This is a small diapositibe projector I have designed to be inserted into a Booknook. It can project a diapositive down to 10cm. It is designed to work with two 30mm lens with 30mm focus, like: https://www.amazon.fr/gp/product/B07HJ915R5/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 The source light come from a 1W white Led like: https://www.aliexpress.com/i/4000338065818.html It uses magnets (8x3) on the Diapositive holder to allow eazy trimming of the focus, as the three parts are mounted on an iron rail. Once the focus is obtained, I glued the diapositive holder with glue pistol. The sources and the mirror ellement can either use magnets or just screws. The distance between the source element and the diapositive is not critical, only the distance between the diapositive and the lens contained in the mirror element will affect the clarity of the image. (Note that an extra lens can be added, after the mirror to improve the overall focus.) Enjoy !
