Analog Capacitor ESR Tester
TallMan's lab @ runawaybrainz.blogspot.com build a nice looking and simple analog ESR capacitor meter based on a EEVBlog forum topic. I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version by EEVBlog member Jay_Diddy_B....

Circuit lets you test capacitors for leakage
Raju R Baddi @ edn.com has published a circuit that enable you to test electrolytic capacitors and decide if worth using it on a circuit. The values in the figure are typical for general testing of all capacitors, from 1-nF ceramic versions to 1000-μF electrolytic types. The value...

OpenCVMeter – Rediscover Your Capacitors
OpenCVMeter is an open source tool to measure capacitance and leakage current as a function of a capacitor's working voltage. When designing circuits, many hobbyists take capacitors for granted - but each type (ceramic multi-layer, aluminum electrolytic, tantalum, mica...) has its...
