perfect finish for my guitar?

Hello, i have a 1995 Kramer guitar and i just sanded the old finish completely off, then painted it with Ace brand indoor - outdoor fast drying enamel spray paint. (i sprayed it in the cap and brushed it on). When i did it i used the colors red, black, and white because i did a replica of Eddie Van Halen's classic guitar. I wanted to put some kind of protective finish over it so the paint won't ware off or fade. Can someone tell me what would be the best protective coat that i could put over the finish? (it needs to be waterproof because i sweat a lot when i play). thanks.

Nitrocellulose is the most common used high end finish that you put on guitars. You can also put lacquer or polyurethane on it. Nitrocellulose lets the wood in the guitar breath a little. You can research the three finishes online to make your choice. The best way to put the finish on is to spray it on.
After putting it on, you may want to buff it out to get a mirrored finish. If so, you should use sandpaper starting at around 1500 grits all the way up to 3000 and use a wet sand. Then get some high grade micro abrasive polish to really make it shine. I don't know how involved you want to get, but you can look at numerous videos on youtube to see how its done or check with Stew Mac (link below) for proper parts and techniques for a professional finish.

Is there a program to increase the volume out of my laptop speakers?

I have an old Sony Vaio and the DVD volume is not great. Is there any way to boost it up?
The internal volume controls are all on full.

What you can do install applications or media players with a built in volume boost or equiliser setttings ,such as winamp,or VLC media plaer(www.videolan.org).
In VLC media player as your playing the file,press Ctrl+Up arrow key to increase the volume to upto 400% of the original.
in winamp,go to EQ settings,switch it on and increase all bars to high including the very first one with the +12db ,-12db writings.
This will seriously improve Your DVD enjoyability.
(Not too sure of Winamps DVD capabilities,but VLC supports DVD).
But in general if the DVD player you have has EQ settings the use that itself to do what i suggested.
Blaze DVD player(http://www.blazevideo.com/) has a built-in vlume boost as well.

Engineering Effort of Hp on Dat160

 

The majority of the engineering effort on the DAT-160 drive has gone into the

DAT 160 cartridge load/unload, DAT160 media threading and tape path. The

base error rate ERT of the drive measures how good the tape path and threading

is. Minor deviations in tape tracking and tape edge damage manifest themselves

in a degradation of ERT.

 

A key design brief of the DAT160 tape drive is that it is a transition step to higher capacity DAT technology and HP wanted to ensure that the installed base had a good backwards compatibility experience. Ensuring existing users of DAT72 and DAT40 media see a good return on their investment in the technology is seen as being crucial to the ongoing success of DAT. HP sees backwards compatibility as being a fundamental element of the DAT160’s return on investment equation, unlike other technologies that offer increased capacity/performance but offer no backwards compatibility.

 

A significant element of any development program is testing. Design Verification and Test (DVT) reports are developed testing each specification. Because of the complexities of the two formats, the test plan for the DAT160 drive was much larger and longer than for previous generations of DAT. In total 450,000 hours (more than 5 years) of testing were performed on the DAT160 drive before release.

 

HP provides an MTBF Mean time between failures and bit ERT specification for its DDS products as a guide to the reliability that can be expected during customer use of these products. These specifications have, in the past, been generated using pre-production testing during the development of products.

The existing specifications for the DDS products (pre 2004) were:

MTBF: 400,000 hours at a 12% duty cycle

Unrecoverable bit ERT: 1 in 1x10-15

 

Based on field data gathered for the HP DDS-4 and DAT72 products, these specifications have now been revised to bring them inline with the reliability seen in the field by end users based on an assumed duty cycle. Therefore, this gives a much more representative measure of the real reliability of the product.

The revised specifications are:

MTBF: 125,000 hours at a 100% duty cycle

Unrecoverable bit ERT: 1 in 1x10-17

 

 

Parallel SCSI Ultra 320 is being superseded by SAS interfaces on systems and servers. This trend is being followed by the tape drive industry. In almost all ProLiant servers, parallel SCSI is being phased out and Serial Attach SCSI (SAS) is taking its place. HP is providing the DAT160 drive in three variants to assist users in the change over. We see SCSI variants being used in traditional legacy situations.

SAS DAT160 tape drives can connect either to an embedded SAS RAID controller or to a dedicated SAS HBA. All desktops, laptops, and servers now have more than one USB port. So with these three connectivity options, SCSI (for installed base), SAS for future server connect, and USB (for universal connect), the DAT160 drive is assured to protect customer’s investment in DAT technology.

 

HP has thought of everything with the DAT 160 drive. When HP launched the latest versions of the DAT72 drive, especially the DAT-72 USB, some customers considered the fan too loud for typical office environments. HP has re-engineered the solution and the DAT160 drive will benefit from this.

 

The original fan in the DAT 72 enclosure ran at 8200 rpm and generated noise of 28.0 dBA. The new fan in the DAT-160 enclosure is larger than in the previous DAT-72 enclosures and hence gives more airflow at a lower noise level. The fan runs at 3700 rpm and generates noise of 22 dBA, which is now much more “office friendly.”

Some other engineering adjustments also enabled the slower fan to provide the effective cooling required by the DAT160 drive:

 

• Improved air exhaust efficiency by increasing the size of the vent holes at the rear of the enclosure
• Minimized impeller cavitations by ”dishing” the fan vent, so creating a space between the rear panel and the fan

 

Improved stability of air flowing into the fan by increasing the length of the enclosure (so more space behind drive)

Now You Can Have Office Furniture That Promotes Perfect Posture

Excellent posture is really the foundation for strong physical health. Maintaining proper body posture not only allows your joints and muscles to remain limber, but it also increases circulation throughout the body. Good posture even helps you breathe more effectively because it allows your respiratory system to work more efficiently.

Unfortunately, many of us do not carry ourselves with the proper posture, especially at work. We slump, lean, or twist while we are at the office, and we may not even realize it. This leads to poor posture and opens us up for health problems over the long term.

Here's the good news: you can now get office furniture that actually promotes perfect posture! Here are some examples:

Office Chairs

Mayline Comfort Executive Chair with Adjustable Arms. This office chair is unique because its seat cushion comes with a suspended tailbone cut-out to take pressure off your back. This luxuriously padded chair also has convenient T-shaped adjustable height arms.

Ergo Mesh Medium Back Task Chair. This product features a contoured airmate mesh back to help maximize comfort as well as perfect your posture. It also has full tension, tilt, and swivel control.

Boss Grey Mid-back Ergonomic Task Chair. This chair can easily adjust to counter height, thus enabling excellent posture even when sitting at raised tables and counters. It also boasts a thickly padded seat, built-in lumbar support, and adjustable height and depth.

Office Star Professional Air Grid Deluxe Task Chair. This ergonomic chair has full lumbar support as well as 2-to-1 synchro-tilt control and tension control to give you complete control over your posture. The air grid seat and back also helps you regulate your body temperature.

Balt Ergo Executive Office Chair. Billed as the ultimate in ergonomic design, this chair not only has contoured and padded seats which slide in and out from the chair's back, but also a neck support to keep your posture perfect. Its stylish mesh back is complemented by its adjustable lumbar support.

HON Sensible Seating Series High Back Swivel Chair. This office chair maintains an ideal posture while its sculptured profile cradles your body in comfort. Its back and seat pitch are adjustable, and the frame and cushions automatically flex along with each body movement.

Executive Ergonomic Five-star Office Chair. This product's adjustable tilt mechanism and ergo-contoured lumbar cushions take pressure off your back so your posture stays the way it should be. And its pillow-top padding facilitates all-day comfort – even if you like to work long hours.

Ergonomic Seven-level Computer Workstation/Desk. This compact workstation keeps everything in front of you, so you don't have to compromise your posture by swiveling and bending. It has shelves or compartments for all of your office equipment, and its attractive wood finish fits with any décor.

Deluxe Glass-top Computer Desk with File Drawer. Like its name implies, this piece has a glass top which "floats" over the desk, which raises your monitor and helping you to stare straight ahead instead of downward – which often leads to a slumped posture. Also, there's plenty of storage space, including a drawer on top, a full-size hanging file cabinet on the bottom, and a mobile CPU caddy underneath.

Orispace Ergonomic Laptop Desk. You don't have to surrender to bad posture just because you're working on your laptop computer. This simple laptop utility table is height adjustable and has four tilt settings, allowing you to use it while sitting in a chair, on a sofa, or even at a countertop.

Cotytech Adjustable Ergonomic Mobile Computer Workstation. Here's a way to maintain good posture: don't strain your muscles moving computer equipment all over the place! This stand-up "workstation-on-wheels" is perfect for when you're on the move in laboratory, warehouse, or design environments, because it has a computer pole and radiating shelves that hold everything from a flat-screen to a keyboard tray to your CPU itself.

Always remember: posture does matter! And if your current office furniture is eroding your posture or even causing regular discomfort, it's time to make a change. You owe it to yourself and your health to get the office furniture that promotes your ideal posture!

Would I get excess emf radiation from headphones connected to my laptop computer?

I have read the claims that even earpieces connected to cell phones may transmit or even intensify emf to the head of the user.Since laptop computers are emf emitting devices, would plugging my headphones into my laptop also put me at risk for emf exposure?

I would worry more about damaging my hearing from loud sound than emf from a laptop 3 meters away.
