Achiev'ibles - Fixed

Just a quick forum topic to say that no patches will be automatically assigned for the next week or so. The site update changed some of Instructable's source code, my Perl scripts rely on that to find certain bits of information. As a result, I won't be handing out patches until I find time to fix it. That's all :) UPDATE: Canucksgirl's helped me find a fix/workaround. Yay! It should run again soon and we'll see if it worked. UPDATE 2: Yup, it worked. Patches were sent out again.

Can anyone prove or disprove that this is actually area 51? at some time pres. clinton gave that branch permission to deny it's existence. you used to be able to see it from a hill or something, but they fenced it off and may have cameras there here's the link to the image: http://tinypic.com/k9zvaw.jpg, if that doesn't show up just go to google images and search for "arial view of area 51"

A question - Can we post ideas than builds/crafts?

I was thinking about doing instructables on knowledge on survival in the wilderness. But I'm just wondering if it's acceptable here. It seems that most of the instructions I've seen are crafts or builds. Just a friendly question; if not; then I will find a way to make it craft-ish

Tall irrigated hedge to pre-cool A/C condenser? Answered

I am thinking about planting a hedge around our air conditioner condenser to increase its efficiency. This would serve as shade for the condenser and as a means to inject water to keep the plant cooling the air as it evaporates the water. When rainwater is available, an aquarium pump could "irrigate" the hedge. When not available, a switch could control a valve for a high-pressure drip irrigation system. Both could be controlled by the compressor circuit. Keep the hedge trimmed about 6 feet tall and with just enough space around the condenser for a workman to easily maintain the unit (at least 3 feet from the condenser). The hedge would have to be drought resistant and one that does not shed leaves or debris. Any thoughts about this?

How much should the capacitors capacitance be for my race track, car project? Answered

Hi im doing a project for my brother for christmas. Its a Drag race track thing, I have it all planned. Buuuuuuut for the cars I am using a capacitor, and a motor rated for around 6volts. WHAT should the capacitor's capacitance be?  A high capacitance or a low one?  I have a charging spot on the track to charge the capacitor, and then the energy stored in the capacitor powers the motor for long enough time to make it to the end.(Which is only 3 feet). Note:I found a small car that does just that but the motor doesnt work and the capacitor doesnt show the capacitance on it and I used my multimeter but it said DisC. I will post a picture of it later if it even helps. :(

A problem with my gun

Ok. I've scrapped the Mamba 12-G because there wasn't anything new there. I am bringing back the AR-4 Commando, but there is a problem I loaded my mag with 4 shots, and it has very low range on 2 of the shots The first two are fine, but not as great. The next two fly 3 feet and flop. The range on the other two is lower than my Mamba and earlier versions of the commando. I am using Banana inventor's mag for the gun....

Some questions about A/V stuff (home theater)

Hi all! Hope I got the right place for this.  I figured that there's someone in this community who can help me. My A/V receiver is about to give up the ghost.  A number of channels no longer work, and the sound is pretty fuzzy.  I know I need to replace it. I've always been terrible with A/V stuff.  I'm not sure what direction to go as far as replacing it goes.  Here's my issue:  The room I have the receiver in is small, so I don't need a lot of oomph.  I also don't have a way to run wires to rear speakers without people tripping over them.  I've gone without rear sound for a long time now.  I've never seen a set of wireless speakers that are reliable, so that seems like a poor option. I can't really do a "home theater in a box" setup, because they don't have enough inputs to add all of my stuff.  The things that currently run through the receiver are my computer (which runs our TV through a tuner card), a wii, an xbox 360, and a dvd player.  None of them are HDMI.  I use RCA cables for everything. The other thing that looked interesting is a sound bar, as they can apparently replicate surround sound without the rear speakers, but they seem to have the same problem that the "theater in a box" packages have. I don't know anything about receivers.  For example, I don't know if it makes sense to use a 5.1 receiver if I'm only running R, L, and Center speakers from it. Anyway... I'm not looking for brands or models necessarily, but rather, setup suggestions.  What kinds of things should I be looking into?  I can't be the only person with this kind of problem. Any advice that some of you A/V gurus can offer would be greatly appreciated!  The cheaper the better, here... as I don't use it all that much.  :) Thanks!

"Hydronic" A/C in an enclosed overhead space condensing and weeping ruining the ceiling tiles.

In an historic building, a remodel installing a chill water A/C air handler into a ceiling space now completely enclosed, is experiencing severe condensation and weeping onto the drop ceiling tiles.  I suspect a building code violation; "non vented installation". I am guessing a small powered fan/blower, cycling the air in the over head enclosed space with the "air-conditioned" environment. I am just guessing...  I would be honored to receive expert advice.

Testing my ability to use Lyrics to understand the meaning of a song

Okay, so I want you to tell me what you think. I am testing my ability to tell what a song means by it's lyrics/song title. Song: Deviate From the Form Artist: Scar Symmetry Okay, so already there is a clue. The word "Deviate" means to swerve, avoid, etc. So obviously, this song is about avoiding something. Now, lest look at the lyrics. First verse: I transcend my earthly form Through some questions never asked before Question the need to be a machine That responds automatically Okay, so "I transcend my earthly form". Transcend means to outdo, or exceed. So, basically, imo basically saying that you are doing better, or knowing better than a human. Knowing whats right and wrong about some questions that haven't been asked before. I suppose they mean something like "When will the next largest technological revolution happen?" Or "What inventions will destroy our planet in the future?". Like questions technological revolutions,  and future disasters or inventions. To back up that paragraph, read the next two lines. "Question the need to be a machine that responds automatically". Or to translate that, why do we need all these machines? Do we really have to be too lazy? What's next, self folding clothes? We do not NEED all these inventions. And later in the song, it talks about how there are changes, and turning into nothing. And what I mean by that, is that there will be so many innovations, that Earth will be pretty much taken over by robots. It will be nothing. All these machines are monotonous. They do not think, or have emotions. They are NOTHING. So to sum it up, I think this song means that they are trying to avoid becoming nothing. They do not like how there is an invention for almost everything ever thought up. They are staying in the past where we did not need all these gadgets
