Team Vision for Subsystem Level Build & Test Phase

During this phase, the team's main focus was on beginning testing. We found out right away that our original design was not capable of withstanding the rigors of the tests. We dealt with leaks, flooded plants, dry plants, and overall failure. We redesigned the system, using buckets instead of milk jugs and had extremely limited success. Nearly all of the plants died on account of the water delivery system. The dripping system was too uncontrollable to work. Next we decided on a wick system to deliver the water/nutrients to the plants. This is currently going through testing and has potential to be a success.

Test Requirements and Data Collection

Factors now tested in benchtop include:

The data collection and experiment guide can be found here. The document is updated weekly from data collected from google forms during maintenance.

Nutrient levels had to be adjusted due to testing constraints so all plants are receiving 5ml/gallon currently of each nutrient part. The nutrients used are General Hydroponics 3-part Flora series consisting of FloraGro, FloraMicro, and FloraBloom.

The original nutrient plan and an more detailed explanation of the nutrients can be found here for anyone looking to implement two nutrient levels for future testing.

Test Results Summary:LED Testing

So far this phase testing has begun on the lighting subsystem.

Lighting Test: Dimmer System

Through testing it was discovered that the original component purchased would not work due to their mechanical nature and new parts would have to be purchased to work with our system. A summary of the testing and process of choosing the lighting can be found here

Updated Lighting System: Dimmers

A decision was made to update the current lighting system to a basic system (explained in document) based on original testing, giving us the ability to alter the brightness of the lights. A document explaining the details of this process with all possible lighting options can be found here

Sensor Subsystem Decision

Sensors did not fit into the scope of this project due to complexity, budget, and time. For this reason, it was decided sensor would not be a subsystem in MSD II. If it is decided in future MSD teams to implement a sensor system information collected can be found the Detailed Design section of the Edge page.

The project will proceed with four major subsystems: lighting, aeroponics, motor, and trays.

Surculus Build Update

The Surculus has been delivered to RIT. Assembling has been placed on hold due to a missing part. The problem and solution is explained in the Problem Track document below.
