About this document
DIY Non-Contact Voltage Detector Guide by Satheesan P is a document available to read on EtoBox.
This document provides instructions for making a DIY non-contact voltage detector using only 4 components: two transistors, one resistor, and one LED. The circuit diagram shows how to connect the components in a simple circuit. The circuit is then enclosed in two bottle caps, with holes for the LED and battery connector wires. Once assembled with a 9V battery, the detector can be used to check for voltage in wires without direct contact by seeing if the LED lights up as it
