DIY Tazer





Introduction: DIY Tazer

About: i enjoy inventing, taking apart electronics, and rebuilding them. i also have a hobby of creating batch files, i greatly enjoy programming batch. i also enjoy coding and decoding binary code.

In this instructable, i will teach you how to make a very effective tazer out of a bug zapper .


Do not use this on anyone with a weak heart or pacemaker!

Step 1: Step 1: What You Need

You will need:
A bug zapper
A 9 volt battery clip
A soldering iron
9 volt battery
1 Blue led ( or any other color )
1 100 ohm resistor
1 220 ohm resistor
Hot glue gun and glue
Wire cutters/ strippers
Wall adaptor ( see image )

Step 2: Step 2: Start

Start by unscrewing the screws holding the handle together, make sure to keep these.

Step 3: Step 3: Remove the Zapper

Now cut the wires going to the red section, make sure to kep some length.

Step 4: Step 4: Take Apart the Adaptor

Now unscrew any screws from the adaptor, pry it open and remove the metal. Now cut excess metal, keeping the prongs. ( second picture )

Step 5: Step 5: Solder

Now solder the prongs to the wires.

Step 6: Step 6: Cut and Solder.

Now remove the old battery connections. Cut the mounting for batteries, and cut the Springs from the wires. Now solder the 9 volt adaptor. Negative to the board, and positive to the switch.

Step 7: Step 7: LED

Now solder the resistors In Parallel, then solder them to the LED.

Step 8: Step 8: Glue

Now glue the prongs to the opening at the top of the handle.

Step 9: Step 9: Solder

Now solder the resistors to the switch, and the LED to a wire coming fron the circuit board.

Step 10: Step 10: RE-Assemble

Now glue the circuit board into place, fit everything snugly, and screw it back together.

Step 11: Step 11: Your Done!

You now have your very own mini-tazer

Step 12: Video(s)

Here are some videos of the tazer, I'll add one soon of me tazering my friend. ( it'l be great! )

Step 13: Random Fact

Did you know that taser stands for Tom A. Swift's Electric Rifle. Yes i know the title izzz wrong, but it sounds cooler!

Step 14: Final Note

Thank you for viewing my instructable. Please feel free to leave any comments or suggestions, they are appreciated.

    I gave quickly ruined many pocket tazer by using them to make noise to scare the goats out of the feeder, ( they push and shove and knock the scoop out of my hand , knocking feed on the ground which they then won't eat) the tazer makes a great scary sound and they move away so I can fill the feeder. Will this tazer handle being set off in the air just for the sound?

    If i want it to lessen the output voltage, what will I change or remove?

    Can i put a more powerful resistor so that the zapping power reduces and it doesn't hurt much.

    Can you just leave out the LED's? I am not necessarily the sharpest knife in the drawer when it comes to electronics. Plus i'd have to do it all without getting caught.

    Yeah, I just threw them in so it looked cool, and was an obvious sign that it was on.

    I'm not going to download these videos 'cos they look a bit big - what bit rate did you save 'em at and how long are they? L

    well, you don't need to download it, just press open instead of save. I don't know for sure, I think they are 16 bit, I don't know what the standard is, they are each about 1 minute.

    I have to transfer the data from Instructables to my machine, which is a download (to me). At 1 minute each I think the bit-rate is higher than necessary ~1.5 Mbps perhaps, 512Kbps would probably do? L

    just upload them to youtube, then you can a) embed them and b) save instructibles the bandwidth :D

    you already uploaded them to ibles - its 5 minutes work for the greater good of all humanity. :-)

    ill try to do it soon, but i have a control freak mother. i hope that she ;ets me upload them to youtube.
