A Megapixel Time-lapse Camera System

The NSLU2 running OpenWRT and the QuickCam Pro 9000 combine to make a very versatile device. In this post I’m going to describe how to use them as a time-lapse camera which takes photos every ten seconds at 1600×1200 resolution and stores them on a flash drive. The photos occupy anywhere from 80K to 400K each depending on the complexity of the scene. This means that around 10,000 to 15,000 will fit on a 4GByte flash drive, corresponding to 20-40 hours of coverage. All that is required is an NSLU2, a UVC-compatible webcam, a flash drive, and an OpenWRT firmware build, which is available here. A brief sample movie (30 seconds, 8.5Mbytes, DivX) is available here.
