Re: my update and some good news for bulb buyers
One hopes that's just an oversight, which will be rectified.
Hmmm... I haven't yet received a tracking number to indicate that they've shipped.monz said:

DIY in Winnipeg
Seems like most of you guys are in the west coast or Toronto. Any Winnipegers hanging around?
I've sourced out pricing for my lighting from a local supplier, Lightmore, and was able to get a discount from work. I can get a 400w MH for $21, ballast for $62 and the mogul socket for $5. Not. Sure beats buying from lumenlab, et all.
I've seen some lenses for old CRT projectors. Has anyone tried those? They are large diameter, so they should allow tons of light through and would be of good quality.
Staples had a benq 531 15" monitor on sale last week for $199. Has anyone used these? Specs look good, 1024x768, 400:1, 25ms.

Lights, Camera... Lights?
Well, I figured that this would be a no-brainer, people seemed to be able to get stuff from Home Depot, but I can't find any (expletive deleted) lights!
Home Depot / Rona says that they have bulbs (Or they will, whenever they get around to ordering them. There are none on the shelves.) No ballasts or sockets.
Typical reaction at a lighting store can be summarized as a blank stare. "Metal What?"
I haven't tried anywhere that specialises in hydroponics, yet. That's an idea for tomorrow...
I haven't even got to reflectors yet, but I think that may be another whole issue, there. I'm almost considering buying some sheet aluminium and breaking out my autobody hammer and dolly... Presuming that I can find a reasonable source for sheet aluminium. 🙂 The only thing stopping me from doing that is the prospect of final smoothing and polishing... I wonder how much abuse my dremel will take before it fries...
I'm breaking the projector project into steps. The lenses are on the way, I'm negotiating the LCD...
Step 1. Lights. Obviously this begins with bulb, ballast and socket. I'm going to fabricate an enclosure for the whole thing in aluminium for heat blocking and sinking (Bonded fins will be in the air path right before the fan exhaust)
Step 2. Camera. Building the general enclosure and fitting the fresnel lenses, light box and projection lens (with focus box.) I intend to use a mock-up of the LCD (Lucite with a pattern painted onto it to test focus) during this stage to avoid damage to the LCD. Temperature monitoring will be done at this stage to ensure that the LCD can survive the rest of the unit. I also intend to minimise light leaks at this point.
Step 3. Action. Replace the mock-up with the real LCD, and spend a weekend turning into a vidiot. I'm thinking that the extended edition of Return of the King will make a nice shake-down of the project.

heat shielding
I'm planning on using a 400w mhi. How effective is the uv coated lucite in blocking uv rays? What about IR? What considerations (cheap, this is DIY) have been taken on blocking the IR rays?

lens
Hi all
I was wondering if I took a dead camcorder of mine and canabilized the lenc if it would work for my projector (basiclly using in reverse). If it would that would give me a lens🙂

light
was outin walmart looking around and came across a light that i was wondering if anyone has tried, a 12volt, 50watt 2000 lumen hologen bulb. They are about $10 for two of them. Do you guys think this could be a bases of a light engine?
Its one of the type that plugs into the hologen track lights where each light unit has its own power converter.. These bulbs come with their own reflector
looks sorta like this one, but as i said 50w and 2000 lumen, go to homedepot.com and search for this # 320394. was trying to find a pick tp post but computer and i dont see i2i

dont think its bright enough..you loose a lot of lumen after going through the lcd...might work for a small 2.5" lcd
Halogen
Yup, it's likely not going to be bright enough unless your viewing room is pitch black, plus halogen generates WAY more heat per watt than metal halide. Inefficient light production, and requires lots of cooling.
The colour of halogens is pretty harsh, too - you really want something in the 4,000 to 5,000 Kelvin range (most people say 4,200K is about perfect...).

Argylle's camcorder idea
Hey Argylle, better yet, I've been wondering if you could take an old LCD projector, rip out the old/expensive/low-lumen light kit, and replace it with a nice bright Metal Halide bulb.
You can get really nice projectors on eBay for almost nothing because they're older units and nobody wants to pay $700 to $800 for the factory-replacement bulbs for 'em. So what about tearing the back off and rigging your own MH light behind the projector's existing optics/LCD setup?
That way you use all the original high-quality optics and the projector's efficient/high quality LCD system (which will usually have REALLY good reaction time and a great contrast ratio compared to any full-size LCD panel), and all you'd have to do is put in a cheaper light, maybe an extra fan and condensor lens, and a sheet of IR glass/sheet of lexan (anti-UV).
Any thoughts? Anyone try building a do-it-yourself projector ... out of an old projector?

Couple of things...
1. Lamp power. This may or may not be a problem, but certainly the old projector isn't going to provide power to a compatable ballast.
2. Lamp failure detection. Most of these things had all kinds of funny sensors to determine if the bulb needed replacement. You'll have to reverse-engineer the system to deal with the new lights.
3. Size. I was looking at my 400W metal-halide light, and it's more than 1/2 the overall size of the small projectors that I've looked at. This could make it exceptionally difficult to get the light source acceptably close to the LCD(s)
Cooling is probably not an issue, as my most recent reading seems to indicate that metal halide is one of the most efficient methods of producing light of acceptable "whiteness" for projection. This means that watt for watt, the metal halide light will run cooler. (Of course if you're replacing a 175W projector bulb with a 400W metal halide, all bets are off.)
Light leak blocking will be an issue. Mostly because of point 3. Sheer size.
Otherwise, it seems like a good plan. Personally, I think I'd rather take the LCD(s) from the commercial projector and see about driving them with a slide projector light source... The 3 LCD models could be tricky, though...

MHI is not the most efficient light. For that, you would need UHP, Ultra high pressure. It uses a high pressure mercury vapour. Also the arc produced is about half the size of that found in MHI. The unit will also produce whiter whites, using less energy, producing less heat. This is what is found in commercial projectors, and is why they cost so much.

http://www.sylvania.com/ProductCatalogs/ -> Product Catalogs -> Business Lighting ->
Browse Catalog -> High Intensity Discharge (HID) -> Metalarc Metal Halide -> Pulse Start-High Output,Less Color Shift -> '>150W' -> page 3 -> Product Number 64191
I just check price with my closest electrical supplies Nedco
price is very good 40$ lamp ( but not in stock )+ 62$ ballast
they can order this lamp but min qty. is 6
they have in stock m400/u/bt28 - but it less initial lumens ( about 36000 ) and mean lumens ( about 24000 )
Need 6 peopes, lets joint and by it.
If you intresting email me Vadim.Passynkov@pathcom.com

On the projector idea, I wasn't actually thinking of trying to stuff an MH bulb INSIDE the existing chassis, that's nuts. I was thinking of a little bit of dremel tool/hacksaw modification work, and building a light box onto the back of an old projector ... focus the light with a condensor lens, use UV/IR glass to cut the rays a bit, run the beam into the back of the old projector and off you go. Bit cumbersome, but should come out pretty cheap compared to how expensive 3,000-plus lumen overhead projectors have suddenly become.
Good point about the LCD electronics/bulb detector, though. Still, should be a way to rewire that, just fool the sensor into thinking there's a new bulb attached. Take a bit of experimenting, but should be doable.
On the light front, I picked up an M59 ballast for about $25 and a pair of 400 Watt brand new 4,000K bulbs for another $20 on ebay (both vendors have "lots more" they say, if anyone's interested), but it's one darned large assembly. Anyone know a good source of 400 watt metal halide HQI double-ended bulbs (4,200K) and e-ballasts? They're too expensive to ship up from the U.S. after duties/taxes, and that's the only place I've found the bulbs at the right colour temperature. The ballasts can be found pretty easily at aquarium shops, but they're twice the price of the U.S. ones - $250 range plus tax/shipping. I'm looking for somone in Canada who doesn't gouge on the ballasts...

As i have mentioned b4, Yellow page ppl
Eurolite has all the different types of MH HQI bulbs. They are located in Downtown toronto near the lake. They can be expensive but i never got a price quote.

But once again, I dunno their price or if there is a mininum quantity purchase. I wouldnt mind putting in an order for 6 double ended MH bulbs if we all want one.
I do have to say tho that my 175 watt is relatively small (130mm). The whole bulb is smaller than my 7.2'' lcd so my box desing is not effected.
