Yea there are two steps to get a ps3 to output 3d.

Step 1: insert 3d bluray
Step 2: click play

Thumbs down Qumi Q5 melted plastic lens

Hi!

Has anyone who owns a Qumi Q5 had any problems with the outer lens melting? Am i the only one? It happened after cleaning it with distilled water while the projector was on. At first, it looked like the lens was loosing its coating in an oval shape and was in its upper portion. I then i tried to remove the rest of the coating using alcohol, i realized that the lens was being etched or melting on the inside where the light was going through it. It just does not make sens that this would happen with regular normal use. Since it was a factory refurbished unit the warranty was only for 90 days and is now expired. Vivitek wants over $200 to replace the lens (that i have already taken out). It really does not make sense to throw away such perfectly good little projector because of that plastic lens, and buying a new one or sending it in for repairs is not in the budget. I started a new thread but there was no response.

Anyone knows who their lens supplier is?

Linux powering the Q5

Hi All,
Having read that the Q5 has 4GB of storage I was amazed that I couldn't simply copy files from a USB drive to the built-in storage. I contacted Vivitek and they told me I needed a male to male USB cable (quite a rare thing, but available on Ebay). So I bought one and, sure enough, when I plugged one end into my projector, the other end into my Mac, went to the menu and found the USB storage option... it magically appeared as a (very slow) disk on my Mac. All good!

However, the more interesting thing (to me) was that there were already two files present:
  • localdata.tar.gz
  • usr.tar.gz

These contain a treasure trove of interesting detail about the Q5:
  • the drivers for the wireless rt3070
  • the Host Access Point configuration
  • scripts to control the HDMI and LCD
  • DLNA and UPNP configuration
  • The user interface configuration
  • Linux USB Gadget Framework
  • gstreamer and X windows

I'd love to know how to get a login prompt and update the Q5 with arbitrary commands and wifi drivers

Just for curiosity's sake I extracted the gdb binary to find out what linux architecture is being used:

gdb: ELF 32-bit LSB executable, ARM, version 1, dynamically linkedyb

If anyone has a firmware upgrade file I suspect there's a chance it could be reverse engineered to work out how to replace arbitrary commands.

The other thing I wondered about was, since they expose the device as a "Mass Storage Gadget" using the Linux USB Gadget Framework, do they expose the device via the USB cable as a "Serial Gadget" ?

Maybe getting a login prompt is as simple as using the USB cable and treating it as a usb-serial serial port.

Anyway, I thought it was interesting. I suspect the number of Q5 owners that happen to be Linux kernel hackers may be quite low but I just thought I'd let others know about the Q5's localdata.tar.gz and usr.tar.gz.

Cheers,

Doug

Computers not recognizing Q5 via USB

I've been trying to link my laptop via USB to the Q5 to dump a video to the Q5 USB storage space but both my PC and Mac laptops do not recognize the unit. I've been through the manual and cannot find any resolution. Anybody else run into this issue?

I've had no luck getting my computers to recognize my Q5 via USB. Matter of fact I exchanged my first unit and have run into the same problem with a second unit. Did you do anything unique to get your mac to work? At my wits (all two of them) end on this one.
