How to make a pole camera to check bird nests?

I need to make a camera (a cheap one is ok-even a web cam) that is mounted on top of a pole, that I can lift up and take a picture (or video) of a nest. I need to be able to see where I'm pointing the camera, so I need a monitor I can connect with the camera, and then be able to remotely trigger the camera. Any suggestions on how to rig an inexpensive setup like this?

Tall PVC Flagpole

I know there are already instructables that show how to build a PVC flagpole, however what I need to build is different.  I want to build a flagpole that is 15-20 feet tall and can withstand relatively strong winds.  In addition, it needs to be portable and be able to be disassembled, so the sections of PVC can be no longer than 5-6'. I am worried that just using standard PVC connectors to connect the different sections will not be strong enough to withstand the wind.  This flag will be placed in the sand on a beach facing the ocean, so a 15-20' tall flagpole will need considerable strength. I figured I would use a 5 gallon bucket filled halfway with cement as the base, and then bury the base in the sand so it is sturdy on the bottom.  From there, I am having trouble coming up with alternative ways to attach the sections of PVC (besides connectors) that will withstand high winds and not snap.  Do you think the connectors will in fact be strong enough? If not, are there any good alternatives? Lastly, would drilling holes into the PVC (to attach eye hooks) compromise the strength of the PVC too much?

Fire Pole!

My house has undergone some small renovations over the past two weeks, the best of which was just installed this morning: a fireman's pole for sliding down!My boyfriend has also got the ability to climb back up... I have not yet attempted that.Here are some pix and videos. The construction is not quite complete yet so it's still all sawdusty and unpainted - looks like a workshop more than a home, but you know it's at least half workshop anyway.Down the pole: Up the pole:

Just wondering, what's the best way about making a device that is sort of like a tripod, without the pan and tilt or left and right? just need the pole type device to go up and down like a car antenna? Is it possible to control this via remote from like 100 - 200 feet away? and possible to control height of the poles?

Mounting a blade sign to a tent pole—best methods?

Hi there! I'm doing deco for a large event where there will be a line of vendors in pole tents—the kind you typically see at festivals and fairs, with a white top and stuff. I want to see if it's doable to have blade signs hanging for each vendor, mounted to one of the frame poles of the tent. The signs' construction is variable depending on the mounting methodology, I'm thinking the more lightweight the better. One method I was thinking about would be using zip ties to snugly attach a 90 degree bracket to the tent frame pole and hang the sign from the perpendicular arm, but I don't know if zip ties would be sturdy enough. These don't have to withstand a hurricane but do need to be sturdy enough to withstand the occasional nudge or shake by workers/drunk people. I should also emphasize that the tents will be rented, so no permanent alterations can be done (i.e. no soldering brackets to tent frames...) Thoughts/suggestions/possible drawbacks? THANK YOU

Single and Triple Phase? Answered

Ok, so I thought I knew how the power phases worked and then I got myself confused.  Our house has three phases and it offers power at 120v, 240v, and 480v (or at least can I think).  All three wires on the power poles go to transformers and then to the house and so on.  I have seen houses that just use one which I think I understand unless they try to get a dryer then what do they do.  I am going to ask a little more than phases here to just to make sure I get this.  In you wall outlet one is from a line on the power poles correct? and the other is ground which works because at the generator site the electricity is grounded on one side.  Now before I get ahead of myself, how can there be single and triple phases in a 120v outlet and what exactly are they.  Now, at a 240v outlet you have two hot wires coming from the power lines right, and then one ground.  Now I think all the lines on the poles come down to 120v, so how do you get 480v from three 120v lines.  3*120 does not equal 480v.  I am confused.  Also will having triple and single phase even effect how things work.  Like we have a 120v single phase compressor and it works just fine at our triple phase hose.  So it doesn't really make any sense at all.

3.5 mm 4 pole splitter question (for use with ipod touch)

Hi, I'm attempting to put together something that is conceptually simple -- making a splitter for the 3.5 mm 4 pole audio jack so that one end supports a mic and the other a pair of headphones. I'm doing this because I want to hook up a better quality mic than found in the store-bought iphone headsets. However, after putting it all together, I just can't get it to work with my ipod. I've followed these pinouts (where 1 is the tip and 4 is the base): 4-pole jack 1. Left Audio 2. Right Audio 3. Ground 4. Microphone 3-pole jack 1. Left Audio 2. Right Audio 3. Ground Ive verified that all the connections are good using a multimeter. But when it comes down to actually recording with my ipod, I can't get the line in to work. Has anyone does anything like this before? Any ideas what might be going wrong? Is is it possible that measurements on the 4 pole jack isn't standardized and that the one I have doesn't actually fit the ipod correctly? Perhaps I'm completely wrong about how to connect the wires. So just in case, this is what I did: Line-in: Pinout (P/O) 1 and P/O 2 ---> P/O 4 (on 4-pole) P/O 3 --> P/O 3 on 4-pole (on 4-pole) Line-out: P/O 1 --> P/O 1 (on 4-pole) P/O 2 --> P/O 2 (on 4-pole) P/O 3 --> P/O 3 (on 4-pole) So yep, that's it. Any help is much appreciated : )

Safe removal of a ~30' HAM Radio Antenna

Hello all, I have a friend who has a 30 foot (approx) HAM Radio antenna mounted on his garage.  The pole base attaches to two brackets which are anchored to the exterior wall of a garage.  Near the top of the antenna, 3 cable anchors connect to brackets on the roof.  He wants it gone, and wants me to take it.  But, this must be planned out carefully.  The pole could be lowered 3 feet or so, so it makes contact with the ground.  It could be used as the fulcrum to lower this down into his backyard.  Power lines are not in proximity.  If several people were on the roof, could that point be used to lower the antenna gently to people on the ground?  My concern is that the construction looks aluminum. The pole is 2" steel pipe.  ButI cannot be certain on the actual antennd contruction or weight.  There are 3 or 4 small boxes mounted at various heights on the pole.  I can't image they weigh too much.  Can anoyone tell me what there are used for?  Occasionally, a red led will blink on the bottom of the case. I am excited to acquire components that one day may help me get my amateur license.  But I am concerned about how to safely do this, and will not attempt without a very clear plan.  I don't want it to end up being too heavy, and slingshotting the people on the roof (like something that would happen to red green).  I also need to insure his roof is not damaged.  I think the brackets will be left on, and the cable cut at the base.   Any knowledge is greatly appreciated!

(newbie) materials to build a sliding "inverted-L" stand / pole

Hi folks!Just discovered this fantastic website! I have this very cool idea for a 'ible I am working on and cannot wait to put it on the site. For now and as a first step (sorry, I am a newbie!), I am simply trying to build a simple stand with the following "inverted L" shape:- - - - - - - - - - - - - -||||(floor)Think of tje coat hanger in the picture below, only sturdier and with a single vertical pole (and without the wheels/mesh at the bottom). Also, the vertical pole does not need to be telescopic: as long as I can adjust the height of the horizontal pole I am happy. This could be done eg by mounting the horizontal pole on a "tee" fitting; but then how do I make it fix into a given position/height on the vertical pole (and still be adjustable)? (I had a look at this 'ible -- https://www.instructables.com/id/Third%2c-fourth%2c-and-possibly-fifth%2c-hand/ -- , but I don't understand how the tee fitting gets fixed into position: welding?)I am thinking of using pipes or PVC from a hardware store. My big question is: how can I get the vertical adjustment feature using such readymade materials? Thank in advance for any help!James KirinPasadena, CA
