Item Iot Batch MixingSkid(2023-05-05) Thang, Siang; Weissbach, Robert; Goodman, David WayneThis report is a summary of the IoT Batch Mixing Skid Upgrade team’s senior design project to meet the requirements provided by Dr. Elizabeth Freije and Dr. Phil Pash. The request was to upgrade an existing tank instrumentation system that measures flow, temperature, level, and pressure within the system to an IoT capable instrumentation system. The team planned to replace current Endress and Hauser components with components that could communicate wirelessly. The report consists of the objective of the project, the design of the project, and components/devices that will be replaced. The focus of the report is to reveal our design, the new process of the system, how it functions, and the new devices and components that we replaced and tested for this project.Item Multipurpose Combined Power Supply, Signal Generator, & Oscilloscope(2023-05-03) Thawn, Thang; Joseph, Mandorlini; Sung, Mang; Izadian, AfshinProject Csignal was initiated during the COVID-19 pandemic when in-person laboratory sessions were not possible due to the restrictions imposed to curb the spread of the virus. At the time students couldn’t come to campus for the lab. The objective of the project was to design and develop a device (termed Csignal), which could be used by the students for laboratory exercises at their homes. Csignal is essentially an integration of three essential pieces of equipment used in the laboratory, namely, a power supply, a function generator, and an oscilloscope. These three pieces of equipment are what students used at the lab to power and test their circuits. The primary aim of this project is to create a cost-effective version of these three devices, which can be combined into a single compact component. While the Csignal will not offer the same level of functionality as the main devices in the laboratory, it will be adequate to suffice the students' needs for conducting laboratory experiments from their homes. Moreover, the Csignal will be compact and portable, making it more convenient for the students to use and store.Item Senior Design Project Report Whole House Ventilation System(2023-05) Rios-Jauregui, Anthony; Herrera Sandoval, Jennifer; Chaiyasit, Matt; Weissbach, Robert; Lin, William; Goodman, DavidThe Whole House Ventilation System was created out of the sponsor’s need to have cleaner air within their home. The system will accommodate a Ranch-style, 2000 sq ft home located in Indianapolis. A microcontroller will be used to control the fan speed and make decisions based on sensor data. Other specifications include having the fan produce noise below 65 dB, physical controls for fan speed and power, and having an Android app to view sensor data. The four system tests we conducted verified power, sensor functionality, and Auto/Manual functionality. All four tests passed. The final system met the majority of the customer’s needs. We recommend a PCB board reprint as some holes do not have pads.Item Themed Entertainment Impact Adapter Senior Design Final Report(2023-05-03) Landis, George; Freeh, Ryan; Pash, PhillipThis project is what is known as the Themed Entertainment Impact Adapter. The issue is to improve a system already in place by creating a new detection system that will allow a guest to interact with set pieces with a physical hit and have communication back to the host. The sponsor, IFM Interactive, is wanting a custom Printed Circuit Board (PCB) that will be housed in a watertight plastic case specified by the sponsor. The device is a detection system that uses an accelerometer to notify another unit that the device detects a spike in the z-axis direction. The specifications that needed to be met that were given by the sponsor are as follows, • Printed circuit board-based design that mounts inside of an IP rated enclosure selected and provided by the customer. • Enclosure penetrations must retain environmental (IP) ratings such that the device could be installed outdoors. • Capable of operating in temperatures up to 80C. • Accept 5VDC for power. • Communicate via half-duplex asynchronous UART over RS-485. • Connect to upstream power and RS-485 data via a single 4 pole M8 connector. • Detects forces applied via internal accelerometer. • Implements communication protocol specified by the customer. • Create ~6 fully working units by April. The test plan is to test on a similar board using an RP2040. We will want to make sure that it sends a signal using UART over RS-485 to a computer emulating the host machine. The results have been successful in testing. There have been issues with the actual device that are minor fixes in the software design than the hardware. The final system will meet the standards from the sponsor. Some recommendations on improvements would be a better implementation of the hardware. Thus, there is just a bit more of editing on the layout. Moving the USB-C to another open way to make way for the port that will be drilled out of the unit to allow for access to power and data to the upstream unit.Item INVERTED PENDULUM ON A CART SENIOR DESIGN PROJECT REPORT(2023-05-03) Vergara, Sergio; Aljishi, Hawra; Logan, Dylan; Freije, Elizabeth; Weissbach, Robert; Pash, Phil; Lin, William; Stephens, CraigThe purpose of this project is to design and build an inverted pendulum system from an existing nonworking inverted pendulum system for the Engineering and Technology Department. Once completed, this system will be used for educational purposes for future students to observe code, understand the design, and study the physics of the system. We have tested our system numerous times with a variety of different device configurations so as to perfect the system. We have clearly labeled and documented everything, which will help when students are working on the system in the future. This document contains but is not limited to the information for our scope, design decisions, schematics, design blocks, bill of materials, and code. This was designed to show the finalized overview of our systems and what we presented at the end of the semester.Item Solar Decathlon Capstone(2023-04-28) Grote, Whitten, Sifiso, Christian Moyo, DeLaRosa; Izadian, Afshin; Stephens, Craig; Nickolson, DarrellThe Electrical Engineering Technology Capstone team worked alongside the interior design team to design a building that meets Net Zero energy requirements for the National Renewable Energy Laboratory's Solar Decathlon competition in the Spring of 2023Item Electronic Tabletop Miniatures Game(2023-05-05) Mahaffey, Nikolas; Freije, Elizabeth; Craig, Stephens; Mahaffey, Nikolas; Masheck, Charles; Dohner, JamesThe purpose of this project is to create an Electronic Tabletop Miniatures Game that offers an electronic and computerized element to traditional existing games like Warhammer 40K, Dungeons and Dragons, and others. The gameboard must be expandable to allow for large scale games, which is achieved through the ability of the PCBs to be plugged into one another to increase the gameplay area. Small PCBs on the individual game pieces or tokens store the information and attributes of each piece, allowing them to be placed onto the gameboard to communicate their position, identity, and attributes. The rule keeper device, acting as the central computer, manages gameplay and enforces rules while also having the ability to substantiate gameplay on the physical board through the use of individually addressable LEDs. This project will provide players with an exciting and immersive gaming experience while offering the added convenience of a computerized interface that tracks and manages gameplay.Item Cape of Wonders Club(2022-08-07) Alyami, Bandar; Alghamdi, Mohammed; Weissbach, Robert; Lin, William; Pash, Phil; Freije, ElizabethThis project aims to create a cape of wonders club that includes technologies. This cape is a square piece of fabric material with electronics inside it, including a blood alcohol sensor, noise sensor, user input screen, and visual display. The electronics are integrated using a microcontroller, which acts as a brain to operate each electronic device. Two battery banks are built to power the electronics and ensure that the project can run for at least 6 hours. The project's two sensors are designed to produce readings. The blood alcohol sensor indicates the level of ethanol in the cape user's blood and displays the results to determine whether the user is below the legal limit or not. The noise sensor reads the music sound in the nightclub and converts it into patterns, which are then shown on the visual display. The visual display, on the other hand, will function as an output, displaying the music patterns. Furthermore, the visual display will exhibit emojis and shapes. The user input screen will allow the user to choose amongst Emojis, shapes, and patterns to be represented in the visual display. The developers of the project will work on building, coding, soldering, and testing these electronics to ensure that they function properly. They will ensure that this club cape is well-made and that it seems fashionable and appealing to the customers of the nightclub cape.Item Magnetic Levitation System: Senior Project Report(2021-05-05) Martin, Cody A.; Snyder, Zachary S.; Weissbach, Robert S.This magnetic levitation system is designed to levitate a steel ball using an electromagnet suspended above it. The project was sponsored by Dr. Robert Weissbach, Chair of the Department of Engineering Technology at the Purdue School of Engineering Technology at IUPUI. This project was undertaken by undergraduate students Cody Martin and Zachary Snyder. This magnetic levitation system uses closed loop control with a digital controller to accomplish levitation.Item Smart Seat Car Seat(2021-04-26) Sims, Donte; Hall, Evan; Diallo, Houssainatou; Weissbach, Robert; Goodman, David; Pash, PhilA solution to children being left and forgotten in their car seats while parents/guardians take a brief step away from the vehicle with the intent of returning shortly. The Smart Seat uses a temperature sensor to keep track of the interior temperature of the vehicle, an occupancy sensor to detect front seat presence for childcare, 2 force sensitive resistors (FSR) to detect child presence in the car seat, and a strobe light to alert the public when limits have been exceeded that a child has been left unattended. A raspberry pi is used as the brains of the operation. It has a feature to send text messages to the owner’s cell phone regarding child safety and to alert authorities.
