Q & A
What is the main focus of the lesson?
-The main focus of the lesson is the assembly of an ultrasonic transducer, including the preparation and setup required for its proper functioning.
What are the essential components needed to assemble an ultrasonic transducer?
-The essential components needed include the transducer itself, a metal container (like a pot or metal cup), and a support mechanism for the setup.
How does the ultrasonic cleaner look like?
-The ultrasonic cleaner consists of a metal container (like a bowl or pot), the ultrasonic transducer placed inside or at the bottom of the container, and possibly a mesh insert for holding a beaker or solution to be cleaned.
What is the significance of the electrode and the wires connected to the transducer?
-The electrodes and wires are crucial for the electrical connection and functioning of the transducer. The red wire is connected to the middle electrode, and the black wire is connected to the other electrode, which is grounded for electrical safety.
Why is it important to use weights when attaching the transducer with epoxy?
-Weights are important to hold the transducer in place while the epoxy cures, ensuring that the transducer does not shift and maintains its correct position for proper adhesion and function.
What type of container was used as an example for the assembly?
-A cleaned paint can was used as an example for the assembly, which was sanded and cleaned to provide a suitable surface for epoxy adhesion.
How was the transducer attached to the paint can?
-The transducer was attached to the paint can using Gorilla Glue epoxy, with weights applied to ensure it stayed in place while the epoxy cured for 24 hours.
What was the purpose of the zip tie in the assembly process?
-The zip tie was used to secure the transducer-mounted paint can inside a larger plastic container, ensuring that the transducer remained in the desired position and was properly supported.
How will the transducer be tested in the next lecture?
-In the next lecture, the transducer will be tested by characterizing its impedance versus frequency in three different states: free by itself, unloaded (with the paint can attached), and loaded (with water added to the container).
What ultrasonic energy range will the red lead be subjected to?
-The red lead will be subjected to ultrasonic energy in the 40 kilohertz range for testing purposes.

🔧 Assembly and Characterization of Ultrasonic Transducer
This paragraph discusses the process of assembling an ultrasonic transducer. It begins with a recap of the previous lecture, where the focus was on programming the impedance response of the transducer. The speaker then moves on to describe the necessary components for the assembly, which include the transducer itself and a metal container, like a pot. The importance of supporting the setup to prevent the transducer from laying on the floor is emphasized. A detailed description of the ultrasonic cleaner setup is provided, including the placement of the transducer, the use of a mesh container, and the process of cleaning objects like screws within it. The speaker also explains the electrical connections, highlighting the importance of attaching the ground wire for safety. The paragraph concludes with a focus on using epoxy to secure the transducer and the use of weights to ensure proper adhesion.
🛠️ Customization of Ultrasonic Cleaner with Paint Can
The second paragraph delves into the customization of an ultrasonic cleaner using a repurposed paint can. The speaker describes the process of preparing the paint can by sanding the top and cleaning it to ensure proper adhesion of the epoxy. The use of Gorilla Glue epoxy is mentioned, along with the careful application and the importance of allowing it to cure for 24 hours. The assembly involves attaching the transducer to the paint can, securing it with weights, and creating a supporting container from a yogurt box. The speaker provides a step-by-step guide on modifying the container, drilling holes for wires, and using a zip tie to secure the paint can inside. The paragraph concludes with a brief overview of the completed setup, emphasizing the successful assembly of the ultrasonic transducer and its housing.
🧪 Characterization of the Ultrasonic Transducer Post-Assembly
The final paragraph focuses on the characterization of the ultrasonic transducer after assembly. The speaker outlines the three ways in which the transducer will be characterized: free by itself, unloaded (attached to the paint can), and loaded (with water added). The goal is to analyze the impedance versus frequency of the transducer in each state. The paragraph concludes with a teaser for the next lecture, where the speaker plans to describe low power testing and further analysis of the transducer's performance.
