I am looking for a resource, preferably web based, that will give me release dates for new electronics and software. I have been able to find websites that give that information for Books, CD's and DVD's but nothing for software and electronics.

I'm in a band. Two guitars, bass, drums. We're looking at maybe throwing in touches of synth -- touches of atmosphere, maybe an occaisional lead line. I have a keyboard/controller (an M-Audio Oxygen8), so I'm just looking for advice vis-a-vis a cheap-but-usable synth module. [more inside]

Over the past several years, I have been burned by poor quality in home electronics from various manufacturers. I have purchased pieces by Sony (home stereo), Panasonic (theatre-in-a-box) and RCA (various pieces of junk), and all have given out in one way or another far too quickly for my liking. In a renewed attempt to build a proper home theatre system (DVD/CD, receiver, speakers, etc), and recognizing that I haven't the money for really high-end stuff but will avoid anything cheap, I seek outside opinions as to which manufacturers are making products that are of reasonable quality, and reasonably priced. Your experiences, please.

I just purchased a Mitsubishi WD-52525 DLP HDTV and the manual suggest that some problems might occur if a surge protector and AC line conditioner are not used. Any recommendations on satisfactory surge protectors and line conditioners (something in the mid-price range)? Also, could someone explain how a line conditioner works and why it is necessary?

DVD Troubles: For Christmas I received a DVD box set of an 80's tv miniseries that I loved as a young teenager. The second and third two-sided DVDs showed as "bad" in my DVD player. With much sadness, I packed it up and returned the item to Amazon, requesting an exchange.
Today I received the replacement set. I eagerly popped the second DVD into the DVD player so I could finish my miniseries marathon. But it is yet again showing as "bad." I tried this DVD in two players (one cheap, one midlevel), both with the same result. There are no hairs, scratches, fingerprints, or dust. So what is going on, and what should I do?

My car CD player (a Sony unit, probably about 6 years old) pretty much stutters/skips every CD I put in it, usually 5-10 minutes into the disk. Should I replace it, or try those lens cleaner thingies? Also, if I go to replace it, what's the metric in CD players' model specs that will tell me how well the lens will handle light scratches and/or burned CDs? I guess I could just get a really expensive one, but the only feature I really care about is that it doesn't skip.

My parents recently gave me $400 as a present, with the express condition that I use it to buy something (which means I can't save or invest it). Originally, they were going to get me an iPod, but I already have one. I'm thinking about a digital camera, so my question is: Does anyone have any suggestions for a good camera, or perhaps some other neat electronic gadget, in this price range?

When I got home from work yesterday, my computer speakers were making an incredibly
horrible noise. When I unplugged them, the transformer was hot to the touch. There were storms in the area yesterday, although the surge protector plugged into the same outlet wasn't tripped and nothing else in the house seems to have been damaged. (The speakers were plugged directly into the wall, not the surge protector, because I had run out of room.)
So my question: would it be dangerous to plug them back in tonight and see if they're a lost cause? Should I just buy some new speakers and be done with it? (The speakers were expensive, but about 6 years old.)

I recall an application for the Treo 600 phone which allowed me to dump pictures from my phone directly to my Mac bypassing the built in route which only allows you to transfer images by emailing them. I think I saw it on Gizmodo or Boing Boing a while back, but can't find it now when I search. Anyone know what the name of this Palm application is?

How do microchips work?
I understand it at a very basic level. I know that when you apply current to a semiconductor, it becomes conductive, and that this closes the gate in a transistor. By opening or closing the right gates, you're able to do basic counting and logical operations.
Here though, my conceptual model totally falls apart. Because try as I might, I can't get my head around exactly what it is that controls the current going to the semiconductor in the gate in the first place. How does the microprocessor know to open or close a particular gate? It seems like if it already knew to open or close a gate, then the operation has already been done. It's like you'd need another microprocessor controlling the current within the first microprocessor, and so an and so on back to some omniscient prime mover.
