PS3 Eye As A Webcam On Windows

September 30, 2008 by Caleb Kraft 12 Comments

The NUI Group has been working hard to bring the PS3 Eye to windows. From the factory, this device has pretty impressive specs, but no windows drivers. After a bit of hacking, they’ve developed a driver for it and released it on their forums. The main reason they are so interested in it is that it can capture full frame at 60 frames per second, making it perfect for multi touch sensing. Now that they’ve got it working with windows, they’re working on a custom PS3 Eye filter for touchlib.

Twitter Security Cam

June 16, 2008 by Juan Aguilar 10 Comments

It seems that people keep coming up with ingenious things to with Twitter. Reminding you to water your plants is relatively inventive, but for shear practicality, [Shantanu Goel] created a security camera using a webcam, a few freeware apps, and a Twitter account.

To make this work, install Motion on a system running Linux. As its name suggests, Motion is a free motion-detecting application that monitors movement in a webcam’s field of view. Once installed, it should be configured to take a snapshot of the event whenever something moves; with the locate option turned on, it draws a square frame around the area where motion occurred. The program includes http server functionality, so the photos can be viewed from a remote location. When all of that is properly configured, motion can be set to trigger cURL, Wget, or [Goel]’s Perl script to post a message to Twitter about the event. From there the Twitter account can be configured to send text messages to a phone, creating a virtually instant notification of motion sensed by the webcam.

Simple Linux Robot With IR Camera

May 25, 2008 by Juan Aguilar 2 Comments

Here’s something else we found while writing up our duplicate Ikea Linux Cluster post. [Janne] also built this simple linux robot. The robot uses the Qwerk robot controller, a webcam with the IR filter removed (something like this one), a usb WiFi card, an IR spotlight, and a set of repurposed model airplane wheels. The WiFi adapter and webcam attach directly to the Qwerk via its on-board usb ports; the servo motors are also connected via built-in ports. Although [Janne] doesn’t post specific instructions, the Qwerk platform seems fairly easy to work with. Have a look at the Qwerk overview for more information.

Webcam Laser Rangefinder

This has been around for a while, but I thought it deserved some attention. [Todd] used a laser pointer, a webcam, some trig and (sigh) some windows development tools to create his own laser range finder. Given the position of the beam strike and that the camera is located at a right angle to the laser, calculating the distance is pretty simple. This could be handy if you’re building a bot for defcon…

Optical Recognition LED Control

I probably shouldn’t find this as worthy as I do. It’s the optical recognition equivalent of wiring up a LED to a switch,, but it just appeals to me. [Ashish], one of our favorite optical recognition hackers of late, sent along this product of his boredom. If only he’d give us some source and a wiring diagram…
