Hi Skip,
Yeah, I think we're on the same wavelength. That's pretty much the kind of system I'm specing out for Temptress. We don't have your power budget, being so much smaller, but it pretty much takes that kind of horsepower to do heavy graphics processing... Like moving around a chart (with 2 or more open simultaneously) That's one strong reason for dual (or more?) displays. I have eight USP ports on my desktop system, with 3 or 4 hubs (who knows for sure any more - I'm not going back there!) That's just for a home computer. No GPS, wind and water sensors, depth scanner, etc. And so the question arises - how to keep USB connections - connected? Even on this stationary box they tend to work lose over time. Richard PS: Strange how it works out that way so often. I no sooner asked about 12 volt monitors - than I came across one - at the local CVS, of all places. Craig 13" TV, but has all kinds of inputs (including VGA). $149.99 - on sale for $99.99 I don't know how well it works. No brightness, contrast or field of view numbers on the box. But it did claim 8ms update rate. And it uses a 12v wall wart (2.5A) for power! Paradise is no inverters? Skip Gundlach wrote: Hi, Richard, Gordon, Larry, Bob (cc'd), et. al... If you're a geek, you can probably build one like Bob Stewart, at islandtimepc.com did for me (I'm a geek, but his CS is so amazing, including getting me up and running in WiFi before I was even a customer, at great personal effort on his part, when legions of supposedly knowledgeable folks in several newsgroups and forums could not, that I felt I really needed to give him the business - and you already know how I feel about his WiFi setup which I use now). Mine has 8xUSB (2 front), 5xserial, 2xLAN, hdmi, HDI, VGA, a dedicated filtered 12V out (to power my 12V devices that won't run on boat power, like my HDs - 1x 500G, 1T, 2x 2T, and my Vonage phone chargers), front and back sound in-outs plus line in on the back, PS2 mouse and keyboard inputs and firewire (front). Dual processor 2GHz, DVDRW, 500G 2.5" SATA, 4G RAM (ya, I know, windoze doesn't support more than a little more than 3, but the parity/dupe in 2 chips made sense). About 2.5A, unless my conversion to 2.5" from 3.5" drive (in about 2 weeks), with their 2.5W vs 15W 5V draw makes a big difference (dunno until it's installed and can check the in-use draw). He includes a 135W 19.2V brick for when you carry it ashore, as I do, and the pigtail for boat power. Of course, an OS (mine is XP), and all the usual OEM add-ons for playing with. LED monitors are mostly 12V, but require - if they have provision for it at all - the newer, larger (vs the common 100MM VESA) mounts if you want it on the wall. Not all that pricey. Some don't have removable bases; that's a must because we watch our movies by moving the screen from the Nav to a shelf, switching from HDI to VGA (nav station has the HDI cable; aside from my current mouse/keyboard, which is IR and has a puck on a USB wire, you see no wires in my installation), picking up the VGA cord from under when we raise the shelf from a seat back to shelf. My screen and (laser - inkjets run!) printer are all that remain AC at the moment, and I'll seriously shop for an LED screen when I go ashore again for a wedding in the spring. Router, WiFi and computer run on house power (10.5-18.5V); I have a separate 5V PS for my powered hub and Vonage base. The only thing you see of our computer is about 2.5"x4" out from our bulkhead of the 11.5" square x 2.5" tall case, and even that's partly hidden under the screen, which stands out from the wall. You may not require all that functionality, but I did, so he built it that way. Drop him a line at , or go to his website and get his phone number - he answers his own phone - and give him a call. Let him know what you want in a box, and he'll tell you how much it will be... OTOH, if you want something you can drop in the ocean or take a boarding wave while you've got it topside for your nav program like a boater I met does, check out Itronix laptops which are coming back from Iraq, on eBay. Touchscreen, waterproof, sandproof, dropproof, swappable HDs, GPS and WiFi, yada yada (see prior discussion in this space about them)... L8R Skip -- Richard Lamb |
