Web-enabled Kinect

There are Kinect hacks out there for robot vision, 3D scanners, and even pseudo-LIDAR setups. Until now, one limiting factor to these builds is the requirement for a full-blown computer on the device to deal with the depth maps and do all the necessary processing and computation. This doesn’t seem like much of a problem since [wizgrav] published Intrael, an HTTP interface for the Kinect.

[Eleftherios] caught up to [wizgrav] at his local hackerspace where he did a short tutorial on Intrael. [wizgrav]‘s project provides each frame from the Kinect over HTTP wrapped up in JSON arrays. Everything a Kinect outputs aside from sound is now easily available over the Internet.

The project is meant to put computer vision outside the realm of desktops and robotic laptops and into the web. [wizgrav] has a few ideas on what his project can be used for, such as smart security cameras and all kinds of interactive surfaces.

After the break, check out the Intrael primer [wizgrav] demonstrated (it’s Greek to us, but there are subtitles), and a few demos of what Intrael ‘sees.’

Web controlled Dark Crystal


[Reza] sent in his mood rock. Unlike other “mood” devices, instead of showing what mood you’re in, it shows what mood the internets are in. Two ShiftBrite modules are controlled by an AVR ATmega8 which then connects to a computer via USB. The assembly is placed inside of a piece of alabaster.

USB communications are controlled by the ATmega8 running V-USB (formerly AVR-USB) firmware. [Reza] wrote some code to control the colors from the web using Perl and AJAX. Head over to the web interface to set the colors yourself. We’d love it if a live webcam was added so we could see our mood on the rock itself. [Read more...]

Creating web applications for the iPhone

[Dominiek ter Heid] wanted to prototype an application for the iPhone that incorporated GPS. He experimented, and came up with a step-by-step tutorial on how to create a web application that would push GPS information to his iPhone through the use of JavaScript and AJAX. This tutorial will save web hackers who want to play with the iPhone 3G a lot of grief. Using Cocoa Touch, and a CSS/JavaScript pack called IUI, he successfully created a web application that looks native to the iPhone and is able to grab GPS information. The application integrates the GoogleMaps API with the GeoNames database. We look forward to seeing the types of creative applications that this prototype will inspire. What sort of web application would you want to create for the iPhone?
