you are finnished now (update) i found a heat sink and installed my 20w led its not that much brighter but i think i can fix that by adjusting the con...
i will show you how to make a homemade projector using mostly things you can find around the house. (remember to read the whole thing before you start because i am adding new info at the end as i learn more, im a beginner 2)
Step 1: What you will need
you will need a large cardboard box, i used a cornflake box, you need a fresnel lens and a regular magnified glass i found the fresnel lens at a shop advertised as (credit card sized magnifier) for about 5 bucks and the magnified glass should be about 2inches across, you also need a bright light, the brighter the better but led is good because it needs to be cool or else you will cook the lcd i got the lcd from ebay for $28.00 and it allows you to plug anything into it. you will need a round cylender the same width as the magnified glass (i used pringles chip container) the last few things you will need are aluminum foil ,tape and scissors.
i bought that square looking led light of ebay for $20 but i cant use it yet because it needs a heat sink and fan, the other one runs cooler. 12v
