Scare the crap out of your friends with this new "supercharged" 9 volt battery!! WARNING: If you have a pace maker or are dependent on any other electronic device for life support do not touch this battery!!!! also i am not responsible for ANYTHING stupid you do with this including but not limited to loss of life or loss of property due to 1 hell of a jolt!
ALSO make sure the capacitor is discharged before you go messing with it

Step 1: Parts!!!!

2 9volt batteries!
1 soldering iron w/ soldier
1 hot glue gun w/ hot glue
1 16v 3300uF capacitor
common sense

Step 2: Taking Apart the Battery.

All you have to do is bend the metal flaps on top of the battery and lift out the top part you can throw the insides and the little cardboard thingy @ the top!!!! not the bottom!

Step 3: Soldier and Make Sure the Wires Dont Touch the Sides

NOTE AND A WARNING MAKE SURE THAT WHEN YOU SOLDIER YOU SOLDIER THE + TO THE + AND THE - TO THE - or you capacitor will EXPLODE!! ok now soldier the terminals to the + and - terminals of the battery on the other side ie where you cant see them (Note:bend the wires a little because the capacitor wont fit into the battery do as I do) now be sure the wires dont touch the sides then apply hot glue to the wires! put the capacitor into the case (after you coated the wires with hot glue) then add as much hot glue as possible then cover it up and seal it with hot glue to make sure it doesnt open! Your capacitor should look like this

Step 4: FINISHED!!!!!!!

Move on to step 5 for charging! NOTE at a GLANCE this looks like a 9 volt but with closer inspection it is actually a tazer A.K.A. a "supercharged" 9 volt battery!

Step 5: CHARGING

when you charge it is also imperative that you touch the + to the + and the - to the - to avoid an explosion in your hand even though it may look like the perfect fit it should never be attempted i did this as a safety thing so you dont over charge the capacitor and cant get the battery off so you have to hold it there while it charges


to charge just apply the + to the + and the - to the - for a few seconds and let off then test it out on your cat or dog or wife or friend or husband (anyone who wont bit and or kill you if you try this on them)


Hope you enjoy this!!
<p>I made this with a 25v 1000uf cap.</p>
<p>no schematic diagram?</p>
Will this actually shock you on your bare skin?
So what ya charging it with? If you were concerned about it locking on, it would seam you are charging with another 9v battery? In that case, you can leave a 9v battery connected to a 33v cap indefinitely with no ill effect. Getting locked with the polarity reversed is likely to ruin the cap though; as they don't like reverse charges.
uhm.. i made this and i think i put the -to the+ and i used it before reading this and it worked just fine for me... but maybe it explodes on the 5th or6th time or something so someone help!!! i dont want to use it if its gonna explode and i dont want to waste it if it doesnt matter! aaaaahhhhhhhhhhhhh!
exploding is the least of worries, i rigged it to blow and i got a pathetic little steam, i thought it was gunna go off like a grenade, they are designed for safety, if your capacitor has a cross carved into the end of it in the metal, instead of it exploding it will force steam out of this structurally flawed weakspot, its damn hard to find unsafe capacitors, i want a hand grenade ;(
NOTE: I don't recommend trying anything in this post, if you want to see it try youtube =)<br><br>Capacitors only explode impressively with voltages well above their rated maximum from my experience though I've never seen anything other than smoke, a big bang and a case flying around. Automotive bulbs though are very impressive with 230V AC though they cause glass to be propelled in all directions.
why waste your time trying that when you could make one just by using gunpowder?
It won't explode. At least not because of that. Just remember the polarity is opposite to what it should be and you should be fine.<br />
Would you be so kind as to upload more pictures of the case bursting open and battery acid spewing forth into your eyes and face? <br /> <br /> Thanks.<br />
Its all healed up about now ;) if your talking about the 9 volt battery that i dismantled, there is no acid in there whatsoever. If the capacitor were to explode.....well im not sure what would happen.<br />
I'm sure this has been pointed out somewhere along the line, but the voice of reason seems to get drowned out all too often around here...<br /> <br /> A 3300-uF capacitor charged to 9 volts will store, <em>at best</em>: (0.5)(3300 uF)(9 V)^2 = <strong>0.13</strong> <strong>Joules</strong> of usable energy.<br /> A typical 9-volt battery provides <strong>10 to 20 </strong><strong>thousand Joules</strong> of electrical energy over the course of its useful life. In other words, the original battery could have held <strong>over 100,000 times as much energy</strong> as the &quot;supercharged&quot; version.<br /> To give an idea of scale, <strong>running a small LED for 10 seconds </strong>might use up something on the order of 0.25 Joules, <strong>over twice what that capacitor can hold</strong>.<br /> <br /> For all intents and purposes, this &quot;supercharged&quot; creation is several orders of magnitude less dangerous -- and less useful -- than the original ordinary battery.<br /> Use your heads, people.<br />
AWESOME&nbsp;GEEK&nbsp;TALK! GO&nbsp;NERDS!!!
it wont kill you. gosh. Unless, that is, you have a weak heart. Its 330 volt. at pracally no amps. In a way you can say volts do not kills, amps do. while, even at almost no amps... 11,000 volt WILL killl you.... 330 will not. please dont get me wrong... it hurts like crap still. hahah *note on the intstructable* You could just reverse the polarity of the capacitor in the battery casing to avaoid the whole "+to+ and -to-" thing. Cool idea.
*cough* <br/><br/>You can have a 100,000v van de graaf spark and not die from it. <br/>Its the current that kills you. If there isn't enough current flowing voltage won;t do anything. <br/><br/>This definitely won't kill you, but it'd give a nasty jolt....<br/>
It is true that its the current that kills you, but what most people don't know is that high current will certainly kill you but low current is also equally dangerous. Currents in range of 0.1 to 0.2 amp are supposed to be the most dangerous as they cause fibrillation, in common terms it causes the heart to beat irregularly and eventually causes a heart attack, and the heart stops beating even after the current is removed. This current range is known to interfere with the electrical pulses that control the heart muscles. Current ranges between 0.03 to 0.07 amps can cause breathing problems. So it is highly recommended that you test the current and not just the voltage output of these homemade toys before trying them out.
and to think, that the whole 'contraction' comes from a very, very small area on the right...um...well....uhh... in latin, it's called atrium. it get's disturbed pretty easy.
interesting!
i know. i know twenty times more about the heart and kidneys than we should know for our exams. it's just so much fun to (constantly) correct the biology teacher (who knows only what's in our books, nothing more), because the schoolbooks aren't right all the time. and, it's very interesting, indeed!
Ill b a freshman in aug!!! that means i may be able to correct my science teacher!
im buildin a VDG right now but its only a simple soda can one
Can you tell me how to make it?
Make an instructable! I want to build one
thanks for the note I realized that when I made it but I didn't want to get confused and have a bomb in my hand so to prevent confusion I delivbrately made + to + and - to - but thanks for the comment
One time iw was getting at the flash circuit in a camera with a metal knife. So you know what will happen...Never dissasemble a charged capacitor with a metal object with a handle that is metal(i got so scared....)
It's not even 330 volts, it's charged at 9 volts, so, it has a charge of 9 volts.
yeah i always have this notion that you can OVERCHARGE capacitors and i was parinoid so i just made it like that for quick disconnection of battery
finally, something worth putting my tongue on. thank u much.
uh..... don't you have to have a capacitor charger to get an effective charge out of this?
Actually you do....i just figured out that a 9volt battery does not provide a sufficient charge to do any damage.....you should look up the guys who said his was similar to mine....he added a charger.....
what
exactly what i was gonna say
it is better when you read it like 6 times.
where did that come from?
I took it from an old power supply I had laying around. I'm using the second one for something else.
oh how many volts?
200 volts.
How much of a jolt could I get from a 560uF, 200V cap? I know that I should not charge it to the full 200 volts if I should use it on someone.
the caps only charge what you put in them...im not an expert or anything but dont go pluging your cap into an outlet but a 12 volt car/boat battery would do a good job of making enemies...
That is the most dangerouse taser ever, Fat Kid!
you can just call me XL
Um, what are you charging it FROM? With only a 16V cap it there, it's not going to be THAT exciting...
i just hold another 9 volt battery there for a few mins and test it out on a quarter or something metal also its not supposed to be i dont want the guy im tazing to knock me out i want him to laugh i am also working on a dual capacitor model
hope you know that a capacitor will always keep a charge equal to it's charging source....this means : source = 1.5 volts ...so....capacitor charge = 1.5 (slowly &quot;vanishing&quot; ) volts...<br/>so...your 16 volt capacitor isn't needed if you're charging it using another 9 volt battery....just cause it will never reach it's max operation voltage...<br/>
the cap will charge almost instantly. Infact it's more likely to explode if you hold it on for too long than if you touch it barely w/ the terminals backwards
you take the 2nd battery and put it together
We used foil caps, capacity in the 200nF range, but at 1500V. There are low leakage models from Rifa. They can keep the voltage for days. Hehe...
I agree that this is not supercharged, but atleast Conrad has worked out that using a large capacitor results in a fair shock. Admitadly 9V isn't too impressive, but at 3300uF he's gonna be storing 0.13J of energy. A fair amount to have dumped as quick as a capacitor can. Of course we all know that capacitor discharge time depends on resistance * capacitance. On the tounge (wet with little resistivity) you may well see that 0.13J in an instant and get a whack, but on dry skin it is just going to leak out slowly, a tingle at best.<br/>Of course it sparks to metal, with very little resistance the charge leaves very quickly and could spark, all be it at a minute distance thanks to the low voltage.<br/>Due to the fact that both electrodes are so close together I'd be very suprised if anyone was ever injured by this as you really need to cause a electrical path across the heart to do damage - impossible with electrodes next to each other.<br/>Someone else commented about overcharging a capacitor being dangerous, it isn't. As long as the voltage is lower than that rated on the cap then all will be fine. If its electrolytic then it has to have the correct polarity too, +to+ etc.<br/>Reverseing an electrolytic can indeed cause explosion, but if you get it the right way round a capacitor will charge and then current flow will cease.<br/>I think most of you guys have got this, it is most definately current that kills and not voltage. High voltage is associated with high risk as it can penetrate the skin. 1V can kill you if it gets through your skin.<br/>
well its the biggest capacitor i can put into it i might be able to fit 2 ill put another instructable or edit this one to add another cap to it
I doubt you would even feel a tingle if you put two fingers across your <em>&quot;Supercharged 9 Volt battery!!!&quot;</em><br/><br/>LAME!<br/>
