homemade projector

this is my homemade projector again but this time i have added a condenser lens and it has made it about 3x as bright as it was before with the same bulb. remember to check out my indestructibles page to see how to make this. http://www.instructables.com/id/homemade-projector-cornflake-box/

what kind of lens do you use???

[porkypinekiwi]

@mtogono just a fresnel lens and a few magnified glasses, i dont really know what kind im just experimenting with it but try to get a real lens from an old slid projector it works great!

[kornboarder698]

not trying to put any of your work down but.... this can also be done with like a mirror and a projector lense from an old big screen tv.... i randomly found a few and put my cell phone and video camera screens up directly to the lense maybe 2-4 inches away to focus and it worked but was upside down and backwards but a mirror would probably fix that right up.....

[porkypinekiwi]

@kornboarder698 yes i know that but its not very bright, only the brightness of the screen

friend as you do to reflect the image? by a mirror? or a lens? thank you very much

[porkypinekiwi]

@forouruguay789 i dont really understand your question but there are no mirrors used in this projector only lenses. a mirror allows you to make the projector smaller so i will try that

[spidey90250]

How much would you sell one of those for ? Because I just don't have the time to make one . Thanks

@willbaguley9000 I'm sure a little bit of tinkering with the positions of the lenses (namely the glass lens on the front) would sort that, though!

[omardude39]

Hi there, followed your work on thisproject and I have to say, I'm really impressed!!! Glad it went well for you, and I'm making my own too :D

(PS. the English call it a "magnifying" glass [because that's what it does], and "indestructable" means 'can't be broken' ;) )

[MrKeBUM]

how much did this whole thing cost to make ?

[jawbreaker360]
