How to Make a Taser (Stun Gun). Posted on October 22, . And so I created the circuit below to create a continuously arcing circuit. The way I. This Stun gun circuit is mostly used as a weapon to stun or send shock waves to the target with the intention to weaken or paralyze it. Here we are building this Stun Gun circuit on PCB. Stun Gun can be dangerous and can cause serious damage if not used properly, we take no.

555 Timer Circuits

You can make other useful devices with this design such as ignitor, a noisy-sparky-dim-inefficient light stun gun circuit, scary Halloween costume, or whatever you can imagine!

So like mentioned in the video you can use a transformer to create very high voltage. But how does a transformer work?

I make it simple here: When you apply Stun gun circuit voltage on one side, you create magnetic field which passes through both windings.

Now changes in magnetic field will move electrons on the secondary and hence create current flow.


You need change in magnetic field to move electrons back and forth, and so transformers only work with alternating stun gun circuit. Now in an ideal transformer the output to input voltage ratio is equal to output winding to stun gun circuit winding number of turns, like I showed in the picture below 60 if for my specific transformer.

Ignition Coil Winding On the other hand, the output to input current ratio it proportional to input winding number of turns to the output, which is backwards the voltage ratio. It reduces the number of connections to the coil, but also eliminates the primary to secondary isolation that is not needed here, but is critical in many other applications such as isolated power converters.

STUN GUN Circuit

So like a regular transformer, if I put 10VAC on the primary of this specific transformer with Unlike a capacitor that tried as hard as it can to keep the voltage across if as stable as possible by sourcing and sinking surges of current, the inductor tries to keep its current stable as much as it can, by surging the voltage across it.

So stun gun circuit you charge it to stun gun circuit certain current, it tries to not allow or slowly change the current.

What does that do for us? Take a look at the circuit below.


At the beginning the current through the inductor L1 is zero. Say it rises to 1A and then we open the switch. But the inductor wants to continue driving 1A current.

So what happens is that it pushed the current through D1, which was off up to this point and turns it on, and the current runs through R1 resistor.

So just that easily, we created 1kV spike. Stun gun circuit means that the voltage across the inductor on the diode side jumped close to V, all in order to continue outputting 1A. This circuit is the basic concept behind the voltage booster circuits.

Just be aware that if you generate huge voltages, stun gun circuit your components such as the inductor, switch, diode and resistor should be able to handle and not break under such voltages.


Now the primary of the transformer is the same as an inductor, it has self inductance. If stun gun circuit charge it and let go like I mentioned, the voltage would spike up and that converts to even higher voltage on the secondary.

My specific car ignition coil has a 0. So if I put 12V across it, I would have 17A through hit. That is beyond my supply and stun gun circuit limit and so pulls their voltages down to a lower level which is still OK.

When I disconnect the supply, I see spark on the primary too because the 10A current tries to keep going and creates a high voltage arc, but also the secondary voltage rises and makes an arc, especially when Stun gun circuit add the capacitor.
