3V electronic stun gun circuit

This circuit is a cheap version stun gun circuit that is powered by two AA baterry. The output of this electronic project is about 350V dc. The heart of the circuit is the oscillator that is composed of Windings and transistor.

Part List:
  1. Transistor - Tip41 or similar
  2. Resistor - 100-ohms 1W
  3. Capacitor-100nF
  4. C-1.2uF 1000V or any cap with 1000V rating
  5. D-1N4007 diode or similar

Primary and Feedback winding

TIP41 pins

Primary winding P is composed of 16 turns of #24 AWG wire, feedback F is composed of 8 turns of #24 AWG wire, and secondary winding S is composed of 270 turns of #30 AWG magnetic wire. P1 is connected to the collector of transistor, F2 to the 100-ohms resistor at transistor base. F1 and P2 to the battery. The output of Sec winding is rectified by Diode Bridge. The output capacitor is an electrolytic type that is rated 400V above. Capacitance of the output capacitor depends on what available on hand, but always keep in mind that the higher the value the better. this simple electronic project is dangerous when accidentally touched, thus avoid holding the output and discharge the capacitor before and after using.
One of the uses of this circuit is the camera flasher circuit. Source

Today, I went to the beach with my children.
I found a sea shell and gave it to my 4 year old daughter
and said "You can hear the ocean if you put this to your ear." She placed the shell to her ear and screamed.
There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is completely off topic but I had to tell someone!

Very interesting!
Is it possible to raise voltage more than handreds of volts?
Maybe more windigs?


Really great
Stun gun just gives electric shock to the attacker & paralyze the attacker for few minutes. Gives you the time to escape to a safe place.

Nice to be visiting your blog once more, it has been months for me. Well this article that ive been waited for therefore long. i want this article to finish my assignment within the faculty, and it has same topic together with your article. Thanks, nice share. my link

Thank you for all these helpful post. Can truly relate and retain this outstanding post. Very well written. Further info Zoomtargets about gun shops...
