    FREE Radeon 9600 128MB AGP Passively Cooled (2)

    Yeah, that's exactly what I was looking for. I'll PM you with my address. Let me know what the shipping will be (I assume these would fit in a small Priority Mail flat rate box unless you prefer to ship them some other way).

    FREE Radeon 9600 128MB AGP Passively Cooled (2)

    Are these AGP 8x? If so, I would be interested.

    Desktop pc freezes when using either Win XP or Win 7 OSs

    I second time's recommendation to run Memtest. I ran it for a few days after I replaced the caps in my motherboard just to make sure everything was OK. Bad RAM could most definitely be causing these random freezes.

    Desktop pc freezes when using either Win XP or Win 7 OSs

    While we're on that subject, I only spent the amount of time I did because I was reasonably sure the caps were the problem. If the problem could have had many potential causes, I highly doubt I would have bothered. BTW, about 2 months ago I replaced the remainder of the caps when the...

    Desktop pc freezes when using either Win XP or Win 7 OSs

    Another suggestion here-try removing the TV card as time suggested earlier and see if you still get freezes. If not, that's your problem right there. Even if the software isn't installed for it in Win7, the card might still be interacting with your system in ways which make it unstable.

    Desktop pc freezes when using either Win XP or Win 7 OSs

    In case it is only the MB, a cheaper route might be to look for used motherboards which support your processor on eBay, or perhaps some of the members here have a spare MB of similar vintage which they would be willing to sell. If you're going to buy a brand new motherboard, might as well spend...

    Blood pressure

    One more thing-BP rises if you're ill. I've had a mild case of the flu for the last few weeks which accounts for my higher than normal readings.

    Blood pressure

    Try to get an average of many readings before anything. My BP can be all over the place, so I don't put much stock in any one reading. Just now it was 152/92. A few days ago it was 133/80. I've seen it as low as 90/60. A lot depends upon what I eat, how much I drink, how much I exercise...

    Cycling

    Reminds my of my days cycling on the country roads around Princeton when I was in college. Not much advice to give you on cleaning the bike other than to be thorough, especially regarding the drivetrain. Mud seems to work itself into literally everything. :(

    Computer-related stuff you bought in 2011.

    $94.99 for 16 GB of RAM my next upgrade, about $15 in parts to repair my A7N8X-E, and $70 for a second hand laptop. That was it for me in 2011. Normally I'll spend a few hundred at least.

    Cycling

    I love tailwinds. I once hit 65 mph in a descent with a tailwind to assist me. As you say, pretty intense, but in this case I only momentarily touched 65 mph, then quickly slowed as the hill leveled off. So far, the highest I've pushed my Airborne to has been 36 mph, but winter clothing and...

    Bicycle LED headlight

    That would be full cycle every day which would be great. I don't ride quite that much, although when the weather cooperates I might get in 30-35 hours of riding in a good month. One thing I'll be doing on my end is testing the durability of the entire mounting system. The roads here resemble a...

    An LED lighting project

    Maybe. I think Deal Extreme has 120VAC drivers small enough to fit in that. Like everything else from them though the quality is a crapshoot.

    Bicycle LED headlight

    Thanks Dave. That actually sounds pretty good, especially the part about selling the team on the lights. I sent his engineer an email a few days ago on what I had in mind but he hasn't gotten back to me yet. I'll start working on the preproduction prototypes for you and me. Before we even...

    An LED lighting project

    I don't think anybody makes a 120 VAC LED ballast that small which is dimmable with a regular triac dimmer. I'm not even sure if it's possible. If I find out differently, I'll let you know. The best way to have a small, dimmable light source off 120 VAC would be to use a wall wart (12V, 1 amp...

    Bicycle LED headlight

    To make a long story short, a friend of mine whom I do quite a bit of work for is interested in my concept for possible production (we'll need to see if the numbers work). In the end this will mean a better product than I can make alone but of course a longer wait (for the final version...

    Cycling

    2K feet in 15 miles is around 2.5%-shallow enough not to be obvious that you're climbing, but steep enough to slow you off your "flat" pace by quite a bit. Winds can have the same effect as hills. Yesterday riding out of the city I was getting into the high 20s quite a bit on roads which were...

    The destruction of liberty

    Extradition to the US is fine if the person is a committing or plans to commit crimes which cause injury or death to US citizens. What we're talking about here is at best financial loss, and even that part is debatable. The majority of people who download stuff illegally aren't people who...

    How to deal with wind chill?

    Incidentally, the time I felt the coldest in my life was one day in February 2007 when I went to Chinatown for Chinese New Year with my mom. It was about 15°F when we left that afternoon. By the time we came home late that night, it was single digits. To make things worse, when we got off the...

    How to deal with wind chill?

    Don't know whether this belongs here or in the cycling thread, but I did an hour on the Airborne yesterday when it was hovering right around freezing. Today it was 23°F when I went out but I still lasted 6 miles and 23 minutes. In both cases I only stopped riding when my fingers were numb to...

    Thanks for sharing. Sounds like an epic ride. What sort of data did you need to upload to the site, and would I be able to do the same (I have Garmin .gdb files of my rides)? Nice ride earlier today. 24 miles on the Airborne, about 4 miles past city limits and back, in 1:31. Nice tailwind...

    RIP FIC AU13

    This thread may be of interest. If you see bulging caps and are handy with a soldering iron, you can probably effect a repair yourself for under $15 (plus some of your time). Other than that, I agree with Coug. It's just not worth investing large amounts of cash in otherwise obsolete...

    Cycling

    I rode my Airborne this past Saturday and Sunday in 36° to 38° F temps, 42 miles in total, both rides averaging in the high 15s. If you're not already wearing them, gloves are a must for any riding when it's much under about 45°F. Even with that, my tolerance for riding in this kind of weather...

    Synchronizing to an NTP server over LAN

    /setsntp: wasn't even a valid switch in Vista for w32tm. Before I even started this thread, I did try net time /setsntp: which worked just fine for setting the NTP server ( so does w32tm /config /syncfromflags:MANUAL /manualpeerlist:time_server_name /update ), but w32 time refused to synchonize...

    Synchronizing to an NTP server over LAN

    I recently set up my desktop PC as an NTP server ( don't ask-it's a really long story ). Everything works well, time seems to match my G-Shock solar atomic watch exactly. I even set up my laptop to synchronize to the desktop over the LAN every 15 minutes. I used task scheduler to run the net...

    How to deal with wind chill?

    Layers works for me. If it's really cold, I need a nylon windbreaker somewhere among the layers. We're actually finally getting into good cycling weather around here (by my standards, anyway), so long at it stays above about 35°F.

    Shaving solutions, or, what do Gilette and all those companies do with all their $?

    In the case of humans that might make sense if hairiness was universal. It isn't. Some adults have little or nothing in the way of pubic hair or body hair. My own preference is hair on the head and eyebrows, only. The second I see hair anywhere else, it's a huge turnoff. I've actually known...

    Something Random

    Thanks guys for the birthday wishes! And thanks CityK for the birthday gift! The #7 train in the beginning, and the shot of Queensboro Plaza 50 seconds in, is definitely on my list of NYC experiences-I've ridden that line literally hundreds of times, if not more. Really, anything subway is...

    Ouch. :-o I'm going to hazard a guess that you either had an accident doing stuff around the house, or riding your bike. I'll let you know either way as soon as I make an attempt at it. A nice custom-machined enclosure would be nice. Heck, if we end up going that route, might as well...

    Bicycle LED headlight

    I was pretty sick for much of the last few weeks, so things haven't progressed as rapidly as I thought they would. Don't forget also I'm basically designing this from scratch. If I was just copying an already built and proven design, it might have been done already. Just to update you, I've...

    Llano for HTPC?

    I was (maybe still am) seriously considering either Llano or the next generation APU for my next system. The reason is I anticipate eventually needing more graphics capability than either most onboard, or Intel's integrated graphics, provide but I don't want to buy a discrete graphics card. I...

    New motherboard supports 288GB of RAM

    The shock, the horror!

    They most definitely did. One of my grandfathers had an AMD VTCPU-01 1-bit vacuum tube processor running at 3 KHz with 12 bits of relay-based RAM. This was considered state of the art for the time. :rofl:

    Large-scale water cooling (heat transfer)

    The goal of this project seems to be to recover the heat from machines which will be running regardless. Obviously if heating is your only goal it's easiest to just use a conventional heating set up. Incidentally, the one PC I have on in my bedroom 24/7 seems to make that room about 5°F warmer...

    Large-scale water cooling (heat transfer)

    These are about as simple as you can get. I'm actually using something similar on the water block of my thermoelectric temperature chamber as a failsafe in case water flow is cut off. Mine came with some surplus TEC assemblies I bought.

    Norelco 7345XL for me. I shave every day because I find stubble annoying. When I used to use a blade my face was always irritated, especially my neck. When I was in college I started using electrics. Big difference. Maybe they don't shave quite as close as a blade, but the advantages make...

    Large-scale water cooling (heat transfer)

    This isn't a bad idea and I'm wondering if it could be taken a few steps further. I'm thinking along the lines of a hot water heating system for the entire house where the water is preheated first by low-level waste heat from various appliances ( computers, refrigerators, LED lighting ) before...

    Christmas 2011 PC for Wife

    From my reading, one of the strengths of Llano is the integrated graphics are good enough to tolerably play many games, 2-3 times better than iCore, and better than just about all integrated motherboard graphics. Downsides are the regular computing performance and to some extent the price...

    Poll: How much data do you take care of?

    Unique data for me is what's on my hard drive. I have a combination of pictures I've taken, documents (Excel, MSWord), PC board CAD files, downloaded files of all sorts (images, news articles, data sheets, trainsim stuff, etc.), and my OS/apps. It still fits on my 200 GB boot drive, barely...

    Idea: Mounting Rail for Bicycle Stem

    I'm putting the battery box and light engine together for my light because I don't want to run extra wires. Do you prefer that option for yourself also, or would you prefer the battery box to be separate (in which case you could put it in one of your water bottle cages)? The battery box needs...

    Idea: Mounting Rail for Bicycle Stem

    That is a nice idea. My handlebars always get crowded with all the junk I mount on them. The stem seems a natural place to put stuff. I've yet to see anything exactly like you suggest. Seriously, I think the idea might be patentable. It's certainly marketable. The closest thing I've seen...

    Bicycle LED headlight

    Yeah, they're all in series so if one goes open the string won't light. That's not really a concern though because LEDs almost never fail open circuit, and these aren't being overdriven. XP-Gs are speced for 1.5 amps. I'm only driving them at 1 amp tops. Most of the time it will be way less...

    Bicycle LED headlight

    I would just put enough LEDs in series to come fairly close to the minimum operating voltage of the battery back (in this case about 10 volts so I would use 4 red LEDs in series), and then have a linear current regulator to absorb the remainder of the voltage difference. Another option is to...

    Bicycle LED headlight

    Not hard at all. I've actually been running a similar setup on the Raleigh where I have a plug/wire to draw power from the headlight batteries for the taillight. It saves me the bother of messing with batteries for the taillight.

    Cycling

    Yeah, that's kind of like the difference between my Raleigh and the Airborne. Unfortunately, I've yet to take the Airborne on a decent ride because it lacks a headlight. I ordered the batteries today, and this made my life worlds easier. I don't have to spend time designing a protection...

    question PC may have died-need some feedback on MB/CPU/RAM

    I've been designing and repairing electronics for over 25 years. To me my PC was just another broken piece of electronic equipment which could potentially be repaired. I hate discarding things which still have some useful life in them. That made attempting repair second nature. Now if this...

    question PC may have died-need some feedback on MB/CPU/RAM

    That's exactly the reason. In the scheme of things, spending an extra $50 on my next upgrade won't break the bank. I'm also interested in future-proofing any upgrade as much as possible since I tend to use systems for a long time in between upgrades. 16GB may seem outlandish now, but I might...

    Annoyance of the day - ATM charge for usage

    I'm strictly cash in brick-and-mortar stores except for large purchases (and I put those on credit card). The big problem for me with debit cards is keeping track of how much you have left in the account. My debit card draws on my checking account. Generally, I only put enough in there to...

    question PC may have died-need some feedback on MB/CPU/RAM

    For what it's worth, the time value of my money at this point is under 2%. Assuming I went with 16GB and spent $100 now, if it's selling for over $102 in 6 months I'm ahead. And there's a very good chance I might be upgrading in less than 6 months anyway. The graph looks like it bottomed out...
