The Educational Colorimeter Kit (SKU # COLOR-01) contains the following items in a 6" x 4" x 3" clear storage container: Colorimeter LED board; Colorimeter sensor board; Colorimeter shield for the Arduino; 12 laser cut acrylic parts; Hardware for the enclosure (20 screws, 8 nuts and 6 standoffs); 4 x pre-crimped colored wires and housing; Ribbon cable for connecting the Arduino and colorimeter shield; Set of 6 cuvettes; Philips head mini-screwdriver. You can also choose to include an Arduino Uno along with the kit if you do not already have access to one. Once you have the colorimeter kit, follow these 3 steps to get started: Step 1: Assembly
As both an electrical engineer and professional software developer, I'd like to start an open source hardware movement similar to the open source software movement that has currently been happening. I've seen ideas similar to this from other people before, although not well thought out nor articulated correctly, and definitely not the same thoughts I have about the subject. This (somewhat long) post is a summary of my ideas, hoping to get some feedback from other people. Open source software has been around for awhile.
Mesh Potato Click for larger view The Mesh Potato is a device for providing low-cost telephony and Internet in areas where alternative access either doesn’t exist or is too expensive. It is a marriage of a low-cost wireless access point ( AP ) capable of running a mesh networking protocol with an Analog Telephony Adapter ( ATA ).
The DIY Drones development team is proud to bring you the ultimate open source quadcopter and helicopter UAV! ArduCopter's autopilot is based on APM 2 , the most sophisticated IMU-based open source autopilot on the market. It provides full UAV functionality, with scripted waypoints, Ground Station and more.

3/15/12 - The FCam API is now available on the Nokia N9 Linux-based smartphone. See below for details. Overview Computational photography refers broadly to sensing strategies and algorithmic techniques that enhance or extend the capabilities of digital photography. The output of these techniques is an ordinary photograph, but one that could not have been taken by a traditional camera. Representative techniques include high dynamic range imaging, flash-noflash imaging, coded aperture and coded exposure imaging, photography under structured illumination, multi-perspective and panoramic stitching, digital photomontage, all-focus imaging, and light field imaging.
