When you look inside any mid to high end amplifier, you typically see one large coil, even if it's a stereo or surround-sound amplifier. What's the deal with that? What does that coil do and why doesn't the amplifier need one for each channel?

Without seeing an actual schematic I'm only guessing, but it most likely is involved with voltage regulation in the power supply section of the unit.

the large coil usualy is the "ring kern transformator"

don't know the english term for that.

its like the regular ac/ac converters, just that the two coils aren't separate, but on top of each other - thats more efficient.

you don't want switching power supplies - since that introduces noise.

So, if I see "one big coil" it's actually just $NUM_CHANNELS smaller coils stacked up on top of each other? That would seem to make more sense.

Depends. If the coil/combo is in the power supply it might be $NUM_AMPLIFIERS instead of $NUM_CHANNELS.

Dear lazyweb:

There is now a television in the Mouse House that supposedly supports DLNA.

What's the best DLNA server for Linux (native or cross-platform, doesn't matter)

Non open source solutions need not apply.

Try http://minidlna.sourceforge.net/ Seems rather lightweight and is very easy to set up.

I tried it on an LG bluray player only, most movies work fine. Sometimes a movie does not run, but these are sometimes old and odd avi containers which had issues on real PCs too.

Audio is odd, I can browse all my soundfiles by category, title, etc, but no music plays, ever... I do not care much since it is broadcasted via mpd and mt-daapd too, so most of the time, one of my devices plays what I want.

the most recent logitech squeezebox server can do DLNA; however its focused on audio, so mp3's will most probably work, while movies may not ;-) YMMV

MiniDLNA looks like the answer. Thank you the_mgt for the suggestion. It installed easily from the Debian repository (the open source world invented the "app store" of course), configured easily, and my "Smart TV" found it without having to configure anything on the client side.

My home videos (all digital since 2006) look fantastic on the new screen.
The camera's onboard analog-out always made the picture look pretty lousy, which makes sense, they probably used the cheapest components they could find for that.

And yes, I'm that cheap, it really did take until 2013 for us to finally buy our first HDTV.

Don't feel bad about that. I didn't buy *my* first HDTV until not quite two years ago (early JAN 2012). Every time I went to buy one, I ended up saying "let's wait six months - the TVs will be better for the same price." I was right. Then the old TV finally "up and died" and it was no longer a "wait" option.

Same here, maybe 1,5 years now. We were "forced" to accept a flatscreen as a gift. Next move is to replace all your analog input devices because the picture will suck big time compared to hdmi... still need my non-hdmi dvd player because it is region-free, the bluray player only plays regional dvds. :(

I am also still not willing to replace my pre-hdmi av receiver, though. I would want to upgrade the price class, meaning I would have to update the speakers and buy an active subwoofer... all the time hoping that my son does not want to suddenly "repair" the speakers with some sharp object. Sir, no, sir!

BTW, IG, you want to use component cable for the Wii, but I guess in america you are already using that. Picture was still better with RGB/Scart cable on the analog bulky old tv set. But for some reason, the RGB version is only interlaced, which gives significant flicker on games like Animal Crossing.

In the US the Wii ships with a composite video cable (one RCA connector for video, and two more for stereo sound) and therre is a component cable available from Nintendo as well. There are all sorts of aftermarket products, including one called "Wii2HDMI" which appears to be just what it sounds like.

From what I can tell by reading, the component cables bring you to 480p instead of 480i, but you don't get any additional resolution. (Yes I know component renders the same resolution better)

Gotta stick with what I've got for now. It turns out this TV only has one set of non-HDMI inputs for composite "or" component, so I'm sticking with the composite switcher built into my home theater amp for the time being.

The benefit is less flickering. When running through the game horizontally in Animal Crossing, I got an amount of flicker that was just not bearable. You could see the upper and lower part of the image updating separately. I guess Mad World and Blob or other fast moving games would be unplayable without tremendous amount of headache. Could just have been due to crappyness of my TV set, though.

That sucks. It also sucks that you have to switch out all cables and amps, etc, after buying a new TV. Been there myself, ranted here about that more than once. Falling in love with a Marantz SR 8005, but I first need to get a new satellite receiver, ours is crappy.

What doesn't suck is that the YouTube player in my TV can be remote controlled by the YouTube app on my phone. It *so* beats trying to sharpshoot the letters on the on-screen keyboard.

It's time to fit out the lower level of my house for some fun activities.
One of the things I want to do is hang a video projector from the ceiling to turn en entire wall into a screen. It will be used primarily for video games, but we also want to use it to display the occasional video of Anita Sarkeesian being forced to wear a hijab. The room is not terribly bright so it should be a good space for a projector.

Anyone with projector experience have anything to suggest? Any particular brands, technologies, deployment strategies, etc to pursue or avoid?

"Not terribly bright" is way too bright.
The absolute best result with any projector, from passably consumer grade to high end, is ***theater*** darkness.

Anything else will seriously degrade the result.

Yes, if we want "theater dark" we'll turn the lights off.  :/

The rest of the time we're going to use it for video games.  I'm hoping to find a Nintendo title that has Princess Peach and Princess Daisy beating the crap out of Anita Sarkeesian, but the violent games tend to be on Xbox, and I will not buy Microsoft products...

So the projector I've got my eye on right now is an Epson PowerLite home Cinema 2000.  It's a mid-tier projector with native 1080p resolution and 1800 lumens.  Seems like it's right about on the part of the price/quality curve that I want to be (not crap but not breaking the bank either).  Full 1920x1080 is of course a requirement.  I was planning on a ceiling mount but now I'm also considering building a box on the opposite wall.

That epson is, quite simply, substandard. You will *not* be happy with it and within one week, if not sooner, will intensely regret the purchase. Within a month you will straight up hate it.

Reason?
Only 1,800 lumens color brightness; only 1,800 lumens white brightness.

For movies and gaming that is an ***absolute*** deal killer, period.
You get what you pay for, and will be planning its replacement the day you get it home.

Recommendation
OPTOMA HD141X
3,000 lumens.
Supports every conceivable video mode in use today, including 3D.
Cost: $600.00 +/-


There are others.

What I recommend you do is go to the nearest Best Buy. Purchase the best projector they have that falls within your budget. Take it home. Try it out for a week. If you don't like it, bring it back. Best Buy has one of the smoothest and most pain-free "no questions asked" return policy among all of the "big box" thieves.

And once you find the unit you truly like, return it.
Then find the same unit online - you'll pay about 10 to 20 percent less.

I've never heard of Optoma. Are they any good?
