DIY Torquemeter - How to measure torque! [Arduino & 3D Printed]

Summary

In this video, the creator explores the concept of torque, explaining both static and dynamic torque using real-life applications, such as designing a Tesla turbine and measuring its performance. Through a humorous drinking game involving the word 'torque,' the video offers an engaging, step-by-step tutorial on how to build a DIY torque meter using Arduino, a load cell, and a photo interrupter. The project culminates in the creation of a low-cost, 3D-printed prony brake, allowing the creator to measure torque and rotational speed, ultimately showcasing the power of the turbine. A fun and educational exploration of physics and engineering!

Takeaways

• 😀 Archimedes' lever principle illustrates how the length of the lever affects the ease of lifting a weight, using the concept of torque and energy conservation.
• 😀 Torque is a force applied at a distance from a point of rotation and can be calculated using the formula: Torque = Force × Distance.
• 😀 Static torque does not cause movement, as forces are in equilibrium, whereas dynamic torque results in rotational acceleration.
• 😀 The importance of understanding both static and dynamic torque when designing mechanical systems like turbines or motors.
• 😀 A DIY project involved creating a low-cost torque meter using an Arduino, load cells, and a Prony brake to measure dynamic torque in a rotating system.
• 😀 A Prony brake, invented by Gaspar de Prony, measures torque by applying friction around a rotating axis and links torque with rotational speed (RPM).
• 😀 To measure torque and RPM, the DIY setup included sensors like load cells for force measurement and a photo interrupter to track rotational speed.
• 😀 The project used an Arduino Mega and an LCD shield for data display, with custom code to calibrate and read values from the load cell and photo interrupter.
• 😀 The DIY torque meter successfully measured both torque and rotational speed, validating the setup's effectiveness for measuring small rotational forces.
• 😀 The project included hands-on steps like soldering components, writing Arduino code, and 3D printing parts for the measurement setup.
• 😀 The completed torque meter measured up to 38 watts of power output, demonstrating the potential for use in various applications, such as charging a phone or powering LED lights.
