This kit comes with everything you need to assemble your own Time Circuits Display! It looks almost identical to the one seen in the Back To the Future Time Machine Delorean*. The LED displays feature our custom 14 and 7 segment displays in Red, Green, and Yellow – which are the only ones on the market that are sized and spaced to properly resemble the ones in the movie.
The control board includes an ESP32 module, which can connect to WiFi, and get accurate time for the Present Time from an NTP server. Of course, you can also enter your own Destination Time via the number keypad, and “Time Travel” to that date.
Here’s how it works:
Display colors are more vibrant in person due to the nature of multiplexing, and camera shutter speed.
For 3d print orders: Parts will come unfinished. They are printed in a fine layer height in silver, and green/white for the keypad. The keypad shown in the pictures here is not painted, but the enclosures are sanded and painted.
B-grade 3d printed parts : These are parts that have imperfections that may require additional sanding or filling to obtain a smooth finish. They are not deformed beyond usability, but didn’t make the cut for A-grade. Between 2 -4 parts will be B-grade, while the others will be A-grade. Everything else is the same.
We do not recommended installing these parts in a car since PLA can warp in the hot sun. If you would like to do this we would recommend either printing in PETG/ABS or purchasing LMB aluminum boxes & having the outside enclosure fabricated. The TRW keypad can either be printed in PETG/ABS or resin cast.
Alternatively, the 3d printed parts are available to print yourself here.
Note: Kits are currently assembled to order and require an additional 2-4 business days to process and ship. 3d print orders require an additional 5-7 business days, currently.

*There are some small differences from ours when compared to the movie:
- The bottom of the enclosure housing is level with the display enclosure so the display can more easily sit level on a table
- The display enclosure housing is 3″ shorter in depth, and does not have the wire screen on the back
- The lenses in the TRW like keypad are slightly different (although Linrose B1050N lenses that look more like the original can be used if you want)
- Some month characters are impossible to duplicate with 14 segment displays (like the D and some N’s) because the ones in the movie were not actually segment displays, but gels that were swapped out depending on the month that they wanted to display.
