I just knew I could put something like this together and had all the components (used a dollar store magnifying glass instead of the fresnel lens) but was really struggling. It turns out your lens in the tube was the difference for me. Too much light was getting to the lens. I added the tube and am so excited to have my own version of this terrific opaque projector. I managed to do mine with a piece of foam core board, a magnifying lens, and a cosmetic mirror all from the dollar store then a light fixture from Ikea that I had on hand, a CFL and a piece of cardboard I pulled from the recycle bin that I then rolled around my lens to create the tube. I appreciate the help!! I'm sure I'll be blogging about mine (especially if I make a wood one) and will be sure to link back to this post to give you credit for the final guidance.Julie {BuildSewReap}https://www.blogger.com/profile/08035505244057861379noreply@blogger.comtag:blogger.com,1999:blog-7583016308579611514.post-84407080757514445782013-03-19T13:35:58.711-07:002013-03-19T13:35:58.711-07:00We have not used either a fresnel lens or lcd lamp...We have not used either a fresnel lens or lcd lamps.
