Here is a simple low power inverter that converts 12V DC into 230-250V AC (DC to AC Converter). It can be used to power very light loads like window chargers and night lamps or simply give a shock to keep the intruders away. The circuit is built around just two ICs, namely, IC CD4047 and IC ULN2004.
