Porch Enclosure

This is the white one:

And the aluminum one (not a macbook pro), which is refurbished:

I would only be using it to write papers, play music, play Sims, etc.
Just last week, I decided that the aluminum one might be better, but since the new white macbook with the unibody enclosure just came out, I’ve been having second thoughts.

I am so happy that I got my first mac yesterday, and I purchased MacBook Pro!!! It has the aluminium casing, a black illuminated keyboard. It has a smaller HDD, but you can get a portable one. This is definitely the best laptop! Plus, i am typing so well on this keyboard. H but this is your decision but I recommend this. P.S. Watch some videos of MacBooks on YouTube.

Check this out, and contact them to see if your DVD will fit, it should, as it is designed to fit a standard PC open bay, which is approximately six inches wide; http://www.shentech.com/usbx804.html

You can buy a new USB 2.0 external DVD drive for about the same cost as an external enclosure; http://search.ebay.com/external-usb-dvd_W0QQfclZ4QQfnuZ1QQfsopZ1QQxpufuZx

Make it a great day!

I recently pulled the hard drive out of my old computer which used Windows 98 as its OS. I want to purchase an external enclosure in order to get the data onto my new Vista system, but wasn’t sure if the archaic OS would get in the way of this. The old computer is a total loss so this seems to be my best option if it works. Any help would be most appreciated.

you can get an enclosure, or a IDE to Sata adapter and put it internal.

you wont have to format it, you can plug it in once windows has started. and you will be able to access it to get all your stuff off, or what you want to get off, and then format it to a diffrent file format if you want.

if you do come into problems on startup, if could be that windows has set the new drive as first boot drive. just enter bios by pressing DEL on startup repeatedly dill a blue screen comes, DONT CHANGE ANYTHING HEAR! just go through the menu and find boot sequence, and change the sequence so that it boots from the internal drive, and disable the external booting. (BTW, if you ever have a booting issue, were you have to boot from Disc, you should change the dvd drive to be first boot in there).

Is there a proper way to fold an enclosure envelope inside of another envelope without changing envelope sizes? Folding in half length-wise, width-wise, or into quarters? What is the accepted method for a professional letter mailing?

For a standard business envelope I believe you’d fold it in thirds.

Continued——-or 37 Hz and i know thats hertz but i don’t understand what they mean by tunning it? Or what hertz is, Thanks to all that help.

For ported enclosures the enclosure will be "tuned" to a certain frequency. The tuning frequency used will determine how the sub will perform as well as a few other factors.

Typically, an enclosure tuned higher like at 37Hz will be designed more for loudness and SPL. You will typically lose sound quality to gain output. To gain sound quality you will typically tune the enclosure lower. 33Hz is typically a frequency that will give a good mix of sound quality and output. This is all general as every sub will be different. All subs will have different tuning frequencies that they will perform the best at.

The actually frequency a ported enclosure is tuned to depends on several factors. These are a) the internal volume of the enclosure (not including the port or sub displacement) b) the cross sectional area of the port (height x width of port) and c) the length of the port. If you know all of these factors you can determine what the tuning frequency is.

Actually designing a ported enclosure is a bit more involved then just figuring out the size of the port you need to get a certain tuning frequency. You need to take into account other factors such as what cross sectional area you need to not have port noise. You also need to make sure the port is not too long that it is not practical for your application.

Good Luck!!!

I am building a device for an engineering class. I am looking for a tube that inflates vertically. Two ideas crossed my mind… The first was the old school hot wheels toy that had a push pump to launch cars. Our device would require inflating up but the idea is the same. The other is the large device you see in tv ER rooms that breaths for people. An tube moving up and down in a plastic enclosure.

I know this is very vague but all I need is a name for those types of tubes.
A bottle is a similar idea… But I need to be able to expand and collapse the object using air.
An axial pneumatic seal is the closest thing I have found.

If anyone else has some other ideas let me know.

What about an accordion style sports bottle?

Or should I just stick with a regular hard drive? I’m looking at a Raptor right now with a good price tag on it.
Would sticking a Western Digital Raptor in an USB external enclosure make a difference in the performance threw the USB 2.0?

No. The theoretical throughput of USB 2.0 is 480Mbits/second, or about 60MBytes/second, but in real life it doesn’t work that fast. Even slow, old ATA100 hard drives transfer at 50 MBytes/second,so faster than that is a waste on a USB 2.0 connection. Save your money until USB 3.0 comes out.

I have a new 2.5" hard disc drive for my MacBook Pro, and I know how to upgrade it if I were to have an enclosure for it, but I don’t want to buy one only to use it for ten minutes to upgrade my HDD and never use it again. I won’t use the enclosure with my old drive, so I don’t need it after i upgrade.

The main problem you’re facing is transferring the data without installing the drive in anything. Without having something to power the drive and allowing a connection you are not going to be able to transfer data. You need to have something to host the drive, either an older computer or some sort of enclosure. One thing you might try is buying an enclosure and then returning it again the next day. Since hardware is something that most places typically allow you to return this might work. I should check into it first before buying and trying to return it. Once you have something to host the drive you can use Disk Utility to format the new drive. Next repair permissions on your current primary drive. Then use TinkerTool System, MacJanitor or Onyx to force run all you maintenance routines, clear caches, logs and browser histories and downloads. Clone your drive using SuperDuper or similar software. Then swap the drives and restart your computer from the cloned drive. Check all your programs to make sure that everything is functioning properly. If you experience any troubles then use Disk Utility and repair your permissions.

I Need An Enclosure For two 12 inch subwoffrs are there any stores that sell them ?

If you are talking about home audio, none. Majority of the subwoofers for home audio are in enclosures already. Best Buy and other Car audio retail stores carry enclosure box for subwoofer. You can’t use car audio speakers for home use. You also need a power amplifier to drive the subwoofer and home audio does not provide amplifier for subwoofers for normal consumers. High end audio does carry power amplifiers, but the price are high. Hope this will help.

i want to make a dual ported 12" box enclosure

There’s no such thing as a ’standard’ ported enclosure.
