Title: Klingon Bird of Prey - Colors and Details
Post by: Spencer 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)

(https://farm5.staticflickr.com/4594/39332829342_944f59d2ff.jpg) (https://flic.kr/p/22VH2Q3)

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 (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!

(https://farm5.staticflickr.com/4739/25508129458_d4be5b7812_z.jpg) (https://flic.kr/p/ES4Qcu)

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

(https://farm5.staticflickr.com/4733/27600564679_68ac138362_z.jpg) (https://flic.kr/p/J3Y7hP)

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

(https://farm5.staticflickr.com/4592/38669367104_9d00176850_z.jpg) (https://flic.kr/p/21V5BBW)

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.

(https://farm5.staticflickr.com/4587/38499925045_42224d7b46_z.jpg) (https://flic.kr/p/21E7bp8)

(https://farm5.staticflickr.com/4686/24512501137_b0e8b0cfb0_z.jpg) (https://flic.kr/p/Dm5YzX)

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.

(https://farm5.staticflickr.com/4647/27600544709_9ee05c0c58_z.jpg) (https://flic.kr/p/J3Y1mv)

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

(https://farm5.staticflickr.com/4590/27600497259_4842111a7e_z.jpg) (https://flic.kr/p/J3XLfp)

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.

(https://farm5.staticflickr.com/4687/27600520679_3f4771ba5e_z.jpg) (https://flic.kr/p/J3XTdc)

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.
===============================================================================

    digitalWrite(torpPin[1], LOW);
    } 
    // flash
    else if (((currentMillis-torp1Time) > torpUpTime) && ((currentMillis-torp1Time) < (torpUpTime+torpFlashTime))){
      analogWrite(torpPin[0], 0);
      digitalWrite(torpPin[1], HIGH);
    }

  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 ...)

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.

(https://farm5.staticflickr.com/4733/39422136112_b2a1cd7b86_c.jpg) (https://flic.kr/p/234AKBW)

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 (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 (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.

(https://farm5.staticflickr.com/4597/25582738868_1b84a646e7_c.jpg) (https://flic.kr/p/EYEdYC)

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.

(https://farm5.staticflickr.com/4736/38744741884_df644f656c_c.jpg) (https://flic.kr/p/222JVV7)

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.

(https://farm5.staticflickr.com/4645/25582749958_f727b98dee_c.jpg) (https://flic.kr/p/EYEhgQ)

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.
(https://farm5.staticflickr.com/4732/39453223041_71bdaccf65_z.jpg) (https://flic.kr/p/237m5Ft)

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.

Decided on my paints. Will be ordering them tomorrow.
I order most of my paints from Scale Hobbyist (https://www.scalehobbyist.com/).

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

LOL!

Of possible interest to you Steve are some small carbide like bits on loan from a friend, he said that Micro-Mark sells them too.
They might make the torpedo windows a bit easier to clear out for me. Will probably have to buy a set if it works out.

My red-white bi-color LEDs showed up in the mail this morning. Video below. You can see the red diode is clearly off to one side, but
that shouldn't be a problem by the time it get's jammed into the torpedo housing and the clear insert put over it. Click to play.

The pcb should be on it's way to fab soon ... but will still be a couple weeks.

I also ordered a couple switches. A yellow latching one for power and a red pushbutton for the torpedoes.

And some wrapping wire from Jerry over at http://hdamodelworx.com/ (http://hdamodelworx.com/)

No ideas for the base yet, but there will be a simple 5V linear regulator circuit in there.

Still have to order the rest of the LED's and fibers ...

Been a couple days since an update. Not much to say though.

My 1/4" female headphone connector arrived yesterday. There's enough clearance for it to fit, but I'll have to fill in the original
mounting hole, drill the new hole forward a bit and enlarge. Waiting on my scrap styrene to get here to do that.

Also got a 2.1mm DC power connector. You'll be able to see some threads on the connectors for this build, but I
think it'll add the the utilitarian, Klingon aesthetic.

My 0603 parts arrived for the circuit board. It's really just a sample book of resistors and capacitors from China, but they should do the job.

A lot of of other things should be arriving on " ... don't tell me, Tuesday?" and I should have nearly everything except the circuit boards by the end of the week.

This is definitely one of those models where you have to have a lot planned out before you get into the thick of it.

Those needle burs look like they would be small enough for just about anything! But they do look like diamond tipped burs used for cutting glass rather than plastic. Have you used them yet? How did they work?

Is your 1/4" female headphone connector gonna be your power supply connector/display stand?

Keep going! Learning lots!

Thanks Steve.

First:
Yes, the headphone jack will sit on top of the support tubing and plug into the model.
It's a stereo jack for 5V, ground and the pushbutton line. Here's what I'm using, still on it's way from Adafruit:

https://www.adafruit.com/product/1803 (https://www.adafruit.com/product/1803)

Here's the female connector I got from digi-key:

https://www.digikey.com/product-detail/en/switchcraft-inc/112BX/SC1317-ND/1217816 (https://www.digikey.com/product-detail/en/switchcraft-inc/112BX/SC1317-ND/1217816)

Second:
Here's a pic of my first go on the torpedo emitter housing. I used a #80, yep 80, bit to drill out a few holes as best I could, then,
I used it as a file to "saw" out the gaps between and do basic cleanup of the burs. Not ideal and slow, but it works.
This is about an hour of work for me being extra careful not to break the bit. My big question now is, what do I fill them
with. Clear epoxy or acrylic before paint and assembly, or canopy glue at the end. I'm not sure which will look better. Hmm ...

It's a bit rough up close, but when you step back a typical distance it looks pretty clean.
(https://farm5.staticflickr.com/4599/38869909264_7edd830a3a_c.jpg) (https://flic.kr/p/22dNrPo)

After digging around Micro-Mark, I think I found the actual bits in question. They're called diamond reamers. My buddy gave me this set to try.
He uses them to chew through clear acrylic.

https://www.micromark.com/3-piece-Diamond-Reamer-Set (https://www.micromark.com/3-piece-Diamond-Reamer-Set)

I used them to enlarge the window a bit on the outside and inside. Inside especially to give light a better chance to hit it. It whittled
on the plastic without hesitation. They're not quite big enough to get into the smaller torpedo windows, but should work on the bigger ones.
That's all I can say for now.




Some of my styrene, my paints and LEDs arrived today, so yay! I can get back to drilling later in the week.

Post by: Spencer on January 10, 2018, 09:39:38 pm
Waiting on my fiber optic to get here. PCBs were shipped today!

More work on drilling out the torpedo ring. The small drill bits, followed by a bit of smoothing by the reamers is working.
But, I decided to cement in the torpedo insert before doing the bottom windows.

The problem here is that the inset completely covers them, plus the plastic of the "ring" is much thinner here and the windows
need drilled at a pretty oblique angle.

Still a bit of cleanup to do.

I used Tamiya extra thin cement to attach the insert, putting it in every seam I could see.
That way, it should be a bit easier to open up the lower windows, even if i drill into the insert a tad.

Compared to these, the rest of the drilling on this kit should be a breeze!

Sorry about the camera here, it overexposes and makes the windows look rougher than they really are.

I don't know how you guys drill out windows for TNG ships, I think I'd go nuts!


I'm still debating whether or not to tear down the disruptors and rebuild them with some tubing like i've seen in other builds.
Never tried anything like it before. Still a fews days away from that though. Need to sleep on it.

Cheers,
Spencer

Spencer, your drill outs look very well done! Nice work!

As for the disruptors, as you may know, there are metal gun-barrels available on the web. They are primarily used for WWII airplane and armour builds. I'm not sure of the scale you would need nor if you could find something suitable matching the disruptors but after a quick search I found this website. http://store.spruebrothers.com/category_s/1949.htm It's just a suggestion - feel free to find something to your liking - just thinking while typing.

The TNG drill outs - well, once you find the right tools... ;)

Looking great!

Qapla'!

@Steve. I thought about gun barrels, but I ordered a 1lb. bag of assorted K&S metal tubing, to isolate the torpedo LED
and have some lying around. I also got a bag of assorted evergreen tubing for the fiber optics.

I think there should be enough metal tubing to do the job. My worry is getting the barrels straight if I go that route.
Would have to come up with a jig or template of some kind. Haven't put much thought into it yet.



I had some time over lunch to get the rest of the torpedo windows drilled. Putting the insert in was definitely the right decision
as I had to go through a good chunk of the support piece. But it's done and the Tamiya cement did its job. A big mental hurdle passed.

I think I'm going to fill these in with canopy glue, tinted with some red food coloring, after all the painting and weathering is done.
They're small enough to where I think that should work. I can always hit them with some clear red Acryl later if the tint isn't enough.

Well, most of my stuff arrived early, and I made a decision.

I'm going to try and rebuild the disruptors with metal tubing. I'll be ale to see tomorrow whether I have enough of the right sizes.
If worst comes to worst, I'll just have to go get another kit and use those pieces stock (and sell the rest for parts). I thought about
sending in the form to Round 2 to buy replacements, but it would be more expensive and the last time I got a replacement
part it took 5 weeks.

So, I had to rethink my lighting. If the disruptors are going to be lit, then they will have to fire. They just ... they just have too!  ;D

The problem is that I would need two pushbuttons, but only have enough connections on my headphone jack for 5V, ground and
one pushbutton. I was using two of the Attiny85's pins for the engines, but I have some bright wide angle white LEDs that I'll be using
and I might be able to get away with one, or hook up a transistor circuit. That leaves the second pin open for the disruptors, but still
one pin short for another button.

I thought there must be a way to do this, then I found a few places online with code to make push-buttons multifunction.

I've written some code such that when I push the button, it fires the torpedoes, if I press and hold, it fires the disruptors in random
bursts for 8 seconds. I'll post my code later since it's a bit of a mess right now. I'll probably have to hook up a transistor circuit for
the disruptors too, but no biggie. What was supposed to be simple lighting has ... well, you know.  ;)

I had some time last night to work on ideas for the windows. I've seen a few use canopy glue after all the painting
and assembly is done, but others suggest Micro Kristal Klear. So I tried both.

I took some canopy glue and mixed it with a drop of red food coloring and used a toothpick to get it into one of the torpedo
windows.

(https://farm5.staticflickr.com/4658/39685424441_b0a4be23d2_c.jpg) (https://flic.kr/p/23sSb4T)

After letting it dry a few hours, i wasn't too thrilled. Part of the window was clear red, the other half dried opaque.
No pictures of that, camera battery was dead.

So I dug it out and tried Kristal Klear instead. It seemed a bit thicker and I only mixed enough red coloring to turn
the glue reddish pink.

Leaving it overnight I got this.

(https://farm5.staticflickr.com/4767/27907169019_30b5a346c6_c.jpg) (https://flic.kr/p/Jw4x5x)

The window looks a bit smaller and dimmer, but more in scale I think. There's also a noticeable deep red color
when the window isn't lit. The Klear did shrink a little into the window, but not nearly as much as the canopy glue.

What do you all think? The only other thing I could imagine doing is filling with clear acrylic, which I would have to
get.


Will be working (thinking) more on the lighting over the next couple days.

I went through my 1lb. bag of assorted tubing and found enough of the right things to rebuild the
disruptor barrels, I think.

(https://farm5.staticflickr.com/4664/38987884024_ffbf4e2f8a_c.jpg) (https://flic.kr/p/22pe6AY)

The main brass barrel is just slightly bigger than the kit molded one, so I'll have to be careful not to hog out
too big of a hole for the middle piece that connects to the curved barrel. I'll probably have to use JB Weld to
attach metal to metal. The little cannons will fit 1.0mm fiberoptic and the bigger cannon 1.5mm.


Here is the control board, fabbed from OSHPark, front and back with an ATtiny85 plopped on top. The resistors,
and capacitor, will be 0603.

Tanks manu.


Well, I'm still waiting for a couple things. Remembering to need "this and that" and so on ... Hopefully next week I can start in earnest.
So, this has given me some time to think about weathering, watching videos and reading up on it, and decided to share some of my thoughts on my
intended process.

- I'll be doing a pre-shade with black paint on the recesses before the main hull color.
- A post-shade by spraying more of the main hull color in the center of the panels. Tone it down with a blending if I have too.
  Then do the same with all the accent colors.
- A lot of the heavy streaking and similar effects I'll attempt to do with paint, either with an airbrush
  or brushed on thinned paint. Dry brushing highlights, wear and doing chipping will be done here too.
- Then a coat of Future, to seal in the acrylic and to put on and seal in the decals.
- A couple washes using odorless turpenoid dirtied up with a touch of artist's oil paints.
   (I've read in several places that turpenoid will work as long as the Future is completely cured)
- Then another coat of Future to seal that in.
- A light coat of some kind of flat so the pigments stick a bit better. I bought some Tamiya weathering pastels, but might grind up some pastel chalk to try too.
- Then some final light coats of flat to seal it all in.

I might be getting a bit ahead of myself here. But, it does give me some time if you all have any suggestions or ideas. I think this will work though.

Cheers,
Spencer

Post by: MiniMadnessR53 on January 21, 2018, 10:07:15 am
What I am did ( cause im building the same kit lol ) is sprayed the main hull parts with a  black primer, this does a few things, Light blocking, and makes the green that you will put on the hull look a lot better. I have been happy with what I have done so far.

With regards to the lighting - I like what you are doing. Since I am just getting into kit building, I don't have the proper things at the moment to build my own boards ( You would think I would considering I used to build robots from scratch in Highschool haha ) So I purchased the Madman Lighting Kit for the model. The question I had was,
      - How are you laying the wires and lights in or what is your plan when you get there.
I am at a stand still because I haven't got the slightest idea on how to get the wings lit.

This is what it looks like currently. The radiator baffles need to be lightened up a bit as I feel they are too dark.

Post by: Spencer on January 21, 2018, 01:50:52 pm
@MiniMadnessR53

I can see where the black might help with the green color a bit (I know that's true for reds).
I'll have to think about it.

For lighting, I plan on using wire wrapping wire I got from Jerry over at HDAMODELWORX because it's small.
e.g. http://hdamodelworx.com/Wire-Wrapping-Wire-AWG28-Black_p_19.html

For main power wiring and where I'll need more current handling, I'll be using some 22 gauge wire. The wire will probably be
tacked down with CA glue and accelerator.

For window lighting, I'm using some soft white, high brightness wide angle LEDs from Lighthouse LEDs
https://lighthouseleds.com/catalogsearch/result/?q=5MMFLATTOPLEDWARMWHITE

For placement, I plan to put a few inside around the windows, and also use them for the engines, since the clear part
will be painted the right colors. I'm going to trim and bend the leads and use CA glue or low-temp hot glue to secure them in
place at roughly the right angels.

I'll also be using the same LEDs for lighting fiber optics that will run into the wings for the "spotlights" and other external lighting.
The only way I know to light the disruptors is to tear them down and rebuild them with metal tubing. You'd have to be a real black-belt
to try and drill out those plastic cannons to run a fiber. A green LED should be able to squeeze into the cavity behind the guns. Digging
out some trenches inside the wings is how I plan to do it.

For the red "boxlights", I'll be using some red LEDs and a sheet of red styrene that luckily came with my Evergreen odds and ends bag.
I'll have to build small light boxes for that.

For light blocking, I'm spraying the inside black, then maybe a layer of silver, followed by white to get more diffusion and brighten things up.
That plus primer and color on the outside should deal with most light bleed.

I'll work on some assembly, light-blocking and greebles soon, but the disruptors have become my priority now that I have what I think is a decent plan.



This also arrived in the mail Saturday. It's a socket for using SMT parts on a breadboard.

I had a sketchy way of programming the ATtiny85 on the PCB, but these sockets spoiled me when I was a student, so I broke down and bought one.
Should be making use of it in the future. Here's where I got it for those interested.

Thanks Scott. I try to be thorough.

Learning as I go on the Klingon BOP.

Such as ...
1.) My razor saw can handle cutting brass and aluminum tubing.
2.) I only have one set of snippers than can actually cut music wire.
3.) I can solder the two together with my trusty Hakko iron and rosin core solder. Still
might wind up using just CA or more likely JB Weld.

(https://farm5.staticflickr.com/4653/39037365675_02c8640376_c.jpg) (https://flic.kr/p/22tAGLT)

I'll be using 1/16" aluminum tubing to run the length of the cannons to put 0.75mm fiber optic in, followed by telescoping
outer layers of brass to act as spacers between the plastic bits. The tiny "barrels" will be music wire

First main cannon built and installed. MUCH more confident now, but sadly, it's all I can do until Tuesday or so.
CA glue of various thicknesses and accelerator were used to glue everything together.

Thanks Steve!



The disruptors are done. Some cleanup and I'll be ready to tackle the next thing, just not sure what that is yet  ;D
Gonna give my fingers a rest. A shoutout to trekriffic (Steve). His work on the disruptors were an inspiration for these.

I changed the secondary disruptors a bit. I'm working on a better drawing for my own reference as well and can put that up when it's done.

Thanks. Here's hoping I can deliver  on the rest of the build ... :-\



Thinking about other greebles and color, going through some photos and screencaps for a rough reference.

Here's what the kit suggests for color (roughly)
A little "meh" compared to the studio model, even without considering weathering. Needs some more
accents here and there, and more metallics. Will have to work on it.

Also,

I noticed a big pop mark on the front of the ship, and what looks to be
more Romulan than Klingon writing on the starboard side?

I believe the original idea was that it was supposed to be a Romulan BOP
and Kruge was a Romulan, then he became a Klingon who stole the BOP,
and then the ship became Klingon ...
Never noticed the writing before though.

Romulan is similar  There are two different fonts for it .
The klingon script is actually English letters. There are a couple
more fonts that are klingon letters.

Here i am the expert in alien languages. LOL

Cool build by the way. I stealing ideas for mine.

I put some more accents on the model, some more Light Ghost Grey and some Vallejo Emerald.
Other metallics will be "as I go" ...

Here is the current list of colors and close enough Vallejo equivalents ...
Again, not going for screen accurate and the colors here are just representative.

Main Hull:
Pale Green - Vallejo 71.095

Stunning work to date!

Personally, I would ignore the model's paint guide and go with the one (I'm guessing you?) posted at SSM.  I see no need for the tren zinc chromate plates.  The sac bomber plates on the belly should be your light ghost gray; and the neck, that perdy emerald green :)

Also, I wouldn't extend the light gray quite so far forward on the starboard side of the bridge "bulb." This image captures that area's look nicely:

Hey Everyone,

Been a while since an update, and not much actual build progress to report. I've been reading up on Vallejo paints a bit more and doing some test spraying.
I've also been fiddling with the color scheme a bit more and testing my circuit board(s).

I've also been experimenting with a DIY wet palette since I'll be brushing some of the detail colors with Model Color.

Another time sink is that I now have (limited) access to a Silhouette Cameo 3 cutter and I am trying to figure out if
it's worth trying to make my own vinyl paint masks.

So, it'll be a few days before I get back to it ...

Cheers,
Spencer

No, there's nothing wrong with your monitor, there are two sets of disruptors there.

User MiniMadnessR53 asked if I could rebuild his set (the black ones), and I think they turned out quite nice.
But, unfortunately, for the sake of my fingers and wanting to get back to my build, it'll be some
time before I consider doing any of that again ...

Hopefully sometime this week I can get back to the build, and maybe even dust off my dual NX-01's
(I really shouldn't be making that kind of promise though  ::))

Cheers,
Spencer

Some sad news I'm afraid ...

My grandfather has passed away. It was not unexpected I will say, but it was still tough.
It's become my folks (and to some degree my) responsibility to settle all his affairs,
like cleaning/fixing up his house, property, care costs, and many other things. That's taking
up most of our time.

I'll still plan on working on the BOP for the next couple weeks, just on and off, mainly because
I find it's a good time to be with my own thoughts and deflate.

Until then,
Spencer

Sorry to hear of your loss Spencer. One of the advantages of this hobby is it allows some 'alone' time to decompress and get away from real life for a bit. Unexpected or not, it is a life changing experience and needs time to be processed. Take care and do what's needed.

Post by: Spencer on April 10, 2018, 10:08:03 am
Thanks for the kind words everyone.

I'm back and will hopefully be starting work on the BOP this weekend.



I bought a couple DC-DC buck converters that I might use instead of my linear regulator board. It will depend
on how much current the model ends up drawing. Regardless of which, the board will go into the base.

Buck converter above, my regulator board below ...
(https://farm1.staticflickr.com/877/26495682957_223acce9ff_c.jpg) (https://flic.kr/p/GnkirX)

I still have to drill out the rest of the window ports and running lights, then I'll probably go ahead and put a primer coat
on everything.

Rather than try to cut vinyl masks on this build, I'll just use Tamiya tape and a sharp hobby blade to make masks for the
accent panels.

Hi Steve, if you go to the very first post on a thread and change its title, it will update on the forum list (but all previous posts themselves will keep their original titles ...).

I designed the linear board myself, in a similar vein to one I designed for breadboard use (below).

Here's my first attempt at cutting vinyl.

Like I said earlier, I won't be using it for masking on the BOP (too intricate for me right now), but
it does give me some ideas for the base ...

P.S. for those interested, I'm using a Silhouette Cameo 3 and their brand of Matte Vinyl, though I plan on buying some of this:

It's my friend's cutter, but I can use it so long as I buy the vinyl.

Thanks Steve. The cutter is actually my friend's fiancee's, but we're neighbors and so we
share/borrow things from time to time.

It can supposedly cut thin sheet styrene and decal film too.
If it keeps cutting vinyl this well, I'll probably buy one when I save up some cash.




I was going to work on the BOP this past weekend, but the weather was too darn nice to not
be outside ... but I'll be back to building soon ... good priming weather!

Hi everyone,

Sorry for the lack or posts/progress. I sprained two of my right fingers pretty bad a couple weeks ago and they're
still a bit stiff, but I've been itching to get back to work on the BOP.


In the meantime. I've been thinking about the base. Right now, it'll be a simple hollow wooden one,
probably with a darker stain.

Two "angel eye" push buttons will control power to the model (yellow) and weapons firing (red).
In the back will be a lighted rocker switch to indicate power to the base and a DC jack for 9V.

(https://farm1.staticflickr.com/824/27278783917_acea6100de_c.jpg) (https://flic.kr/p/HywU5D)

I'm not sure yet whether to cut vinyl to simply lay the Klingon emblem onto the base under the support rod, or use it
as a template to paint it on. Either way, it will be black!

Cheers,
Spencer


P.S. Here's hoping SmugMug treats me (us) better than Photobucket ...

Spencer, while I am just getting my toes wet in programming in this language, I know enough about OOB to know this took alot of thinking. I also know that plagiarism only counts in an Academic setting! :) Still, I admire the work and thinking!

It looks like you are using a ATtiny85 module. Why this one over, say, a WeMos mini? Just curious as I am shopping around.

Thanks for taking the time to answer! I enjoy your builds!

Hi Steve,

If I recall, WEMOS works at 3.3V right? 5V used by the ATtiny85 is a bit more convenient for me. Plus,
I'm a believer in not having more I/O pins lying around than what's needed.

It's also an exercise in designing my own boards should I ever need to some day, otherwise I would have gone with something like this:
https://www.adafruit.com/product/1501



I'll keep updating github as things progress. Hopefully by the end of the week I'll be limber enough to get back to the BOP.

Hi everyone, sorry about the lack of updates yet again ...

It's taken a bit longer for my fingers to limber up, but we're in pretty good shape now.
And I've been busy with work and summertime stuff.



Right now, I'm debating on primer color. I'm using Pale Green for the base color, and I've found that black primer
as an undercoat makes the green pop much more than using a gray primer. I was planning on doing some pre-shading,
but black primer would sort of defeat the purpose.

I'm thinking about spraying a darker green in the nooks and crannies and then pale green over that. Either that or just emphasizing
the raised details a bit more. Decisions, decisions ...

Spencer
