So me and GepperRankins set to work making our LCD projectors a few days ago, his stuff arrived first so we made his and its cracking good!
I did break his bulb, but I got him a 300watt halogen and its working.
As for mine:
Mistake 1) I let someone else select my projector. Its one of them mirror one's that has only half a fresnel backed with foil. It's rubbish.
Mistake 2) I thought i'd brighten things up a bit. I removed what i thought was grey plastic, remembering as I did it that LCD's have 2 magic bits of plastic that seem to effect light in odd ways (I was about 10 when I took my last calculator appart so it was magic then)
The plastic was infact one of the polorisation layers :-(
It did make it brighter tho, but I think another projector is required, or a cheap 15" fresnel.
So, instead of re-attaching the poloriser, could I place it just behind the screen? Would that work? Or do I need a new TFT? Thats my question.
