Most likely I will get a Belkin 50w 120v inverter to convert 12v into 120v.

USB devices plug into the receiver cannot be detected by the PC. I had installed all necessary driver but no go. Found out there is a network adapter under ASUS WAVI wireless USB device that had been disabled but I can't manually enable it.

As for the distance, I test out 720p and 1080p. 720p 60hz (without 3D) work perfectly up to 14 ft before I start to notice some compression artifact in the display. 1080p 60hz is around 10ft. Note that the device still work after the above mention distance but you start to notice degradation to the video.

I try out few games and no perceptible lag at all. So far, I'm satisfied with ASUS WAVI performance and I would recommend it for 360 degree FPS gaming. I also try to power both transmitter and receiver with a single XP18000 battery pack without problem (one connected to 9v-12v output and another using willy cable to stepdown 19v to 12v). Based on my estimate, the battery pack should be able to provide enough juice for at least 2.5 hours gaming with a single charge.

Thanks pierreye for the info. Sounds great for a single room wireless solution without resorting to a backtop! I had hoped that it might have a longer range (10 meters or more) but it's still useful at 10ft. Too bad about the USB, but there are plenty of wireless USB extenders.

This is good news! I want to use your wiimote/navigator/sharpshooter gun combo along with the HMZ-T1. Now you can put the control box for the HMZ-T1, asus wavi receiver, and battery pack in a small backpack and have total 360 HD 3D VR gaming!! AWESOME!



Can you post a link to the one you get?

Here's the inverter:

The receiver box actually is quite big but light around the size of wii but thinner. Still manageable with a backpack but make sure you have good ventilation as I can feel the heat from the bottom of the box. To extend the range for FPS, you can mount the transmitter on the ceiling just above where you stand. This should double your distance.

@pierreye: Hey I'm curious what the battery life is like using the Wavi. I would hope that you would get a much extended battery life versus using a power hungry gaming backtop. That and the fact that you get the graphical performance of a high powered gaming rig (without wearing one) really makes this a compelling component for a single room wireless VR setup.

I will try my Asus WiCast as soon as I can to see if it supports 720p 3D 60hz. I also have two other WHDI units on the way (Made by BriteView and HP), I will test with those as well.

My WiCast does a lot better than the Wavi, it sounds like. I can get 60 or 70 feet, even with a wall in the way!

I'll do a battery test after work. Will run both transmitter and receiver through the fully charged battery estimated using 24w x 2 = 48w (HMZ-T1 rated at 15w).

I'm curious what the range of those other systems is. I had hoped the range might be similar to Bluetooth but maybe that's not possible with WHDI technology at this point.

It is certainly possible! Like I said, my WiCast gets 60-70 feet, and it uses WHDI. In fact, the specification has support for ranges of over a kilometer! No consumer products are available with that kind of broadcasting power, though.

Manage to power both transmitter and receiver around 2.5 hours. Should be good for at least 2.5 hours gaming.

Can't wait to hear your review on these! If these others can transmit full HD at a greater distance, that would be awesome.

IOGEAR has a device like this launching soon:

Dismantle the ASUS WAVI today due to some intermitent transmission issue and I found out actually the receiver board is quite small about 1/3 size of the casing. The other 2/3 actually is occupy by wireless USB PCB. Also found out that the intermitent transmission issue is due to the heatsink is not mounted properly on the chip maybe due to heat. I remove the wireless HDMI pcb board from the ASUS WAVI casing and mount it to a smaller ADSL plastic casing, remount the headsink and found out I got better range around 20ft from the transmitter before the video quality start to degrade. Another advantage is less power consumption as I remove the 12v and 5v power supply to the wireless USB board.

Next mod would be removing HMZ-T1 AC transformer, mount a DC-DC stepdown regulator that will take 8v-40v in and output at 5v 3A. Then mount both HMZ-T1 control box and ASUS WAVI wireless HDMI PCB into a bigger plastic casing as one unit.

Great idea. Longer range, less bulk, and longer battery life. Sounds like a win-win situation.

Awesome work! If at all possible get alot of detailed pics while your doing all this to help others in the future.

Here's the photo. Removing the board is simple. Just take out the casing, remove 2 screws and the power cable to wireless USB board.


Size comparison.


Reducing the size and weight.


DC to DC converter. 8v-40v input, 5v, 3amp output. You can get this from ebay.

Nice.
