Cheap/free capacitor bank and charger

Step 6 We're finished! Now what...

Now that you have a nice little capacitor bank, what are you to do with it?

I plan to build assorted small scale electromagnetic goodies, but it's up to you really. Here are some links you might find interesting, I know I did.

Micro railgun
Mini coil launcher
Lots of coilgun info

Well, that's all for now, once I build coil/rail guns I will post instructables for them :D

Thanks for reading, leave a comment :)

It seems this relatively simple design would work for an emp generator experiment?

[Derin]

what is a emp generator?i know i am dumb

[TheDeviant13]

emp stands for "Electromagnetic-Pulse" EMP pulses can knock out electronics such as radios and will make crt TV's

[freerunnin1]

doesn't an EMP destroy capacitors or something? therefore rendering electronic equipment useless or is it just temporary?

[S33PlusPlus]

I realize this is rather old, but EMP affects anything sensitive to sudden current spikes (i.e. semiconductors). Theoretically you *could* trash a capacitor with an induced current, but in reality all the transistors would explode far before a capacitor would catastrophically fail.

And @TheDeviant13: What do you mean "will make CRT TVs"? It will screw up the picture pretty bad, but that goes for all magnetic fields.

A little explanation to greasefire's response: Note that I am no expert on the subject; but I think I have a fairly accurate grasp on it. An electromagnetic pulse is a powerful magnetic field that, due to electromagnetic induction, creates a voltage differential between metal objects. For example, a large EMP near an RFID tag would create a voltage differential between different parts of the antenna, which could potentially fry the chip and or antenna.

This would absolutely work, in fact, i made one work using the individual charger output

[Greasefire]

EMP is shorthand for "electromagnetic pulse". In Ocean's eleven, they used a generator the size of a van to knock out the casino's power grid (along with half the city's! ;])

[googleman]

oceans is cool

[firemanfu]

you also get an emp from a nuke going off

[alphapyr0]

not just any nuke it would have to be a ytterbium core HE rail nuke.

[arizonadixon]

this is not necessarily true, any nuclear weapon with sufishint gamma output that is detonated above ~15km will produce an EMP of significant power.

[tulavatalo]

the nuke creates a emp that krashes most elektronik devices in a raduis of 10km

[dumle29]

a nuke would fry way more than stuff in 10 km radius

[tulavatalo]

it depends on the altitude of the detonation a nuke is often detonated about 500 m above ground but if you blow a nuke at 10km altitude it would take out eny not shilded electronics in an area the sise of usa

[OXI2vasyl]

are u watched future weapons on discovery channel xD

[tulavatalo]

jepp

[dumle29]

exactly

[scottjones1998]

right before it blew you to pieces

[Biscuitus]

Actually no.

An EMP is generated from a nuclear device being detonated at altitude. It's also known as an "airburst" In the Cold War days it was thought that Soviet forces would lead a nuclear attack with a series of airbursts to knock out civilian infrastructure. The actual effects of the blast is not very great because they don't have to use a "city buster" (a device in the megaton range) to get the same effect, so the heat, blast and all of that wouldn't be as great because it's fairly high up (think miles).

How do I know this? I was in the military and it was my job to know.

[GIBBERATOR]

how powerful is this, or will it just make a weak coil gun?

[mattplatt501]

too bad the nuke will destroy EVERYTHING that gets fried by the EMP it gives off.
