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 Design and Build an EVSE(2017-08-07) Micol, Kevin; Cooney, Elaine; Lin, WilliamThis report details how to design and build an electric vehicle charger. The report will follow the SAE J1772 standard and cover the design of the charging and control circuits, the design of the software, building the charger, and testing various aspects of the charger. Schematics, bill of materials, flow diagrams, code, and operation instructions.Item EET Senior Design Project - IMS Dynamic Display(2019-05-05) Elkins, Michael; Boggess, John; Weissbach, Robert; Lin, William; Durkin, Robert J.The Indianapolis Motor Speedway Museum has a display transmission that is still actively used in IndyCar today. The museum wants to incorporate this transmission into an interactive display, so guests of all ages can see internal gears spin as well as see the transmission shift between its gears. This project includes mechanical and electrical engineering technology students working together to mount wire motors and sensors. The transmission will have a user-friendly interface allowing the guests to change gears and to turn the transmission on and off. The transmission will be driven by a 24V DC motor and uses a 24V DC linear actuator to rotate a barrel cam to change the position of the forks, allowing the gears to get shifted up and down. A metal enclosure houses the electrical components that provide power and control to the system. The outcome of this project is a failsafe and robust system that will operate within the IMS Museum while being continually updated.Item ENT SENIOR DESIGN PROJECT REPORT: Jeopardy Game(2020) Graham, Darrel; Kolic, Dominic; Mesfin, Elias; Lin, William; Weissbach, Robert; Freije, ElizabethTo fulfill the needs of our sponsor and the Purdue school of Engineering and Technology, the Jeopardy Game project is a portable and wireless version of the software and electronics for a Jeopardy-style game. This project aims to execute an organized and intuitive screen layout displaying the user customized categories, questions, and contestant names. The game operation is nearly identical to the classic game show. The completed project meets the sponsors requirements and wants. The system including the computer in a protective enclosure, wireless contestant buttons, and wireless host mouse are all able to fit in a standard backup comfortably.Item Home Leak Sensor Final Report: A Kitchen Sink Sensor Used to Detect Water Leaks(2021-05-05) Bonds-Johnson, Jeffrey; Balcazar, Angel; Lin, William; Weissbach, Robert; Pash, Phillip; Goodman, DavidThe home leak sensor project is a smart leak sensor that will detect water leaks under the customer’s kitchen sink. The sensor will alert homeowners with an audible alarm and with an email when there is a leak. The customer is looking for an affordable, fast acting leak detection device that will last at least 6 months before having to replace the batteries, and that is able to collect the leak to minimize clean up. After extensive research, we approached this design focusing on those main points within our decision matrices. We designed a device that will clamp onto the pipes itself allowing us to implement a way to collect the leak and ultimately receive leak detections in under 10 seconds. The longevity of the home leak sensor is accomplished by the microcontroller and batteries we chose. Our microcontroller has sleep mode functionalities and the batteries have a mah rating of 2200. After testing and calculating, we estimate that our home leak sensor will last an average of 935 days before needing to change batteries. Finally, the microcontroller also allows for IOT connections, which we were able to use to connect to the internet and send email notifications to the customer. The home leak sensor is able to detect leaks under 10 seconds, collect ½ cup of water, last an average of 935 days, and sends email notifications to the customer. It passes all of the specifications we tested to, including stability and durability. For future improvements, we may have overdesigned the longevity of the device as the customer only asked to last 6 months. If we were to do this again we would use a mAh rating from our batteries of at most 1000.Item Internet of Things Proof of Concept(2018-12-04) Cucore, Travis; Lin, William; Freije, ElizabethThe EdgeNet platform was conceived of to satisfy graduation requirements and demonstrate a breadth and depth of knowledge capable of working with embedded systems and supporting their integration with larger software platforms. The project is justified as a valid senior design supported by several senior level CpET courses described in the introduction of this report. The EdgeNet IoT platform provides a flexible and brandable platform for connecting consumers and business with devices they wish to monitor or manipulate remotely. Built using industry standard languages and frameworks, consumer facing applications share a common code-base, reducing costs associated with code maintenance and development. The platform is architected around the MQTT (Message Queuing and Telemetry Transport) protocol version 3.1.1. However, the discovery of “Doze Mode,” a feature of Android API versions 23 and above, has complicated the implementation of wireless communication for consumer facing applications. To get around this, the project must be rearchitected to comply with application service windows.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 Kinderlert(2018-12-06) Biehle, John; Goodman, David W.; Lin, WilliamThis document will explain the aspects of the Kinderlert system.
