Summary

I'm sharing my current LED / Arduino / Neopixel Nerf Barrel project while it's still in process. The 3D printed barrel is quite usable as-is, and fits any modulus / stryfe barrel.

You will see the design is complete and I have prototyped it to get it working, however a couple damaged neopixels is causing me some assembly rework. I decided to publish before I loose steam.

The bill of materials beyond the 3D printed barrel is below:
1x round (18.3mm hole) rocker switch
1x arduino pro mini or equivalent (5v logic version)
1x 470ohm resistor
1x 10microF capacitor
13x 5mm X 5mm surface mount neopixels
1x 9v battery
1x 5vdc regulator

Print Settings

Printer Brand:

Wanhao

Printer:

Wanhao Duplicator i3 Plus

Rafts:

No

Supports:

Yes

Resolution:

0.2

Infill:

100% on battery door and 30% on barrel


Notes:

i had good results printing the barrel sticking up from the bed (180mm z height), and printing the battery door on its exterior face.

For the battery door, the battery clasp mis-printed until I added a 6-wide brim 1-layer high.

Post-Printing

1) Clean-up

1 - snap off the barrel support structure from the end that connects to the nerf blaster.
2 - clean up your supports from inside the battery/electronics compartment.
3 - clean up brim from the battery door

2) Assemble electronics

1 - connect the 9v battery to the 5v regulator
2 - connect the toggle switch in series with the power
3 - solder together the neopixel string at 22mm spacing (outside to outside of the 5mm square neopixels)
4 - install a 470ohm resistor on pin 6 of the arduino and attach the data-in line from your neopixels
5 - install a 10microF capacitor across the +/- leads that supply power to the neopixels. for this short run, I power them off the same power rails that provide 5v to the arduino.
6 - snap in the 5mm neopixels into the holes in the barrel.

3) program the arduino

I will share an final code that has the LED patters programed later, but this starter code will get you going. Remember to update the NUMPIXELS variable.

// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// released under the GPLv3 license to match the rest of the AdaFruit NeoPixel library

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
  #include <avr/power.h>
#endif

// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1
#define PIN            6

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS      13

// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals.
// Note that for older NeoPixel strips you might need to change the third parameter--see the strandtest
// example for more information on possible values.
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

int delayval = 20; // delay for half a second
int peakval = 25; // set peak color value for fade
void setup() {

  pixels.begin(); // This initializes the NeoPixel library.
}

void loop() {

  // fader routine (red)
  for(int i=0;i<peakval;i++){

      pixels.setPixelColor(0, pixels.Color(i,0,0)); 
      pixels.setPixelColor(1, pixels.Color(i,0,0)); 
      pixels.setPixelColor(2, pixels.Color(i,0,0)); 
      pixels.setPixelColor(3, pixels.Color(i,0,0)); 
      pixels.setPixelColor(4, pixels.Color(i,0,0)); 
      pixels.setPixelColor(5, pixels.Color(i,0,0)); 
      pixels.setPixelColor(6, pixels.Color(i,0,0)); 
      pixels.setPixelColor(7, pixels.Color(i,0,0)); 
      pixels.setPixelColor(8, pixels.Color(i,0,0)); 
      pixels.setPixelColor(9, pixels.Color(i,0,0)); 
      pixels.setPixelColor(10, pixels.Color(i,0,0)); 
      pixels.setPixelColor(11, pixels.Color(i,0,0)); 
      pixels.setPixelColor(12, pixels.Color(i,0,0)); 

      pixels.show(); // This sends the updated pixel color to the hardware.
      delay(delayval); // Delay for a period of time (in milliseconds).

  }

  for(int i=0;i<peakval;i++){

      pixels.setPixelColor(0, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(1, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(2, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(3, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(4, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(5, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(6, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(7, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(8, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(9, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(10, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(11, pixels.Color(peakval-i-1,0,0)); 
      pixels.setPixelColor(12, pixels.Color(peakval-i-1,0,0)); 

      pixels.show(); // This sends the updated pixel color to the hardware.
      delay(delayval); // Delay for a period of time (in milliseconds).

  }

  delay(500); // pause dark before relooping
}
