Planning - Choosing Equipment

One consideration I have to make for this project is the equipment.
In choosing the equipment I have 2 major options.

Firstly I could use a video camera and record for a few hours although this will take up a lot of storage space. Then in post you would have to speed it up to get the time-lapse effect.
Secondly I could use an digital SLR to take high resolution still images and then use a combination of Adobe After Effects and Adobe Premier to form the video.

I chose to use a Canon 600d slr to shoot the project. I chose this as I own one and it produces high resolution stills.

One issue with this is that I need an Intervalometer controller to activate the shutter at the desired interval. For this I have 3 options.
The first of these is to use a laptop and the EOS utility software that came with the camera. The downside to this is that i need a laptop with me which may not be the most practical setup as it requires me to carry a laptop about and the laptop battery may not last long enough.
The second option to this is to buy a dedicated intervalometer controller. The downside to this is that it requires me to pay for it.
The third option which i chose is to use magic lantern which is an open source hack for the camera which adds time-lapse features for the camera. I chose this as it was free, easy to use and easy to install on the camera.
