Popular Science writes 3M will debut their MPro110 mini projector by the end of the month for $359:
Images were discernable up to about 11 inches across, even under our bright fluorescent office lights. But they were definitely faded. And some movie scenes were downright indecipherable. The same went for photos. I’m pretty sure the prototype 3M loaned me at CES in January was brighter as I was able to demonstrate it during a presentation under bright lights to a few hundred people. But I’ll have to do more tests to know for sure. (Even if it’s less than ideal, kudos to 3M for making it work.)
In a dark room, it could project a big enough image to be the ultimate cheap-o home theater. The projector will sell for a mere $359. It doesn’t have a speaker, so you’ll have to get that separately. But really, how good could a microscopic speaker jammed into this thing sound, anyway?
