The Audio Compressor is a device that will aid the elderly or hearing impaired by helping them listen to the loud and soft passages of their audio. The user can listen to their audio through speakers or headphones. The user will have the option to choose different audio compression profiles by using a knob to cycle through each profile and pressing in the knob to select their profile. Each profile will give the user the ability to customize the dynamic range of their audio. Additionally, there will be another knob allowing the user to adjust the gain of the audio. There will be an LED to indicate to the user if their gain adjustment causes audio clipping. The current status of the system will be displayed to the user through an LCD display on the audio compressor’s enclosure.

The objective of this project is to design and fabricate a device that increases the hardness and surface finish of a wooden, professional league baseball bat by rubbing along the barrel with a harder material. The design employs a pneumatic cylinder to apply pressure to the bat barrel and two stepper motors to rotate the bat and move the pneumatic cylinder along the bat barrel. This system has been designed to operate at adjustable bat diameters and lengths offered by Vander Pro Sports.

Transnational Criminal Organizations (TCOs) are using autonomous surface vessels to transport contraband undetected across the Maritime Boundary Line. Such vessels are difficult to detect, so they pose a threat to national security. Therefore, the United States Coast Guard requires a fully autonomous vessel under a materials budget of $700 that is similar to previously seized vessels and is as advanced as possible in order to determine the best method to detect them before they reach their destination.

Our system is a smart upgrade for conventional doorbell systems that works with the existing residential doorbell components and provides an easy upgrade. It interfaces with an existing 16-24V doorbell and its wiring. When a visitor presses the button, an optocoupler passes a 5V digital signal to an Arduino with Wi-Fi capabilities. When the button is pressed, it sends an event to a host server that uses IFTTT protocol to generate an email and send it to a phone app.

The goal of this project is to create a system which allows a drone upon landing to autonomously dock with, and be secured to a ground based landing pad. The drone will include a control system and sensor suite that is able to detect the landing  location, maneuver itself toward, and align itself with the landing pad. The landing pad will then mechanically secure the drone once the landing procedure is complete. When the drone is ready to leave the landing pad, the process will happen in reverse and allow autonomous flight to once again occur.
