Homemade ESR Meter

esr meter

I could say that ESR meter is one of the best testing equipment in helping me to locate bad electrolytics in electronic boards. If you scan through the internet you would know that ESR meter comes in many different kind of prices. Some were cheap like the dick smith esr meter (kitset) while some were expensive like the B&K esr meter and the sencore lcd103c capacitor and inductor analyzer.  If you do not have one and wish to build one at the comfort of your home or working place, visit this website for the esr meter project idea.
