Designing another Magicn’t object (Hackpad)

So you might be wondering, isn’t this two project in a project?, well yes, but this is a series of communication device, the hackpad will be some kind of magical artifact that have buttons, and the wand is voice input

So this project is a universal control unit, that I can link with my other projects in the future, but I’m still wondering of what magical object/items that I can design the hackpad from
