It is stupidly expensive, but the vestaboard is pretty dang cool for home or small business use, if 132 characters will suffice. No affiliation, I just like em
I would love a smaller version for my home office. Not sure what I would use it for. Maybe some app monitoring info.
And ear.
These things are loud. It is actually a feature in airports and train stations, as it signals that the board is updating and it is worth taking a look, in case there is a delay or something.
But if you don't want a loud notification, these things may get old very quickly.
