  1. DIY – Wireless USB monitor

    How to build your own wireless USB monitor - We took an IOGear wireless VGA device (GUC2015V), an M1-ATX, a Lilliput 10” monitor and a laptop battery to make a super hacked wireless monitor. If you spent more than an hour on this you could really make this hack usable. We couldn’t get more than 15’ of range out of this with line of sight, but it was fun to try. Based on the amperage of the devices, we could theoretically get a few hours out of this per charge.

    Other power supplies that could be used:
    The m3-atx is probably a better supply to use for this project.

    How much Power does this use?
    260 milli amps for just the receiver.
    1.1 amps for the receiver and screen.
    Our battery has a capacity at 14.8 volts of 6600mAH.
    Does this mean we get 6 hours of run time? Wow.

    Host CPU Loads tested on my desktop
    DisplayLinkManager is what does the processing for the Wireless VGA adapter.

    Hardware used for testing
    3 year old 2.8 Ghz Pentium D Dual core CPU
    4gb of Ram
    Windows XP
    800x480 output

    CPU Load Results
    0% - CPU load with an idle screen (desktop only)
    0-2% - CPU load with google talk
    2-3% - VLC movie paused
    9%-12% - VLC playing a movie

    Hi. My name is Rob Wray with MP3 Car. I told you we would test out this wireless monitor in the car, so for the last hour we’ve been goofing around in the parking lot of our office trying to get this to work. And actually it worked perfectly right off the bat the same way as it did work in our office. I just wanted to do something off-the-wall with it.

    So it’s working perfectly. I happen to have a Centrifuge help video loaded on the monitor right now. We’ve got a great wireless signal. We’ve done some calculations recently. We think this little hack job here can get about six hours of wireless time using the 10” monitor. So that’s pretty exciting. And we’ve been really happy with the video quality playback.

    The first thing that we tried to do to hack it, to make it look kind of cool and newsworthy was to hack in a USB HDTV tuner. So we did that. It worked well except the HDTV won’t play on this monitor. There’s certain things that don’t work well over ultra wideband USB and apparently the GT HD tuner that we sell in our store is one of those things that doesn’t work well.

    We also had some problems with getting StreetDeck to work well wirelessly over ultra wideband, but things like VLC which I used in my previous demo worked wonderfully. You get great frame rate playback, and that sort of thing. So I’m going to go ahead and start this movie here, and you can see that the picture quality’s pretty good.

    So we’ve been pretty happy with this as a solution. The only thing that we’ve seen is that, again it doesn’t support all video formats, and you also get – every now and then you’ll get a little bit of a wiggle over here on the left side. I’m assuming that’s from some type of interference that’s happening as a result of the engine alternator or various other little things. But it was happening before and now it’s completely gone away, so I think it’s almost unnoticeable.

    So try this at home. Thanks for watching our blog.
