Obviously, the most representative fictional hardware in the film back to the future is doc Brown’s DeLorean dmc-12 time machine. However, we must agree with [Jason Altice] of codemakesitgo that the second most memorable gadget is the improved Futaba remote controller, which is used to control delolin from a distance. Now, thanks to his detailed construction guide, you can build your own version of the time machine controller – including the working speed readings.
Now it is clear that [Jason] does not claim that his construction is particularly accurate. It has been proved that the actual transmitter used in the movie props, Futaba PCM fp-t8sga-p, is difficult to find and expensive. But he believes that most old-fashioned two leaf transmitters are visually close enough for casual observers. The more important part is to remake the additional gear that doc Brown attached to its version.
To this end, [Jason] can find some screen precise hardware to equip his transmitter, such as the unibox 140 project box and the metal 9V battery clip. Other components, such as the illuminated Molex 1820 switch, are more difficult to track. Fortunately, we live in an era of cheap desktop 3D printers, which can easily produce impressive and accurate replicas.
Of course, the most prominent function is the Seven Segment LED speed indicator. Each number is a separate 25 mm (1 inch) sc10-21srwa display mounted on a custom PCB with the tm1650 controller. The Arduino uno in the unibox 140 drives the display and uses the remote reyax Lora rylr998 module to receive speed data from the transmitter in the vehicle.
[Jason] built a “speed box” equipped with GPS, which is very similar to the movie version, although there are three functional numbers, but only two of the original props. Internally, it uses the same LED display, Lora module and Arduino uno as the transmitter. We like this method, that is, keep the hardware more or less the same on both sides of the link to make things simple and beautiful.
Now, of course, you don’t need a delolin time machine to test the remote controller you have completed, but we are grateful to (Jason) for taking pains to rent one so that he can show his creative style. The final product looks great and ranks first with the copy time circuit in the list of bttf props we hope to display on the shelf.
