This is Favi’s PJM-1000 mini pocket projector that may be the world’s smallest projector. The PJM-1000 somehow looks like 3M’s MPro110 but we are not sure if they are just the same device.
Favi PJM-1000 features 640×480 resolution with 80:1 contrast ratio, 12 lumens brightness and 0.656 throw ratio. It can project up to 100-inch of image. The projector measures just 4.4 x 1.9 x 0.6 inches and weighs 6.4 ounces. It is available for $279.95.
