New to It all:) Fallout Project

Projects General Guidance

Hi everyone:)

Recently i started my yet another cosplay project which is Power Armor from Fallout Tactics (Midwestern Power Armor)

Although this is not a problem:)
Along with the armor Im planing on making a gun although i should call it THE GUN which is M72 Gauss rifle I dont want it to be YET another game replica:D thats why i decided on making it fully operational plastic BB gun with some extra features. (maybe)
first which will be audible sounds pulled out of the game recorded on two of those tiny Recordable Voice Module one connected to trigger to make a shooting sound and one connected to mag for reload sound

Second which is beyond my understanding of electronics is barrel which will light up before taking a shot and when taking a shot coils on barrel will power down (fade function to be used here)

I would like it to work like that

  1. flip main switch located somewhere on the side of a gun
  2. after 5 sec`s first coil (end of barrel) stars to light up and light fades in lighting up rest of them one by one this should take about 8~10s
  3. lights stay on until shot is taken
  4. when shot is taken lights fades out in 0,5~1 sec from last coil (closest) to first (end of barrel)

there should be 48 LED`s all together connected in sets of 6, battery pack, and battery charging module, battery indicator could be analogue Voltage meter or LED one, obviously Main switch that will cut the power from controller and input tactile switch for trigger

there might be a slight issue of size as every part will be solid cast in polyurethane resin

here are some pictures how i want it to look like

Any ideas how could I achieve that?

And most important thing how to properly assemble them:)
PS. I know how to use soldering iron

for now my simple schematic`s look like that

which part do you need help with ?

I just posted to another person with a suggestion that may be useful. Side emitting plastic fiber-optic strands could be used as light rings. Various lengths and thicknesses are available, and it is very flexible. Only one LED is needed per ring. Search web sights that have good product descriptions and project examples for ideas. Getting the rings to pulse in sequence (or other effects) takes very little programming. A power indicator could be made from several short (~1 inch) pieces set side by side, and light with individual LEDs in sequence. End emitting fiber-optic strands could be used for other effects too.

given the amount of led's you're thinking of running, you might need to do something like having a arduino digital PWM pin being amplified by a small offboard opamp or two transister amp to drive the LED's as the arduino's can only deliver something like 40ma per pin. have one of these set up for each ring.

I assume you will be going to a convention suck as comic con or armaggeddon during the daytime with it. So if you have led's running you will need quite a few for the light effects to be visable outside. Depending on the diameter of the ring probably at least 8 led's (or more).
(this is based on my experience of such events and my various costume prop designs)
