Do you have to make seperate enclosures for each sub or can you just make it one big open space on the inside?
As long as you measure the air space right, you can have just a single chamber, but I believe you will get a harder bass with 2 separate chambers…
Will a driver have a lower or higher impedance in different enclosures? (small, large, sealed, ported)
This question is based on the idea that every kind of motor (system that converts electrical energy to mechanical energy) I know of will have lowered resistance under greater load, so I would imagine that if a sub had to drive a greater moving mass (e.g. had a larger port size) it’s impedance at a constant frequency would reduce. Any thoughts?
No, the enclosure affects the pressure wave only.
Any electrical charge generated by the woofer picking up that pressure wave(acting as a microphone) will be relatively negligible.
ok so today i bought a plastic tub taller then wide suitable for a small arboreal snake and would like to pick one up at the reptile expo coming up and dont know how i would heat a tub made of plastic for a snake that doesnt touch the ground because its arboreal also how well ventalated this tub should be and all that stuff maybe even a link or somthing to creating an arboreal plastic tub enclosure or somthing? anything helps thanks!
how does the heat mat attached to the side work? should i make it so the snake would be touching the side of the tub where the heat mat is while it son the perch? or does it heat the air or what?
Actually most arboreals do better in cages with more horizontal than vertical. All my arboreals are kept in wide, moderately tall cages. This makes it easier to control the temps at the bottom of the cage. Amazons spend a lot of time on the ground. Green tree pythons don’t. If this is your first arboreal, then I suggest you get an amazon. If you do purchase a green tree python than buy from a breeder who can show you mother and father. Stay away from anything listed as captive hatched or born. They should only be US captive born and bred or cbb. You’ll pay a little more but you won’t have all the parasite issues and other problems that come with imports. Import amazons are much more hardy but you’ll have to do parasite treatment with them as well.
I use heat mats on the side and top for arboreals when I’m keeping them in tubs. If it’s an amazon I might add one under the tub. You’ll need to drill holes for air along the sides and you can always cover some if it seems to be drying out too quickly. I attach the heat mat with electrical tape or duct tape on the outside of the tub. Heat mats will heat the air nearby and the probe for the thermostat should be placed at perch level on the warm side. I have a caresheet on both amazons and chondros on my website.I think I’ve got pictures of some of the tubs somewhere if you want to e-mail me. There’s a link on my site for e-mail.
It’s something that seems to have just been invented in the last two years or so. I assume that it’s to muffle the sound of the drums so that they won’t overpower the audience or the rest of the band. Still, I think it’s really weird, especially since people have played drums in bands for generations and have never done this before. Why have they started doing it now all of a sudden?
They can also be useful in roadhouses for shielding the drummer from flying beer bottles and zippo lighters.
I have an internal drive that I made into an external one by an enclosure. The enclosure itself is aluminum. I try to put a fan right over it in order to keep the drive very healthy. Is it going to be a counteracting force to the drive’s spin if I put a PC fan right over it? I notice sometimes a transfer speed decrease when I put a fan over it.
Edit:
I actually didn’t "see" it decrease. I was using WBFS manager to transfer Wii iso’s to my external drive, and it didn’t show me a transfer speed. I just guessed by my sense of time.
Electric motors work by rotating a coil of wire in an electric feild. So i guess in theory that that field could interfere with another motors field.
In practice though I think the strength of the field reduces in proportion of the distance squared. And as it was a very weak field in the first palce i think its unlikely.
Run a few HDTune benchmarks without the fan, then put a fan on top and run them again. If it is causing a problem you should only need to move them apart a tiny bit for the interference to stop. Just try a few benchmarks until your sure its ok.
The problem is that the hard drive is actually from a external western digital hard drive 500gb My Book series, and its hard drive enclosure messed up. I don’t have any more warranty on it, so I was thinking of just buying a enclosure for the hard drive. I just don’t know which one to buy, and is compatible with Western Digital. Can someone please help me out.
The only thing you’ll need to know is what connection interface the drive has. Crack it open and look. It’ll have a connector with 4 large pins for power, and either a set of pins with a (usually grey) 2 inch wide cable sticking out, or a smaller cable about 1 inch wide. If it’s the wide cable get an external drive with IDE support, if ti’s the 1 inch wide cable then get a SATA compatible external drive. Pictures of both cables are easily found on images.google.com.
Hello, i have a 3 year old Mediterranean Spur thighed tortoise ( Scientific name: Testudo Graeca )
Anyway it is cooler because we are going into winter so she is inside she has a heat lamp UVB etc eats 100% weed diet ( dandilions chicory etc ) in her enclosure now she has a tray of live grass, pebals branches, basking rock and a "reptile" bowl of water, How can i make her Enclosure more intesting??
Thank you
Several possibilities.
Play with the food-
- bundle and hang plants for the torts to eat
- offer edible flowers
- if they eat pelleted or cubed hay, or Mazuri pellets, place some in odd corners of the habit
- raise some edible plants in low trays. Rotate the trays in so they can graze on them
Give them toys-
- some tortoises bump and move balls, like practice golf balls, Whiffle balls, etc.
- offer it things to climb over- ramps, bridges, hillsides, mostly buried pots on their sides, etc.
- offer different surfaces to walk on. Some people offer shallow trays of soil, pebbles, sand, etc. they can rotate out to clean or change up.
Let them hide-
- Hiding places in planted areas
- warm end humid hide
- cool end drier hide
I PURCHASED THE SATA $ IDE 3.5" HARD DRIVE TP USB 2.0 AND e-SATA ALUMINUM ENCLOSURE CASE ABOUT 2 YEARS AGO AND I HAD A PROBLEM.
I TRY TO ACCESS I FILE IN THE HARDRIVE BUT IT TELLS ME THAT I DONT HAVE PREMISSION TO ACCESS THE FOLDER. HOW CAN I ACCESS THE FOLDER WITH NO PROBLEMS?
It depends on the operating system and it’s security measures. On Windows 2000/XP/2003/Vista/7 you may just need to log in as an administrator and change the permissions of the drive or folder by right clicking and going to properties. There would be the properties tab.
If you are using Linux, you’d have to log into root and possibly unmount and remount the disk so you have permission or use chown and/or chmod on the directories and files.
When my laptop broke down I transfered the hard drive into the enclosure thinking I would be able to get the data, but my new laptop wouldn’t recognise the hard drive. I thought maybe it was because there was 2 platforms or something. But my friends laptop broke down and I put his hard drive into the enclosure and it worked! it opened up as another drive and he was able to retrieve all his data.
the only difference that I can think off is in my hard drive I used a password to access my account; my friend never had a password.Any ideas on how to get my hard drive to open?
Will I have to boot it from the external drive at the beginning so I can sign in and remove the password?
See if perhaps your hard drive is configured as a Master drive; it is possible the old and new drives are both configured as Master and therefore the one in the laptop is dominant.
I don’t know about laptop drives, but in regular PC drives, there is a jumper setting to make it a Master or a Slave. Check you drive for the jumpers.
I have been trying for 3 hours and my brain is about to explode. Can someone please show me how to solve this problem.
You have 800 feet of fencing and you want to make two fenced in enclosures by splitting one enclosure in half. What are the largest dimensions of this enclosure that you could build?
800/5 is 160
Make it 160 feet wide and 160 feet long and then put a fence down the middle of it
The other guy is probably right.
