Introduction

After closely evaluating my potential three design ideas for the two-week project, I have decided to make a thermoacoustic engine. Its visual appearance and cool mechanics make it eye-catching and interesting to make. In this blog post, I will take about my plan and the materials required to create a thermoacoustic engine. The attached video below is the kind of thermoacoustic engine that I intend to make.

Plan

I have created a schedule from Feb.13th to Mar.5th for my two-week project, divided into four sections: Define and Inquire (D&I), Develop and Plan (D&P), Create and Improve (C&I), and Reflect and Share (R&S). Detailed information is included in the schedule. The schedule included deciding on the project, designing the project, ordering the materials, testing the materials, asking and receiving feedback, and reflecting on the feedback.

Design

Above is the design of my thermoacoustic engine. It is composed of three main sections: rod, piston, and wheel. I included a screenshot and a zoom-in for each section so that the design is clear and easy to follow.

Materials

According to the design, here are the materials required:

• One 25*200mm Test Tube
• One Wooden Cylinder with a diameter of 10mm and height of 30mm
• One 10*100mm Wooden Stick (connected to the wooden wheel)
• Two 10*10mm Wooden Pieces (glued onto the carbon rod)
• One 150*150mm Wooden Wheel 
• Two 30*50mm Wooden Pieces (hold the test tube and the wooden wheel)
• One 60*400mm Wooden Piece (the base of the engine)
• One Toothpick/Wooden Piece (connect the stick and the rod)
• One 2*3.15*10=63mm Heat Resistance Tape
• One 0.5*0*5*20 Carbon Rod
• One Steel Wire Ball
• One 50mm Screw 
• One Nut

Apparatus

• Hot Glue Gun
• Wood Driller
• One Candle
