One of our customers decided to take model-making to the next level.
Based in New York, USA, Carl Darby set out to create a scale model of the EVA Pod from the Movie 2001: A Space Odyssey – a 1968 epic science fiction film produced and directed by Stanley Kubrick. Not content with simply backlighting the panels, he wanted the panels to be animated just as they did in the film.
Using the 1:8 scale model kit from Moebius, Darby needed to find small enough LCD screens that he could program and add into his model to replicate exactly the video screens seen in the movie.
He’s documented his progress on his social media pages and hopes to share the process with others so that they can do the same.

The EVA Pod has 6 screens in total, 2 screens in the centre and 2 on each side.
Ideally wanting to use the 0.96" micro OLED Display for all 6 screens, Darby was restricted by the model’s panel area and was only able to use the UOLED-96-G2 for the 2 centre screens. The 4 side screens required a slightly larger display area than the 1.7 inch, for which he used 1/8 inch generic tfts.
“It was a shame about the model’s side screen size restriction as I would have liked to use the UOLED-96-G2 for all 6 screens. Having the onboard video processor and microSD card included on the screen’s board means they are very compact. The programming software is very intuitive and easy to use - especially compared to the Arduino programming I had to use for the side screens. The side screens need a circuit board and a separate Arduino Uno to control them. It’s not ideal when trying to create a kit & instructions for others to use” Darby explains.
For the 2 front screens, Darby programmed the animations using the 4DGL graphics function and saved them onto his micro-SD card, which was then read directly by the unit’s on-board micro-SD memory card adaptor.
“As I was coming across programming and technical questions, I’d reach out to 4D Systems team via the support forum and was always able to get an answer to move forward with the project. For example, the 2 front screens play a 2-minute clip on a loop. One of the 4D Systems forum moderators made a program for me so each time you power on the screens they play one of 3 videos” Darby continues.

- Outcome -
Recording the model development’s progress on his social media pages, the 6 video panels display in colour and refresh for new charts and text displays.
But not everything was smooth sailing.
Darby had to design a power supply that could be completely enclosed within the model as well as design & 3D-print parts that would match each of the 6 screens to the EVA Pod kit.
“This project showed me how easy 4D Systems products are to use. Unlike the front screens, the generic tft’s I used for the side screens needed a circuit board and a separate Arduino Uno to control them. The SD card on the genetic tfts had resistors in, which slowed the data transfer so I modified them and had to make a custom circuit board to allow a fast enough frame rate to play videos. You can see why I would have preferred to use UOLED-96-G2 for all screens” jokes Darby.
