How to make simple powerful (high voltage) taser (stun gun) - DIY

Using very cheap and little components (high voltage transformer + 18650 battery holder + 2 plug pin) you can make a very powerful stun gun (taser) for self-defense. All the material combined is less than $10 USD to buy them all. The high voltage transformer claimed to generate around 400,000 volts from 3.7 battery - although this might not be exactly true the transformer is quite powerful indeed. The spark/arc generate very loud clapping sound which can shock someone painfully.

This is a really easy project and using common materials that you can find in the electronic shop except for the high voltage generator which you need to buy from eBay. However please be reminded the device can hurt someone really bad - so don't use it on anyone for playing.

  1. Thank you for this tutorial and for stepping out to do this thing I have all the components on eBay for about £13.36

    1. I think your price you get is quite expensive...the last time i purchase the high voltage transformer cost around £1 in your currency

  2. Actually those chinese boost circuits in those things will likely just piss the attacker off. Wont drop one. They are poorly engineered.

    1. If you combined into two and add more power like 9 volt ...i am sure you will scare the hell out of it....never underestimate China hahaha that is only 4 Volt the snap sound already you can feel the pain.

  3. 12 Mhz crystal oscillator frequency

    Crystal oscillator with many variation of fixed frequency such as

    16 mhz, 4mhz, 12 mhz, 24 mhz, 48 mhz, 56 mhz, 125 mhz, 300 mhz and now with advanced technology they can manufacture up to 1 ghz frequency mostly use in high tech radio frequency equipment.

  4. One of the best 12v car vacuum cleaner you can get cheap at the mr diy store outlet. Coido 12v powered by cigarette lighter slot - is a compact small size vacuum unit that as small as palm size. Yet the motor is powerful and thus the suction power to suck dust and sands from the car cushion seat and floor mat. Although it does not comes with the wet dry multi functionality but it does the job above expectation and i would consider this among the top 10 best cheap vacuum cleaner you can get. Rather than buying phillips, samsung, toshiba, etc brand that cost you hundred of dollars - it worth almost nothing to lose. Other than you probably the coido 12v handheld vacuum could also be found on lazada, shopee, lelong but not harvey norman, senq, amazon, walmart because this is consider cheap stuff.

    Note: Just a note the unit comes only with 1 extension nozzle but that still good enough to do the basic job. The high powered motor is so powerful that if you use it for quite long the cord will heats up. So use wisely and turn it off if not in use.

    Another less best handheld 12v vacuum cleaner is made by the carsun brand also from mr diy store. Despite the machine equally powerful but the suction design is not as good as the coido. It is also very cheap RM35.

    The good about the carsun it comes with wet dry functionality and provided with 2 extra extension nozzle and 1 extension hose. This unit is moderate and the suction is less powerful despite powered by high powered 12 volt car lighter slot.

  5. Another great educational electronic tutorial how to make dark sensor circuit - based on ldr and transistors to automatically switch on and off light during night and day. The circuit is simply plugged and play on breadboard just for demonstration purpose how it is done.
