HI Lesko,
thanks !
I´m using an Asbestos replacement wich aisle the heat really well. I must tweak a little the air convection (I must add some intake holes in the back side and assure outgoing air is not retrofitted (feedback). I´m using 2 pieces of normal 3mm glass. I need to add some UV filtering soon to protect the LCD.
From condenser back to first fresnel the distance is 16cm.
thanks !

Hi IEF !!
Thanks,
The hot air is exhausted from the top side. There is a 10cm x 10cm vent hole.
In the first photo on page 2 you can see the Light box fan have an air convection tunnel towards the top (aisled with asbestos because the air coming out is really hot. The Panel Box fan only have a metal tunnel (without asbestos) because the air is just warm.
it´s on a test period, it may require some redoing with a better design.
You can see the top air vents here...

Very nice setup.
What is the result with light in the room,can you post a picture.
Where did you buy your condensor lens.

Thanks, Thats are test pics because I´ve not received the First Surface mirror and I´venot fixed the lens.
I´ve to build the focusing system and I´dont know how to make it yet.
i´ll be posting definitive results with a FS mirror and a well focused projection, as soon as the mirror arrives.
I´m testing a normal Plano Convex lens from SurplusShed hoping it resist the heat from the lamp because is not tempered.
I run a search on Surpushed.com for PCX lenses within 50mm to 150mm diameter and 50mm to 150mm FL and just pick a 90mm Diam and 100mm FL lens.
I am very impressed with this projector. The build quality is amazing. It is the first lilliput PJ i have seen using a 400 w bulb. Makes a huge difference. Looks very bright and clear. Especially for not using a first surface mirror yet. I am sure that will make it look even better.
Great job. Post more screenshots when you get a chance please.
Take care.

do u mean that an HQI without UV filter can destroy LCD after some time of working?
I'm using benq fp567s and HQI 250W
Yep, UV damages lcd's, the colours will fade if the panel is exposed to a lot of uv and the blue will go first, so a good idea would be to get a uv filter or a bulb with uv stop, so your panel will live it's full life.
FS Mirror arrived !!!!!
I've taked some pics tonight with the FS mirror just arrived !
Thanks. Regards.
The mirror has just arrived today. So, I put it on the projector but I'm afraid it is not aligned perfectly at 45°, just for a test run.
The lens is not fixed nor mounted yet on a focusing mechanism, so it's hard to get the image completely focused.
Thanks mccamp82 !!

Gracias compatriota !!! saludos desde aqui !!
Thanks. Regards.
I've read in some other threads on the forum that high wattage MH lamps generates too much UV light that an damage or alter the panel on long tie exposures. So, I'll need to get the filter soon.
