I just got a very nice stereo receiver. If I'm understanding this correctly, it has the ability to put out at 4 ohms if need be. The manufacturer reads a certain number of watts at 4 ohms, or more watts at 8 ohms. I'm assuming that means that the receiver can drive either 4 ohm or 8 ohm speakers, is that correct?
I'm also under the impression that 4 ohm speakers are better than 8 ohm speakers. If so, why? I'm guessing 4 ohm can deliver a much more pure sound. Next, will 4 ohm speakers hurt an amp that is NOT 4 ohm capable, or will the amp hurt the speakers? From what little I could gather on this from the tons of opinions on the internet, is that if you have 4 ohm speakers, it will ultimately toast your receiver.
The stereo output is actually limited to the amount of CURRENT it can safely put out. Knowing ohms law, the mfg takes the known applied voltage and maximum current and converts this to the RESISTANCE of the speakers one should hook up. R=V/i. But let us think CURRENT in terms of i=V/R. If R is too low (voltage is fixed) then I (amps) will go too high and either open the power supply fuses or let smoke out of the wires (burn up some components)
1. I'm assuming that means that the receiver can drive either 4 ohm or 8 ohm speakers, is that correct? All things being equal, 4Ω will handle 2X as much current as 8Ω speakers.
2. I'm also under the impression that 4 ohm speakers are better than 8 ohm speakers. If so, why? Sounds better depends on other characteristics but LOUDER is BETTER (generally).
3. Next, will 4 ohm speakers hurt an amp that is NOT 4 ohm capable, or will the amp hurt the speakers?
The speakers will attempt to draw MORE current than the amp is safely capable of handling. When in doubt - follow the mfg recommended instructions. If there is a help section on the mfg website - give them a call when they are on available hours.
Video camera storage/orientation question
I have a 2003 Panasonic DVX-100A (3 CCD digital camera) in a Pelican case. I have cut out the Pelican foam so the camera fits snugly in a space and can't move in any direction. For reasons not worth getting into, I would like to rotate the orientation of the interior Pelican foam, so when the case is in the carrying/upright position, the camera will (now) be upside down. But when opening/storing/some transport it will be oriented on its side.
Is there anything wrong with this, having a (or this) digital video camera spend parts of it's time upside down? Otherwise I will have to buy new foam and redo cutting open the spaces for the camera and peripherals.
I finally figured out that as long as the camera has adequate foam on all 6 sides for cushioning/impact protection, orientation should be irrelevent. Depending on the foam density, you will want a minimum of 1" on all 6 sides when the case is closed. You also don't want the foam to be compressed much when the camera is stored. The foam needs to be able to absorb the impact energy; something it can't do if it's already compressed near its limit. I little compression when stored is fine (and somewhat desirable) so that the foam can "suspend" the camera in it's place.

K-Cup/Pod coffee makers for coffee snobs?
I guess I'm what some people would refer to as a "coffee snob" (although, I know there are a lot of people who are a lot more snobby than I am).
I go out for coffee twice a day, and I can literally open my front door and throw a rock at 4 or 5 places that sell really good coffee (Blue Bottle, Stumptown, Counter Culture, intelligentsia, etc.)
But, I'm going to be moving to a place where that isn't possible anymore.
I live alone, and like 2 cups a day,
I'd rather not be making pots of coffee at a time, so I was thinking about getting one of the k-cup/pod machines.
Will I be happy? Are there pods with really good coffee? how about pretty good coffee?
Also, I know they make pods that you can fill yourself, but I've heard not so great things about them.
Any suggestions for machines and or pods?
Cool lighting video (not instructional)
Thought you guys would enjoy. It's a video showing the effect that different light positions and hues have on a person's face.
