This is my homemade rat zapper that I made a while back. The device uses the high voltage joule thief circuit(shown in a video that I uploaded to my channel), to charge up 2 high voltage capacitors which I removed from an old CRTV. The power supply is (1) Li-Ion 18650 cylindrical battery which is charged by a simple 300mA circuit. The circuit tapers off charging current as the voltage nears the maximum voltage of 4.18V. Also included is a simple battery voltage indicator. This circuit uses a “lower” voltage(450-500V) at high current, compared to the devices sold in stores which use very high voltage(5,000V+) at a lower current. Both are deadly.
