I have tried for a long to find a tutorial on how to do classic copper and brass soldering. I mean, is it anything like electronics soldering, at which i am fairly apt at? Do you use a a rod or a torch? ...How to mend a broken copperpipe? make the most classic pipejoints? How to mend a broken brass lamp that has lost a thingie? What kind of solder does one use for different materials? In all it's simplicity I am looking for an entrance level tutorial into the subject, explaining what basic tools one need and outlining how to do a few simple things.

How to film 3D videos on youtube? Answered

So if you are unfamiliar here is just one example of a 3d video on youtube: http://www.youtube.com/watch?v=zBa-bCxsZDk. I know this is an animation, but it uses the same technique. Basically the way these movies are made is by filming with 2 cameras about 3 to 4 inches apart. The video from the right is put on the left, and the left on the right. This way if you are doing the cross eye technique it appears 3d. My question, is could you film with one camera, and cut off parts from the sides for each to make it appear 3D, even if you only use one camera?

Alternative Photography Project

I am currently in the Advanced Photography class at my high school. One of the assigned projects is simply titled "Alternative Photographic Technique." Basically, we have to create an image without using 35mm film (not digital, either). The specific techniques that he recommends are:Photogram-arranging objects directly on the photo paper, without using a camera at allHolga- The teacher has a few Holga cameras with 120 film for class use to take artistically lousy imagesPinhole Camera- If you don't know what this is, you probably can't answer my question anyway.Cyanotype- a special emulsion is painted on watercolor paper, then exposed in sunlight under a large transparency. Search "cyanotype" to see what it is.Polaroid image transfer- an image taken with a Polaroid Two-Step camera is transferred from the film to watercolor paper-looks cool, but expensiveCan anyone suggest other interesting ideas? I'd like to keep it simple and inexpensive, and I have to have 8"x10" total printed image.Weissensteinburg? Are you there?Edit 5-12-08: I have printed some 5x7s with my cool new technique.

Tricky batch stuff...?

This isn't exactly a conventional question, but it's a question nonetheless.  The thing is, I'm thinking of starting a forum for all the tricky techniques and methods with batch (it wouldn't be a great instructable as it would require a lot of previous knowledge). So, I'd basically just have an index with all these different segments of how to do tricky stuff (such as advanced techniques for piping and other random stuff). The only problem is that I don't know what to make it on, so I'm trying to target people who've read all the instructables and are still missing that extra bit of information. Now, you could say something like "do whatever you think is hard", but the thing is I work better when it's at the request of someone else (basically I like to help people, and I'm abusing that natural urge). So, if you're experienced in batch but are curious about anything (perhaps how to ignore every rule in the book and put 50 nested for loops within your script), please post it below. Thank you. --EDIT-- I've started rewriting my batch tutorial, so most of the stuff you comment will go into that... somewhere.

How can I use a digital camera to obtain DSLR looking footage?

I recently bought a new video camera, the Panasonic HC-V750. Don't get me wrong, its an amazing camera and I love it, but I made the mistake of spending 500 bucks on this instead of a DSLR. I am trying to make a short film and want it to look professional. However, I know that this is almost always achieved using a DSLR and nifty editing/lighting techniques. I have the editing and lighting techniques down, but is there any way to adjust my video camera so that I can get DSLR-like quality? Like adjusting shutter or something? I know that the advantages of a DSLR are their large sensors and supreme ability to capture light using these sensors. Can I achieve this, at least a little, with my video camera? I can adjust the white balance, shutter, iris, and focus, on my camera. Any links and/or help is greatly appreciated!

Image Processing Tutorial : What you do for your images?

Image Processing Tutorial : What you do for your images? Are you in possession of images you want to convert in to digital form? Or simply you would like to perform some operations to enhance their outlook?  Similarly if you just want to extract some useful information from them, all you need is a photo house that carries out image processing. This is where you can have a photo you want manipulated made  the input as you give  specified characteristics you want included. To do image processing, you may have to apply a set of signals that can give you   the desired results. There are three distinct steps to follow in any image processing. They include: Importing images using a scanner or a photography Analyzing and manipulating images using enhancement and compression methods Altering the results we obtain at the output level There are plenty of reasons for carrying out image processing; the reasons and purposes are as follows: So that you can easily observe the parts that are not visible Restoration and sharpening the images for the purpose of making them look better Image retrieval – if you are interested in any particular image, you can have it retrieved. Identify the number of elements making up a pattern Distinguish the object and its image. There are   two methods that can be used in processing any images. Digital Analog If you are analyzing hard copies and printouts, this is what is referred to as visual techniques.  It involves use of various fundamentals and image processing techniques. You need to make use of technicians who are vast in image processing. They may use visual techniques and apply a combination of individual knowledge and experience in image processing. If your pictures are in a digital form, you may employ digital processing techniques to manipulate those using computers. Images collected from sensors and satellites can be manipulated to get the real images or data.  To do this, you need experts who can take the images collected into a number of phases before coming up with the required images.  They must have the latest skills to help them get over flaws and get original information. The data or images collected may be taken through the following phases; Pre-processing, Information extraction, Enhancement and display. Other than image processing service, you may need team   to deal with computer graphics. This is where any desired image is manually made using physical models. It could include lighting, environment and natural scenes. This graphics can be used in animated movies, computer vision and plays. It can be used to create moving images to depict a story. Generally, imaging is key in image processing. The designers should consider a number of factors including; Human visual – where the designers consider the psychophysical process that takes place in human beings as they make sense out of information they see and receive. Lastly in all these, ensure that you get a clipping path company that is vast in imaging and which can work hand in hand with you to ensure that you get the required results.

How does this rotation control mechanism work? Answered

I've been trying to figure out a good technique to control the motor rotation in a split-flap display. I've found two methods that I want to compare. One is with a NEMA8 stepper motor (I want to try to keep things small and easy to replicate), the other technique is with a method I've only seen in one place, and I'm not exactly sure what's going on. You can see the video here. From what I gather, they have a DC Motor, that controls two discs. The right hand disc acts as your zero reference, and the left references each flap in the split-flap display.  I can faintly see a red light flashing that I think is on the left hand connector, that flashes every time a groove in the wheel spins past. The right hand wheel only has one groove in it, and when it's facing straight down, you'll see the LED turn on. I imagine the LED is turning on to let the programmer know that that sensor is picking up the groove, but I don't think it's the sensor. I also think those grooves are super important to the sensing, but I don't know how. I know how ball mice work, but those require a IR emitter/receiver on each side of the wheel. I can't see that here (though it could be hidden). So my question is, how does this work? Or, if it's a better question, what is the simplest/cheapest way to get precision accuracy (and the ability to zero if things shift out of place) out of a DC motor without programming the stopping points? Any help is greatly appreciated.

Multiplexing more than 100 7segment LED displays with a microcontroller

What are the multiplexing techniques to interface about 100 7segment displays to a 8-bit microcontroller (say 8051). If I hook up a row of decoders to the control pins of the display array on a common bus, I guess I might acheive it. But I doubt if there would be any flicker while doing so. Say for example, If I have 64 pairs of 7seg digits to be controlled, I may do a round-robin multiplex to the tune that each pair is ON for about 1ms in every 64 ms. Will that be possible, given that the duty cycle and frequency are of that order? Thanks for your invaluable response. Regards, Ather
