Introduction: Easy 5$ Pocket Taser
First off here is a video showing me building it in case you get lost, also I show it off a bit
Okay , now time for the safety disclaimer :P
This is a dangerous project, and for that reason, don't shock your friends with it, it could be deadly, so be SMART!
Now with that taken care of, this pocket taser will be a nice bit of protection to take with you anywhere, powered by a simple 9v battery but has a *shocking* output. So with no further a due, I present , the <$5 pocket taser!
Step 1: Watch the Video
or use this -----------> http://youtu.be/wr2XvB95rV8
The video is a great way to see exactly what I am doing, however there are some steps here that I do t have In the video that I found can prolong the life of the taser, so come back after!
Step 2: Bill of Materials
Boost converter - 2.5$
Momentary switch - free salvaged
Dead 9v battery - free
9v battery - I use rechargeable ones , a bit more expensive but pays off fast
Solder, and iron
Electrical tape - 1$
Step 3: Overview of Boost Converter
The shiny red wired are the high voltage. The red wire is the positive and the green is the negative. That's all for that, so let's get started!
Step 4: Step 1
You can buy a 9v battery terminal, but if you want to be thrifty , take apart a dead 9v , and on the back of the normal top, solder wired to the back of it , on the metal pads, ( see video for more help ) remember though, the side that is normally negative on the terminal will be positive when the battery is connected!
Step 5: Step 2
Now get a momentary switch, I salvaged mine from a microwave oven door, and solder wires to the 2 metal tabs
Step 6: ( Optional ) Step 2.5
If you want to prolong the life of your taser, even at the loss of 1/3 the power, then this is for you. Simply follow the circuit above. This circuit means you can use a 9v ( because it is sleaker ) while also powering it at 6v ( the recommended max voltage for the boost converter ) so yeah! Just pretend this circuit is the Batery and connect the + to + of the next circuit and the - to -
Step 7: Step 3
Refer to the circuit above if you need, put the switch in series with one of the terminals for the 9v battery, next connect the positive side with the boost converter and the negative side with the boost converter, solder connections
Step 8: Finishing Touches
Okay now your circuit is compleat !! Go ahead and tuck the wires into the open credits on the converter, and apply so,e hot glue, position the momentary switch and the flat side of the converter.
Now that you have done that, wrap the project in electrical tape, and your good to go!!
Step 9: Notes to Prolong Life Also *Asthetics*
Only use the taser in short bursts, and don't put the two high voltage wires too far apart, if you do, you will probably burn out the boost converter. Also when you are taking it around in your pocket be sure to separate the 9v battery from the taser so that you don't run a risk of accidentally shocking yourself.
Note: As you can see, i redid the project with a smaller momentary switch, and nails as the prongs this makes it much better so you should do it as well! ( i used super glue to glue the switch down ) and hot glue to hold the nail ends in place.
That's all, be safe ( really though ) and have fun! :D
