Build Your Own ESR Meter
Here is a website that can teach you on how to build your own ESR meter. The designer has listed out all of the components and comes with photos too. If you have the time you can follow the schematic given in the website to build one. If you do not wish to build one and ready to get a kitset (that comes with all of the components) to save your time then you can get the Blue ESR meter kitset.
