This Continuity Tester Circuit uses two transistor like small switch for checking wire is good or bad and for that we just need a battery and one LED light. Here, one side touches to battery other side touches the wire and if wire is okay, then current connects through and light will ON, that mean […]

Simple ESR Meter Circuit
To begin with, this article for Simple ESR Meter Circuit show how to make one tool for checking capacitor in phone, laptop and other device. Capacitor work like small battery and it keep some power inside, also we can find bad capacitor without removing it from circuit board and for that we need to use […]
