Balancing Harbor Freight Bench Grinder Wheels: An Electronics Engineer Way

The video explains how to use MEMS accelerometer to quickly balance desktop grinding wheels (stones) in place, when the wheel is mounted on the grinder. The setup uses oscilloscope to find the angular position and amount of counterweight to compensate vibrations. Note that 𝑭=𝑹∗𝑴∗𝝎^𝟐
The phase of the signal (location of the top of waveform) relative to reference pulse period gives the angle where the compensating mass must be placed, and the amplitude is proportional to the required compensating mass. The feedback and likes are appreciated.

You can find many other software oscilloscope software for PC and Android online. Note that the soundcard should have high input impedance ( greater than 100kOhm). Usually, line input of typical sound card is suitable.
