We’ve seen hundreds of builds tinker around with the GPIO pins on the Raspberry Pi. They’re great for bridging the gap between physical sensors and a virtual world, but there are a few more unused and ignored pins on the Raspberry Pi. The folks at the Raspberry Pi foundation are finally giving these unused pins a life of [...]

What do you do when you have a microcontroller you’re trying to optimize? One method is using a debugger, but for AVRs and such that’s not a very common technique. For lower-level electronics projects, it’s nearly impossible, even. [Cnlohr] built a small Minecraft server that listens to in-game redstone circuits, but the performance of his real-world [...]

Last week we saw [Todd]‘s solution to getting a tripod out-of-the-way when filming a few DIY videos. It’s an overhead camera gantry that allows him to move a camera around his garage workshop without a tripod getting in the way. This weekend, he’s back with a new and improved version. It’s a vast improvement over [...]

[Derek] likes to get a little bit of drivers-eye footage when racing his motorcycle, but there’s an inherent problem with mounting a camera to a moving and tilting platform. When he leans into turns, the camera can’t keep the horizon level. Cinematography and electronics go well together. so [Derek] built a horizon-stabilized camera mount for motorcycle videography. The [...]

It’s neat to watch these lilies open and close during the time-lapse movie. But what makes it even better is to see the camera slowly move during the time-lapse event. It’s thanks to a special dolly which the photographers built for this purpose. The system is based on two curved and inclined pipes which make [...]

[Michael H] tipped us off about this guide to using view camera lens parts with DSLR cameras and lenses.

This laser light painting setup can even control the camera. But it probably will not work with your average point-and-shoot.

Since we’re not high-end camera aficionados it was a surprise to us that the hot shoe that allows a camera to interface with a flash module has changed rather dramatically over the years.

3D Event:
Chaos Communication Congress 28th (28C3) 2011 Abstract: This project investigates techniques to track the 6DOF position of handheld depth sensing cameras, such as Kinect, as they move through space and perform high quality 3D surface reconstructions for interaction. While depth cameras are not conceptually new, Kinect has made such sensors accessible to all. The quality of the depth sensing, given the low-cost and real-time nature of the device, is compelling, and has made the sensor instantly popular with researchers and enthusiasts alike. The Kinect camera uses a structured light technique to generate real-time depth maps containing discrete range measurements of the physical scene. This data can be reprojected as a set of discrete 3D points (or point cloud). Even though the Kinect depth data is compelling, particularly compared to other commercially available depth cameras, it is still inherently noisy. Depth mea- surements often fluctuate and depth maps contain numerous ‘holes’ where no readings were obtained. To generate 3D models for use in applications such as gaming, physics, or CAD, higher-level surface geometry needs to be inferred from this noisy point-based data. One simple approach makes strong assumptions about the connectivity of neighboring points within the Kinect depth map to generate a mesh representation. This, however, leads to noisy and low-quality meshes. As importantly, this approach creates an incomplete mesh, from only a single, fixed viewpoint. To create a complete (or even watertight) 3D model, different viewpoints of the physical scene must be captured and fused into a single representation. This talk presents a novel interactive reconstruction system called KinectFusion). The system takes live depth data from a moving Kinect camera and, in real- time, creates a single high-quality, geometrically accurate, 3D model. A user holding a standard Kinect camera can move within any indoor space, and reconstruct a 3D model of the physical scene within seconds. The system continuously tracks the 6 degrees-of-freedom (DOF) pose of the camera and fuses new viewpoints of the scene into a global surface-based representation. A novel GPU pipeline allows for accurate camera tracking and surface reconstruction at interactive real-time rates. We demonstrate core uses of KinectFusion as a low-cost handheld scanner, and present novel interactive methods for segmenting physical objects of interest from the reconstructed scene. We show how a real-time 3D model can be leveraged for geometry-aware augmented reality (AR) and physics- based interactions, where virtual worlds more realistically merge and interact with the real. Placing such systems into an interaction context, where users need to dynamically interact in front of the sensor, reveals a fundamental challenge – no longer can we assume a static scene for camera tracking or reconstruction. We illustrate failure cases caused by a user moving in front of the sensor. We describe new meth ods to overcome these limitations, allowing camera tracking and reconstruction of a static background scene, while simultaneously segmenting, reconstructing and tracking foreground objects, including the user. We use this approach to demonstrate real-time multi-touch inter actions anywhere, allowing a user to appropriate any physical surface, be it planar or non-planar, for touch.

ZoneMinder is a suite of applications intended for use in video camera security applications, including theft prevention and child or family member monitoring. It supports capture, analysis, recording, and monitoring of video data coming from one or more cameras attached to a Linux system. It also features a user-friendly Web interface which allows viewing, archival, review, and deletion of images and movies captured by the cameras. The image analysis system is highly configurable, permitting retention of specific events, while eliminating false positives. ZoneMinder supports both directly connected and network cameras and is built around the definition of a set of individual 'zones' of varying sensitivity and functionality for each camera. This allows the elimination of regions which should be ignored or the definition of areas which will alarm if various thresholds are exceeded in conjunction with other zones. All management, control, and other functions are supported through the Web interface.

Using a small 2-axis motorized camera meant to be mounted on model airplanes, an arduino, and some custom software, they can track faces and keep them in frame in real-time. This is pretty cool, but maybe not quite as groundbreaking as they [...]

If you think there’s a gun inside that camera you’ve been fooled. We just like the juxtaposition of the 1940′s era camera with the iconic sidearms. What you see is a point-and-shoot cameras inside of the classic Leica II body (this is actually a Zorki 1 knockoff). It is much like the Canon AE-1 hack [...]

When [Justin Quinnell] sent in his beer can pinhole camera, we were just floored. The parts are easy to obtain, and the process for building and ’shooting’ with the camera are near effortless.
The really impressive part of this hack is letting your camera sit for 6 months facing the sun. Yes, you read that correct, [...]

[Adam] sent in this cool project. He has modified a Polaroid J66 camera to use modern film. Most of the initial modifications look fairly simple, but things get a little more complicated when they also convert it to a fully manual camera. There is a section that explains a neat little trick of using a [...]
