You should be able to open the project in the Arduino IDE (I think I was using version 1.8.2) and just build it. What kind of errors are you getting? Have you selected "Arduino/Genuono Uno" as board?
If you build something similar to oel (above in the comments) based on NodeMCU you could make it talk to an android app. It would indeed be a nice project, I'd expect it to take some time to implement properly though. Best of luck!
Hmm. Hard to say exactly what is going on. It almost sounds like there is something going wrong with reading from the SD-card a bit into the plot file. But this seems strange though since the whole file is parsed before starting the plot (to find min-max coords). Have you tried a different SD-card?
If it is plugged in to a reliable power source that should not be the problem either. When running on batteries you're always at risk of running into low voltage issues where the Arduino would reset.
