4/26 – Final touch-ups on project
4/28 – Showcase

Project Update

Our project in its current form is about air quality sensing. We want to cheaply and accurately be able to know whats in the air around you.

This currently is what we have set up wise. We wanted to make sure that the sensor that we have worked before building something for it. We plan to make some 3D printed structure to house everything for easy transport. Sadly our sensor that we were using isn’t what we are looking for. It has the capicity to detect more than one gas, but not tell the difference between them. The output range can tell us what gas is present, but many of the ranges overlap.

#include <SoftwareSerial.h>

SoftwareSerial lcd = SoftwareSerial(2,4);

void setup() {
Serial.begin(9600);
lcd.begin(9600);

lcd.write(0xFE);
lcd.write(0xD0);
lcd.write((uint8_t)0);
lcd.write((uint8_t)0);
lcd.write((uint8_t)255);
delay(10);

}

void loop() {
int reading = analogRead(A0);
Serial.println(reading);

lcd.write(0xFE);
lcd.write(0x58);

lcd.print(reading);

delay(200);

 

Timeline:

4/12 – present

4/17 – start printing the model and get additional sensors

4/19 – add additional code for sensors

4/24 – refinement

Roles :

Anthony – 3D modeling and coding

Chris – sensor research and coding

Jackson – project and conceptual development

 

DIY Seed Kit Update

Project by Ziyi, Cody, Inez, and Erin

Our project is about creating a cheap and easy to replicate seed planting kit for the everyday person meant to maintain different plants in different, sometimes harsh environments. It does this by balancing pH and moisture with the inclusion of biodegradable kombucha scoby.

Here is our current setup. We laser cut a box with an open top- four of the sides are wood, the fifth is a type of plastic, allowing us to hopefully view the kit once it’s planted. We had to use duct tape to plug in the holes. We are using small yet biodegradable tea bags (in the green package) to hold everything. The smelly scoby is in the glass jar for now, waiting to be minced and placed in the bag. We are waiting on the soil to be delivered in order to put the whole bag together. Tomatoes were the fastest growing, most acidic thing we could find, so they will be the seeds we place in our test run.

This is a section of the code we are using. It is the soil sensing example that we have used previously in our class. We are currently trying to work out a cheaper method to the pH sensor to keep the DIY feel, so we will most likely not need pH code but perhaps color sensing code?

Our timeline is as follows:

April 12: Prepare tea bag demo and plant the first bag

April 17: Discuss change in code and price out alternative

April 19: Set up contents for a second, ready to create display

April 24: Pretty up display and test Arduino setup

April 26: Present final project

Our group is fairly well rounded, with everyone contributing fairly similarly. Cody is an exception, with him focusing on coding. Inez and Ziyi are taking care of the scoby and visual setup, while Erin is documenting, posting, and helping all around.

 

Project status update

Post an update about the progress of your final project. Include the following:

  • Quick summary of what your project is about (1-2 sentences)
  • A picture and description of what you have implemented so far
  • Code snapshot (upload your current code and briefly describe what it does)
  • A timeline and specific objects for what you hope to accomplish by April 19 and April 26 (showcase/deadline!) State how each member of the group will contribute to achieving these milestones.

Post your project update on the class blog under the “status update” category. These are due before class on Wednesday. Bring whatever you’ve made to class on Wednesday for an in-class critique.

This assignment is worth 4 points
1 point for project summary
1 point for a picture, code snapshot, and description of what you have implemented so far
1 point for updated project timeline and group responsibilities
1 point for bringing your prototype to class
