Open source “split-flap” mechanical display
Genuine question: what are some practical advantages of a split-flap display over, well... any other kind of dynamic character display?<p>The only two I could think of are:<p>- they don't emit light, so maybe there could be some kind of light-sensitive situation where this would be required (though in that case e-ink would surely surpass it).<p>- the sound passively-alerting those present to updates. It's not obtrusive or attention-getting like a bell or spoken announcement, so only those wishing to notice the updates can listen for the sound, while others can go about their business unperturbed.<p>Anyone know of, or could imagine any others?
