This is the simple electric fish shocker circuit or fish stunner. It helps in catching fish easier, it use 12V battery to convert to 220V AC or 110VAC. We use few parts so easy and cheap.
How it works
This circuit convert voltage from 12V battery to AC 220 volts. Both transistors will alternately work ON and OFF. Because above phase of transformer has same phase with below there.
For example, top transistor conduct current before, the voltage from 12 volts will be sent to the center trap OV to go to the up terminal.
It make the center is positive and up terminal is negative and down of 12V terminal is also negative. Then,the negative voltage at below terminal so make lead B of all above transistors is bias current.
When above transistors stop conduct current. Magnetic field collapses causing a reverse-phase induction center was negative. The positive terminal is 12 volts then,the positive voltage will flow to R to bias lead B of below TR, makes it is the switch to connect circuit causes, induction the 12V to the coil of the lower switch like this forever.
How to builds
Look at the circuit diagram , we use the 12-0-12 volts, 3A transformer = 1 pcs. (the general power transformer) Then, bring the 2N3055 transistor to screw at the large heat sink. Next, connect R-470 ohms, C-0.1uF and Diode-1N4007 as Figure circuit.
You may use the universal board and connect the battery to input andthe output to wires into the prongs to shock the fish.
Current will flow from the second terminal of the wire determines the cause of the shorting it. It does not shock me. Because it does not full circuit. Unless you hold both ends only.
Let the fish cook delicious things from this projects.
