Earlier quoted context omitted.
It uses a small CR2320 battery. To access the battery you'll need to remove a sticker on the back cover, and then the battery is glued in with hot glue, so you'll need some pliers to remove the glue, and then you'll need a small tool to push the battery out of the circuit board. Rest assured, it's not going to be an easy battery to remove.
With children, that's a risky belief.

Yeah, this hadn’t really occurred to me when I initially designed it. But it’s now my largest concern as well.

#12@OP: Show HN is for things you (i.e. the person submitting) made, and also explicitly not for crowdfunding: https://news.ycombinator.com/showhn.html
I’m not the OP, just the project owner. Although I did do a Show HN when it launched.

#16I love the 'fridge light' NOT page.
It wouldn't take much more to make this useful for older people, e.g. farther non-obvious separation of buttons (e.g. across pages), or in time. Humans are really bad about associating unrelated things from too few samples or missing recurring things just outside our window of attention.

#17Thanks for posting this! I’m the guy behind the project, and I’ll try to answer any questions about the project here.
Nice job! From the video it looks like many of the pages share the same buttons. I'm curious how you detect which page is open to operate the corresponding circuit?
Re: Computer Engineering for Babies Book
#18Nice. And why didn’t I think of this? Ha ha!
