Soldering Assignment

Description

The soldering assignment is a basic soldering exercise that ensures all ECE 445/ME 470 students understand how to solder surface-mount and through-hole devices. Students will be provided with the necessary PCB, components, solder, flux, etc. The details of the soldering assignment can be found in the assignment sheet.

Your end product should look similar to the following. You will create a small device that blinks an LED at varying frequencies when the button is pressed, based on a potentiometer reading.

Below is a series of soldering tutorials. The critical ingredient that you need to make your life easier while surface mount soldering (and through-hole too) is flux. There is liquid, water-soluble flux available in the lab. If you can't find it or don't know what it looks like, ask a lab staff member or TA for help.

Requirements and Grading

The soldering assignment is worth 10 points and is graded via inspection by a TA or Lab Staff member. Students are allowed to make as many attempts as necessary to complete the assignment.

Submission and Deadlines

The soldered PCB must be presented to a course staff member before the deadline listed on the Course Calendar.

Video Tutorials

# TITLE OF THE PROJECT

Augmenting AR/VR with Smell

# PROBLEM

Augmented Reality (AR) and Virtual Reality (VR) technologies are rapidly growing and becoming more prevalent in our daily lives. However, these technologies have not yet fully addressed the sense of smell, which is a critical aspect of human experience. The absence of scent in AR/VR experiences limits the immersive potential of these technologies, preventing users from experiencing a full sensory experience.

# SOLUTION OVERVIEW

The solution is to augment AR/VR experiences with smell, enabling users to experience a full sensory experience. This will be achieved by incorporating hardware and software components that can simulate various scents in real-time, in response to events in the AR/VR environment. The solution will consist of a scent-emitting device and software that can track and simulate scents based on the user's location and orientation in the AR/VR environment.

# SOLUTION COMPONENTS

The solution will consist of the following components:

- **Scent-emitting device**: This device will be designed to emit various scents in real-time. It will be portable and lightweight, making it easy for users to carry around during AR/VR experiences.

- **Scent simulation software**: This software will be designed to track the user's location and orientation in the AR/VR environment and simulate scents accordingly. The software will use various algorithms to determine the intensity and duration of scent emissions.

- **AR/VR hardware**: The solution will require AR/VR hardware to create the immersive environment. This hardware will include AR/VR headsets, controllers, and other peripherals necessary to interact with the AR/VR environment.

# CRITERION OF SUCCESS

The success of the project will be determined by the following criteria:

- **Immersive Experience**: The solution must provide an immersive AR/VR experience that incorporates smell as a key sensory input.

- **User Acceptance**: The solution must be accepted by users, who should be able to appreciate and enjoy the experience.

- **Technical Feasibility**: The solution must be technically feasible and reliable, with a low latency and high accuracy in scent simulation.

- **Scalability**: The solution should be scalable and adaptable to different AR/VR environments and hardware configurations.

- **Safety**: The solution must be safe for users and the environment, with proper ventilation and control mechanisms to prevent any harm or discomfort caused by excessive or inappropriate scent emissions.
