I am wondering how long it will be before people stop making interfaces for such projects with things like switches.
A lot of people would nowadays not think that way. It would be easier for some to write an 'app' for their phone/tablet, use wifi and some board that was a computer in its own right, e.g. a Raspberry Pi. Despite things like wifi being unfathomably complicated compared to a 'simple' carrier wave with some amplitude/frequency modulation (radio), the older analog ways are just too much physics. There might come a time when wiring switches to a PCB becomes as quaint as using valves instead of IC's.
After watching the video you almost feel sorry for the cardboard tank, much like how you might feel sorry for a squirrel missing its tail.
'Cardboard tank accidentally drives into inch deep puddle' would be a YouTube sensation (cruel...).
