Klingon Bird of Prey - Colors and Details
« on: December 28, 2017, 09:49:28 pm »
Hello again everyone.

For my next build, I'm going to tackle weathering and some lighting. After bouncing back and forth between the Klingon Bird of Prey
and a couple Star Wars kits, I decided on the BOP. I'll probably do some Star Wars afterward (maybe by the time TLJ comes out on blu-ray  ;D)



I'll be building in "cruise mode" and lighting the engines and torpedo launcher and see about the disrupters.

As for weathering, my plan at the moment is to try several things:
Pre-shade
Some post-shade
Chipping/scratching
Dry brushing
Wash
Pastels
Maybe some airbrush effects.

I'd like to practice with my airbrush a bit more to get subtle effects, so that may or may not happen on this build.

I also think I'll use acrylics, probably Tamiya, just so I don't have to wait until the apocalypse for all my various coats to dry.

It'll be several days before I can get started on this and get my supplies, but hopefully before the middle of January!
As always, feel free to chime in with ideas, suggestions, words of warning and what not. Let's hope this build will go a bit faster  ;)

Cheers,
Spencer

Good choice. You can never go wrong in weathering a Klingon ship.
No such thing as too much.
Will be following this to get ideas for mine.

Thanks Cameron. Hope I can deliver ...

Yep, it's what I first see when I think Klingon ... dirty and damaged  ;D

I had some time to look over the parts to see where the work should begin.
Lots of pics ahead. I'll be keeping a pretty detailed build log on this one.

I know there are more greeblies on the hull than the kit has, but I'm not going for screen accurate here, just something that looks nice.
I'll try adding a couple things here and there.



Gets me excited!


For inspiration, I'll be using some pics from a studio scale resin kit from NICE-N MODEL DESIGNS.
They have some nice closeups which I'll mainly be using for lighting (and some weathering) reference.
Just a general guideline. Link below:

http://www.nicenmodeldesigns.com/bird-of-prey.html

As usual, one of the parts was off the sprue, and it happened to be one of the cruise mode baffle plates, but no damage.
I think my model has warts!



There's a fair bit of flash, some subtle, some ... not so much.



The landing gear, which I won't be using, appear to be some kind of metal. Hmm.



One of the wing pieces has small holes in the surface, but aren't on the other three. Not sure about this.
I should be able to put some fiber optics and LEDs in the wing for the lights, more on that later.





The cannons look decent, but one is a tad bent. I won't be lighting these. I don't know of a way to do it without hacking and rebuilding.
I'll drill out the front ends a bit to create the appearance of a barrel.



Clear parts look good as well. Masking will be a chore, but I have options.



There are a good bit of suggested colors, a lot of enamels, but most of those are FS colors,
so it shouldn't be too hard to find acrylics that match or are close enough. Instructions seem thorough as well.





Decals are pretty nil, so yay! The baffles will have to be trimmed for cruise mode, but nothing too serious.
(I keep my decals in protector sheets away from climate extremes).




Okay, with that done.

The torpedo launcher and engines will be lit, and I think I can produce the lighting effects I want with an Attiny85 or maybe an Arduino Pro-Mini.
A firing effect and some very subtle flicker/fading on the engines. The fiber optics and window lighting will be static,
assuming I can get the windows opened up cleanly.

So really all I think I need is to run power (power and ground) and a wire for the pushbutton through the support rod.
I'm going to look around for a 3-channel headphone jack for the connection. That way the model won't have to be permanently attached to the base.

I'm starting with zero needed supplies and literally no model lighting experience at the moment, so it will be some time before I get any further. Until then.

Cheers,
Spencer

I had some more time to think about the lighting and I think I've conjured up a circuit using an Attiny85.
Note that I'm using an older attiny library and Arduino 1.0.5.

A pushbutton creates a torpedo effect and the main engines fade up and down slightly with even more subtle, faster pulsations.

Here is a short video, the LEDs are washed out, it's hard to make out the variations in the engine lights. They're much more visible in person.
I don't have any bicolor or orange LEDs, so I'm substituting here. What specific LEDs I use and their amount/placement isn't settled yet.
Timing isn't set in stone either. CLICK ON IMAGE TO PLAY



Here is a schematic of the circuit:




And the Arduino code. I copied the torpedo section from some refit code (done as a learning exercise) I wrote a while back.
===============================================================================

int enginePins[] = { 0, 1 };             // fading effect for main engine
int pushPin = 2;                         // pushbutton
int torpPin[] = { 4, 3 };                // torpedo ramp and flash
unsigned long debounceDelay = 1000;      // button debounce
unsigned long torpUpTime = 1750;         // torpedo ramp up time
unsigned long torpFlashTime = 200;       // torpedo flash time
unsigned long torpDownTime = 150;        // torpedo ramp down time
long double torpIdleBrightness = 10;     // torpedo idle glow
long double torpMaxBrightness = 255;     // torpedo max ramp brightness

// Bookeeping
unsigned long currentMillis;
unsigned long torp1DebounceTime;
unsigned long torp1Time;

void setup(){
  pinMode(enginePins[0],OUTPUT);
  pinMode(enginePins[1],OUTPUT);
  ------------------------------
  pinMode(pushPin,INPUT);                // this sets the internal pullup resistor
  digitalWrite(pushPin,HIGH);            //    on the pushbutton pin
  ------------------------------
  pinMode(torpPin[0],OUTPUT);
  pinMode(torpPin[1],OUTPUT);
}

void loop(){
  // get current time
  currentMillis = millis();
 
  // read pushbutton with debouncing
  boolean torp1Sensor = digitalRead(pushPin);
  if ((currentMillis-torp1DebounceTime)>debounceDelay){
    if (torp1Sensor == LOW){
     torp1Time = millis();
     torp1DebounceTime = millis();
    }
  }

  // torpedo effect
  // ramp up
  if ((currentMillis-torp1Time) < torpUpTime){
    analogWrite(torpPin[0],torpIdleBrightness+(torpMaxBrightness-torpIdleBrightness)/torpUpTime*(currentMillis-torp1Time));
    digitalWrite(torpPin[1], LOW);
    } 
    // flash
    else if (((currentMillis-torp1Time) > torpUpTime) && ((currentMillis-torp1Time) < (torpUpTime+torpFlashTime))){
      analogWrite(torpPin[0], 0);
      digitalWrite(torpPin[1], HIGH);
    }
    // ramp down
    else if (((currentMillis-torp1Time) > (torpUpTime+torpFlashTime)) && ((currentMillis-torp1Time) < (torpUpTime+torpFlashTime+torpDownTime))){
      analogWrite(torpPin[0],torpMaxBrightness+(torpIdleBrightness-torpMaxBrightness)/torpDownTime*((currentMillis-torp1Time)-(torpUpTime+torpFlashTime)));
      digitalWrite(torpPin[1], LOW);
    }       
    // idle
    else{
      analogWrite(torpPin[0], torpIdleBrightness);
      digitalWrite(torpPin[1], LOW);
  }
 
  // main engine fading effect
  int fadeValue = int(127.0+127.0/2.0*(1+(0.875*sin(2*PI*currentMillis/6000.0)+0.125*cos(14*PI*currentMillis/6000.0))));
  analogWrite(0, fadeValue);
  analogWrite(1, fadeValue);
}

===============================================================================

Will tweak this over the next couple days, go LED shopping and work on a pcb in Fritzing (yeah, I know ... Fritzing ...)

Nice!

Had one of these in "The Stash" for awhile now so looking forward to seeing you put this one together so I can pinch all your ideas. ;D

Looking at other people's build threads right now myself, at least ones that weren't wrecked by photobucket ...

-----------------------------------------------------------------
I ask these two questions below, but I'll put them up top.
Can anyone tell me where they get scratch building plastic online, opaque and clear
and a good place to order various diameter fiber optics in bulk?
Nobody sells scratch building styrene around where I live.
-----------------------------------------------------------------

Cleaning up and test fitting parts. Overall, I'm pleased. Will be a few places to fill, but nothing major.
Need to re-watch the blu-rays to get some screencaps.

Shopping around for supplies and also decisions, decisions ...

For the stand connection, I'm planning on a headphone jack, the bigger 1/4" variety.



The tricky bit will be the female connector because of space. Digi-key has some of interest, haven't checked Mouser yet.
i.e. https://www.digikey.com/product-detail/en/switchcraft-inc/L112BX/SC1563-ND/1832381

Which I think will fit in the main hull based on the schematics. Won't be a lot of clearance though. We'll have to see.

I found some red-white bi-color LED's on ebay (common cathode). Here's hoping that comes to fruition.
https://www.ebay.com/itm/3MM-Red-White-Bi-color-3-lead-Common-Cathode-LED-Pack-of-10-L303RWD/122891125425

Fiber optics and scratch plastic I'll have to get online. Anyone care to share their sources on that?
Was hoping for some fiber optic trees on clearance, but Walmart and the dollar stores already had their Christmas stuff
down and Valentine's day stuff up on Dec. 27. Nuts ...

Everything else lighting wise should be easy enough to get. Will dig into colors and paint soon ...

The hull windows are tiny, but I've seen many others open them up. Will just have to be careful. I'll fill those with canopy glue
after painting. Will test that first.



I'll have to hog out some of the inner plastic in the wings to get the F.O. to fit. One wing has some plastic molded out, the other doesn't. Hmm.
The bigger exterior lights might be small LEDs instead of fiber.



Still thinking about how to properly diffuse the lighting for the rear engines.

Now for a puzzle. Around the torpedo launcher is a detailed ring of windows. I think I can slice those open, but the sides of the inner torpedo insert
will cover those up.



I think I can carefully sand the sides of the insert at an angle so there is still a mating surface but can get some light through.


Read about it on this blog (in the comments somewhere in a later post):
http://bellerophon-modeler.blogspot.com/2012/05/round-2-klingon-bird-of-prey-wip-part-3.html

Still a while to plan and get everything. Into the unknown, I am ...

Cheers,
Spencer


P.S.
I think I have a control board for the engines and torpedo effect. It uses an Attiny85 and the capacitor and resistors are 0603.
I bought a smd soldering practice board a while ago and I went through it without problems, so I'm confident I can do it.
It's all based on the schematic in my earlier post.

No silkscreen to keep the size down.

If you are looking for big KBOP build threads here's mine over on AST. It took first place i n the 2014 "Make It So" contest:

http://www.allscaletrek.com/viewtopic.php?f=50&t=1949

I look forward to seeing how your build progresses. This was a fun kit to build.

I get all my sheet styrene and rods squares and angles off of ebay. You can get
bulk packs fo a fair price if you look around. I purchase all my fiber from
https://thefiberopticstore.com  Hope that helps.  I live in the middle of nowhere
so I get everything online.

Decided on my paints. Will be ordering them tomorrow.
I order most of my paints from Scale Hobbyist.

Started looking for Pale Green and found Model Master Acryl (enamel was discontinued?), which isn't my preferred choice.
Rather than play the game of mixing MM Enamel and Acryl coats, I saw Vallejo had most of the colors I wanted.

So, I will be going with mostly Vallejo Model Air, except for some detail stuff. I've been contemplating giving
these paints a go anyways, so my mind's made up on that. I also have a ComArt paint set that came with the
Iwata Eclipse Santa brought me. I'll try some of that too.

I could only find the regular Vallejo Model Color - Carmine Red for the red colored wing patterns, but it looks like a close
match and I found what looks to be a decent thinning formula for Model Color. I know it can be a bit tricky working with that.

Future will go over the paint to seal it in and protect it for the wash (planning on cheap artist oils and odorless Turpenoid for that).

More testing to do, but that's the game I play.  ;)

Cheers,
Spencer
