i have not played with these diy tv projectors in some time now, but if your just getting started with them, then just pickup a cheap fresnel lens from office depot or what have you and build a cardboard box to hold the lens in front of your crt tv.
 
as for the backwards picture. only safe way is to flip the tv. if you really want to you could open the back of the tv and switch the 2 wires... i did this once on my small 14" tv when i first started in this hobby and it worked well. it also corrected the mirror image so you can read text properly ..

Hi I have been researching thease projectors for about 1year (roughly)
now and am trying to build one but the problem I am haveing is getting
the lense (which I can't order online) and also figuring out how to
make it so i don't have to turn the tv upside down (its ok if i have
to) But I am Trying to get the best quality of projector of this type
CRT TV (not lcd) for the absoulute lowest price and would love it if
someone had a lense I could have for free or for cheap (I would have to
send cash tho)I am doing this for use in my bedroom which is in the
basement and only has one window which I think I will cover up with
Black out cloth And the reason I can't order online and have to send
cash is I am 14 years old yes It's true but am really smart I program
computers for fun and would like to give this a try. Thankyou please
reply soon!

If you open the back of your TV make sure you discharge it correctly otherwise you could end up....DEAD. ;) joe pickles <dr_bev780@...> wrote:...
