There will no doubt be a flurry of Doom3 themes this year and next, so I thought I'd add my project to the mix. Project Mars City will be fun to build with lots of kitbashing for that military/industrial Doom3 look. Expect lots of armor, mesh, lighted machinery, pressure doors, plumbing, and maybe a few sculpted animatronic beasties.

This case will be a Doom3 gaming MONSTER, DangerDen watercooled, and top of-the-line hardware and components that have yet to be determined. I have an Antec Super Lanboy to use as a base, since it's very lightweight, and the kitbashing/structural enhancements will add enough strength to this otherwise flimsy case.

Since Mashie and I are both working on Doom3 inspired cases, we set up a Live ModCam so anyone interested can see the projects as they progress. Please no complaints if the cameras aren't up 24/7--we are working on getting a dedicated server. Live ModCam (http://www.modcam.net)

I'm making a base unit for that Antec case, with Mars terrain--i.e rocks and craters--it will also house the optical drive. I need to free up the 5.25 drive bays for the video monitor that will be integrated--probably a Xenarc, earthlcd or equivalent.
Video games category is one fo the most popular entertainment sections of the Weekly Ads (https://www.weeklyads2.com/) during holidays. Check Supercheap Auto Catalogue (https://www.catalogueau.com/supercheap-auto/) and Spotlight Catalogue (https://www.catalogueau.com/spotlight/).

Here is the start of the base that will have a Martian terrain look. It will also house the optical drive and a few other goodies :D

I found a motorized 7" LCD screen meant for in-dash applications. The LCD is a Panasonic OEM, so it should be pretty good. Anyone know of other brands I should look into?.

After speaking with a friend today who was kind enough to spend some time and give great ideas, i took some screenshots for inspiration. Mr. Nervous lead me in the direction of a 3/8" hose watercooling setup, so I will go with DangerDen blocks and pump for the system. There will be lots of elements from the game as far as look and feel, plus some imagination thrown in. There are so many directions a mod like this can take, but after speaking with D he thought the case itself would be cool if represented as one of the building installations on Mars, with a few water cooling parts outside the case and then slithering their way inside.

The Antec case at this point is just a shell, having popped most of the rivets and drive cages offm and will hardly be recognized once completed.

Any ideas are welcomed, this should be lots of fun to join in on! :D

The Antec Super Lanboy is pretty flimsy---think soda can. What I did here is took the panel from the motherboard side and swaped it. I then cut a third off from the panel and mounted an aluminum bar on each side--it gave it lots of rigidity. Then I installed two utility hinges. The smaller section will be permanently mounted while the other side opens for accesability. Now I can mount parts to the smaller section (like the res for instance) permanently. This was Dick's idea--and a good one.

The hinges will be hidden eventually with kitbashed and scratch-built model parts.

Here is a shot of the half cone shaped section i completed last recently.

This section with aluminum rails will have a slide out tray with a MediKit box for cookies and snacks ?

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_2-(3).jpg

Martian landscape material. I'll use this sheet as a mold for making resin sections on the base.

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_2-(6).jpg

I got a few various sized rubber rock molds for Martian terrain. These are used to create boulders and rocks for model train landscapes, but in this case will be for Martian terrain :D

I mixed up some bondo and spread it on the mold with a stick like you would frosting. about 90 seconds later I pulled them from the mold:

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_3-(6).jpg

Well after working about 10 hours I just about finished the base. This will be covered in Martian terrain, with a little of it on the case itself to blend in.

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_4-(11).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_4-(3).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_4.jpg

Before I can cover the rest of the base with Mars terrain, I have to get the bottom part of the case finished, so I can blend it in. The case itself will become a structure modeled after the buildings in the game.

http://www.thebestcasescenario.com/projects/doom3/shot00069.jpg

http://www.thebestcasescenario.com/projects/doom3/shot00070.jpg

Here I started to create the scribed panels that will cover the case. On top of this will be various parts from model kits. Lots of pipes and small details as well. I penciled out some lines on the plastic panels, and using a scribing tool I cut the grooves you see here:

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_6-(3).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_6.jpg

the many hours of kitbashing has started--I scrounged some parts from various model kits, but it looks like I'll have to go buy some more at the hobby shop.

Created a window on the building that will give a peek (albeit dusty) view into the interior of the case. The window will be slightly angled off the face of the building, like a bay window. I also added rivets to the scribed panels for even greater detail.

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_8-(1).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_8-(4).jpg

The sound board arrived today--yay! It has a LOT of features Some of them are:

*9-15v power input

*8ohm speaker ready with amplifier. Can also be plugged into PC sound card via mini plug.

*RS-232 Interface for controling 9 channels of sounds via simple ASCII commands from your PC

* 6 channels of audio that can be recorded (4 minutes total) individually, and played simultaneously or one at a time. You can use momentary switches, IR triggers, just about any switch. Sound is recorded on-the-fly from any output source using a 1/8" min plug. There is no soldering at all required with this board.

Will have lots of Doom3 sounds recorded into it for various features on the case, like doors opening. Also plenty of beastly monster sounds and voices. This board is avaialable at Blue Point Engineering (http://www.bpesolutions.com)

http://www.thebestcasescenario.com/projects/doom3/snd_board.jpg

Mashie had a great idea for my airlock door, and kicked it up a notch with a challenge to make it servo operated. When the system powers up, the airlock opens just like in the game (complete with sound effects) to reveal the radiator and allow air inside the case :D

In this pic you see the housing I completed for the door. Next step is to make both doors and rig the mechanics, and of course model the details.

The housing will actually be partway inside the case, just propped up there for the picture.

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_9-(5).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_assemble_9-(7).jpg

Well the structure for the airlock is complete. The only [H]urdle yet to jump with Mashie's challange is to connect the servo mechanism and apply the relay hack to the pcb board that controls them. The servo will be cable operated using a simple scissor type mechanism. The Black Ice 2 Xtreme radiator will be mounted on the back of the airlock, with the 120mm fan inside. Before all this is done I'll decorate the door with all the little details found in the Doom3 screenshot.

Figuring out the right position of the airlock in the case:

http://www.thebestcasescenario.com/projects/doom3/dm_mockup_1.jpg

For the top of the case, I chose to make the same rounded "crown" type moulding you see on the exterior buildings in the game. First I had to frame out the shape by cutting the joists from plastic on the scrollsaw. Next step is to put the "skin" on the joists to create that moulding's shape around the case. I'm thinking of putting another feature on top, maybe the "Communications" tower, with small windows all around it, perhaps an oscilating dish---who knows. What i really want to do is use this space to put a small animatronic creature that busts out of the building: head going side to side and arms reaching out and grabbing...just the head, shoulders and arms--haunted house style :D

http://www.thebestcasescenario.com/projects/doom3/dm_crown-(4).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_crown-(7).jpg

The moulding is now just about complete. The joists were "skinned" and acrylic half-round rod was heat bent and put in place. The next step is to do a little mud job with Bondo to fill the seams and even out the round corners.

http://www.thebestcasescenario.com/projects/doom3/dm_crown2-(9).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_crown2-(3).jpg

small update, but its taking many hours to get just right. The top of the building was smoothed out with Bondo and shaped. After wet sanding a coat of primer was given to see how its shaping up. Working now in the vertical support pieces. Each one is 5 layers of plastic sheetglued together, then carved and shaped.

http://www.thebestcasescenario.com/projects/doom3/dm_crown3-(1).jpg

http://www.thebestcasescenario.com/projects/doom3/dm_crown3-(5).jpg

Crim, I like the bondo job you did but you think that's sturdy? Bondo cracks easily :D

With the framing i did its extremely strong-I took a pic while standing on it--so there is 180lbs right on the bondo parts--mind you I wouldnt do this if I thought 6 hours of work would be even slightly cracked or ruined :p

http://www.thebestcasescenario.com/projects/doom3/built_tough.jpg

Before I can close up the window housing, I needed to add some detail behind the glass, giving another layer of interesting little pipes, machinery and gadgets. I also need to install the lighting effects in this window "box" as well. This stuff is tedious as hell, I cant wait to get onto hardware and water cooling :D

We all make mistakes, and on the first Airlock label I SPELLED HAZARD WRONG with two z's..I've been making that same spelling mistake for 25 years now..pretty funny that i posted it wrong. here it is fixed up:

http://www.thebestcasescenario.com/projects/doom3/door_decal-(5).jpg

http://www.thebestcasescenario.com/projects/doom3/door_decal-(4).jpg

This sad pentagram I made was later replaced by design by cgrant26 and laser etched by DeathLok30040. You can see their efforts below ;)

Created a pattern for an etched pentagram that will live behind the small window on the side. Once I have it etched I'll light it and do a mockup on the case.

The 1/4" plexi piece was first covered in blue masking tape. After that a printout of the pentagram was applied using spray mount adhesive. With an Xacto blade I scored the pattern down to the plexi, and then removed the protective layers. I coat of flat black paint was sprayed on as a guide for etching, then all the paper/masking tape was removed.

http://www.thebestcasescenario.com/projects/doom3/pent_window.jpg

With a carbide bit I started removing the paint and etching the surface. The X-acto blade created a nice channel in the plexi for the bit to follow along in. Once etching is complete, I'll polish the edges of the plexi, mount the window and install lighting.

http://www.thebestcasescenario.com/projects/doom3/pent_etch-(3).jpg

Once the etching was complete, I polished the edges of the plexi in preperation for the 4" CCFL lights. One red, one yellow will light the edges. I'll use the same automotive CCFL's I used for Metropolis (http://www.thebestcasescenario.com/projects/metropolis/metrop_pics/gallery/metrop_final4.html) . They are really bright and the colors are true.

Here is the etching in the window box you've seen before. There are two panes of glass, one in front and one behind, with the etching:

here is a cheesy photochop enhancment:

Amazingly great window etch-

http://www.thebestcasescenario.com/projects/doom3/IMG_8351.jpg

Since the airlock is not just for show, a lot of thought had to go into mounting it. I decided to build the airlock and Black Ice Extreme 2 120mm radiator into a unit that could be removed easily, hence the thumb screws. The unit also had to be pretty solid to keep the airlock doors in good alignment.

btw before anyone asks (like a certain other modder) the interior will be painted to match elements in the game :p

I was going to have a Chainsaw fangrill cut from aluminum--however I was persuaded to make a reproduction from the game. I will use this gunsight grill as a base (with crosshairs removed) for it. The grill will be on the 120mm fan inside the airlock, which will be lit with several LED's. I might make a silicon mold of this grill when complete, so I can reproduce them and sell 'em. :D

I will model the chainsaw in plastic sheets to create layers until it is built up. Then I'll carve and shape. Here you see just the motor and handle assembly

http://www.thebestcasescenario.com/projects/doom3/chainsaw_grill-(1).jpg

http://www.thebestcasescenario.com/projects/doom3/chainsaw_grill-(5).jpg

Layer by layer, the chainsaw takes shape. and Yes..it will have a bloody blade :p ;)

http://www.thebestcasescenario.com/projects/doom3/chainsaw_grill2-(7).jpg

Got this part done, all is needed is the second handle, saftey brake, pull start handle and saw blade :D

A little blade action:

The chainsaw WONT be mounted on the ring in that drastic of an angle--it doesnt look right. it will be mounted at about 15 degree angle at the center.

It's time to get the rest of the base covered in Martian terrain--but before I can do that, I have to create the stealthed-out bezel for the optical drive that is on the front of the base.

On the bezel will be none other than the Doom3 logo, faithfully recreated in styrene sheet plastic, painted and airbrushed complete with metal plating like the original. the logo will be "pillow embosed" into the Martian surface, and when the optical drive button is pressed it will travel with the tray.

here is the front of the case where the logo is going:

http://www.thebestcasescenario.com/projects/doom3/logo_area.jpg

here is the logo, as if we all don't know it by now
http://www.thebestcasescenario.com/projects/doom3/doom3_logo.jpg

A few of you have requested a "how to" for the logo I made--here it is :cool:

The first step was to print out a Doom3 logo to the scale I wanted for the case mod. Next I carefully cut the letters out one at a time with a very sharp X-Acto bladeto use as a template.

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto2-(2).jpg

The paper template was then mounted to thin styrene plastic sheet using spray mount adhesive:

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(1).jpg

The plastic was then carefully cut along the template:

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(2).jpg

The paper template was then removed:

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(5).jpg

Next I used a mechanical pencil to draw in the signature Doom3 metal plating:

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(6).jpg

With a scoring tool, I then lightly scored the plastic along the pencil lines:

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(10).jpg

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(12).jpg

To build up the sides of the letter, I cut strips of plastic, cut them to size one at a time and glued them to the letter. I use Flash brand super glue, and a "kicker" or accelerator that makes the super glue dry instantly when sprayed on.

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(21).jpg

The letter was lightly sanded and then given a few coats of laquer based, micro-filling primer made by Alclad.

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(26).jpg

here you have the primed letter, ready to mount and airbrush ;) Lastly, I'll do the "3" and finish this all up.

http://www.thebestcasescenario.com/projects/doom3/how_tos/doom_letters/letters_howto1-(29).jpg

I got around to casting some rocks for the Martian landscape--then applied a little basecoat of paint. From images of Mars, looks to me like plenty of rusted soil and blackish/gray rocks poking out. Here I imagined bedrock, what the building would have been built on-...sort of an outcrop of blasted and machine cut stone. The sides of the base will be smoother terrain. You can also see the Doom3 logo, which is now part the optical drive bezel. I'll have small spotlights illuminating the bottom half of the logo eventually

I got around to shimming up the door, aligning it and so forth--I mounted the bezel on an old CDROm just to test it and rigged up a button. here is a 5second video:

As you can see..I'll have to build a housing of some sort to mount the parts in. Parts include 6.5" LCD, Resistive Touch Screen Panel, inverter for the two backlights, controller card and cables.

This LCD will be mounted in the 5.25" bay area above the airlock, possibly behind a door that has the UAC logo emblazoned on it. This LCD will run off of a secondary graphics card and have an gui to launch apps, videos and scenes from the game, or monitor the webcam that will be part of the mod...I guess there's lots of fun stuff to use it for!

Now that the base unit will house the two hard disks and CDROM, I needed to get power into it. I made a distribution block that has two male Molex connectors and four 3-pin fan connectors. The fan connectors are for the two 60mm fans that will be in the base, as well as for lighting the Doom3 logo on the CD bezel.

The block is made from aluminum stock and a cut piece of extruded aluminum door threshold, then painted with DupliColr red annodized-look paint. No one will ever see this power block, but I still like to finish "what isnt seen" ;) Once it's dry and assembled I'll post pics:

http://www.thebestcasescenario.com/projects/doom3/power_block2_3.jpg

http://www.thebestcasescenario.com/projects/doom3/power_block2_4.jpg

This should help clear a few things up :D

The base unit will now house the CDROM, as well as the two hard disk drives. The drives are on a removable frame that locks in place once it is slid into the base. I also made a fan frame to hold the two 60mm intake fans. Ports on the bottom odf the base will vent the air.

http://www.thebestcasescenario.com/projects/doom3/base_unit_1-(3).jpg

http://www.thebestcasescenario.com/projects/doom3/base_unit_1-(4).jpg

Here you can see the simple locking mechanism for the HDD frame. The frame slides on this, locks into place under the lip and is secured on the opposite end by two screws.

http://www.thebestcasescenario.com/projects/doom3/base_unit_1-(6).jpg

http://www.thebestcasescenario.com/projects/doom3/base_unit_1.jpg

In the first pic you see the base unit and the new top that the case will sit on. The top is 0.40 styrene reinforced with fiberglass cloth and resin. The oval shaped opening on the side is the intake for the HDD cooling fans, and will have a special grill made for it eventually.

http://www.thebestcasescenario.com/projects/doom3/d3_base_terrain-(13).jpg

In this pic, I'm in the process of adding more Mars terrain made from rubber mold castings and applying it to the side. It's really time consuming task to get it looking natural. You can see that the rock has a horizontal grain, to look like cut bedrock. Once all the rocks and stones are carved and glued in place, I go back and blend them all in. Then a few hours work with a Dremel and carbide bit to add small carved detail.

http://www.thebestcasescenario.com/projects/doom3/d3_base_terrain-(23).jpg

And here are the main parts in place:

I decided to put a plate steel walkway around 3 sides of the building, and Mashie (http://www.mashie.org) thought it a good idea to raise it up from the terrain. I'll mount the walkway now on aluminum columns planted in the ground, level with the airlock. Will have some ammo here and there on the walkway as well. This detail should look really cool when done ;)

well i FINALLY finished the terrain--I'll take pics when its prime painted. Meanwhile I hooked up a single red Lazer LED to that killer window and snapped a few shots---I'll adjust the color to more orange by adding a yellow Lazer unit and a second red:

The terraforming operations are basically complete on the base.My next step is to integrate 2 rocks with hidden LEDs to light up the lower half of the Doom3 logo with amber light.

http://www.thebestcasescenario.com/projects/doom3/terrain_complete-(4).jpg

The white oval section you see is a rough opening for the HDD fan vent. It will not be oval once the grill is modeled into it. I'm thinking two fat vent pipes that go up the side of the building.

I decided to make two miniature spotlights that will be mounted on the base to illuminate the Doom 3 logo. These little babies will be mounted in the rocky area on either side of the logo and pointed towards the lower half. Completely adjustable as well =)

http://www.thebestcasescenario.com/projects/doom3/spotlight_1-(4).jpg

Here is a spotlight broken down:

Its made from an aluminum tire valve cap, a piece of aluminum U channel, steel rod, rubber grommet, aluminum tubing various screws and a 2-pin fan connector as a socket for the LED.

I think with a little tweaking this lighting for the logo will be really sweet. Here are a couple early pics, remember that nothing is painted yet:

Some of you have been waiting to see how the touch screen LCD from www.earthlcd.com will be mounted--well here it is!--I started constructing the architectural piece that will house the LCD unit---complete with motorized blast/storm door.

Here is the part during framing. You can see the curved channels that the blast door will ride on when the button is pressed:

The housing for the LCD touch screen is now more of a module--removable from the case with just a few screws. Much better than mounting the various parts of the LCD inside the case where you cant get to them---we all like easy access to the inside of the case for tweaking and fixing what isnt broke right ? :D

Here is the unit, I'll explain pic-by-pic. This first shot is were i left it for the night, having created the various mounting plates, brackets and what-not to hold the screens in place. The control panel for the LCD was just a pcb with a single LED and 5 little tactile buttons (power, menu, navigation etc). The buttons wont be visible on the mod, but hidden behimd a panel:

You can see here the small clear acrylic hemispheres I glued onto the microswitches.

http://www.thebestcasescenario.com/projects/doom3/LCD_1-(7).jpg

Inside the unit, the housing will hold all the LCD parts (see below) as well as the servo and electronics for operating the blast door.:

WHEW!! Ok all the basic engineering and construction on the LCD module/motorized blast door is finally complete. I've completed the roll up door and integrated all the parts of the LCD kit. The next step is to finish up the airbrushing/hand painting and mount the servo unit to operate the blast door.

here is the roll up blast door. It was constructed in segments, with each segment having its own bolt-type hinge, so its very flexible. The bolts are small steel rod inside plastic tubing, with a hing plate. there are 24 hinges in all. Each hinge can fit inside of a dime--so its pretty small. It operates similar to a store-front security gate:

http://www.thebestcasescenario.com/projects/doom3/lcd_module_finishing-(12).jpg

Here you can see how flexible it is. Each segment had to be slightly smaller than the radius of the blast door tracks that it rides on.:

http://www.thebestcasescenario.com/projects/doom3/lcd_module_finishing-(15).jpg

The door is inserted from the bottom of the track:

http://www.thebestcasescenario.com/projects/doom3/lcd_module_finishing-temp.jpg

Here is the door in place. It still needs fine tuning and adjustment, but that will happen when the servo is installed:

Once the parts of the LCD kit are mounted in place, you will get a sense of the how this design works from a structural standpoint:

The section that holds the control panel for the LCD now has a hinged door to hide it:

Here i'm adding a detail strip to the top of the module. Details were scribed and cut from plastic and then mounted to the strip (in white) The strip is then glued to the top of the module. Creating a detail strip firt makes it easier to add small detail, rather than gluing them directly to the larger module itself. Also if ya screw up, you wont have to scrap glue off of a finished part :

http://www.thebestcasescenario.com/projects/doom3/lcd_test_2-(10).jpg

What may not seem like a big update on this project actually took a tremendous ammount of work on my part--in between dealing with other projects/clients I managed to create the final piece that finishes off the front of the case--the molding above and around the airlock door. The design is pulled from the game with a few added touches to make it blend in with the LCD module that lives above it.

This scratchbuilt part had to fit nice and snug with the airlock while allowing it to open smoothly, so many hours of measuring and cutting the styrene sheets was needed to get a tight seam. The decorative panels that were laminated onto it made it so strong that when knocked on it sounds like knuckles on a football helmet--yeesh..very strong indeed.

Once this section is airbrushed and blended in with the rest of the front, it will start to come together. I'll put all the parts together tomorrow and post a pic of the entire case. You'll also notice that i started painting the Martian terrain. I'm waiting on a few bottles of paint before i add the final touches by hand and airbrush.

meanwhile, i completed the platform and all that's left to do is fill some tiny seams and paint it to match my theme. I took a lot of elements from the game such as tread plate, square tubing handrails, a set of stairs on the right side and a small circular landing on the left.

Took a break from video production tonigfht and started painting the platform. First a heavy coat of flat black was airbrushed on to fill in all the deep nooks and crannies. next I started adding some layered texture outlines beginning with dark burnt umber. Then came a gunmetal color followed by dark brown. Highlights were then added with a color called "jet exhaust" (for military models obviously) and after that some rust was sprayed on. A well tuned and maintained airbrush is important for this kind of work...so keep those tools clean! :D

All these colors form a base coat that becomes very subtle when the hand painting and color washing begins. It all adds to the depth of scale and color that is needed with mostly metalic architecture. I'll be sure to show the progression of hand painting very soon.

Here are a few pics of the scratchbuilt Steam Generator I'm working on at the moment--

The 12v smoke unit has a small fan built in that forces the smoke out of the stack. Well thats not enough for me, so when I build the portion of the feature that connects to the end of the brass pipe, (see below) I'll install a 40mm fan inside to really give the illusion of pressure. Another fan also adds to the volume of smoke that is generated from the unit. This feature at the end of the brass pipe will be a housing of some sort that will have a mesh screen (for letting the steam out, of course!) and red lights inside--I think it will look very Doomish :D

I still have several hours to work on this, kitbashing and scratchbuilding to integrate the whole thing into the side of the case.

http://www.thebestcasescenario.com/projects/doom3/steam_unit-(1).jpg

That vent with the mesh on it allows air in for the smoker unit:

http://www.thebestcasescenario.com/projects/doom3/steam_unit-(3).jpg

http://www.thebestcasescenario.com/projects/doom3/steam_unit-(6).jpg

In this pic you can see the smoker unit:

http://www.thebestcasescenario.com/projects/doom3/steam_unit-(11).jpg

Here are some pics to give you an idea of how the side panel with the steam unit will look. This scratchbuilt structure was inspired by several screen shots of Mars City building exteriors.

The large main pipe was built as a whole then cut into two sections. You can see here the ribs that form the shape before it is skinned.:

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(24).jpg

For the round top of the pipe, I formed it into sections and then filled it with Bondo to create the shape:

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(30).jpg

In this pic you can see the smoke oil fill-tube poking out of the pipe. This fill port will have a removable wheel valve on it eventually, just to mask it.

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(32).jpg

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(35).jpg

This vented area is where the "steam" comes out of. With the red LED's in there, it will be pretty slick:

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(37).jpg

http://www.thebestcasescenario.com/projects/doom3/steam_unit_two-(44).jpg

I havent had much time to work on the Doom3 case because of commitments to client projects , but I have some previously unreleased pics that i will post in the next few days. ;)

Here is a couple shots of two power distribution boxes I made. These will be painted to match the interior of the case theme basicaly.

http://www.thebestcasescenario.com/projects/doom3/disto_boxes-(2).jpg

http://www.thebestcasescenario.com/projects/doom3/disto_boxes-(1).jpg

For this one, I made the front plate of the project box out of clear plexi. I then created a simple graphic in PhotoShop and printed it on a transparency. I then epoxied the graphic on the Plexiglas lid and gave the whole thing about 6 coats of clear acrylic spray paint. Two super bright (7000MCD) LED's were hooked up in parallel for interior lighting. You won't be able to actually see this lighted box unless the case is opened, but i wanted to have a little fun making it.:

Here I placed it in the case just to get a little darkness for the photo:

It's becoming obvious that the single 120mm rad was not going to be enough cooling for the AMD FX55 and twin 6800 Ultras that will be used for this project--My roof section has now become a cooling tower. The Black Ice XtremeII Radiator should be a better solution for cooling--I may even look into Danger Den's heater core. The PSU will have to be pushed back and outside the case a few inches, but I'll make sure to do some model building and make it blend right back into the case.

I appreciate everyone being patient while I take care of some other projects---I've been itching to get some work done on D3 myself!

Well here is the latest update...While the airlock was cool...i was pretty much "meh" about the LCD control panel--and I think a few of you out there were as well..so I went and carved out that LCD panel area and installed a tiny light box--with an LED. I then went and made an inkjet transparaency of the airlock LCD from a screen grab--I also enhanced the image with some saturation (since it's the size of a postage stamp!) and sharpening.

I then used a little spray adhesive to mount this inject transparency (there were like 6 images on the sheet in case I screwed up cutting them out) onto a sheet of white paper. After cutting it out, I mounted it on that little plastic light box I made and coated it in 5minute epoxy to create a lens.Here's some pics:

You can get decent color fades with rattle cans. Armed with Krylon Fusion paint (which comes in limited but very "Doomish" colors like Burgundy, hot Pepper and black) I gave this Logitech MX1000 laser mouse a simple, easy paint job that I think looks pretty neat. The tail end of the mouse is black, then fades into the burgundy and then into the hot pepper color in front. Once the clear acrylic topcoat is cured, i'll give it a light wetsanding and then some 3M compound and finaly a polishing glaze.

You can work the spray paint on any piece to create a fade, as long as you don't put it on too heavy or work too close to the object. It takes practice, but if you don't have access to an airbrush you should give it a try!|

Adding just the right amount of detail is really important when scratchbuilding and kitbashing on a project like this. It's easy to add too much detail, creating a confusing pallet of shapes that simply adds confusion to the overall look. Picking the right parts for kitbashing comes from lots of trial, error and experience, and literally hundreds of rejected parts and configurations pile up before I commit to gluing them on. Even then I may rip pieces off if it doesn't seem to fit later on as the work progresses.

Tamiya models are among the very best kits you can buy. The detail is amazing, and the quality of their molds are unsurpassed for producing clean, crisp injection molded parts. Although pricey, these kits have been used for kitbashing by master model makers for years--even back to the first Star Wars. If you come across any production shots of the ILM (Industrial Light & Magic)model shop, you'll be sure to find dozens of boxes of Tamiya military kits in the background.

I finally found a solution to making the blast doors and airlock open--make linear actuators from old cdrom drives! RC Servos just dont have enough travel in the arms to open the doors I made properly, so by taking the high torque gears and motor that open and close the tray to a CDROM, voila, a linear actuator. I have a short video showing how it works, I'll get it up asap.

Here is a shot of the motor assembly disassembled that will be mounted to that tambour style blast door that covers the LCD on the front of the case:

http://www.thebestcasescenario.com/projects/doom3/linear_actuatotor-(1).jpg

This pancake motor is perfect because it is of course, 3-5VDC reversable. It's also designed to last a long time:

http://www.thebestcasescenario.com/projects/doom3/linear_actuatotor-(2).jpg

Here is the track assembly. The plastic geared "track" was taken from the CDROM tray and mounted on my aluminum rail:

http://www.thebestcasescenario.com/projects/doom3/linear_actuatotor-(14).jpg

The slide assembly has a built-in spring (inside the round alum tube) to prevent the motor from sliding off the geared track when it reaches the ends of the travel. The springs also make sure that the main motor gear is always in contact with the first tooth of the geared track, and ready to move in the opposite direction:

Mechanical airlock? OK!

This nice little challenge is finally complete from a mechanical standpoint. The motors from a CDROM would not be powerful enough to open and close these airlock doors, so the logical replacement would be to use hobby servos. For those of you familliar with these high torque gear boxes, you know some of them pack serious strength--

What I did was create another linear actuator to open and close the doors. Unfortunately the standard servo arms only rotate 45 degrees, and this would not give me enough linear "travel" along the gear bar to open and close my airlock doors. Hmmm..

Solution was to use these specialized servo motors called "retract servos"--these are used to raise and lower the landing gears on flying model aircraft. Not only do they rotate 170 degrees, they also have a higher torque rating than standard servos--perfect for what I need.

You can see I created a "scissor" type mechanism to open and close the airlock doors--sometimes the most elegant solutions are the most basic in design--I had to be extremely accurate with measuring/cutting/drilling in creating this mechanism, and it took some serious tuning to get it running like buttah. The entire mechanism is very robust, so it should last for years without needing adjustments.

I'll have a video up ASAP showing the doors in action

Enough gab, on with some pics:

You can see that i also made the cut-out for the 120mm Panaflo fan--Airlock opens, fresh air comes in--Here is the airlock module bolted onto the case. I'll be making a housing to cover the scissor mechanism, as well as all the wires for the servo and lighting:

http://www.thebestcasescenario.com/projects/doom3/airlock_mech-(12).jpg

Here is the mechanism, top view. All painted and plastic parts (and gears) are lubricated with Lithium grease, as anything petroleum based would eat the plastic:

http://www.thebestcasescenario.com/projects/doom3/airlock_mech-(1).jpg

Here you can see the Hitec HS-75BB Retract Servo, and b\gear bar i took from a CDROM tray. The gear on the servo is also taken from the CDROM motor, then it was mounted with tiny screws onto a standard servo wheel:

http://www.thebestcasescenario.com/projects/doom3/airlock_mech-(5).jpg

Inside the airlock, I did some kitbashing and scratchbuilding to add details to the back of the doors--Inside will be a light fixture (red LED) as well, pics for that coming up soon:

Here are a couple pics I took a few weeks ago during painting and final assembly:

The power block simply makes putting this complex mod together much easier. It gives me a break point in the power line so the case itself can be removed from the rocky base that holds the SATA CDROM and harddisk..

These dual 60mm fans help cool off the Fujitsu 15kRPM drive.

I decided to do away with many of the mechanical switches and buttons on the mod and go for solid state with an IR remote control--because how cool is RC??-- :D I picked up a 12 Channel IR Relay Board (http://www.electronics123.com/s.nl/sc.8/category.36/it.A/id.376/.f) (in kit form) and assembled it in about 2 hours. The nice thing about this board is that you can have an on/off configuration on the channels or momentary switching, or a combination of both. To test it out I hooked it up to the blast door module--works like a charm.

Here is the air intake vent for the HDD cooling fans. This scratchbuilt piece uses some styrene sheet, modder's mesh and two copper plumbing elbows. To get the subtle shading in the paint, first it was airbrushed, then hand detailed and finaly a soft shading with Doc Browns' weathering powders applied with a sable brush. This is pretty much how I painted the entire mod.

Whew!...alright it looks like its finally in the home stretch--Nothing more to build, just paint and assemble--easier said than done--although since the entire mod is built around modules, everything should fit right into place. Lots of wiring to do as well--but its 99% done overall. Here are some pics from last weeks build:

Etched pentagram window in its frame with LED lighting. Basically its 6 ultrabright red lamps wired in parallel:

Here is the roof module during painting. The cover caps off the roof nicely and includes 2x 120mm fan vents for the Black Ice pro radiator.

Here you can see that i curved the interior of the roof module to allow for airflow off the radiator:

The Antec case is really small for a mid-tower, so I built an extension for the rear of the case. This allows me to push the PC Power & Cooling 510 SLi PSU out the back about two inches, giving me preciuous room inside for wire managment and components. The round holes on the extension piece are for PSU fan exhaust, an 80mm fan and a hole for the water pump. This estension piece also conceals all the typical messy wires on the back of the PC :

There is even a hinged door for access to the I/O panel of the motherboard.

Once its all painted up and weathered, I'll take individual pics of all the components before assembly to show all the parts.
