Some pictures of the inside of the Open Frame version, to better help understanding the assembly.

I bought mine here: https://www.ti.com/store/ti/en/p/product/?p=DLPLIGHTCRAFTER
It seems that unfortunately, this model has been discontinued: newer models, however, do not have the same speed (up to 20Khz), unless you use very expensive ones.
A search on Aliexpress https://it.aliexpress.com/item/1005003288217818.html suggests that probably they can still be found, but at higher prices (it was about 6-700 some years ago).
At some point I was in touch with Keynote Photonics, as they were developing a projector base and the same schematics. The product was called https://www.keynotephotonics.com/lc3000-g2-pro-lightcrafter/ , but it seems that now the optical part has changed.
Currently I am searching for alternatives, that maybe are cheaper and easier to get.

It is not easy to keep a whole class interested in a lesson. Sometimes it seems that students are just bored and they are not absorbing any of the information you are hardly trying to teach. A suggestion can be to talk less and involve students more. The more the class is interactive and the more technology is used, the more students will enjoy what they are learning, because technology is what students nowadays live and breathe every day and they love it!
VVD: Volumetric Visualization Device, becomes a great tool to support the teacher in different ways like:
- explaining and developing students three-dimensional visual and sensory perception;
- representing complex concept like mathematical or chemical formulas in their three dimensions;
- display body parts, artifacts, animals or any 3D model that can relate to your lesson, instead of using mere pictures.
Students can move around and fully understand model proportions. More people can watch the same model at the same time, encouraging discussion and opinions exchange with the teacher or among the students.
Museums & Exhibitions
The museum of the future must become a center for the community, a meeting and conversation place, where the public is involved in a continuous dynamism.
Normal display cases and graphics are more and more supported by videos, interactive displays, VR experience. When in need to show artifacts or archaeological finds which are not present in the museum but are related to the ongoing exhibition, museums make a wide use of pictures, drawings, schematic images.
VVD is a new affordable tool to make an exhibition visit more absorbing and interactive, to grab the attention of the public on special pieces we want to highlight. The front screen allows you to add captions, images, video and more information about the 3D models you are displaying.

VVD can create a new disruptive way to look at 3D imaging generated by 3D scanners or magnetic resonance scanners and computed tomography (CT) scanners , which can now be explored from any point of view, without additional glasses, opening up to endless applications in the medical sector and bringing key benefits such as:
- Increasing patient awareness and education, with a much easier to understand visual explanation of the undergoing procedure;
- Increasing efficiency and less unexpected issues in the operating room, since a surgeon can see a better 3D visualization of the involved body parts, allowing for a better understanding and preparation.
- Medical experts can now study, discuss with their colleagues or explain to their students real case studies as 3D volumetric visualization that can be explored from any point of view, as if it was a real object in front of them.

This was the first picture of the working VVD. You can see 2 Nema motors, and the oscillating arm on the left. How I got it to work?
I can share this image since I started submitting for a patent, but in the end, I gave up. The project, which I developed all by myself from scratch, was still a prototype and not yet commercially viable product, I did not have marketing power to push it, or to involve some big companies, so I stopped working on it.
Back to the picture, my solution was to have a rectangle of film for rear-projection, inside a thin plexiglass frame (100). It was suspended with 4 rubber bands on each angle (101). They were connected to two oscillating arms (102) moved up and down by 2 (or 4) stepper motors (103). By sweeping up and down the film, a volume was created (143), and by projecting a different image when the film is in a different vertical position, a volumetric image is created!

I made this short presentation some time ago, when I had the idea that the VVD system could also make a very cool interface in cars! It needed some optimization, sure, but I still think that it was a nice idea ;) Lumi Industries was the name of my startup. Unfortunately, the VVD did not became a commercial product.

After working on the VVD for several years, I found during an Internet search that this company, Voxon (they are based in Australia) has made a very similar device. There are some differences, however, in the motion system used on the VVD with the oscillating motors (that is not perfect, as you have to change the rubber bands after a ful day ;) ), and in general, their device is much more refined!
The VVD is a protoype, and I have designed everything by myself, including all the Cad design, electronic design, writing of software and firmware, documenting with photos and pictures, and (trying to) promote it; in this task I kinda failed, since it never became a commercial product! ;)

Working on a real three-dimensional visualization from every angle, VVD can help you get a better general view of your assembly of components, checking that all of them are right, proportionate, their coupling is correct. You can even review it with your colleagues, because you are all watching at the same time, anyone from his personal point of view.
