    Hydroponic Control System
    (2017-08-05) McNeely, Andrew; Cooney, Elaine
    The goal of this project is to design and construct a hydroponic control system. The control system will process signals from the required inputs and control output devices based on operational criteria. The control system will display the amounts of water and nutrients that need to be added on a daily basis to maintain a proper growing environment. A daily chemical test is required so these readings can be obtained. The desired nutritional specs are provided by Emerald Harvest Nutrient Series Feeding Chart. The system consist of 3 chemicals, Grow, Bloom, and Micro. The ratios of these 3 chemicals change on a weekly basis during the 16 week grow cycle. The system will continuously monitor the humidity of the grow area and cycle a humidifier to maintain the area within certain specs. Since the system is designed to be indoors, a way to control temperature is not needed. The grow lights are designed to supplement natural light and therefore the system needed to be placed near a south facing window. With minimal user interaction, the system should be able to provide adequate grow environment for up to 5 small herbs over an entire grow cycle. After a grow cycle is complete, the system is ready to start all over again.

    Mini Mars Rover
    (2020-12-11) Alanzi, Nafa; Tan, Chad; Walden, Dae’Shaun; Freije, Elizabeth; McNeely, Andrew
    The customer, Andrew McNeely, would like us to construct and design a miniature-sized version of the existing Mars Rover robot. The robot will be controlled through an Android Application that we have designed, that will control the motor movements and command the robot to collect five data points from the environment. What we are given that is out of our scope for operation is an existing robotics kit that we will grab components from, the battery, frame, wheels, and motors. Our In-Scope of operation is to design a buck converter, power supply, and a transistor circuit that will transfer a low voltage output from a higher voltage input, a battery. We also designed a board layout for the motor control and designed a code for the Android Application and the microcontroller.

    Solar Splash Senior Design Project
    (2020-05-05) Binder, Paul; Almogayer, Khaled; Sauer, Matthew; Goodman, David; McNeely, Andrew
    The Solar Splash senior project is the first attempt at creating an entirely solar propelled watercraft. The initial project intent was to design and create a supplement meets the specifications and compete in the competition. With this in mind, a budget approach was taken in order to be able to fund the task at hand. As the project progressed toward the end of the low-level design phase it was evident that the competition would not occur. At the midpoint of the project, the goals and objectives had changed entirely. The new focus was targeted at proving the operation of the systems involved in the watercraft. Having been faced with a new series of objectives and an entirely new scope, the project began to appear doable. The primary focus of the project at this point entirely relied on simulation data and data analysis. The idea was not reinventing the wheel but rather verifying that the wheel rolled. Using the designed propulsion, solar and sensors systems, with the help of a combination of software programs, the idea of a budget solution can be seen. The software used tell the story of the boat that would have been created had the project continued down the original proposed path. As systems were tested and analyzed, they were also adjusted and improved upon. The analysis process consumed a lot of time but acted as a highlighter for all the flaws that the system suffered from. This document introduces the design concepts and schematics of the Solar Splash senior design project. Within are detailed drawings and diagrams for the electrical systems devised for the construction operation of the watercraft. This report is a means of displaying the layout of the final product and how all systems tie together. The report will contain detailed information on not only hardware aspects but also software and how those will bridge together. The report is meant to be in layman’s terms and should be easily interpreted at all levels. The bulk of the information found in the report will be found in the testing sections where analysis of a theoretical boat is done. The motor design, solar design, and fluid dynamic analysis of the boat hull and propeller can be found in their respective section. The innerworkings, testing processes and thoughts behind each decision can also be found in these sections. The document begins with a table of contents identifying each main and subcategory of information. The next page is the document identification, revision history, and lesser known definitions. Following that is the introduction and scope. Specification requirements for the ‘general requirements’, ‘electrical requirements’ and ‘mechanical requirements’ are found on the following page. A system flowchart can be found in the high-level Design along with the design decision matrices for each system. The design portion then begins starting with the System-wide design changes and decisions. The hardware and software designs and schematics follow and cover the proposed schematics and drawings for the system. Cost breakdowns for each individual system are also found in the low-level section. Testing methodologies, results and an explanation of the testing software can be found after the low-level design. A summation of all these testing results is found near the tail of the document. Conclusions, recommendations, and appendixes can be found as the last three sections, respectively.
