The Ultimate Nerf Vulcan Mod

We made a NERF chaingun fire about as fast as a 7.62mm M60 Machine gun. That's around 500 rounds per minute (RPM). We did two major modifications, increasing the voltage to the firing motor, and adding a round counter and a paint job.

The total cost on this hack was about $79

Step 1: What You Need

For this modification, you need the following:

Upping Voltage:

• 1 x Nerf Vulcan EBF-25 ($50)
• 2 x 9.6v battery packs
• 2 x 9.6v battery pack connectors (RadioShack)
• 2 x Alligator clips
• 3 x Wire nuts
• 1 x Ballpoint pen
• 1 x Chopstick
• 1 x Mana Energy Potion
• 1 x A hint of stupidity

Painting/LED Mod:

• 1 x LED counter from QKit ($18)
• 1 x Lever/Roller microswitch
• 1 x LED
• 3 x Momentary pushbutton switches
• 1 x 12v miniature battery
• 1 x Coil of wire
• 1 x Various paints

The round counter has such an Aliens look it almost makes me want to try and wrestle with whatever electronics kit that is; I bet it's an American thing though and not available here. .__.

Oh. Wait. This is all a giant con type advert for some lame mana potions drink. I totally fell for it. Well done guys, you're pretty much on par with Scientology with their Narconon and Guide to Better Living or whatever it is.

As for the 'contest', considering your gun is pulling about 120 RPM breaking 600 is ridiculous, you just want to have people talk about a silly contest all for some .. I would say cheap prize but knowing the prior health and mana potion drinks I've seen for sale around the place they're probably heinously overpriced, but still, a box of 12 dinky little drinks that're less than a mouthful and taste like death and AIDS combined, really?

Screw Instructables 'be nice' policy, this is idiotic.

You're telling me that Nerf's injection molded plastic toys are capable of 500 rounds per minute? I think you need to check your maths, it may have seemed fast, but that's almost ten rounds per second, something it took a hundred odd years for professional engineers to get firearms to successfully reach and billions if not trillions of dollars in research.

[npimpfellow]

Is there a way to complete this mod by vamping down the voltage (slightly) so as to get a rapid fire rate without risking burning out the motor? Any forum on this?

[Set271]

Wow, looks like fun all around. Even Sheldon couldn't say you're having fun wrong! Stay young and live forever guys...and gals of course.

[zeke34]

Ever thought of hooking it up to a power outlet? It'd only last for a few seconds but I'm sure you could get more that 500RPM out of it.

[nathanielg]

i used 2 18v batteries in series (36v) it fried the resistor inside so i opened it up ,removed the resistor, and made a solder bridge the motor lasted about 30 seconds before the brushes melted. It shot so fast that the bullet could not get a quarter of the way down the barrel before the next bullet fired so the gun just jammed

[ManaEnergyPotion]

Power outlets are AC, batteries are DC. Unfortunately, if we hooked it to a power outlet it would fry before it even got a shot off :-) Fun idea though. It would at least by arc-tastic

[CHOCOLATEmeter]

you would need, a variac and a full bridge rectifier,. put the rectifier on the output, and then crank it right up!!

[facilitator476]

If you wired a rectifier (or is it inverter) before the gun it would convert the A/C current into D/C. Though the 120V might be just a little too much for the gun to handle.

[jroberts23]

build a step down transformer? 1000 wire wraps on one side, 200 on the other. goes from 120V to 24V then add a rectifier. Should last more than 30 seconds if used in moderation. :P

[facilitator476]

GENIUS!!!

The best I could think of is to get a bunch if resistors and make a wish.

[taowyman]

you rock!

[taowyman]

how do you mod the newer vulcan?

[prodo123]

Why don't you rip a motor from a vacuum and stick it on the gun?

[Brown89]

nah it would only spark once maybe twice thats about it but from what I learned once you let the smoke out it stops working I hate it when that happens there is a way if you would really want to take the time to convert ac to dc but that requires a bunch more circuit crap and I dunno where to find the diagrams for that but if someone does do it definitely tell me about it I gotta see that

[CShaffer212]

Use one of those brick-transformer-adapters to convert from AC to DC, and put a space around the motor to hold some dry ice, or at least a fan and a heat sink!

SHADOW advertising. Zzzzzzzzzzzzzzzzzzzz. I actually thought this was real.

[albertkelley25]

very cool dude is there any way for it to hold more bullets

[Rebreg]

You should modifying the dart holder to hold more darts

[ralchin]

I cant find battery pack connectors ANYWHERE on the internet. Could someone pls give me a link? Btw i live in australia so i need it to have shipping available here.

[MSgt_JGC]

woops! sorry I read your comment half way dude sorry! :(

[MSgt_JGC]

dude go to radio shack, or go to the shack they have everything!

[diskincluded]

Try Jaycar, if there are any shops near you.

[~Meme~]

I live Australia too, so check hobby stores.

[MSgt_JGC]

WOW! I am only 13 and this guy is like 30+ and I solder like a pro.

[Go_Vikings]

Thats AWESOME!

[nof-z]

at our band camp, we have a nerf war, an now i know how to survive!!!

[will7917hero]

That is beast.

[Conrad717]

i know this post is old but could you modify a step counter to do this?

[awesomevampire]

hey,manaenergypotion
plz make a instrustable for a motion sensor vulcan
thnks

[Gr3at_Whit3_North_Guy]

In step two which sides are oosirive and which sides are negative?

[eichermacher]

What part started melting? Was it the motor or the batteries?

[Speedmite]

the motor. If you put too much energy though a motor the bushings will burn and it will stop working. The batteries might burn in a short circut.

[eichermacher]

Could you solve that by replacing the motor with a faster one?

[Speedmite]

Yea, but its more fun working around that. Like adding a super gearing system. But I could make this be such a beast if I used that 4 cycle multi weed wacker/edger/blower/tiller/ect with the air compessor..........

[Silence]

Hows about a cheap battery dremmel motor ? Those things and their gear boxes spin at upwards of 3000rpm and sounds like a dentist drill....

[agent harmsy]

What about an electric drill motor? :D

[codongolev]

I think that the darts would melt on the way out of the barrel....O_o

[Speedmite]

Drills dont get that hot. And I doubt the air resistance would melt the darts. But would the gears take it?
