Iron Man Inspired Repulsor Beam Blaster V1.0

Homebrew repulsor beam blaster that’s designed to produce extremely intense burst of light that can be used to repulse your archnemesis, girlfriend, wife and pet cat :P

Coincidentally a few days ago (July 13th) is the “Embrace Your Geekness Day” and what better way to embrace you inner geekness than making your own super hero inspired gadgetry.

Have fun!

Step 1: The Circuit

The repulsor is essentially two circuits that are switched ON/OFF using a DPST switch.

The source of the DC Step-up Charging Module is the good old analog cameras. When extracting the module, mark the wires so you don’t mix them up. If you have one lying around, then don’t waste time reinventing the wheel. If not, then google is your friend.

Do not short the lead of a charged capacitor, it will pop in your face, literally. I learnt my lesson the hard way a while back. Play safe, always have a large resistor handy, discharge the capacitor via the resistor before you begin to fiddle with it.

The purpose of the discharge switch in the schematic is to short and safely discharge the capacitor when it’s no longer in use.

How long does it take to make?

Working on one right now, and I've just finished the electronics. A combination of this instructable and these two other repulsor gauntlets would be awesome!

Is this very disorienting if you get it full in the face?

[T-K]

Try it!

[Icalasari]

I want to know this. It could be VERY useful then...

[Sarrx]

Could a similar version of this be made with high power leds so that it would literally have a beam of light as well as the flash circuit? Sort of a more powerful burst nd a less powerful (but long range) sustained beam.

[nurdee1]

Cool.

I wonder if this would work to repel sisters. Also you should do a full blown step by step instructable. You might be able to get th camera flash part from an old disposable camera.

does this shoot

[xinistrom]

LOL yeh, it can blast holes through bank vault, i tried it

[dombeef]

I accidentally pointed it at the moon, now there is a small crater in it, what should I do?

[xinistrom]

nothing, not like it would be noticed anyway :D

[dombeef]

Did I forget to say that I hit where the Apollo 13 landed?

[freeza36]

"Houston, we have a problem" hehe

[l99roufs]

Hi wher could you get the velcro straps?

[Sandisk1duo]

ebay

[njkl44]

I dont understand this at all. u made a fancy thing that goes on ur arm that flashes...

[Sandisk1duo]

So what part don't you understand?
The arm part or the flashing part?

[Pizzapie500]

The capacitor popped in my face too! Do you think it's completely out of juice now? Cause' i'm scared to touch it.

[edm39c]

How much would it cost to make this?

[uhsnamih]

you should make a video of u fighting with someone with the same device.

[robertjames]

ware can i get all of this

[openroad12]

Please help me I've been stuck on this for weeks but I just cant figure out how to wire the flash part. Is the dc charging module the whole circuit board or just a small thing on it

[Chein]

The whole circuit board

[lioncour]

Hello and gratulations on an great intructable.

I was just wondering if the charging module draws current from both the battery sources?
Arent the disposable cameraes only 3 volt?

Best regards Anders.

[sekkei]

VOTED! I like it!!!
I should do it =)

[gitboxrhys]

Thanks this is really fun

[Ben Nguyen]

I am quite inspired by your innovative creation. This is a wonderful 'ible and I give you a 5/5. I plan on making this using my supply of capacitors from a coilgun, but I need to know where to find a circuit board like yours. Do you have any recommendations as to where I might find one?

[D00M99]

Excuse me;

I don't quite get where the flash and the charging source comes from. Can you explain it to me as simple as possible? Thanx.

[Chein]

The flash and the circuit that does the charging are taken from an old camera.

[D00M99]

Could you make this with one of those disposable cameras? Those are probably easier to get except I don't know if it's the same...

[Trilby]

That is a disposable camera...

[D00M99]

Oh. Sorry. I didn't quite understand.

[lug big lug]

ya, that is what he means i think, u can get those for free anyway. i made a "flashbang" using some of those....

[DeusXMachina]

Don't daze me, bro!

[Dr.Horrible]

This is genius! This would make for a great flash-bang effect, and of course it shouldn't be too strong to have lasting effects, right? Also, how much did it cost you to make this?

[Chein]

Thanks! I built it with junks lying around the house so I could not give you the exact cost.. but my guesstimate is no more than 10-12usd (given you already have a disposable camera to take apart)

[lug big lug]

The disposable cameras u can get free by asking someone at kmart or wallgreens or CVS for a used one, i got like (no joke) thirty for free and they thanked me for taking them.

[ekulmeekul]

Not really keen on strapping a 300V capacitor to my arm... :|

[Ward_Nox]

uou need to hide/disguise the batteries otherwise well done

[monkeys98]

Would a chinese container work instead of a microwave proof container.
