Nice Find al though he didn't stretch the plane
Over the weekend, I worked out the circuit for the board that will sit inside the Bus and have the 5 LED's needed to light:
Cockpit
Red/Green Nav lights
landing lights
strobe
**Disclaimer** I'm a total beginner at this. Electrical engineering isn't something I was into ever... That was my father's thing... Just had a bunch of Radio Shack engineer books and the internets to help me. If any of you electrical engineers out there see something off with what I'm doin, let me know...
For some reason I went nuts with 555 chips. I used 3... 2 on the main board and 1 for the on/off switch.
I started by working out the strobe effect for the bright white LED. The circuit is actually a modified version of the Flashing circuit found here. By adding 2 10k pots I was able to get the on/of cycle looking just right. I also added a resistor plus a diode in reverse to give me that strobe pop... otherwise it's just a blinking circuit.
Then I made the LED dimmer circuit. Only difference from the dimmer found here, is my addition of a 100k pot (didn't have a 50k). This should help me fine tune the green hue in the cockpit so it's not as bright as the nav lights. This may be overkill, but I think watching every episode of SHIELD several times over has done something to me...
Only part of the main board that doesn't use 555 chips are the 3 remaining LEDS for the nav/landing lights... and not because I didn't try to somehow incorporate another chip in there.
So here are the boards... Top breadboard is the ON switch and bottom board is for the main lighting.
Lights on.. managed to get a shot just as the strobe was lighting up... all 5 leds!! :cool
What's the copper plate you ask? My on switch...
This I'm blaming entirely on SHIELD and their spy stuff...
I've rigged this all up to turn on at the touch of a finger. The copper plate is just for testing, but the final version (shield logo) that will be on the base will be the on button. The idea is when the logo is touched on the base, the logo lights up with that blue hue and the Bus comes to life.. all lights inside and outside come on.
The capacitors you see on the top board are just 2000mf.. about 20 seconds worth of lights... just enough for a video...

So now I have to take all that and make it look pretty on a PCB and (at least for the Main board) make it fit inside the Bus.
**EDIT: If anyone wants to play around with the schematics and/or files for the PCB's when I'm done, shoot me a PM. Since it can be modified for different applications (with at least an internal available width of 35mm; for the board being built into the Bus), ON/OFF times, ON sensitivity, number of strobes and frequencies... The chips make them pretty versatile. Later on, I'm going to modify the strobe circuit to have standard strobes for a Zvezda 747-8 that I still have in the box. Fun times...

some trial and error but I'm quite happy with my first in-house PCB. Unfortunately, the board pictured is now in the trash. Drill bit broke on the 3rd hole I was drilling.:angry
So all work stops for the next few hours while I lug my keister down to the center of Athens to pick up some carbide micro-drills and a drill press attachment for my dremel. :facepalm My cnc laser can't come fast enough...
anyway... here it is... the SHIELD AMCS CXD-23 LED board...

Sweet thats cool looking Will a shame to put it where no-one Will see itsome trial and error but I'm quite happy with my first in-house PCB. Unfortunately, the board pictured is now in the trash. Drill bit broke on the 3rd hole I was drilling.:angry

Thanks... The addition of the SHIELD logo is part of the "story" behind the model. The way it's dancing around in my head is like this: Since Coulson has a Bus on his desk, it's more than likely to have been made by SHIELD... and since it was made by them, it should have their logo.
If my electrical engineering skills weren't nooberish, I probably would have gone with my idea of incorporating the logo as part of the traces in the circuit layout...

Here's the new, revised LED board... all drilled out... I used the laser printed design on glossy photo paper heat transfer method to get the mask for the etching. Used Sodium persulfate in a glass jar in a double boiler on a hot plate to etch the board.
All put together... one resistor was damaged and was replaced after I noticed it in the pics.
Each base around the LED was pained with several coats of model master semi-gloss black to block out the LED light. LED's were also flattened to allow for easier drilling.
then sleeved with 6.3mm styrene tube THEN black insulating wire wrap was put around that to block out the light completely. The tubes were made a bit taller than the flattened LED's to act as a cup for the epoxy once the fiber optics are in.
And here it is all lit up. I adjusted the strobe to be on long enough for the pic and the forward Green LED hasn't been dimmed.
The whole board is going to get conformal coating to protect everything before I put it inside and start closing up the Bus...
So that's my very first, completely in-house PCB I engineered and manufactured. I like it.
I'm going to be making a few of these boards (without the SHIELD stuff) for some other models I have that I now have the itch to light up...

Here's an update to my build... Contest is over, but the Bus isn't done..Yet.
This is a mockup of the 12v power lines into the Bus.
on the model
Cockpit detailing
Just before closing up the cargo area
closed up
Painted the engines
rear section attached so I can run the fiber optics
let there be light!
So that's where she's at now. I have to attach the center section and wings, finish off all fiber optics THEN I can work on the hump for Coulson's office. There's also some detailing and scribing that needs to get done prior to paint.

I love this thing. Not a fan of the show really but love this. Especially love your enthusiasm for the subject!

Man, this is way cool!!
Thanks for the kind words...
I'm no big sci-fi geek or did I read comic books growing up. I was always building things. Only recently did I get involved in this whole replica prop world and the sci-fi stuff.
The enthusiasm I show for this isn't based on the subject, but rather, on my love for what I do. Doesn't matter what I'm working on, same enthusiasm... usually the larger the scale the crazier I go...

Have been working on a revision of my stand pipe is hollow actually was a 4 piece lasercut plates wires from stand to plane Will run through here
Only thing i still Need to cut is a ring wich Will hold the plexi plate
Plane is as close to finish as i would prefer my Prometheus takes up most of the time
