Making the case is the “rest of the fucking owl”, like there hadn’t been a successful attempt at making silicone membrane keypads found on cheapest TV remotes in homebrew hardware scene.
Edit: my plan was to find a configuration of hardware that does what we want to do first. Next would be trying the new platform from a desk and, if that goes well, designing a case for the parts we selected. You can't really make a custom case without knowing what's going inside :)
The case doesn't need to be special for a first pass. We just need enough of a fucking owl to decide what to do next.
