To show what can be done with hacks, I’ll cover several of the most useful documented hacks. The closest thing to a centralized site for information is the Kobo Hacks and Utilities Index, but do a web search for additional scattered information. Note, too that the Kobo Clara HD (Figure 1) and Kobo Glo HD seem among the most popular models to hack. Other models may or may not be open to all the modifications supported by these models. Use at your own risk.
