Over the last few months, I've had a number of AskSlashdot questions about quiet computers, what hardware to get, and other items for assembling a mega-machine that won't knock the roof off. I've put the finishing touches on my own mega machine -- if you're looking at doing the same thing, or are just curious about the hardware involved, you can find out about what I built.

PhysicsTom asks: "I am a Senior Physics student who's final year project is based upon using common, easily available technology to replace parts of the aparatus used in various departmental labs. Currently, my main area of interest is trying to integrate certain computer peripherals (such as scanners and digital cameras) into experiments at an earlier stage, so that images gained from the experiments (such as difraction patterns, etc) can be analysed in a program such as MathCAD straight off, rather than the much less efficient methods we're using at the moment. The problem is that I am having trouble finding out about the way in which scanners and digital cameras work, and how this would affect their accuracy with respect to what I am aiming to do." Basically, how do the various hardware aspects of such devices affect their ability to accurately measure or scan the subject of the experiment?

Lars Olsen writes: "As a complementary article to his comprehensive General Heat Transfer Guide , Dave Smith has written another great article for Amdmb.com called General Fan Performance Guide. This is an indepth guide to the performance of the fans we have in our PC's. Here's a quote: 'The specific purpose of this guide is to take the science associated with fans and translate it into a meaningful document that will allow the reader to understand how fans work and how they apply to computers. It provides a brief summary of DC power and drives. It finishes with an introduction to the concepts of sound generation and measurement.'"

synchronicity asks: "I just got a new motherboard and processor and would otherwise like to keep my system setup exactly as it is now. Every site I have visited about upgrading a motherboard and processor ends with something to the effect of 'When your machine boots up, Windows will be confused for a little bit, but will detect all your hardware as new, reboot itself a few times, and then you'll be up and running again.' All well and good, except that I don't run Windows. So what do I need to do to get my Linux (Mandrake 7.2) system to recognize the new PCI bus addresses/interrupts/etc. to make this upgrade a success?" What things do you do in preparation for such a procedure?

nettdata asks: "So I'm a 'Sun' guy who's looking to build a Linux server. I've got everything picked out except the motherboard, and I need help. I've gone through some hardware sites (Tom's, etc.) but I can't seem to find a 'top 10' list for what I need, so I was hoping some experienced people in the Slashdot forum can help me cut to the chase. This will be my home server, so I want it to be as inexpensive as possible while still being something that will perform well. (Champagne taste on a beer budget). It will be a headless box, so more than anything I want the ability to do command line boot/BIOS control via the serial port to a VT100 session like I can with my Sun boxes. (This will be done via my handy dandy PortMaster). Lights Out Management (LOM) would be an added bonus. Google, Slashdot, and ExtremeTech searches haven't turned up anything usefull. Any thoughts or sites?"

Therlin writes: "Victor Matsuda, Vice President of Sony's Entertain Robot America (makers of AIBO), sent a letter to Aibopet.com citing the Digital Mellennium Copyright Act. You can read the letter here. Aibopet is the website of an AIBO owner who enjoys researching AIBO. He also provides free software programs to improve and add features to the robots." I bet Sony won't increase their Aibo sales this way -- don't they like fanatical customers?

zootjeff writes: "I am in the process of designing and redesigning a computer for my car. This machine is based on the Shuttle FV24 motherboard. I built a box that is 8 inches by 7.5 inches by 3 inches. I also designed and built my own custom power supply. This could be useful to people who want to take linux into their car. It is also useful for solar powered battery operations." He sent some pictures, too, of what the 2nd case looks like, an overview, including (!) police report number (the 2nd revision was stolen), more on the power supply, and the third iteration.

An anonymous reader submitted "LinuxDevices.com has just published an interesting how-to article about converting a GCT-Allwell set-top box into a linux-based TV set-top MP3 player. As a helpful aside it does useful things like email and web browsing through your TV. Looks like a fun project. A related article shows how to turn the same set top box into a router."

pescatello writes "Here's a CNET story describing the disappearance of the internet appliances from the market. The latest is the AOL/Gateway/Transmeta Internet Appliance. While it won Comdex's Best in Show in 2000, it hasn't been pushed by either AOL or Gateway, and is now unavailable anywhere. " Meanwhile, my Audrey came in yesterday.

rootus-rootus asks: "I funny thought struck me as I was going over the life expectancy for tape media for backups... Since the size of 3.5" hard disks is surpassing 100GB in a reasonably inexpensive package, has anyone thought of using them as backup media, as in a jukebox or autoloader? The access times and data transfer rate for data stored on them would make backing up databases, etc. MUCH more palatable (200+GB takes a LONG time to dump to tape for a full backup) Any thoughts on the matter?" Bet you've thought about this question before, haven't you? Has anyone done anything like this? If so, how well did it work?

Chris Edwards asks: "I've been having quite a few problems with Dell support recently, and would like to ask the Slashdot community a question. To what extent should computer manufacturers support their product? I own a Dell Inspiron 7500 laptop, which has been plagued with problems since the day I purchased it. The Inspiron 7k series were the first from Dell to take advantage of the new 15"/15.4" screens that had become available. They made one very tiny mistake; they didn't change the hinges to support these gigantic LCDs. The hinges on my laptop have broken four times since I purchased it two years ago. To put this into perspective: 8% of the time that I've owned my laptop, it's been in for repair. Should Dell just replace the laptop? Their support department doesn't think so; what do you think?" Dell isn't the only guilty party here. I'm sure you all have had your share of hardware support stories, the recent Ask Slashdot on IBM Deskstars is another example of this. Which manufacturers have a real bad track record of this kind of behavior?

freebase asks: "I've been asked to come up with a way to verify SLA's relating to our inbound corporate dial-up. Before I push down the path of writing a series of shell scripts and a reverse-telnet serial driver to use an AS5200 to gather data necessary for our monthly reports, I thought I'd ask and see if anyone knows of any products/projects which can do this off the shelf. If I can find the right product, I have the money to purchase, especially if it will save me from having to completely re-invent the wheel."

krismon writes "Sony has announced that it is gonna release the Linux port(old Slashdot article) for the Playstation 2 in the US, after selling out SUPER fast in japan." I saw this running, it's pretty impressive.

man_ls asks: "I have a TVElite kit that no longer works. It was used for displaying my computer monitor on both a TV and computer at the same time. It came with an infared attachment to allow you to use the remote to control the volume on both devices at the same time, that seems to be made by EMC. Inside is an IR connector, an EMC IC, a serial connector, and an infared receiver I think. Does anyone have any more information about some 'fun' things I could do with this? (such as an IrDA for my desktop computer)"

atomic212 writes: "Sony has announced a new mid-range handheld today, the PEG-T415, a 320 by 320 monochrome model that is, according to Sony, the world's thinnest PDA. Though only .41 inches thick, it has a Jog Dial and a Memory Stick slot and includes remote control software."

Anonymous Coward writes: "Hi guys, Here is a review of the Lian Li PC626, which is a server case made entirely out of aluminium. Unex from Belgium :)" Or aluminum, which is the only proper spelling, of course. Are these cases actually worth the premium price? I may be having heat problems (for the first time) with our latest PC purchase, so I'm suddenly more interested in cooling...

nexex writes: "Tom's Hardware has a new article with a review of several KVM switches. I have considering buying a KVM switch as I seem to collect/use more & more computers, I feel left with little choice :) While I have several friends who have taken the plunge, they have all spent wildly different amounts on them. Granted price plays a great factor on the features you get, but how do you know which one is not going to end up letting you down? If you end up with el cheapo, you will most certainly end up regretting it, as this device will be carrying the signals of your primary input and output to your systems."

PyroMosh writes: "ZDNet is carrying a brief article about VIA's plans to start producing clones of the Pentium 4. VIA's already in legal trouble with Intel and it seems unlikley that this will go unchallenged by the chipmaking juggernaut. The Register is also covering this, and SiliconStrategies.com has an article with a bit more detail."

PhantomHarlock writes "VIAHardware posted a review of a great miniature PC desktop system from Shuttle, the motherboard manufacturer. It's a tiny aluminum case with a floppy bay and one 5 1/4 bay. It uses Shuttle's FV24 mobo, one of the smallest on the market. The motherboard has built in video (with S-Video out), audio, 10/100 Ethernet, USB and dual firewire ports. " Might be a nifty device to use as a stereo component with that S-Video out.

segoave asks: "It's been a while since this story was first posted. I was just curious if anyone in the slashdot community bought one of these. Does it work well? Did you have any trouble receiving it? I admit I was hesitant when I saw their SDK license agreement." It's always nice to know what others think of a product, especially before you sink hundreds of dollars into it. How well does the LinuxDA live up to its name, and would you recommend them to your friends and peers? Update: 10/18 17:00 GMT by C W : You might want to wait on this one, one of our readers has already reported problems with delivery due to what the company is calling "high order volume". The company expects to ship the units in "early November". More as we get it.
