I hear this is a burning question for a lot of people, so I will attempt to provide some detail here with both a Mac and PC perspective. I'll go over a lot of things, seeing as people seem to want to know all about webcams!

Step 1: Get a Webcam

You will need, alas, a webcam if you are to partake in the festivities. If you have a Mac, you're in luck as long as it's not a Mac mini! You probably have one built-in. To check, click the apple in the top left of your screen. Click "About This Mac". Click "More Info...". In the bar on the left, click "USB". Now check to see if "Built-in iSight" is listed. Also, if you're using any non-built-in webcams, this is where they should show up. I've included a screenshot of Photo Booth, the bundled Mac program which came with your computer (if you have a Mac with a webcam), and a photo of the iSight camera on a MacBook.

If you have a Windows computer, you probably don't have a webcam built-in, and as such will have to buy one. What you are looking for is a "USB webcam". They're sold all over the place, and you get what you pay for. You can pick up a cheap Logitech for 25 dollars, and I wouldn't recommend spending more than 30 dollars until you know you're really a keen webcam person. Look for a high framerate (30 fps or more) and at least a 640x480 resolution. You may also want a built-in microphone, which is a pretty standard feature. (It's hard to find a webcam without a microphone, actually, but if you're buying a really cheap one, do check!)

It's worthwhile going to a large computer store (CompUSA, Compusmart, Future Shop, Best Buy, or whatever's large and near you) to have a look, as they tend to have one of each webcam set up and connected to a computer, so you can compare image quality. Some of the more expensive models do fancy things, like tracking (the camera follows you around the room) and have nice zooms, which may be useful, depending on your intended use.

I've included a photo of the Creative WebCam Vista Plus, which is a really cheap, very basic webcam, which is Mac and PC compatible. It's one I'd recommend for people just beginning to mess around with webcams, and you can find it and other Creative webcams for $15-20 USD if you shop around.

Now hook it up to your computer with the included instructions (most of them are plug-in-and-use now) and move on to step 2!

Step 2: Get to Chatting!

Now you've got a webcam, you probably want to talk to some people. We'll cover a few scenarios here:

Let's say you want to talk to your friend, who also has a webcam, on a Mac. There are a few options, the easiest of which to use is probably iChat, a program which both of you already have. All you need is a .Mac account and you're set up automatically. Easy!

Windows Live Messenger is your friend here. Free to download at get.live.com/messenger. It even allows full-screen video conferencing! You will both need a Windows Live account, but it's free, and you can get it at the URL I just gave. If you don't want to have to download things (and frankly, who does?), you may want to check out webmessenger.msn.com. It's an online version of Windows Live Messenger, so you'll still need that Windows Live account (which, by the way, you have if you have a Hotmail account). But you oughtn't need to download anything.

Chat Rooms
userplane.com is one place to look for chat rooms, and ivideochat.com is another. Be extra safe online, and never meet up with anyone in real life from any of these video chat places. I can't really offer much other advice, except "don't download dubious downloads" and use as much common sense as possible.

Your project was not published because it could use a bit more work before it goes public. If you are planning on submitting this project to the Burning Questions group then you are going to have to do a bit more explaining about the process before we can accept it. First off, start by adding in images or screen shots to each of your steps to help users see what you are explaining. Additionally, adding in some more info about where to get the programs and what kinds of cameras someone should by would be useful. The bar has been set pretty high for answers to Burning Questions so I just want to help your answer be all that it can be. Please make the changes to your instructable and then republish it and I will be happy to remove this comment, make it public, add it to the burning questions group and send you a t-shirt. Thanks for your project, Noah
Hi noahw! Thanks for your comments. I spent another hour or so on it, trying to incorporate your feedback. (A lot of the additions are notes in the images, just so you know.) I understand that the standards are high for Burning Questions, so let me know if I need to keep working at it (though I can't think of too much more to add, as a lot of stuff about setting up the actual webcam is dependent on which webcam the person buys). Hope this satisfies your requirements, and if not, just tell me! Thanks for your feedback, Grant
Looks great - Thanks! I'll send you a PM with shirt claiming instructions in a minute.
