(If you find a way to buy them i would greatly appreciate you sharing it)
PS : These cells use 200V DC to work so your project will need a DC-DC converter. You can search for similar speccs to the official one on aliexpress or whatever https://metec-ag.de/downloads/dcdc-converter-5to200v.pdf
Finally you would need a brain for all this which could be the raspi directly or you might opt for using the raspberry-pi (for the ebook manipulation, character-to-dot conversion etc.. unless you decide to pre-format the files) in conjunction with an arduino (for the signal transfer/propagation.. you know sending the )
Take a look here for some software inspiration (it also explains the signals the braille module would be expecting but you are better off looking at the Datasheet for anything serious): https://github.com/bertrandmartel/metec-braille-driver#more-...
Good luck.

A nice video from "Applied Science" about a one Cell driver DIY project (He is i believe, using the P16 cell from metec) might help you decide whether to buy a backplane-driver or make your own [also the idea or putting a push-button underneath the braille-cell might be interesting to you for a selection mechanism maybe?] : https://www.youtube.com/watch?v=Ss-Fux86doQ
