HERO LEVEL Fallout 3 Plasma Rifle FINISHED- Plus Pro Photo Shoot- First Post

Re: Fallout 3 Plasma Rifle

WOH! I always find props with lights like this awesome....what a beautiful prop.
 
Re: Fallout 3 Plasma Rifle

Anyone have any other forms of weathering they've found to be realistic? I kind of want ore texture on the rusted areas.. also the green frame of the gun needs some work.. I don't know yet if I want to represent oily corroded plastic or painted metal.. suggestions?
 
Re: Fallout 3 Plasma Rifle

That is amazing!

For weathering, I've used the Sophisticated Finishes with reasonable success. You can have copper patinas, a natural rust effect (with real rust), and a few others. I used the pewter kit on my PipBoy3K and the paint job turned out nicely.

Rust-O-Leum has a few options too:

Re: Fallout 3 Plasma Rifle

yeah I've seen some of the rustoleum stuff.. also looking into thinned oil paints as a final pass.. I'll check into the sophisticated finishes though thanks!
 
Re: Fallout 3 Plasma Rifle

NEEDED: SOMEONE WITH A BETTER UNDERSTANDING OF ELECTRONICS THAN ME

okay so I have a 9V battery, a (220, 1/4 ohm)resistor, and 3x 3V LED's wired in sequence. Worked fine. Then I added a toggle switch (the silver flicky switches like on airplanes) and suddely only the middle LED lights up..

All the LED's work when tested individually.. so what happened to my circut!?!?!

GRRRR.. on the plus the delay that caused made me consider redoing my 6 portholes which had a few errors in their constructon..
 
Re: Fallout 3 Plasma Rifle

What happens when you wire in two LEDs instead of three? It's very odd that it's the middle LED that lights up. If you move them around, is it the same one that lights?

Here's one fact: you barely have enough potential (voltage) to drive the circuit. You have a 9V battery (which is probably closer to 8.7) and three 3V LEDs (which can be anywhere between 2.7V and 3.3V). V = Vs - Vf = 9 - 3 - 3 - 3 = 0.

Now here's a guess: the switch may have a drop of 0.1V or less (cause it's not a perfect conductor) and that's enough to tip the scales. The power requirements of that middle LED might be just that much less than it's two brothers enough to light up.

You'd be better off wiring the LEDs in parallel after the switch. The downside to that is you use more current and drain the battery faster.
 
Re: Fallout 3 Plasma Rifle

okay yeah that's what I was thinking wire them in parallel.. the only thing that still doesn't make sense (at least to me) is I tried it again with a 12 V battery pack (9v plus 2xAA) and only one went on still!! My problem i think is I added the lights to the assembly prematurely.. next time I'll do the entire wiring, test, and then worry about installation.

Thanks though I'll try that.
would I need to put a resistor on each LED line or just one after? the battery?

sorry I want to aspire to greater electronics knowledge but just haven't had a chance yet heh..
 
Re: Fallout 3 Plasma Rifle

How did you have the AA batteries wired in? If they were in series that should have produced 12V. If you wired the AAs in parallel with the 9V you'll still have only 9V.

You should have a resistor per LED. The reason is that electrons are picky and will choose the path of least resistance. But a resistor is a voltage drop and will guarantee that current will flow through it inversely proportional to the size of the resistor (the math can get a little funky). If you have to drive lots of LEDs, a combination of parallel and series works nicely. Say you have to drive six 3V LEDs on a 9V battery. You can split them up into three sets of two. This way the effective voltage is 3V across the resistors and each current stream powers two LEDs.

If you haven't seen this yet, I recommend checking it out: Light Emitting Diodes (LEDs)
 
Re: Fallout 3 Plasma Rifle

Congratulations on the rifle....simply amazing.

Made me want to boot up FO all over again!
 
Re: Fallout 3 Plasma Rifle

I LEARNED A LESSON...

When you feel a component of your prop is visually.. weak.. do something about it. sometimes an underestimated component can be a slight detraction.. or can be one of the visual highlights...

I was never happy with the old portholes.. not beefy enough, so I reinforced them with epoxy putty.. still no.

So since my wiring if going to have to be redone, here is the also redone portholes.. Now a somewhat crappy looking piece of the prop has become the visual highlight it should be.

Enjoy!

the depth is created through the use of 1/4 inch thick acrylic.. makes it look like reinforced glass instead of floppy thin stuff

OOOHHH SHINY!!! like I said I think this is quite an improvement over the old version.
(dry assembly, the nuts are a little out of place.. )
This is why you must develop each piece of something to it's full potential. Working with plastics for nice finishes for chrome is so much easier than dicking around with MDF.. also much more expensive :D
 
Re: Fallout 3 Plasma Rifle

aww I can't see you're latest pics dude (links wrong?) :(... the build looks amazing so far!
