Not a chance, Doug. The basic combustion cycle from which an engine derives power produces CO2 in direct proportion to the amount of fuel consumed. The other emissions which the US controls are byproducts of the basic combustion cycle, which if perfectly "clean" would only produce CO2 and...

At least the color temp will be nicer than incandescent, for the second or so that it burns anyway. :mrgrn:

I'm not tired of seeing climate change threads, but I'm tired of government officials who pretend that it's all junk science. It seems that maybe the changes aren't getting the attention they deserve because they seem to be affecting the southern hemisphere a lot more than the northern one...

Nothing with any decent output yet but those small-base lamps will definitely be among the first to offer LED replacements since they're the most inefficient of all common household incandescent lamps. The 40 watt ones only put out about 450 lumens. We can do this with LEDs today using about...

How are those in the noise department? One reason I'm sold on Seasonic is their very low noise level. Despite the low noise, the 120mm fans they use manage to move enough air that I was able to dispense with case fans without any problems.

Playing around a bit more I found that 100% of my problems were related to the graphics card driver (I suspect this is why Merc finds so many issues with nvidia cards). The most recent version of the Win9x drivers caused the crashes which trashed the IRQ tables, and I wasn't able to play 3D...

Most of what they say is true for the current state of LED technology. However, let's look at what happens as things get better: LEDs have already been lab-tested at HID efficiencies. It's only a matter of time before such LEDs are commecially available. Cree and several others claim that...

More random thoughts-I just noticed that we had a total of 77777 posts on this site as of 7:04AM EST today. Lucky 7's anybody? And Tannin had the honors of making the lucky 77777th post.

To update everyone on what may have caused the problem in the first place, see the last post here. Now remember when I mentioned that my problems first started when I went to the overlay setup tab for the Hercules card. The system crashed, and that basically screwed up everything, including...

Success at last! :mrgrn: I enabled ACPI, added the line ACPIOption=1 in my registry, and followed the remaining steps in that article I linked to a few posts back. The system detected the ACPI BIOS, and went through several reboots installing the needed drivers. Upon one reboot I noticed...

No, it's not sharing the IRQ with the AGP slot. As I said, I had this problem even with no cards. You're right, but I want to make sure the motherboard has no issues before I do. Right now I tried a few known good PCI graphics adaptors and the system wouldn't even POST whereas before it did...

I didn't have any PCI cards in at all when I noticed the problem, just the AGP graphics adaptor. I added my Promise controller to slot 3, it detected just fine, and everything else was otherwise the same. All the integrated peripherals work just fine. The problem is the graphics card. I'm...

Well, I managed to install Win 98 with the setup /p i switches (which disables ACPI) mentioned in that article and system information tells me I have no problem devices. However, the video problem still exists. Looking in device manager-pci bus it said IRQ steering disabled, IRQ table errors...

Searching a bit, I found this. Most relevant to my problem is the following: Emphasis mine. That's exactly what my system is doing. In fact, the problems seemed to start once I installed the motherboard drivers for the USB ports now that I think about it. The article also confirms what...

That's one of the things which turned my off to a lot of volunteer work. I love helping people making an honest effort to better themselves. I used to help my friends study for tests all the time in high school. One girl I helped even managed to get a seemingly impossible 100% on a test with...

Playing around some more I found that the graphics card gives all the high color VESA modes in DOS just fine. Obviously nothing wrong with it then. As I said in my previous post '98 is the problem. Yes, I'm taking everyone's suggestion about forgetting '98 on this machine. Understating it a...

Thank you for answering my next question before I asked it. :thumbright: Yes, I did see ACPI enable/disable in the BIOS and left it at the default (enabled). That probably caused my problems since I'm guessing Win98 doesn't know how to deal with ACPI. In any case I did a fresh install of '98...

Wow, thanks a million Tony! :thumbleft: I'm going to get little sleep and take a break, but I'll post later how it went. Glad to hear the motherboard is probably still OK, just a little confused. It sure sounds like you've spent your share of time dealing with this exact same problem. BTW...

As some of you may know some time back Merc sent me an A7N8X-E motherboard and XP2500 processor. Last week I bought some RAM for it, and on Tuesday a nice Lian Li PC-60 case arrived. I assembled everything, put in a spare floppy, CD-ROM drive, and 40 GB Maxtor, and then installed Windows 98...

Shouldn't be a problem since each spot would only be dissipating about 3 to 3.5 watts. Not really, but maybe you can adapt mounts for MR-16 halogen bulbs. In fact, eBay has premade LED arrays designed as drop in replacement for MR16 halogens. I believe they're also designed to run off 12V...

OK, now I understand a little better. 1000 watts to light a few 18"x18" cases really seemed like a lot. Now I know it was also for general lighting of the booth area. Anyway, to light an 18"x18" case to 1/10 the equivalent of full sunlight requires a light level of 5000 lux or 500 lumens per...

If you have 1000 watts of halogen bulbs then that's roughly 15,000 to 20,000 lumens. I could be more exact if I knew the specific bulbs. In any case, you're looking at 300 to 500 watts worth of LEDs to replace that. Forget the 5mm and 10mm ones. Granted, right now they're more efficient than...

The problem is right now LED efficiency isn't high enough to appreciably reduce your power consumption. Maybe with LEDs you could get by with 500 watts worth since they are roughly twice as efficient as incandescent lamps, and you'll need a huge heatsink to mount them on. Even with T-8...

Better to be honest than to lie in order to attract someone. Sooner or later the person will discover the real you anyway, and be mad at you for lying to them. That's not a good way to start a relationship or even a friendship. BTW, if this part of your profile is true Merc the future looks...

That sounds about right. Just be aware that those maximum ratings are misleading since they are usually a one time deal. A 4200 joule rating means it will indeed protect you from a 4200 joule surge-once. After that the surge protector is usually destroyed. However, such large surges are...

Probably the absolute best cells are Sanyos but they are a bit pricey. A lot of people swear by them. They're usually pricey but someone on eBay has some fairly cheap here and someone else has another auction here. In the past all Energizer rechargeables were just rebranded Sanyos but I heard...

I'm actually busy checking out RAM right now so if Coug gets the other DIMM working Tim could probably use it more than me. Best price I've found for 1GB PC3200 so far is $68.49. If anyone knows of any better prices please let me know soon since I'm about ready to order. Note that I need...

First there was the hype, and then I saw idiots camping out Tuesday night waiting for the stores to open. Finally, everything else paled by comparison when I checked eBay. $12,100 for a game console!? :o And I saw quite a few other auctions which closed in excess of $5,000. If this...

I agree 100%. I first saw those on Newegg. My first impression was that they reminded me of the squirrel cage blower housing on an HVAC system. Yes, it's different, and awful at the same time. :eekers: :frowner: Thank goodness for the high price or they would probably be the latest trendy...

For those who might be buying some things on eBay this month, there are a few holiday coupons: $5 off of $50, code: C2-Holiday2005 $15 off of $100, code: C3-Holiday2005 10% off ($25 max savings), code: C1-Holiday2005 I don't know the expiration dates, but the C1 code worked for me. Enjoy!

I read that on CPF although I'll take it with a grain of salt until I can actually buy the LEDs. Still, it's an interesting development for two reasons. One is of course the increased efficiency, and the other is that they're converting purple light to white without a phosphor (that should...

It's not just the low noise level which is great about Seasonics, but also the efficiency. Mine gets close to 80% according to the silentpc reviews. The latest ones get close to 90! Don't be surprised if in a few years they reach something like 97% or 98% efficiency. That could mean they...

Meow. ^^ :cat: BTW, yes, the Seasonic are in a league of their own. I've been using a Tornado Super Silencer with active PFC for the last 2 years. Very quiet, very stable, and a claimed 0.99 PF.

To explain PFC in more detail, as you may know the power used by our PCs starts off as 120VAC, 60Hz. 120VAC is a sine wave with 60 cycles per second and a RMS (root-mean square) voltage of 120. Now the interesting part. If you've ever had introductory courses to electrical engineering I'm...

I replaced the battery in my APC 650 a few months ago. The original was 11Ah and the new one was 12Ah. In general you have to get the same voltage when replacing a battery so 2 12V in series won't work if the old battery was 12V. You can get a different capacity, usually larger, with no...

That complicates things a bit if you're sending the signal to several places because the load is higher, and could drag down the voltage. That may cause problems, but then again it probably won't. Without knowing the specifics of your system, the only answer is to try it and see what happens...

I assume you mean a low level audio signal. Given that it's low frequency (<20KHz) a pair of wires should do, or better yet a small coax so you don't pick up any interference. I don't think the signal will suffer any audible distortion going only 150 feet. No need to convert to digital and...

Games are almost a non-issue for me. The only ones I play are MS Train Simulator (which uses Direct X), Flight Simulator, and Fly!. Now one thing I might have a problem with is that my CAD PCB tools are still DOS-based. They were purchased over 10 years ago, and aren't used frequently enough...

Well, on the plus side is that my OS and most of my apps (except Train Simulator and Flight Simulator) are on my 4 GB boot partition. I have a 2GB partition used solely for temp files, internet cache, swap file (which is never used anyway). Therefore, it's fairly easy to copy my entire boot...

Yes Tim, I'm still running Win98 but I'll probably be switching to either Windows 2000 or 2003 in the not too distant future. I just want to make sure I can keep most of my installed programs and menu items with an OS upgrade rather than having to start from scratch again.

Welcome aboard, HMTK! I think you'll find this place is a little more civilized than SR, and also with more diversity of opinion.

Yes, exactly, and I admit I'm as guilty as anyone. I just haven't felt like investing the time yet to learn Linux, and also some of the apps I use probably don't have Linux equivalents. Windows may make things quicker or easier for most people when it's working, but that line of thought...

Offering money in return for something done as a favor is often a way of distancing yourself from the person who did you a favor. Instead of thinking of the person as a friend who did something for you gratis, they just become another person you had a business transaction with. Feeling...

I send my condolences Merc for whatever they're worth. I just can't understand how a person could change so drastically as your ex, especially someone in their late 20s. I hate to say this but if she were my ex I think I would put a contract out on her. :diablo: As it is I feel like doing...

It depends upon what you listen to. Some kinds of talk radio can get you really agitated, for example. As for music, a lot of the pop music commonly played on the radio gets you hyper, and it shows in the way people drive. In fact, thinking about it there's really not much I can think of on...

And that's the understatement of the century. NYC is automotive anarchy, for lack of a better description. Here's a short list of what I see on a daily basis: 1. Running red lights. Not right after they turn red, but just going through a light which was red for 20 seconds already like it...

And do you know the reasons for this trend? Your observation is dead on. It started in the late 70s and early 80s, and it's gotten steadily worse. Not surprisingly, it coincides exactly with the time the 55 mph national speed limit, arguably the dumbest thing Congress ever did, was in effect...

I thought this essay on mindset by locomotive engineer Al Krug (also look at the rest of his very excellent site) is relevant to this discussion. Basically, getting into any mindset and doing things by force of habit can lead to disaster. Same with cell phone use, running red lights, etc...

Interesting topic, and a big part of the problem as I see it isn't cell phone use or any other distraction, but rather not having the proper judgment of when you need to concentrate 100% on the driving task. Take city driving, for example. This is the kind I'm most familiar with, or rather...

Or were the platters doing a 360 like Linda Blair's head in the Exorcist? :o Wait a minute, they're supposed to do that. :D
