Schematic Volt

This is a short  High Voltage Generator Circuit Diagram of a high voltage generator and can be mounted in a small space and powered by rechargeable or simple batteries, the circuit generates a voltage low current but a high turn-on of about 200 to 400 V harmless to humans, of course, but is able to give a pretty nasty shock. 

Here is a project that could be useful this summer on the beach, to prevent anyone touching your things left on your beach towel while you was swimming, you can equally well use it in the office or workshop when you return to work. It operates as a low frequency oscillator, which makes it possible to convert the battery voltage into a DC voltage alternating current that can be enhanced through the transformer. 

Using a transformer with center tap as herein makes possible the construction of a Hartley oscillator transistor T1 around The output voltage can be used directly through R2 and R3 current limiting resistors, which should not in any circumstances be omitted or modified, they are what make the circuit have security. You will then get about 200 V peak-to-peak, which is already quite unpleasant to the touch. 

But you can also use a voltage doubler, shown at the bottom right of the figure, which will produce about 300 V, even more unpleasant to the touch. Here too, of course, the resistance, you know how R4 and R5, should always be present. It can be used in small electric fences, chase away animals, etc.
