Supercharged 9 Volt battery!!!

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

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!

[che567]

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 ;(

[SilentScreamer]

NOTE: I don't recommend trying anything in this post, if you want to see it try youtube =)

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.

[conrad2468]

why waste your time trying that when you could make one just by using gunpowder?

[MdP1632]

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.

[punkhead58]

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?

Thanks.

[punkhead58]

Yes, I'm quite well aware of this.....this is what we would call sarcasm.

[conrad2468]

 As am i :) this is the part where you play along :(

[conrad2468]

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.

[enginuitor]

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...

A 3300-uF capacitor charged to 9 volts will store, at best: (0.5)(3300 uF)(9 V)^2 = 0.13 Joules of usable energy.
A typical 9-volt battery provides 10 to 20 thousand Joules of electrical energy over the course of its useful life. In other words, the original battery could have held over 100,000 times as much energy as the "supercharged" version.
To give an idea of scale, running a small LED for 10 seconds might use up something on the order of 0.25 Joules, over twice what that capacitor can hold.

For all intents and purposes, this "supercharged" creation is several orders of magnitude less dangerous -- and less useful -- than the original ordinary battery.
Use your heads, people.

AWESOME GEEK TALK! GO NERDS!!!

[luvit]

finally, something worth putting my tongue on. thank u much.

[twisted]

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.

[conrad2468]

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

[Colonel88]

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....)

[Spedy]

*cough*

You can have a 100,000v van de graaf spark and not die from it.
Its the current that kills you. If there isn't enough current flowing voltage won;t do anything.

This definitely won't kill you, but it'd give a nasty jolt....

[abhie007]

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.

[necropolian]

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.

[conrad2468]

interesting!

[necropolian]

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!

[conrad2468]

Ill b a freshman in aug!!! that means i may be able to correct my science teacher!

[LaxLuvr]

im buildin a VDG right now but its only a simple soda can one

[bylerfamily]

Can you tell me how to make it?

[conrad2468]

Make an instructable! I want to build one

[gamer]

It's not even 330 volts, it's charged at 9 volts, so, it has a charge of 9 volts.

[conrad2468]

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

[iloveairsoftstuff]

uh..... don't you have to have a capacitor charger to get an effective charge out of this?

[conrad2468]

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.....

[mo5]

what

[conrad2468]

exactly what i was gonna say

[mo5]

it is better when you read it like 6 times.

[conrad2468]

where did that come from?

[livesteamfan]

I took it from an old power supply I had laying around. I'm using the second one for something else.

[conrad2468]

oh how many volts?

[livesteamfan]

200 volts.

[livesteamfan]

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.

[conrad2468]

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...

[SpringHillWinterPark]

That is the most dangerouse taser ever, Fat Kid!

[conrad2468]

you can just call me XL

[westfw]

Um, what are you charging it FROM? With only a 16V cap it there, it's not going to be THAT exciting...
