How do you go about setting up a custom device file like that (/dev/whiteboard)? Is it just writing a device driver?

I think you could just hook up an old pen plotter to your whiteboard.

[EDIT] whatever it has been done before:

But this of mechanic is certainly unique and adds a lot of clumsy robot charm.

Wonder how easily you could store human inputs with a kind of (reverse) Pantograph type device for reproduction.

The author says the device is a USB modem. So, under Linux, the author could have simply written a udev rule to use the name "whiteboard" for that particular USB modem's device file.

And even under plain-Jane Unix, you can name a device file whatever you want.
