TV Tuner - External for WinXP
small-LCD-screen flat panel TV, cable ready.
A much better option. The screen is optimized for a TV signal, and has a much wider viewing angle. Some boat friends of mine went the laptop TV card route, and were endlessly fighting over whose head got to occupy the "sweet spot" in terms of viewing angle. I have a Samsung 150mp and am very happy with it. Very electronically quiet, doesn't foul up HF reception. Magnetically inert too. The speakers are kinda tinny sounding, but a $10 set of computer speakers produces "theater sound." Unlike a laptop there's no power hungry Intel CPU, hard drives, etc.; it consumes only 35 watts, compared to 80 watts for my laptop. Also doubles as a monitor via a 15 pin cable, but only 1024x768. Great way to play DVDs though. It'll run on clean 12.3 volts +-5%, but high voltages will burn out the flourescent tube system which lights the screen, because there's a stepup transformer for it which overheats at high voltages. So, you can get away running it on ship's 12 volts without a voltage convertor-stabilizer thingie ($150), but not while charging or running electrical equipment which introduces transients into your DC service wiring. Best is to run it on AC thru an invertor, if 35watts is in the high efficiency part of your invertor's power output curve. Only caveat is small "wide screen" HDTV flat panels are just around the corner, a normal aspect ratio flat screen TV is going to obsolesce fairly quickly. |

Indeed. Always use a 'whatever in' to 12V converter. I was involved on a ship where 12 professional LCD touchscreens were installed. They were rated for 24V and directly connected to the 24V power system (=batteries). Within a few weeks, all monitor backlights failed. They couldn't stand the voltage of a full battery (27-28V).

I was concerned about overvoltage when we got ours. The specs
indicate a range of voltages that are accepted with the max up around 15V. Since this unit is made to be installed in RVs and vans etc, it is designed to handle varying voltages during charging, etc. If my battery bank needed equilization, I'd make sure it was disconnected.

If they're spec'd to 15V, there won't be a problem. The ones I referred to were spec'd at 24V +/- 5% or so. Meindert |

I have the Happauge external USB 2.0 box and it works fine. Produces MPEG video at data rates up to 12Mbps, which is a bit better than DVD specs. It can also "data rate match" directly to DVD in three different quality levels, which is very nice if you want to burn copies of things you record with it. The internal MPEG chip in it is not as good as Vegas is as a "software only" solution but it rocks in terms of CPU overhead - like near zero during use, so you can record something while doing other things with the computer. -- -- I have used a Hauppage USB TV interface on a P3 notebook, with a USB1 port running XPPro for several years it works just fine |
