• Part D: Capacitance measurement

  Husain Shekhani • 04/05/2017 at 17:07 • 0 comments

  In this project log, we are going to measure the capacitance of the ultrasonic transducer using both AC excitation and also DC methods (time constant).

  More fun with USB oscilloscopes!

  
  

• Part C: Resonance Frequency by Mechanical Impluse

  Husain Shekhani • 04/03/2017 at 22:15 • 0 comments

  In this project log, we will show how to determine the resonance frequency of the transducer using a mechanical impulse, namely, hitting it with a marker.

• Part B: Resonance Frequency by Excitation

  Husain Shekhani • 04/03/2017 at 22:13 • 0 comments

  In this project update, we use a USB oscilloscope, a resistor, and voltage probe to determine the resonance frequency of the ultrasonic cleaning transducer using excitation. The resonance frequency occurs at the largest current frequency.

• Part A: Introduction to DIY Ultrasonic Cleaner

  Husain Shekhani • 03/28/2017 at 21:56 • 0 comments

  In this video, I describe the project in general.

  We are going to need:

  1. Signal source

  2. Amplification

  3. Drive transducer

  4. Bond transducer to container

  Yes, there will be a lot of details to come. Best of all (maybe), we will use an Arduino to drive the cleaner, hopefully.
