Nerf Aliens Pulse Rifle Build

I realize I'm late to the party .... but is/are there any online tutorial resource(s) for how to model using styrene?

:confused
 
youtube has a few tutorials, but if you need to know anything particular ask and some 1 will tell you the answer :)
Hey Thanks !!! . . .

I guess I'm just looking for some tutorial (preferably visual) guidance on the "how-to" basics for modeling with styrene. If you know of any particular YouTube videos, might you be able to guide me/us in the right direction?


:)
 
well 1 tip don't try cutting styrene with a knife scribe the cut line and flex and snap the plastic, you can keep scribing the same line to you "cut" through but the flex and snap method is mostly used.
 
Hi there.
I'm also a little late to the party, but after stumbling onto this thread during a random internet wander I decided it was far too long since I'd built anything and this was a great project.

So first off I need to say thanks to quest for putting the pictures up, and also for the plans - very generous and I hope it's given you pleasure to see all these child projects from your original master.
Also to others who have posted their builds and shared ideas, many of which I've taken note of.

I've now got all the NERF parts needed (and became rather too knowledgable on what "component" parts for NERF guns go for on eBay!) and have sourced everything else I need - I was actually planning on getting my sheet from 4D Model Shop so it's nice to know someone else has used them.

Like many of you, once I started to look at this I decided I wanted my LED display to be lit. I found some information while googling around and figured I could set 2 digits to show 95 and have them come on when a clip was inserted - a simple contact switch.
Then whilst looking for a way to wire up 2 digits without needing 14 wires I came across something I'd heard of but had never really investigated - the Arduino.
For those who're not aware, it's basically an electrical control circuit (which I'm sure are used a lot on this forum), can be run by battery and the main point that grabbed me - is programmed via a PC/Mac in a variant of the C language. I'm a software developer by day, and suddenly my ambitions for a lit display grew - a lot!

So after some playing, for the price of an Arduino (~£15 on eBay) and £10 or so of components I've written a control script (which are called sketches) which does the following:

2 microswitches, 1 for the clip and 1 for the trigger. 1 touch switch on/near the circuit for counter mode selection.

There are 3 counter modes: Single, Full auto and NERF. These can be cycled by pressing the touch switch and are indicated with a 1, F or n respectively on the display for 2 seconds when changing. The selection is retained when the unit is powered off.

They function as follows:
Clip out
- Display shows 00
Insert clip
- Single and Full auto, display shows 95. NERF, display shows 12 (assuming the butchered clip takes 12 darts)
Pull trigger
- Single and NERF, display reduces by 1 for each pull no matter it's duration
- Full auto, display rapidly ticks down as per the movie until the trigger is released.

At the moment it's all working but pieced together on a breadboard (temporary circuit board with push in wires) while I'm developing it but I hope over the next few weeks to solder it onto stripboard, use some multi-pin connectors and figure where it can be placed in the gun - which I should probably also start working on! The Arduino has rather taken over the project!

Once it's done and I know it can all fit I'll post the details here: circuit diagrams, photos and of course the sketch for anyone else who wants it.

For now, if you have any ideas on how the functionality could be improved or added to, please say.
An option that is possible, but I can't really justify paying out for at the moment, is to buy an audio "shield" (the names for add on circuits for Arduino's) which would be loaded with audio clips of loading,firing,etc add a a speaker and play them at the appropriate moments.

The nice thing about the Arduino is that if I mount it so it's easily removed (ie, not hot glued!) it can be added to/reprogrammed at any time. Speaking of which, any ideas to those who've built the upper casing as to where I can fit a circuit board that's 7 x 5 x 1.5 cm - I'm thinking on the inside back of the upper case, then run the cables through the top of the stock (where it doesn't slide all the way shut) with snap connectors for the wiring. Thoughts?

Again, I want to say thanks to everyone who's contributed to this thread - the sharing of ideas and information is truly wonderful.
 
You could try mounting the board in the "front" grip part that's in front of the grenade launcher trigger. my 1st model has that part that i can take it off its not glued up solid.
 
wow! awesome first post, welcome to the RPF!
I've been toying with the idea of getting the Arduino for my Lawgiver but haven't got round to it yet..perhaps your idea will make it double worth getting one!!

maybe I could harras you with some questions about that project at some point :D

Make sure to post your build progress here somewhere, we're all learning!

Respect

I second the welcome, and great first post badkarma :thumbsup


I thought I'd try my hand at an Arduino too (Arduino Pro mini 16bit 5v)

I've only touched on the language so far, so it's a bit beyond me for now, but I'm slowly working my way through to a point where I can focus on that part of it :thumbsup


And to top it off, I have an ISD2540 multi addressable rec/play chip I need to test out (man was it hard finding these on their own and not part of a module of one kind or another).

From the data sheet, I have 3 PWM outputs, so it just covers both displays and the ChipCorder (unless I can daisy chain the displays, then I could use the free PWM for some muzzle LEDs).
 
Nice addition badkarma! Will keep an eye on this to see how it all turns out :)

And yea, I definitely get a big thrill every time a new nerf pulse pops up. Makes me want to go back and make another one ;) At the very least I want to go back in and add a real round counter one day.
 
Thanks chaps

That's a cool idea for placing the Arduino in the front grip, would need a lot less wiring all over the place.

I'm more than happy to help anyone out with code - with most languages I've not used before I find the best thing is to write the logic of what I want in comments using pseudo code/plain English, then head off to the docs/google to turn it into code that compiles. Once you can write in a couple of languages then it's all syntax after that, the logic rarely changes.

I went for the Uno for reasons of ease it being my first time with electronics (since A level physics about 25 years ago!) - with the built in 5v converter it's plug and play with USB for uploading sketches and a power plug for a battery/pack to make it instantly portable but you sound like you know all about electronics Canobi. I do like the compactness of that mini though :)
 
well it really need to be in 2 halves so the gun can be taken apart if needed, will add more detail to it later, would have been easier to make a solid 1 but i like to fiddle with the nerf guns :lol

It looks like 20 years as a solder monkey has finally started to rub off :lol Electronics has been more prominent in my hobby lately, so I'm taking the time to learn as much as I can :thumbsup

I'm looking forward to booting this little baby up :)
 
Don't mean to hijack this thread but I'm working on a Dredd 3D Lawgiver and am kinda stuck a bit with recreating this bad boy...

I think (according to my research thus far that I can maybe do it with an Arduino nano or similar and this...

Just thought while we're on the subject of sexy electronic displays...

Rather than totally derail this thread you can PM me if anyone has any light to be shed on this poor mans dilemma :$

and now back to normal service....PULSE NERFS!
