We’ve shared many house made projectors in the past, however we believe this may just be the very first house made 3D projector!
[Nicholas] has produced a wonderful compose up on this job on his blog, as well as in an Instructable, as well as even more details are offered on the original forum publish (in French though).
To sum it up though, he’s utilizing an old LCD from a damaged laptop, split into two halves. By utilizing a Fresnel lens as well as two separate optical lenses that are adjustable he can integrate the two pictures (top as well as bottom of the LCD) on the wall. then by adding a polarization filter to every lens, he can reuse the affordable 3D goggles from the cinema for his own configuration to see in 3D! This style of passive 3D does need a special projector screen to keep the polarization intact — he’s utilizing a Da-Lite Silverlight screen, whose metallic surface ensures the polarization is kept the same.
It’s a excellent job as well as is definitely worth inspecting out. If you’re in the mood for a smaller type factor projector, it’d be worth inspecting out this we covered rather a few years ago!
