As follows, you
can find real projection results of my do-it-yourself-projectors
The documentation to built your own Home-Cinema-Projector today included 65 pages, different Vides and additional material such as online access to updated new variants. It included 5 realized variants of self-made LCD-projectors. All described variants were based upon standard Overhead projector-technology - ensuring that nearly everyone can built such a projector without having specific electrical engineering knowledge. The parts/building materials being used to built it, were described in detail in the building plan/documentation. Such parts can easy be bought and are easy and cheaply available on the market. Every single step, how to built it by yourself, is precisely explained (including detailed photos for each detail).
Altogether, hundreds of photos and illustrations are contained. Additional, numerous photos in high resolution, as well as some short videos around the projects are included, too (containing further Information and explanations around the building-process, picture-results of the diy-projector-setup etc.).
Everything is explained, simple and easy to understand - even for beginners.
If you like to
have your own Home-Cinema at low costs, with low running costs,
here you are!
The shown picture-quality of the photos
is much better in reality! The reason is, that the digital-camera,
used for the photos, has some problems with the correct autofocus
and color temperature at such difficult photographing-conditions.

All photos shown here, were obtained with a commercial, standard TFT display. The light source used for projection is a standard transmissive Overhad projector, everyone of you knows from school. Instead of flip-frames, the modificated TFT/LCD displays are used as transmissive display, mounted e.g. on top of the overhead projector. All shown picture-results are reached with standard Overhead-Projectors (transmissive variant, not portable briefcase Projectors with light source in the head of projector).
Those recommended OHP-Projectors are really easy and cheap to get. As well as the standard TFT-Displays An other plus of this solution: You can realize your projector in a short period of time successfully with high picture-quality (depending on chosen variant, building time lasts from about 1 hour up to about 2 days).I recommend cheap OHP-projectors starting at 4.000 lumens for appropriate brightness and contrast in non-completely darkened rooms)
Not least because of the good picture quality and the simple and very cheap standard-components (overhead-projector and standard TFT-Display), I exclusively describe variants based upon this idea (resuming other variants with smaller projector-housing are mentioned, too and can be studied from given information-sources (refer to included links on external sources), if necessary).
Note: The documentation with additional
material such as explaining video-clips and more Photos, can also
be purchased alternatively
on CD (no additional
costs for CD-Version). The printed version doesn't include those
The two pictures
above show variant 2 - with a projector-housing and a the desktop-TFT mounted
on top. The Overhead projector and the TFT display including electronics
are now integrated in a wooden roll- container. The other variants
(Panel-variant and the latest version with mini-TFT) don't need
such a housing. But it makes the setup more "living room-suited"
and mobile (if not always needed, just make it disappear by moving/hiding
For the second of the described variants to built your diy-projector, a deflecting mirror (format 40 x 30 cm) above and opposite the Overhead (here not in the picture) serves to project the picture side-correct (caused by specifications of this single variant. See 2nd line/column, left picture in the thumbnails shown on top of this site). This doesn't concern the other described variants in the document.
By the way: Those of you
a pc-based picture-source with Nvidia graphics accelerator card
(like the Gainward FX 5600 Ultra) don't need deflecting mirrors.
In this case, the software-drivers itself can can guarantee horizontal
realtime software picture mirroring.
Illustration: Here, you can see a tangential fan, mounted besides the TFT. It is cooling the display only from above, which proved to be absolutely enough. Display stays handwarm. Such a fan provides small measurements combined with low noise and high cooling efficiency. Now, my used ventilation fan from the initial testing phase became redundantly.
Want to learn more about the different DIY Projector building variants? More than 30 different ways how to built your own projector were included. Starting from simple VGA, SVGA self-made Projector variants up to 1080p resolution variants, different Methods for all needs are included on this CD-ROM. Even high quality native HDTV variants up to 1080p Full High Definition Resolution and even 4K can be realized, nowadays.
