When you plug it up to a Mac, Spotlight takes over and creates a few hidden “dot” files on the USB file system - which then render it dead!
This blog post is just a placeholder to document my attempts to convert video on a Mac to use in the UltraProjector.Ī bigger problem, though, is that bogus files on the UltraProjector file system make it lock up. Some intense research showed a secondary program, ViDrop, which could create videos - maybe - and it was a graphical frontend to “mencoder,” an open source converter program that is also available for Mac. (UltraProjector identifies itself as “ROCK MP3” and uses a China made chipset called Rockchip.)

First, there seemed to be only one program in the known world that could convert files that would play on it, and it was only available on Windows - some AVI Creator program, available as a free download. I evaluated one of the prototypes and made the decision to order four of them when they began shipping, and we used them in several Haunted House attractions here in Des Moines, Iowa.īUT, I quickly found out these units were not at all Mac friendly. Simply convert video to the proper AVI format, copy it to the device via USB, then turn and and watch it endlessly project the video clip(s). (It was originally $149, but today is $199.) The unit, which began shipping in October that year, was a totally silent, self contained low resolution projector (320×240) with audio output. It was designed for use in things like Halloween haunted house. In 2009, I stumbled across a “coming soon” solid state digital projector called UltraProjector.
