DIY Rear Projection TV - Page 20

penguinpaul · 13th November 2007, 04:01 PM

Just a quick question(s),
Im thinking of building a rptv but first I wanted to know some things:

Could I use the insides of a slide projector for the projection part?
I have an old OHP, should I use the fresnal lens from this?
And one more question, do you guys reccomend any LCDs? Should it be big or small, an in car one? 5-7 inch?

Many thanks,
Paul

yeh, i had the same problem when trying to get a projection panel - they were all in the US - And when I finally managed to get one in the UK (costed me 3 times the price of one in the us on ebay - £80) 3 weeks after having it, my little sister went and tripped over the cable, knocked the thing of my OHP, and smashed the glass!
