Pamban Bridge Photograhps
The Pamban Bridge ( Tamil: பாம்பன் பாலம்), is a cantilever bridge on the Palk Strait which connects the town of Rameswaram on Pamban Island to mainland India. The bridge refers to both the road bridge and the cantilever railway bridge, though primarily it means the latter. Opened in 1914, it was India’s first sea bridge, and was the longest sea bridge in India till 2010. The rail bridge is for the most part, a conventional bridge resting on concrete piers, but has a double leaf bascule section midway, which can be raised to let ships and barges pass through. On 24 February 2014, the Pamban Bridge marked its 100th anniversary. – Pamban Bridge – Wikipedia

Time Lapse Video using CubieTruck and Nikon D200
Today it was whole lot fun exploring the possibilities with Raspberry Pi and DSLR for taking time lapse video. Latter I moved from Raspberry Pi to CubieTruck so that I can attach hard drive for large storage capacity. I found a small command line utility gphoto which can be used as remote control for a DSLR. I can use the utility to click a photo and stream the picture to the Pi.
The version I found on the apt-get was little old so I had to compile my own version. Then you can play around with the gphoto command to play around.

Working with Raspberry Pi Camera Rev 1.3
Fastest online delivery I had ever experienced was with Raspberry Pi Camera from RS Components. I received the package in 3days for a shipment fee of 8 USD.
The setup was very straight forward and simple, just follow the link. A sample shot taken using the camera, it has come out bad that is due to me not fixing the camera properly.
Going to attempt time lapse photography… will keep you posted 😉
