02422 Johnny Builds an ESR Meter. Episode I

The first episode of my ERS meter build. ERS stands for Equivalent Series Resistance and it is a property of all capacitors. It is more critical in high value capacitors used at low frequencies as high ESR leads to capacitor failure. The problem is ESR is usually just an ohm or two so is hard to measure. In this video I review what makes up ESR, demonstrate how to measure it with an Oscilloscope and Function Generator, I then pick and demonstrate a working bread board example of my variation of an ESR meter.

Oh ok what part and what was wrong?? I have been trying to improve it over the past while. Any suggestions will help ;)

Bad audio up to 15:55

Odd sound ok to me though there is some tonal changes. I wonder it it a problem of where it is streaming from. Will have to do a remote download and check the outgoing quality.
