Catguard #1 by Home security video camera

This is first vid associated with a simple "guardbot" I'm setting up to look after my (presently) 8 mo kitten.After adding a catflap to the back door, I discovered at least 2 of the neighbouring toms have been coming into my kitchen (and maybe elsewhere in the house) in the early am's to (a) steam food, and (b) beat up the kitten.So I've started building various simple contraptions to try to keep the strangers out, but allow the kitten in.First prototypes were various combos of "dumb" IR and sonar sensors attached to noisemakers. By changing the noise from time-to-time these kept the stangers out, but allowed the kitten to habituate to the noises (and thereafter ignore them) the first few times she was coming & going.But forseeing this won't work forever with adaptive systems like tomcats, I'm moving it up a notch.The next system will try to visually ID which cat (or -- harder -- cats plural) are entering an area, and take appropriate action.Appropriate actions will include lights, noises, movements, and -- taking a leaf from Trossenrobotics -- a stream of water.This is vid of the first (couple, maybe) of experiments.I've linked an IR camera wirelessly to a small box of tricks based on an avr32. After managing to get g++ 4.3.2 and (more importantly) libstdc++ up on the avr32 (seems to be a world first ;) I've been tinkering up some very simple OPENCV-based code to examine the vision stream.Step 1 is obviously decide whether "a" cat is presently in view. Later we'll try to decide *which* particular cat it is (or, maybe before that, whether it is or is not my kitten).The vid shows the raw vid wirelessly directed to a crappy home-built wifi-based-DVR (it takes low-res vision and recording/programming commands from 802.11 packets) showing the not-based quality of the IR camera.At the time of this recording the kitchen was essentially black. (At some point a motion-sensing light may or may not have switched on during the sequence, but the cam didn't have enough light to shift to its colour vision mode).The 2nd 1/2 of the vid shows output from the avr32 super-imposed onto the input stream.If a "cat" is detected, a circle is placed *roughly* around the area on the screen the head is supposed to be located, with labels indicating date & time of the detection event.The software that takes care of the event handling is (or will be :) documented on my robot blog at AUSROBOTICS.

http://www.rewards1.com/index.php?referrer_id=293797OK I will be showing you all how to get free stuff like I got my year of xbox live along with Call of Duty 4. You can use this method to get game systems, any other electronics, jewelry, Wii points, Nexon cash, iTunes credits, and anything else that you want using a custom order form too!How does this work and is this legal?When you buy an XBox Live Points card you just enter the code and Microsoft credits you with the points right? Well, if you follow the directions below there's a site that will EMAIL these codes to you! They buy the codes from Microsoft (or whoever, depending if u get Wii points, NX cash, iTunes credits etc.) and they get paid by the sponsors that advertise on the site. So yes, this is 100% legit and legal. Cool huh?The only downside is you need to be from USA, Canada, UK or Australia (that's just how the advertisers work).OK what do I need to do?First thing you need to do is get a "junk" email account. (I recommend gmail but yahoo or hotmail is fine) Since you're going to be getting a lot of junk mail you're not going to want it all going to your real email address, so this is what this new email account will be used for.Step 1: Sign UpGo to http://www.rewards1.com/index.php?referrer_id=293797and sign up.Once you get there click SIGN UP on the menu bar on the left and fill out your information.They will ask you for your email. I recommend you give them your real one because this is where they will email your XBox Live code to. If you give them your spam one you might accidentally delete it. The site doesn't spam you its all the offers you will be doing that send the junk email (more on that in step 2).They also ask for your address. Don't worry too much about this all they need your address for is to mail you prizes. (I've personally had them mail me Resident Evil 4!)After you signup they will send you a confirmation link to your email address you entered. Click the link and you're done. The email should come pretty quick (usually instantly). And make sure you check your spam folders.Step 2: Complete OffersNow that you've signed up go ahead and login, its time to start earning points!Once inside you can check out the prize list. You'll see the XBox Live 1600 points card is 20 points - basically 1 point is 1 dollar. You earn points by completing offers and you should be able to get 20 points in about an hour or two.To earn points click on "Available Offers". There you will see a whole list of offers and how many points you'll get if you complete that offer. When filling out an offer you don't have to give your real home address or phone number. And make sure you use your spam email account because believe me you will be spammed. Also, be sure to check your email occasionally for those offers that require email confirmation otherwise you won't get credited for completing the offer properly.NOTE: The higher paying offers generally require a credit card and may charge you a few dollars (usually for shipping and handling). Basically you're spending a few dollars to get 15-30 points. You see where I'm going with this. If you do enough credit card offers you can pretty much get an XBox 360 Console (retails $350) for $50-60. (I'm actually in the middle of working my way towards one myself. I'll write an article detailing how to do this later if enough people want)Here are a few tips for filling out offers:1. Read the offer carefully so you know exactly what to do to get the points.2. Delete cookies before every offer3. Complete offer with realistic information4. Use a browser that accepts cookies and turn your security down5. Let each page load completelyAlso remember that even though most of the time you'll get the points 5-10 minutes after completing the offer, some may take up to a day or more (depending on the offer). So don't worry if you don't see the points just keep going they will appear if you've done everything correctly.Step 3: Claim Your PrizeAfter you have enough points you can now go to "Available Prizes" and see what you can cash those points in for. This is the fun part. =)They have a ton of prizes. You'll see stuff like consoles (XBox, PS3, Wii), video games, iPods, etc. The XBox Live cards are in the "XBox" section and will be emailed to you. Physical prizes like iPods and video games will delivered so make sure your address is correct before you claim a prize that requires shipping.ALSO if you want ANYTHING not on the site that is on Amazon or Ebay all you have to do is click on the Custom order tab and explain what the item is and the URL to the place where they can buy it for you1 point = 1 dollarAND THAT'S IT!Comment please and don't be afraid to try it out
