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

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

[will7917hero]

That is beast.

[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.

[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.

[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

[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.

[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!

[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?

[cyberviper42]

If you think that then you need more time on a drill. I've had drills heat up to the point of burning me. The fact that i was drilling a 2" hole in 1/2" aluminum might have had something to do with that.

[codongolev]

that's what I was talking about. the gears would probably heat up a ton.

[Speedmite]

But I dont think the darts would melt.

[eichermacher]

 That depends on how close the darts move to the gears, and how long they are there.
I don't think they'd be there for long enough to melt, seeing as they are being shot.

[Speedmite]

Exactly. Unless of course, the gears are extremely close to the darts, and are on fire, and somehow are still working and not burning you. That would do it, and it would be epic, but it soooo wouldnt happen

[jkabiling]

also unless the gear is made of plastic. if the gear heats up alot, theres a pretty good chance that itll melt and break. idk about the darts tho. they might melt too depending on how close they are to the gear

[Speedmite]

Hehe..... Automatic flaming nerf dart gun.... Hehehehehe......

[eichermacher]

That gives me a great idea

[ErezYehuda]

Why do you guys even bother modding a Nerf gun? It almost seems like you could just build something from scratch.

[hellonfire30]

because its funner to work around it, and then belike YOU JUST GOT PWNED... BY A NERF GUN

[codongolev]

I think too that the idea is something along the lines of "I have a nerf gun, I have tools. what can I do to make my situation better?"

[Capt. Kidd]

But your vid said "Don't try this at home."

[pastaking]

Someone needs to do a spinning barrel mod for this gun. Something along the lines of this: http://air-sharp.com/octogon.htm

[taowyman]

where did you get the battery packs

[AlternateLives]

couldn't you just cut the thing open, do your surgery on the power terminals, then put the thing back together?

seems simpler to me than making a tool.

just a thought.

[mettaurlover]

If you've ever tried to open up a Vulcan, you'd know why it was easier to make the tool. Namely, the up to six inch deep screw wells, as well as the VERY breakable thin plastic parts inside it.

[AlternateLives]

I meant use a cutoff wheel to open it up, and a little superglue or epoxy to put it back together.

[Zeddicus.SB]

I found it to be much easier simply to hollow out the existing battery tray, then solder directly to the terminals of that... you're left with a tray that's easy to slide into place and one you can transfer to a different gun if you should happen to mess up lol
