eric Posted August 8, 2010 Share Posted August 8, 2010 The Forum has been pretty quiet lately, so I thought I'd fill the lull in activity with a little bit about the computer I integrated into my Oliver for those who have discovered their inner geek. The keyboard and optical mouse are wireless and run on batteries. The display is a Samsung P2370HD, a 23-inch 1080P monitor with a HD receiver. As far as I know, it's the smallest 1080P monitor/TV out there and weighs about 12lb. Unfortunately, it doesn't run on DC like the standard Jensen TV, I was unable to find one that fit all my other requirements (like a VESA mount) that did. But on the ProSine 2.0 inverter, the monitor pulls about 3A with the brightness turned down a bit, and less than an amp when on standby. Getting the DVI video through the overhead storage required a change to the factory connector panel. I found a reasonably flexible panel system that went in with just a little bit of hand modification. An HDMI connector would have taken up less panel space, but for some reason the computer I'm using produces a noticeably sharper image from the DVI port. There are also a pair of USB outlets in the panel and two coax fitings -- one F-connector for the antenna, and one mini-UHF for ham radio. The computer itself lives in the overhead compartment. The case is a VoomPC-2 enclosure for mini-ITX motherboards, with a M2-ATX intelligent automotive power supply. The supply can turn a computer on and off with a car's ignition switch, in my case I wired it to a spare switch in the panel by the door. Turning the switch off puts the computer into hibernation, turning it on wakes it up again. The motherboard is loaded with 4GB of RAM and uses a dual-core Intel Atom processor which has very low power consumption. The Nvidia ION chipset provides pretty good graphics capability, I can play DVDs and 1080P video files, and I hope to have Blu-Ray capability once I work the bugs out of the player program. Also connected via USB are a WiFi adapter (Zonet ZEW2500P) and a GPS receiver (Holus GR-213-USB), both stuck to the inside of the trailer roof to "see" through the fiberglass. Audio output to the Jensen trailer stereo is via an optical S/PDIF cable which prevents ground loop noise from getting in and produces excellent audio. I run Windows Server 2008 on the box, it's a lot like Windows 7 but without many of the extra gizmos that take up CPU and memory -- something you have to be careful of with the slower Atom processor. In addition to the usual computer stuff, the PC holds PDFs of all the trailer manuals, which saves space over carrying them around with me. There's also a good library of books, MP3s, and videos on the hard drive for entertainment when outside of civilization. Link to comment Share on other sites More sharing options...
