I have had a lot of fun with this project so I decided to share it with some of you pranksters out there. Basically, we will be modifying a can of Altoids Mints to shock someone when they try to pick it up and steal your candy.The two basic components are a can of mints and the circuit board from a used disposabale camera.

Step 1: Materials

This project can be done for less than $3.50.Most of the materials can be obtained very easily and are relatively inexpensive.You can get a used disposable camera for free at Walgreens or almost any place that develops film.Just ask them and see what happens (I got 12 cameras on my first try!) You will also need a AA battery holder available at any Radio Shack for about $1.00 (holder not shown in photo).Everything else is listed below:

1.Altoids Mints can
2.Disposable Camera
3.26 AWG wire
4.Wire cutters
5.Solder (or Wire Glue)
6.Electrical tape/Scotch tape
7.AA battery holder

Step 2: Disassembling the Camera

First you must take apart the disposable camera to access the circuit board inside. This can be done by simply prying open the camera case with a small screwdriver.Use the screwdriver to lift up on the plastic tabs located along the seam of the camera (you may have to remove part of the paper label to do this). DO NOT TOUCH ANY PART OF THE CIRCUIT BOARD WHILE DOING THIS OR YOU MAY GET A NASTY SHOCK.

Once the case is opened and the halves are seperated, locate the battery and remove it immediately.Please remember not to touch the circuit board because it may still have a residual charge even after the battery is removed.

Step 3: Removing the Circuit Board

Before removing the circuit board,it is important to discharge the capacitor to avoid being shocked.

The capacitor is the large,black cylinder with two metal posts attached to it.To discharge it,simply touch the two metal posts at the same time with a screwdriver (you may hear a loud noise and see a bright flash of sparks). It will scare you to death but get over it.

It nothing happens then the capacitor was'nt charged to begin with and in either case the circuit board can now be safely removed by gently pulling it out with your fingers.

Step 4: Modifying the Circuit Board

Moding the circuit board is rather simple.First, remove the capacitor by cutting through the two metal terminals with a pair of wire cutters.Throw the capacitor away.Now solder two pieces of 26 AWG wire to the two contacts where the capacitor used to be.

Next,locate the little metal button near the center of the circuit board.This is usually only held in place with a piece of tape and can easily be removed. Once the button is removed,replace it with a dab of solder.Be certain the solder touches both of the circuit pathways so they are connected permanently (in the photo I have used a dab of conductive Wire Glue in place of solder).

Also,break off that long metal arm on the circuit board as it will only get in the way later on.

Step 5: Attaching the Battery Holder

The battery holder is easily attached to the circuit board.Simply strip the ends of the positive and negative wires and then twist them onto the two metal tabs that used to hold the battery (be careful not to reversed the positve and negative).

You could also solder the wires on to the battery terminals but I hate to solder and always try to get around it whenever I can.

Also,I like to put a piece or two of electrical tape over the metal terminals just to make sure they don't touch the lid of the box (this will become more apparent later on).

Step 6: Modifying the Mint Can

First,remove the lid from a can of Altoids by gently prying up on the two metal tabs that hold the lid in place.It is very important that these metal tabs are bent back far enough so they never touch the lid of the box as this will be important later on.

After removing the lid,coat the inside of the box with several layers of electrical tape.Add a few more layers to the walls of the box so that the circuit board and battery case will fit nice and snug.Leave a small area exposed so that one of the wires can be attached directly to the metal can.

Also,coat the rim of the can with some clear plastic tape.Make about a 1/4 inch flange all around the rim of the can so that the lid and can are never in contact with each other.

Step 7: Inserting the Circuit Board

Insert the circit board and battery holder into the can as shown in the photo.Tape one of the wires coming from the capacitor leads directly to the metal inside the can (remember you were supposed to leave a bare spot with no tape). This wire will 'electrify' the can (be sure the end of the wire is stripped so it comes in good contact with the can)

The other capacitor wire is bent over the rim of the can about 1/4 of an inch.The clear tape on the rim of the can will insure that this wire does not actually come in contact with the can itself.The purpose of this wire is to come in contact with the lid when it is placed on the can (thus 'electrifying' the lid). Please take note that the circuit board is always 'live' when the battery is in place (you get about 4 hours of shocking fun out of a standard AA battery).

You are almost finished but be sure to sand off some of the paint on the metal tabs.When the lid is in place,touching the lid and one of the metal tabs at the same time creates the electric shock.Also,the paint on the can acts as an insulator but tiny scratches in the paint can allow electricity to 'leak' through and shock you.That is why I like to coat the can with a couple layers of clear lacquer (though rubber cement may work just as well).I WOULD BE HAPPY TO MAKE ONE OF THESE FOR YOU IF YOU CAN'T DO IT OR DON'T HAVE THE TIME.FEEL FREE TO CONTACT ME IF YOU HAVE ANY QUESTIONS OR CONCERNS.ENJOY!!
Thanks man. So cool my sons and there buddies love it... Nice. The wife doesnt though, ha but we do when she grabs it. need more prodjects like this. right on my dad had a simular box like this when i was a kid, i mailed him one he called me laughing forever, ive never heard him like that, priceless, again Thank You. D
So all you do is remove the capacitor and shock someone with the capacitor charging circuit?
I tried making this but I think the paint isn't electrocuted because it won't shock. What am I doing wrong?<br>
try using clear fingernail polish instead of clear tape, its alot less noticable.
Yes,but the clear nail polish will eventually chip off and then you are screwed.If the lid and can touch then you will not get shocked and may even short out the circuit board.
good point
As long as the current is not higher than 2-3 milliamps there's no danger. Spencers has perfectly legal perfectly safe shocking devices.<br /> <br /> Why did you take out the capacitor? It will prolong your battery life and give you a steady discharge rate no higher than the capacitors rating which is 330VDC.<br /> <br /> I have made one before with a metal candle tin that was big enough that i could pad it with foam to protect the circuitry from damage. I also used a 600vdc capacitor with a variable resistor so i can select the out put voltage and a selector switch so i can turn it off and on without removing the battery.<br /> <br /> Just my two cents worth.
Hey.If you have ever been shocked by a capacitor then you would understand.BANG!!! Good way to burn someone's skin and make there arm go numb for 10 minutes.I just want to surprise them...not hurt them.
<p>I have been shocked by a capacitor. No big deal. The shock boxes i have made ALL have capacitors in them and no one has ever got burned or had their arm go numb. I'm a certified elctrician and i can tell you if done correctly using a capacitor is perfectly safe. It's not going to be a &quot;BANG&quot; situation just a funny one. Go get the shocking game from Spencers and open it up and you'll see a capacitor.</p>
You know how dangerous this is right?
Actually,a taser is much more dangerous and is completely legal.Very low amperage and only 320 volts=very safe.The capacitor is removed in my tutorial just for extra safety.You are a snowboarder and are worried about danger?(LOL)<br/>
<p>a taser is a self defense device. if you were to &quot;tase&quot; someone when they were stealing your altoids, that is illegal.</p>
Yes but this is only 300 volts and is not enough to 'tase' anyone.Tasers put out about 30.000 to 50,000 volts--Jimmy
No there is a difference between snowboarding and stupidity. <br /> <br /> SNOWBOARDING: I wear a helmet to protect my head= SMART<br /> DIY TASER &quot;PRANK&quot;: Using electricity to purposefully inflict pain= STUPIDITY<br /> <br /> Yes while i do agree its a low amperage, there is still always a possibility for error when dealing electricity. On the other hand I'm not sure tasering people is &quot;completely legal&quot; in every state/country so go ahead and taser a teacher at school or a boss at work and see what happens :D<br />
actualy, with the cap gone, theres 3X as much voltage
I wanna see something that activates the camera flash when you open the lid so the person looks in a gets flashed. This looks good too and i will try it.
Hey that's a fun idea. However,these used camera flash units sometimes fail to work.The shock part works but you will have to locate the mechanism that causes the flash.Have fun.
some producers such as kodak have smaller circutboards about half thesize. When you discharge them you have to make sure not to touch thesetwo really thin metal posts. You can for fun but you will fell a smallshock and dont make those 2 posts touch eachother. They are a switch andwill set of the flash, ouwch it is blinding<br />
More pics please.
Hey there.If you could please be more specific then I can help you.What part is giving you trouble?
Basically the part about where how to tape it, and I was confused by the clear tape.
Hey again.You just take a piece of clear plastic tape and fold it around the rim of the can on all sides.This prevents the lid from coming in contact with the can.When the lid is in place it must not contact the can at all.Even the slightest cut or breech in the tape will result in a non working project. The other purpose of the clear tape is to prevent the second wire from coming in contact with the can.That is the wire that is folded 1/4 of an inch over the rim of the can.When the lid is on the can it will contact that wire.Of course,you could simply tape that wire directly to the inside of the lid while the other wire is taped to the inside of the can.The idea is to keep the lid and can seperate or you won't get shocked and could even short out the circuit board.
Thanks, I was a little confused about how it worked, but I see now.
